本研究是以一代表性樣本,臺灣學童營養及健康調查來評估學童肥胖及其合併症盛行率,本調查是一分層多步驟抽樣調查。總計有2405名學童(男童1290名,女童1115名)參加本研究。男童過重及肥胖盛行率分別約為15.5%及14.7%;女童過重及肥胖盛行率分別為14.4%及9.1%。不同區域,男童肥胖盛行率最高地區為南部第三層(約23.3%),最低為山部地區(約4.3%)。女童肥胖盛行率最高為中部第三層區(約13.0%),最低為南部第三層抽樣地區(約2.6%)。肥胖學童的血壓、血三酸甘油酯、低密度脂蛋白膽固醇、尿酸及丙胺酸轉胺酶值等皆較正常體重學童為高,而高密度脂蛋白膽固醇值則較正常體重學童為低。肥胖及正常體重男童,其高血壓盛行率分別為12.9%比0.3%;血脂異常盛行率為31.4%比19.6%;肝功能指數異常盛行率為6.4%比0.8%。本研究發現,在臺灣約有三分之一男童及四分之一女童為體重過重或肥胖。更值得注意的是,肥胖或過重學童其肥胖相關合併症的盛行率也顯著的升高。
To evaluate the prevalence of obesity and its comorbidities among a representative sample of elementary schoolchildren in Taiwan, the Nutrition and Health Survey in Taiwan Elementary School Children used a stratified, multi-staged complex sampling scheme. In total 2,405 children (1,290 boys and 1,115 girls) were included. The prevalence of overweight and obesity was 15.5 and 14.7% in boys and 14.4 and 9.1% in girls. With respect to geographic differences, the prevalence of obesity for boys was highest in the southern area (23.3% for the 3^rd stratum) and lowest in the mountain area (4.3%). For girls, the prevalence of overweight and obesity was highest in the central area (13.0% for the 3rd stratum) and lowest in the southern area (2.6% for the 3^rd stratum). The obese children had higher mean levels of blood pressure, triglyceride, low density lipoprotein-cholesterol, uric acid and serum glutamic pyruvic transaminase, but lower level of high density lipoprotein-cholesterol when compared with the normal weight children. For obese and normal weight boys, the prevalence was 12.9 % vs. 0.3 % for high blood pressure, 31.4 % vs. 19.6 % for dyslipidemia, and 6.4 % vs. 0.8 % for abnormal serum glutamic pyruvic transaminase level. In conclusion, we found that about one third of the boys and one quarter of the girls were overweight and/or obesity in Taiwan. Furthermore, the prevalence of obesity-related comorbidities was significantly increased for obese and/or overweight elementary schoolchildren in the Taiwan area.
