Adherence
As national GDP per capita increases, the prevalence of overweight and obesity shifts from being concentrated in the wealthiest population deciles to the poorest deciles, driven by rising obesity rates among the poor rather than declining rates among the wealthy.
Public health policy in developing nations must anticipate that obesity will increasingly become a disease of poverty, not wealth. Interventions should target the poor, focusing on affordable healthy food access and physical activity opportunities, rather than assuming the wealthy are the primary at-risk group.
Our findings indicate that as countries develop economically, overweight prevalence increased substantially among the poorest and stayed mostly unchanged among the wealthiest.
Why this rating
Large sample size (2.24 million respondents) across 103 countries using standardized surveys, though limited by cross-sectional design and self-reported data in some subsets.
