BACKGROUND/PURPOSE: Improvement of the medical and social environment is an important aspect of government policies in assuring the quality of life (QoL) of older adults. However, few studies have appraised the impact and relationship of QoL with clinical factors among elderly individuals in affluent residential areas.
A total of 166 older adults from Chang Gung Health and Culture Village were enrolled. Oral health-related QoL was measured using the Geriatric Oral Health Assessment Index. Self-assessed chewing abilities and demographic characteristics were collected by questionnaire. Physical health was scored by activities of daily living (ADL) and instrumental ADL. Mini nutrition assessment questionnaire was used to evaluate the nutritional intake. Multiple linear regression was used to predict risk factors affecting QoL and to examine whether chewing ability was a mediator of oral health-related QoL.
Poor chewing ability was associated with older age (OR = 1.82 for 76-85 years and 3.58 for 86-95 years), sufficient economic status (OR = 5.55) and removable denture-wearing (OR = 7.52). On the other hand, poor chewing ability (OR = 0.11), removable denture-wearing (OR = 0.48), periodontal disease (OR = 0.38) had lower likelihood of good oral health-related QoL. Mediator analyses showed that chewing ability was a mediator for the association between oral health-related QoL and economic status or removable denture-wearing or having more than 20 teeth. Periodontal disease was an independent factor for oral health-related QoL.
Among older adults in an affluent community, periodontal disease is an independent risk factor directly related to oral health-related QoL, whereas chewing ability is a mediator between QoL and removable denture-wearing.
背景/目的：改善医疗和社会环境是政府确保老年人生活质量（QoL）政策的一个重要方面。然而，很少有研究评估 QoL 对富裕居住地区老年人群的影响及其与临床因素之间的关系。
共纳入来自长庚健康文化村的 166 名老年人。使用老年口腔健康评估指数（Geriatric Oral Health Assessment Index）评估口腔健康相关 QoL。通过问卷收集自我评估的咀嚼能力和人口统计学特征。日常生活活动（ADL）和工具性日常生活活动（IADL）评分评估身体健康。微型营养评估问卷用于评估营养摄入。采用多元线性回归预测影响 QoL 的危险因素，并检验咀嚼能力是否为口腔健康相关 QoL 的中介因素。
咀嚼能力差与年龄较大（76-85 岁时 OR=1.82，86-95 岁时 OR=3.58）、经济状况较好（OR=5.55）和佩戴可摘义齿（OR=7.52）有关。另一方面，咀嚼能力差（OR=0.11）、佩戴可摘义齿（OR=0.48）、牙周病（OR=0.38）的人，口腔健康相关 QoL 较好的可能性较低。中介分析表明，咀嚼能力是口腔健康相关 QoL 与经济状况或佩戴可摘义齿或拥有 20 多颗牙齿之间关系的中介因素。牙周病是口腔健康相关 QoL 的独立因素。
在富裕社区的老年人中，牙周病是直接影响口腔健康相关 QoL 的独立危险因素，而咀嚼能力是 QoL 与佩戴可摘义齿之间的中介因素。
