如何減少代謝症候群所引發之健康風險是社區健康促進的一個重要議題。本研究為探討短期社區生活型態介入計畫對中年婦女代謝危險因子控制之成效。以立意取樣方式招募具有1個以上代謝危險因子或身體質量指數 24 ≧ ㎏/㎡之中年婦女受試者共57名，依照課程參與意願分為兩組，實驗組(37名)是接受18週生活型態介入計畫，內容包含10週團體課程(含營養教育、身體活動促進及支持團體模式導入)與8週居家自主健康管理，對照組(20名)則不接受任何的實驗處理。研究前後測量兩組之身體組成與血液生化值。對照組在前後測之各身體組成及血液生化值均無顯著差異，而實驗組在體重、腰圍、身體質量指數及體脂肪率等均有顯著降低(p<.05)；但在血液生化值則無顯著差異。當進一歩以兩組前測為共變項所進行之共變數分析後發現，實驗組後測之腰圍、體脂肪率及低密度膽固醇值顯著低於對照組後測值(p＜.001)。18週之社區生活型態介入計畫可改善中年婦女之腰圍，進而降低代謝症候群的危險因子。

How to reduce the health risks caused by metabolic syndrome is critical to the promotion of health in a community. This study investigated the effect of a short-term community-based lifestyle intervention program on metabolic risk factors in middle-aged women. Fifty-seven middle-aged women with at least one metabolic risk or their body mass index ≧ 24 ㎏/㎡ were recruited in this study by purposive sampling. They were divided into two groups according to the willing of participation in lifestyle intervention program. In the experimental group (EXP), 37 subjects took the 18-week lifestyle intervention program which included 10-week group lessons (contained nutrition education, physical activity promotion and the introduction of a supported-group model) and 8-week self-monitoring management. The other 20 subjects served in the control group (CON) and did not take any lesson. The analysis of body composition and serum biochemical parameters were conducted before and after the program. In CON, there were no significant differences on body composition and serum biochemical parameters before and after the program. In EXP, body weight, waist circumference (WC), body mass index and body fat percentage significantly decreased (p<.05) after the program, while there were no significant differences on serum biochemical parameters. After carrying out ANCOVA with the pre-test results of the two groups as the covariate, the post-test values of WC, body fat percentage and low-density lipoprotein in EXP were significantly lower than the post-test results for the same items in CON (p＜.001). The 18-week lifestyle intervention program may improve WC in middle-aged women and reduce the risk factors of metabolic syndrome.
