title: Low birth weight, preterm birth and short interpregnancy interval in Sudan.
abstract: OBJECTIVE
  To investigate whether short interpregnancy interval (IPI) is associated with increased risk of low birth weight and preterm labour.
  
  
  METHODS
  The study was conducted in the labour ward of Khartoum hospital in Sudan during November 2007 through February 2008. Odds ratios (ORs) were adjusted for the confounding factors using multiple logistic regression models.
  
  
  RESULTS
  Compared with IPI of 18-30 months, those women with intervals shorter than 18 months had an increased risk of low birth weight (OR = 1.9, 95% CI = 1.0-3.5, P = 0.04) and preterm labour (OR = 2.3, 95% CI = 1.1-4.7, P = 0.01).
  
  
  CONCLUSIONS
  In this study, IPI shorter than 18 months are independently associated with increased risk of adverse perinatal outcomes.
