title: [Screening and follow-up treatment of 160 046 neonates with congenital adrenal hyperplasia in Ningxia, China].
abstract: OBJECTIVE
  To investigate the incidence of congenital adrenal hyperplasia (CAH) and treatment outcomes in neonates in Ningxia, China.
  
  
  METHODS
  The clinical data of CAH screening for 160 046 neonates who were born in midwifery institutions in Ningxia from July 2014 to March 2016 were analyzed.
  
  
  RESULTS
  Among the 160 046 neonates who underwent CAH screening, 70 (0.044%) obtained a positive result and 11 were diagnosed with CAH; the incidence rate of CAH was 1/14 550 (0.069‰). Among the 11 neonates diagnosed with CAH, 9 had the salt wasting type (2 died) and 2 had simple virilization. The 9 neonates were given glucocorticoids immediately once diagnosed and all of them achieved good growth and development.
  
  
  CONCLUSIONS
  The incidence of neonatal CAH in Ningxia is 1/14 550. It is very necessary to carry out CAH screening in Ningxia, and active treatment can improve the prognosis of neonates with CAH.
