Assessing a conceptual model with both oral health and health related quality of life in community-dwelling elders.
Archives of gerontology and geriatrics(2018)
摘要
PURPOSE:The objective of this study was to test a hypothesized conceptual model for both the clinical and non-clinical status of oral health and health related quality of life (OHRQoL & HRQoL) among community-dwelling elders.
MATERIALS AND METHODS:Study participants (n = 517), who were recruited as part of a Taiwanese elderly community survey, were collected via dental examinations and questionnaires. We collected measures of clinical variables, self-reported symptom status, OHRQoL, nutritional status and HRQoL. The 517 participants were randomly assigned to one of two samples, to provide one training sample for estimation and one testing sample for validation. The path analysis with all observed variables was conducted based on the proposed theoretical model delineating pathways.
RESULTS:All of the direct pathways hypothesized by the model were significant. Functional status (OHRQoL measured by OHIP-14T) mediated clinical occlusion, and symptom status mediated nutritional status (MNA) and HRQoL (WHOQOL-BREF). The model accounted for 29% of the variance in HRQoL and demonstrated a good fit with the data.
CONCLUSIONS:This conceptual model suggests that OHRQoL, as an important mediator, links clinical conditions, symptom status, nutritional status, and overall HRQoL. Therefore, when therapeutic efforts are made to improve the outcomes for patients with oral diseases, not only can the OHRQoL be enhanced, but also the HRQoL can be improved as a result.
