Objectives. We determined the efficacy and cost-effectiveness of adding an evidence-based Internet behavioral weight loss intervention alone or combined with optional group sessions to ShapeUp Rhode Island 2011 (SURI), a 3-month statewide wellness campaign.
Methods. We randomized participants (n = 230; body mass index = 34.3 +/- 66.8 kg/m(2); 84% female) to the standard SURI program (S) or to 1 of 2 enhanced programs: SURI plus Internet behavioral program (SI) or SI plus optional group sessions (SIG). The primary outcome was weight loss at the end of the 3-month program.
Results. Weight losses differed among all 3 conditions (S: 1.1%+/- 60.9%; SI: 4.2%+/- 60.6%; SIG: 6.1%+/- 60.6%; Ps <= 04). Both SI and SIG increased the percentage of individuals who achieved a 5% weight loss (SI: 42%; SIG: 54%; S: 7%; Ps <.001). Cost per kilogram of weight loss was similar for S ($ 39) and SI ($ 35); both were lower than SIG ($ 114).
Conclusions. Although weight losses were greatest at the end of SURI with optional group sessions, the addition of an Internet behavioral program was the most cost-effective method to enhance weight losses.
