Table 2.
Age- and sex-adjusted prevalence of obesity, diabetes, and hypertension across participant characteristics. a Adjusted for age (linear and squared term) only. b Adjusted for sex only. c Adjusted for age (linear and squared term) and sex. Prevalence was computed as predicted probabilities from the multivariable logistic regression models. Absolute difference in prevalence was computed as the average marginal effect relative to the reference category indicated. Obesity was defined as body mass index of ≥30 kg/m2. Hypertension was defined as ≥140/90 mmHg or self-report of diagnosis or self-reported use of anti-hypertension medication. Diabetes was defined as HbA1c ≥6.5% or self-report of diagnosis. All estimates are survey weighted and account for survey design. CI = confidence interval. Ref = reference category.
