Abstract:
Objective To evaluate the changes in the incidence of neural tube defects(NTDs)in Shaanxi province from 2003 to 2022,investigate the diagnosis time and outcomes of defective infants,and pre-dict the incidence of NTDs in Shaanxi province from 2023 to 2025,thereby providing a basis for improving the birth defects surveillance system.Methods Data were collected from all the perinatal infants from 28 weeks of gestation to 7 days after birth in all the hospitals with obstetrical department in Shaanxi province during 2003-2022.The changes in the incidence of NTDs from 2003 to 2022 were analyzed based on the birth defects surveil-lance system.Results A total of 1 106 483 perinatal infants in Shaanxi province from 2003 to 2022 were surveyed,among which NTDs occurred in 848 perinatal infants,with an incidence of 7.66/10 000.The incidence was the highest(48.02/10 000)in 2005 and the lowest(0.57/10 000)in 2022.The NTDs in Shaanxi province were mainly spina bifida(55.90%),which was followed by anencephaly(25.71%)and encephalocele(18.40%).The incidences of the three declined with fluctuations(P<0.001).The results of the Joinpoint analysis showed that the incidence of NTDs decreased slowly with the annual percentage change of-4.04 from 2003 to 2014 and declined rapidly with the annual percentage change of-28.05 from 2014 to 2022.From 2003 to 2022,the aver-age proportion of prenatal diagnosis of NTDs in Shaanxi province was 72.88%.Dead fetus(61.91%)was the main birth outcome,followed by live birth(26.77%),stillbirth(8.73%),and death within seven days after birth(2.59%).The incidence of NTDs in Shaanxi province from 2023 to 2025 were predicted by the GM(1,1)model as 0.49/10 000,0.41/10 000,and 0.35/10 000,respectively.Conclusions The incidence of NTDs in Shaanxi province declined significantly during 2003-2022,especially in a rapid manner after 2014.Dead fetus was the primary outcome of perinatal infants with NTDs,followed by live birth.
