Age-related deterioration in physical and oral health reduces healthy life expectancy and is thus an important problem for very elderly people. We investigated the effects of satisfaction with dietary life (SDL) in everyday life on oral health-related quality of life (OHRQoL) and subjective well-being and examined associations between these factors. We evaluated 426 elders aged 85 years or older. All participants completed a questionnaire that inquired about age, gender, drinking status, body mass index, cognitive function, disability, and comorbidities, among other covariates. Oral, physical, and mental health conditions were also examined. Associations of questionnaire results for SDL with items on subjective well-being (Philadelphia Geriatric Center Morale Scale [PGC] and World Health Organization-5 [WHO-5]) and OHRQoL (Geriatric Oral Health Assessment Index [GOHAI]) were confirmed with multiple logistic regression analysis. In a multivariate model adjusted for various confounders, participants with self-reported “enjoyable” SDL had significantly lower risks for having the lowest scores on the GOHAI, PGC, and WHO-5 (odds ratio [OR] = 0.460, 95% confidence interval [CI] = 0.277-0.762; OR = 0.589, 95% CI = 0.348-0.996; and OR = 0.452, 95% CI = 0.263-0.775, respectively). These associations remained after further adjustment for number of teeth.
