目的：虽然牙齿缺失会导致咀嚼能力下降，这可能会影响营养状况，并损害个人的一般健康，包括体力活动，但在高龄人群中，咀嚼能力的下降是否会导致身体健康状况恶化，目前还知之甚少。因此，本研究评估了日本80岁老人的咀嚼能力或牙齿数量与身体健康指标的关系。设计：横断面调查。对象和方法：对居住在福冈县的1282名80岁老人进行调查。结果：咀嚼食物数和牙齿数与握力、伸腿力量、伸腿力量、步速、单腿站立时间等体质指标呈正相关。然而，在调整各种混杂因素后，使用多元回归分析或Logistic回归分析，牙齿数与体能之间的显著关系消失了。另一方面，即使在对这些混杂因素进行调整后，咀嚼能力与腿部伸肌力量、单腿站立时间或等速腿部伸肌力量等体能测量指标之间的关系仍然显著。结论：在80岁的人群中，感觉到的咀嚼能力(被认为可咀嚼的食物的数量)与体能之间存在关系。咀嚼能力可能是身体健康的一个独立预测因子，因此，旨在保持咀嚼能力的预防性口腔保健可能能够提高高龄个体的日常生活能力和生活质量。
OBJECTIVE: Although tooth loss causes a decrease in masticatory ability, which may influence nutritional status, and impair an individual's general health including physical activity, little is known whether a decrease in chewing ability could result in deterioration in physical fitness in a very elderly population. Thus, the present study evaluated the relationship of chewing ability or teeth number with measures of physical fitness in a sample of 80-years-old in Japan.DESIGN: Cross-sectional survey.SUBJECTS AND METHODS: A total of 1282 people who were 80-years old and resided in the Fukuoka Prefecture were approached. A total of 697 individuals (277 male, 420 female) agreed to participate.RESULTS: Chewing food number and teeth number were related positively with physical fitness measurements of hand grip strength, leg extensor strength, leg extensor power, stepping rate, and one-leg standing time. However, the significant relationship between the number of teeth and physical ability disappeared after adjustment for various confounders, using multiple regression analysis or logistic regression analysis. On the other hand, the relationship of chewing ability with physical fitness measurements of leg extensor strength, one-leg standing time, or isokinetic leg extensor power remained significant even after adjustment for these confounders.CONCLUSION: There is a relationship between perceived chewing ability (number of foods considered chewable) and physical fitness in this 80-year-old population. Chewing ability may be an independent predictor of physical fitness, thus preventative dental care aimed at preserving chewing ability may be able to enhance activities of daily life and quality of life in very elderly individuals.
