title: [Impact of the prenatal care in the neonatal morbidity and mortality].
abstract: OBJECTIVE
  To analyze the prenatal care impact in the neonatal morbidity and mortality.
  
  
  METHODS
  Case-control cohort-nested study, among hospitalized and healthy newborns. The variables studied were: prenatal care, neonatal morbidity (respiratory distress syndrome, prematurity, low weight at birth, congenital malformations and asphyxia) and mortality, as well as mother's age, weight, height, gestation, and level of education. The statistical analysis was made through percentage, rates and standard deviation, odds ratio and chi2.
  
  
  RESULTS
  We analyzed 407 mother and newborn files divided in 2 groups: 118 hospitalized newborns (cases) and 289 healthy newborns (controls). Respiratory distress syndrome (OR 3.559, IC 1.865-6.794), low weight at birth (OR 3.504, IC 1.861-6.597) and prematurity (OR 5.044, IC 2.624-9.698) were significant, but not asphyxia. Other variables were similar in both mother groups.
  
  
  CONCLUSIONS
  Prenatal care produces low incidence of respiratory distress, low weight at birth and prematurity in the newborn. Neonatal mortality rate (6%), was lower than in other studies.
