Trends of Obesity in Early Adulthood and Later Adulthood Across 196 Countries and Territories, 1990–2022
Study context
- Population
- Adults in 196 countries/territories, 1990–2022196 countries/territories
- Exposure
- Obesity in early adulthood vs later adulthood
- Outcome
- Obesity prevalence: magnitude of change between baseline (1990-1994) and endline (2018-2022) and average annual percent change
- Follow-up
- 1990-1994 to 2018-2022
Methodological detailssegmented regression, NCD Risk Factor Collaboration dataset
- Segmented regression
- NCD Risk Factor Collaboration dataset
Main finding
As reported in the abstract
Obesity prevalence change
Magnitude of prevalence increase higher in later than early adulthood (countries/territories)
134
Prevalence increased faster in early than later adulthood (countries/territories)
168
Observational data: associations, not effects.
Further findings
Prevalence change by sex, income and baseline prevalence
- Women and countries/territories with higher income and baseline obesity prevalence had larger increases in prevalence magnitude
- Rate of increase more rapid in men and countries/territories with lower income and baseline prevalence
