title: [The prevalence of exposure of children under the age of 18 to second-hand smoke inside motor vehicles].
abstract: BACKGROUND
  The objective of the study was to estimate the level of exposure of children under the age of 18 to second-hand smoke (SHS) inside motor vehicles.
  
  
  METHODS
  A prevalence study was conducted on the exposure of children under the age of 18 to SHS in motor vehicles in Lleida (Spain). The population was the users of private motor vehicles. The sample was random, and the data were collected by direct observation. The study variables were: the age and sex of the driver, whether the driver was smoking, and the presence of an exposed passenger under the age of 18.
  
  
  RESULTS
  A total of 1600 vehicles were observed, 134 of which (8.4%) were carrying a child. In 8 of these 134 vehicles (6%; 95% CI: 2.5-11.0) a child was exposed to SHS. In all these cases, the driver was a male (P=0.02), and in 75% of cases he was over 40 years old.
  
  
  CONCLUSIONS
  The rate of child exposure to SHS is very high. There is, therefore, a case for organising campaigns to prevent smoking tobacco inside motor vehicles in the presence of children in Spain.
