title: Secondhand smoke in New Zealand homes and cars: exposure, attitudes, and behaviours in 2004.
abstract: OBJECTIVE
  To assess exposure to secondhand smoke (SHS) in New Zealand homes and cars and to describe attitudes and behaviours that relate to establishing smokefree settings.
  
  
  METHODS
  In 2004, a nationwide telephone survey randomly selected and interviewed 2731 respondents. This sample was weighted to represent the national population and was comprised of a general adult population sample (n=1507), a sample selected from the Maori electoral roll (n=924), and a sample of current smokers and people who had recently quit smoking (n=300).
  
  
  RESULTS
  19.6% of the general population and 42.7% of the Maori sample reported current smoking. Of all current smokers, 47.2% smoked indoors at home and 70.8% smoked in their cars. Maori participants were significantly more likely to be exposed to SHS in their homes than non-Maori participants. There was also some evidence for lower socioeconomic status being related to higher SHS exposure. Extrapolating from the adult exposure data in households with children, it was estimated that 18.9% of children were potentially exposed to SHS indoors at home. However, most respondents (73.6%) lived in homes with total smoking bans.
  
  
  CONCLUSIONS
  SHS exposure remains a significant problem especially for Maori and low-income New Zealanders. There is a need for further public health campaigns to increase the prevalence of smokefree homes and cars.
