Characteristics of the cohort of African American women recruited from randomly selected households in inner city and suburban St. Louis, Missouri, USA.

There were no significant differences in age, blood pressure, BMI, waist circumference or serum hormone levels between inner city and suburban dwelling women

SBP = systolic blood pressure; DBP = diastolic blood pressure; BMI = body mass index; T = testosterone; SHBG = sex hormone-binding globulin; FAI = free androgen index; DHEAS = dehydroepiandrosterone sulfate; E2 = oestradiol.

^aAnnual household income has been reported as a categorical variable (i.e., % ≤ 20K for city and for suburbs).
