    在本研究中，作者在農村社區隨機選擇了612名成年肥胖癥患者，并分析了行為性減肥治療的有效性和成本。與接受低度治療（僅營(yíng)養指導無(wú)行為性治療）的對照組相比，接受中、高程度的治療組體重減少更顯著(zhù)。中度和高度行為性減肥組之間并無(wú)顯著(zhù)差異。性?xún)r(jià)比分析顯示中度干預治療更加適宜。

    中等程度的行為治療對肥胖成人的體重的降低效果與高度的行為治療相當；然而，中等程度的治療性?xún)r(jià)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.
