Estimated mean^a of neighborhood supermarkets and convenience store densities^b by 4 classes^c of longitudinal neighborhood SES residents characteristics: the Coronary Artery Risk Development in Young Adults (CARDIA) Study, 1985-2006.

^aDerived from latent class analysis using Mplus version 7(Muthen LK and BO 2010) of Census tract-level data from exam years 0, 7, 10, 15, and 20: percent race white, percent education <HS, percent poverty (below 150% FPL), percent unemployed, percent professional/management occupation, median income, percent vacant housing, aggregate housing value, percent owner occupied, median rent. Time trends were derived from class-specific multivariable random effects regression models that included population density wi hin tract, a random effect for each participant, and year.

^bCounts of Dunn & Bradstreet food resources within Euclidean 3km buffer per 10 km local and secondary roadways.

^cMultivariable random effects regressions modeling each neighborhood food resource as function of class indicators (referent is stable high neighborhood SES residents) , exam year (continuous), interaction of class indicators by exam year, population density, and a random effect for each participant.
