前言：虽然以前的研究已经确定了与咀嚼性能相关的各种因素，但哪些因素影响咀嚼性能的纵向变化还没有弄清楚。目的：在日本城市人口的纵向研究中，我们旨在阐明与咀嚼性能变化有关的因素，并根据与咀嚼性能相关的因素构建模型。方法：Suita研究共纳入1005名日本受试者(男性411人，女性594人；基线平均年龄65.7±7.7岁；平均随访期5.0±0.9年)。这些受试者在基线(2008年6月至2011年12月)和随访(2013年6月至2017年1月)时都参加了牙科检查。记录功能牙和咬合支撑区的数量，并使用Eichner指数对后者进行评估。根据社区牙周指数评价受试者的牙周状况。咀嚼性能是用测试胶冻测定的。结果：在以随访期咀嚼效能为因变量的多元线性回归分析中，基线年龄、咀嚼效能、功能牙数和最大咬合力是显著的自变量。通过基线咬合支持的多元线性回归分析结果发现，只有艾克纳A级受试者的基线最大咬合力和艾克纳B级受试者的基线年龄、咀嚼性能和功能牙数是影响随访时咀嚼性能的显著自变量。结论：我们的研究表明，咀嚼性能的纵向变化与年龄、功能牙数、KNOWLEDGE TRANSFER声明：患者和临床医生应该认识到客观和定量评估咀嚼效率的重要性，并理解各种因素与咀嚼性能的纵向变化有关。本研究结果可为不同咬合支撑区数目的老年人预防或改善咀嚼效能下降提供基础数据。
INTRODUCTION: Although previous studies have identified various factors related to masticatory performance, which factors affect longitudinal changes in masticatory performance have not been clarified.OBJECTIVES: We aimed to clarify factors involved in changes to masticatory performance and construct models from factors related to masticatory performance in a longitudinal study of a general urban population in Japan.METHODS: A total of 1,005 Japanese subjects (411 men, 594 women; mean age at baseline, 65.7 ± 7.7 years; mean follow-up period, 5.0 ± 0.9 years) were included in the Suita study. These subjects participated in dental checkups both at baseline (June 2008-December 2011) and at follow-up (June 2013-January 2017). The number of functional teeth and occlusal support areas was recorded and the latter assessed using the Eichner index. Subjects' periodontal status was evaluated based on the Community Periodontal Index. Masticatory performance was determined using test gummy jelly. Factors affecting masticatory performance at follow-up and the degree of their effect were investigated by multiple linear regression analysis.RESULTS: In multiple linear regression analysis with masticatory performance at follow-up as the dependent variable, baseline age, masticatory performance, number of functional teeth, and maximum bite force were significant independent variables. The results of multiple linear regression analyses by occlusal support at baseline identified only maximum bite force at baseline in subjects who were Eichner A and baseline age, masticatory performance, and number of functional teeth in subjects who were Eichner B as significant independent variables concerning masticatory performance at follow-up.CONCLUSION: Our study showed a relationship between longitudinal changes in masticatory performance and age, number of functional teeth, and maximum bite force and furthermore showed that the effects of these factors vary according to the residual number of occlusal support areas.KNOWLEDGE TRANSFER STATEMENT: Patients and clinicians should recognize the importance of objective and quantitative assessment for chewing efficiency and understand that various factors are related to longitudinal changes in masticatory performance. The results of this study can provide basic data for preventing or improving the decline in masticatory performance for elderly people with varying numbers of occlusal support areas.
