Effect of intensive intervention for improving the referral rate among preschoolers with vision abnormalities / 中国学校卫生

ABSTRACT

Objective@#To explore effect of intensive intervention for improving the referral rate of children with visual refractive disorders, and to provide a reference for myopia prevention and control of children and adolescents.@*Methods@#A total of 4 464 preschool children were selected from Zhuanqiao county, Minghang district in Shanghai for the eyesight investigation during April to June in 2019. Stratified random cluster sampling method was used to divide 1 724 children into intervention group and (896) control group (828) depending on the type of kindergartens. The intervention group was provied with an intensive intervention, including children s vision health assessment, parental self management guidance for children s eye care, and community based eye care services, while the control group carried out routine intervention measures.@*Results@#In 2019, the incidence of visual and primary refractive screen abnormalities in preschoolers of Zhuanqiao community was 38.62%. The incidence of naked eye vision abnormalities was 4.40%, the incidence of myopia risk group, hyperopia risk group and astigmatism risk group was 37.10%, 2.20%, and 6.10 %, respectively. After the intervention, the referral rate of the intervention group (68.75%) was significantly higher than that of the control group (17.15%)( χ 2=465.09, P <0.01). The differences between two groups were statistically significant in choosing the hospital for treatment ( χ 2=10.01, 51.51, 15.40, 27.79, 19.96, 24.24, P <0.01).@*Conclusion@#The vision and refractive status of preschoolers worths further attention. Intensive intervention can improve the referral rate for children with screened vision abnormalities, which facilitates the prevention and early diagnosis of vision problems among preschoolers.
