Physical ability and comorbidity and oral health among home-dwelling older people in the Finnish population.

AIM

To examine how physical ability and comorbidity associate with oral health.

METHODS AND RESULTS

The study population comprised 161 individuals belonging to the Oral Health GeMS study. Outcome variables were the number of teeth with dental caries and deepened periodontal pockets and self-perceived oral health (pain/discomfort in mouth). Physical ability was determined by measuring limitations in daily activities (activities of daily living [ADL] and instrumental activities of daily life [IADL]) and the number of comorbidities with Functional Comorbidity Index (FCI). Poisson's multivariate regression model was used to estimate prevalence rate ratio (PRR) and their 95% confidence intervals (CI). The physical ability or number of comorbidities did not associate consistently with oral diseases, but ADL, IADL and FCI associated all with self-perceived oral discomfort (PRR: 1.74, CI: 1.01-3.03; PRR: 1.20, CI: 1.06-1.35; PRR: 1.20, CI: 1.05-1.36, respectively). Furthermore, IADL associated also with poor self-perceived oral health (PRR: 1.27, CI: 1.03-1.57).

CONCLUSION

Older people with impaired physical ability and comorbidities are more likely to have oral discomfort and have poorer self-perceived oral health.
