我国少数民族青年学生体质水平综合评价的因子分析

Factor analysis of comprehensive evaluation of physique level of young Chinese minority students

利用1985年和2005年少数民族学生体质健康调研所获得的数据,运用因子分析法,对23个(女22个)少数民族18岁青年学生体质水平分别进行1985、2005年和20年变化的因子分析和综合评价。结果发现,①20年来,少数民族青年学生体质水平总体评价提高幅度较大的原因主要是身体素质发展水平和身体形态发育水平的提高,而提高幅度较差的主要原因是机能发育水平和素质发展水平多数出现明显下降所致;②1985年和2005年少数民族青年学生体质水平总体评价的5个等级各具特征,其体质水平的总体改善,要根据民族、性别、地域环境的差异而采取相应的措施。

Adopting data obtained from investigation of physique and health state of young Chinese minority students from 1985 to 2005 and applying factor analysis, results were found that young students whose physique level improved were those of the minority people who were better in fitness and body shape development. Young students whose physique level did not improve much were those of the minority people whose body function and physical development decreased. In order to improve the physique level of these students, measures should be taken according to differences in gender, nationality and region.
