青少年的健康成长对于人口高质量发展具有承上启下的重要作用。依据较大规模的社会调查数据,运用链式中介分析法,探讨青少年体育活动与健康状况的关系,以及学业压力和睡眠质量的中介作用。结果显示:1)体育活动、健康状况、学业压力与睡眠质量两两之间均存在显著相关性;2)体育活动既能直接影响青少年的健康状况,也可以通过学业压力和睡眠质量的中介作用间接影响健康状况;3)学业压力和睡眠质量在体育活动和健康状况之间发挥链式中介效应。研究结果揭示了青少年学业压力和睡眠质量对青少年健康状况的作用机制,提示要更科学、准确地理解青少年德智体美劳全面、均衡发展的内涵。

The healthy development of adolescents serves playing a critical role in bridging the past with the future and ensuring the high-quality development of the population.Based on the data from a relatively large scale social survey,a chain mediation analysis was used to investigate the association relationship between adolescents’physical activity and health status,and the mediating effects of academic stress and sleep quality.The results shows that:1)Significant correlations existed among physical activity,health status,academic stress,and sleep quality;2)physical activity was found to directly affect adolescents’health status and indirectly affected it through the mediating effects of academic stress and sleep quality;3)academic stress and sleep quality exert a chain mediating effect between physical activity and health status.The research findings reveal the mechanism through which academic stress and sleep quality affect adolescents’health status,suggesting that we need a more scientific and accurate understanding of the connotation of the comprehensive and balanced development of adolescents in moral,intellectual,physical,and aesthetic education with a hard-working spirit and work skills.
