[BDSP. Notice produite par INIST-CNRS l9rR0xEp. Diffusion soumise à autorisation]. Objectives. We examined whether adding behavioral weight loss strategies could improve the outcomes of a community weight loss campaign. Methods. Shape Up RI is a 12-week, online, team-based program for health improvement in Rhode Island. In study 1, we randomly assigned participants to the standard Shape Up RI program or to the program plus video lessons on weight loss. In study 2, we randomly assigned participants to the standard program or to the program plus video lessons ; daily self-monitoring of weight, eating, and exercise ; and computer-generated feedback. Results. Adding video lessons alone (study 1) did not result in significantly improved weight loss (2.0+/-2.8 kg vs 1.4+/-2.9 kg ; P=15). However, when the video lessons were supplemented with self-monitoring and feedback (study 2), the average weight loss more than doubled (3.5+/-3.8 kg vs 1.4+/-2.7 kg ; P<. and the proportion of individuals achieving a weight loss or more tripled vs p participants in study submitted self-monitoring records on days adherence was significantly related to outcome. conclusions. adding behavioral strategies community campaigns may improve outcomes with minimal additional cost.>
