Prevalence of Obesity and Severe Obesity Among Adults: United States, 2017-2018.
Level 4 - case-series / case-control
Cross-sectional national surveillance survey (CEBM level 4 for descriptive/prevalence epidemiology)
What was done
National cross-sectional survey data from the United States was analyzed to estimate the prevalence of obesity and severe obesity among adults aged 20 and older for 2017–2018 across sex, age, and race/Hispanic origin subgroups, as well as multi-year trends from 1999–2000 through 2017–2018.
What was found
The abstract reports no numerical estimates, percentages, or statistical comparisons for the 2017–2018 data or the overall trend through 2018. It only notes that a significantly increasing trend in obesity had previously been observed from 1999–2000 through 2015–2016.
Why it matters
It provides updated national surveillance metrics for tracking adult obesity and severe obesity burden across demographic groups in the United States.
Limits
The abstract omits sample size, response rates, and all numeric prevalence figures. The cross-sectional design cannot evaluate causal factors contributing to changing obesity rates.
