Abstract
Objective To study the influence of near-work and outdoor activities on myopia progression in school children.Methods Eighty 7-11-year-old school children with myopia were randomly assigned into an intervention group (n =41 ) and a control group (n =39).The children in the intervention group did near- and middle-vision activities less than 30 hrs per week and more outdoor activities than 14-15 hrs per week.Myopia progression was observed regularly over 2 years after which ophthalmologists administered questionnaires regarding near-vision work (reading, writing and using computer), middle-vision work (watching TV and extracurricular learning activities ), outdoor activities, using nature light, wearing glasses, etc.Results The annual mean myopia progression (0.38 ±0.15 D) in the intervention group was significantly lower than that in the control group (0.52 ±0.19 D; P ＜0.01 ).The children in the two groups spent similar amounts of time in near-vision activities, but the children in the intervention group spent less time in middle-vision activities ( P ＜ 0.01 ) and more outdoor activities ( 13.7 ± 2.4 vs 6.2 ± 1.6 hrs/wk; P ＜ 0.01 ).When considering all children in the study, there were 4 factors that significantly correlated with less myopia progression: more outdoor activities, more time spent wearing glasses, more time spent in natural light and less time using a computer.When analyzing the intervention group separately, more outdoor activity was inversely correlated with myopia progression (t = -2.510 ,P ＜0.05 ).Separate analysis of the control group indicated that more time wearing glasses was correlated with less myopia progression ( t = - 3.115, P ＜ 0.05 ).Conclusions Myopia progression in school children may be slowed by more outdoor activities, more time spent in natural light and more time wearing corrective glasses.关键词
