Values are linear regression coefficients β ± SE. CA is measured with Adipcent, DQ is measured with HEI, and DS is measured with CES-D. *P < 0.05 for null hypothesis that β = 0 in the multiple linear regression model. All analyses accounted for sampling design complexity by including population weights. Each model is adjusted for v1 age, marital status (unmarried = 0 compared with married = 1), smoking (never = 0 compared with former = 1 or current = 2), and illicit drug use status (never = 0 compared with former = 1 or current = 2) and the inverse Mills ratio. Adipcent, central adiposity factor score derived from a principal components analysis of waist circumference and trunk fat (kg); CA, central adiposity; CES-D, Center for Epidemiologic Studies–Depression; DQ, dietary quality; DS, depressive symptoms; HANDLS, Healthy Aging in Neighborhoods of Diversity across the Life Span; HEI, Healthy Eating Index; m, mean across visits; SES, socioeconomic status (z score derived from a principal components analysis of education in years and poverty status); v1, visit 1 or baseline; v2, visit 2 or follow-up.
P-interaction < 0.05 for null hypothesis of no difference by sex and race in the effect of SES on the outcome variable, based on a model with race × sex and SES × race × sex entered in addition to the main effects and the potential confounders. “White women” is the referent category being compared with all other sex and race groups.
