This study aimed to investigate the association between self-reported sleep duration and visual impairment (VI) in Korean adults.
This population-based, cross-sectional study examined ophthalmologic data of 16,374 Koreans aged 19 years and older from the 2010-2012 Korea National Health and Nutrition Examination Survey (KNHNES V). VI data (best-corrected distance visual acuity worse than 0.5 logMAR in the better-seeing eye) were obtained from direct ophthalmologic examinations, and data on self-reported sleep duration (≤5, 6, 7, 8, or ≥9 h/night) were obtained using questionnaires. Multiple logistic regression analysis was conducted to examine the association between self-reported sleep duration and VI, and we also adjusted for possible covariates.
The weighted VI prevalences (95% CIs) were 1.23% (0.70-1.76), 0.40% (0.10-0.70), 0.18% (0.04-0.31), 0.42% (0.26-0.58), and 0.66% (0.25-1.07) for participants who slept ≤5, 6, 7, 8, and ≥9 h/night, respectively. Even after adjusting for demographic factors (age and sex), lifestyle factors (household income, occupation, smoking status, regular exercise, and suicidal thoughts), and medical factors (diabetes, hypertension, stroke, and history of ocular surgery), greater risk of VI was found in the ≤5 h/night (OR = 3.23, 95% CI: 1.43-7.31) and ≥9 h/night (OR = 2.56, 95% CI: 1.03-6.41) groups, compared to the 7 h/night group.
In Korean adults, self-reported sleep duration and VI exhibited a U-shaped association. Both very short (≤5 h/night) and very long (≥9 h/night) sleep durations were significantly associated with increased VI.
本研究旨在调查韩国成年人自我报告的睡眠时间与视力损害（VI）之间的关联。
这项基于人群的横断面研究检查了2010 - 2012年韩国国家健康与营养检查调查（KNHNES V）中16374名19岁及以上韩国人的眼科数据。视力损害数据（较好眼最佳矫正远视力低于0.5 logMAR）通过直接眼科检查获得，自我报告的睡眠时间数据（≤5、6、7、8或≥9小时/晚）通过问卷调查获得。进行多因素逻辑回归分析以检查自我报告的睡眠时间与视力损害之间的关联，并且我们还对可能的协变量进行了调整。
每晚睡眠时间≤5、6、7、8和≥9小时的参与者的加权视力损害患病率（95%可信区间）分别为1.23%（0.70 - 1.76）、0.40%（0.10 - 0.70）、0.18%（0.04 - 0.31）、0.42%（0.26 - 0.58）和0.66%（0.25 - 1.07）。即使在调整了人口统计学因素（年龄和性别）、生活方式因素（家庭收入、职业、吸烟状况、定期锻炼和自杀念头）以及医学因素（糖尿病、高血压、中风和眼部手术史）之后，与每晚睡7小时的组相比，每晚睡≤5小时（比值比[OR]=3.23，95%可信区间：1.43 - 7.31）和≥9小时（OR = 2.56，95%可信区间：1.03 - 6.41）的组中发现视力损害风险更高。
在韩国成年人中，自我报告的睡眠时间与视力损害呈U形关联。极短（≤5小时/晚）和极长（≥9小时/晚）的睡眠时间均与视力损害增加显著相关。
