背景由于许多成功的节食者重新获得了他们减掉的体重，因此需要教授维护技能的项目。我们开发了一个基于自我调节理论的维护计划，并测试了面对面或通过互联网提供该计划的有效性。方法我们将314名在过去两年中体重平均下降19.3公斤的参与者随机分配到三组中的一组：对照组，每季度收到时事通讯(105名参与者)，一组接受面对面干预(105人)，一组接受基于互联网的干预(104)。两个干预组的项目内容相同，强调日常自我称重和自我调节，与两组的接触频率也是如此。结果面对面组平均体重增长(+/-SD)为2.5+/-6.7 kg，互联网组为4.7+/-8.6 kg，对照组为4.9+/-6.5 kg，面对面组与对照组比较差异有统计学意义(2.4 kg；95%可信区间[CI]，0.002~10.8；P=0.0 5)。在18个月内体重恢复2.3公斤或以上的参与者比例，对照组(72.4%)显著高于面对面组(45.7%；绝对差异，27%；95%可信区间，14~39；P
BACKGROUNDSince many successful dieters regain the weight they lose, programs that teach maintenance skills are needed. We developed a maintenance program based on self-regulation theory and tested the efficacy of delivering the program face to face or over the Internet.METHODSWe randomly assigned 314 participants who had lost a mean of 19.3 kg of body weight in the previous 2 years to one of three groups: a control group, which received quarterly newsletters (105 participants), a group that received face-to-face intervention (105), and a group that received Internet-based intervention (104). The content of the programs in the two intervention groups was the same, emphasizing daily self-weighing and self-regulation, as was the frequency of contact with the groups. The primary outcome was weight gain over a period of 18 months.RESULTSThe mean (+/-SD) weight gain was 2.5+/-6.7 kg in the face-to-face group, 4.7+/-8.6 kg in the Internet group, and 4.9+/-6.5 kg in the control group, with a significant difference between the face-to-face group and the control group (2.4 kg; 95% confidence interval [CI], 0.002 to 10.8; P=0.05). The proportion of participants who regained 2.3 kg or more over the 18-month period was significantly higher in the control group (72.4%) than in the face-to-face group (45.7%; absolute difference, 27%; 95% CI, 14 to 39; P
