BMC Public Health 2016 16 732 BACKGROUND: Because residents of the southeastern United States experience disproportionally high rates of cardiovascular disease (CVD), it is important to develop effective lifestyle interventions for this population. METHODS: The primary objective was to develop and evaluate a dietary, physical activity (PA) and weight loss intervention for residents of the southeastern US. The intervention, given in eastern North Carolina, was evaluated in a 2 year prospective cohort study with an embedded randomized controlled trial (RCT) of a weight loss maintenance intervention. The intervention included: Phase I (months 1-6), individually-tailored intervention promoting a Mediterranean-style dietary pattern and increased walking; Phase II (months 7-12), option of a 16-week weight loss intervention for those with BMI ≥ 25 kg/m(2) offered in 2 formats (16 weekly group sessions or 5 group sessions and 10 phone calls) or a lifestyle maintenance intervention; and Phase III (months 13-24), weight loss maintenance RCT for those losing ≥ 8 lb with all other participants receiving a lifestyle maintenance intervention. Change in diet and PA behaviors, CVD risk factors, and weight were assessed at 6, 12, and 24 month follow-up. RESULTS: Baseline characteristics (N = 339) were: 260 (77 %) females, 219 (65 %) African Americans, mean age 56 years, and mean body mass index 36 kg/m(2). In Phase I, among 251 (74 %) that returned for 6 month follow-up, there were substantial improvements in diet score (4.3 units [95 % CI 3.7 to 5.0]), walking (64 min/week [19 to 109]), and systolic blood pressure (-6.4 mmHg [-8.7 to -4.1]) that were generally maintained through 24 month follow-up. In Phase II, 138 (57 group only, 81 group/phone) chose the weight loss intervention and at 12 months, weight change was: -3.1 kg (-4.9 to -1.3) for group (N = 50) and -2.1 kg (-3.2 to -1.0) for group/phone combination (N = 75). In Phase III, 27 participants took part in the RCT. At 24 months, weight loss was -2.1 kg (-4.3 to 0.0) for group (N = 51) and -1.1 kg (-2.7 to 0.4) for combination (N = 72). Outcomes for African American and whites were similar. CONCLUSIONS: The intervention yielded substantial improvement in diet, PA, and blood pressure, but weight loss was modest.

Prev Med 2009 49 (5) 390-5 OBJECTIVE: Assess the cost-effectiveness of a 16-week weight loss intervention (Weight-Wise) for low-income midlife women. METHOD: A randomized controlled trial conducted in North Carolina in 2007 tested a weight loss intervention among 143 women (40-64 years old, mean BMI=35.1 kg/m(2)). Women were randomized to one of two arms-special intervention (n=72) and a wait-listed control group (n=71). Effectiveness measures included changes in weight, systolic and diastolic blood pressure, total cholesterol, and HDL cholesterol. Cost-effectiveness measures calculated life years gained (LYG) from changes in weight, based on excess years life lost (YLL) algorithm. RESULTS: Intervention participants had statistically significant decreases in weight (kg) (-4.4 95% CI=-5.6, -3.2) and in systolic blood pressure (-6.2 mm Hg, 95% CI=-10.6, -1.7) compared to controls. Total cost of conducting Weight-Wise was $17,403, and the cost per participant in intervention group was $242. The incremental cost per life year gained (discounted) from a decrease in obesity was $1862. CONCLUSION: Our results suggest the Weight-Wise intervention may be a cost-effective approach to improving the health of low-income women. |
