方法Shape Up RI是罗德岛州一个为期12周的在线健康改善计划。在研究1中，我们随机将参与者分配到标准Shape Up RI计划或该计划加上有关减肥的视频课程。在研究2中，我们随机将参与者分配到标准计划或计划加上视频课程，每天自我监测体重、锻炼和计算机生成的反馈。结果单独添加视频课程(研究1)没有显著改善体重减轻(2 0+/-2 8 kg vs 1 4+//-2 9公斤P=15)然而，当视频课程加上自我监控和反馈时(研究2)，平均体重减轻了一倍以上(3 5+/-3 8公斤对1 4+/-2 7公斤P<；研究2的参与者在78%的天数中提交了自我监测记录，并且坚持与结果显著相关。结论在社区活动中加入行为策略可能会以最小的额外成本改善减肥效果(Am J Public Health 2010 1002513-2519 DOI 102105/AJPH2009 183616)
Objectives We examined whether adding behavioral weight loss strategies could improve the outcomes of a community weight loss campaignMethods 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 feedbackResults 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 outcomeConclusions Adding behavioral strategies to community campaigns may improve weight loss outcomes with minimal additional cost (Am J Public Health 2010 100 2513-2519 doi 10 2105/AJPH 2009 183616)
