Myopia is one of the most commonly diagnosed refractive disorders worldwide. Identifying risk factors for myopia at an early age may help to characterize children who would benefit most from individualized lifestyle advice and early interventions. The influence of sleep duration on myopia risk remains controversial and thus needs to be evaluated.
A population-based cross-sectional study of Chinese school-aged children was conducted. Information on sleep duration was derived. The association between sleep duration and myopia risk was investigated by logistic regression analysis.
Myopia prevalence among 9530 Chinese school-aged children was 75.4% and decreased from 84.9%, 76.5%, 65.8%, to 61.3% along with the extension of sleep duration. Univariate logistic regression found longer sleep duration of 8-9 h (OR = 0.58, 95% CI: 0.51-0.66), 9-10 h (OR = 0.34, 95% CI: 0.30-0.39), and ≥ 10 h (OR = 0.28, 95% CI: 0.24-0.33) were protective factors for myopia in all participants (P for trend < 0.001). In the multivariate analyses, sleep duration was inversely associated with the risk of myopia, and a dose-effect relationship was observed when the analysis was split by age category.
Long sleep duration was associated with decreased risk of myopia in Chinese school-aged children.
近视是全球最常见的屈光不正诊断之一。在早期识别近视的危险因素，可能有助于确定最需要个性化生活方式建议和早期干预的儿童。睡眠时间对近视风险的影响仍存在争议，因此需要进行评估。
进行了一项基于人群的中国学龄儿童横断面研究。获取了睡眠时间信息。通过逻辑回归分析调查睡眠时间与近视风险之间的关联。
9530 名中国学龄儿童中近视的患病率为 75.4%，随着睡眠时间的延长，患病率从 84.9%、76.5%、65.8%降至 61.3%。单因素逻辑回归发现，睡眠时间较长 8-9 小时（OR=0.58，95%CI：0.51-0.66）、9-10 小时（OR=0.34，95%CI：0.30-0.39）和≥10 小时（OR=0.28，95%CI：0.24-0.33）是所有参与者近视的保护因素（P 趋势<0.001）。在多变量分析中，睡眠时间与近视风险呈负相关，且按年龄类别分层分析时观察到了剂量-效应关系。
较长的睡眠时间与中国学龄儿童近视风险降低有关。
