在老年人中，较高的大脑功能质量是进行日常生活活动的一个促成因素。这项研究的目的是从流行病学角度阐明咀嚼和较高的大脑功能之间的联系。共有208名70-74岁的社区老年人参加了调查。自我评估的咀嚼能力(咀嚼能力)被分为三类：咀嚼各种食物的能力，只咀嚼略硬的食物的能力，或只咀嚼软的或泥的食物的能力。脑功能通过四项神经心理测试进行评估：瑞文彩色递进矩阵(RCPM)测试，言语配对联想1(VerPA)任务和视觉配对联想1任务(韦氏记忆量表修订版)，以及区块设计分测试(韦氏成人智力量表第三版)。使用Spearman等级相关系数检验咀嚼能力与每个测试之间的相关性。以神经心理测试为因变量，咀嚼能力为主要自变量，对年龄、性别、文化程度、社会活动、饮酒/吸烟习惯、慢性疾病和牙齿状况进行多因素Logistic回归分析。在RCPM测试、VerPA任务、积木设计测试与咀嚼能力之间存在显著的相关性。在多项Logistic回归模型中，咀嚼能力差与Mean-S.D.下的类别显著且独立相关。与平均值+/-S.D.的积分比较RCPM测试和VerPA任务的范围。在老年人中，咀嚼和较高的大脑功能之间可能存在显著的关联。
Among the elderly, the quality of higher brain function is a contributing factor in performing activities of daily living. The aim of the study is to elucidate, epidemiologically, associations between mastication and higher brain function. A total of 208 community-dwelling elderly persons, aged 70-74 years, were enrolled. Self-assessed masticatory ability (masticatory ability) was classified into one of three categories: ability to chew all kinds of food, ability to chew only slightly hard food, or ability to chew only soft or pureed food. Brain function was assessed by four neuropsychological tests: Raven's Colored Progressive Matrices (RCPM) test, the Verbal Paired Associates 1 (VerPA) task and the Visual Paired Associates 1 task (from the Wechsler Memory Scale Revised Edition), and the Block Design subtest (from the Wechsler Adult Intelligence Scales-Third Edition). Correlations between masticatory ability and each test were examined using Spearman rank correlation coefficients. Multinominal logistic regression models were conducted with the neuropsychological tests as the dependent variables and masticatory ability as the principal independent variable to adjust for age, gender, educational background, social activity, drinking/smoking habits, chronic medical conditions and dental status. Significant correlations were found between the RCPM test, the VerPA task, the Block Design test and masticatory ability. In multinominal logistic regression models, poor masticatory ability was significantly and independently related to the categories under the mean-s.d. points compared with those of the mean +/- s.d. ranges for RCPM test and the VerPA task. Significant associations may exist between mastication and higher brain function among the elderly.
