Summary:
More Americans weighed in as obese during the first year of the
COVID-19 pandemic than in the previous year. A new study presents
evidence from a large, nationally representative survey that
documents this trend and helps to explain behavior changes that
led to widespread weight gain in 2020.



FULL STORY ==========================================================================
More Americans weighed in as obese during the first year of the COVID-19 pandemic than in the previous year. Anew study in the American Journal
of Preventive Medicine, published by Elsevier, presents evidence from a
large, nationally representative survey that documents this trend and
helps to explain behavior changes that led to widespread weight gain
in 2020.


========================================================================== "Previous studies present evidence that intra-pandemic changes in risky
dietary and other health-related behaviors likely contributed to the
rapid rise in body weight during this period. Adults who reported weight
gain also reported more frequent snacking and alcohol intake; increased
eating in response to sight, smell, and stress; and decreased physical activity," explained lead investigator, Brandon J. Restrepo, PhD, US
Department of Agriculture, Economic Research Service, Food Economics
Division -- Diet, Safety and Health Economics Branch, Washington, DC, USA.

Adult obesity in the US was elevated and trending upward prior to the
COVID-19 pandemic. While several studies have reported on small and
relatively homogenous online surveys that track weight gain in the US
adult population during the initial pandemic period, this study is the
first to use data from the Behavioral Risk Factor Surveillance System
(BRFSS), a larger, nationally representative survey of the US adult
population. It contains data on health outcomes, health-related risk
behaviors, preventive services, and chronic medical conditions.

To estimate the overall changes in adult obesity prevalence and four
obesity- related risk factors during the COVID-19 pandemic, the analysis
of the BRFSS data employed linear regression models that control for age,
sex, race/ ethnicity, education, household income, marital status, number
of children, survey year indicators, and state of residence indicators.

According to the analysis of more than 3.5 million US adults (aged 20 and older) from the 2011-2020 BRFSS, obesity was 3% more prevalent during
the year beginning March 2020, compared with the 2019 to pre-pandemic
2020 period. The study also 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.

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

"Our results, which are broadly consistent with what prior studies
have found using smaller and less representative samples, contribute
additional insights that can serve to inform policymakers about the state
of the US adult obesity epidemic and obesity-related risk factors,"
noted Dr. Restrepo, adding, "Because obesity affects some adults more
than others, it would be helpful to further explore the changes in the
rates of adult obesity by demographic subgroup and socioeconomic status."
