Correlation between physical fitness index and mental sub-health among Chinese adolescents

Abstract

Objective To investigate the association between mental sub-health and physical fitness of Chinese adolescents, to provide a reference for promoting the physical and mental health of Chinese adolescents. Methods A total of 16 545 adolescents (13–22 years) were selected by random cluster sampling in six major administrative regions in China. The psychological part of the Multidimensional Sub-health Questionnaire of Adolescents (MSQA) and the physical fitness index test were used to assess mental sub-health and physical fitness, respectively. The chi-square test and Logistic regression analysis were used to analyze and compare the relationships between different levels of physical fitness and mental sub-health. Results The overall detection rate of mental sub-health status among high-grade physical fitness index adolescents was 11.9%, and the detection rate among low-grade physical fitness index youths was 26.0%, and the difference was statistically significant ( χ 2 = 970.73, P <0.05). The overall detection rate among high-grade physical fitness index boys was 11.1%, and that of low-grade physical fitness index boys was 24.4%. The difference was statistically significant ( χ 2 = 566.12, P <0.05). The overall detection rate of mental sub-health status among high-level physical fitness index girls was 12.8%, and that among low-level physical fitness index girls was 27.6%, and the difference was statistically significant ( χ 2 =412.25, P <0.05). After adjusting for gender, age, BMI, and region in the Logistic regression model, the detection rate of mental sub-health status of adolescents with low-grade physical fitness index was 2. 35 times higher than that of high-grade physical fitness index adolescents (95% CI = 2.12–2.61). Conclusion Adolescents with poor physical fitness have a higher risk of mental sub-health. Attention should be paid to adolescent physical fitness development to comprehensively improve physical and mental health development. 【摘要】 目的 了解中国青少年心理亚健康和体能状况及其相关性, 为促进中国青少年身心健康发展提供参考。 方法 在中国华东、华北、中南、西北、西南和东北地区, 采用分层随机整体抽样法抽取 16 545 名 13~22 岁青少年, 采用青少年亚 健康多维评定问卷 (Multidimensional Sub-health Questionnaire of Adolescents, MSQA) 中的心理问卷进行心理亚健康调查, 同 时进行体能测试。采用 χ 2 检验及 Logistic 回归分析对青少年不同体能状况与心理亚健康的关系进行分析。 结果 高等级 体能指数青少年的心理亚健康状态总体检出率为 11.9%, 低等级检出率为 26.0%, 差异有统计学意义 (χ 2 = 970.73, P < 0.05)。高等级体能指数男生心理亚健康检出率为 11.1%, 低等级检出率为 24.4%, 差异有统计学意义 (χ 2 = 566.12, P < 0.05);高等级体能指数女生心理亚健康检出率为 12.8%, 低等级检出率为 27.6%, 差异有统计学意义 (χ 2 =412.25, P < 0.05)。Logistic回归模型在调整了性别、年龄、体质量指数和地区之后, 低等级体能指数青少年心理亚健康状态检出率为 高等级者的 2.35 倍 (95% CI =2.12〜2.61)。 结论 青少年体能水平较差者发生心理亚健康风险较高。应重视青少年体能 发展水平, 全面提升中国青少年身心健康发展。
