Students from Grade 4 to Grade 12 (aged 9-19 years) were invited to participate. A trained professional conducted clinical assessments to evaluate DED, and participants completed self-administered questionnaires to report their sleep behaviors. Sleep quality was assessed by an item from Pittsburgh Sleep Quality Index. Chi-square tests and independent-samples t-tests were used to compare sociodemographic characteristics between DED and non-DED groups. Logistic regression models were applied to examine the associations of sleep duration, social jetlag, and their interaction with DED after adjusting for potential confounders.</p><p><strong>Results: </strong>The overall prevalence of DED among children and adolescents in Fengyang County was 51%. After adjusting for confounders, binary logistic regression analysis showed that students who slept less than 9 hours per night had a significantly higher likelihood of DED (<i>OR</i> = 1.37, 95% CI: 1.21-1.68), and those with social jetlag ≥1 hour also had an elevated risk of DED (<i>OR</i> = 1.28, 95% CI: 1.07-1.54). Notably, the group with sleep duration ≥ 9 h combined with social jet lag ≥ 1 h showed a significant positive association with DED after adjusting for sleep quality (<i>OR</i> = 1.77, 95% CI: 1.35-2.33).</p><p><strong>Conclusion: </strong>Both insufficient sleep duration and significant social jetlag are associated with an increased risk of DED in children and adolescents. These findings suggest the need for targeted sleep education programs in schools that emphasize not only sufficient sleep duration but also consistent sleep-wake schedules between weekdays and weekends to promote ocular health among youth.</p>","PeriodicalId":18896,"journal":{"name":"Nature and Science of Sleep","volume":"17 ","pages":"2041-2049"},"PeriodicalIF":3.4,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12415085/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145030058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
