Purpose: To examine the relationship between oral intake function and oral health status in convalescent inpatients.

Methods: Subjects were 222 patients admitted to a convalescent hospital between 1 January and 30 June 2018. Investigation items were age, sex, causative disease, body mass index, functional oral intake scale (FOIS), functional independence measure, occlusal contact, assistance with oral cleaning, and oral health assessment tool (OHAT) scores. Multiple regression analysis was performed with FOIS as the dependent variable, and investigation items were related to FOIS as independent variables.

Results: Results of multiple regression analysis for all patients suggested that saliva and denture scores were significantly associated with FOIS. However, analysis excluding non-oral feeding patients did not show a significant association between FOIS and OHAT scores.

Conclusion: The results of this study suggest that oral health status is associated with oral intake function. In addition, the oral health status of inpatients may be strongly related to whether or not they are eating orally. Therefore, it is necessary to take good care of oral health in non-oral feeding patients in the convalescent ward.

目的：探讨康复期住院病人的口腔摄入功能与口腔健康状况之间的关系。

方法：对象为222名患者，于2018年1月1日至6月30日之间进入康复医院。调查项目为年龄，性别，病因，体重指数，功能性口腔摄入量表（FOIS），功能独立性量度，咬合接触，辅助治疗口腔清洁和口腔健康评估工具（OHAT）得分。以FOIS为因变量进行多元回归分析，调查项目与FOIS为自变量相关。

结果：所有患者的多元回归分析结果表明，唾液和义齿评分与FOIS显着相关。但是，排除非口服喂养患者的分析并未显示FOIS和OHAT评分之间存在显着相关性。

结论：本研究结果表明口腔健康状况与口腔摄入功能有关。另外，住院患者的口腔健康状况可能与他们是否口服饮食有很大关系。因此，有必要在康复病房的非口服喂养患者中注意口腔健康。
