|概要||Previous studies have examined the relationship between cognition and oral health among older populations. To further understand these relationships, this study examined the associations between cognitive function, chewing capacity and the number of natural teeth present in community dwelling older males in Australia.
Data were obtained from cross-sectional analysis of the 4th wave of The Concord Health and Ageing in Men Project (CHAMP). 369 community dwelling males aged 78 years or over participated in the study. Cognitive function was measured by utilizing Mini-Mental State Examination (MMSE). Chewing capacity was determined by a nutritionist administered survey of participants capacity to chew 11 food items, and oral health data were collected by calibrated dental professionals. 17 participants (4.6%) had cognitive impairment (MMSE score < 24). Ordinal regression analysis adjusting for confounders showed participants with fewer than 20 natural teeth (OR = 1.62; 95% CI 1.07- 2.43) and with limited chewing capacity (OR = 1.61; 95% CI 1.03- 2.49) were more likely to be cognitively impaired. Further research is required to elaborate the causative pathways of these associations.
The study suggests that older men with fewer natural teeth and those with limited chewing capacity are at a higher risk of cognitive impairment.
