title: Self-rated oral health and associated factors in Brazilian elders.
abstract: OBJECTIVE
  Self-rating provides a simple direct way of capturing perceptions of health. The objective of this study was to estimate the prevalence and associated factors of poor self-rated oral health among elders.
  
  
  METHODS
  National data from a cross-sectional population-based study with a multistage random sample of 4786 Brazilian older adults (aged 65-74) in 250 towns were analysed. Data collection included oral examinations (WHO 1997) and structured interviews at elderly households. The outcome was measured by a single five-point-response-scale question dichotomized into 'poor' (fair/poor/very poor) and 'good' (good/very good) self-rated oral health. Data analyses used Poisson regression models stratified by sex.
  
  
  RESULTS
  The prevalence of poor self-rated oral health was 46.6% (95% CI: 45.2-48%) in the whole sample, 50.3% (48-52.5) in men and 44.2% (42.4-46) in women. Higher prevalence ratios (PR) were found in elders reporting unfavourable dental appearance (PR = 2.31; 95% CI: 2.02-2.65), poor chewing ability (PR = 1.64; CI: 1.48-1.8) and dental pain (PR = 1.44; CI: 1.04-1.23) in adjusted analysis. Poor self-perception was also associated with being men, black, unfavourable socioeconomic circumstances, unfavourable clinical oral health and with not using or needing a dental prosthesis.
  
  
  CONCLUSIONS
  Assessment and understanding of self-rated oral health should take into account social factors, subjective and clinical oral symptoms.
