The Obesity Epidemic: Biology and Environment Explained
Examine the multifaceted causes of the obesity epidemic, focusing on biological and environmental aspects.
The exact change
As of 2020, 42.4% of American adults have obesity.
Based on the 2017-2018 NHANES survey cycle (published 2020), 42.4% of American adults have obesity.
Why this is better
The 42.4% obesity-prevalence figure was correctly cited from the CDC/NCHS NHANES data, but the article mislabeled it as "as of 2020" when 2020 was only the year the report was published. The actual measurement period was the 2017-2018 survey cycle. Fixed in the body (2 mentions), the excerpt, and the FAQ answer about why obesity increased since 1980.
