目的：探討原住民族大學生身體質量指數、體脂肪比、腰臀圍比等身體組成現況，調查結果與美國運動醫學會（ACSM）常模等級標準進行歸類分析。方法：以國立勤益科技大學69位具有原住民族籍身分的男、女學生為研究對象，年齡為18－22歲之間，測量其身高、體重、腰圍、臀圍求取身體質量指數與腰臀圍比，並利用身體組成分析儀（Biospace, Inbody 3.0）測量體脂肪比，測驗所得資料以SPSS for windows 18.0電腦套裝統計軟體處理，所有結果以平均值±標準差表示。結果：一、勤益科大原住民身分大學生之BMI指數平均值為25.0（男生為24.67、女生為25.26）；體脂肪百分比平均值為28.64%（男生為21.46%、女生為34.17%）；腰臀圍平均值為0.83（男生0.86、女生0.82）。二、以BMI指數衡量，體型過重與肥胖等級者，男生達40%，女生更高達43.6%。三、以體脂肪百分比評估體型過重與肥胖等級者，男生60%，女生更高達69.3%；四、以腰臀圍比男生全部在標準值以下，女生則有38.5%超出理想值。結論：勤益科技大學原住民身分大學生肥胖率偏高，女生又高於男生，應積極設法改善。

This study was designed to understand the body mass index, body fat, waist-hip ratio and body composition of aboriginal university students. The results were referred to the norm of American College of Sports Medicine (ACSM). Sixty-nine aboriginal students of both sexes aged 18–22 participated in this study. Data of body composition test parameters were collected, including height, weight, body fat circumference and the percentage of body fat was analyzed by physical composition analyzer Inbody 3.0 from Biospace. Data was processed by SPSS for windows 18.0 system and analyzed using the descriptive statistics. The results were as followed: (1) The average value of body mass index are 25.0 (24.67 in male, 25.26 in female, respectively); the average percentage of body fat are 28.64% (21.46% in male, 34.17% in female, respectively); the average value of waist-hip ratio are 0.83 (0.86 in male, 0.82 in female, respectively). (2) For body mass index, the percentage of being overweight and obesity are 40.0% in males, 43.6% in females, respectively. (3) For body fat, the percentage of being overweight and obesity are 60.0% in males, 69.3% in females, respectively. (4) For waist-hip ratio, all males under the standard, and 38.5% females over the standard.
