為了探討成年前不同族別間的身體質量指數(Body Mass Index: BMI)和高尿酸血症是否不同;本研究選取三族原住民(布農族、排灣族及泰雅族)及二族原住民(閩南及客家)之兒童(5-14歲)作為研究樣本,並將布農族、排灣族合稱為南部原住民,泰雅族稱為北部原住民。 本研究於民國83年3月到12月共從新竹縣尖石鄉、屏東縣高樹鄉要三地鄉及高高雄縣三民鄉收集1236位5至14歲的兒童,為研究對象。結果顯示,高尿酸血症(≥7.5 mg/dl)有28.5%(352/1236),且有9.5% (118/1236)其身體質量指數高於或等於22 kg/m2。在初步分析和以邏輯迴歸做校正後發現,有關導致高尿酸症的因子中,在本研究有年齡、性別、身體質量指數、族別Triglyceride(TG)和膽固醇濃度等。肥胖(BMI ≥ 22 kg/m2)在性別間並沒有差異(OR=1.0;95% CI=0.7-1.5),且北部原住民與非原住民也沒有差異(OR=1.0;95% CI=0.6-1.6);反而,在邏輯迴歸校正後,年紀大、高尿酸血症者、高TC濃度者以及南部原住民有較大的體重指標。本篇結論為原住民(包括南部和北部原住民)對向中尿酸濃度有重要的影響,但南部原住民比起非原住民及北部原住民有較大的身體質量指數。
To explore the relationship between the body mass index (BMI) and uric acid in different races before growing up into adulthood, we selected a total of 1236 five to 14 year-old children in the period from March to December 1994. The children originated from three Aboriginal tribes (the Bunun, and the Paiwan tribes – classified as South-Aborigines and Atayal tribe as North-Aborigines) and two non-Aboriginal tribes (Fukein-Taiwanese and Hakka), all of whom are from the following four contries: Chien-Shih, Sandimen, Gaushuh and Sanmin. The results showed that the percentage of hyperuricemia (≥ 7.5 mg/dl) was 28.5% (352/1236) and of obesity (BMI ≥ 22 kg/m2) was 9.5% (118/1236). Increased uric acid concentration was found to be related to age, sex, BMI, race, triglyceride (TG) and cholesterol levels in both the primary analysis and after the adjusted logistic regression model. Obesity did not vary with sex (OR=1.0;95% CI=0.7-1.5), or with Aborigines in north Taiwan as compared with non-Aborigines (OR=1.0;95% CI=0.6-1.6), but the logistic regression model adjusted for age indicated large BMI values for children with high serum uric acid concentration, triglyceride levels and the Aborigines who originated from south Taiwan. It was concluded form this study that both of the North-Aborigines and South-Aborigines made an important influence on serum uric acid concentration in children, especially the South-Aborigines made difference to BMI as compared with non-Aborigines and North-Aborigines.
