While group interventions for weight management have been shown to be efficacious, adherence is often low, especially among men. This pilot study seeks to test whether group interventions using web-based group video conferencing (VC) technology is effective for weight loss. We adapted a 12-week curriculum based on the Diabetes Prevention Program, and delivered this intervention to a small group of men (BMI ≥30 kg/m(2)), using web-based group VC. Participants were randomized to intervention (n = 32) or delayed-intervention control group (n = 32). The intervention group lost 3.5 % (95 % CI 2.1 %, 4.9 %) of their initial body weight. Difference in mean weight loss was 3.2 kg (p = 0.0002) and mean BMI decrease was 1.0 kg/m(2) (p = 0.0010) between the two groups. Virtual small groups may be an effective means of allowing face-to-face group interaction, while overcoming some barriers to access.
虽然已证明群体干预对体重管理有效，但依从性往往较低，尤其是在男性中。这项试点研究旨在测试使用基于网络的群体视频会议（VC）技术进行群体干预对减肥是否有效。我们基于糖尿病预防计划改编了一个为期12周的课程，并使用基于网络的群体视频会议将此干预措施提供给一小群男性（体重指数≥30kg/m²）。参与者被随机分为干预组（n = 32）或延迟干预对照组（n = 32）。干预组初始体重减轻了3.5%（95%可信区间2.1%，4.9%）。两组之间平均体重减轻差异为3.2kg（p = 0.0002），平均体重指数下降为1.0kg/m²（p = 0.0010）。虚拟小组可能是一种有效的方式，既能实现面对面的群体互动，又能克服一些获取障碍。
