The benefits of regular physical activity are widely recognized, however the large majority of overweight minority women do not engage in this behavior. The purpose of this study is to explore the relationships between exercise, self‐efficacy, and lipids in low income, tri‐ethnic mothers who participated in an 8 wk weight loss intervention. Demographics, anthropometrics, physical activity via pedometers, self‐efficacy, and serum lipids were measured at wk 0 and 8. Participants had a decrease in weight (181 vs. 174) and % body fat (41 vs. 39) (p<0.001) and an increase in pedometer steps (179 vs. 298) and self‐efficacy scale scores (28 vs. 31) at wk 8. Improvement in activity, as determined by pedometer steps, was positively linked to concern about losing weight, living with partners, and breastfeeding (p<0.05) at post intervention. Pedometer steps at wk 8 were associated inversely with BMI (r= −.420), waist circumference (r=−.459), and % body fat (r= −.438) (p<0.01), and positively with weight loss (r = .548, p<0.001). Self‐efficacy was related with greater pedometer steps (r= .378) and lower % body fat (r= −.351), waist circumference (r= −.402), LDL (r= −.421) (p<0.05), and total cholesterol (r= −.461, p<0.01). Thus, physical activity measured via pedometers and its self‐efficacy were indicators of successful weight loss in low income women in early postpartum. Supported by TX Coordinating Board # UTA00‐377
