互联网接入的迅速增加使其成为一种可行的公共卫生干预模式。没有对照研究评价了这种资源的weightloss.Objective目的是为了确定是否结构化的互联网行为减肥计划产生更大的初始体重减轻和腰围的变化比减肥教育Website.Design随机对照试验进行了从1999年4月至12月。年龄在18至60岁之间，体重指数为25至36 kg/m（2）的超重成人医院员工。干预参与者被随机分配到一个为期6个月的减肥计划，无论是互联网教育（教育; n=32与完整的数据）或互联网行为疗法（行为疗法; n=33与完整的数据）。所有参与者都有一个面对面的小组减肥会议，并访问一个网站，有组织的链接到互联网减肥资源。行为治疗组的参与者接受了额外的行为程序，包括通过电子邮件每周24次的行为课程，通过电子邮件每周在线提交的自我监控日记与个性化的治疗师反馈，和一个在线bulletinboard.Main结果测量体重和腰围，在0，3和6个月测量，比较了2个干预组。结果重复测量分析显示，行为治疗组比教育组减轻了更多的体重（P= 0.005）。行为治疗组3个月时平均（SD）减轻4.0（2.8）kg，6个月时平均减轻4.1（4.5）kg。教育组在3个月时体重减轻1.7（2.7）kg，6个月时体重减轻1.6（3.3）kg。6个月时，行为治疗组比教育组更多的参与者达到了5%的减肥目标（45% vs 22%; P=.05）。腰围的变化也更大的行为治疗组比教育组在3个月（P= 0.001）和6个月（P = 0.005）。结论参与者谁得到了一个结构化的行为治疗计划，每周接触和个性化的反馈有更好的减肥相比，那些提供教育网站的链接。因此，互联网和电子邮件似乎是可行的方法，提供结构化的行为减肥计划。
Context Rapid increases in access to the Internet have made it a viable mode for public health intervention. No controlled studies have evaluated this resource for weight loss.Objective To determine whether a structured Internet behavioral weight loss program produces greater initial weight loss and changes in waist circumference than a weight loss education Web site.Design Randomized controlled trial conducted from April to December 1999.Setting and Participants Ninety-one healthy, overweight adult hospital employees aged 18 to 60 years with a body mass index of 25 to 36 kg/m(2). Analyses were performed for the 65 who had complete follow-up data.Interventions Participants were randomly assigned to a 6-month weight loss program of either Internet education (education; n=32 with complete data) or Internet behavior therapy (behavior therapy; n=33 with complete data). All participants were given 1 face-to-face group weight loss session and access to a Web site with organized links to Internet weight loss resources. Participants in the behavior therapy group received additional behavioral procedures, including a sequence of 24 weekly behavioral lessons via e-mail, weekly online submission of self-monitoring diaries with individualized therapist feedback via e-mail, and an online bulletin board.Main Outcome Measures Body weight and waist circumference, measured at 0, 3, and 6 months, compared the 2 intervention groups. Results Repeated-measures analyses showed that the behavior therapy group lost more weight than the education group (P=.005). The behavior therapy group lost a mean (SD) of 4.0 (2.8) kg by 3 months and 4.1 (4.5) kg by 6 months. Weight loss in the education group was 1.7 (2.7) kg at 3 months and 1.6 (3.3) kg by 6 months. More participants in the behavior therapy than education group achieved the 5% weight loss goal (45% vs 22%; P=.05) by 6 months. Changes in waist circumference were also greater in the behavior therapy group than in the education group at both 3 months (P=.001) and 6 months (P =.005).Conclusions Participants who were given a structured behavioral treatment program with weekly contact and individualized feedback had better weight loss compared with those given links to educational Web sites. Thus, the Internet and e-mail appear to be viable methods for delivery of structured behavioral weight loss programs.
