Analyses was based on Poisson regression modeling, considering the potential interaction of age groupings with or without disease burden (defined as the presence of obesity, diabetes, or hypertension); covariates were race/ethnicity, sex, education, income. Ages 18—44 and Non-Hispanic White served as referents.
