目标。这项试验比较了仅基于网络的干预(WO)和基于网络的辅以同伴主导的讨论(WD)或专业电子邮件咨询(WE)在3个阶段实现减肥和保持体重的有效性，这些女性来自服务不足的农村社区。方法：研究方法。30 1名妇女(体重指数为28~45 kg/m2)随机分为三组，分别接受指导减肥(基线为6个月)、指导减肥和维持体重(6至18个月)和自我管理体重维持(18至30个月)。结果。术后6个月、18个月和30个月的保留率分别为88.7%、76.5%和71.8%。意向治疗分析表明，在任何阶段，体重变化没有组间差异。6个月时，WO组、WD组和WE组观察到的平均体重下降(SD)分别为5.1(6.0)kg、4.1(5.6)kg和6.0(6.3)kg，分别为42%、38%和51%，符合≥的5%。这些比例在第二阶段之后下降了三分之一，在第三阶段没有进一步的变化。基于网络的干预措施帮助农村社区的妇女实现了6个月的减肥，30个月后体重恢复了一半。没有群体差异的潜在原因是基于网络的干预的强健性质。试行注册。这项试验已在ClinicalTrials.gov NCT01307644注册。
Objective. This trial compared the effectiveness of a web-based only (WO) intervention with web-based supplemented by peer-led discussion (WD) or professional email counseling (WE) across 3 phases to achieve weight loss and weight maintenance in women from underserved rural communities. Methods. 301 women (BMI of 28–45 kg/m2) randomly assigned to groups participated in guided weight loss (baseline to 6 months), guided weight loss and maintenance (6 to 18 months), and self-managed weight maintenance (18 to 30 months). Results. Retention was 88.7%, 76.5%, and 71.8% at 6, 18, and 30 months, respectively. Intent-to-treat analyses demonstrated no group differences in change in weight within any phases. At 6 months, observed mean (SD) weight loss was 5.1 (6.0) kg in WO, 4.1 (5.6) kg in WD, and 6.0 (6.3) kg in WE, with 42%, 38%, and 51%, respectively, meeting ≥ 5% weight loss. These proportions dropped by a third after phase 2 with no further change during phase 3. Conclusion. Web-based interventions assisted women from rural communities in achieving 6-month weight loss, with weight regain by half at 30 months. No group differences were potentially due to the robust nature of the web-based intervention. Trial Registration. This trial is registered with ClinicalTrials.gov NCT01307644.
