互联网上的减肥计划似乎对短期减肥很有希望，但尚未对2型糖尿病风险个体的减肥进行研究；因此，长期疗效尚不清楚。目的比较对有2型糖尿病风险的个体提供1年的单独网络减肥计划与通过电子邮件添加行为咨询的效果。2001年9月至2002年9月在罗德岛普罗维登斯进行的一项单中心随机对照试验，研究对象为92名超重成人，平均（SD）年龄为48.5（9.4）岁，体重指数为33.1（3.8）。干预措施参与者被随机分配到基本互联网（n=46）或互联网+行为电子咨询项目（n=46）。两组都接受了一次面对面的咨询和相同的核心网络项目，并被要求每周提交体重。电子咨询的参与者提交卡路里和运动信息，并每周收到来自咨询师的电子邮件行为咨询和反馈。主要观察指标在0个月和12个月测量体重和腰围。结果意向治疗分析显示，行为电子咨询组在12个月时的平均体重（SD）下降幅度大于基础互联网组（-4.4 [6.2]vs -2.0 [5.7] kg， P= 0.04），初始体重百分比（4.8% vs 2.2%， P= 0.03）、体重指数（-1.6 [2.2]vs -0.8 [2.1]， P= 0.03）和腰围（-7.2 [7.5]vs -4.4 [5.7] cm， P= 0.05）的下降幅度更大。结论：在基本的网络减肥干预项目中加入电子邮件咨询可以显著改善糖尿病高危成人的减肥效果。
Context Weight loss programs on the Internet appear promising for short-term weight loss but have not been studied for weight loss in individuals at risk of type 2 diabetes; thus, the longer-term efficacy is unknown.Objective To compare the effects of an Internet weight loss program alone vs with the addition of behavioral counseling via e-mail provided for 1 year to individuals at risk of type 2 diabetes.Design, Setting, and Participants A single-center randomized controlled trial conducted from September 2001 to September 2002 in Providence, RI, of 92 overweight adults whose mean (SD) age was 48.5 (9.4) years and body mass index, 33.1 (3.8).Interventions Participants were randomized to a basic Internet (n=46) or to an Internet plus behavioral e-counseling program (n=46). Both groups received 1 face-to-face counseling session and the same core Internet programs and were instructed to submit weekly weights. Participants in e-counseling submitted calorie and exercise information and received weekly e-mail behavioral counseling and feedback from a counselor.Main Outcome Measures Measured weight and waist circumference at 0 and 12 months.Results Intent-to-treat analyses showed the behavioral e-counseling group lost more mean (SD) weight at 12 months than the basic Internet group (-4.4 [6.2] vs -2.0 [5.7] kg; P=.04), and had greater decreases in percentage of initial body weight (4.8% vs 2.2%; P=.03), body mass index (-1.6 [2.2] vs -0.8 [2.1]; P=.03), and waist circumference (-7.2 [7.5] vs -4.4 [5.7] cm; P=.05).Conclusion Adding e-mail counseling to a basic Internet weight loss intervention program significantly improved weight loss in adults at risk of diabetes.
