The efficacy and cost-effectiveness of a community weight management intervention: A randomized controlled trial of the health weight management demonstration

► We assess a cognitive-behavioral weight management program in 1755 TRICARE adults. ► We compare a basic program (RCT1), plus interactive web (RCT2), plus brief phone coaching (RCT3). ► All groups experience significant weight lost after 12 and 18 months. ► Participants increase physical activity and reduce high blood pressure. ► The program is cost-effective (e.g., $900-$1,000 per QALY in RCT 1&2; $1,900 per QALY in RCT3).
