title: [Origin of neonatal morbidity].
abstract: OBJECTIVE
  To identify the different diseases that have an influence on neonatal morbidity, with the purpose of suggesting rules that prevent and avoid it.
  
  
  METHODS
  We made a clinical study of the mothers and new-born babies that were admitted at the Tocosurgery and Neonatology Department for presenting a disease that requires its treatment and follow-up in such department. The study was retrospective, transversal, descriptive and observational, and it was made from January 1st to April 30th 1999 at the Hospital General de Zona número 1, IMSS.
  
  
  RESULTS
  The morbidity was of 20% and it was more frequent in the masculine gender (53%) and in babies with 2,500 to 3,000 g (60%). Among the most common diseases we found: respiratory difficulty (10%), macrosomia (15%), early membrane rupture (12%), hypotrophy (11%), and children of mothers with Rh negative blood (10%).
  
  
  CONCLUSIONS
  The analysis of the morbidity obligues to identify, through the identification of the risk factors during pregnancy, labor and delivery, the patients in high risk in order to prevent and avoid neonatal morbidity, as well as to obtain better results in the new-born.
