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 < .01), and the proportion of individuals achieving a weight loss of 5% or more tripled (40.5% vs 13.2%; P < .01). Participants in study 2 submitted self-monitoring records on 78% of days, and adherence was significantly related to outcome.
CONCLUSIONS
Adding behavioral strategies to community campaigns may improve weight loss outcomes with minimal additional cost.
目的
我们研究了在社区减肥活动中增加行为减肥策略是否能改善减肥效果。
方法
Shape Up RI 是一项为期 12 周的在线团队健康改善计划，在罗德岛开展。在研究 1 中，我们随机将参与者分配到标准的 Shape Up RI 计划或该计划加关于减肥的视频课程。在研究 2 中，我们将参与者随机分配到标准计划或标准计划加视频课程、体重、饮食和运动的日常自我监测以及计算机生成的反馈。
结果
仅增加视频课程（研究 1）并没有显著改善减肥效果（2.0 ± 2.8 千克与 1.4 ± 2.9 千克；P =.15）。然而，当视频课程辅以自我监测和反馈（研究 2）时，平均减肥量增加了一倍以上（3.5 ± 3.8 千克与 1.4 ± 2.7 千克；P <.01），减肥 5%或更多的人的比例增加了两倍（40.5%与 13.2%；P <.01）。研究 2 中的参与者有 78%的天数提交了自我监测记录，并且坚持与结果显著相关。
结论
向社区减肥活动中增加行为策略可能会在不增加额外成本的情况下改善减肥效果。
