Informed consent was obtained from 44 African American (AA), 45 Native American (NA), and 46 Caucasian (CA) women who volunteered to be in the Cross-Cultural Activity Participation Study (CAPS). The aim of CAPS was to develop physical activity surveys for diverse populations of women.11,13,16,17 CAPS inclusion criteria were self-reported: AA, NA, or CA ethnicity, absence of symptomatic disease, and the absence of conditions that would preclude daily physical activity. Interview-based health histories, body mass index (BMI, kg/m2), waist girth (cm), and resting blood pressure measures have been described.11,13,16,1
