目的：代謝症候群是近年來威脅原住民健康的重要議題之一，而身體活動量的不足， 是否為導致代謝症候群發生的危險因子仍然未十分明確。本研究的目的在探討原住民社區 居民工作活動量和代謝症候群的關係。 方法：本研究為橫斷性、以北部某原住民社區成年居民為收錄對象，依勞動活動時間 分為每週28小時以上、每週超過零小時但低於28小時以及沒有勞動者共三組，進行代謝症 候群流行病學之相關分析與探討。 結果：174名山地鄉原住民中，代謝症候群盛行率為48.3%。而代謝症候群的各項指標 當中，以腰圍異常和血壓偏高的比例最高；去氫表雄固酮酯化物(DHEA-S)數值在各組間呈 現顯著差異(P<0.05)，以勞動每週28小時以上的組別為最低，然而代謝症候群盛行率在各勞 動分組間無統計上顯著差異。代謝症候群的相關危險因子中，尿酸為正的預測因子[曲線下 面積(AUC)=0.609, 95%CI=0.528~0.69,P=0.01]，而去氫表雄固酮酯化物為負的預測因子[曲線 下面積=0.685,95%CI=0.608~0.763,P<0.01]。 結論：較長時間勞動的工作族群並沒有較低代謝症候群盛行率，預防代謝症候群仍需 注重於飲食控制以及增加個人整體有氧運動之活動量。

Background and purpose：Metabolic syndrome has received massive attention for years because of its correlation with high risk of cardiovascular disease and diabetes. Previous studies have shown a high prevalence of metabolic syndrome in aboriginal community. Besides, sedentary activity is associated with metabolic syndrome. Therefore, the purposes of this study is to explore the relationship between manual labor and metabolic syndrome in aboriginal community. Methods：We used the database of the health examination of the residents in an aboriginal community in northern Taiwan in 2010. The enrolled residents were divided into three groups according to the hours they took to do the labor work in one week(no labor work; time of labor work: 0~< 28hours/week; time of labor work:≧ 28hours/week). The definition of MS in light of the criteria proposed by Taiwan Department of Health in 2007 was adopted in this study. Results：174 aboriginal residents were enrolled and the prevalence of Metabolic syndrome was 48.3%. Among the five conditions of metabolic syndrome, the abdominal obesity and elevated blood pressure were the most prevalent abnormalities. No significant difference existed in the prevalence of MS among three groups. There were significant difference in mean dehydroepiandrosterone sulfate (DHEA-S) level among three groups (P<0.05). The heavy manual labor group (time of labor work:≧ 28hrs/week) had the lowest mean DHEAS level. Logistic regression showed that uric acid was the positive predict factor for metabolic syndrome (AUC=0.609, 95%CI=0.528~0.691,P=0.01), and DHEA-S was the negative predict factor for metabolic syndrome (AUC=0.685,95%CI=0.608~0.763,P<0.01)。 Conclusion：Residents with more heavy manual labor did not have the less prevalence of metabolic syndrome. Therefore, in order to prevent metabolic syndrome, we still need to control the calories intake and to increase the amount of total daily physical activity.
