Abstract

ObjectiveAssess the cost-effectiveness of a 16-week weight loss intervention (Weight-Wise) for low-income midlife women.MethodA 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/m2). 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.ResultsIntervention 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.ConclusionOur results suggest the Weight-Wise intervention may be a cost-effective approach to improving the health of low-income women.
