Model1: Adjusted for demographic: age and gender;

Model2: Adjusted for model 1 and traditional CVD risk factors: BMI, current smoking, diabetes, hypertension, fasting plasma glucose, triglycerides, LDL cholesterol, HDL cholesterol, and hsCRP;

Model3: Adjusted for model 1 and SES & Psychosocial factors: household annual income, education, perceived global stress, and every day and lifetime discrimination;

Model4: Adjusted for all the covariates

PEA: percent of European ancestry; cCIMT: common intima-media thickness; CAC: coronary artery calcium; AAC: abdominal aortic calcification: hsCRP: high sensitivity C – reactive protein;
