[Prevalence of poor self-rated mastication and associated factors in Brazilian elderly]. / Prevalência de capacidade mastigatória insatisfatória e fatores associados em idosos brasileiros.

We estimated the prevalence of poor self-rated mastication and associated factors among Brazilian elders. The study used data from a national survey of 5,124 Brazilian elderly in 250 cities. Data collection included dental examinations and household interviews with the elderly. The outcome was self-rated mastication. Data analyses used Poisson regression, and the prevalence of poor self-rated mastication was 49.7% (95%CI: 47.5-51.8). Adjusted analyses showed that increased prevalence was associated with: black color/race (PR = 1.13; 95%CI: 1.02-1.26); low income (PR = 1.22; 95%CI: 1.12-1.33.); high rates of tooth loss (PR = 1.66; 95%CI: 1.02-2.66); untreated caries (PR = 1.16; 95%CI: 1.08-1.25); never having visited a dentist (PR = 1.26; 95%CI: 1.10-1.44); toothache (PR = 1.47; 95%CI: 1.39-1.57); use of partial (PR = 0.87; 95%CI: 0.76-0.99) or total prostheses (PR = 0.81; 95%CI: 0.75-0.88); and need for partial (PR = 1.13; 95%CI: 1.03-1.25) or total prostheses (PR = 1.27; 95%CI: 1.16-1.39). The high prevalence emphasizes the dental care needs of this older group. Policies to deal with the problem should take the associated factors into account.

Prevalência de capacidade mastigatória insatisfatória e fatores associados em idosos brasileiros / Prevalence of poor self-rated mastication and associated factors in Brazilian elderly

Estimou-se a prevalência de capacidade mastigatória insatisfatória referida e fatores associados entre a população de 65 a 74 anos no Brasil. Este estudo faz parte da pesquisa Condições de Saúde Bucal da População Brasileira com 5.124 idosos de 250 municípios. Os dados foram coletados nos domicílios incluindo exame dentário e entrevista. A análise utilizou regressão de Poisson, 2.546 pessoas (49,7 por cento; IC95 por cento: 47,5-51,8) referiram capacidade mastigatória insatisfatória. Na análise ajustada, estavam associadas as variáveis: cor da pele negra (RP = 1,13; IC95 por cento: 1,02-1,26); baixa renda (RP = 1,22; IC95 por cento: 1,12-1,33.); ter dor de dente nos últimos meses (RP = 1,47; IC95 por cento: 1,39-1,57), nunca ir ao dentista (RP = 1,26; IC95 por cento: 1,10-1,44), não receber orientações preventivas (RP = 1,09; IC95 por cento: 1,02-1,17) ter dentes perdidos (RP = 1,66; IC95 por cento: 1,02-2,66), cáries não tratadas (RP = 1,16; IC95 por cento: 1,08-1,25), usar prótese parcial (RP = 0,87; IC95 por cento: 0,76-0,99) ou total (RP = 0,81; IC95 por cento: 0,75-0,88) e necessitar prótese dentária parcial (RP = 1,13; IC95 por cento: 1,03-1,25) ou total (RP = 1,27; IC95 por cento: 1,16-1,39). Assim, aponta para a priorização dos idosos levando-se em consideração seus fatores associados.
