Clinical and Epidemiologic Research Time Outdoors and Physical Activity as Predictors of Incident Myopia in Childhood: A Prospective Cohort Study
نویسندگان
چکیده
METHODS. Participants in the Avon Longitudinal Study of Parents and Children (ALSPAC) were assessed by noncycloplegic autorefraction at ages 7, 10, 11, 12, and 15 years, and classified as myopic ( -1 diopters) or as emmetropic/ hyperopic (‡-0.25 diopters) at each visit (N 1⁄4 4,837–7,747). Physical activity at age 11 years was measured objectively using an accelerometer, worn for 1 week. Time spent outdoors was assessed via a parental questionnaire administered when children were aged 8–9 years. Variables associated with incident myopia were examined using Cox regression.

Time outdoors and physical activity as predictors of incident myopia in childhood: a prospective cohort study.
PURPOSE Time spent in "sports/outdoor activity" has shown a negative association with incident myopia during childhood. We investigated the association of incident myopia with time spent outdoors and physical activity separately. METHODS Participants in the Avon Longitudinal Study of Parents and Children (ALSPAC) were assessed by noncycloplegic autorefraction at ages 7, 10, 11, 12, and 15 yea...

Invest Ophthalmol Vis Sci. 2014;55:8550–8558. DOI:10.1167/iovs.14-15839 PURPOSE. More time outdoors is associated with a lesser risk of myopia, but the underlying mechanism is unclear. We tested the hypothesis that 25-hydro...
متن کاملTime Outdoors at Specific Ages During Early Childhood and the Risk of Incident Myopia
Purpose Time outdoors during childhood is negatively associated with incident myopia. Consequently, additional time outdoors has been suggested as a public health intervention to reduce the prevalence of myopia. We investigated whether there were specific ages during early childhood when the time outdoors versus incident myopia association was strongest. Methods Children participating in the ...
متن کاملDoes vitamin D mediate the protective effects of time outdoors on myopia? Findings from a prospective birth cohort.
PURPOSE More time outdoors is associated with a lesser risk of myopia, but the underlying mechanism is unclear. We tested the hypothesis that 25-hydroxyvitamin D (vitamin D) mediates the protective effects of time outdoors against myopia. METHODS We analyzed data for children participating in the Avon Longitudinal Study of Parents and Children (ALSPAC) population-based birth cohort: noncyclop...
متن کاملTime spent in outdoor activities in relation to myopia prevention and control: a meta‐analysis and systematic review
Outdoor time is considered to reduce the risk of developing myopia. The purpose is to evaluate the evidence for association between time outdoors and (1) risk of onset of myopia (incident/prevalent myopia); (2) risk of a myopic shift in refractive error and c) risk of progression in myopes only. A systematic review followed by a meta-analysis and a dose-response analysis of relevant evidence fr...
