【摘要】 目的:基于身体质量指数(BMI)与体脂肪率(BF%)不同肥胖分类标准的差异,考察儿童体质健康指标分布的异同。方法:以上海市393名学龄儿童为研究对象,通过整群抽样法,对参与研究的学生进行身体形态、身体成分及身体素质测量,通过LMS法和线性回归等方法,考察体征指标的分布特征。结果:基于BMI和BF%的不同分类标准,对应的腰围、基础代谢率、立定跳远等指标均反映出了较大差异,男、女生腰围、立定跳远、基础代谢率之间存在显著性差异。结论:BMI与"金标准"BF%划分的儿童肥胖率不一致,对应的各项体征指标的分布存在较大差异性。更多还原

【Abstract】 Purpose: Based on the differences between BMI( Body Mass Index) and BF%( Body Percentage) in obesity classification criteria,the study examines the similarities and differences among body shape,body composition and physical fitness. Methods: the subjects are 393 elementary school students in Shanghai,whose body shape,body composition and physical fitness are measured. LMS and linear regression are used to investigate the distribution characteristics of physical sign indexes. Results: waist circumference,basal metabolic rate,standing long jump and other indicators showed great differences based on different obesity classification criteria by BMI and BF%. Conclusions: The recognition of obesity for children by classification criteria of BMI and the "gold standard"BF% is not exactly the same. The classification criteria of BMI and BF% have significant differences.更多还原
