OBJECTIVE The aim of this study was to investigate the relationships between the oral and nutritional status of older residents with dementia in an aged care nursing home. BACKGROUND Insufficient oral evaluation and care due to refusal of treatment in older people with dementia may cause deterioration in oral and nutritional status. MATERIALS AND METHODS The subjects were 123 older residents with dementia who had been admitted to an aged care nursing home. Oral condition and body mass index (BMI) as a measure of nutritional status were investigated, and the results for the mild and severe dementia groups were compared. BMI was compared by the food consistency between the mild and severe dementia groups. RESULTS In the severe dementia group, fewer older adults had removable dentures and many had no molar occlusion. The rate of subjects who had refused oral care by the caregivers was significantly higher in the severe dementia group than in the mild dementia group. In the severe dementia group, the BMI of those having texture-modified foods was significantly lower than those having a normal diet. The BMI of subjects without molar occlusion and with a history of cerebrovascular disease was significantly lower in the severe dementia group. CONCLUSIONS The BMI of subjects in the severe dementia group having texture-modified food was significantly lower than that of those with a normal diet. The BMI of subjects in the severe dementia group without molar occlusion was significantly lower than those with molar occlusion.
