Middle-aged and older adults are retaining teeth and avoiding dentures, which should impact quality of life. The aims of our study were to investigate tooth loss and chewing ability and their association with oral- and general-health-related quality of life and life satisfaction.
A random sample of 45- to 54-year-olds from Adelaide, South Australia, was surveyed by self-complete questionnaire in 2004-2005 (n = 879, response rate = 43.8%). Health-related quality of life was measured with the Oral Health Impact Profile 14-item version and EuroQol Visual Analogue Scale instruments and life satisfaction by the Satisfaction with Life Scale. Functional tooth units were recorded at oral examinations performed by calibrated dentists on 709 persons (completion rate = 80.7%).
Number of functional teeth was positively associated with chewing ability (beta = 0.31, P < 0.01). In multivariate analyses, controlling for number of functional teeth and other explanatory variables spanning dental visit pattern, dental behaviour, socio-demographics and socio-economic status, chewing ability was negatively associated with oral-health-related impacts (beta = -0.37, P < 0.01) and positively associated with general health (beta = 0.10, P < 0.05) and well-being (beta = 0.16, P < 0.01).
Chewing ability was related to oral-health-related quality of life and general health, possibly reflecting the impact of chewing on food choice and enjoyment of meals and diet, and also indicated the importance of oral health to general well-being.
中老年人保留牙齿并避免佩戴假牙，这会对生活质量产生影响。我们研究的目的是调查牙齿缺失和咀嚼能力，以及它们与口腔健康和总体健康相关的生活质量及生活满意度之间的关联。
2004年至2005年，通过自我填写问卷对来自南澳大利亚阿德莱德的45至54岁成年人进行随机抽样调查（n = 879，回复率 = 43.8%）。使用14项版本的口腔健康影响概况和欧洲生活质量视觉模拟量表工具测量与健康相关的生活质量，使用生活满意度量表测量生活满意度。由经过校准的牙医对709人进行口腔检查，记录功能性牙单位（完成率 = 80.7%）。
功能性牙齿数量与咀嚼能力呈正相关（β = 0.31，P < 0.01）。在多变量分析中，在控制功能性牙齿数量以及包括看牙模式、牙齿保健行为、社会人口统计学和社会经济地位等其他解释变量后，咀嚼能力与口腔健康相关影响呈负相关（β = -0.37，P < 0.01），与总体健康呈正相关（β = 0.10，P < 0.05），与幸福感呈正相关（β = 0.16，P < 0.01）。
咀嚼能力与口腔健康相关的生活质量和总体健康有关，这可能反映了咀嚼对食物选择、用餐享受和饮食的影响，也表明了口腔健康对总体幸福感的重要性。
