This study investigated the relationship between near work hours and myopia in Korean adults.
We used data from the 2021 Korean National Health and Nutrition Examination Survey. Associations between near work time, physical activity, and myopia were assessed using chi-square tests and multiple logistic regression analyses.
The overall prevalence of myopia was 60.2% in adults aged 19-59 years. The prevalence of myopia was 46.2% for individuals who used smart devices for less than one hour per day, while it was 68.0% for those who used smart devices for more than four hours. In the multiple logistic regression analysis, the odds ratio (OR) for myopia was significantly higher among individuals using smart devices for 3 hours (OR = 1.55, 95% CI = 1.08-2.23) or more than 4 hours (OR = 1.75, 95% CI = 1.27-2.42), compared to users with less than 1 hour of usage. Regarding sitting time, the OR for myopia was significantly higher in individuals who sat for more than 12 hours (OR = 1.66, 95% CI = 1.05-2.61) compared to those who sat less than 4 hours.
This study found that near work and sitting times were positively associated with myopia. Given the high prevalence of myopia and its implications for serious eye diseases, it is essential to implement measures to manage myopia. Considering the increased near work hours resulting from the COVID-19 pandemic, it is necessary to adopt supplementary measures, such as ensuring sufficient rest time for the eyes and adjusting the brightness of lights, to improve eye health.
本研究调查了韩国成年人的近距工作时长与近视之间的关系。
我们使用了2021年韩国国民健康与营养检查调查的数据。使用卡方检验和多元逻辑回归分析评估近距工作时间、身体活动与近视之间的关联。
19 - 59岁成年人的近视总体患病率为60.2%。每天使用智能设备少于1小时的个体近视患病率为46.2%，而每天使用智能设备超过4小时的个体近视患病率为68.0%。在多元逻辑回归分析中，与每天使用智能设备少于1小时的用户相比，每天使用智能设备3小时（比值比[OR]=1.55，95%置信区间[CI]=1.08 - 2.23）或超过4小时（OR = 1.75，95% CI = 1.27 - 2.42）的个体患近视的OR值显著更高。关于久坐时间，与久坐时间少于4小时的个体相比，久坐超过12小时的个体患近视的OR值显著更高（OR = 1.66，95% CI = 1.05 - 2.61）。
本研究发现近距工作和久坐时间与近视呈正相关。鉴于近视的高患病率及其对严重眼部疾病的影响，采取措施管理近视至关重要。考虑到新冠疫情导致近距工作时间增加，有必要采取补充措施，如确保眼睛有足够的休息时间以及调整灯光亮度，以改善眼部健康。
