title: [Tobacco use in Mexican households: results of the Income and Expenses Survey of Households, 1984-2000].
abstract: OBJECTIVE
  To analyze selected determinants of tobacco consumption in Mexican homes.
  
  
  METHODS
  Data from the National Household Income and Expenditure Survey, 1984-2000, were analyzed. The analysis was conducted for the years 1984-1992 and 1994-2000. The likelihood of tobacco consumption in households was estimated with a logistic regression model.
  
  
  RESULTS
  Tobacco consumption during the first period was two times more likely from decile six (OR = 2.03, 95%, CI: 2.03-2.04) and during the second period from decile eight (OR = 2.06, 95%, CI: 2.05-2.07). Households from decile one spent on average 9-22% of their income on tobacco; almost all of the households from decile ten spent only 1% of their income on tobacco.
  
  
  CONCLUSIONS
  Households with higher income consumed more tobacco than households with low income; nevertheless, households with the lowest income devoted a greater proportion of income to tobacco consumption.
