We assessed the associations among age, education, and baseline clinical characteristics and sex–race groups with simple linear regression and among the 4 optimal HLCs and sex–race groups with chi‐square tests. BMI indicates body mass index; CARDIA, Coronary Artery Risk Development in Young Adults; DBP, diastolic blood pressure; Glu, glucose; HLC, healthy lifestyle component; PA, physical activity; SBP, systolic blood pressure; TC, total cholesterol.
