    關(guān)鍵信息

    在本研究中，作者在農(nóng)村社區(qū)隨機(jī)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（僅營養(yǎng)指導(dǎo)無行為性治療）的對(duì)照組相比，接受中、高程度的治療組體重減少更顯著。中度和高度行為性減肥組之間并無顯著差異。性價(jià)比分析顯示中度干預(yù)治療更加適宜。

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