Knowledge about the prevalence and the modifiable risk factors associated with myopia development will help in planning cost-effective strategies to prevent its progression in India. PURPOSE: The purpose of this study was to assess the prevalence and associated behavioral risk factors of myopia in schoolchildren in Gurugram, Haryana, in north India. METHODS: This cross-sectional study was conducted on schoolchildren (aged 5 to 15 years) from two private schools in Gurugram. Visual acuity was measured using the Early Treatment Diabetic Retinopathy Study chart. Myopia was defined as the spherical equivalent refractive error of at least −0.50 D in the better eye. Information on the child's habits and lifestyle, study hours, hours of playing video games, and outdoor playtime were obtained using a questionnaire. Association of behavioral risk factors was analyzed for children with and without myopia, and adjusted odds ratio (OR) for each factor was estimated. RESULTS: A total of 1234 children (mean ± SD age, 10.5 ± 3 years; 59% boys) were screened. Myopia prevalence was found to be 21.1% (n = 261; mean ± SD age, 11 ± 2 years; 52% boys). The mean ± SD myopic spherical error was −1.94 ± 0.92 D. The prevalence of myopia was found to be higher (27%; 95% confidence interval, 23 to 30.6; OR, 3.19 [2.13 to 4.76]) among older children (9 to 12 years). Prevalence of myopia was more in boys (25%; 95% confidence interval, 21.1 to 28.8) compared with girls (P < .01). A positive association of presence of myopia was observed with children studying more than 4 hours per day (P < .008) and with children playing computer/video/mobile games more than 2 hours per day (P < .001). A protective effect was observed in children with outdoor activities/play for more than 1.5 hours per day (OR, 0.01 [0.00 to 0.06]). CONCLUSIONS: Myopia is a major public health concern, and its prevalence is increasing rapidly among schoolchildren in India. There is a pressing need to develop cost-effective strategies to prevent this cause of vision impairment, which can be easily treated with optical interventions.
