Satisfaction with dietary life affects oral health-related quality of life and subjective well-being in very elderly people.

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.

Perceived swallowing problems and mortality risk in very elderly people ≥85 years old: Results of the Tokyo Oldest Old Survey on Total Health study.

Objective: The aim of this study was to clarify whether perceived swallowing problems affect the life expectancy of very elderly individuals.

Background: In an ageing society, oral function affects health status. In particular, a decline in swallowing function may increase the risk of various diseases, morbidity and malnutrition.

Maximum occlusal force and physical performance in the oldest old: the Tokyo oldest old survey on total health.

Objectives: To elucidate the independent relationship between masticatory and physical performance in community-living oldest old people (mean age ± standard deviation 87.8 ± 2.2, range 85-102).
