关键信息

在本研究中，作者在农村社区随机选择了612名成年肥胖症患者，并分析了行为性减肥治疗的有效性和成本。与接受低度治疗（仅营养指导无行为性治疗）的对照组相比，接受中、高程度的治疗组体重减少更显著。中度和高度行为性减肥组之间并无显著差异。性价比分析显示中度干预治疗更加适宜。

中等程度的行为治疗对肥胖成人的体重的降低效果与高度的行为治疗相当；然而，中等程度的治疗性价比更高。

The authors of this randomized study evaluated the effects and costs of behavioral weight-loss treatment in 612 obese **s in rural communities. Significantly larger reductions in body weight were seen in the groups who received moderate and high degrees of therapy compared with the group who received a low degree and compared with the control group （who received nutrition education without behavioral instructions）。 No significant difference was seen between the group who received a moderate and the group who received a high degree of behavior therapy. The cost-effectiveness **yses favored moderate intervention over the other treatments.

A moderate degree of behavioral treatment was associated with weight reductions comparable with those apparent with a high degree in **s with obesity; however, the moderate treatment was more cost-effective.
