title: [Estimation of environmental tobacco smoke exposure: review of questionnaires used in Spain].
abstract: BACKGROUND
  In the last few years, health surveys and epidemiological studies on smoking have introduced questions on environmental tobacco smoke (ETS) exposure. However, a standardized questionnaire is lacking.
  
  
  METHODS
  Between January and May 2008, we reviewed surveys containing items on ETS exposure carried out in Spain by public administrations, scientific societies and research institutes. The wording of the questions was reviewed and classified according to the study type, target population, geographical setting and place of exposure.
  
  
  RESULTS
  We identified 27 surveys that included questions on passive smoking. Most were health surveys (81.5%) and were aimed at the general population (70.4%). The most frequent geographical setting consisted of autonomous regions (48.1%) and the most common place of exposure was the home (88.9%)
  
  
  CONCLUSIONS
  The results show wide variability in the questions used. Questionnaire items on ETS exposure should be homogenized to allow comparison of the results of surveys.
