Title: Weight Management Demonstration Project: Healthy Eating and Active Living in TRICARE Households
Brief Summary: The study investigated the effectiveness and cost-effectiveness of a cognitive and behavioral weight management program, complemented by an interactive Web site and brief telephone coaching, implemented among TRICARE non-active-duty beneficiaries.

A total of 1,755 participants from four Midwestern states were randomized to one of three randomized controlled trial groups with increasing intervention intensity: mailed material and basic Web access (RCT1), plus an interactive Web site (RCT2), plus brief phone- and Web-based coaching support from health lifestyle coaches (RCT3). The study assessed changes in participants' weight, blood pressure, diet, and physical activity from baseline to 6, 12, and 15 to 18 months. Analyses estimated overall cost savings and calculated the cost-effectiveness ratio of each randomized controlled trial compared with a "do-nothing" alternative as the cost per quality-adjusted life year.
