摘　　要：目的探讨青少年休闲屏幕时间与失眠症状发生的关联。方法采用随机整群抽样方法,对成都市郫都区在校12~18岁青少年通过自我报告问卷评估研究对象上学日和周末休闲屏幕使用时间。采用失眠严重程度指数量表(ISI)评估研究对象的失眠症状。根据ISI总分分为无失眠症状组(<7分)和有失眠症状组(≥7分)。使用logistic回归模型评估休闲屏幕时间与发生失眠症状的关联。结果本研究共纳入13240名青少年,其中男生6581名(49.7%),女生6659名(50.3%);平均年龄为(15.4±1.57)岁,有51.8%的青少年平均每日休闲屏幕时间>2 h,失眠症状检出率为35.3%。Logistic回归分析结果显示,调整混杂后,青少年休闲屏幕时间>2 h是失眠症状的危险因素(OR=1.13,95%CI:1.03~1.23)。进一步按休闲屏幕时间的四分位数分组分析显示,休闲屏幕时间处于Q3(OR=1.15,95%CI:1.02~1.28)和Q4(OR=1.22,95%CI=1.08~1.39)的青少年,失眠风险显著增加,而Q2组未发现显著关联。此外,休闲屏幕时间水平与失眠之间呈现明显的剂量-反应关系(趋势性P<0.001)。在性别、地区、经济状况、独生子女及主要照顾人等亚组分析中,均未观察到明显的交互作用(P交互作用>0.05)。结论休闲屏幕时间过长显著增加青少年失眠症状风险。家长和学校应鼓励学生增加体力活动,并减少使用电子设备,以促进其身心健康。Objective To investigate the associations between leisure screen time and theinsomnia symptoms among adolescents.Methods A random cluster sampling method was used to assess leisure screen time among adolescents aged 12-18 attending schools in Pidu District,Chengdu.Participants reported their screen time on school days and weekends via self-administered questionnaires.Insomnia symptoms were collected using the Insomnia Severity Index(ISI).Adolescents were categorized into two groups based on their ISI scores:the non-insomnia group(ISI score<7)and the insomnia group(ISI score≥7).Logistic regression models,adjusted for multiple confounders,were used to estimate the association between leisure screen time and the occurrence of insomnia symptoms.Results A total of 13240 adolescents participated,comprising 6581 boys(49.7%)and 6659 girls(50.3%),with a mean age of 15.4 years(±1.57).Of these,51.8%reported an average daily leisure screen time exceeding 2 h,and the prevalence of insomnia symptoms was 35.3%.After adjusting for all confounding factors,logistic regression analysis indicated that leisure screen time>2 h was a significant risk factor for insomnia symptoms(OR=1.13,95%CI=1.03-1.23).Further analysis by quartiles of leisure screen time revealed that adolescents in Q3(OR=1.15,95%CI=1.02-1.28)and Q4(OR=1.22,95%CI=1.08-1.39)had significantly increased risks of insomnia,whereas no significant association was observed in the Q2 group.A clear dose-response relationship was observed between leisure screen time and insomnia(Ptrend<0.001).Subgroup analyses by sex,region,economic status,single child,and caretaker did not reveal significant interactions(Pinteraction>0.05).Conclusion Prolonged leisure screen time significantly increases the risk of insomnia symptoms among adolescents.Parents and schools should encourage physical activity and reduce electronic device usage to promote their well-being.
