背景由于口腔器官的功能处于吞咽过程的第一阶段，吞咽功能的下降可能部分与口腔虚弱有关。目的探讨日本社区老年人吞咽功能与口腔功能的关系，并提出吞咽功能减退的筛查界值。方法对188名被试进行问卷调查。统计现有牙数和功能牙数。检测舌苔细菌数、口腔润湿性、舌压、口腔动力、咀嚼能力和咬合力。吞咽功能使用10项进食评估工具(EAT-10)进行评估。用受试者工作特性曲线确定各口腔功能参数的临界点。采用Logistic回归模型来确定具有最高准确率的参数组合，以区分吞咽功能下降和正常。结果ODK/pa/Sound为6.2次/s者吞咽问题发生率高于6.2次/s及以上者。EAT-10得分1分或以上与年龄(71岁；优势比[OR]4.321)和ODK/pa/Sound降低(<；6.2次/秒；OR 2.914)显著相关。结论在日本社区老年人中，疑似有吞咽功能减退的老年人口腔功能低于无吞咽功能减退的老年人，其临界值为71岁，Odk/pa/Sound 6.2次/S。
Background Since oral organs function in the first stage of the swallowing process, it is possible that decline in swallowing function can be partly related to oral frailty. Aims The purpose of this study was to investigate the association between swallowing function and oral function among community-dwelling elderly Japanese and to propose cut-off values for screening of decline in swallowing function. Methods A total of 188 participants were included in the analysis. The number of present teeth and functioning teeth were counted. Bacteria counts in tongue coat, oral wettability, tongue pressure, oral diadochokinesis (ODK), masticatory ability and bite force were examined. Swallowing function was assessed using the 10-item Eating Assessment Tool (EAT-10). Receiver operating characteristic curves were used to determine the cut-off points of each oral function parameter. A logistic regression model was performed to determine the combination of parameters with the highest accuracy for differentiating decline in swallowing function from normal. Results Subjects with ODK /pa/ sound < 6.2 times/second had higher prevalence of swallowing problems than those with 6.2 times/second or more. EAT-10 scores of one or more were significantly related to older age (>= 71 years old; odds ratio [OR] 4.321) and reduced ODK /pa/ sound (< 6.2 times/second; OR 2.914). Conclusions Among community-dwelling elderly Japanese, those who were suspected of having decline in swallowing function had lower oral function than those who did not, and the cut-off values were 71 years of age and ODK /pa/ sound 6.2 times/s.
