原住民大學生身體組成現況調查研究－以國立勤益科大為例

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。
