Abstract

In the literature, most researchers evaluate individuals' nutritional status and chewing ability by types of foods chosen or blood test. However, most of previous researches enrolled small sample size and the results might be influenced by personal preference of foods as well as the individuals' response to invasive examination. In this study, researchers assessed individuals' nutritional status and chewing ability with non-invasive test and excluded the personal preference of foods. This study had two aims: first, to explore associations between chewing ability, edentulous or dentulous, self-perceived oral health and individuals' nutritional status and quality of life; second, to assess whether the association proposed by Locker's model is valid. This study used the database of Phase I 'Publicly-funded Denture Installation Plan for the Elderly' of Kaohsiung City Government. Nine hundred and fifty-four subjects aged 65 years and older completed the questionnaires for data analysis. The research results supported and verified the theoretical model proposed by Locker. Individual's chewing ability associated significantly with his/her nutritional status and quality of life. The results demonstrated that better chewing ability of the elderly leads to better nutritional status and quality of life. The appropriateness of the indicators and measurements of individual's chewing ability and nutritional status used in this study has been evaluated and presented. These indicators and measurements are suggested to be generally used for clinical or research application on future-related issues. Consequently, the maintenance or improvement in the chewing ability of the elderly is extremely beneficial to healthy ageing.
