The Weight Loss Maintenance Trial tested strategies for maintenance of weight loss. Personal contact was superior to interactive technology and self-directed conditions.
We aimed to identify behavioral mediators of the superior effect of personal contact vs. interactive technology and of personal contact vs. self-directed arms.
Overweight/obese adults at risk for cardiovascular disease (n = 1,032) who lost at least 4 kg were randomized to personal contact, interactive technology, or self-directed. After 30 months, 880 participants had data on weight and behavioral strategies.
Reported increase of intake of fruits and vegetables and physical activity and more frequent self-weighing met criteria as mediators of the better outcome of personal contact vs. interactive technology. Increased intake of fruits and vegetables, more frequent self-weighing, and decreased dessert consumption were mediators of the difference between personal contact vs. self-directed.
Inducing changes in the identified behaviors might yield better outcomes in future weight loss maintenance trials.
减肥维持试验测试了维持体重减轻的策略。人际接触优于交互式技术和自我指导条件。
我们旨在确定人际接触与交互式技术相比以及人际接触与自我指导组相比产生优越效果的行为中介因素。
将至少减重4千克的有心血管疾病风险的超重/肥胖成年人（n = 1032）随机分为人际接触组、交互式技术组或自我指导组。30个月后，880名参与者有体重和行为策略的数据。
报告的水果和蔬菜摄入量增加、身体活动增加以及更频繁的自我称重符合作为人际接触与交互式技术相比取得更好结果的中介因素的标准。水果和蔬菜摄入量增加、更频繁的自我称重以及甜点摄入量减少是人际接触与自我指导组之间差异的中介因素。
在未来的减肥维持试验中，促使已确定行为发生改变可能会产生更好的结果。
