Oral health and cognitive status in the Concord Health and Ageing in Men Project: A cross-sectional study in community-dwelling older Australian men.

BACKGROUND: Several studies have examined the relationship between cognition and oral health in older populations. To further understand this relationship, we examined the associations between cognitive function, chewing capacity and the number of teeth present in community-dwelling older males in Australia. METHODS: Data were obtained from cross-sectional analysis of fourth wave of the Concord Health and Ageing in Men Project (CHAMP). Participants were 369 community-dwelling males aged 78 years or over. Cognitive function was measured utilising the Mini-Mental State Examination (MMSE). Chewing capacity was determined on ability to chew food items of different textures, and oral health data were collected. Ordinal regression was used to analyse associations between MMSE (four categories) and chewing capacity and number of natural teeth present. RESULTS: Overall, 67.5% of participants reported that they could chew all 11 listed food items. Participants with fewer than 20 teeth were statistically significantly more likely to have cognitive impairment (unadjusted odds ratio (OR) 1.87; 95% confidence interval (CI) 1.25-2.79, adjusted OR 1.62; 95% CI 1.07-2.43). Participants with limited chewing capacity were also more likely to have cognitive impairment (unadjusted OR 1.91; 95% CI 1.25-2.94, adjusted OR 1.61; 95% CI 1.03-2.49). CONCLUSIONS: This study suggests either that older men with fewer than 20 natural teeth and those with limited chewing capacity are more likely to have an associated cognitive impairment or that those with cognitive impairment are more likely to have fewer teeth and limited chewing capacity. Further longitudinal studies should clarify these relationships.

Associations between oral health and depressive symptoms: Findings from the Concord Health and Ageing in Men Project.

OBJECTIVE: To investigate whether poorer oral health, tooth loss and lower usage of dental services are associated with depressive symptoms in older Australian men. METHODS: Cross-sectional study of data collected from participants of the Concord Health and Ageing in Men Project. Depressive symptoms were evaluated by the Geriatric Depression Scale. Chewing capacity was estimated by ability to chew 11 food items. RESULTS: The prevalence of depressive symptoms was 17.5%. Self-evaluated oral health, chewing capacity and the number of natural and decayed teeth were associated with depressive symptoms. After adjusting for multiple confounders, chewing capacity (PR 1.93; 95% CI 1.34-2.79) and decayed teeth (PR 1.68; 95% CI 1.03-2.75) maintained a significant association with depressive symptoms. CONCLUSION: The direction of causality between oral health and depression is unclear; however, oral health may contribute to depression in older Australian men and depressive symptoms may limit chewing capacity and be aggravated by untreated dental decay.

The workforce outcomes of dental graduates from a metropolitan school 'Rural Clinical Placement Program' versus a 'Rural Clinical School'.

INTRODUCTION: This study compares the workplace decisions from University of Sydney (USYD) dental graduates who participated in a 1-month voluntary Rural Clinical Placement Program (RCPP), USYD graduates who did not participate in the RCPP (non-RCPP), and with graduates who qualified from a dental Rural Clinical School (RCS) at Charles Sturt University (CSU). METHODOLOGY: From mid-2015, USYD students who graduated between 2009 and 2013, and CSU graduates from 2013 to 2014, were requested to complete a telephone interview related to employment choices. For USYD, 135 interviews were completed (63% of contactable graduates) and for CSU, 39 interviews (68%). Mixed methods were applied to analyse the data. RESULTS: For USYD, 33% of RCPP participants were working rurally compared with 18% of the non-RCPP, whilst 54% of CSU graduates were working rurally. For USYD, the self-reported influence of the RCPP on the graduates' employment decisions was a significant predictor of rural employment. For CSU, country of birth and employment status were weakly associated with rural employment. Across the three cohorts, key employment factors were as follows: job availability, family, personal relationships, good mentorship, clinical training, partner factor and lifestyle. In addition, both the RCPP and CSU graduates showed greater interest and awareness of rural employment than the non-RCPP. CONCLUSION: The CSU RCS and USYD RCPP are leading to positive rural employment outcomes, and it is clear that the provision of a rural experience is influencing graduates to work rurally. Further investigation of the CSU program is required to fully assess its impact and to provide longitudinal workforce information.

Frailty and oral health: Findings from the Concord Health and Ageing in Men Project.

OBJECTIVE: To examine whether frailty in older men is associated with poorer oral health and lower levels of dental service utilisation. BACKGROUND: Poor oral health has been associated with some frailty components. Less is known about the link between frailty and oral health outcomes. METHODS: A cross-sectional analysis. Data were collected from 601 older men with both frailty status and oral health information. Frailty was defined as meeting three or more of the Cardiovascular Health Study criteria: weight loss, weakness, exhaustion, slowness and low activity. Dental service utilisation (DSU) behaviour was collected from self-response questionnaires and face-to-face interviews. Oral status (number of remaining and functional teeth, periodontal disease, active coronal decayed surface [ACDS] and self-rated oral health [SROH]) was recorded by two oral health therapists. The association between frailty and oral health behaviour and risk markers was modelled using logistic regression. RESULTS: Nineteen per cent of the participants were identified as frail. There were significant associations between frailty and dentition status (odds ratio [OR]: 2.49, 95% confidence interval [CI]: (1.17-5.30), and frailty and ACDS (OR: 3.01, CI: 1.50-6.08) but only ACDS remained significant after adjusting for confounders (adjusted OR: 2.46, CI: 1.17-5.18). There was no association between frailty and DSU and frailty and SROH. CONCLUSION: Frailty was independently associated with the presence of dental caries. However, DSU, SROH and other oral health markers were not significantly associated with frailty after adjusting for confounders. The prevalence of periodontal disease was high regardless of their frailty status.
