Self-perception of oral health in the elderly associated with health literacy and related factors


 The aim of this study was to evaluate the self-perception of oral health in the elderly and to verify its association with oral health literacy and sociodemographic factors, through a cross-sectional study. Data collection took place in a probabilistic sample consisting of 535 elderly people over 60 years of age, who did not have cognitive problems, and were residents of the areas covered by six Family Health Units of the public health service, as well as users of a Center for Dental Specialties and dental clinics at the Faculty of Dentistry of Piracicaba (FOP), all located in the city of Piracicaba, Sao Paulo. A questionnaire with sociodemographic and health issues was applied, as well as the Health Literacy in Dentistry (HeLD-14) instrument for the assessment of oral health literacy. Poisson regression was used to estimate the associations between self-perceived oral health and literacy in oral health, as well as sociodemographic and general health characteristics. The data were analyzed using the SAS statistical software. The final regression model demonstrated that the elderly who were more likely to report poor oral health self-perception were associated with a low level of oral health literacy, were of the “non-white” ethnic group, had chronic illnesses and had sought the dentist for curative reasons in the last year. It was concluded that the self-perception of oral health in the elderly is influenced by variables that go beyond the dental sector, a fact that demands multiprofessional and intersectoral actions for their care. This fact highlights the importance of integrating aspects of health literacy in health and sociodemographic factors into the process of assessing oral health in the elderly, expanding the perspective of public health assessment for actions focused only on normative needs.
 
 
 We show the importance of assessing the oral health of the elderly in association with health literacy, expanding the perspective of public health assessment to actions beyond the normative needs. Despite the importance of the topic, there is still a scarcity of studies on health literacy and its impact on oral health behaviors and outcomes, impacting public health.
