CONTEXT: Menopausal-related weight gain and increased waist circumference have major cardiovascular health implications for older women. The efficacy of a dietary and physical activity lifestyle intervention to prevent weight gain and elevations in cardiovascular disease (CVD) risk factors from the peri- to postmenopause is unknown. OBJECTIVE: To report the 54-month results of a lifestyle dietary and physical activity program on weight, body composition, physical activity, diet, and other CVD risk factors. DESIGN: Data are from a 5-year randomized clinical trial known as the Women's Healthy Lifestyle Project, conducted from 1992 to 1999. PARTICIPANTS: 535 healthy, premenopausal women ages 44 to 50 at study entry enrolled into the trial. INTERVENTION: Participants were randomly assigned to either a lifestyle intervention group receiving a 5-year behavioral dietary and physical activity program or to an assessment-only control group. The lifestyle intervention group was given modest weight loss goals (5-15 lb, or approximately 2.3-6.8 kg) to prevent subsequent gain above baseline weight by the end of the trial. To achieve weight loss and lower low-density lipoprotein cholesterol levels, intervention participants followed an eating pattern consisting of 1,300 kcal/day (25% total fat, 7% saturated fat, 100 mg of dietary cholesterol) and increased their physical activity expenditure (1,000-1,500 kcal/week). MAIN OUTCOME MEASURES: Regarding weight gain prevention, 55% (136/246) of intervention participants were at or below baseline weight compared with 26% (68/261) of controls after 4.5 years, chi2(2, N = 507) =45.0, p <.001. The mean weight change in the intervention group was 0.1 kg below baseline (SD = 5.2 kg) compared with an average gain of 2.4 kg (SD = 4.9 kg) observed in the control group. Waist circumference also significantly decreased more in the intervention group compared with controls (M = -2.9 cm, SD = 5.3 vs. M = -0.5 cm, SD = 5.6, p <.001). Moreover, participants in the lifestyle intervention group were consistently more physically active and reported eating fewer calories and less fat than controls. Long-term adherence to physical activity and a low-fat eating pattern was associated with better weight maintenance. CONCLUSIONS: In healthy women, weight gain and increased waist circumference during the peri- to postmenopause can be prevented with a long-term lifestyle dietary and physical activity intervention.
