title: [Developmental disorders in children and adolescents of the Los Ríos region, Valdivia, Chile, 2006-2008].
abstract: OBJECTIVE
  To study possible findings of factors in the antenatal, perinatal or postnatal period, in the mother or the child that may have an influence on the appearance of a developmental disorder.
  
  
  METHODS
  A Data Base of Clinical Histories from every patient with a developmental disorder (F80-F90 ICD10) was created. The patients attended the Child Psychiatric Unit at Hospital Regional of Valdivia, Chile, from August 2006 to December 2008. Total: 493 patientes (48.7% of the total of patients consulting);
  
  
  METHODS
  32 healthy patients.
  
  
  METHODS
  odds ratio (95% confidence).
  
  
  RESULTS
  The main risk factors for developing a developmental disorder (P<.005, 25% frequency in the consulting population) are: prematurity, male sex, mother with low education, early hospitalizations, and medical illnesses (all with a significant odds ratio). Also, having a mother with psychiatric illness doubles the risk of having a developmental disorder.
  
  
  CONCLUSIONS
  It requires an interdisciplinary collaborative work between neonatologists, obstetricians, child psychiatrists and the primary care to detect early children at risk.
