目的确定在一般老年人群中牙齿脱落、咀嚼能力和认知功能之间是否存在关联。对2002年全国高龄老人生活条件跟踪调查的设计数据进行了分析。采用逐步logistic回归分析研究认知功能与牙齿脱落和咀嚼能力之间的关系。557人是瑞典77岁及以上人口的全国代表。认知功能的测量使用简易精神状态检查的简化版本。根据自我评估获得有关牙齿状况和咀嚼困难的信息。结果多颗牙缺失者和咀嚼坚硬食物困难者的认知功能障碍发生率显著高于其他两组。当调整性别，年龄和教育程度时，有自然牙齿的人和有多颗牙齿脱落的人之间的认知障碍的几率没有显著差异，但即使调整性别，年龄，教育，抑郁症和精神疾病，咀嚼困难的人的认知障碍的几率仍然显着较高。结论：性别、年龄、教育程度和某些疾病不能解释认知能力和咀嚼能力之间的关系。只要长者没有咀嚼困难，无论他们是用天然牙齿还是假牙咀嚼，都不会对认知能力造成重大影响。研究结果进一步证明了咀嚼能力与老年人认知障碍之间的联系。
Objectives To determine whether there is an association between tooth loss, chewing ability, and cognitive function in a general elderly population. Design Data from the Panel Study of Living Conditions of the Oldest Old in 2002 were analyzed. Stepwise logistic regression analyses were used to examine the relationship between cognitive function and tooth loss and chewing ability. Participants Five hundred fifty-seven persons who were nationally representative of the Swedish population aged 77 and older. Measurements Cognitive function was measured using the abridged version of the Mini-Mental State Examination. Information on dental status and chewing difficulty was obtained according to self-assessment. Results Persons with multiple tooth loss and persons with difficulty chewing hard food had significantly higher odds of cognitive impairment. When adjusted for sex, age, and education, the odds of cognitive impairment were not significantly different between persons with natural teeth and with multiple tooth loss, but the odds of impairment remained significantly higher for persons with chewing difficulty even when adjusted for sex, age, education, depression, and mental illness. Conclusion Sex, age, education, and certain illnesses do not explain the association between cognition and chewing ability. Whether elderly persons chew with natural teeth or prostheses may not contribute significantly to cognitive impairment as long as they have no chewing difficulty. The results add to the evidence of the association between chewing ability and cognitive impairment in elderly persons.
