| 摘 要： | 引入韦伯-费希纳定律、时间自相似和Sigma算法对2010和2014两年全国7~18岁学生超重、肥胖检出率的调研数据进行再分析。结果发现:(1)从2010到2014年,我国7~18岁学生超重、肥胖检出率在性别上无拓扑差异,即中小学男女生的超重、肥胖检出率均呈自限性过程;(2)从2010到2014年,我国7~18岁学生超重、肥胖检出率在城乡上有拓扑差异,主要表现为乡村好于城市;(3)从2010到2014年,我国7~18岁学生超重、肥胖检出率在时间上产生了拓扑相变,主要表现为城市男生的超重检出率和城市女生的超重、肥胖检出率均呈上升趋势,而城市男生和乡村男女生的肥胖检出率均维持不变。结果表明当前我国城乡中小学生群体中只有城市女生肥胖检出率呈持续上升趋势。

| Abstract: | By introducing the Weber-Fechner law,time self-similarity and sigma algorithm,the authors reanalyzed the survey data of the overweight and obesity detection rates among students aged 7-18 in China in 2010 and 2014,and revealed the following findings:1)from 2010 to 2014,the overweight and obesity detection rates among students aged 7-18 in China had no topological difference in terms of gender,i.e.the overweight and obesity detection rates among elementary and middle school students presented a self-limiting process;2)from 2010 to 2014,the overweight and obesity detection rates among students aged 7-18 in China had topological differences in terms of city and countryside,mainly showing that countryside’s were better than city’s;3)from 2010 to 2014,the overweight and obesity detection rates among students aged 7-18 in China produced topological changes in terms of time,mainly showing that the overweight detection rate of urban male students and the overweigh and obesity detection rates of urban female students presented an increasing trend,while the obesity detection rates of urban male students and rural male and female students maintained unchanged.The findings indicated that among the groups of urban and rural elementary and middle school students in China nowadays,only the obesity detection rate of urban female students presented a constantly increasing trend. |
