本研究旨在阐明社区无牙列老年人戴全口义齿的咀嚼能力与体能表现之间的关系。以前的研究已经显示了口腔条件和这些参数之间的关系。本研究以全口义齿佩戴者为研究对象。方法研究对象为210名年龄65岁、戴全口义齿的无牙列成年人。检查了以下口腔条件：通过变色口香糖测量的咀嚼能力，被认为可咀嚼的食物数量，使用假牙时的疼痛和义齿基托适合性。采用握力(HG)和单腿睁眼站立时间(OLST)评定肌肉力量和静态平衡。计算Spearman‘s等级相关系数以检验口腔状况和体能表现之间的相关性。以各体能指标为因变量，口腔状况为自变量，建立正向逐步线性回归模型。结果口腔状况与体能状况无显著相关性。在男性中，可咀嚼食物的数量与HG之间以及颜色分数与OLST之间存在显著的正相关。在调整人口、社会和医疗条件等口腔条件后，逐步线性回归分析仍显示颜色得分与OLST显著相关。结论日本老年人全口义齿患者的咀嚼能力评价为混合能力可能与静态平衡有关。
ObjectiveThis study aimed to elucidate the association between masticatory ability and physical performance in community-dwelling edentulous older adults wearing complete dentures.BackgroundPhysical performance parameters are significant predictors of decreased activities of daily living. Previous studies have shown the relationships between oral conditions and these parameters. Here, we focused on complete denture wearers.MethodsTwo hundred and ten edentulous adults aged 65years and wearing complete dentures were enrolled. The following oral conditions were examined: masticatory ability measured by colour-changing chewing gum, number of foods considered chewable, pain when using dentures and denture base fit. Handgrip strength (HG) and one-leg standing time with eyes open (OLST) were used to evaluate muscle strength and static balance. Spearman's rank correlation coefficients were calculated to examine the correlations between oral conditions and physical performance. Forward stepwise linear regression models were applied with each physical performance parameters as the dependent variable and oral conditions as the independent variable.ResultsThe women did not show significant correlations between oral conditions and the physical performance. In men, significant and positive correlations were found between the number of chewable foods and HG, and between the colour scores and OLST. The significant correlation between the colour scores and OLST was still noted in the stepwise liner regression analysis after adjusting for demographic, social and medical conditions, and other oral conditions.ConclusionIn Japanese elderly edentulous men wearing complete dentures, masticatory ability evaluated as the mixing ability may be associated with static balance.
