- Myopia has a multifactorial etiology, although environmental factors are predominant in determining its current patterns.
- Currently, associations between near work activities and myopia have not been consistently observed.
- Therefore, a systematic review was performed to quantify the effect of near work activities on myopia in children.
- Relevant articles published between 1989 and 2014 were identified in MEDLINE, Embase, and the Cochrane Library, and the citation lists were reviewed.
- Twelve cohort studies and 15 cross-sectional studies were included (25,025 children aged between 6 and 18 years).
- The I2 statistic was used to assess heterogeneity. Study-level data were pooled using a random-effects model or a fixed-effects model (when less than 5 studies were included).
- The systematic review found that more time spent on near work activities was associated with higher odds of myopia (odds ratio [OR] = 1.14; 95% confidence interval [CI] = 1.08–1.20) and that the odds of myopia increased by 2% (OR:1.02; 95% CI = 1.01–1.03) for every one diopter-hour (hr) more of near work per week.
- Therefore, the development of a strategy to reduce the impact of near work on myopia would be important for preventing myopia in children.
