abstract = {BackgroundThe objectives of this study were to explore the
prevalence of neural tube defects (NTDs) in three districts
of Beijing, and to evaluate the impact of prenatal diagnosis
on the prevalence.MethodsData were collected between 2006
and 2012 from the Beijing Birth Defects Surveillance System.
P13 and P28 represent the prevalence of NTDs diagnosed from
13 weeks and 28 weeks of gestation, respectively, to 7 days
after delivery. Populations were classified as household
(permanent) and non-household (non-permanent) because
differences exist in access to health care, education, and
income, among others.ResultsThe P13 of NTDs was 11.7 per 10
000 births in the three districts, which declined from
2006–12. In addition, the prevalence of NTDs in the
non-household population was 1.7-fold higher than that among
the household population. The P13 of anencephaly, spina
bifida, and encephalocele were 5.3, 4.9, 1.6, respectively,
per 10 000 births. The P28 of NTDs only represented $29.1\%$
of P13, and this proportion decreased over the 7-year
period.ConclusionsThe prevalence of NTDs remains high in the
three districts of Beijing, and the rate was higher in the
non-household than household population. The prevalence of
birth defects would be under estimated by almost 70 per cent
if the report time was set on 28 weeks’ gestation or later
compared with report time on 13 weeks of gestation. It is
better to set the report time earlier in birth defect
surveillance in contemporary China.},
