Table 1 shows population characteristics of the stage 1 and 2 samples. Mean (SD) age and the proportion female were 48 (18.7) years and 53.5% in Stage 1 and 50 (19.5) years and 51.9% in Stage 2, respectively. The mean BMI was 28.4 kg/m2 in both Stages. The Stage 1 samples included more Mexican American and other Hispanic and were less educated than the Stage 2 samples. Participants in the Stage 1 had lower HDL (53.0 vs. 54.7 mg/dL) and higher triglycerides (150.2 vs. 140.0 mg/dL) than those in the Stage 2. Total cholesterol was highly correlated with LDL (Spearman correlation coefficient (rho) = 0.86) but modestly correlated with HDL (rho = 0.16) and triglycerides (rho = 0.37) (Table S2). HDL was inversely correlated with triglycerides (rho = –0.42).
