摘要
Objective: This nationwide population-based study aimed to examine the prospective association between near visual activities and incident myopia in Taiwanese children 7 to 12 years old over a 4-year follow-up period. Design: Prospective cohort design. Participants: There were 1958 children aged 7 to 12 years from the Taiwan 2009 National Health Interview Survey who were linked to the 2009 through 2013 claims data from the National Health Insurance system. Methods: Multivariable Cox proportional hazard models were used to estimate the associations between 3 types of near visual activities in sedentary posture, namely reading (<0.5, 0.5-0.9, >= 1.0 hours per day [h/d]), use of computer, Internet, and games (<0.5, 0.5-0.9, >= 1.0 h/d), and "cram school" attendance (<0.5, 0.5-1.9, >= 2.0 h/d), and incident myopia. Main Outcome Measures: Prevalent myopia was defined as those who had >= 2 ambulatory care claims (International Classification of Diseases code 367.1) in 2008-2009. Incident myopia was defined by those who had at least 2 ambulatory care claims (International Classification of Diseases code 367.1) during the 4-year follow-up period (2010-2013) after excluding prevalent cases. Results: Overall, 26.8% of children had myopia at baseline, and 27.7% of those without myopia at baseline developed incident myopia between 2010 and 2013. On average, they spent 0.68 +/- 0.86 h/d on computer/Internet use, 0.63 +/- 0.67 h/d on reading, and 2.78 +/- 3.53 h/d on cram school. The results showed that children attending cram schools >= 2 h/d (hazard ratio, 1.31; 95% confidence interval, 1.03-1.68) had a higher risk of incident myopia. The effects of these activities remained similar in sensitivity analyses. Conclusions: Cram school attendance for >= 2 h/d may increase the risk of children's incident myopia. This effect may be due to increased near visual activity or reduced time outdoors. (C) 2018 by the American Academy of Ophthalmology
