title: [Present situation of congenital defects in five counties (cities) of Gansu province in 2009 - 2010].
abstract: OBJECTIVE
  To understand the situation of congenital defects' in five counties/cities in Gansu province so as to provide scientific evidence for the development of effective interventions.
  
  
  METHODS
  General information was collected on all the neonates who were born in Dunhuang city, Jingchuan county, Hui county, Weiyuan county and Yongjing county in Gansu province between Oct. 1(st), 2009 to Sep. 30(th), 2010, with all of their gestational age above 28 weeks. Neonates would include live birth, dead fetus and still birth.
  
  
  RESULTS
  The overall incidence of congenital defects was 7.49‰ in the five counties/cities in Gansu province in 2009. Ranking order in the top three showed as congenital heart disease, pigmented nevus and limb deformity. Disease with the highest mortality was congenital heart disease (0.79‰). The incidence of congenital defects was 8.35‰ in 2010 with the ranking order of the top three as congenital heart disease, neural tube defects/pigmented nevus and hydrocephalus. Diseases having the highest mortality was congenital heart disease (1.10‰). Different incidence rates on congenital defects were seen in related areas, with the highest incidence as 14.65‰ in Dunhuang city. Hui county had the lowest incidence-3.28‰.
  
  
  CONCLUSIONS
  Different incidence of congenital defects were seen in respective areas in Gansu province, with the change of ranking orders. Different strategies should be developed differently depending on the current states of congenital defects in respective areas, according to the three-grade prevention model, to reduce the occurrence of congenital defects.
