To investigate the association between regional solar radiation and myopia occurrence in South Korean children.
A population-based cross-sectional study using data of 1218 children aged 7-9 years from the Korea National Health and Nutritional Examination Survey was conducted from January 1, 2008, to December 31, 2012. Myopia prevalence and the mean spherical equivalent were estimated; myopia was defined as spherical equivalent refraction <-1.5 D. Data regarding solar radiation and sunshine duration were collected from 21 national monitoring stations in South Korea. Multiple logistic regression analyses and multiple linear regression analyses were used to evaluate the associations. However, the most important covariate, the time spent outdoors, was not measured and could not be used.
In the entire cohort of 1218 participants, solar radiation and sunshine duration were significantly associated with the mean spherical equivalent (=0.001 and =0.014, = 0.088 and = 0.069, respectively) and solar radiation was significantly associated with myopia prevalence (=0.008). And, a negative but not statistically significant association between sunshine duration and myopia prevalence was observed (=0.064, respectively).

探讨韩国儿童局部太阳辐射与近视发生之间的关联。
采用韩国国家健康与营养检查调查中1218名7至9岁儿童的数据进行基于人群的横断面研究，研究时间为2008年1月1日至2012年12月31日。估算近视患病率和平均球镜当量；近视定义为球镜当量屈光度<-1.5D。从韩国21个国家监测站收集有关太阳辐射和日照时长的数据。采用多重逻辑回归分析和多重线性回归分析来评估这些关联。然而，最重要的协变量——户外活动时间未被测量，无法使用。
在1218名参与者的整个队列中，太阳辐射和日照时长分别与平均球镜当量显著相关（分别为=0.001和=0.014，=0.088和=0.069），且太阳辐射与近视患病率显著相关（=0.008）。此外，观察到日照时长与近视患病率之间存在负相关，但无统计学意义（分别为=0.064）。
