title: Physical abuse during pregnancy and risk of low-birthweight infants among aborigines in Taiwan.
abstract: OBJECTIVE
  The aim of this study was to assess whether physical abuse during pregnancy is associated with an increased risk of giving birth to a low-birthweight (LBW) infant.
  
  
  METHODS
  A cross-sectional survey was conducted and 1143 aboriginal women were recruited into this study. The Abuse Assessment Screen was used to collect information regarding maternal physical abuse, and infants' birth weights were obtained from hospital medical records. Multiple logistic regression was used to estimate the association of LBW with physical abuse during pregnancy, adjusting for behavioural and sociodemographic variables.
  
  
  RESULTS
  Of the women experiencing physical abuse during their recent pregnancy, 11.76% delivered a LBW infant, compared with 5.78% of women who did not experience physical abuse [odds ratio (OR) 1.97, 95% confidence intervals (CI) 1.07-3.63]. Physical abuse during pregnancy was also significantly associated with low weight gain in the prenatal period. Univariate analysis revealed that delivery of a LBW infant was associated with maternal alcohol use, maternal betel chewing and maternal educational level. Multiple logistic regression was performed, adjusting for prenatal weight gain, maternal height, maternal years of education, maternal alcohol use and maternal betel quid use. It was found that women who reported physical abuse with injuries during pregnancy had a 2.4-fold higher risk of delivering a LBW infant compared with women who did not report physical abuse with injuries (adjusted OR=2.43, 95%CI 1.06-5.55).
  
  
  CONCLUSIONS
  These findings suggest that physical abuse during pregnancy is an independent risk factor for delivery of a LBW infant. Prenatal care for aboriginal women should be coupled with routine systematic screening for the presence of abuse during pregnancy, and adequate support and interventions for abused women.
