Low first tertile; median second tertile; high third tertile; CI confidence interval; disc discrimination. Model 1 covariates: Individual discrimination score (by tertile), age, sex; Model 2 covariates: Model 1 covariates + education (<HS/HS–some college/college graduate); Model 3 covariates: Model 2 covariates + nutrition (poor heath/other), physical activity (poor/intermediate/ideal health), smoking status (current smoker/other), alcohol consumption (number of drinks per week).
