title: [Transient tachypnea of the newborn, obstetric and neonatal risk factors].
abstract: OBJECTIVE
  To identify the obstetrics and neonatal risk factors associated with transient tachypnea of the newborn.
  
  
  METHODS
  Case-control study of 110 neonates with transient tachypnea and 110 newborns controls, between May and October 2000, in the Hospital Civil de Guadalajara Dr. Juan I. Menchaca. The diagnosis of transient tachypnea was done by clinical and radiology data and exclusion of the other causes of respiratory distress. The exposure was documented by a direct interview to the mother and clinical information of the clinical expedient. The association was measured with the odds ratios and confidence interval of 95%.
  
  
  RESULTS
  The frequency of transient tachypnea was of 2 percent newborn alive. The risk factors that were associated with transient tachypnea was: low Apgar score at minute (OR: 33.74, CI 95%: 4.73-681.52), premature rupture of amniotic membranes (OR: 3.65, CI 95%: 1.53-8.90), cesarean section (OR: 2.01, CI 95%: 1.14-3.57) and masculine gender (OR: 2.02, CI 95%: 1.14-3.60). It was more frequent in the cases the antecedent of diabetes mellitus and bronchial asthma.
  
  
  CONCLUSIONS
  The results suggest that it's necessary to improve the obstetrics surveillance to diminish the frequency of low Apgar score and risk factors associated with transient tachypnea of the newborn.
