title: Is there an increased lability in parents' smoking behaviour after a childbirth?
abstract: OBJECTIVE
  To test our hypothesis that there is an increased lability in parents' smoking behaviour after a childbirth, and to search for demographic factors associated with lability in parents' smoking behaviour.
  
  
  METHODS
  A one month, prospective questionnaire study.
  
  
  METHODS
  Maternal and child health centres in Oslo, Norway.
  
  
  METHODS
  222 families in which at least one adult was smoking were enrolled in the study. 37 families dropped out (16.7%) and 185 families completed both questionnaires.
  
  
  METHODS
  Changes in daily smoking, smoking quantity, and practical measures to prevent passive smoking by the children, as assessed by parental reports.
  
  
  RESULTS
  Families with a child aged less than one year (infant) were more likely to make one or another positive change (quit, reduce, stop smoking indoors, stop smoking in living rooms) than families with only older children. There was a trend for families with an infant to make negative changes more often (start smoking, increase) as well. Older parents made positive changes more often than younger ones. Single parents were less likely to make positive changes.
  
  
  CONCLUSIONS
  The study indicates that there is an increased lability in parents' smoking behaviour after a childbirth.
