Obesity

Obesity, a risk factor for nonalcoholic fatty liver disease (NAFLD) and a prevalent comorbidity among people with cirrhosis of all etiologies, is associated with a number of untoward health outcomes, and weight loss is an important goal, according to a clinical practice update from the American Gastroenterological Association. According to one study cited in the update, approximately 30% of patients with cirrhosis have comorbid obesity, and this figure may increase even further as the epidemic of NAFLD progresses.

For obese patients with cirrhosis, weight loss “is an important therapeutic goal” because obesity heightens risks of portal vein thrombosis, portal hypertension, hepatocellular carcinoma, liver failure in acute on chronic liver disease, and other concerns. Despite no longer being an absolute contraindication, obesity can also complicate liver transplantation considerations, Heather Patton, MD, of the Veterans Affairs San Diego Healthcare System and associates wrote in Clinical Gastroenterology and Hepatology. Consideration of individuals with cirrhosis, however, requires careful scrutiny of surgical candidacy, appropriate resources for care of patients with advanced liver disease, and a high-volume bariatric surgical center given the inherent risks of surgical procedures in this patient population.

For patients with cirrhosis and obesity, laparoscopic sleeve gastrectomy is probably the best option for bariatric surgery because it preserves endoscopic access to the biliary tree, facilitates gradual weight loss, and does not cause malabsorption, according to the update.

Clinicians and patients should time bariatric surgery based on liver disease stage – for patients with decompensated disease, surgery should be performed only at the same time as or after liver transplantation, the experts wrote. Clinicians should also evaluate candidacy for liver transplantation before bariatric surgery “so that patients who are ineligible for transplant (and their families) have a clear understanding of this, avoiding the need for the medical team to address this issue urgently if the patient’s condition deteriorates postoperatively.”

One review suggested that bariatric surgery is “the most effective and durable” means of weight loss, according to the authors of the update; however, another review suggested increased surgical risk for bariatric surgery among patients with cirrhosis, so the update’s authors advised individualized risk-benefit assessments. These assessments are made even more complicated by scarcity of relevant randomized trial data, so the experts identified PubMed-indexed, peer-reviewed articles published between 2000 and 2020 and used these to make 10 best practice advice statements for bariatric surgery in obese patients with cirrhosis.

The surgical, anesthesia, and medical teams must be well versed in assessing and operating on patients with portal hypertension and cirrhosis and in managing these patients postoperatively, the experts wrote. The preoperative assessment should include cirrhosis status (compensated versus decompensated), the presence and severity of sarcopenia, ascites, and portal hypertension, and candidacy for liver transplantation. It is vital to check for clinically significant portal hypertension (CSPH) because endoscopic devices should not be used in patients with gastric and/or esophageal varices. To do so, upper endoscopy and cross-sectional imaging are advised, pending better data on noninvasive assessment methods. For patients without CSPH, endoscopic bariatric treatment can be somewhat less effective for weight loss but also might be less likely to lead to postoperative complications. However, head-to-head and long-term safety data are not yet available.

The experts also noted that bariatric surgery increases the effects (blood levels) of alcohol and can increase patients’ risk for developing an alcohol use disorder. Therefore, clinicians should carefully the history of alcohol use and repeatedly educate patients about the risks of consuming alcohol after bariatric surgery. According to a study from 2012 and a review from 2015, male sex, younger age, less social support, and regular or “problematic” alcohol use before bariatric surgery heighten the risk for developing an alcohol use disorder afterward, the experts noted.

Younger adolescents who underwent metabolic and bariatric surgery had outcomes similar to those of older adolescents undergoing the same procedure, according to recent research in Pediatrics.

Five years after metabolic and bariatric surgery (MBS), adolescents between ages 13 and 15 years had similar outcomes with regard to reduction in body mass index percentage, hypertension and dyslipidemia, and improved quality of life, compared with adolescents between ages 16 and 19 years, according to Sarah B. Ogle, DO, MS, of Children’s Hospital Colorado at the University of Colorado at Denver, Aurora, and colleagues.

“These results appear promising for the treatment of severe obesity in young patients,” Dr. Ogle and colleagues wrote, “however, further controlled studies are needed to fully evaluate the timing of surgery and extended long-term durability.”

The researchers analyzed the outcomes of adolescents enrolled in the Teen–Longitudinal Assessment of Bariatric Surgery who were aged 19 years or younger and underwent MBS between March 2007 and December 2011 at five U.S. centers. In the group of younger adolescents (66 participants), the mean age at surgery was 15.1 years, while the group of older adolescents (162 participants) had a mean age of 17.7 years at the time of surgery. Both groups consisted mostly of White (71.6%-72.7%) girls (72.7%-75.9%) who were morbidly obese (mean BMI, 52.4-53.1 kg/m²). With regard to baseline comorbidities, about three-quarters of participants in the younger (72.4%) and older (77.0%) adolescent groups had dyslipidemia. More than one-quarter of younger adolescents had hypertension (27.3%) compared with more than one-third of older adolescents (37.1%). The prevalence of type 2 diabetes was 10.6% in the younger adolescent group and 13.6% among older adolescents.

At 5-year follow-up, there was a similar BMI reduction maintained from baseline in the younger adolescent group (–22.2%; 95% confidence interval, –26.2% to –18.2%) and the older adolescent group (–24.6%; 95% CI, –27.7% to –22.5%; P = .59). There was a similar number of participants who had remission of dyslipidemia at 5 years in the younger adolescent group (61%; 95% CI, 46.3%-81.1%) and older adolescent group (58%; 95% CI, 48.0%-68.9%; P = .74). In participants with hypertension, 77% of younger adolescents (95% CI, 57.1%-100.0%) and 67% of older adolescents (95% CI, 54.5%-81.5%) achieved remission at 5 years after MBS, which showed no significant differences after adjustment (P = .84). For participants with type 2 diabetes at baseline, 83% of younger adolescents (6 participants) and 87% of older adolescents (15 participants) experienced remission by 5 years after surgery. Participants in both younger and older adolescent groups had similar quality of life scores at 5 years after surgery. When analyzing nutritional abnormalities, the researchers found younger adolescents in the group were less at risk for elevated transferrin levels (prevalence ratio, 0.52; P = .048) as well as less likely to have low vitamin D levels (prevalence ratio, 0.8; P = .034).
 

Pediatricians still concerned about safety

In an interview, Kelly A. Curran, MD, MA, assistant professor of pediatrics at University of Oklahoma Children’s Hospital in Oklahoma City, said that the findings by Dr. Ogle and colleagues add to a “growing body of literature about the importance of bariatric surgery for both younger and older adolescents.

“While many often see bariatric surgery as a ‘last resort,’ this study shows good outcomes in resolving obesity-related health conditions in both young and older teens over time – and something that should be considered more frequently than it is currently being used,” she said.

Guidelines from the American Society for Metabolic and Bariatric Surgery removed a restriction for younger age before a patient undergoes MBS, and a policy statement from the American Academy of Pediatrics encouraged increased use and access to MBS for younger adolescents. However, Dr. Curran noted that many pediatricians are still concerned about performing MBS on younger adolescents.

“Despite growing evidence of safety, I think many pediatricians worry about the potential for unintended consequences and potential impact on adolescent development or for lifelong micronutrition deficiencies – especially as there are no longitudinal studies over a lifetime,” she said.

“[W]ith the growing obesity epidemic and the long-term consequences of obesity on health and quality of life – the potential to help impact adolescents’ lives – for now and for the future – is impressive,” Dr. Curran said, acknowledging the ethical challenges involved with performing MBS on a patient who may be too young to understand the full risks and benefits of surgery.

“There are always inherent ethical challenges in providing surgery for patients too young to understand – we are asking parents to act in their child’s best interests, which may be murky to elucidate,” she explained. “While there is [a] growing body of literature around the safety and efficacy in bariatric surgery for children and adolescents, there are still many unanswered questions that remain – especially for parents. Parents can feel trapped in between these two choices – have children undergo surgery or stick with potentially less effective medical management.”

The limitations of the study include its observational nature, small sample size of some comorbidities, and a lack of diversity among participants, most of whom were White and female. In addition, “long-term studies examining the impact of bariatric surgery during adolescence would be important to give more perspective and guidance on the risks and benefits for teens,” Dr. Curran said.

The study was funded by the National Institutes of Health and grants from the National Institute of Diabetes and Digestive and Kidney Diseases as well as grants from Cincinnati Children’s Hospital Medical Center, Nationwide Children’s Hospital, Texas Children’s Hospital and Baylor College of Medicine, University of Pittsburgh, and the University of Alabama at Birmingham. The authors and Dr. Curran reported no conflicts of interest.

A small, single-center randomized trial of patients with obesity and advanced type 2 diabetes, defined as diabetes for ≥ 5 years and A1c ≥ 7%, found that a quarter to a half of patients who had metabolic surgery had diabetes remission (cure) that lasted 5-9 years.

That is, of the 60 randomized patients, 50% who had biliopancreatic diversion and 25% who had Roux-en-Y gastric bypass – but none who had received current medical therapy – still had diabetes remission a decade later.

Until now, there had only been 5-year follow-up data from this and similar trials, Geltrude Mingrone, MD, PhD, and colleagues noted in the study published online Jan. 23 in The Lancet.

These results provide “the most robust scientific evidence yet that full-blown type 2 diabetes is a curable disease, not inevitably progressive, and irreversible,” senior author Francesco Rubino, MD, chair of bariatric and metabolic surgery at King’s College London, said in a statement from his institution.

“The results of this trial will make a noticeable difference in the field and convince even the most skeptical of clinicians about the role of metabolic surgery as part of optimal care for their patients with difficult to control type 2 diabetes,” predicted two editorialists.

Alexander D. Miras, PhD, section of metabolism, digestion, and reproduction, Imperial College London, and Carel le Roux, MBChB, PhD, of the Diabetes Complications Research Centre, University College Dublin, penned the accompanying commentary.

Patients who had metabolic surgery also had greater weight loss, reduced medication use, lower cardiovascular risk, better quality of life, and a lower incidence of diabetes-related complications compared with those who received medical therapy.

“Clinicians and policymakers should ensure that metabolic surgery is appropriately considered in the management of patients with obesity and type 2 diabetes,” advised Dr. Mingrone of King’s College London and the Catholic University of Rome, and colleagues.
 

“Reassuring results, will make a difference in the field”

“It is reassuring that we now have 10-year data showing greater efficacy of metabolic surgery than conventional medical therapy,” Dr. Miras and Dr. le Roux wrote in their commentary.

There were no unexpected risks associated with surgery, they noted, and the findings are consistent with those of 12 other randomized controlled trials in the past 12 years.

“New generations of diabetologists are now more open to the use of metabolic surgery for patients with suboptimal responses to medical treatments,” they wrote, rather than endlessly intensifying insulin and blaming poor response on poor compliance.

And Dr. Miras and Dr. le Roux “eagerly await” 10-year data from the 150-patient STAMPEDE trial – which is examining sleeve gastrectomy, currently the most widely performed bariatric procedure, as well as Roux-en-Y gastric bypass and medical therapy – following the 5-year results published in 2017.  
 

Diabetes for at least 5 years, mid 40s, half on insulin

Dr. Mingrone and colleagues previously reported 5-year findings from the 60 patients with obesity and advanced diabetes who were seen in a single center in Rome and randomized to three treatments (20 in each group) in 2009-2011.

Biliopancreatic diversion “remains infrequently performed but is still considered the best operation for glycemic control,” the researchers noted.

The primary endpoint was diabetes remission at 2 years (fasting plasma glucose < 100 mg/dL [5.6 mmol/L] and A1c < 6.5%) without the need for ongoing pharmacological treatment for at least 1 year.

Patients were a mean age of 44 years and had a mean body mass index of 44 kg/m^2. About half were men. They had diabetes for a mean of 5.8 years and an average A1c of 8.6%. About half were taking insulin.

Patient retention rate was high (95%) and trial outcomes were assessed by nonsurgeons.

At 10 years, patients’ mean A1c had dropped to 6.4%, 6.7%, and 7.6%, in the biliopancreatic diversion, Roux-en-Y gastric bypass, and medical therapy groups, respectively; only 2.5% of patients in the surgery groups, versus 53% in the medical therapy group, required insulin.

At study end, patients in the surgery groups had lost about 29% of their initial weight versus a weight loss of 4.2% in the medical therapy group.
 

First 2 years after surgery is key

“We also learnt that patients who do not go into remission after 2 years are very unlikely to ever do so,” Dr. Miras and Dr. le Roux observed, which “might help us to intensify modern and potent glucose-lowering therapies like SGLT2 inhibitors and GLP-1 receptor agonists earlier after metabolic surgery.”

Ten of 19 patients (53%) in the biliopancreatic diversion group and 10 of 15 patients (67%) in the Roux-en-Y gastric bypass group who had diabetes remission at 2 years had a diabetes relapse, but at 10 years, they all had adequate glycemic control (mean A1c 6.7%), despite drastically reduced use of diabetes medications.

The two patients who crossed over to surgery from the medical therapy group had postoperative diabetes remission, which was maintained at 10 years in one patient.
 

Better risk-to-benefit ratio with Roux-en-y gastric bypass

No patient in the medical therapy group had a serious adverse event, but one patient in each surgery group had deep vein thrombosis or pulmonary embolism, and one patient in the biliopancreatic diversion group had an episode of atrial fibrillation. There were no late surgical complications.

Iron deficiency and mild osteopenia occurred in both surgical groups, but were more common in the biliopancreatic diversion group. And osteoporosis, transient nyctalopia (night blindness) due to vitamin A deficiency, and kidney stones were observed only with biliopancreatic diversion.

This suggests that despite the greater antidiabetic potential of biliopancreatic diversion, Roux-en-Y gastric bypass might have a more favorable risk-to-benefit profile as a standard surgical option for the treatment of type 2 diabetes, Dr. Mingrone and colleagues concluded.

The authors and Dr. Miras have reported no relevant financial relationships. Dr. le Roux has reported receiving funding from the Science Foundation Ireland, the Health Research Board, and the Irish Research Council for type 2 diabetes research, and serves on several advisory boards outside of the scope of the current study.

A small, single-center randomized trial of patients with obesity and advanced type 2 diabetes, defined as diabetes for ≥ 5 years and A1c ≥ 7%, found that a quarter to a half of patients who had metabolic surgery had diabetes remission (cure) that lasted 5-9 years.

That is, of the 60 randomized patients, 50% who had biliopancreatic diversion and 25% who had Roux-en-Y gastric bypass – but none who had received current medical therapy – still had diabetes remission a decade later.

Until now, there had only been 5-year follow-up data from this and similar trials, Geltrude Mingrone, MD, PhD, and colleagues noted in the study published online Jan. 23 in The Lancet.

These results provide “the most robust scientific evidence yet that full-blown type 2 diabetes is a curable disease, not inevitably progressive, and irreversible,” senior author Francesco Rubino, MD, chair of bariatric and metabolic surgery at King’s College London, said in a statement from his institution.

“The results of this trial will make a noticeable difference in the field and convince even the most skeptical of clinicians about the role of metabolic surgery as part of optimal care for their patients with difficult to control type 2 diabetes,” predicted two editorialists.

Alexander D. Miras, PhD, section of metabolism, digestion, and reproduction, Imperial College London, and Carel le Roux, MBChB, PhD, of the Diabetes Complications Research Centre, University College Dublin, penned the accompanying commentary.

Patients who had metabolic surgery also had greater weight loss, reduced medication use, lower cardiovascular risk, better quality of life, and a lower incidence of diabetes-related complications compared with those who received medical therapy.

“Clinicians and policymakers should ensure that metabolic surgery is appropriately considered in the management of patients with obesity and type 2 diabetes,” advised Dr. Mingrone of King’s College London and the Catholic University of Rome, and colleagues.
 

“Reassuring results, will make a difference in the field”

“It is reassuring that we now have 10-year data showing greater efficacy of metabolic surgery than conventional medical therapy,” Dr. Miras and Dr. le Roux wrote in their commentary.

There were no unexpected risks associated with surgery, they noted, and the findings are consistent with those of 12 other randomized controlled trials in the past 12 years.

“New generations of diabetologists are now more open to the use of metabolic surgery for patients with suboptimal responses to medical treatments,” they wrote, rather than endlessly intensifying insulin and blaming poor response on poor compliance.

And Dr. Miras and Dr. le Roux “eagerly await” 10-year data from the 150-patient STAMPEDE trial – which is examining sleeve gastrectomy, currently the most widely performed bariatric procedure, as well as Roux-en-Y gastric bypass and medical therapy – following the 5-year results published in 2017.  
 

Diabetes for at least 5 years, mid 40s, half on insulin

Dr. Mingrone and colleagues previously reported 5-year findings from the 60 patients with obesity and advanced diabetes who were seen in a single center in Rome and randomized to three treatments (20 in each group) in 2009-2011.

Biliopancreatic diversion “remains infrequently performed but is still considered the best operation for glycemic control,” the researchers noted.

The primary endpoint was diabetes remission at 2 years (fasting plasma glucose < 100 mg/dL [5.6 mmol/L] and A1c < 6.5%) without the need for ongoing pharmacological treatment for at least 1 year.

Patients were a mean age of 44 years and had a mean body mass index of 44 kg/m^2. About half were men. They had diabetes for a mean of 5.8 years and an average A1c of 8.6%. About half were taking insulin.

Patient retention rate was high (95%) and trial outcomes were assessed by nonsurgeons.

At 10 years, patients’ mean A1c had dropped to 6.4%, 6.7%, and 7.6%, in the biliopancreatic diversion, Roux-en-Y gastric bypass, and medical therapy groups, respectively; only 2.5% of patients in the surgery groups, versus 53% in the medical therapy group, required insulin.

At study end, patients in the surgery groups had lost about 29% of their initial weight versus a weight loss of 4.2% in the medical therapy group.
 

First 2 years after surgery is key

“We also learnt that patients who do not go into remission after 2 years are very unlikely to ever do so,” Dr. Miras and Dr. le Roux observed, which “might help us to intensify modern and potent glucose-lowering therapies like SGLT2 inhibitors and GLP-1 receptor agonists earlier after metabolic surgery.”

Ten of 19 patients (53%) in the biliopancreatic diversion group and 10 of 15 patients (67%) in the Roux-en-Y gastric bypass group who had diabetes remission at 2 years had a diabetes relapse, but at 10 years, they all had adequate glycemic control (mean A1c 6.7%), despite drastically reduced use of diabetes medications.

Cardiovascular disease and related risk factors can be common among male breast cancer patients, suggests a small study in this rare malignancy.

Among 24 male breast cancer patients evaluated over a decade in the Washington area, 88% were obese or overweight, 58% had hypertension, and 54% had hyperlipidemia.

Tachyarrhythmia existed in 8% of the men before cancer treatment and developed in 13% during treatment.

Two patients had preexisting heart failure, two patients developed the disease after treatment, and another two patients experienced a decline in left ventricular ejection fraction during the course of their cancer treatment.

“Our hope is that treating male breast cancer patients becomes a multidisciplinary approach where oncologists recruit their cardio-oncologist counterparts to mitigate cardiovascular risk factors, so patients live a long and healthy life after cancer treatment,” said Michael Ibrahim, one of the study authors and a 4th-year medical student at Georgetown University in Washington.

The data were presented Jan. 25 as part of the American College of Cardiology’s Advancing the Cardiovascular Care of the Oncology Patient virtual course, which is hosting live sessions Feb. 5-6.

Although the association between cardiovascular disease and breast cancer is well documented in female breast cancer patients, there is little evidence in their male counterparts, especially African Americans, Mr. Ibrahim noted.

To provide some context, Mr. Ibrahim highlighted a 2018 report in nearly 3,500 female breast cancer patients, ages 40-79, in whom 52% were obese/overweight, 35% had hypertension, and 28% had hyperlipidemia.

Diabetes was present in 7.5% of the women, which was roughly equivalent to the 8% found among the men, Mr. Ibrahim said. The men were of similar age (38-79 years), with 42% being African American, 29% White, 4% Hispanic, and 25% another ethnicity.

Importantly, half of the men had a family history of breast cancer, and two were positive for a mutation in the BRCA gene.

A 2017 in-depth review of male breast cancer cites advancing age, hormonal imbalance, radiation exposure, and family history of breast cancer as key risk factors for the development of the disease, but the “most relevant risk factor” is a mutation in the BRCA2 gene.

Male breast cancer accounts for less than 1% of all breast cancers, but the incidence is rising and, in some patient groups, reaching 15% over their lifetimes, the paper notes. Additionally, these patients are at special risk for developing a second cancer.

Remarkably, 25% of men in the D.C. cohort were diagnosed with a second primary malignancy, 13% a third primary cancer, and 4% a fourth primary cancer, Mr. Ibrahim reported. “This goes to show that male breast cancer patients should routinely undergo cancer screening,” he said.

The initial diagnosis was invasive ductal carcinoma in 79% of the men, with the remaining ductal carcinoma in situ. All patients underwent mastectomy, 17% had anthracycline chemotherapy, 8% received HER2-targeted therapy, 16% had radiation, and 71% received hormone therapy.

In terms of cardiovascular management, statins were the most prescribed medication (46%), followed by antiplatelet therapy (42%) and angiotensin-converting enzyme inhibitors/angiotensin-receptor blockers (38%).

An implantable cardioverter defibrillator/pacemaker was the most common intervention (16%), followed by bypass surgery in 8% and coronary angioplasty in 4%.

Mr. Ibrahim noted that the study was limited by the small sample size and that further research is needed to understand the risk of preexisting cardiovascular disease on long-term outcomes as well as the cardiotoxic effects of chemoradiation in male breast cancer patients.

In a statement, Mr. Ibrahim reiterated the need for a multidisciplinary cancer care team to evaluate patients’ cardiovascular risk prior to and through cancer treatment.

“On a more personal level, cancer patients are already surprised by their cancer diagnosis,” he added. “Similar to the pretreatment consultation with radiation oncology, breast surgery, and medical oncology, an upfront cardiovascular risk assessment provides greater comfort and further minimizes psychological surprise with cardiovascular complications going into cancer treatment.”

The authors have disclosed no relevant financial relationships.

The relationship between obesity and overweight and breast cancer has some elements of mystery. But this is not one of them: in metastatic breast cancer (MBC), excess body weight does not negatively influence outcomes.

Multiple small studies have demonstrated this point, and now, for the first time, a large multicenter cohort analysis indicates the same.

Using medical records from 18 French comprehensive cancer centers, investigators reviewed body mass index (BMI) and overall survival (OS) data for nearly 13,000 women. The median OS was 47.4 months, and the median follow-up was about the same length of time. The team reports that obesity and overweight “were clearly not associated with prognosis.”

However, underweight was independently associated with worse OS (median, 33 months; hazard ratio, 1.14; 95% confidence interval, 1.02-1.27), report Khalil Saleh, MD, of Gustave Roussy in Villejuif, France, and colleagues.

In short, obesity or overweight had no effect on the primary outcome of OS, but underweight did.

“Underweight should be the subject of clinical attention at the time of diagnosis of MBC, and specific management should be implemented,” said study author Elise Deluche, MD, of CHU de Limoges, in an email to this news organization.

The study was published online Dec. 1 in The Breast.

“It’s really wonderful to have such a large cohort to look at this question,” said Jennifer Ligibel, MD, of the Dana-Farber Cancer Institute, Boston, who was asked for comment.

Is this another case of obesity paradox in cancer (as in renal cell carcinoma and melanoma, where excess weight is tied to better cancer-specific survival)?

No, said Dr. Ligibel: “There’s no hint at all [in this study] that people with obesity and overweight did better. … They just didn’t have worse outcomes.”

The study authors point out that the opposite is true in early-stage breast cancer. In this patient population, excess weight is associated with worse outcomes.

For example, in a 2014 meta-analysis of 82 follow-up studies in early-stage disease, obesity was associated with higher total mortality (relative risk, 1.41) and breast cancer–specific mortality (RR, 1.35) as compared to normal weight.

Why is there such a contrast between early- and late-stage disease?

“I don’t think we know exactly,” answered Dr. Ligibel. “It may be that, with breast cancer, as disease progresses, the pathways through which lifestyle may impact breast cancer may become less important.

“Obesity and overweight are associated with cancer risk in general,” said Dr. Ligibel, citing more than a dozen malignancies, including breast cancer.

But there is also an age element. Overweight or obesity is an independent predictor of breast cancer risk in postmenopausal women, but in premenopausal women, it appears to be protective. “Historically, there has been a lower risk of hormone receptor–positive breast cancer in women with obesity at younger ages that we don’t completely understand,” Dr. Ligibel noted.

That age-based difference is a conundrum, said Dr. Ligibel: “People have been trying to figure that out for a long time.”

Dr. Ligibel summarized as follows:

“There is a clear relationship between obesity and the risk of developing breast cancer; there is a clear relationship in early breast cancer that obesity is related to an increased risk of occurrence and mortality. What we are seeing from this study is that, by the time you get to metastatic breast cancer, body weight does not seem to play as important a role.”
 

More study details

The findings come from the French National Epidemiological Strategy and Medical Economics–Metastatic Breast Cancer observational cohort, which includes 22,000-plus consecutive patients who were newly diagnosed with metastatic disease between 2008 and 2016.

A total of 12,999 women for whom BMI data were available when they were diagnosed with metastatic breast cancer were selected for analysis. They were divided into four groups, according to World Health Organization classification: underweight (BMI <18.5 kg/m²), normal weight (18.5-24.9), overweight (25.0-29.9), and obese (≥30.0).

A total of 20% of women were obese, which is a much lower percentage than the 40%-50% that would be expected in a comparable American cohort, said Dr. Ligibel. Also, 5% of the French cohort was underweight.

Multivariate Cox analyses were carried out for OS and for first-line progression-free survival (PFS).

As noted above, underweight was independently associated with a worse OS. It was also tied to worse first-line PFS (HR, 1.11; 95% CI, 1.01-1.22). Overweight or obesity had no effect.

“Patients with a low BMI had more visceral metastases and a greater number of metastatic sites,” pointed out study author Dr. Deluche. “We attribute the fat loss in patients with metastatic breast cancer to aggressive tumor behavior with a higher energy requirement.”

The study authors also observe that in early-stage breast cancer, underweight is not associated with overall or breast cancer–specific survival. “Underweight at metastatic diagnosis seems to have a different significance and impact,” they write. The French team also observes that, in other cancers, underweight is also an adverse prognostic factor and has been associated with a higher risk for death.

The study authors acknowledge that BMI has limitations as a measure of body type. “BMI alone cannot estimate a woman’s muscle mass and adiposity,” they observe. The suggestion is that, among women with a similar BMI, some might be muscular, whereas others might have more body fat.

Multiple study authors report financial ties to industry, including pharmaceutical companies with drugs used in breast cancer. The database used in the study receives financial support from AstraZeneca, Daiichi Sankyo, Eisai, MSD, Pfizer, and Roche. Dr. Ligibel reports no relevant financial relationships.

Is this another case of obesity paradox in cancer (as in renal cell carcinoma and melanoma, where excess weight is tied to better cancer-specific survival)?

No, said Dr. Ligibel: “There’s no hint at all [in this study] that people with obesity and overweight did better. … They just didn’t have worse outcomes.”

The study authors point out that the opposite is true in early-stage breast cancer. In this patient population, excess weight is associated with worse outcomes.

For example, in a 2014 meta-analysis of 82 follow-up studies in early-stage disease, obesity was associated with higher total mortality (relative risk, 1.41) and breast cancer–specific mortality (RR, 1.35) as compared to normal weight.

Why is there such a contrast between early- and late-stage disease?

“I don’t think we know exactly,” answered Dr. Ligibel. “It may be that, with breast cancer, as disease progresses, the pathways through which lifestyle may impact breast cancer may become less important.

“Obesity and overweight are associated with cancer risk in general,” said Dr. Ligibel, citing more than a dozen malignancies, including breast cancer.

But there is also an age element. Overweight or obesity is an independent predictor of breast cancer risk in postmenopausal women, but in premenopausal women, it appears to be protective. “Historically, there has been a lower risk of hormone receptor–positive breast cancer in women with obesity at younger ages that we don’t completely understand,” Dr. Ligibel noted.

That age-based difference is a conundrum, said Dr. Ligibel: “People have been trying to figure that out for a long time.”

Dr. Ligibel summarized as follows:

“There is a clear relationship between obesity and the risk of developing breast cancer; there is a clear relationship in early breast cancer that obesity is related to an increased risk of occurrence and mortality. What we are seeing from this study is that, by the time you get to metastatic breast cancer, body weight does not seem to play as important a role.”
 

More study details

The findings come from the French National Epidemiological Strategy and Medical Economics–Metastatic Breast Cancer observational cohort, which includes 22,000-plus consecutive patients who were newly diagnosed with metastatic disease between 2008 and 2016.

A total of 12,999 women for whom BMI data were available when they were diagnosed with metastatic breast cancer were selected for analysis. They were divided into four groups, according to World Health Organization classification: underweight (BMI <18.5 kg/m²), normal weight (18.5-24.9), overweight (25.0-29.9), and obese (≥30.0).

A total of 20% of women were obese, which is a much lower percentage than the 40%-50% that would be expected in a comparable American cohort, said Dr. Ligibel. Also, 5% of the French cohort was underweight.

Multivariate Cox analyses were carried out for OS and for first-line progression-free survival (PFS).

As noted above, underweight was independently associated with a worse OS. It was also tied to worse first-line PFS (HR, 1.11; 95% CI, 1.01-1.22). Overweight or obesity had no effect.

“Patients with a low BMI had more visceral metastases and a greater number of metastatic sites,” pointed out study author Dr. Deluche. “We attribute the fat loss in patients with metastatic breast cancer to aggressive tumor behavior with a higher energy requirement.”

The study authors also observe that in early-stage breast cancer, underweight is not associated with overall or breast cancer–specific survival. “Underweight at metastatic diagnosis seems to have a different significance and impact,” they write. The French team also observes that, in other cancers, underweight is also an adverse prognostic factor and has been associated with a higher risk for death.

The study authors acknowledge that BMI has limitations as a measure of body type. “BMI alone cannot estimate a woman’s muscle mass and adiposity,” they observe. The suggestion is that, among women with a similar BMI, some might be muscular, whereas others might have more body fat.

Multiple study authors report financial ties to industry, including pharmaceutical companies with drugs used in breast cancer. The database used in the study receives financial support from AstraZeneca, Daiichi Sankyo, Eisai, MSD, Pfizer, and Roche. Dr. Ligibel reports no relevant financial relationships.

The relationship between obesity and overweight and breast cancer has some elements of mystery. But this is not one of them: in metastatic breast cancer (MBC), excess body weight does not negatively influence outcomes.

Multiple small studies have demonstrated this point, and now, for the first time, a large multicenter cohort analysis indicates the same.

Using medical records from 18 French comprehensive cancer centers, investigators reviewed body mass index (BMI) and overall survival (OS) data for nearly 13,000 women. The median OS was 47.4 months, and the median follow-up was about the same length of time. The team reports that obesity and overweight “were clearly not associated with prognosis.”

However, underweight was independently associated with worse OS (median, 33 months; hazard ratio, 1.14; 95% confidence interval, 1.02-1.27), report Khalil Saleh, MD, of Gustave Roussy in Villejuif, France, and colleagues.

In short, obesity or overweight had no effect on the primary outcome of OS, but underweight did.

“Underweight should be the subject of clinical attention at the time of diagnosis of MBC, and specific management should be implemented,” said study author Elise Deluche, MD, of CHU de Limoges, in an email to this news organization.

The study was published online Dec. 1 in The Breast.

Physical activity mitigated the impact of high body mass index (BMI) on cardiovascular risk factors, but not overall cardiovascular disease risk, according to an observational study of half a million individuals.

Despite the historically high rates of overweight and obesity worldwide, some evidence suggests that cardiorespiratory fitness could reduce the effects of excess weight on cardiovascular disease risk, wrote Pedro L. Valenzuela, PhD, of the University of Alcalá, Madrid, and colleagues.

“To clarify the existence of the ‘fat-but-fit’ [or ‘elevated BMI but active’] paradox, in this observational study, we assessed the joint association between different BMI categories and physical activity levels, respectively, and the prevalence of major CVD risk factors,” they said.

In a population-based cohort study published in the European Journal of Preventive Cardiology, the researchers identified 527,662 adults aged 18-64 years who were insured by an occupational risk–prevention company and underwent annual medical exams as part of their coverage. The average age of the participants was 42 years, 32% were women, and the average BMI was 26.2 kg/m².

The participants were categorized as normal weight (42%), overweight (41%), and obese (18%), and their activity levels were categorized as inactive (64%), insufficiently active (12%), and regularly active (24%). In addition, 30% had hypercholesterolemia, 15% had hypertension, and 3% had diabetes.

Overall, compared with inactivity, insufficient activity or regular activity reduced CVD risk factors within each BMI category, and subgroups. “However, regular/insufficient PA did not compensate for the negative effects of overweight/obesity, as individuals with overweight/obesity were at greater CVD risk than their peers with normal weight, irrespective of PA levels,” the researchers said. Compared with active normal-weight men, the odds ratios for hypertension in active overweight men and active obese men were 1.98 and 4.93, respectively; the odds ratios for hypercholesterolemia were 1.61 and 2.03, respectively, and the odds ratios for diabetes were 1.33 and 3.62, respectively (P < .001 for all). Trends were similar for women.

The study results were limited by the cross-sectional design; inability to control for participants’ diet, and the reliance of self-reports of leisure-time physical activity. However, the findings were strengthened by the large sample size and “refute the notion that a physically active lifestyle can completely negate the deleterious effects of overweight/obesity,” the researchers said.

Although increasing physical activity should remain a priority for health policies, “weight loss per se should remain a primary target for health policies aimed at reducing CVD risk in people with overweight/obesity,” they concluded.
 

Interpret findings with caution

“With the ever-increasing public health problem of overweight and obesity, it is useful to assess any measure or measures that can have a favorable or adverse effect on cardiometabolic risk factors and the risk of CVD” Prakash Deedwania, MD, of the University of California, San Francisco, said in an interview.

Dr. Deedwania said he was not entirely surprised by the study findings. “The investigators have correlated only the self-reported level of physical activity (which is not always reliable) to the presence of three cardiac risk factors: hypertension, hypercholesterolemia, and diabetes.”

The study “is not comparable to prior reports that had shown a favorable impact of carefully assessed cardiorespiratory fitness with the risk of CVD,” Dr. Deedwania noted. “However, this is one of the largest population-wide surveillance studies of more than a half million active workers across Spain, and it does show that, despite self-reported physical activity, overweight and obesity are associated with higher risks of hypertension, diabetes, and hypercholesterolemia,” he explained.

“The main message of these findings is that, although physical activity does have a dose-dependent favorable impact on CV risk, the main public health intervention to reduce the risk of CV risk should focus on weight loss in overweight and obese individuals,” Dr. Deedwania emphasized.

“Future studies should focus on comparing various levels of daily activities and routine exercise such as walking, bicycling, etc., with the beneficial impact on cardiometabolic risk factors in overweight and obese individuals,” he said.

Dr. Valenzuela disclosed support from the University of Alcalá. Research by corresponding author Dr. Lucia was funded by grants from Spanish Ministry of Science and Innovation and Fondos FEDER. Dr. Deedwania had no financial conflicts to disclose.

The incidence of idiopathic intracranial hypertension (IIH) – characterized by increased cerebrospinal fluid (CSF) pressure – is rising considerably, corresponding to population increases in body mass index (BMI), a new study has shown. “The condition is associated with a high rate of health care utilization, so the increasing incidence has important implications for health care professionals and policy makers in addressing the associated comorbidities,” said senior author William Owen Pickrell, PhD, Swansea University (Wales).

The study was published online Jan. 20 in Neurology.

IIH is a condition of unknown etiology that is strongly associated with obesity, the researchers noted. Predominantly affecting women of childbearing age, it causes chronic disabling headaches, visual disturbance, and in a minority of patients, permanent visual loss. The definitive management is weight loss, but a minority of patients require surgery to preserve vision.

People with IIH potentially have high rates of health care utilization, multiple specialist consultations, diagnostic tests, CSF diversion procedures, and complications related to CSF diversion surgery.  
 

Population study in Wales

Given that there is a paucity of data regarding the epidemiology, health care utilization, and outcomes of people with IIH, Dr. Pickrell and colleagues conducted the current retrospective cohort study, which aimed to determine the temporal trends of IIH incidence and prevalence in Wales and health care utilization associated with IIH. They also investigated the effects of socioeconomic deprivation and obesity on IIH epidemiology.

For the study, they used and validated primary and secondary care IIH diagnostic codes within the Secure Anonymised Information Linkage data bank, which is part of the national e-health records research infrastructure for Wales, to ascertain IIH cases and controls between 2003 and 2017. In total, 35 million patient-years of data were analyzed. Information was recorded on body mass index, deprivation quintile, CSF diversion surgery, and unscheduled hospital admissions in case and control cohorts.

“This is the first time the diagnostic codes for this condition have been validated. This is important as it is critical if we are studying a condition to know that the individuals we are studying actually have that condition,” Dr. Pickrell commented. “We were able to establish that the diagnostic codes were 92% sensitive and 87% specific – that’s pretty good.”

Results showed a significant increase in IIH incidence and prevalence in Wales. The prevalence of IIH in Wales increased sixfold from 12/100,000 in 2003 to 76/100,000 in 2017, and the incidence of IIH increased threefold from 2.3/100,000 per year in 2003 to 7.8/100,000 per year in 2017. This corresponded with increases in obesity rates: 29% of the population was obese in 2003, compared with 40% in 2017.
 

Reasons for the increase

“The considerable increase in IIH incidence is multifactorial but likely predominately due to rising obesity rates,” the authors noted. “The worldwide prevalence of obesity nearly tripled between 1975 and 2016 and therefore these results also have global relevance.”

The increase in IIH incidence may also be attributable to increased IIH diagnosis rates because of raised awareness of the condition and greater use of digital fundoscopy at routine optometry appointments, they suggested.

“We found a strong association between increasing BMI, sex (being female), and IIH. Around 85% of our IIH cohort were female, similar to other studies, and we also found a significant association with increased deprivation and IIH, particularly in women,” the authors reported.

IIH is associated with increasing deprivation in women even after adjusting for obesity suggesting additional etiologic factors associated with deprivation apart from BMI; this effect was not seen in men, pointing to sex-specific drivers for IIH, they added.

The results also show that individuals with IIH have increased rates of unscheduled health care utilization compared with a matched-control cohort. The rate ratio for unscheduled hospital admissions in the IIH cohort, compared with controls was 5.28.

“A considerable proportion of this excess in unscheduled hospital admissions occurs at the time of diagnosis and can be explained by the need for urgent investigation of papilloedema with brain imaging and spinal fluid analysis. However, there is also a considerable excess in unscheduled hospital admissions up to 2 years after diagnosis,” the authors reported.

They suggested that these admissions are likely to be for severe headache, and they say there is some scope to reduce emergency admissions through better management of headache, patient education, and rapid access to outpatient specialist advice.

They also pointed out that the rate of unscheduled admissions is higher in the IIH cohort in the 3 years leading up to diagnosis, suggesting an opportunity for earlier diagnosis and earlier intervention.

In their study population, 8% of patients with IIH received CSF diversion procedures a mean of 1.3 years after diagnosis, and these patients showed significantly increased unscheduled health care admission rates, compared with IIH patients who had not undergone such procedures.

“There are frequent complications with the shunts after surgery, which causes a high revision rate,” Dr. Pickrell commented. In this study, 40% of patients undergoing CSF diversion needed at least one CSF shunt revision procedure.

The study was supported by the Brain Repair and Intracranial Neurotherapeutics unit, Wales Gene Park, Health Data Research UK, Engineering and Physical Sciences Research Council, Economic and Social Research Council, Department of Health and Social Care (England), Chief Scientist Office of the Scottish Government Health and Social Care Directorates, Health and Social Care Research and Development Division (Wales), Public Health Agency (Northern Ireland), British Heart Foundation, and Wellcome Trust.

The incidence of idiopathic intracranial hypertension (IIH) – characterized by increased cerebrospinal fluid (CSF) pressure – is rising considerably, corresponding to population increases in body mass index (BMI), a new study has shown. “The condition is associated with a high rate of health care utilization, so the increasing incidence has important implications for health care professionals and policy makers in addressing the associated comorbidities,” said senior author William Owen Pickrell, PhD, Swansea University (Wales).

The study was published online Jan. 20 in Neurology.

IIH is a condition of unknown etiology that is strongly associated with obesity, the researchers noted. Predominantly affecting women of childbearing age, it causes chronic disabling headaches, visual disturbance, and in a minority of patients, permanent visual loss. The definitive management is weight loss, but a minority of patients require surgery to preserve vision.

People with IIH potentially have high rates of health care utilization, multiple specialist consultations, diagnostic tests, CSF diversion procedures, and complications related to CSF diversion surgery.  
 

Population study in Wales

Given that there is a paucity of data regarding the epidemiology, health care utilization, and outcomes of people with IIH, Dr. Pickrell and colleagues conducted the current retrospective cohort study, which aimed to determine the temporal trends of IIH incidence and prevalence in Wales and health care utilization associated with IIH. They also investigated the effects of socioeconomic deprivation and obesity on IIH epidemiology.

For the study, they used and validated primary and secondary care IIH diagnostic codes within the Secure Anonymised Information Linkage data bank, which is part of the national e-health records research infrastructure for Wales, to ascertain IIH cases and controls between 2003 and 2017. In total, 35 million patient-years of data were analyzed. Information was recorded on body mass index, deprivation quintile, CSF diversion surgery, and unscheduled hospital admissions in case and control cohorts.

“This is the first time the diagnostic codes for this condition have been validated. This is important as it is critical if we are studying a condition to know that the individuals we are studying actually have that condition,” Dr. Pickrell commented. “We were able to establish that the diagnostic codes were 92% sensitive and 87% specific – that’s pretty good.”

Results showed a significant increase in IIH incidence and prevalence in Wales. The prevalence of IIH in Wales increased sixfold from 12/100,000 in 2003 to 76/100,000 in 2017, and the incidence of IIH increased threefold from 2.3/100,000 per year in 2003 to 7.8/100,000 per year in 2017. This corresponded with increases in obesity rates: 29% of the population was obese in 2003, compared with 40% in 2017.
 

Reasons for the increase

“The considerable increase in IIH incidence is multifactorial but likely predominately due to rising obesity rates,” the authors noted. “The worldwide prevalence of obesity nearly tripled between 1975 and 2016 and therefore these results also have global relevance.”

The increase in IIH incidence may also be attributable to increased IIH diagnosis rates because of raised awareness of the condition and greater use of digital fundoscopy at routine optometry appointments, they suggested.

“We found a strong association between increasing BMI, sex (being female), and IIH. Around 85% of our IIH cohort were female, similar to other studies, and we also found a significant association with increased deprivation and IIH, particularly in women,” the authors reported.

IIH is associated with increasing deprivation in women even after adjusting for obesity suggesting additional etiologic factors associated with deprivation apart from BMI; this effect was not seen in men, pointing to sex-specific drivers for IIH, they added.

The results also show that individuals with IIH have increased rates of unscheduled health care utilization compared with a matched-control cohort. The rate ratio for unscheduled hospital admissions in the IIH cohort, compared with controls was 5.28.

“A considerable proportion of this excess in unscheduled hospital admissions occurs at the time of diagnosis and can be explained by the need for urgent investigation of papilloedema with brain imaging and spinal fluid analysis. However, there is also a considerable excess in unscheduled hospital admissions up to 2 years after diagnosis,” the authors reported.

They suggested that these admissions are likely to be for severe headache, and they say there is some scope to reduce emergency admissions through better management of headache, patient education, and rapid access to outpatient specialist advice.

They also pointed out that the rate of unscheduled admissions is higher in the IIH cohort in the 3 years leading up to diagnosis, suggesting an opportunity for earlier diagnosis and earlier intervention.

In their study population, 8% of patients with IIH received CSF diversion procedures a mean of 1.3 years after diagnosis, and these patients showed significantly increased unscheduled health care admission rates, compared with IIH patients who had not undergone such procedures.

“There are frequent complications with the shunts after surgery, which causes a high revision rate,” Dr. Pickrell commented. In this study, 40% of patients undergoing CSF diversion needed at least one CSF shunt revision procedure.

Women who experienced severe complications during pregnancy were more than twice as likely to die at any time after their last pregnancy, including post partum and beyond, based on data from more than 1 million women.

“Current data suggest that up to 88% of maternal deaths are preceded by severe maternal morbidity,” but the long-term risk of mortality and the effect of severe maternal morbidity has not been well studied, wrote U. Vivian Ukah, MPH, PhD, of McGill University, Montreal, and colleagues.

In a longitudinal cohort study published in Obstetrics & Gynecology, the researchers identified 1,229,306 pregnant women who delivered in Quebec between 1989 and 2016.

The primary outcome of in-hospital mortality after the last pregnancy, either post partum (within 42 days of delivery) or long term (43 days to 29 years after delivery).

Overall, 2.9% of the study population experienced severe maternal morbidity, with an associated mortality rate of 0.86 per 1,000 person-years versus 0.41 per 1,000 person-years in women without severe maternal morbidity. The median time to death for women with severe maternal mortality was 6.8 years, compared with 151 years for those without severe maternal morbidity.

The death rate at any time after delivery, post partum and beyond, was twice as high among women with severe maternal morbidity. The morbidities most often associated with long-term mortality after 42 days were severe cardiac complications (hazard ratio, 7.00), acute renal failure (HR, 4.35), and cerebrovascular accidents (HR, 4.03).

However, the mortality risk following severe maternal morbidity decreased over time, the researchers noted. Severe maternal morbidity was associated with 6.73 times the mortality risk, compared with no morbidity, during the period from 43 days to 11 months, but this difference dropped to 1.91, 1.77, and 1.18 times the risk, compared with no comorbidity, at 1-4 years, 5-9 years, and 10-29 years, respectively.

The study findings were limited by several factors, including the inability to prove causality, the use of only in-hospital mortality data, and the potential for missed cases that fell outside the Canadian Perinatal Surveillance System definition of severe maternal morbidity, the researchers noted.

However, the results suggest that identifying severe maternal morbidity may help identify women at risk for postpartum and long-term premature mortality. “Women with severe maternal morbidity may benefit from continued surveillance and preventative interventions to reduce the risk of premature mortality,” they concluded.

Increased morbidity rates drive need for research

“In this retrospective longitudinal cohort study of over 1.2 million women delivering in Quebec between 1989 and 2016, Dr. Ukah and her colleagues demonstrated the association between severe maternal morbidity [SMM] and an accelerated risk of mortality beyond the postpartum period, compared with women who do not experience SMM,” Rachel Humphrey, MD, a maternal-fetal medicine specialist at Advent Health in Orlando, said in an interview. “This study is important as there has been a steady increase in SMM in recent years. In the United States, the CDC reports that SMM affected more than 50,000 women in 2014 alone. Across multiple countries the decline in overall health of women giving birth is felt to contribute to SMM. As the rates of preexisting conditions such as maternal obesity, hypertension, diabetes, and advanced age increases, we can assume that SMM will increase as well. This study clearly depicts the association between SMM and maternal death at 43 days to years after the complicated delivery. We can assume that, as SMM increases, so will the risk of mortality beyond the postpartum period for these women who initially survive their serious pregnancy complication.”

Dr. Humphrey said that, in some respects, the study results are to be expected. “It is logical to assume that a patient with a life-threatening issue at delivery such as severe cardiac complications, acute renal failure and cerebrovascular accident would be at higher risk for long-term morbidity and mortality. This study also adds to the large body of evidence linking socioeconomic deprivation with SMM. But there were unexpected findings in this study. I did not expect certain types of SMM to be associated with an increased risk of death years after the event.For example, hysterectomy at delivery carried a hazard ratio of 3.54 for death at 5-9 years after the event. The association between severe hemorrhage and fully adjusted hazard ratio was similarly increased at 2.96 [2.37-3.71].”

 

More screening and prospective studies needed

“Recognizing the association between SMM and accelerated long-term risk of mortality is a first step in determining what interventions might improve health and longevity in women who experience SMM,” said Dr. Humphrey. “With the absence of prospective studies, it still is logical to assume that close medical follow-up and lifestyle interventions are appropriate in this population. Screening for and actively managing chronic conditions such as diabetes, dyslipidemia, and hypertension seems appropriate for these patients.”

As for further research, “I am interested to know through prospective clinical trials if specific health maintenance screens and interventions would have a positive impact on the life expectancy of survivors of SMM,” said Dr. Humphrey. “I applaud this team for providing data up to 27 years after an obstetric complication, and I am interested to see if Dr. Ukah and her team will continue their research to determine if there is a ‘second peak’ in mortality in the survivors of SMM when they are elderly. Finally, I would be interested to see more detailed data from this team on the associations between socioeconomic deprivation and short- and long-term mortality for women in their study. This information may help further fuel the movement toward social changes to maximize the health of the women and families we serve.”

The study was supported by the Heart & Stroke Foundation of Canada and awards to the lead author and others from the Fonds de recherche du Québec-Santé. The researchers and Dr. Humphrey had no financial conflicts to disclose.

While many people were committing to their New Year’s resolutions to lose weight, in January 2020 Cosmopolitan UK magazine released covers portraying 11 women of different shapes and sizes, with the headline, “This is healthy!” Each version of the cover features one or more of the 11 women wearing athletic gear and makeup, some of whom are caught mid-action – boxing, doing yoga, or simply rejoicing in being who they are. Seeing these, I was reminded of a patient I cared for as an intern.

Janet Spears (not her real name) was thin. Standing barely 5 feet 3 inches, she weighed 110 pounds. For those out there who think of size in terms of body mass index (BMI), it was about 20 kg/m², solidly in the “normal” category. At the age of 62, despite this healthy BMI, she had so much plaque in her arteries that she needed surgery to improve blood flow to her foot.

Admittedly, whenever I had read about people with high cholesterol, type 2 diabetes, or atherosclerosis, I pictured bigger people. But when I met Ms. Spears, I realized that one’s health cannot necessarily be inferred from physical appearance.

As a bariatric surgeon board certified in obesity medicine, I’ve probably spent more time thinking and learning about obesity than most people – and yet I still didn’t know what to make of the Cosmopolitan covers.

I saw the reaction on Twitter before I saw the magazines themselves, and I quickly observed a number of people decrying the covers, suggesting that they promote obesity:

Multiple people suggested that this was inappropriate, especially in the context of the COVID-19 pandemic and the fact that people with obesity are at risk for worse outcomes, compared with those without obesity. (As an aside, these comments suggest that people did not read the associated article, which is about fitness and body image more than it is about obesity.)
 

Does size reflect health?

Putting the pandemic aside for a moment, the question the magazine covers raise is whether physical appearance reflects health. That’s what got me thinking about Ms. Spears, who, though appearing healthy, was sick enough that she needed to have major surgery. This whole conversation hinges, of course, on one’s definition of health.

A common knee-jerk response, especially from physicians, would be to say that obesity is by definition unhealthy. Some researchers have suggested though that a segment of people with obesity fall into a category called metabolically healthy obesity, which is typically characterized by a limited set of data such as cholesterol, blood sugar, and blood pressure. Indeed, some people with obesity have normal values in those categories.

Being metabolically healthy, however, does not preclude other medical problems associated with obesity, including joint pain, cancer, and mood disorders, among other issues. So even those who have metabolically healthy obesity are not necessarily immune to the many other obesity-related conditions.
 

What about body positivity?

As I delved further into the conversation about these covers, I saw people embracing the idea of promoting different-sized bodies. With almost two thirds of the U.S. population having overweight or obesity, one might argue that it’s high time magazine covers and the media reflect the reality in our hometowns. Unrealistic images in the media are associated with negative self-image and disordered eating, so perhaps embracing the shapes of real people may help us all have healthier attitudes toward our bodies.

That said, this idea can be taken too far. The Health at Every Size movement, which some might consider to be the ultimate body-positivity movement, espouses the idea that size and health are completely unrelated. That crosses a line between what we know to be true – that, at a population level, higher weight is associated with more medical problems – and fake news.

Another idea to consider is fitness, as opposed to health. Fitness can be defined multiple ways, but if we consider it to be measured exercise capacity, those who are more fit have a longer life expectancy than those with lower fitness levels at a given BMI. While some feel that the Cosmopolitan covers promote obesity and are therefore irresponsible, it’s at least as likely that highlighting people with obesity being active may inspire others with obesity to do the same.

Now let’s bring the pandemic back into the picture. As much as we all wish that it was over, with uncontrolled spread in every state and record numbers of people dying, COVID-19 is still very much a part of our reality. Having obesity increases the risk of having a severe case of COVID-19 if infected. Patients with obesity are also more likely than those without obesity to be hospitalized, require intensive care, and die with COVID-19.
 

Guiding the conversation

Pandemic or not, the truth is that obesity is related to multiple medical problems. That does not mean that every person with obesity has medical problems. The musician Lizzo, for example, is someone with obesity who considers herself to be healthy. She posts images and videos of working out and shares her personal fitness routine with her millions of fans. As a physician, I worry about the medical conditions – metabolic or otherwise – that someone like her may develop. But I love how she embraces who she is while striving to be healthier.

Most of the critical comments I have seen about the Cosmopolitan covers have, at best, bordered on fat shaming; others are solidly in that category. And the vitriol aimed at the larger models is despicable. It seems that conversations about obesity often vacillate from one extreme (fat shaming) to the other (extreme body positivity).

Although it may not sell magazines, I would love to see more nuanced, fact-based discussions, both in the media and in our clinics. We can start by acknowledging the fact that people of different sizes can be healthy. The truth is that we can’t tell very much about a person’s health from their outward appearance, and we should probably stop trying to make such inferences.

Assessment of health is most accurately judged by each person with their medical team, not by observers who use media images as part of their own propaganda machine, pushing one extreme view or another. As physicians, we have the opportunity and the responsibility to support our patients in the pursuit of health, without shame or judgment. Maybe that’s a New Year’s resolution worth committing to.

We can start by acknowledging the fact that people of different sizes can be healthy. The truth is that we can’t tell very much about a person’s health from their outward appearance, and we should probably stop trying to make such inferences.

Assessment of health is most accurately judged by each person with their medical team, not by observers who use media images as part of their own propaganda machine, pushing one extreme view or another. As physicians, we have the opportunity and the responsibility to support our patients in the pursuit of health, without shame or judgment. Maybe that’s a New Year’s resolution worth committing to.

While many people were committing to their New Year’s resolutions to lose weight, in January 2020 Cosmopolitan UK magazine released covers portraying 11 women of different shapes and sizes, with the headline, “This is healthy!” Each version of the cover features one or more of the 11 women wearing athletic gear and makeup, some of whom are caught mid-action – boxing, doing yoga, or simply rejoicing in being who they are. Seeing these, I was reminded of a patient I cared for as an intern.

Janet Spears (not her real name) was thin. Standing barely 5 feet 3 inches, she weighed 110 pounds. For those out there who think of size in terms of body mass index (BMI), it was about 20 kg/m², solidly in the “normal” category. At the age of 62, despite this healthy BMI, she had so much plaque in her arteries that she needed surgery to improve blood flow to her foot.

Admittedly, whenever I had read about people with high cholesterol, type 2 diabetes, or atherosclerosis, I pictured bigger people. But when I met Ms. Spears, I realized that one’s health cannot necessarily be inferred from physical appearance.

As a bariatric surgeon board certified in obesity medicine, I’ve probably spent more time thinking and learning about obesity than most people – and yet I still didn’t know what to make of the Cosmopolitan covers.

I saw the reaction on Twitter before I saw the magazines themselves, and I quickly observed a number of people decrying the covers, suggesting that they promote obesity:

Multiple people suggested that this was inappropriate, especially in the context of the COVID-19 pandemic and the fact that people with obesity are at risk for worse outcomes, compared with those without obesity. (As an aside, these comments suggest that people did not read the associated article, which is about fitness and body image more than it is about obesity.)
 

Does size reflect health?

Putting the pandemic aside for a moment, the question the magazine covers raise is whether physical appearance reflects health. That’s what got me thinking about Ms. Spears, who, though appearing healthy, was sick enough that she needed to have major surgery. This whole conversation hinges, of course, on one’s definition of health.

A common knee-jerk response, especially from physicians, would be to say that obesity is by definition unhealthy. Some researchers have suggested though that a segment of people with obesity fall into a category called metabolically healthy obesity, which is typically characterized by a limited set of data such as cholesterol, blood sugar, and blood pressure. Indeed, some people with obesity have normal values in those categories.

Being metabolically healthy, however, does not preclude other medical problems associated with obesity, including joint pain, cancer, and mood disorders, among other issues. So even those who have metabolically healthy obesity are not necessarily immune to the many other obesity-related conditions.
 

What about body positivity?

As I delved further into the conversation about these covers, I saw people embracing the idea of promoting different-sized bodies. With almost two thirds of the U.S. population having overweight or obesity, one might argue that it’s high time magazine covers and the media reflect the reality in our hometowns. Unrealistic images in the media are associated with negative self-image and disordered eating, so perhaps embracing the shapes of real people may help us all have healthier attitudes toward our bodies.

That said, this idea can be taken too far. The Health at Every Size movement, which some might consider to be the ultimate body-positivity movement, espouses the idea that size and health are completely unrelated. That crosses a line between what we know to be true – that, at a population level, higher weight is associated with more medical problems – and fake news.

Another idea to consider is fitness, as opposed to health. Fitness can be defined multiple ways, but if we consider it to be measured exercise capacity, those who are more fit have a longer life expectancy than those with lower fitness levels at a given BMI. While some feel that the Cosmopolitan covers promote obesity and are therefore irresponsible, it’s at least as likely that highlighting people with obesity being active may inspire others with obesity to do the same.

Now let’s bring the pandemic back into the picture. As much as we all wish that it was over, with uncontrolled spread in every state and record numbers of people dying, COVID-19 is still very much a part of our reality. Having obesity increases the risk of having a severe case of COVID-19 if infected. Patients with obesity are also more likely than those without obesity to be hospitalized, require intensive care, and die with COVID-19.
 

Guiding the conversation

Pandemic or not, the truth is that obesity is related to multiple medical problems. That does not mean that every person with obesity has medical problems. The musician Lizzo, for example, is someone with obesity who considers herself to be healthy. She posts images and videos of working out and shares her personal fitness routine with her millions of fans. As a physician, I worry about the medical conditions – metabolic or otherwise – that someone like her may develop. But I love how she embraces who she is while striving to be healthier.

Most of the critical comments I have seen about the Cosmopolitan covers have, at best, bordered on fat shaming; others are solidly in that category. And the vitriol aimed at the larger models is despicable. It seems that conversations about obesity often vacillate from one extreme (fat shaming) to the other (extreme body positivity).

Although it may not sell magazines, I would love to see more nuanced, fact-based discussions, both in the media and in our clinics. We can start by acknowledging the fact that people of different sizes can be healthy. The truth is that we can’t tell very much about a person’s health from their outward appearance, and we should probably stop trying to make such inferences.

In a phase 2 randomized clinical trial of adults with type 2 diabetes and obesity, investigational drug bimagrumab (BYM338, Novartis) – a monoclonal antibody that blocks activin type II receptors and stimulates skeletal muscle growth – led to big reductions in total body fat mass and A1c and significant increases in lean mass compared with placebo.

The efficacy and safety findings “suggest that blockade of the activin receptor with bimagrumab could provide a novel pharmacologic approach for managing patients with type 2 diabetes with excess adiposity,” Steven B. Heymsfield, MD, Pennington Biomedical Research Center, Louisiana State University System, Baton Rouge, and colleagues reported in their study, published online Jan. 13 in JAMA Network Open. 

Preliminary findings from the study of 75 patients treated for 48 weeks – in which neither group ate less despite intensive nutrition advice – were presented at Obesity Week in 2019.

As reported then, Lee M. Kaplan, MD, PhD, noted that the 6.5% weight loss in the bimagrumab group was similar to that seen with antiobesity medications that suppress appetite.

“What it suggests,” he said in an interview, “is that there may be a completely new mechanism at play here,” because patients receiving bimagrumab weren’t eating less but were losing the same amount of weight as reported for weight-loss drugs that work by decreasing appetite.

“Is this going to be the kind of complementary drug with a different mechanism that’s going to augment the effects of other drugs?” wondered Dr. Kaplan, director of the Obesity, Metabolism & Nutrition Institute at Massachusetts General Hospital, Boston, who has previously served as a scientific consultant to Novartis.

Asked about future plans for bimagrumab, a Novartis spokesperson said in an interview, “We are currently reviewing the program strategy and considering next steps.”
 

Four FDA-approved weight-loss drugs now approved

The Food and Drug Administration approval for lorcaserin (Belviq, Belviq XR, Eisai) for weight loss was rescinded on Feb. 13, 2020, when a postmarketing trial revealed an increased occurrence of cancer, leaving four drugs approved for weight loss in the United States, plus several drugs in development, Dr. Heymsfield and colleagues wrote.

The current phase 2 trial was designed to determine the safety and efficacy of bimagrumab – which had originally been studied to see if it would increase lean muscle mass in people with sarcopenia – on total body fat mass and glycemic control in patients with type 2 diabetes and overweight or obesity.

Researchers enrolled 75 adults at eight sites in the United States and one in Wales, United Kingdom, from 2017 to 2019.

On average, patients were 60 years old with an A1c of 7.8% and a body mass index of 32.9 kg/m²; they weighed 93.6 kg and had a fat mass of 35 kg.

Patients received an intravenous infusion of bimagrumab (10 mg/kg up to 1,200 mg in 5% dextrose solution) or placebo (5% dextrose solution) every 4 weeks for 48 weeks. They met with a registered dietitian at each monthly study visit and had a virtual check-in between visits.

Participants were advised to follow a diet that would cut 500 calories a day and encouraged to follow the American Diabetes Association walking program.

Body fat mass was measured by dual-energy x-ray absorptiometry (DEXA).

There were more women in the bimagrumab group than in the placebo group (62% vs. 32%), but baseline BMI, total body fat mass, and A1c were similar in both groups.
 

Same caloric intake, less fat tissue, more muscle, smaller waist

At 48 weeks in the bimagrumab vs. placebo group, there was on average (all P < .001):

• A loss of 20.5% vs. 0.5% (−7.5 vs. −0.2 kg) of total body fat mass.
• A loss of 6.5% vs. 0.8% (−5.9 vs. −0.8 kg) of body weight.  
• A gain of 3.6% vs. a loss of 0.8% (1.7 vs. −0.4 kg) of lean mass.

Similarly, the relatively large between-group differences in total body fat mass and body weight at 48 weeks with bimagrumab were accompanied by favorable differences in BMI (−2.19 vs. −0.28 kg/m²; P < .001) and waist circumference (−9.0 vs. 0.5 cm; P < .001), the investigators pointed out.

Moreover, the reduction of abdominal visceral adipose tissue and waist circumference with bimagrumab “was nearly twice that observed in a recently published study of patients with type 2 diabetes treated with an intensive lifestyle program and the glucagon-like peptide 1 (GLP-1) agonist liraglutide,” they noted.

This highlights “the importance of moving away from body weight as a primary efficacy marker of drugs to more metabolically relevant endpoints.”

Also, A1c decreased by 0.76% in the bimagrumab group and increased by 0.04% in the placebo group (P = .005).

Serious adverse events occurred in three patients (8%) in the bimagrumab group (elevated lipase, epigastric pain, pancreatitis, pneumonia) and three patients (8%) in the placebo group (cellulitis, acute coronary syndrome, acute myocardial infarction, worsening gastroparesis, thermal burn).  

Adverse events were reported by 31 of 37 patients in the bimagrumab group, most often mild diarrhea (41%) and muscle spasms (41%), and 31 of 38 patients in the placebo group, most often headache (13%) and upper respiratory tract infection (13%).

The study was funded by Novartis. Dr. Heymsfield has reported receiving personal fees from Tanita and Medifast outside the submitted work. Disclosures for the other authors are listed in the article. Dr. Kaplan has reported previously serving as a scientific consultant to Novartis.
