Preliminary findings suggest that web-based interventions may be effective in achieving significant weight loss and weight loss maintenance. To date only few findings within primary care patients and especially the involvement of general practitioners are available. The aim of this trial was to examine the short-term effectiveness of a web-based coaching program in combination with an accompanied telephone counselling regarding weight reduction in a primary care setting.
The study was a cluster-randomized trial with an observation period of 12 weeks. Individuals recruited by general practitioners randomized to the intervention group participated in a web-based coaching program based on education, motivation, exercise guidance, daily SMS reminding, weekly feedback through internet and active monitoring by general practitioners. Participants in the control group received usual care and advice from their practitioner without the web-based coaching program. The main outcome was weight change between admission and after 12 weeks.
186 participants (109 intervention group, 77 control group) were recruited into study. For 76 participants from the intervention group and 72 participants from the control group weight measurements were available both at baseline and 12 weeks. Weight decreased on average by 4.2 kg in the intervention group and 1.7 kg in the control group (mean group difference 2.5 kg; 95%CI 1,1; 3,8; p < 0.001). Reductions for waist circumference and BMI were also significantly larger within intervention.
Findings of the present trial suggest that the tested web-based coaching program for weight loss is effective in short-term. Further RCTs are desirable in order to confirm present findings in larger populations and to investigate long-term outcomes.

初步研究结果表明，基于网络的干预措施可能在实现显著的体重减轻和体重维持方面有效。迄今为止，仅在初级保健患者中获得了一些发现，特别是全科医生的参与情况。本试验旨在检验一种基于网络的辅导计划与伴随的电话咨询相结合在初级保健环境中减少体重的短期效果。
该研究是一项基于群组的随机试验，观察期为 12 周。通过全科医生招募的个体随机分配到干预组，参加基于教育、动机、运动指导、每日短信提醒、通过互联网每周反馈以及全科医生的积极监测的基于网络的辅导计划。对照组的参与者接受来自其医生的常规护理和建议，但不参加基于网络的辅导计划。主要结局是入院和 12 周后的体重变化。
共招募了 186 名参与者（109 名干预组，77 名对照组）。干预组的 76 名参与者和对照组的 72 名参与者都有基线和 12 周时的体重测量值。干预组平均体重减轻了 4.2 公斤，对照组平均体重减轻了 1.7 公斤（平均组间差异 2.5 公斤；95%CI 1.1；3.8；p<0.001）。干预组的腰围和 BMI 减少也明显更大。
本试验的结果表明，测试的基于网络的减肥辅导计划在短期内是有效的。需要进一步的 RCT 来确认更大人群中的现有发现，并研究长期结果。
