abstract = "PURPOSE: To determine the myopia prevalence in a Danish cohort aged 16-17 years and its relation to physical activity and use of screen-based electronic devices.METHODS: The Copenhagen Child Cohort 2000 Eye Study is a prospective, population-based, observational study. Information about use of screen devices and physical activity was obtained using questionnaires. Myopia was defined as non-cycloplegic subjective spherical equivalent refraction ≤-0.50 D in right eye.RESULTS: We included 1443 participants (45{\%} boys) with a median age (±IQR) of 16.6 years (±0.3). The prevalence of myopia was 25{\%} (CI95{\%} 23-28, n = 360) with no differences between sexes (p = 0.10). The odds ratio (OR) for myopia was 0.57 (CI95{\%} 0.42-0.76, p = 0.0002) in participants physically active 3-6 hr/week (n = 502) and 0.56 (CI95{\%} 0.42-0.76, p = 0.0002) if active >6 hr/week (n = 506), both compared with participants physically active <3 hr/week (n = 396). The use of screen devices >6 hr/day was associated with increased OR for myopia compared with screen device use <2 hr/day in both weekdays (OR = 1.95, CI95{\%} 1.16-3.30, p = 0.012) and weekends (OR = 2.10, CI95{\%} 1.17-3.77, p = 0.013).CONCLUSION: In this cohort of healthy 16-17-year olds, lower physical activity and more use of screen devices contributed significantly to the observed 25{\%} prevalence of myopia with a roughly doubled risk of having myopia if physically active <3 hr/week or if using screen devices >6 hr/day. Our results support physical activity being a protective factor and near work a risk factor for myopia in adolescents.",
