title: A survey on prenatal environmental risk factors for mothers of low birth weight infants in asan-city.
abstract: OBJECTIVE
  In this study, we aimed to produce basic data on the prenatal environmental risk factors of low birth weight infants at a community level.
  
  
  METHODS
  In 2000, we conducted the direct interview using questionnaire about prenatal environmental risk factors with low birth weight infant-delivered mothers and normal weight infant-delivered mothers in Asan-city, Chungcheongnamdo Province, Korea. The questions given to the mothers included past pregnancy history, menstrual status, disease history before and during the pregnancy, family history, environmental risk factors and exposure history. The responses of the two groups were compared to calculate the prenatal environmental risk factors of each group.
  
  
  RESULTS
  Mothers' smoking was significantly associated with low birth weight infants (adjusted odds ratio (AOR) 3.27; 95% confidence interval (CI) 1.25-8.56) and preterm baby (AOR 4.20; 95% CI, 1.21-14.61). Other environmental risk factors were not significantly different between the two groups.
  
  
  CONCLUSIONS
  Smoking of mothers can be a risk factor for the delivery of low birth weight infants. These results could provide the basic data on prenatal environmental risk factors of mothers of low birth weight infants and suggest research topics for further community-based evaluation.
