全国学生体质与健康的拓扑再分析

A topological reanalysis of the physical quality and health of students in China

引入自相似和定量差异对2010和2014两年的全国7~19岁学生体质与健康调研数据进行再分析。结果发现:(1)2014年与2010年比较,我国同龄小学生体质健康水平,女生上升,男生下降;同龄中学生的体质健康水平,女生下降,男生上升;同龄大学生的体质健康水平,男女生均相当。(2)2014年与2010年比较,我国女生在7~10、13和15岁时的体质健康水平明显提高,男生在7~11、13~15岁时的体质健康水平也明显提高。研究结果不支持学生体质健康状况下降的传统结论。
