Abstract

Abstract

Objective To investigate the current status of refractive errors and insufficient hyperopia reserve in preschool children aged 3-6 years in Hefei and to analyze influencing factors, so as to provide a scientific basis for formulating targeted myopia prevention policies and comprehensive interventions. Methods In May 2022, a stratified cluster random sampling method was used to select 897 preschool children from 8 kindergartens across four districts (Baohe, Yaohai, Shushan, and Economic and Technological Development Zone) in Hefei, and Children's Visual Health-related Behavior Assessment Scale was used to collect personal information and environmental factors. Pre- and post-cycloplegic refraction tests were conducted to assess insufficient hyperopic reserve and refractive development levels. Group comparisons were conducted using χ² test, t-test or analysis of variance. Multivariate regression analysis was performed to identify key factors influencing hyperopic reserve, axial length and spherical equivalent in preschool children. Results The detection rates of refractive errors among preschool children were 6.8% for hyperopia, 1.6% for myopia, and 11.1% for astigmatism. Notably, the prevalence of myopia was significantly higher in boys (2.3%) than in girls (0.7%) (χ²=3.88, P < 0.05). Additionally, 8.8% of the children exhibited insufficient hyperopic reserve. The results of multiple regression analysis showed that preschool children with high myopia in the father, high myopia in the mother, longer daily duration of near work, and longer daily electronic product use time had increased risks of axial growth (β=0.12, 0.09, 0.15, 0.11), SE reduction (β=-0.10, -0.07, -0.18, -0.13), and insufficient hyperopic reserve (OR=1.87, 2.22, 1.40, 1.28) (P < 0.05). While, preschool children with longer sleep time and daily outdoor activity duration had lower risks of axial growth (β=-0.11, -0.10), SE reduction (β=0.39, 0.51), and insufficient hyperopia reserve (OR=0.54, 0.51) in preschool children (P < 0.05). Conclusions The rates of refractive errors and insufficient hyperopia reserve in preschool children in Hefei are relatively low, which are influenced by many factors. Parents, kindergartens and relevant departments should implement early vision monitoring and intervention for preschool children, and cultivate their scientific eye-use habits.
