Abstract：Objective To investigate the prevalence of refractive anomalies and its affecting factors in 4237 children aged 7-12 years in Wuxi City. Methods A total of 4237 children were randomly selected from November to December 2018 to study in Wuxi Hechang Primary School, Rongcheng Primary School, Taihu New Town Primary School, Pre-school Campus of Wuxi Normal Primary School and Xiaoyangguang Campus of Wuxi Normal Primary School. According to the diopter, they were divided into the normal group (n = 2362) and the abnormal group (n = 1875). The distribution of vision and prevalence of refractive anomalies in children of different ages were observed, the factors affecting children aged 7-12 years were analyzed, and a multivariate logistic regression model was established to identify the risk factors for children with refractive anomalies. Results The proportion of children aged 7-<11 years old with vision of > 0.8 was the highest, the proportion of children aged 11-<12 years old with vision of 0.5-0.6 was the highest, and the proportion of children aged 12-<13 years old with vision of 0.1-0.4 was the highest. The prevalence of refractive anomalies was highest in children aged 12- < 13 years, and lowest in children aged 7- < 8 years. Daily sleep duration, good eye habits, balanced nutrition, regular visual acuity examination, and age were associated with refractive anomalies in children aged 7-12 years (P < 0.05). Age≥9 years old, daily sleep time < 8 h, poor eye habits, nutritional imbalance and not regularly examined vision were risk factors for refractive anomalies in children aged 7-12 years old (P < 0.05). Conclusion During the prevention of refractive anomalies in children aged 7-12 years old, close attention should be paid to children′s age, sleep time, eye habits, balanced nutrition and regular visual examination, so as to take timely measures to prevent and reduce the incidence of refractive anomalies in children.
