肥胖及代謝症候群，隨著全球之盛行，為廣受重視及亟待處理之公共衛生議題。本研究以1993-1996年及2005-2008年之臺灣營養健康調查（NAHSIT）的資料進行分析，探討臺灣代謝症候群及相關飲食型態之變遷趨勢。兩次調查之間，代謝症候群盛行率大幅增加，由13.6%上升至25.5%。NAHSIT2005-2008顯示，女性代謝症候群盛行率之年齡趨勢於45歲與男性之盛行率年齡趨勢交叉，而隨後高於男性。由地區差異來看，都市化程度及人口密度最高之北一地區，肥胖與代謝症候群盛行率之增加趨勢減緩；客家、中部及南部地區，肥胖與代謝症候群盛行率仍快速增加。原住民（山地）地區之肥胖與代謝症候群盛行率仍高居臺灣各地區及族群之首位。男性代謝症候群盛行率近十二年增加快速，而女性之盛行率增加趨勢較緩和。將臺灣之數據與國際間比較，臺灣之肥胖盛行率較亞洲許多國家高，但低於西方國家。但臺灣女性之代謝症候群盛行率相當接近西方國家。減維度迴歸分析顯示在女性中，降低代謝症候群罹患風險之飲食型態，其特徵除蔬菜、水果、瘦肉及魚類之高攝取頻率外，亦包含臺灣特性飲食項目之黃豆類、蕈菇類、海藻類等的高攝取。某些與代謝症候群相關之健康飲食項目，如瘦肉、奶類、深綠色蔬菜、及水果等，在十二年間之攝取頻率未見增加，值得後續健康促進及教育上來努力。

Obesity and the metabolic syndrome (MetS) are challenging public health issues as globesity popularizes. The present study illustrates the trend of obesity and MetS for the last 12 years in Taiwan based on the analysis of Nutrition and Health Survey in Taiwan. Between the two surveys, a large growth on MetS prevalence was observed, from 13.6% to 25.5%. In NAHSIT 2005-2008, the prevalence of MetS in females exceeded that of males in people older than the age of 45. With regard to regional differences, the growing prevalence of obesity and the metabolic syndromes alleviated in the northern area level one, the most urbanized and dense area. Prevalence of obesity and MetS in Hakka, central, and southern areas increased rapidly. Aboriginal areas had the highest prevalence, which increased modestly. Prevalence of MetS rose fast among males, but much slower among females. Comparing the Taiwanese data with other countries, obesity prevalence in Taiwan was higher than in many of Asian countries, but less than in the West. The prevalence of MetS in Taiwanese females reached levels close to that of the West. Reduced rank regression analysis was used to extract a risk reducing dietary pattern in women, featured by not only more vegetables, fruit, lean meat, and fish, but also some specific Taiwanese dietary items including mushrooms, seaweed, and soybean. No apparent increase in intake of certain healthy foods including lean meat, milk, dark-green vegetables, and fruit in the last 12 years, challenges future strategies to promote health.
