title: Factors associated with self-reported use of mouthwashes in southern Brazil in 1996 and 2009.
abstract: OBJECTIVE
  To evaluate the association between sociodemographic factors and self-reported use of mouthwashes in a city in the south of Brazil over a time span of 13 years.
  
  
  METHODS
  The study involves a comparison of two household surveys conducted in 1996 and 2009. Respectively, 850 and 982 households were included in each year. The mother of the family answered to a structured questionnaire to provide sociodemographic data. Self-reported use of mouthwash was evaluated in a binary manner (yes/no). Multivariate Poisson regression models were used to estimate proportion ratios (PR) and 95% confidence intervals (95% CI).
  
  
  RESULTS
  The proportion of mouthwash use increased significantly from 10.8% to 24.2% after 13 years. The probability of using mouthwashes increased more than two times from 1996 to 2009 (PR = 2.25 95% CI 1.80-2.82). Higher probabilities for using mouthwashes were observed in households with higher income (PR = 2.63 95% CI 1.97-3.51) and in those households where the mothers had higher educational levels (PR = 1.46 95% CI 1.05-2.03).
  
  
  CONCLUSIONS
  Higher family income and higher maternal educational level were associated with self-reported use of mouthwashes in a higher proportion of households.
