Abstract

AbstractStudies assessing edentulism in a population-base sample are scarce. To evaluate the prevalence of edentulism and associated factors among older adults. A cross-sectional home-based observational study with a probabilistic sample per cluster was conducted with 282 older adults aged ≥60 years in the city of Veranópolis/Brazil. Clinical oral health examination and a structured questionnaire was administered. The main outcome was edentulism. Uni- and multivariate analyses were performed, using Poisson regression with robust variance. The prevalence of edentulism was 48.6% (n=137). In the final multivariate model, age, level of education and access to the dentist remained associated with edentulism. With each one-year increase in age, there is a 2.7% increase in the Prevalence Ratio (PR) of being edentulous (PR: 1.027; 95% confidence interval [95%CI]:1.015–1.039). Older adults with medium/high level of education had 39.4% lower PR of being edentulous (PR: 0.606; 95%CI:0.382–0.961). Older adults without access to the dentist had 78% (p<0.001) higher PR of being edentulous when compared to those that visited the dentist in the last 12 months. The prevalence of edentulism in the older adults was high and was associated with sociodemographic and access to oral care variables. Keywords: Aged. Tooth Loss. Risk Factors. Epidemiology. ResumoEstudo que avaliem edentulismo em uma amostra de base populacional são escassos. Avaliar a prevalência de edentulismo e fatores associados em idosos. Um estudo transversal de base populacional com amostra probabilística per cluster foi conduzida com 282 idosos, com idade ≥60 anos, na cidade de Veranópolis/Brasil. Exames orais e questionário estruturados foram realizados. O principal desfecho foi edentulismo. Análise uni- e multivariada foram realizadas, utilizando regressão de Poisson com variância robusta. A prevalência de edentulismo foi 48,6% (n=137). No modelo multivariado final, idade, nível educacional e acesso ao dentista permaneceram associados com edentulismo. Para cada ano de aumento, há um aumento da razão de prevalência (RP) de 2,7% em ser edêntulos (RP: 1,027; intervalo de confiança de 95% [IC95%]: 1,015–1,039). Idosos com nível educacional médio/alto apresentaram 39,4% menor RP de ser edêntulos (RP: 0,606; IC95%: 0,382–0,961). Idosos sem acesso ao dentista presentaram 78% (p<0,001) maior RP de ser edêntulos quando comparado com aqueles que visitaram o dentista nos últimos 12 meses. A prevalência de edentulismo nos idosos foi alta e esteve associado com variáveis sociodemográficos e acesso ao dentista. Palavras-chave: Idoso. Perda de Dente. Fatores de Risco. Epidemiologia.
