Results: In the period of 1993-2000, there were 1 264 neural tube defects among 1 189 126 total births in 30 counties/cities in China. The overall neural tube defects rate was 10.63 per 10 000 births, and rates were higher (18.99 per 10 000 births) in the year 1993, lower (6.05 per 10 000 births) in 1998. The prevalence rates of anencephaly, spina bifida and encephalocele were 4.71 , 4.39 and 1.53 per 10 000 births respectively.
