Associations between recreational screen time and insomnia symptoms among college stu-dents:the mediating roles of addictive behaviors
摘要
Abstract
Objective:To examine the associations between recreational screen time and insomnia symptoms among college students,and to explore the mediating roles of internet gaming addiction and social network addic-tion.Methods:From October to November 2025,a multistage sampling method was used to conduct a question-naire survey among 2,853 first-year undergraduate students from six universities in Shanghai.Recreational screen time was assessed using self-reported daily duration of screen-based entertainment activities.Internet gaming ad-diction and social network addiction were measured using the internet gaming disorder scale and the social net-work addiction tendency scale,respectively.Insomnia symptoms were evaluated using the insomnia severity in-dex.Multivariable logistic regression models were applied to analyze the associations between recreational screen time,addictive behaviors,and insomnia symptoms.The results of the structural equation model was fur-ther conducted to test the mediating roles of internet gaming addiction and social network addiction.Results:A total of 529 students reported insomnia symptoms.Recreational screen time(＜6 h/d:OR=0.715,95%CI:0.560-0.902;6-8 h/d:OR=0.592,95%CI:0.463-0.755),internet gaming addiction(OR=1.197,95%CI:1.148-1.249),and social network addiction(OR=1.126,95%CI:1.106-1.146)were all associated with insomnia symptoms(all P＜0.001).After simultaneously including recreational screen time,internet gaming addiction,and social net-work addiction in the model,the association between some subgroups of recreational screen time and insomnia symptoms was not statistically significant(＜6 h/d:OR=1.110,95%CI:0.865-1.424,P=0.411).The results of the structural equation model indicated that recreational screen time was indirectly associated with insomnia symp-toms through internet gaming addiction(β=0.020,95%CI:0.010-0.030,P＜0.001)and social network addiction(β=0.061,95%CI:0.040-0.083,P＜0.001).The standardized total indirect effect β was 0.081(95%CI:0.056-0.108,P＜0.001),whereas the direct effect of recreational screen time on insomnia symptoms was not statisti-cally significant(P=0.928).Conclusion:The associations between recreational screen time and insomnia symp-toms among college students are mainly mediated by addictive behaviors,with internet gaming addiction and so-cial network addiction playing a key mediating role in this relationship.关键词
