Aims:To investigate the factors associated with poor oral health-related quality of life (OHRQoL) in a sample of Brazilian older adults. Methods and Results: A cross-sectional study was conducted with 535 noninstitutionalized elders aged 60 years or older from Piracicaba, São Paulo, Brazil. OHRQoL was measured using the Geriatric Oral Health Assessment Index (GOHAI). Data on sociodemographic characteristics, self-perceived general health status, and health-related behaviors were obtained through a structured questionnaire. Data on chronic diseases were obtained from health records. Associations between exploratory factors and low OHRQoL (% GOHAI score <30) were evaluated using multivariate Poisson regression models to estimate adjusted prevalence ratios (PRs) and confidence intervals. The mean OHRQoL score was 30 (± 4.4). In bivariate analysis, being not married, smoking, and selfrated "fair/poor" general health status were associated with lower OHRQoL. In the adjusted model, self-rated "fair/poor" general health (PR: 1.25; 95% CI: 1.05-1.48), presence of chronic diseases (PR: 1.88; 95% CI: 1.37-2.58), smoking (PR: 1.25; 95% CI: 1.02-1.53), and reason for last dental appointment (PR: 1.34; 95% CI: 1.13-1.59) were associated with poor OHRQoL. Conclusion: Non-institutionalized older adults with a history of chronic diseases, who smoke, have a negative perception of their general health, and had the last dental appointment motivated by pain present significantly higher prevalence rates of poor OHRQoL.

INTRODUCTIONIt is estimated that the number of people aged 60 years or older at a global level will exceed 2 billion by the year © 2021 Special Care Dentistry Association and Wiley Periodicals LLC 2050, representing one fifth of the world population. By then, approximately 80% of the older population will live in developing countries. 1 In Brazil, a rapid demographic transition characterized by increasing life expectancy and
