The association between sleep duration and myopia among Chinese school-age students: mediation effect of physical activity

This study aimed to investigate the relationship between sleep duration and myopia in school-age students, as well as to observe the role of physical activity as a mediating variable in sleep duration and myopia. Using multistage stratified sampling, 26,020 school-age students in Jiangsu Province, a...

Description
Summary:This study aimed to investigate the relationship between sleep duration and myopia in school-age students, as well as to observe the role of physical activity as a mediating variable in sleep duration and myopia. Using multistage stratified sampling, 26,020 school-age students in Jiangsu Province, ages 7-18, were selected for this cross-sectional survey. Each participant completed a standardized interview in which their were asked about their vision, level of physical activity and average hours of sleep per day over the past month. Visual acuity examinations were conducted by the testing team's ophthalmology professionals and they were categorized into two groups based on pre-set criteria: myopic and non-myopic. Sleep duration was classified into 3 categories: 10 h/d. The Pearson's chi-square tests were used to examine differences in the incidence of myopia among participants. Binary multifactorial logistic regression adjusted for potential confounding variables was used to examine the relationship between myopia and a variety of factors. The mediating effects of physical activity on sleep duration and myopia were analyzed using the AMOS model. In this study, the incidence of myopia was higher in females than in males, it also increased with age. Those who slept for
