很少有关于两年以上成功长期减肥的调查，也没有调查过医疗服务不足的农村老年人口的体重变化。本研究的目的是评估居住在农村社区的 50-75 岁女性在完成为期六个月的肥胖生活方式干预后 3.5 年后的长期减肥维持情况。 110 名平均（±标准差）年龄为 60.08 ± 6.17 岁、平均体重指数为 36.76 ± 5.10 kg/m2 的肥胖女性完成了一次现场评估，评估了她们的体重和对行为体重管理策略的遵守情况。在最初的六个月干预期间，参与者的平均体重减轻了 10.17% ± 5.0%，从治疗完成到 3.5 年后的随访评估，体重恢复了 6.95% ± 9.44%。相当大比例的参与者 (41.80%) 能够从基线到随访期间保持体重减轻 5% 或更多。 “成功”的参与者（那些在随访中体重下降了 5% 或更多的人）报告称，与“不成功”的参与者（那些体重下降低于 5% 的人）相比，他们会称重自己的体重，自我监控自己的摄入量和卡路里，提前计划膳食，并更频繁地选择低热量食物。总的来说，这些研究结果表明，很大一部分参与者能够在治疗后多年保持临床上显着的体重减轻，并且自我监测是成功的长期体重管理的关键组成部分。
Few investigations of successful long-term weight loss beyond two years have been conducted, and none has examined weight changes in medically underserved rural populations of older adults. The purpose of this study was to assess long-term weight loss maintenance 3.5 years after the completion of an initial six-month lifestyle intervention for obesity among women aged 50–75 years residing in rural communities. One hundred and ten obese women with a mean (± standard deviation) age of 60.08 ± 6.17 years and mean body mass index of 36.76 ± 5.10 kg/m2 completed an in-person assessment during which their weight and adherence to behavioral weight management strategies were evaluated. Participants showed a mean weight reduction of 10.17% ± 5.0% during the initial six- month intervention and regained 6.95% ± 9.44% from the completion of treatment to follow-up assessment 3.5 years later. A substantial proportion of participants (41.80%) were able to maintain weight reductions of 5% or greater from baseline to follow-up. “Successful” participants (those who maintained losses of 5% or greater at follow-up) reported weighing themselves, self-monitoring their intake and calories, planning meals in advance, and choosing lower calorie foods with greater frequency than “unsuccessful” participants (those who lost less than 5%). Collectively, these findings indicate that a large proportion of participants were able to maintain clinically significant weight losses for multiple years after treatment, and that self-monitoring was a key component of successful long-term weight management.
