title: Environmental tobacco smoke in Norwegian homes, 1995 and 2001: changes in children's exposure and parents attitudes and health risk awareness.
abstract: BACKGROUND
  The aims of the present study were to assess changes between 1995 and 2001 in the prevalence of child exposure to environmental tobacco smoke (ETS), attitudes towards ETS among parents of small children and awareness among parents regarding the potential hazards of passive smoking to children.
  
  
  METHODS
  A questionnaire, along with a stamped, addressed envelope, was sent to a stratified random sample of 1000 households in Norway containing children aged 3 years old at the time of the investigation (May 1995 and August 2001).
  
  
  RESULTS
  The prevalence of households containing smokers was similar in the two study periods. However, households reporting exposure of children to ETS fell from 32% in 1995 to 18% in 2001. Health-risk awareness had significantly increased in households containing smokers. In both surveys, the probability of children being exposed to ETS was positively correlated with the number of parents smoking, and inversely correlated to strength of health-risk awareness, negative attitudes towards ETS and length of household education.
  
  
  CONCLUSIONS
  Increasing parents' awareness of the health risk of ETS exposure to children may significantly reduce children's ETS exposure.
