The association between obesity and income or educational level is complex and differs by sex and race/ethnicity.

• Overall, men and women with college degrees had lower obesity prevalence compared with those with less education.
• By race/ethnicity, the same obesity and education pattern was seen among non-Hispanic white, non-Hispanic black, and Hispanic women, and also among non-Hispanic white men, although the differences were not all statistically significant. Although the difference was not statistically significant among non-Hispanic black men, obesity prevalence increased with educational attainment. Among non-Hispanic Asian women and men and Hispanic men there were no differences in obesity prevalence by education level.
• Among men, obesity prevalence was lower in the lowest and highest income groups compared with the middle income group. This pattern was seen among non-Hispanic white and Hispanic men. Obesity prevalence was higher in the highest income group than in the lowest income group among non-Hispanic black men.
• Among women, obesity prevalence was lower in the highest income group than in the middle and lowest income groups. This pattern was observed among non-Hispanic white, non-Hispanic Asian, and Hispanic women. Among non-Hispanic black women, there was no difference in obesity prevalence by income.
