Correlation between Chinese adolescent mental sub-health and muscle strength index

Abstract

Objective To understand the mental sub-health status of Chinese adolescents and its correlation with muscle strength index, and to provide information for relevant research in mental health and muscle strength development of Chinese adolescents. Methods A total of 16 545 adolescents aged 13–22 year-old in six administrative regions of China were administered with the Adolescent Sub-Health Multidimensional Assessment Questionnaire (MSQA). Muscle strength indicatros were tested and its relations with mental sub-health were analyzed. Results The detection rates of Chinese adolescents’ emotional problems, character problems, social adjustment difficulties, and mental sub-health status were 25.5%, 25.0%, 16.0%, and 19.7%, respectively. The detection rates of mental sub-health status of adolescents in the group of muscle index P 75 were 30.3%, 19.0%, and 10.4%, respectively, and the difference was statistically significant (χ 2 =522.03, P P 75 群体青少年的心理亚健康状 态检出率分别为30.3%, 19.0%, 10.4%, 差异有统计学意义(χ 2 =522.03, P <0.01)。Logistic回归分析显示, 初中( OR = 2.55), 高中( OR = 2.27), 男生( OR =1.15), 肌肉指数为< P 25 ( OR =3.81), P 25 – P 75 ( OR = 2.03)青少年与心理亚健康状态均呈现正向 关联( P 值均<0.01)。 结论 中国青少年肌肉力量指数与心理亚健康之间存在相关关系, 肌肉力量指数越高则心理亚健康 检出率越低。
