Prevalence Ratio (PR) and 95% Confidence Interval (CI) of Peripheral Arterial Disease (PAD) per Standard Deviation Increase in Percent of European Ancestry (PEA) among African Americans: The Jackson Heart Study (2000–2004)

PEA	PR (95% CI)	P value
Model1: Demographic	0.90 (0.82, 0.99)	0.036
Model2: Traditional CVD factors	0.90 (0.82, 0.99)	0.024
Model3: SES & Psychosocial factors	0.92 (0.83, 1.01)	0.082
Model4: Fully adjusted	0.91 (0.82, 1.00)	0.046

PAD defined as ABI <=0.99

Standard deviation, 9.0%

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; PAD: peripheral arterial disease; ABI: ankle-brachial index; hsCRP: high sensitivity C – reactive protein.
