M= mean; SE= standard error; HRQOL = health related quality of life. HRQOL numbers represent subscale scores (from 0 to 100) on the RAND 36-Item Health Survey. Body mass index scores ≥30 were used to classify African American, Hispanic, and white women as obese; whereas, scores of 25≥ were used for Asian Americans. The obesity cut-off point for Asians is based on recent recommendations from the World Health Organization.22–24 The physical health subscale represents the mean score for subscales of physical function, role-physical functioning, pain, and general health. Similarly, the mental health subscale represents the mean score for subscales of vitality, emotional role functioning, social function, and mental health.
