Abstract：
BACKGROUND:While physical activity has been reported to positively affect stress and sleep quality, less is known about the potential relationships among them. The present study aimed to investigate the mediating effect of stress on the association between physical activity and sleep quality in Chinese college students, after controlling for age, nationality, and tobacco and alcohol use. PARTICIPANTS:The sample comprised 6973 college students representing three Chinese universities. METHODS:Physical activity, perceived stress, and sleep quality were respectively measured using the International Physical Activity Questionnaire-Short Form (IPAQ-SF), Perceived Stress Scale-10 Items (PSS-10), and Pittsburgh Sleep Quality Index (PSQI). RESULTS:Mediating effects of perceived stress on the association between physical activity and sleep quality were observed in males and females, with 42.4% (partial mediating effect) and 306.3% (complete mediating effect) as percentages of mediation, respectively. CONCLUSION:The results of this study may provide some suggestions that physical activity could improve sleep by aiding individuals in coping with stress and indicate that stress management might be an effective non-pharmaceutical therapy for sleep improvement.
