title: Pregnancy complications associated with hepatitis C: data from a 2003-2005 Washington state birth cohort.
abstract: OBJECTIVE
  The objective of the study was to determine the effect of hepatitis C virus (HCV) on selected maternal and infant birth outcomes.
  
  
  METHODS
  This population-based cohort study using Washington state birth records from 2003 to 2005 compared a cohort of pregnant women identified as HCV positive from birth certificate data (n = 506) to randomly selected HCV-negative mothers (n = 2022) and drug-using HCV-negative mothers (n = 1439).
  
  
  RESULTS
  Infants of HCV-positive mothers were more likely to be low birthweight (odds ratio [OR], 2.17; 95% confidence interval [CI] 1.24, 3.80), to be small for gestational age (OR, 1.46; 95% CI, 1.00, 2.13), to need assisted ventilation (OR, 2.37; 95% CI, 1.46, 3.85), and to require neonatal intensive car unit (NICU) admission (OR, 2.91; 95% CI, 1.86, 4.55). HCV-positive mothers with excess weight gain also had a greater risk of gestational diabetes (OR, 2.51; 95% CI, 1.04, 6.03). Compared with the drug-using cohort, NICU admission and the need for assisted ventilation remained associated with HCV.
  
  
  CONCLUSIONS
  HCV-positive pregnant women appear to be at risk for adverse neonatal and maternal outcomes.
