Adherence
Dietary improvements in the US between 1999 and 2012 were not uniform across all demographic groups, with significant disparities persisting or worsening for non-Hispanic Black and Mexican American adults, as well as those with lower income levels.
Public health initiatives must target specific demographic groups with tailored interventions, as general dietary improvements have not reached all communities equally.
GoodQualifiesHIGH confidence
Disparities in diet quality were observed by race/ethnicity, education, and income level; for example, the estimated percentage of non-Hispanic white adults with a poor diet significantly declined (53.9% to 42.8%), whereas similar improvements were not observed for non-Hispanic black or Mexican American adults.
Why this rating
Large, nationally representative data allows for robust subgroup analysis.
