Comparison of Solar Radiation and Myopia Occurrence in South Korean Children.

Abstract:

Purpose:To investigate the association between regional solar radiation and myopia occurrence in South Korean children. Materials and Methods: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. Results:In the entire cohort of 1218 participants, solar radiation and sunshine duration were significantly associated with the mean spherical equivalent (P=0.001 and P=0.014, B = 0.088 and B = 0.069, respectively) and solar radiation was significantly associated with myopia prevalence (P=0.008). And, a negative but not statistically significant association between sunshine duration and myopia prevalence was observed (P=0.064, respectively). Conclusions:Solar radiation and sunshine duration are associated with the mean spherical equivalent and myopia prevalence in South Korean children.
