Abstract:Objective: To explore the refractive status along with relevant factors during the fetal and infancy period in 9-month-old infants, and to provide evidence for early prevention and intervention of refractive errors. Methods: This study analyzed refractive screening data accumulated by the Minhang District Maternal and Child Health Care Institution, Shanghai, from 2012 to 2019. In all, 16 746 infants aged 9 months were included in the description of refractive status. Relevant factors before 9 months of age were collected by child health examination records and questionnaire survey data. Chi-square tests and multivariate regression models were used to analyze the association of factors during the fetal and infancy periods in 9-month-old infants with suspicious refractive errors. Results: The P5-P95 of the refractive sphere for infants aged 9 months was +0.50 D-+3.00 D, and the P5 of the refractive cylinder for infants aged 9 months was -2.50 D. Detection rates of suspected myopia, hyperopia, astigmatism, and anisometropia were 13.46%, 11.13%, 25.58%, 8.29%, respectively. Birth during the winter and frequent contact with electronic devices increased the risk of suspected myopia (adjusted OR were 1.35, 1.55 respectively). Birth during the summer or autumn, prematurity and a physique greater than the P80 quantile at 9 months of age increased the risk of suspected hyperopia (adjusted OR were 1.67, 1.62, 1.80, 1.22 respectively). Birth during the summer, a physique greater than the P80 quantile and artificial feeding at 9 months of age increased the risk of suspected astigmatism (adjusted OR were 1.92, 1.42, 1.19, respectively). Outdoor activities of more than 0.5 h per day decreased the risk of suspected refractive errors (adjusted OR=0.711- 0.803). Conclusion: Detection rates of suspected refractive errors in infants aged 9 months are between 8% and 25%, among which astigmatism is most significant. Infants with high-risk factors such as prematurity, parents with refractive errors and large physique should be the focus of refractive screening and follow-up.
