在日本，老年痴呆症患者正在迅速增加。一些动物研究表明，老年人咀嚼功能下降与认知障碍之间存在关系。然而，对此进行的流行病学研究很少。采用流行病学方法，本研究调查了44名年龄在65岁以上的女性痴呆症患者和44名非痴呆症患者的这种关系。两组患者年龄、行走、进食、排泄、洗澡、穿衣等基本生活活动相匹配。使用修订后的Hasegawa痴呆评定量表测量受试者的认知障碍。咀嚼功能根据牙齿数量、最大咬合力、咬合接触面积和咀嚼评分进行评估。认知正常组的牙数明显高于认知障碍组（P < 0.05）。认知正常组的最大咬合力、咬合接触面积、咀嚼评分均显著高于认知障碍组（P < 0.01）。这些结果表明，老年人的咀嚼功能与认知状态有关。
In Japan, the elderly population suffering from dementia is rapidly increasing. Several animal studies have indicated a relationship between reduced masticatory function in the elderly subject and cognitive impairment. However, epidemiological studies examining this have been scarce. Using an epidemiological approach, the present study investigated this relationship in 44 females with and 44 without dementia, all aged over 65 years. Age and basic activities of daily living, such as walking, eating, excreting, bathing and dressing, were matched in the two groups. Cognitive impairment of the subjects was measured using the revised Hasegawa Dementia Rating Scale. Masticatory function was assessed in terms of the number of teeth present, maximum bite force, occlusal contact area, and mastication score. The number of teeth present in cognitively normal subjects was significantly higher than in cognitively impaired subjects (P < 0.05). In addition, maximum bite force, occlusal contact area, and mastication scores of cognitively normal subjects were significantly higher than those of cognitively impaired subjects (P < 0.01). These results suggest that masticatory function in the elderly person is associated with cognitive status.
