Abstract:
Objective:To understand the home reading-writing levels among children and adolescents in Shanghai after school, and to explore its association with screening myopia, so as to provide a scientific basis for the prevention and control of myopia.
Methods:From April to December 2024, 641 primary and middle school students were recruited from 2 urban schools and 1 rural school in Shanghai to participate in the survey. An illuminance meter was used to measure the illuminance of home reading-writing activities after school. Screening myopia was determined through visual acuity examination and refractive detection under non ciliary muscle paralysis conditions among children and adolescents. A binary Logistic regression model was used to analyze the association between home reading-writing illuminance and screening myopia.
Results:The detection rate of screening myopia among children and adolescents in Shanghai was 59.9%. The median home reading-writing illuminance after school was 340.9(112.2, 753.5) lx, and 45.4% was found of less than 300 lx. The family illuminance in the primary school stage [432.0 (136.9, 837.0) lx] was higher than that in the junior high school stage [113.1(53.7, 375.1) lx], and main urban area group [503.9 (212.6, 969.5) lx] was higher than that in the rural group [141.6 (53.7, 416.9) lx], the differences were statistically significant (Z=-7.56, -9.95,both P<0.05). The results of Logistic regression analysis showed that compared with the family illuminance of 150-500 lx, children and adolescents with family illuminance<150 and >500 lx had increased risks of screening myopia detection[OR(95%CI)=1.56(1.01-2.42), 1.74(1.15-2.62),both P<0.05].
Conclusions:The home reading-writing illuminance after school is suboptimal. Both excessively low and high home reading-writing illuminance levels are associated with screen-detected myopia. It is necessary for children and adolescents to improve lighting conditions during evening reading-writing activities, and strengthen health education according to different regions and school stages.
