To test the efficacy of a weight loss intervention designed to appeal to men.
A randomized trial tested the efficacy of the Rethinking Eating and FITness (REFIT) weight loss program compared to a wait-list control. The 6-month intervention was delivered via two face-to-face sessions followed by Internet contacts. REFIT encouraged participants to create calorie deficits by making six 100-calorie changes to their eating daily while increasing physical activity, and the program encouraged customization through selection of specific diet strategies evaluated each week.
Participants (N = 107, 44.2 years, 31.4 kg/m(2) , 76.6% white) were randomized into the study, and 90.6% provided data at 6 months. REFIT participants lost -5.0 kg (95% CI: -6.1, -3.9) at 3 months, which was maintained through 6 months (-5.3 kg, 95% CI: -6.5, -4.2); this was greater than the control group (p < 0.001; 6 months: -0.6, 95% CI: -1.8, 0.5). More REFIT participants (49%) achieved a 5% weight loss than control participants (19%; OR 9.4; 95% CI: 3.2, 27.4). An average of 11.2 (±2.7) of 13 of the online intervention contacts were completed.
The novel REFIT intervention produced clinically significant weight losses. This approach holds promise as an alternative to traditional behavioral therapy for men.
测试一项旨在吸引男性的减肥干预措施的效果。
一项随机试验测试了“重新思考饮食与健身”（REFIT）减肥计划与等待名单对照组相比的效果。为期6个月的干预通过两次面对面课程，随后进行网络联系来实施。REFIT鼓励参与者通过每天对饮食做出六项100卡路里的改变来创造热量缺口，同时增加身体活动，并且该计划通过选择每周评估的特定饮食策略来鼓励个性化定制。
参与者（N = 107，44.2岁，31.4 kg/m²，76.6%为白人）被随机纳入研究，90.6%的参与者在6个月时提供了数据。REFIT参与者在3个月时体重减轻了5.0 kg（95%置信区间：-6.1，-3.9），并持续到6个月（-5.3 kg，95%置信区间：-6.5，-4.2）；这一减重幅度大于对照组（p < 0.001；6个月时：-0.6，95%置信区间：-1.8，0.5）。实现5%体重减轻的REFIT参与者比例（49%）高于对照组参与者（19%；比值比9.4；95%置信区间：3.2，27.4）。在线干预联系的13项中平均完成了11.2（±2.7）项。
新颖的REFIT干预措施产生了具有临床意义的体重减轻。这种方法有望成为男性传统行为疗法的替代方案。
