The relationship between oral-health-related quality of life and general health in an elderly population: a cross sectional study

Objective: To assess the oral‐health‐related quality of life (OHRQoL) in a cohort of Irish older patients and explore associations with overall health status.Background: The impact of oral health conditions on older individuals’ quality of life may be influenced by patients’ general health status. Background: The impact of oral health conditions on older individuals’ quality of life may be influenced by patients’ general health status.Materials and Methods: This paper reports a cross‐sectional study, which analysed baseline data from patients aged over 60 years. Patients were recruited from two different environments, namely Cork University Dental Hospital and St. Finbarr’s Hospital, to take part in two research studies. All patients completed the Oral Health Impact Profile (OHIP‐14) and EuroQol‐5D (EQ‐5D) questionnaires. All patients pro‐vided a comprehensive overview of their general medical status. Data from the Quality of Life questionnaires were analysed to check for differences between healthy and frail elders and explore associations between OHRQoL and general health. Results: The patient sample comprised 146 (44.6%) male and 181 (55.4%) female participants, with a mean (SD) age of 73.96 (6.9). Frail patients reported a higher mean OHIP‐14 score compared to non‐frail patients (P < 0.001). Pearson’s correla‐tion analysis showed a negative association between OHIP‐14 and EQ‐5D scores. Regression analysis showed that among frail individuals, better general health cor‐responded to poorer OHRQoL. In the non‐frail cohort, better general health was re‐lated to better OHRQoL, although these results were not statistically significant.Conclusions: General health was not significantly associated with the way that pa‐tients perceive their oral health within this patient cohort. However, factors such as objective oral health, denture wear and patient’s expectations may play a role in this association.
