What’s skinny on those pandemic pounds? New study sheds light on weight gain during COVID-19 quarantine

More Americans were overweight during the first year of the COVID-19 pandemic than in the previous year. new study in American Journal of Preventive MedicinePublished by Elsevier, presents evidence from a large, nationally representative survey that documents this trend and helps explain the behavioral changes that led to widespread weight gain in 2020.

“Previous studies have offered evidence that inter-epidemic changes in risky diets and other health-related behaviors contributed to the rapid increase in body weight during this period. Adults who reported weight gain also reported more frequent reported snacking and alcohol intake; increased food sight, smell, and stress in response to stress; and decreased physical activity,” principal investigator, Brandon J. Restrepo, PhD, U.S. Department of Agriculture, Economic Research Service, Food Economics Division – Diet, Safety and Health Economics Branch, Washington, DC, explained. America.

Adult obesity in the US was on the rise and trending upward before the COVID-19 pandemic. While many studies have reported on small and relatively homogenous online surveys that track weight gain in the US adult population during the early epidemic period, this study is the first to use data from the Behavioral Risk Factor Surveillance System (BRFSS), Which is a big, big one at the national level. Representative survey of the US adult population. This includes data on health outcomes, health-related risk behaviours, preventive services and chronic medical conditions.

To estimate the prevalence of adult obesity and the overall change in the four obesity-related risk factors during the COVID-19 pandemic, the analysis of BRFSS data employed linear regression models that measured age, gender, race/ethnicity, education, household income, Control for marriage. Status, number of children, survey year indicator and residence status indicator.

Obesity was 3% more prevalent during the year starting March 2020 than in the pre-pandemic 2020 period from 2019, according to an analysis of more than 3.5 million US adults (aged 20 and older) from the 2011-2020 BRFSS . The study found statistically significant changes among US adults in four obesity-related risk factors during the COVID-19 pandemic: exercise participation, sleep duration, alcohol consumption and cigarette smoking.

Whereas exercise participation and sleep duration were 4.4% and 1.5% higher, respectively, the number of days on which alcohol was consumed was 2.7% higher and the prevalence of cigarette smoking was lower by 4%. The overall increase in exercise and sleep was not enough to offset the effect of other behaviors, resulting in an average increase of 0.6% in body mass index during the COVID-19 pandemic. Although smoking cessation is a healthy step, it has been known to lead to some weight gain.

“Our results, which are broadly consistent with those of prior studies using smaller and less representative samples, contribute additional insights that can inform policy makers about the state of the US adult obesity epidemic and obesity-related risk factors.” can work to do,” Dr. “Since obesity affects some adults more than others, it would be helpful to explore changes in adult obesity rates by demographic subgroup and socioeconomic status,” says Restrepo.
