Purpose : This study was performed to evaluate the correlation between sleep duration and the prevalence of dry eyes in Korean adults over the age of 40.
Methods : Among the 16,119 adults who participated in the 7th Korean National Health and Nutrition Examination Survey, and 2,506 adults were enrolled in our study. The collected data were analyzed composite samples, with the calculations for mean, standard deviation, t-test, ANOVA. The correlation between sleep duration and dry eyes was analyzed by chi-square test.
Logistic regression analysis was performed to analyze the effect of general characteristics on dry eyes. We controlled for Variables including gender, age, education, household income, job, work time zone, BMI, smoking, and drinking.
Results : As a result of the analysis, the overall sleep duration was 7 hours. Sleep duration and dry eyes have been found to be related. As a result of logistic regression analysis of factors affecting dry eyes, dry eyes increased more in shorter than 5 hours than in 7 hours of sleep duration (OR 1.93 [95% CI: 1.38-2.71]). Dry eye increased in women than men (OR 0.40 [95% CI: 0.32-0.49]). The odds ratio increased obesity compared to low weight (OR 1.89 [95% CI: 1.11-3.19]), and dry eyes increased in more than 4 times a week on drinking (OR 2.43 [95% CI: 1.42-4.16]).
Conclusion : The association between dry eyes and sleep duration was confirmed. Therefore, it is necessary to prevent dry eyes through proper sleep duration.
