title: Birth weight, gestational age and medications during pregnancy.
abstract: OBJECTIVE
  To determine the effect of medication on birth weight and gestational age in 29,004 healthy newborn infants born to mothers with or without treatment of drugs.
  
  
  METHODS
  Birth weight and gestational age were evaluated in healthy control newborn infants in the population-based dataset of the Hungarian Case-Control Surveillance of Congenital Abnormalities (1980-1991) using multiple regression analysis.
  
  
  RESULTS
  Of 114 drugs used in more than 100 pregnant women, 19 had a positive or negative impact.
  
  
  CONCLUSIONS
  Further studies should be carried out to identify the possible mechanisms of medication and/or the maternal disorder for which this medication was given.
