Topic: Risk, prevention and care in population studies
Aim The aim of this study was to assess chewing ability using color-changeable chewing gum and to show the association between chewing ability and geriatric functions, as well as dietary status in the community-dwelling elderly.

Key findings
- Methods The study population consisted of 269 community-dwelling elderly aged ≥ 75 living in Tosa, Japan.
- Assessment of chewing ability was carried out by a dentist using color-changeable chewing gum.
- Activities of daily living (ADL), depression and subjective quality of life (QOL) were assessed by questionnaire.
- Cognitive status was assessed by; Mini-Mental State Examination (MMSE), Hasegawa Dementia Scale-Revised (HDS-R) and Frontal Assessment Battery (FAB) during the check-up.
Why it matters
This study assessed chewing ability in community-dwelling elderly people and its association with daily activities, depression, cognitive status and food intake. It is about general geriatric function, not about treating, curing or preventing Alzheimer's disease.
