Negative emotions among college students, particularly those who are physically weak, have raised concerns due to their impact on mental health and, in some cases, the development of suicidal tendencies. Limited physical activity exacerbates these mental health risks. It is essential to explore the relationship between physical activity, sleep quality, and negative emotions in this population.
To examine the relationship between physical activity, sleep quality, and negative emotions among physically weak college students.
A stratified sampling approach was employed to select 1,248 first- and second-year students from a university in Beijing. Physical activity levels were assessed using the International Physical Activity Questionnaire Short Form (IPAQ-SF), sleep quality was evaluated with the Pittsburgh Sleep Quality Index (PSQI), and depression, anxiety, and stress were measured via the Depression Anxiety Stress Scales (DASS-21). Chi-square tests and logistic regression analyses were conducted to explore associations among these variables. Additionally, a mediation effect model was utilized to examine the mediating role of sleep quality between physical activity and negative emotions.
The incidence of negative emotions was significantly higher among physically weak college students compared to their peers ( < 0.05). Binary logistic regression results indicated that increased physical activity intensity was associated with a lower occurrence of negative emotions ( = 0.514, : 0.367-0.719). Linear regression analysis showed a significant positive correlation between higher physical activity intensity and better sleep quality ( = -0.185, < 0.01). The mediation effect analysis revealed that sleep quality partially mediated the relationship between physical activity and negative emotions, with total, direct, and indirect effects of -0.67, -0.60, and -0.097, respectively. Sleep quality accounted for 14.6% of the total effect in this relationship.
The incidence of negative emotions among physically weak college students is significantly higher than among their peers and increased physical activity intensity is significantly associated with a decrease in negative emotions. Sleep quality plays a crucial mediating role in this relationship. These findings provide a theoretical foundation for developing targeted mental health interventions for physically weak college students and highlight the importance of sleep quality in improving their mental health.
大学生中的负面情绪，尤其是身体虚弱的学生，因其对心理健康的影响以及在某些情况下自杀倾向的发展而受到关注。有限的体育活动会加剧这些心理健康风险。探索该人群中体育活动、睡眠质量和负面情绪之间的关系至关重要。
研究身体虚弱的大学生中体育活动、睡眠质量和负面情绪之间的关系。
采用分层抽样方法，从北京一所大学选取1248名大一和大二学生。使用国际体力活动问卷简表（IPAQ-SF）评估体育活动水平，用匹兹堡睡眠质量指数（PSQI）评估睡眠质量，通过抑郁焦虑压力量表（DASS-21）测量抑郁、焦虑和压力。进行卡方检验和逻辑回归分析以探索这些变量之间的关联。此外，利用中介效应模型检验睡眠质量在体育活动和负面情绪之间的中介作用。
身体虚弱的大学生中负面情绪的发生率显著高于同龄人（<0.05）。二元逻辑回归结果表明，体育活动强度增加与负面情绪发生率降低相关（=0.514，：0.367-0.719）。线性回归分析显示，体育活动强度越高与睡眠质量越好之间存在显著正相关（=-0.185，<0.01）。中介效应分析表明，睡眠质量部分中介了体育活动与负面情绪之间的关系，总效应、直接效应和间接效应分别为-0.67、-0.60和-0.097。睡眠质量在这种关系中占总效应的14.6%。
身体虚弱的大学生中负面情绪的发生率显著高于同龄人，体育活动强度增加与负面情绪减少显著相关。睡眠质量在这种关系中起关键中介作用。这些发现为针对身体虚弱的大学生制定有针对性的心理健康干预措施提供了理论基础，并强调了睡眠质量对改善他们心理健康的重要性。
