Aim: To obtain information about the impact of oral health status on the quality of life in older adults in Central China, and furthermore, to investigate the influence of various demographic and socio-economic factors on oral health related quality of life (OHRQoL). Methods: This study comprised a stratified random sample of 1,000 older adults in Central China. Questionnaires including demographic factors, education and income level, denture wearing status and Oral Health Impact Profile (OHIP)-14 were used in a face-to-face interview. Results: Of the study population 82% stated that they had some forms of problems related to their quality of life. The mean value of the simple count and single summary item scores for OHIP-14 were 0.47 (sd 0.50) and 6.83 (sd 6.84) respectively for the entire study population. “Uncomfortable to eat” and “taste worse” were the two most common problems reported using the simple count method for OHIP-14, while the “physical pain” being the highest scored domain of the measure. When the effect of all independent variables was analysed in multivariate analysis, education level and denture wearing status were significantly (p<0.05) associated with the OHRQoL measure. Conclusions: In this Chinese older adult sample, education level and denture wearing status were related to having oral problems as estimated using the OHIP-14. Key words: oral health impact profile (OHIP)-14, oral health related quality of life (OHRQoL)
