目的了解畲族女大学生的肥胖情况并预测畲族女大学生的体脂百分比,为有效预防大学生肥胖提供科学依据。方法随机抽取丽水学院畲族女大学生159名,进行体成分和常用体质指标测试。结果以形态、机能、素质指标为自变量,以畲族女大学生体脂百分比指标为因变量,运用统计方法科学的研究方法,进行逐步回归分析。选出预测畲族女大学生体脂百分比的3个回归模型为y^=-7.291+1.665×BMI,y^=-5.960+2.846×BMI-0.794×体重/身高×100,y^=-13.338+2.714×BMI-0.758×体重/身高×100+0.040×800 m跑。结论可利用BMI等指标预测畲族女大学生体脂百分比。
Objective To understand the obesity status of She female college students and to predict the percentage of body fat of She female college students in order to provide a scientific basis for the effective prevention of obesity among college students. Methods A total of 159 She female female college students from Lishui University were randomly selected to test body composition and common physical fitness indexes. Results Morphology, function, quality indicators as independent variables, She female college students body fat percentage index as the dependent variable, the use of statistical methods of scientific research methods, step by step regression analysis. Three regression models for predicting body fat percentage of She female college students were y ^ = - 7.291 + 1.665 × BMI, y ^ = - 5.960 + 2.846 × BMI-0.794 × weight / height × 100, y ^ = - 13.338 + 2.714 × BMI-0.758 × weight / height × 100 + 0.040 × 800 m run. Conclusion BMI and other indicators can be used to predict female college students fat body percentage.
