中国汉族中学生20m往返跑与心理亚健康的相关性

了解中国汉族青少年20 m往返跑(20 m SRT)与心理亚健康的相关性,为促进心理亚健康青少年的体质健康提供科学依据.方法 在华东、华北、中南、西北、西南和东北地区采用随机个案法随机抽取8 595名汉族青少年(13~18岁),采用20 m SRT和青少年亚健康多维评定问卷(Multidimensional Sub-health Questionnaire of Adolescents,MSQA)中的心理部分进行心肺耐力和心理亚健康测试.结果 中国汉族青少年心理亚健康状态总检出率分别为20.9%和21.3%.13~18岁男性青少年心理亚健康状态检出率为13.2% ~24.7%,其中18岁最低(13.2%),14岁最高(24.7%);女性青少年检出率介于15.4%~25.9%,其中18岁最低(15.4%),13岁最高(25.9%).高等级20 m SRT成绩男性青少年心理亚健康状态总体检出率为18.1%,低等级检出率为23.1%,差异有统计学意义(x2=15.713,P<0.05);女性青少年分别为19.5%和22.6%,差异有统计学意义(x2=6.035,P<0.05).多因素Logistic回归分析显示,地区(西南、西北和中南)、年龄(青春期后期)和20 m SRT(高等级)是儿童青少年心理亚健康状态检出率较低的主要影响因素(P值均<0.05).结论 青春期前期及心肺耐力水平较差的青少年心理亚健康状态检出率较高.

Association between 20 m shuttle run test and psychological sub-health among Chinese Han adolescents

Objective To detemine the relationship between 20-meter shuttle run(20 m SRT) and psychological sub-health status among Chinese Han adolescents.Methods Random sampling method was adopted to select adolescents from six major administrative regions in China.A total of 8 595 adolescents were investigated with Multidimensional Sub-health Questionnaire of Adolescents(MSQA) and 20 m SRT.Results The total prevalence of psychological sub-health symptoms of boys and girls in China was 20.9% and 21.3%,respectively.The prevalence rate of psychological sub-health symptoms among boy aged 13-18 years was between 13.2% and 24.7%,lowest among 18-year-olds(13.2%) and highest among 14-year-olds(24.7%);for girls,the figures were 15.4% and 25.9%,lowest among 18-year-olds(15.4%) and highest among 13-year-olds(25.9%).The total prevalence of psychological sub-health symptoms among boys with better 20 m SRT performance was 18.1%,significantly lower than that of boys with low 20 m SRT performance(23.1%) (P<0.05);for girls,the same pattern was found(19.5% and 22.6%,P<0.05).Logistic regression analysis showed that the prevalence rates of psychological sub-health symptoms in adolescents were lower in specific areas (southwest,northwest and South),age group(late adolescence) and students with better 20 m SRT performance(P<0.05).Conclusion Psychological sub-health symptoms is more prevalent in early adolescence and among adolescents with poor cardiorespiratory fitness.
