During the period of COVID-19 pandemic, the social restrictions and isolation exerted a significant impact on the sleep quality of Chinese college students. This study aims to delve into the influence of physical activity on the sleep quality of college students as well as the mediating roles of stress and smartphone addiction.
A cohort of 274 eligible college students (146 males and 128 females) were selected for the investigation. The International Physical Activity Questionnaire Short Form, Stress Perception Scale, Smartphone Addiction Scale, and Pittsburgh Sleep Quality Index were employed to assess the levels of physical activity, stress, smartphone addiction, and sleep quality among college students. For data analysis, descriptive statistics, correlation analysis, and chained mediation effect tests were performed sequentially.
The findings revealed: (1) a significant negative correlation between physical activity and stress, smartphone addiction, and sleep quality among college students ( = -0.216, < 0.001; = -0.224, < 0.001; = -0.259, < 0.001); (2) independent mediating roles of stress and smartphone addiction in the relationship between physical activity and sleep quality; and (3) chained mediating effects of stress and smartphone addiction in the association between physical activity and sleep quality.
This study deepens our comprehension of how physical activity augments the quality of slumber, concurrently emphasizing that mitigating stress levels and alleviating smartphone addiction constitute effective strategies for preventing sleep issues among college students.
在新冠疫情期间，社交限制和隔离对中国大学生的睡眠质量产生了重大影响。本研究旨在探讨体育活动对大学生睡眠质量的影响以及压力和智能手机成瘾的中介作用。
选取274名符合条件的大学生（146名男性和128名女性）进行调查。采用国际体力活动问卷简表、压力感知量表、智能手机成瘾量表和匹兹堡睡眠质量指数来评估大学生的体育活动水平、压力、智能手机成瘾和睡眠质量。数据分析依次进行描述性统计、相关性分析和链式中介效应检验。
研究结果显示：（1）大学生的体育活动与压力、智能手机成瘾和睡眠质量之间存在显著负相关（ = -0.216， < 0.001； = -0.224， < 0.001； = -0.259， < 0.001）；（2）压力和智能手机成瘾在体育活动与睡眠质量的关系中起独立中介作用；（3）压力和智能手机成瘾在体育活动与睡眠质量的关联中起链式中介效应。
本研究加深了我们对体育活动如何提高睡眠质量的理解，同时强调减轻压力水平和缓解智能手机成瘾是预防大学生睡眠问题的有效策略。
