北京海淀区中小学生BMI与素质指标相关性分析

目的探讨北京海淀区中小学生BMI与体质指标之间关系,为客观评价学生体质健康状况提供科学依据。方法采用分层随机整群抽样,抽取海淀区7～18岁中小学生1 100名为研究对象,应用方差分析、相关及偏相关对各项人体测量指标进行统计分析。结果各身体素质指标水平在不同BMI等级中差异有统计学意义,在控制年龄、性别的影响后,BMI与握力(r=0.30)、50 m跑(r=0.17)、50m×8往返跑(r=0.45)、男生1 000 m(r=0.49)、女生800 m跑(r=0.29)呈显著正相关;BMI与斜身引体(r=-0.26)、引体向上(r=-0.28)、立定跳远(r=-0.23)、仰卧起坐(r=-0.13)呈显著负相关。结论随着超重、肥胖学生比例的增加,对身体素质评价的影响也在增大;需要建立更为客观的学生体质健康综合评价体系。
