ABSTRACT

Objective:To retrospectively characterize the perinatal birth defects in the latest 5 years in Minhang District of Shanghai， and provide the evidence to improve the preventive strategies. Methods:The data of perinatal birth defects was retrieved from “Shanghai information reporting system for children with birth defects and disabilities” ，which was recorded by five sentinel hospitals in Minhang District from January 2014 to December 2018. Average proportion of perinatal birth defects in the recent 5 years， annual variation， comparison with municipal data in the same period， difference between registered population and migrant population， difference between male and female， and common birth defects were determined. Results:The average proportion of perinatal birth defects in the recent 5 years was determined to be 6.24‰， which increased from 5.32‰ in 2014 to 7.90‰ in 2018. It was lower than the municipal proportion in Shanghai with an average of 11.02 ‰ （from 9.7 ‰ in 2014 to 14.00 ‰ in 2018）. The proportion was higher in resident population （9.15‰） than that in migrant population （5.57‰）. In addition， the proportion was higher in male infants （6.81‰） than that in female infants （5.59‰）. The first two common defects were congenital heart disease and polydactyly， while cleft lip and cleft lip with palate showed a decreasing trend. Conclusion:In the recent 5 years， the proportion of birth defect increases， which is consistent with the whole city. There remain challenges in the maternal and children healthcare.
