Having specific health issues, including depressive symptoms and cardiovascular disease, as a middle-aged woman was associated with experiencing clinically important declines in health later in life, a new study finds.

The most predictive parameters of poorer health at age 65 were cardiovascular disease, clinically significant depressive symptoms, and current smoking. Osteoarthritis, lower education level, and higher body mass index (BMI) also were associated with poorer health status 10 years on, Daniel H. Solomon, MD, MPH and colleagues wrote in their observational study, which was published in JAMA Network Open.

Determining a patient’s score on a health-related quality of life measure based on these variables might be useful in clinical practice to recognize midlife patients at increased risk for later health deterioration, Dr. Solomon, of the division of rheumatology, inflammation, and immunity at Brigham and Women’s Hospital, Boston, said in a statement. This measure is called the Short Form 36 (SF-36), and the researchers specifically focused on the physical component summary score (PCS) of this measure. The SF-36 is similar to the Framingham 10-year coronary heart disease risk prediction score, according to Dr. Solomon, who is a professor of medicine at Harvard Medical School, also in Boston.

Based on their risk scores, women could preemptively target modifiable risk factors before they enter old age, the investigators wrote.

“Age 55-65 may be a critical decade. A person’s health and factors during this period may set them on a path for their later adult years,” Dr. Solomon said in a statement. “The good news is that a large proportion of women at midlife are very stable and will not go on to experience declines. But being able to identify women at higher risk could help lead to interventions targeted to them.”
 

Study details

The study included a cohort of 1,091 women drawn from the 3,302-participant Study of Women’s Health Across the Nation (SWAN), a racially and ethnically diverse group enrolled from six U.S. sites at or immediately before transition to menopause and followed for 10 years from age 55 to 65. The study sample, consisting of 24.6% Black, 24% Japanese or Chinese, and 51.9% White, had a median baseline age of 54.8 years and median BMI of 27 kg/m² at entry. The median baseline PCS score was 53.1 (interquartile range, 46.8-56.7).

Over 10 years, 206 (18.9%) of the women in the study experienced clinically important declines of at least 8 points in baseline characteristics at around age 55. The following were significantly associated with these declines:

• Having a higher BMI.
• Having osteoarthritis.
• Having a lower educational level.
• Being a current smoker.
• Having clinically significant depressive symptoms.
• Having cardiovascular disease.
• Having better (or higher) physical health and function score on the PCS.

The association between a higher PCS score and a greater decline might seem like an anomaly, Dr. Solomon said in an interview, but one interpretation of this finding is that women with higher or better scores at baseline have further to fall once other risk factors take effect.

With data analyzed from October 2020 to March 2021, the median 10-year change in PCS was –1.02 points, but 206 women experienced declines of 8 points or more.

Those with health declines were more likely to be Black and less likely to be Japanese. They were also more likely to have other comorbidities such as diabetes, hypertension, and osteoporosis, and to report less physical activity.
 

Scoring system should not replace individualized evaluation, outside expert said

Commenting on the findings, Margaret J. Nachtigall, MD, a clinical associate professor in the department of obstetrics and gynecology at New York University Langone Health, cautioned that a generalized scoring system should not replace individualized evaluation of women at midlife.

“I assess women around age 55 on a daily basis for health risk factors going forward. And while a number such as BMI can be helpful, I worry that reliance on a score could miss treating the individual,” Dr. Nachtigall said an interview. For instance, one woman might have a high BMI owing to greater muscle mass, which is heavy, while another may have a lower BMI but more fat-related weight, as well as exacerbating conditions such as hypertension that would elevate her risk. “You have to make the calculation for each person.”

Dr. Nachtigall, who was not involved in the SWAN analysis, noted, however, that a big-data scoring system might be a useful adjunct to individual patient evaluation in that “it would make physicians look at all these many risk factors to identify those prone to decline.”
 

Study includes racially diverse population

According to the authors, while other studies have identified similar and other risk factors such as poor sleep, most have not included such a racially diverse population and have focused on women already in their senior years when the window of opportunity may already have closed.

“As a clinician and epidemiologist, I often think about the window of opportunity at midlife, when people are vital, engaged, and resilient,” said Dr. Solomon in the statement. “If we can identify risk factors and determine who is at risk, we may be able to find interventions that can stave off health declines and help put people on a better health trajectory.”

Eric M. Ascher, DO, who practices family medicine at Lenox Hill Hospital in New York and was not involved in the SWAN research, agreed with Dr. Solomon.

“Doctors who treat chronic conditions often meet patients when they are already suffering from a medical problem,” he said in an interview. “It is key to decrease your risk factors before it is too late.”

Dr. Ascher added that many primary care providers already rely heavily on scoring systems when determining level of risk and type of intervention. “Any additional risk factor-scoring systems that are easy to implement and will prevent chronic diseases would be something providers would want to use with their patients.”

Detailed analyses of larger at-risk populations are needed to validate these risk factors and identify others, the authors said.

SWAN is supported by the National Institute on Aging, the National Institute of Nursing Research, and the National Institutes of Heath’s Office of Research on Women’s Health. Dr. Solomon reported financial ties to Amgen, AbbVie and Moderna, UpToDate, and Arthritis & Rheumatology; as well as serving on the board of directors for the Childhood Arthritis and Rheumatology Research Alliance and an advisory committee for the Food and Drug Administration outside of this work. Dr. Nachtigall and Dr. Ascher disclosed no conflicts of interest with regard to their comments.

Severe maternal sleep-disordered breathing (SDB) is a known risk factor for gestational diabetes, which is commonly diagnosed in the second or third trimester of pregnancy.

Now, a new study suggests that increases in insulin resistance, a precursor for gestational diabetes, may take place as early as the first trimester of pregnancy in women with risk factors for obstructive sleep apnea (OSA), such as overweight and habitual snoring.

This finding could potentially provide physicians with a window of opportunity to improve outcomes by screening at-risk women early in pregnancy or even prior to conception, Laura Sanapo, MD, assistant professor of medicine (research) at Brown University, Providence, R.I., and colleagues wrote in Sleep.

“Further studies are needed to investigate the association and its impact on the development of gestational diabetes, and to establish whether early-gestation or pregestational treatment of SDB would improve glucose metabolic outcomes in pregnancy,” they wrote.

”What this paper demonstrates is that the changes that predate gestational diabetes are seen much earlier in pregnancy,” senior study author Ghada Bourjeily, MD, professor of medicine at Brown University, said in an interview. Women should be screened for SDB rather than insulin resistance in early pregnancy since continuous positive airway pressure therapy (CPAP) is a highly effective intervention.

Waiting until midpregnancy to screen for OSA “is too late to make significant changes in the care of these women,” said Dr. Bourjeily, who is also director of research and training at the Women’s Medicine Collaborative at The Miriam Hospital in Providence, R.I. “By the time you diagnose gestational diabetes, the cat is out of the bag.”

For the study, women with early singleton pregnancies and risk factors for OSA such as habitual snoring and a median body mass index (BMI) of at least 27 kg/m² were recruited from two prospective clinical trial studies enriched for OSA positivity. Women with a history of pregestational diabetes and those using CPAP or receiving chronic steroid therapy were excluded from the current study.

A total of 192 study participants underwent in-home sleep study (HSAT) and homeostatic model assessment (HOMA) between 11 and 15 gestational weeks, respectively. The association between continuous measures of SDB as a respiratory-event index as well as oxygen-desaturation index and glucose metabolism parameters such as insulin resistance (HOMA-IR) were analyzed after adjusting for gestational age, maternal age, BMI, ethnicity, race, and parity.

In all, 61 women (32%) were diagnosed with OSA based on respiratory event index values greater than or equal to five events per hour. These participants were more likely to be older, to have a high BMI, and to be multipara, compared with women who didn’t have a diagnosis of OSA. Women with a diagnosis of OSA exhibited higher glucose and C-peptide values and a higher degree of insulin resistance, compared with women without OSA, the researchers found. An increase of 0.3 in HOMA-IR related to maternal SDB in early pregnancy may significantly affect glucose metabolism.

Although the findings of the current study cannot be extrapolated to women who don’t have overweight or obesity, some women with normal-range BMI (18.5-24.9) are also at increased risk of glucose metabolism changes, Dr. Bourjeily pointed out. This includes those of Southeast Asian descent. “We found that the association of SDB parameters with insulin resistance was actually happening independently of BMI and other factors.”

Ideally, screening for SDB would begin prior to pregnancy, Dr. Bourjeily said. A BMI greater than 25 should be taken into account and patients asked if they snore and if so, whether it’s loud enough to wake their partner. They should also be asked about experiencing daytime sleepiness.

“Based on these answers, especially in women screened prior to pregnancy, there will be time to make the diagnosis of sleep apnea and get the patient on CPAP,” Dr. Bourjeily said.

“This is an interesting study and one of the rare ones looking at early pregnancy and some of the mechanisms that could possibly be contributing to gestational diabetes,” commented Grenye O’Malley, MD, assistant professor in the division of endocrinology, diabetes, and bone disease at the Icahn School of Medicine at Mount Sinai, New York. Dr. O’Malley was not involved in the study.

“It confirms our suspicions that there’s probably a lot of things happening earlier in pregnancy before a diagnosis of gestational diabetes. It also confirms that some of the mechanisms are probably very similar to those involved in the association between disordered sleep and the development of type 2 diabetes.”

However, it’s too early to determine whether screening for SDB and the use of CPAP will prevent glycemic changes, Dr. O’Malley said in an interview. “Whenever we screen, we ask whether we have an intervention that changes outcomes and we don’t know that yet.”

Some of the symptoms of SDB are also common in early pregnancy, such as a BMI greater than 25 and daytime sleepiness, Dr. O’Malley pointed out. It was unclear whether the study participants had a propensity to develop type 2 diabetes or whether they were at risk of gestational diabetes.

This study was funded by the National Heart, Lung, and Blood Institute; the National Institute for Child Health; and the National Institute of General Medical Sciences. Dr. Bourjeily and colleagues, as well as Dr. O’Malley, reported having no potential financial conflicts of interest.

A new document from the American Heart Association summarizes the latest research on cardiovascular risk factor management in type 2 diabetes, including medications, lifestyle, and social determinants of health.

Despite the availability of effective therapies for improving cardiovascular risk, in the United States fewer than one in five people with type 2 diabetes and without known cardiovascular disease meet control targets for a combination of A1c, blood pressure, LDL cholesterol, and nonsmoking status.

That proportion drops to less than 1 in 10 if body mass index less than 30 kg/m² is included among the targets, and even less than that among individuals with established atherosclerotic cardiovascular disease, Joshua J. Joseph, MD, and colleagues point out in their paper, published online Jan. 10 in Circulation.

“This new scientific statement is an urgent call to action to follow the latest evidence-based approaches and to develop new best practices to advance type 2 diabetes treatment and care and reduce cardiovascular disease risk,” wrote Dr. Joseph, assistant professor of medicine in the division of endocrinology, diabetes, and metabolism at The Ohio State University, Columbus, Ohio, and coauthors.

The statement is not a guideline but an expert analysis that may inform future clinical practice guidelines, according to a press release from the AHA.

The new statement reviews evidence through June 2020 for lifestyle management of diabetes and weight, glycemic targets and control, blood pressure management, lipid management, antithrombotic therapy, and screening for cardiovascular and renal complications, including imaging. It also discusses the clinical implications of recent cardiovascular outcomes trials of newer glucose-lowering medications.

However, Dr. Joseph and colleagues point out, clinical care and treatment account for just 10%-20% of modifiable contributors to health outcomes. The other 80%-90% relate to social determinants of health, including health-related behaviors, socioeconomic factors, environmental factors, and racism.

“If we are to continue to advance the management of cardiovascular risk factors, we must also address the [social determinants of health] in the delivery of health care,” they noted.

Overall, they advise a patient-centered approach, meaning “reframing our clinical encounters to think about patients as people who live in families, communities, and societies that must be considered in their cardiovascular risk management.”

“People with [type 2 diabetes] face numerous barriers to health including access to care and equitable care, which must be considered when developing individualized care plans with our patients,” Dr. Joseph said in the AHA press release.
 

Lifestyle, medications for lowering A1c, BP, lipids

For lifestyle management, the authors say, “culturally appropriate recommendations through diabetes self-management education and support and medical nutrition therapy are key to meeting individualized goals for behavioral change and diabetes self-management.”

The document summarizes recommendations from other professional societies regarding glycemic targets and glucose lowering medications, i.e., target A1c levels of either < 7% or < 6.5% for the majority, with adjustments based on individual factors, such as life expectancy. It advises on use of metformin as first-line therapy followed by a sodium-glucose cotransporter-2 inhibitor or a glucagon-like peptide-1 agonist for those with established cardiovascular disease or risk factors.

“Cost may be a barrier to taking some [type 2 diabetes] medications as prescribed; however, many of these medications are now more commonly covered by more health insurance plans,” Dr. Joseph said.

“Another barrier is recognition by patients that these newer [type 2 diabetes] medications are also effective in reducing the risk of heart disease, stroke, heart failure, and kidney disease.”

Blood pressure treatment guidelines differ between those of the AHA/American College of Cardiology (ACC) and the American Diabetes Association (ADA), most notably that the AHA/ACC guidelines advise a general target of < 130/80 mm Hg, whereas ADA advises < 140/90 mm Hg or < 130/80 mm Hg for those with high risk if it can be safely achieved.

The decision should be “patient-centered with shared decision-making,” Dr. Joseph and colleagues advised.

For lipid-lowering, the document cites the 2018 ACC/AHA cholesterol guidelines, which include advising statins as first-line therapy for both primary and secondary prevention in diabetes, with highest intensity statins used in those at highest risk. But again, treatment should be individualized, and other agents should be used for patients in whom statins don’t work or aren’t tolerated.

And while use of antiplatelets – that is, aspirin – is well established as secondary prevention in type 2 diabetes, given new data suggesting that the risk for major bleeding could outweigh the benefits for primary prevention, “the relative benefits of antithrombotic approaches need to be weighed carefully against risks using a patient-centered approach,” the authors advised.

Among the many imaging tests available to facilitate cardiovascular risk stratification in type 2 diabetes, coronary artery calcification (CAC) CT screening is one of the few with sufficient data to support routine use in selected patients. The National Lipid Association, for example, recommends escalation to high-intensity statin for CAC > 100.

“One avenue to continue to address and advance diabetes management is through breaking down the four walls of the clinic or hospital through community engagement, clinic-to-community connections, and academic-community-government partnerships that may help address and support modifiable lifestyle behaviors such as physical activity, nutrition, smoking cessation and stress management,” Dr. Joseph concluded.

The AHA receives funding primarily from individuals. Foundations and corporations, including pharmaceutical, device manufacturers, and other companies, also make donations and fund AHA programs and events. The AHA’s strict policies prevent these relationships from influencing the science content. Revenues from pharmaceutical and biotech companies, device manufacturers, and health insurance providers and the AHA’s financial information are available on the association’s website. Dr. Joseph has disclosed no relevant financial relationships.

An obesity prevention program targeted at parents of infants benefited not only firstborn infants but their second-born siblings as well, a new study suggests.

According to a statement from the National Institutes of Health, who funded the study, it is the first such infant obesity intervention to show the spillover effect. Findings were published online Dec. 21, 2021, in Obesity.

The program is called Infants Growing on Healthy Trajectories (INSIGHT) responsive parenting (RP) intervention, and it included guidance on feeding, sleep, interactive play, and regulating emotion.

Parents were given guidance by nurses who came to their homes on how to respond when their child is drowsy, sleeping, fussy, and alert. They also learned how to put infants to bed drowsy, but awake, and avoid feeding infants to get them to sleep; how to respond to infants waking up at night; when to start solid foods; how to limit inactive time; and how to use growth charts.

The control group program focused on safety and matched the guidance categories. For example, early visits included information on prevention of sudden infant death syndrome for sleep, breast milk storage and formula for feeding, and safe bathing.

Jennifer S. Savage, Center for Childhood Obesity Research, Penn State University, University Park, led the study that enrolled 117 infants in a randomized controlled trial. Mother and firstborn children were randomized to the RP or home safety intervention (control) group 10-14 days after delivery. Their second-born siblings were enrolled in an observation-only ancillary study.

Second-born children were delivered 2.5 (standard deviation, 0.9) years after firstborns. Anthropometrics were measured in both siblings at ages 3, 16, 28, and 52 weeks.

Firstborn children at 1 year had a body mass index (BMI) that was 0.44 kg/m² lower than the control group (95% confidence interval, −0.82 to −0.06), and second-born children whose parents received the RP intervention with their first child had BMI that was 0.36 kg/m² lower.

“What we saw here is that it worked again,” coauthor Ian Paul, MD, MSc, professor of pediatrics and public health sciences at Penn State University, Hershey, said in an interview.

“Once we imprint them with a certain approach to parenting with the first child, they’re doing the same thing with the second child, which is wonderful to see,” he said.

He noted that this happened with second children without any reinforcements or booster information.

Dr. Paul said it’s still not clear which of the interventions – whether related to feeding techniques or sleeping or activity – helps most. And for each family the problematic behaviors may be different.

Responsive parenting programs have shown success previously among firstborns, the authors wrote, but 80% of those children grow up with younger siblings, so an intervention that also benefits them is important.

Weighing the costs of the intervention

The intervention was extensive. It involved four hour-plus nurse visits a year, often by the same nurse who built a relationship with the family.

But Ms. Savage said that it is possible to replicate INSIGHT on a larger scale in the United States with the dozens of home visitation models.

“Currently, 21 home visitation models meet the U.S. Department of Health & Human Services criteria for evidence of effectiveness, such as Nurse Family Partnership, Family Check-up, and Early Head Start Home Based Option. There is an opportunity to use home visitation models at the national scale to potentially interrupt the cycle of poor multigenerational outcomes such as obesity,” she said.

Dr. Paul said the initial investment “can save money in the long term,” given what’s at stake. “We know that 20%-25% of 2- to 5-year-olds are already overweight or obese and if they are already overweight or obese at that age, that;’s likely to persist.”

However, he acknowledged that staff shortages and costs are a challenge.

“Other countries have made that investment in their health care system,” he said. “In the U.S. only a fraction of new mothers and babies get home visitation. The kind of work that we did for obesity prevention has not yet been incorporated into evidence-based models of home visitation, though it certainly could be.”

Dr. Paul said his team is hoping to collaborate with others in the near future on expanding this program to such models of home visitation.

Telehealth, though a less desirable option, compared with in-home visits, could also be utilized, he said.

Short of the comprehensive intervention, he said, many of the concepts can be put into practice by pediatricians and parents.

Dr. Paul noted that the Robert Wood Johnson Foundation has endorsed “responsive feeding” as the preferred approach to feeding infants and toddlers. Responsive feeding – helping parents recognize hunger and satiety cues as opposed to other distress cues – is a big part of the intervention.

“Feeding to soothe is not the preferred approach,” he said. “Food and milk and formula should be used for hunger.” That’s something pediatricians may not be stressing to parents, he said.

Pediatricians can also counsel parents on not using food as a reward. “We shouldn’t be giving kids M&Ms to teach them how to potty train,” he said.
 

‘Promising’ findings

Charles Wood, MD, a childhood obesity specialist at Duke University, Durham, N.C., who was not part of the study, called the findings “very promising.”

It also makes sense that the “aha moments” of first-time parents learning from the INSIGHT intervention would carry over to the second sibling, he said.

Dr. Wood agreed costs are a big factor. However, he said, the potential downstream costs of not preventing obesity are worse. And this study indicates the benefits may keep spreading with future siblings.

Dr. Wood said accessing obesity interventions outside the pediatrician visit can also help. Connecting patients with support groups or dietitians or with a counselor from Women, Infants, and Children can help. However, consistent messaging among the providers is key, he noted.

Dr. Wood’s research group is investigating text messaging platforms so parents can get answer to real-time questions, such as those about feeding behaviors.

He pointed to a limitation the authors mention, which is that the study was done in mostly White, highly educated, higher-income families.

“There’s a big problem with racial disparities and obesity,” Dr. Wood noted. “We definitely need solutions that address disparities as well.”

Mothers included in the study had given birth for the first time and their infants were enrolled after birth from a single maternity ward between January 2012 and March 2014. Major eligibility criteria were that the babies were full term (at least 37 weeks’ gestation), single births, and delivered to English-speaking mothers at least 20 years of age. Infants who weighed less than 2,500 g at birth were excluded.

The paper’s authors and Dr. Wood declared no relevant financial relationships.

This research was supported by the National Institutes of Health, the National Institute of Diabetes and Digestive and Kidney Diseases; and the Department of Agriculture.

Short of the comprehensive intervention, he said, many of the concepts can be put into practice by pediatricians and parents.

Dr. Paul noted that the Robert Wood Johnson Foundation has endorsed “responsive feeding” as the preferred approach to feeding infants and toddlers. Responsive feeding – helping parents recognize hunger and satiety cues as opposed to other distress cues – is a big part of the intervention.

“Feeding to soothe is not the preferred approach,” he said. “Food and milk and formula should be used for hunger.” That’s something pediatricians may not be stressing to parents, he said.

Pediatricians can also counsel parents on not using food as a reward. “We shouldn’t be giving kids M&Ms to teach them how to potty train,” he said.
 

‘Promising’ findings

Charles Wood, MD, a childhood obesity specialist at Duke University, Durham, N.C., who was not part of the study, called the findings “very promising.”

It also makes sense that the “aha moments” of first-time parents learning from the INSIGHT intervention would carry over to the second sibling, he said.

Dr. Wood agreed costs are a big factor. However, he said, the potential downstream costs of not preventing obesity are worse. And this study indicates the benefits may keep spreading with future siblings.

Dr. Wood said accessing obesity interventions outside the pediatrician visit can also help. Connecting patients with support groups or dietitians or with a counselor from Women, Infants, and Children can help. However, consistent messaging among the providers is key, he noted.

Dr. Wood’s research group is investigating text messaging platforms so parents can get answer to real-time questions, such as those about feeding behaviors.

He pointed to a limitation the authors mention, which is that the study was done in mostly White, highly educated, higher-income families.

“There’s a big problem with racial disparities and obesity,” Dr. Wood noted. “We definitely need solutions that address disparities as well.”

Mothers included in the study had given birth for the first time and their infants were enrolled after birth from a single maternity ward between January 2012 and March 2014. Major eligibility criteria were that the babies were full term (at least 37 weeks’ gestation), single births, and delivered to English-speaking mothers at least 20 years of age. Infants who weighed less than 2,500 g at birth were excluded.

The paper’s authors and Dr. Wood declared no relevant financial relationships.

Both Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are effective at improving hepatic steatosis in type 2 diabetes patients, according to a new analysis of a randomized, controlled trial.

Both procedures resulted in near elimination of liver fat 1 year after the surgery, but the effect on liver fibrosis was less clear. The authors called for more research to examine longer-term effects on fibrosis.

The amount of fat surrounding abdominal organs may help clinicians identify cardiovascular risk in young people with obesity, researchers have found.

Severely overweight children and young adults showed a subtle association between visceral fat and arterial stiffness independent of body mass index (BMI). The association was not present in those of healthy weight, possibly because their visceral fat stores are too small to have a detectable effect on cardiovascular health, according to the researchers, who reported their findings in the latest issue of Pediatric Obesity.

“Those kids with greater visceral fat had stiffer arteries, which can overtax and overstress the system and lead to unfortunate consequences in terms of cardiovascular health down the line,” senior author Joseph M. Kindler, PhD, an assistant professor of nutritional sciences at the University of Georgia, Athens, told this news organization.

The data came from cross-sectional measurements in 605 youth (67% female, 56% non-Black) aged 10-23 years at Cincinnati Children’s Hospital Medical Center. The sample included 236 individuals of healthy weight, 224 with obesity, and 145 with type 2 diabetes.    

Visceral fat was assessed with dual-energy x-ray absorptiometry (DXA), a widely used test of bone mineral density screening to assess fracture risk. Carotid-femoral pulse wave velocity (PWV) was used to gauge arterial stiffness, a subclinical sign of cardiovascular disease.

Visceral fat was associated with PWV in all three groups of study subjects (P < .05), the researchers found, whereas the amount of subcutaneous fat was linked to arterial stiffness in obese youth and those with obesity but not those whose weight was considered healthy.

The amount of fat was associated with an additional 1.6% of the variability in arterial stiffness in youth with obesity after accounting for BMI. Subcutaneous fat, meanwhile, did not appear to affect PWV, the researchers found. “In youth with healthy weight, visceral fat, subcutaneous fat, BMI, and waist circumference were not significantly associated with PWV in any analyses,” they write.

The researchers cited a paucity of data on the relationship between visceral fat and cardiovascular disease in children with obesity. Although BMI is a reliable and readily available indicator of risk for disease, DXA “might give us a little more information,” Dr. Kindler, a nutritionist and bone biologist, said. As for clinical use to supplement BMI and waist circumference, he said, “maybe there’s room for visceral fat, but we do need a lot more science to back those decisions down the line.”

For example, what normal visceral fat accumulation during childhood looks like is unknown, he said.

Rigorous longitudinal studies are needed to establish cause and effect, but the new findings offer “a potential connection between visceral fat and cardiovascular disease risk in youth in a relatively large sample,” Wei Shen, MD, MPH, the associate director of the body composition unit at the New York Obesity Nutrition Research Center at Columbia University, New York, said.

Ideally, said Dr. Shen, who was not involved in the latest study, it would be “more credible to use the most accurate measure of visceral fat, the volumetric measurement of visceral fat using MRI” to establish a causal relationship with cardiovascular risk. However, MRI is more expensive and less accessible than DXA. To assess visceral fat in the clinic, “waist circumference may still be a good choice, as it is so convenient to use,” she added.

Dr. Kindler and his colleagues highlighted the need to examine the effect of excess visceral fat as well as intrahepatic fat on youth with type 2 diabetes, who experience cardiovascular complications independent of whether they are obese. In the new study, the positive association between visceral fat and arterial stiffness did not differ between youth with obesity and normal glucose control and those with obesity and type 2 diabetes.

Funding came from the Endocrine Fellows Foundation, the National Institutes of Health, and the University of Georgia Obesity Initiative. Dr. Kindler and Dr. Shen have disclosed no relevant financial relationships.

Patients with obesity and type 2 diabetes who underwent bariatric surgery and had 10-year durable diabetes remission had a 60% lower risk of incident cancer than patients who had usual obesity care.

And women who had bariatric surgery had a 42% lower risk of having cancer during a median 21-year follow-up, compared with women who had usual obesity care.

These findings from 701 patients in the Swedish Obese Subjects (SOS) study who had type 2 diabetes were recently published in Diabetes Care.

The results illustrate the “connection between glucose control and cancer prevention” and suggest that “among patients with type 2 diabetes, many cancer cases are preventable,” lead author Kajsa Sjöholm, PhD, associate professor of molecular medicine at Sahlgrenska Academy, University of Gothenburg (Sweden), said in a press release from the university.

“The global epidemic of both obesity and diabetes leads to an increased risk of cancer, as well as an increased risk of premature death,” added senior author Magdalena Taube, PhD, associate professor of molecular medicine in the same academy.

“It has been estimated that, over the next 10-15 years, obesity may cause more cancer cases than smoking in several countries,” she noted. Therefore, “strategies are needed to prevent this development, and our results can provide vital guidance for prevention of cancer in patients with obesity and type 2 diabetes.”
 

Durable diabetes remission seems key

Two-thirds of the patients in the bariatric surgery group had vertical banded gastroplasty (65%), and the rest had adjustable or nonadjustable gastric banding (18%) or gastric bypass (17%).

Each type of bariatric surgery was associated with higher diabetes remission rates, compared with usual care, in a previous study by these researchers, Dr. Taube said in an interview.

“In our present study,” she added, “we observed a nonsignificant trend, where patients with obesity and type 2 diabetes in the highest weight loss tertile (average weight loss, –44.8 kg) had somewhat lower risk of cancer compared to the lowest tertile [average weight loss, –14.9 kg].”

This might suggest, Dr. Taube continued, that with respect to cancer risk, surgery techniques resulting in greater weight loss (for example, Roux-en-Y gastric bypass and sleeve gastrectomy) should be recommended in patients with obesity and diabetes.

“However, it should also be noted that long-term diabetes remission seems imperative for cancer risk reduction,” she said, “and in a recent meta-analysis by McTigue et al., published in JAMA Surgery, it was shown that patients who had Roux-en-Y gastric bypass had greater weight loss, a slightly higher type 2 diabetes remission rate, less type 2 diabetes relapse, and better long-term glycemic control, compared with those who had sleeve gastrectomy.

“The observed cancer reduction in women with obesity and type 2 diabetes is in line with previous findings showing that cancer risk reduction following bariatric surgery in patients with obesity is more marked among women than men,” Dr. Taube noted. This may be because cancer rates are higher in women with diabetes than in men with diabetes, and common cancer types associated with obesity are female specific.

The main cancers in women were breast cancer, followed by endometrial and colorectal cancer. In men, the main cancers were colorectal, prostate, and urothelial/malignant skin cancer.
 

Study design and findings

It is well established that obesity is a risk factor for 13 types of cancer, and some of these cancers (liver, pancreatic, endometrial, colon and rectal, breast, and bladder) may be related to type 2 diabetes. And bariatric surgery has been shown to reduce cancer risk in patients with obesity.

However, it is not clear how bariatric surgery may affect cancer risk in patients with obesity and type 2 diabetes.

To study this, the researchers examined data from 393 patients who underwent bariatric surgery and 308 patients who received usual obesity treatment, who were part of the SOS study.

The SOS study enrolled men with a body mass index of at least 34 kg/m², and women with a BMI of at least 38 kg/m² who were aged 37-60 years between 1987 and 2001.

The current study outcome – cancer incidence in patients with obesity and type 2 diabetes – was not a prespecified outcome

The intervention groups were matched on 18 variables, including age, sex, serum insulin, alcohol, education, and smoking.

At baseline, the patients had a mean age of about 49 and 60% were women. They had a mean BMI of about 42 and a mean hemoglobin A1c of 7.8%.

On average, patients in the surgery group had lost 27.5 kg and 22.7 kg, and patients in the usual care group had lost 3.2 kg and 4.8 kg, at 2 years and 10 years, respectively.

During a median follow-up of 21 years, there were 74 incident cancers in the control group and 68 cancers in the bariatric surgery group.

The risk of cancer during follow-up was 37% lower in the surgery group than in the usual care group, after multivariable adjustment (adjusted hazard ratio, 0.63; 95% confidence interval, 0.44-0.89; P = .008).

A deeper dive showed that there were 86 incident cancers in women and 56 cancers in men. The risk of cancer was significantly lower in women who had bariatric surgery, compared with those who had usual care (aHR, 0.58; 95% CI 0.38-0.90, P = .016). However, the risk of cancer was not significantly lower in men who had bariatric surgery versus those who had usual care (aHR 0.79, 95% CI, 0.46-1.38; P = .413).

Diabetes remission at 10 years was associated with a 60% reduced cancer incidence (aHR, 0.40; 95% CI, 0.22-0.74, P = .003).

The study was funded by the Swedish state (under an agreement between the Swedish government and the county councils), the Swedish Research Council, the Novo Nordisk Foundation, the Swedish Heart-Lung Foundation, and the Swedish Diabetes Foundation. One author received consulting fees from Johnson & Johnson. The other authors had no relevant financial disclosures.

The cardiovascular and cardiometabolic effects of therapy in women with breast cancer vary based on patient factors like weight and menopausal status, according to findings from the Pathways Heart Study recently presented at the San Antonio Breast Cancer Symposium.

Fred Hutchinson Cancer Center

For example, certain chemotherapy drugs may confer higher risk in breast cancer survivors of normal weight, whereas they may lower stroke risk in those who are obese, according to Heather Greenlee, ND, PhD, a public health researcher and naturopathic physician with the Fred Hutchinson Cancer Research Center in Seattle.

In postmenopausal women with breast cancer, aromatase inhibitors may increase cardiovascular risk, while tamoxifen appears to reduce the risk of incident dyslipidemia, she said.

The findings are from separate analyses of data from studies presented during a poster discussion session at the symposium.
 

Breast cancer treatment and cardiovascular effects: The role of weight

In one analysis, Dr. Greenlee and colleagues examined outcomes in 13,582 breast cancer survivors with a median age of 60 years and median follow-up of 7 years to assess whether cardiovascular disease (CVD) risk associated with specific breast cancer therapies varies by body mass index (BMI) category at diagnosis.

Many routinely used breast cancer therapies are cardiotoxic, and being overweight or obese are known risk factors for CVD, but few studies have assessed whether BMI modifies the effect of these treatment on cardiovascular risk, Dr. Greenlee explained.

After adjusting for baseline demographic and health-related factors, and other breast cancer treatment, they found that:

• Ischemic heart disease risk was higher among normal-weight women who received anthracyclines, compared with those who did not (hazard ratio, 4.2). No other risk associations were observed for other breast cancer therapies and BMI groups.
• Heart failure/cardiomyopathy risk was higher among women with normal weight who received anthracyclines, cyclophosphamides, or left-sided radiation, compared with those who did not (HRs, 5.24, 3.27, and 2.05, respectively), and among overweight women who received anthracyclines, compared with those who did not (HR, 2.18). No risk associations were observed for women who received trastuzumab, taxanes, endocrine therapy, or radiation on any side, and no risk associations were observed for women who were obese.
• Stroke risk was higher in normal-weight women who received taxanes, cyclophosphamides, or left-sided radiation versus those who did not (HRs, 2.14, 2.35, and 1.31, respectively), and stroke risk was lower in obese women who received anthracyclines, taxanes, or cyclophosphamide, compared with those who did not (HRs, 0.32, 0.41, and 0.29, respectively). No risk associations were observed for trastuzumab, endocrine therapy, or radiation on any side, and no risk associations were observed for women who were overweight.

The lack of associations noted between treatments and heart failure risk among obese patients could be caused by the “obesity paradox” observed in prior obese populations, the investigators noted, adding that additional analyses are planned to “examine whether different dosage and duration of breast cancer therapy exposures across the BMI groups contributed to these risk associations.”
 

Breast cancer treatment and cardiometabolic effects: The role of menopausal status

In a separate analysis, Dr. Greenlee and colleagues looked at the association between endocrine therapies and cardiometabolic risk based on menopausal status.

Endocrine therapy is associated with CVD in breast cancer survivors and may be associated with developing cardiometabolic risk factors like diabetes, dyslipidemia, and hypertension, they noted, explaining that tamoxifen has mixed estrogenic and antiestrogenic activity, while aromatase inhibitors deplete endogenous estrogen.

Since most studies have compared tamoxifen with aromatase inhibitor use, it has been a challenge challenging to discern the effects of each, Dr. Greenlee said.

She and her colleagues reviewed records for 14,942 breast cancer survivors who were diagnosed between 2005 and 2013. The patients had a mean age of 61 years at baseline, and 24.9% were premenopausal at the time of diagnosis. Of the premenopausal women, 27.3% used tamoxifen, 19.2% used aromatase inhibitors, and 53.5% did not use endocrine therapy, and of the postmenopausal women, 6.6% used tamoxifen, 47.7% used aromatase inhibitors, and 45.7% did not use endocrine therapy.

After adjusting for baseline demographics and health factors, the investigators found that:

• The use of tamoxifen or aromatase inhibitors was not associated with a risk of developing diabetes, dyslipidemia, or hypertension in premenopausal women, or with a risk of developing diabetes or hypertension in postmenopausal women.
• The risk of dyslipidemia was higher in postmenopausal aromatase inhibitor users, and lower in postmenopausal tamoxifen users, compared with postmenopausal non-users of endocrine therapy (HRs, 1.15 and 0.75, respectively).

The lack of associations between endocrine therapy and CVD risk in premenopausal women may be from low power, Dr. Greenlee said, noting that analyses in larger sample sizes are needed.

She and her colleagues plan to conduct further analyses looking at treatment dosage and duration, and comparing steroidal versus nonsteroidal aromatase inhibitors.

Future studies should examine the implications of these associations on long-term CVD and how best to manage lipid profiles in postmenopausal breast cancer survivors who have a history of endocrine therapy treatment, they concluded.

This research was funded by grants from the National Cancer Institute.

The cardiovascular and cardiometabolic effects of therapy in women with breast cancer vary based on patient factors like weight and menopausal status, according to findings from the Pathways Heart Study recently presented at the San Antonio Breast Cancer Symposium.

Fred Hutchinson Cancer Center

For example, certain chemotherapy drugs may confer higher risk in breast cancer survivors of normal weight, whereas they may lower stroke risk in those who are obese, according to Heather Greenlee, ND, PhD, a public health researcher and naturopathic physician with the Fred Hutchinson Cancer Research Center in Seattle.

In postmenopausal women with breast cancer, aromatase inhibitors may increase cardiovascular risk, while tamoxifen appears to reduce the risk of incident dyslipidemia, she said.

The findings are from separate analyses of data from studies presented during a poster discussion session at the symposium.

Higher resting heart rate (RHR) is associated with increased risk for dementia and accelerated cognitive decline in older adults, independent of the presence of cardiovascular disease (CVD) risk factors, new research shows.

“RHR is easy to measure and might be used to identify older people potentially at high risk of dementia and cognitive decline for early interventions,” Yume Imahori, MD, PhD, with the Aging Research Center, Karolinska Institutet, Stockholm, said in an interview.

“Health care professionals should be aware of potential cognitive consequences associated with elevated RHR in older people and may advise older people with high RHR to have a follow-up assessment of cognitive function,” Dr. Imahori said.

The study was published online Dec. 3, 2021, in Alzheimer’s & Dementia.
 

Heart-brain connection

The findings are based on 2,147 adults (62% women) aged 60 years and older (mean age, 70.6 years) from the population-based Swedish National Aging and Care in Kungsholmen (SNAC-K) study. All were free of dementia at baseline and were followed regularly from 2001-2004 to 2013-2016.

The average RHR at baseline was 65.7 bpm. Individuals in higher RHR groups were older, less educated, and were more likely to be smokers and sedentary and to have hypertension. There were no differences among RHR groups in the prevalence of CVD at baseline.

During a median follow-up of 11.4 years, 289 participants were diagnosed with dementia.

In the fully adjusted model, participants with RHR of 80 bpm or higher had a 55% increased risk of developing dementia, compared with peers with lower RHR of 60 to 69 bpm (hazard ratio, 1.55; 95% CI, 1.06-2.27).

“This association was not due to underlying cardiovascular diseases such as atrial fibrillation and heart failure, which is important because elevated RHR is often related to heart disease,” Dr. Imahori said in an interview.

Regarding cognitive function, Mini-Mental State Examination scores declined over time during the follow-up period in all RHR groups, but participants with RHR 70-79 and 80+ bpm had a greater decline, compared with those with lower RHR of 60-69 bpm.

Dr. Imahori said these findings are in line with data from the U.S. Atherosclerosis Risk in Communities study linking elevated RHR of 80+ bpm in midlife to dementia and cognitive decline in late life.
 

Public health implications

Reached for comment, Claire Sexton, DPhil, Alzheimer’s Association director of scientific programs and outreach, said this study adds to the “growing body of research showing the health of the heart and brain are closely connected. However, this study only shows a correlation between resting heart rate and cognition, not causation. More research is needed.

“Evidence shows that other risk factors for cardiovascular disease and stroke – obesity, high blood pressure, and diabetes – negatively impact your cognitive health,” Dr. Sexton said in an interview.

“The Alzheimer’s Association believes the conversation about heart health management is something everyone should be having with their doctor,” she said.

“There are things you can do today to lower your risk for cardiovascular disease, including regular exercise and maintaining a healthy diet. Improving your heart health is an important step to maintaining your brain health as you age,” Dr. Sexton added.

SNAC-K is supported by the Swedish Ministry of Health and Social Affairs and the participating county councils and municipalities and in part by additional grants from the Swedish Research Council and the Swedish Research Council for Health, Working Life and Welfare. Dr. Imahori and Dr. Sexton disclosed no relevant financial relationships.

Evidence summary

Multiple analyses suggest short sleep increases obesity risk

Three recent, large systematic reviews of prospective cohort studies with meta-analyses in infants, children, and adolescents all found associations between short sleep at intake and later excessive weight.

The largest meta-analysis included 42 prospective studies with 75,499 patients ranging in age from infancy to adolescence and with follow-up ranging from 1 to 27 years. In a pooled analysis, short sleep—variously defined across trials and mostly assessed by parental report—was associated with an increased risk of obesity or overweight (relative risk [RR] = 1.58; 95% CI, 1.35-1.85; I²= 92%), compared to normal and long sleep. When the authors adjusted for suspected publication bias using a “trim and fill” method, short sleep remained associated with later overweight or obesity (RR = 1.42; 95% CI, 1.12-1.81). Short sleep was associated with later unhealthy weight status in all age groups: 0 to < 3 years (RR = 1.4; 95% CI, 1.19-1.65); 3 to < 9 years (RR = 1.57; 95% CI, 1.4-1.76);9 to < 12 years (RR = 2.23; 95% CI, 2.18-2.27); and 12 to 18 years (RR = 1.3; 95% CI, 1.11-1.53). In addition to high heterogeneity, limitations of the review included variability in the definition of short sleep, use of parent- or self-reported sleep duration, and variability in classification of overweight and obesity in primary studies.¹

A second systematic review and meta-analysis included 25 longitudinal studies (20 of which overlapped with the previously discussed meta-analysis) of children and adolescents (N = 56,584). Patients ranged in age from infancy to 16 years, and follow-up ranged from 6 months to 10 years (mean, 3.4 years). Children and adolescents with the shortest sleep duration were more likely to be overweight or obese at follow-up (pooled odds ratio [OR] = 1.76; 95% CI, 1.39-2.23; I² = 70.5%) than those with the longest sleep duration. Due to the overlap in studies, the limitations of this analysis were similar to those already mentioned. Lack of a linear association between sleep duration and weight was cited as evidence of possible publication bias; the authors did not attempt to correct for it.²

Three large systematic reviews all found associations between short sleep at intake and later excessive weight.

The third systematic review and meta-analysis included 22 longitudinal studies (18 overlapped with first meta-analysis and 17 with the second) of children and adolescents (N = 24,821) ages 6 months to 18 years. Follow-up ranged from 1 to 27 years. This meta-analysis standardized the categories of sleep duration using recommendations from the Sleep Health Foundation. Patients with short sleep duration had an increased risk of overweight or obesity compared with patients sleeping “normal” or “longer than normal” durations (pooled OR = 2.15; 95% CI, 1.64-2.81; I² = 67%). The authors indicated that their analysis could have been more robust if information about daytime sleep (ie, napping) had been available, but it was not collected in many of the included studies.³

Accelerometer data quantify the sleep/obesity association

A subsequent cohort study (N = 202) sought to better examine the association between sleep characteristics and adiposity by measuring sleep duration using accelerometers. Toddlers (ages 12 to 26 months) without previous medical history were recruited from early childhood education centers. Patients wore accelerometers for 7 consecutive days and then returned to the clinic after 12 months for collection of biometric information. Researchers measured body morphology with the BMI z-score (ie, the number of standard deviations from the mean). Every additional hour of total sleep time was associated with a 0.12-unit lower BMI z-score (95% CI, –0.23 to –0.01) at 1 year. However, every hour increase in nap duration was associated with a 0.41-unit higher BMI z-score (95% CI, 0.14-0.68).⁴

Recommendations from others

In 2016, the American Academy of Sleep Medicine (AASM) recommended the following sleep durations (per 24 hours): infants ages 4 to 12 months, 12-16 hours; children 1 to 2 years, 11-14 hours; children 3 to 5 years, 10-13 hours; children 6 to 12 years, 9-12 hours; and teenagers 13 to 18 years, 8-10 hours. The AASM further stated that sleeping the recommended number of hours was associated with better health outcomes, and that sleeping too few hours increased the risk of various health conditions, including obesity.⁵ In 2015, the American Academy of Pediatrics Committee on Nutrition acknowledged the association between obesity and short sleep duration and recommended that health care professionals counsel parents about age-appropriate sleep guidelines.⁶

Editor’s takeaway

Studies demonstrate that short sleep duration in pediatric patients is associated with later weight gain. However, associations do not prove a causal link, and other factors may contribute to both weight gain and poor sleep.

Three large systematic reviews all found associations between short sleep at intake and later excessive weight.

The third systematic review and meta-analysis included 22 longitudinal studies (18 overlapped with first meta-analysis and 17 with the second) of children and adolescents (N = 24,821) ages 6 months to 18 years. Follow-up ranged from 1 to 27 years. This meta-analysis standardized the categories of sleep duration using recommendations from the Sleep Health Foundation. Patients with short sleep duration had an increased risk of overweight or obesity compared with patients sleeping “normal” or “longer than normal” durations (pooled OR = 2.15; 95% CI, 1.64-2.81; I² = 67%). The authors indicated that their analysis could have been more robust if information about daytime sleep (ie, napping) had been available, but it was not collected in many of the included studies.³

Accelerometer data quantify the sleep/obesity association

A subsequent cohort study (N = 202) sought to better examine the association between sleep characteristics and adiposity by measuring sleep duration using accelerometers. Toddlers (ages 12 to 26 months) without previous medical history were recruited from early childhood education centers. Patients wore accelerometers for 7 consecutive days and then returned to the clinic after 12 months for collection of biometric information. Researchers measured body morphology with the BMI z-score (ie, the number of standard deviations from the mean). Every additional hour of total sleep time was associated with a 0.12-unit lower BMI z-score (95% CI, –0.23 to –0.01) at 1 year. However, every hour increase in nap duration was associated with a 0.41-unit higher BMI z-score (95% CI, 0.14-0.68).⁴

Recommendations from others

In 2016, the American Academy of Sleep Medicine (AASM) recommended the following sleep durations (per 24 hours): infants ages 4 to 12 months, 12-16 hours; children 1 to 2 years, 11-14 hours; children 3 to 5 years, 10-13 hours; children 6 to 12 years, 9-12 hours; and teenagers 13 to 18 years, 8-10 hours. The AASM further stated that sleeping the recommended number of hours was associated with better health outcomes, and that sleeping too few hours increased the risk of various health conditions, including obesity.⁵ In 2015, the American Academy of Pediatrics Committee on Nutrition acknowledged the association between obesity and short sleep duration and recommended that health care professionals counsel parents about age-appropriate sleep guidelines.⁶

Editor’s takeaway

Studies demonstrate that short sleep duration in pediatric patients is associated with later weight gain. However, associations do not prove a causal link, and other factors may contribute to both weight gain and poor sleep.

Evidence summary

Multiple analyses suggest short sleep increases obesity risk

Three recent, large systematic reviews of prospective cohort studies with meta-analyses in infants, children, and adolescents all found associations between short sleep at intake and later excessive weight.

The largest meta-analysis included 42 prospective studies with 75,499 patients ranging in age from infancy to adolescence and with follow-up ranging from 1 to 27 years. In a pooled analysis, short sleep—variously defined across trials and mostly assessed by parental report—was associated with an increased risk of obesity or overweight (relative risk [RR] = 1.58; 95% CI, 1.35-1.85; I²= 92%), compared to normal and long sleep. When the authors adjusted for suspected publication bias using a “trim and fill” method, short sleep remained associated with later overweight or obesity (RR = 1.42; 95% CI, 1.12-1.81). Short sleep was associated with later unhealthy weight status in all age groups: 0 to < 3 years (RR = 1.4; 95% CI, 1.19-1.65); 3 to < 9 years (RR = 1.57; 95% CI, 1.4-1.76);9 to < 12 years (RR = 2.23; 95% CI, 2.18-2.27); and 12 to 18 years (RR = 1.3; 95% CI, 1.11-1.53). In addition to high heterogeneity, limitations of the review included variability in the definition of short sleep, use of parent- or self-reported sleep duration, and variability in classification of overweight and obesity in primary studies.¹

A second systematic review and meta-analysis included 25 longitudinal studies (20 of which overlapped with the previously discussed meta-analysis) of children and adolescents (N = 56,584). Patients ranged in age from infancy to 16 years, and follow-up ranged from 6 months to 10 years (mean, 3.4 years). Children and adolescents with the shortest sleep duration were more likely to be overweight or obese at follow-up (pooled odds ratio [OR] = 1.76; 95% CI, 1.39-2.23; I² = 70.5%) than those with the longest sleep duration. Due to the overlap in studies, the limitations of this analysis were similar to those already mentioned. Lack of a linear association between sleep duration and weight was cited as evidence of possible publication bias; the authors did not attempt to correct for it.²
