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