Human support can boost weight reduction in Internet-based weight-loss intervention. However, the most effective way to combine human support and the Internet for weight loss is unclear. This study aimed to examine the effects of two weight-loss programs for male workers aged 18-39 that combined different intensities of human support with website support compared to a delayed-intervention group (control group; CG), in a randomized controlled trial.
Seventy-one participants with overweight or obesity were allocated to one of three 12-week treatment programs. The Standard Support Group (SSG) was provided support via website and two face-to-face group guidance sessions, at the beginning and at the end of the program along with monthly general emails throughout the program. The Enhanced Support Group (ESG) received four remote support sessions based on Supportive Accountability (SA) in addition to the SSG. The CG was provided the same program as SSG after the other two groups had completed the program. The primary outcome was body weight reduction.
ESG participants reduced their weight significantly more than SSG and CG participants (P = 0.038, P < 0.001, respectively), and SSG participants reduced their weight significantly more than CG participants (P = 0.033).
The additional remote human support provided to the participants in the ESG was beneficial for weight loss in male workers. The low-intensity program provided to the SSG was also effective. Further studies with more participants in diverse settings and with participants who are less interested in their health and weight management are needed.
人为支持可以促进基于互联网的减肥干预中的体重减轻。然而，将人为支持与互联网结合用于减肥的最有效方法尚不清楚。本研究旨在检验两种减肥方案对 18-39 岁男性工人的影响，这些方案将不同强度的人为支持与网站支持相结合，与延迟干预组（对照组；CG）进行比较，采用随机对照试验。
71 名超重或肥胖的参与者被分配到三个为期 12 周的治疗方案之一。标准支持组（SSG）通过网站和两次面对面小组指导会议提供支持，在计划开始和结束时提供，并在整个计划期间每月提供一般性电子邮件。增强支持组（ESG）除了 SSG 之外，还根据支持性问责制（SA）提供了四个远程支持会议。CG 在其他两组完成计划后，获得与 SSG 相同的计划。主要结果是体重减轻。
ESG 参与者的体重减轻明显多于 SSG 和 CG 参与者（P=0.038，P<0.001），SSG 参与者的体重减轻明显多于 CG 参与者（P=0.033）。
为 ESG 参与者提供的额外远程人为支持有助于男性工人减轻体重。为 SSG 提供的低强度计划也有效。需要在更多不同环境和对健康和体重管理不太感兴趣的参与者中进行进一步研究。
