Obesity

The younger an ICU patient with severe COVID-19 is, the more obese that patient tends to be, according to a new analysis published in The Lancet.

“By itself, obesity seems to be a sufficient risk factor to start seeing younger people landing in the ICU,” said the study’s lead author, David Kass, MD, a professor of cardiology and medicine at Johns Hopkins University School of Medicine in Baltimore, Maryland.

“In that sense, there’s a simple message: If you’re very, very overweight, don’t think that if you’re 35 you’re that much safer [from severe COVID-19] than your mother or grandparents or others in their 60s or 70s,” Kass told Medscape Medical News.

The findings, which Kass describes as a “2-week snapshot” of 265 patients (58% male) in late March and early April at a handful of university hospitals in the United States reinforces other recent research indicating that obesity is one of the biggest risk factors for severe COVID-19 disease, particularly among younger patients. In addition, a large British study showed that, after adjusting for comorbidities, obesity was a significant factor associated with in-hospital death in COVID-19.

But this new analysis stands out as the only dataset to date that specifically “asks the question relative to age” of whether severe COVID-19 disease correlates to ICU treatment, he said.

The mean age of his study population of ICU patients was 55, Kass said, “and that was young, not what we were expecting.”

“Even with the first 20 patients, we were already seeing younger people and they definitely were heavier, with plenty of patients with a BMI over 35 kg/m²,” he added. “The relationship was pretty tight, pretty quick.”

“Just don’t make the assumption that any of us are too young to be vulnerable if, in fact, this is an aspect of our bodies,” he said.

Steven Heymsfield, MD, past president and a spokesperson for the Obesity Society, agrees with Kass’ conclusions.

“One thing we’ve had on our minds is that the prototype of a person with this disease is older...but now if we get [a patient] who’s symptomatic and 40 and obese, we shouldn’t assume they have some other disease,” Heymsfield told Medscape Medical News.

“We should think of them as a susceptible population.”

Kass and colleagues agree. “Public messaging to younger adults, reducing the threshold for virus testing in obese individuals, and maintaining greater vigilance for this at-risk population should reduce the prevalence of severe COVID-19 disease [among those with obesity],” they state.

“I think it’s a mental adjustment from a health care standpoint, which might hopefully help target the folks who are at higher risk before they get into trouble,” Kass told Medscape Medical News.
 

Trio of mechanisms explain obesity’s extra COVID-19 risks

Kass and coauthors write that, in analyzing their data, they anticipated similar results to the largest study of 1591 ICU patients from Italy in which only 203 were younger than 51 years. Common comorbidities among those patients included hypertension, cardiovascular disease, and type 2 diabetes, with similar data reported from China.

When the COVID-19 epidemic accelerated in the United States, older age was also identified as a risk factor. Obesity had not yet been added to this list, Kass noted. But following informal discussions with colleagues in other ICUs around the country, he decided to investigate further as to whether it was an underappreciated risk factor.

Kass and colleagues did a quick evaluation of the link between BMI and age of patients with COVID-19 admitted to ICUs at Johns Hopkins, University of Cincinnati, New York University, University of Washington, Florida Health, and University of Pennsylvania.

The “significant inverse correlation between age and BMI” showed younger ICU patients were more likely to be obese, with no difference by gender.

Median BMI among study participants was 29.3 kg/m², with only a quarter having a BMI lower than 26 kg/m² and another 25% having a BMI higher than 34.7 kg/m².

Kass acknowledged that it wasn’t possible with this simple dataset to account for any other potential confounders, but he told Medscape Medical News that, “while diabetes, cardiovascular disease, and hypertension, for example, can occur with obesity, this is generally less so in younger populations as it takes time for the other comorbidities to develop.”

He said several mechanisms could explain why obesity predisposes patients with COVID-19 to severe disease.

For one, obesity places extra pressure on the diaphragm while lying on the back, restricting breathing.

“Morbid obesity itself is sort of proinflammatory,” he continued.

“Here we’ve got a viral infection where the early reports suggest that cytokine storms and immune mishandling of the virus are why it’s so much more severe than other forms of coronavirus we’ve seen before. So if you have someone with an already underlying proinflammatory state, this could be a reason there’s higher risk.”

Additionally, the angiotensin-converting enzyme-2 (ACE-2) receptor to which the SARS-CoV-2 virus that causes COVID-19 attaches is expressed in higher amounts in adipose tissue than the lungs, Kass noted.

“This could turn into kind of a viral replication depot,” he explained. “You may well be brewing more virus as a component of obesity.”
 

Sensitivity needed in public messaging about risks, but test sooner

With an obesity rate of about 40% in the United States, the results are particularly relevant for Americans, Kass and Heymsfield say, noting that the country’s “obesity belt” runs through the South.

Heymsfield, who wasn’t part of the new analysis, notes that public messaging around severe COVID-19 risks to younger adults with obesity is “tricky,” especially because the virus is “still pretty common in nonobese people.”

Kass agrees, noting, “it’s difficult to turn to 40% of the population and say: ‘You guys have to watch it.’ ”

But the mounting research findings necessitate linking obesity with severe COVID-19 disease and perhaps testing patients in this category for the virus sooner before symptoms become severe.

And of note, since shortness of breath is common among people with obesity regardless of illness, similar COVID-19 symptoms might catch these individuals unaware, pointed out Heymsfield, who is also a professor in the Metabolism and Body Composition Lab at Pennington Biomedical Research Center at Louisiana State University, Baton Rouge.

“They may find themselves literally unable to breathe, and the concern would be that they wait much too long to come in” for treatment, he said. Typically, people can deteriorate between day 7 and 10 of the COVID-19 infection.

Individuals with obesity “need to be educated to recognize the serious complications of COVID-19 often appear suddenly, although the virus has sometimes been working its way through the body for a long time,” he concluded.

Kass and Heymsfield have declared no relevant financial relationships.

First responders to the site of the 2001 World Trade Center attack may have an elevated risk of nonalcoholic fatty liver disease (NAFLD), according to investigators.

In a retrospective look at 236 first responders presenting with gastrointestinal symptoms to the World Trade Center Health Program, 195 (82.6%) had NAFLD, compared with 24%-45% of the general population, reported lead author Mishal Reja, MD, of Robert Wood Johnson University Hospital, New Brunswick, N.J.

The increased rate of NAFLD among first responders is likely because of toxin exposure at ground zero, which can cause a subtype of NAFLD known as toxin-associated fatty liver disease (TAFLD), Dr. Reja wrote in an abstract released as part of the annual Digestive Disease Week^®, which was canceled because of COVID-19.

“I was not surprised [by these findings],” Dr. Reja said during a virtual press conference. “In the prior literature that did examine TAFLD, it did show that populations exposed to these specific chemicals ... at the ground zero site had extremely high rates – consistent with the rates we found in our study – of fatty liver disease.”

Dr. Reja said that 9/11 first responders were exposed to “many common toxins that are consistently in occupational and environmental toxicant literature.” In particular, he named polycyclic aromatic hydrocarbons and vinyl chloride.

“A lot of these toxins are ... included in industrial solvents as well as building demolition,” Dr. Reja said. “So they’ve been around for so long, and they’ve been studied for so long, [that we have] literature that shows these toxins are associated with fatty liver disease, which is how we arrived at the hypothesis in the first place.”

The first responders were stratified by roles, which were associated with varying levels of exposure. About 40% of individuals in the study were involved in moving debris from the site, a small group (4%) were involved in clean-up and maintenance, while approximately 30%-40% worked in more protected, administrative roles.

Comparing individuals in the study with TAFLD versus those without TAFLD revealed additional risk factors. Multivariate logistical regression analysis showed that obese individuals had a significantly increased risk of fatty liver disease, suggesting a synergistic effect.

“If you were exposed to these toxins in the World Trade Center, and you were obese, [then] you are actually between two to three times more likely to get [TAFLD],” Dr. Reja said, noting that hypertension and diabetes were also identified as independent risk factors.

Dr. Reja and colleagues are planning a prospective trial to investigate further. The study will likely involve 100-200 first responders with TAFLD, a similar number of individuals with NAFLD, and another group without liver disease.

The investigators reported no outside funding or conflicts of interest.

Readily available and inexpensive noninvasive tests, when used in combination with liver markers obtained with the extra-large probe, can improve the ability to predict risk for decompensation and other adverse outcomes in obese and overweight patients with compensated advanced chronic liver disease (cACLD), according to study results reported in the upcoming issue of the journal Clinical Gastroenterology and Hepatology.

The retrospective study of 272 obese and overweight patients in Bern, Switzerland, and Montreal with cACLD is the first to fully assess the noninvasive marker of portal hypertension along with using the extra-large probe for controlled attenuation parameter (CAP) to determine risk, wrote Yuly Mendoza, MD, of the University of Bern and colleagues. Decompensation in cACLD carries a higher risk of death. The study noted that portal hypertension is a key driver of progression to decompensation, “and as such, it should be identified as soon as possible and treated as needed.”

“Prediction of prognosis in cACLD is challenging, and noninvasive tests are important tools for clinicians to avoid as much as possible the use of more invasive tests,” wrote Dr. Mendoza and colleagues. Based on the extra-large probe, 76% (n = 206) of study patients had metabolic syndrome, sometimes with other etiologies of liver disease, and 57% (n = 154) had cACLD because of nonalcoholic fatty liver disease/nonalcoholic steatohepatitis (NAFLD/NASH).

Twelve patients had decompensation and five developed severe bacterial infections.

“Readily available noninvasive tests can be used to identify obese or overweight patients with cACLD who are at increased risk for decompensation and severe bacterial infections,” wrote the researchers.

The study noted that obesity is a challenge for noninvasive tests and is a major limitation to liver stiffness measurement on transient elastography using the standard M probe. The XL probe has been specifically designed to overcome this challenge in obese patients, but it hasn’t been evaluated for the prediction of clinical decompensation in obese patients with cACLD.

This study claimed to provide further evidence that liver stiffness measurement in combination with noninvasive tests for liver stiffness measurement, spleen size/platelet count (LSPS), portal hypertension and portal hypertension risk score can help identify patients at risk for clinical decompensation and severe bacterial infections.

The study used average area under the receiving operator curve (AUC) to calculate the ability of the markers to distinguish risk, all with 95% confidence interval: 0.803 for liver stiffness measurement, 0.829 for portal hypertension risk score, and 0.845 for LSPS (P < .001). The markers showed an even better ability to differentiate between patients at risk for developing classical clinical decompensation in follow-up from those not at risk (all 95% CI): 0.848 for liver stiffness measurement, 0.881 for portal hypertension risk score, and 0.890 for LSPS (P < .001).

“The results of the present study validate the use of [extra-large] probe for liver stiffness measurement and CAP to stratify the risk of clinical decompensation and clinically relevant events in overweight/obese patients with cACLD, particularly in case of NAFLD/NASH etiology,” wrote Dr. Mendoza and colleagues.

All study participants were followed for at least 6 months, with a median of 17 months. Patients who developed decompensation or severe bacterial infections had slightly worse liver function (higher international normalized ratio and lower albumin), lower mean platelet count (117 vs. 179 x 10⁹/L; P < .001) and lower mean CAP (297 vs. 318 dBm; P = .030) than did patients who stayed compensated.

CAP above 220 dB/m was marginally associated with a lower risk of decompensation or severe bacterial infections on univariate analysis, as were elevated Model for End-Stage Liver Disease score, elevated Child Pugh score, low platelet count, low serum albumin, elevated serum bilirubin and increased liver stiffness measurement, LSPS, and portal hypertension risk scores.

Dr. Mendoza and colleagues have no relevant financial disclosures. The study received funding from the Swiss government.

The study used average area under the receiving operator curve (AUC) to calculate the ability of the markers to distinguish risk, all with 95% confidence interval: 0.803 for liver stiffness measurement, 0.829 for portal hypertension risk score, and 0.845 for LSPS (P < .001). The markers showed an even better ability to differentiate between patients at risk for developing classical clinical decompensation in follow-up from those not at risk (all 95% CI): 0.848 for liver stiffness measurement, 0.881 for portal hypertension risk score, and 0.890 for LSPS (P < .001).

“The results of the present study validate the use of [extra-large] probe for liver stiffness measurement and CAP to stratify the risk of clinical decompensation and clinically relevant events in overweight/obese patients with cACLD, particularly in case of NAFLD/NASH etiology,” wrote Dr. Mendoza and colleagues.

All study participants were followed for at least 6 months, with a median of 17 months. Patients who developed decompensation or severe bacterial infections had slightly worse liver function (higher international normalized ratio and lower albumin), lower mean platelet count (117 vs. 179 x 10⁹/L; P < .001) and lower mean CAP (297 vs. 318 dBm; P = .030) than did patients who stayed compensated.

CAP above 220 dB/m was marginally associated with a lower risk of decompensation or severe bacterial infections on univariate analysis, as were elevated Model for End-Stage Liver Disease score, elevated Child Pugh score, low platelet count, low serum albumin, elevated serum bilirubin and increased liver stiffness measurement, LSPS, and portal hypertension risk scores.

Readily available and inexpensive noninvasive tests, when used in combination with liver markers obtained with the extra-large probe, can improve the ability to predict risk for decompensation and other adverse outcomes in obese and overweight patients with compensated advanced chronic liver disease (cACLD), according to study results reported in the upcoming issue of the journal Clinical Gastroenterology and Hepatology.

The retrospective study of 272 obese and overweight patients in Bern, Switzerland, and Montreal with cACLD is the first to fully assess the noninvasive marker of portal hypertension along with using the extra-large probe for controlled attenuation parameter (CAP) to determine risk, wrote Yuly Mendoza, MD, of the University of Bern and colleagues. Decompensation in cACLD carries a higher risk of death. The study noted that portal hypertension is a key driver of progression to decompensation, “and as such, it should be identified as soon as possible and treated as needed.”

“Prediction of prognosis in cACLD is challenging, and noninvasive tests are important tools for clinicians to avoid as much as possible the use of more invasive tests,” wrote Dr. Mendoza and colleagues. Based on the extra-large probe, 76% (n = 206) of study patients had metabolic syndrome, sometimes with other etiologies of liver disease, and 57% (n = 154) had cACLD because of nonalcoholic fatty liver disease/nonalcoholic steatohepatitis (NAFLD/NASH).

Twelve patients had decompensation and five developed severe bacterial infections.

“Readily available noninvasive tests can be used to identify obese or overweight patients with cACLD who are at increased risk for decompensation and severe bacterial infections,” wrote the researchers.

The study noted that obesity is a challenge for noninvasive tests and is a major limitation to liver stiffness measurement on transient elastography using the standard M probe. The XL probe has been specifically designed to overcome this challenge in obese patients, but it hasn’t been evaluated for the prediction of clinical decompensation in obese patients with cACLD.

The results of two postapproval studies confirm the potential risk of hyperinflation and acute pancreatitis with the Orbera and ReShape liquid-filled intragastric balloon systems used to treat obesity.

The Orbera Intragastric Balloon System is manufactured by Apollo Endosurgery. The ReShape Integrated Dual Balloon System was previously manufactured by ReShape Medical but was acquired by Apollo Endosurgery in December 2018.

In the Orbera postapproval study, 6 of 258 patients (2.3%) experienced balloon hyperinflation, the Food and Drug Administration said today in a letter to health care providers. There were no hyperinflation events detected in the ReShape postapproval study.

Acute pancreatitis was reported in 2 of 159 patients (1.3%) in the ReShape study, with no cases of acute pancreatitis reported in the Orbera study.

No balloon hyperinflation or acute pancreatitis events were reported in the studies the companies submitted to the FDA to gain approval, the agency said.

No deaths were reported in the postapproval studies, though the agency notes that the studies were not powered to detect. However, since Orbera and ReShape were approved in 2015, the FDA has learned of 18 deaths worldwide, including 8 patients in the United States (5 with Orbera and 3 with ReShape).

The FDA issued previous letters to health care providers concerning issues with these devices in June 2018, August 2017, and February 2017.

As of Jan. 1, 2019, Apollo Endosurgery stopped selling the ReShape Balloon. The Orbera balloon remains available.

“The FDA wants to ensure healthcare professionals are aware of the rates of these potential complications observed in the post-approval studies so they can discuss the risks and benefits of weight loss treatments with patients and monitor patients during treatment,” Benjamin Fisher, PhD, director of the Reproductive, Gastro-Renal, Urological, General Hospital Device, and Human Factors Office at the FDA’s Center for Devices and Radiological Health, said in a statement.

“While these devices remain an appropriate treatment option for some patients with obesity, patients should always discuss with their doctors which treatment option is best for them,” said Dr. Fisher.

It is becoming increasingly clear that obesity is one of the biggest risk factors for severe COVID-19 disease, particularly among younger patients.

Newly published data from New York show that, among those aged under 60 years, obesity was twice as likely to result in hospitalization for COVID-19 and also significantly increased the likelihood that a person would end up in intensive care.

“Obesity [in people younger than 60] appears to be a previously unrecognized risk factor for hospital admission and need for critical care. This has important and practical implications when nearly 40% of adults in the U.S. are obese with a body mass index [BMI] of [at least] 30,” wrote Jennifer Lighter, MD, of New York University Langone Health, and colleagues in their research letter published in Clinical Infectious Diseases.

Similar findings in a preprint publication, yet to be peer reviewed, from another New York hospital show that, with the exception of older age, obesity (BMI greater than 40 kg/m²) had the strongest association with hospitalization for COVID-19, increasing the risk more than 500%.

Meanwhile, a new French study shows a high frequency of obesity among patients admitted to one ICU for COVID-19; furthermore, disease severity increased with increasing BMI. One of the authors said in an interview that many of the presenting patients were younger, with their only risk factor being obesity.

“Patients with obesity should avoid any COVID-19 contamination by enforcing all prevention measures during the current pandemic,” wrote the authors, led by Arthur Simonnet, MD, Centre Hospitalier Universitaire de Lille (France).

They also stressed that COVID-19 patients “with severe obesity should be monitored more closely.”
 

Those with obesity are young and become very sick, very quickly

François Pattou, MD, PhD, coauthor of the French article published in Obesity said in an interview that, when patients with COVID-19 began to arrive at their ICU in Lille, there were young patients who did not have any other comorbidities.

“They were just obese,” he observed, adding that they seemed “to have a very specific disease, something different” from that seen before, with patients becoming very sick, very quickly.

In their study, they examined 124 consecutive patients admitted to intensive care with COVID-19 between Feb. 25 and April 5, 2020, and compared them with a historical control group of 306 patients admitted to the ICU at the same hospital for non–COVID-19-related severe acute respiratory disease in 2019.

By April 6, 60 patients with COVID-19 had been discharged from intensive care, 18 had died, and 46 remained in the unit. The majority (73%) were male, and their median age was 60 years. Obesity and severe obesity were significantly more prevalent among the patients with COVID-19, at 47.6% and 28.2% versus 25.2% and 10.8% among historical controls (P < .001 for trend).

A key finding was that those with a BMI greater than 35 had a more than 600% increased risk of requiring mechanical ventilation (odds ratio, 7.36; P = .021), compared with those with a BMI less than 25, even after adjusting for age, diabetes, and hypertension.
 

Obesity in under 60s at least doubles risk of admission in U.S.

The studies out of New York, one of which was stratified by age, paint a similar picture.

Dr. Lighter and colleagues found that, of the 3,615 individuals who tested positive for COVID-19 in their series, 775 (21%) had a BMI of 30-34 and 595 (16%) had a BMI of at least 35. Obesity wasn’t a predictor of admission to hospital or the ICU in those over the age of 60 years, but in those younger than 60 years, it was.

Those under age 60 with a BMI of 30-34 were twice as likely to be admitted to hospital (hazard ratio, 2.0; P < .0001) and critical care (HR, 1.8; P = .006), compared with those under age 60 with a BMI less than 30. Likewise, those under age 60 with a BMI of at least 35 were 2.2 (P < .0001) and 3.6 (P < .0001) times more likely to be admitted to acute and critical care.

“Unfortunately, obesity in people [less than] 60 years is a newly identified epidemiologic risk factor which may contribute to increased morbidity rates [with COVID-19] experienced in the U.S.,” they concluded.

And in the other U.S. study, Christopher M. Petrilli, MD, of New York University, and colleagues looked at 4,103 patients with COVID-19 treated between March 1 and April 2, 2020, and followed to April 7.

Just under half of patients (48.7%) were hospitalized, of whom 22.3% required mechanical ventilation and 14.6% died or were discharged to hospice. The research was published on medRxiv, showing that, apart from age, the strongest predictors of hospitalization were BMI greater than 40 (OR, 6.2) and heart failure (OR, 4.3).

“It is notable that the chronic condition with the strongest association with critical illness was obesity, with a substantially higher odds ratio than any cardiovascular or pulmonary disease,” they noted.
 

Inflammation is a possible culprit

Dr. Pattou believes that the culprit behind the increased risk of disease severity seen with obesity in COVID-19 is inflammation, mediated by fibrin deposits in the circulation, which his colleagues have seen on autopsy, and which “block oxygen passage through the blood.”

This may help explain why mechanical ventilation can be less successful in these patients. “The answer is to get rid of this inflammation,” Dr. Pattou observed.

Dr. Petrilli and colleagues also observed that obesity “is well-recognized to be a proinflammatory condition.”

And their findings showed “the importance of inflammatory markers in distinguishing future critical from noncritical illness,” they said, noting that, among these markers, early elevations in C-reactive protein and D-dimer “had the strongest association with mechanical ventilation or mortality.”

Livio Luzi, MD, of IRCCS MultiMedica, Milan, Italy, has previously written on the relationship between influenza and obesity, and discussed in an interview the potential lessons for the COVID-19 pandemic.

“Obesity is characterized by an impairment of immune response and by a low-grade chronic inflammation. Furthermore, obese subjects have an altered dynamic of pulmonary ventilation, with reduced diaphragmatic excursion,” Dr. Luzi said. These factors, alongside others, “may help to explain” the current results, and stress the importance of close monitoring of those with obesity and COVID-19.

Although priority number one lies in controlling the spread of COVID-19, public health researchers are calling attention to the long-term repercussions of the pandemic on children’s health.

School closures could noticeably worsen the epidemic of childhood obesity that already threatens many children in the United States, say Paul Rundle, DrPH, and colleagues from Columbia University Mailman School of Public Health, New York City, in a perspective published online March 30 in Obesity.

“In part, we wrote the perspective to remind people that summer unhealthy weight gain seems to accumulate year to year,” he told Medscape Medical News in an email.

Rundle and colleagues estimate that time spent out of school will double this year because of school closures due to COVID-19. That, along with shelter-in-place orders, will pose challenges both for physical activity and healthy eating among children.

In addition, playgrounds have closed in many areas, and even where parks remain open, social distancing decreases opportunities for exercise. Team sports are on hold, and without physical education taught in schools, many children will not be getting as much active outdoor play as needed.

That’s especially true for children in urban areas, who may find it even more difficult to exercise inside cramped apartments, they add.

As a result, more and more children may turn to sedentary activities, and increased screen time goes hand in hand with childhood overweight and obesity, not just because of the lack of exercise but also because of snacking on unhealthy, empty-calorie foods while glued to the screen.

“We were hoping to get the word out on this issue, do some education or reminding, and at least let people know that this should be something to keep an eye on, among so many other things,” Rundle added.

Excess Eating Because of Stress and Boredom

Jessica Sparks Lilley, MD, director of the Pediatric Diabetes and Lipid Program at the Mississippi Center for Advanced Medicine in Madison, agrees that it is crucial to address these issues.

“Just like adults, children eat in response to emotions, including stress and boredom, and stress levels are high during these uncertain times,” she told Medscape Medical News.

Although both Rundle and Sparks Lilley acknowledged the challenges of finding good solutions at this time, they do offer some tips.

Schools should make physical education and at-home exercise a priority alongside other remote teaching. Physical education teachers could even stream exercise classes to children at home.

Even just walking in the park while maintaining social distancing could be better than nothing, and a brisk walk is probably even better.

Depending on the age of the child, online yoga may also be useful. Even though yoga burns relatively few calories, it incorporates mindfulness training that may be helpful.

“I think focusing on promoting mindful eating as compared to mindless or distracted eating is important. Even in the best of circumstances, it is hard to exercise enough to burn off high energy snacks,” Rundle said.

Additional Stressors From Poverty: Schools Can Help With Meals

Children living in poverty, already the most vulnerable to obesity and related health problems, have additional stressors, add the two experts.

“As more Americans are losing jobs, poverty is a real threat to many of the children I care for. Families living in poverty often rely on processed, high-calorie, low-nutrient foods for survival, because they are inexpensive and shelf-stable,” Sparks Lilley said.

Rundle and colleagues agree: “Our own experiences in supermarkets show...shelves that held...crackers, chips, ramen noodles, soda, sugary cereals, and processed ready-to-eat meals are quite empty. We anticipate that many children will experience higher calorie diets during the pandemic response.”

Similar to how they address food insecurity during summer holidays, school districts have responded by offering grab-and-go meals, Rundle and colleagues note.

To maintain social distancing for people with vulnerable family members, some school districts have also started delivering food using school buses that run along regularly scheduled routes.

Rundle also stresses that farmers’ markets, which often provide foods that appeal to immigrant and ethnic communities, should be considered part of essential food services.

As such, social distancing protocols should be established for them and they should be allowed to stay open, he argues.

“The safety of American children is at stake in many ways. The threat to themselves or their caregivers being infected with COVID-19 is rightly foremost in our concerns,” Sparks Lilley stressed.

“However, there is other fallout to consider. We’ve seen very clearly the need for public health and preventive medicine and can’t let vulnerable children fall through the cracks.”

Rundle agrees. Although it is a “priority” to mitigate the immediate impact of COVID-19, “it is important to consider ways to prevent its long-term effects, including new risks for childhood obesity.”

Rundle and coauthors, as well as Sparks Lilley, have reported no relevant financial relationships.

Although priority number one lies in controlling the spread of COVID-19, public health researchers are calling attention to the long-term repercussions of the pandemic on children’s health.

School closures could noticeably worsen the epidemic of childhood obesity that already threatens many children in the United States, say Paul Rundle, DrPH, and colleagues from Columbia University Mailman School of Public Health, New York City, in a perspective published online March 30 in Obesity.

“In part, we wrote the perspective to remind people that summer unhealthy weight gain seems to accumulate year to year,” he told Medscape Medical News in an email.

Rundle and colleagues estimate that time spent out of school will double this year because of school closures due to COVID-19. That, along with shelter-in-place orders, will pose challenges both for physical activity and healthy eating among children.

In addition, playgrounds have closed in many areas, and even where parks remain open, social distancing decreases opportunities for exercise. Team sports are on hold, and without physical education taught in schools, many children will not be getting as much active outdoor play as needed.

That’s especially true for children in urban areas, who may find it even more difficult to exercise inside cramped apartments, they add.

African Americans are overrepresented among patients who have died as a result of the COVID-19 pandemic, but the current crisis puts a spotlight on long-standing racial disparities in health care and health access in the United States, according to David R. Williams, PhD, a professor of public health at the Harvard T.H. Chan School of Public Health in Boston.

Dr. Williams, a social scientist specializing in the link between race and health, is a professor of African and African American Studies and of Sociology at Harvard. He spoke on the topic of racial disparities amid the COVID-19 pandemic in a teleconference sponsored by the Robert Wood Johnson Foundation.

“Many Americans are shocked” by the higher mortality rates among African American COVID-19 patients, said Dr. Williams. However, data from decades of research show that “black people in America live sicker and shorter lives,” he said.

Keys to the increased mortality among African Americans include an increased prevalence of risk factors, increased risk for exposure to the virus because of socioeconomic factors, and less access to health care if they do become ill, he said.

Many minority individuals work outside the home in areas deemed essential during the pandemic, such as transit, delivery, maintenance, cleaning, and in businesses such as grocery stores, although in general “race continues to matter for health at every level of income and education,” Dr. Williams said.

In addition, social distance guidelines are not realistic for many people in high-density, low-income areas, who often live in shared, multigenerational housing, he said.

Data show that individuals with chronic conditions such as diabetes and cardiovascular disease are more likely to die as a result of COVID-19, and minority populations are more likely to develop these conditions at younger ages, Dr. Williams noted. Access to health care also plays a role. Many minority individuals of lower socioeconomic status are less likely to have health insurance, or if they do, may have Medicaid, which is not consistently accepted, he said. Also, some low-income neighborhoods lack convenient access to primary care and thus to screening services, he noted.

A recent study from the Centers for Disease Control and Prevention’s Morbidity and Mortality Weekly Report cited COVID-NET (the COVID-19 Associated Hospitalization Surveillance Network) as showing that, in their catchment population, “approximately 59% of residents are white, 18% are black, and 14% are Hispanic; however, among 580 hospitalized COVID-19 patients with race/ethnicity data, approximately 45% were white, 33% were black, and 8% were Hispanic, suggesting that black populations might be disproportionately affected by COVID-19,” the researchers said.

“These findings, including the potential impact of both sex and race on COVID-19–associated hospitalization rates, need to be confirmed with additional data,” according to the report.

Collecting racial/ethnic information is not always feasible on the front lines, and many areas still face shortages of ventilators and protective equipment, said Dr. Williams.

“I want to salute the providers on the front lines of this pandemic, many putting their own lives at risk, I want to acknowledge the good that they are doing,” Dr. Williams emphasized. He noted that all of us, himself included, may have conscious or unconscious stereotypes, but the key is to acknowledge the potential for these thoughts and feelings and continue to provide the best care.

“Why is this uniquely important to me? I am an academic cardiologist; I study health care disparities; and I am a black man,” he wrote.

“Even though these data are preliminary and further study is warranted, the pattern is irrefutable: Underrepresented minorities are developing COVID-19 infection more frequently and dying disproportionately,” said Dr. Yancy.

Dr. Williams’ and Dr. Yancy’s comments were supported by an analysis of COVID-19 patient data from several areas of the country conducted by the Washington Post. In that analysis, data showed that several counties with a majority black population showed three times the rate of COVID-19 infections and approximately six times as many deaths compared with counties with a majority of white residents.

“The U.S. has needed a trigger to fully address health care disparities; COVID-19 may be that bellwether event,” said Dr. Yancy. “Certainly, within the broad and powerful economic and legislative engines of the US, there is room to definitively address a scourge even worse than COVID-19: health care disparities. It only takes will. It is time to end the refrain,” he said.

Dr. Williams had no financial conflicts to disclose. Dr. Yancy had no financial conflicts to disclose.

Children with overweight or obese body mass index measures at preschool age were significantly more likely than were normal weight children to suffer upper- and lower-limb fractures before age 15 years, according to data from almost 470,000 children.

Previous studies of adults have shown associations between obesity and fractures, but the impact of higher BMI at preschool age on fracture incidence later in childhood has not been explored, according to Jennifer C.E. Lane, MD, of the University of Oxford (England), and colleagues. “A focused study of the association between preschool obesity and fracture risk offers the opportunity to better understand the impact of obesity in early life,” they wrote in the Journal of Bone and Mineral Research.

The researchers reviewed data from 466,997 children at 296 primary care centers using the Information System for Research in Primary Care, a Spanish national database, for the years 2003-2013. The children were assessed starting at age 4 years and followed until age 15 years or until they left the region or died, or until the study period ended, on Dec. 31, 2016. The average follow-up time was 4.9 years, and 49% of the children were girls. BMI categories were determined via the World Health Organization growth standards for calculating age- and sex-specific BMI z scores, and the categories were defined as underweight (< −2 BMI z score), normal weight (−2 to +2 BMI z score), overweight (> +2 BMI z score), and obese (> +3 BMI z score).

Overall, children with a BMI in the overweight or obese ranges at first assessment were significantly more likely than were their normal weight counterparts to suffer lower-limb fractures (adjusted hazard ratios, 1.42 and 1.74, respectively) and upper-limb fractures (aHRs, 1.10 and 1.19, respectively) during the follow-up period.

The total incidence of fractures during childhood for those in the study who were underweight, normal weight, overweight, or obese, was 9.20%, 10.06%, 11.28%, and 13.05% respectively.

In a secondary analysis, fracture risk varied by anatomic location and reflected previous findings showing an increased risk of distal limb fractures associated with high BMI, the researchers said.

The findings were limited by several factors, including the smaller-than-average proportion of children with overweight or obese BMI measures, the imprecise nature of the BMI z score as a predictor of obesity in children, and the lack of data on sports, medical issues, and general activity levels, the researchers noted.

However, the results were strengthened by the population-based sample and long-term follow-up, and the work “suggests that interventions to treat obesity in early childhood could have benefits for the primary or secondary prevention of fractures later in childhood, especially in the prevention of fractures within the forearm and hand or foot and ankle,” the authors concluded.

The study was supported in part by the NIHR Biomedical Research Centre, Oxford, and La Marató de TV3 Foundation. Dr. Lane disclosed funding from a Versus Arthritis Clinical Research Fellowship but had no financial conflicts to disclose. Some authors reported relationships with numerous pharmaceutical firms.

Overall, children with a BMI in the overweight or obese ranges at first assessment were significantly more likely than were their normal weight counterparts to suffer lower-limb fractures (adjusted hazard ratios, 1.42 and 1.74, respectively) and upper-limb fractures (aHRs, 1.10 and 1.19, respectively) during the follow-up period.

The total incidence of fractures during childhood for those in the study who were underweight, normal weight, overweight, or obese, was 9.20%, 10.06%, 11.28%, and 13.05% respectively.

In a secondary analysis, fracture risk varied by anatomic location and reflected previous findings showing an increased risk of distal limb fractures associated with high BMI, the researchers said.

The findings were limited by several factors, including the smaller-than-average proportion of children with overweight or obese BMI measures, the imprecise nature of the BMI z score as a predictor of obesity in children, and the lack of data on sports, medical issues, and general activity levels, the researchers noted.

However, the results were strengthened by the population-based sample and long-term follow-up, and the work “suggests that interventions to treat obesity in early childhood could have benefits for the primary or secondary prevention of fractures later in childhood, especially in the prevention of fractures within the forearm and hand or foot and ankle,” the authors concluded.

The study was supported in part by the NIHR Biomedical Research Centre, Oxford, and La Marató de TV3 Foundation. Dr. Lane disclosed funding from a Versus Arthritis Clinical Research Fellowship but had no financial conflicts to disclose. Some authors reported relationships with numerous pharmaceutical firms.

I would like to provide an update to my article, “10 proven strategies to help patients maintain weight loss” (J Fam Pract. 2020;69:20-25), which mentioned lorcaserin as one of several medications approved by the US Food and Drug Administration (FDA) for long-term use in weight maintenance. On February 13, 2020, the FDA requested that the manufacturer of Belviq and Belviq XR (lorcaserin), Eisai Inc., voluntarily withdraw the weight-loss drug from the US market because a safety clinical trial demonstrated an increased occurrence of cancer. Eisai Inc. has submitted a request to voluntarily withdraw the drug. The FDA has advised patients to stop taking lorcaserin and talk to their health care provider about alternative weight-loss medicines and weight management programs.

Participants who had higher levels of fitness when beginning a behavioral weight-loss intervention kept off more weight over the course of an 18-month study, compared with those with lower levels of fitness at baseline.

Those with higher baseline fitness also were able to achieve higher levels of moderate to vigorous physical activity at the 18-month mark, Adnin Zaman, MD, said during a virtual news conference held by the Endocrine Society. The study had been slated for presentation during ENDO 2020, the society's annual meeting, which was canceled because of the COVID-19 pandemic.

“Our study really comes from an observation that we often see significant variability in how much weight participants lose during a behavioral weight-loss intervention study, said Dr. Zaman, an endocrinology research fellow at the University of Colorado at Denver, Aurora.

She and her colleagues wanted to look at baseline cardiovascular fitness as an individual-specific factor that could affect how much weight people lost when participating in a behavioral intervention.

“Very little is known about how cardiovascular fitness affects [people’s] ability to lose weight [or] to adhere to high levels of physical activity, which is a very common recommendation during a program for both weight loss and weight-loss maintenance,” she added.

Dr. Zaman and colleagues conducted a secondary analysis of data from an 18-month trial of behavioral interventions for weight loss. The trial randomized 170 participants 1:1 to receive either concurrent exercise and a dietary behavior modification intervention or sequential dietary and exercise interventions.

The 85 participants in the concurrent intervention arm received 18 months of combined dietary modifications (calorie-restricted diet and group-based behavioral support) and exercise (supervised for the first 6 months of the study, unsupervised for the final 12). Those participating in the sequential intervention arm received a diet-only intervention during the first 6 months of the study, after which supervised exercise was added to the dietary intervention for 6 months, followed by a final 6 months of unsupervised exercise.

Participants in both study arms worked up to 300 minutes a week of moderate to vigorous physical activity in the supervised exercise phase.

For the secondary analysis, Dr. Zaman and colleagues looked only at the 60 participants who received concurrent diet and exercise interventions and who completed the full 18-month study. The mean age in that group was 40 years, mean baseline body mass index (BMI) was 34.6 kg/m², and 80% of participants in the group were women.

Cardiovascular fitness as measured by VO_2max was assessed at baseline using a graded exercise test. Participants were designated as having either “very poor” or “poor or better” cardiovascular fitness (20 and 40 participants, respectively).

Participants in the original trial were inactive at baseline and had a BMI range of 27-42 kg/m². Among the subset of participants studied by Dr. Zaman and colleagues, those who were in the poor or better fitness category actually weighed less at baseline and had a lower BMI, compared with those in the very poor group (33.7 vs. 36.2, respectively), she said. Mean VO_2max for those with very poor fitness was 22.5 mL/kg per minute, compared with 25.6 mL/kg per minute for those with poor or better fitness.

“Despite those differences, it is interesting to note that, during the supervised exercise portion of the study ... everyone lost pretty much the same amount of weight in the first 6 months,” said Dr. Zaman. At the 6-month mark, those with very poor fitness had lost 9.2 kg (20.3 pounds), and those with poor or better fitness had lost 9.1 kg (20.1 pounds). However, weight regain was less likely in those with poor or better fitness, and those participants had a net loss of weight from baseline of 8.2 kg (18.1 pounds), compared with 4.4 kg (9.7 pounds) for those with very poor fitness.

Those with poor or better fitness were able to sustain a 33-minute bout of moderate to vigorous physical activity at baseline, whereas those with very poor fitness could achieve only about half of that. The difference in achievable physical activity between the two groups persisted throughout the study, with a peak at the 6-month mark, at about 60 minutes for the more fit participants and 38 minutes for those in the poor fitness group. By the end of the study, the less-fit participants achieved about 24 minutes of activity, whereas those who were more fit could sustain about 42 minutes of moderate to vigorous physical activity.

Physical activity levels were measured with a validated, wrist-worn device during a 1-week period at baseline and again at study months 6, 12, and 18.

Dr. Zaman noted that baseline weight may have confounded fitness categorization, because VO_2max includes body weight in its calculations. A newer method of calculating cardiorespiratory fitness that scales VO_2max to body weight may help minimize this potential confounder.

The investigators reported no outside sources of funding and reported that they had no financial conflicts of interest.

The research will be published in a special supplemental issue of the Journal of the Endocrine Society. In addition to a series of news conferences on March 30-31, the society will host ENDO Online 2020 during June 8-22, which will present programming for clinicians and researchers.
