title: [Is low pre-pregnancy body mass index a risk factor for preterm birth and low neonatal birth weight?].
abstract: OBJECTIVE
  A pregnant woman's weight is an extremely important factor in the course of pregnancy and delivery. Not only obesity but also being underweight may lead to complications in pregnancy such as: preterm delivery and low neonatal birth weight.
  
  
  METHODS
  The aim of this study was to analyze the relationship between a low BMI and outcome of pregnancy, birth weight and general well being of the neonates.
  
  
  METHODS
  415 patients who were hospitalized in the Department of Obstetrics and Reproduction Wrocław Medical University between 1996-2005 was done. The patients were divided into 3 groups I--Underweight (BMI <19,8), II--Appropriate weight (BMI 19,8-26,0) and III--Overweight (BMI>26,0).
  
  
  RESULTS
  The frequency of preterm deliveries as well as low neonatal birth weight <2500g, in underweight mothers was higher than in other groups.
  
  
  CONCLUSIONS
  Low pre-pregnancy BMI is an important factor risk factor in preterm deliveries. There was no correlation between BMI and the general well being of the neonates.
