摘要目的:探讨老年人共病与口腔健康的关系。方法:回顾性分析，入选2017年7月至2018年7月在重庆医科大学附属第一医院老年科住院的患者852例，男性380例，女性472例，年龄60~74岁274例，75~89岁519例，≥90岁59例。收集患者的临床资料和汉化版简明口腔健康检查量表(BOHSE)评分，计算疾病累计评分(CIRS)，比较共病组(808例，94.8%)和非共病组(44例)患者汉化版BOHSE量表中口腔健康指标分布，多元线性回归分析共病组患者CIRS得分与口腔健康的关系。结果:808例共病组患者中，每例病种个数为(4.13±1.62)个，CIRS为(10.96±4.37)分；60~74岁、75~89岁、≥90岁患者病种个数(3.63±1.33)个/例、(4.26±1.64)个/例、(5.14±1.90)个/例( F＝35.555， P<0.01)，CIRS得分(8.88±3.59)分、(11.67±4.32)分、(13.64±4.42)分( F＝51.532， P<0.01)。住院老年患者口腔问题发生率为92.72%(790/852)，口腔健康的BOHSE得分为(4.58士2.88)分，60~74岁、75~89、≥90岁患者口腔健康状况比较差异有统计学意义( F＝19.370， P<0.05)。共病组与非共病组患者牙齿周围和(或)义齿覆盖的牙龈、天然牙和义齿状况比较，差异有统计学意义(均 P<0.05)。共病组患者CIRS得分与天然牙状况得分、咀嚼位牙齿咬合状况(包括天然牙及人工牙)得分相关( t值分别为2.565、2.495，均 P<0.05)。 结论:住院老年患者共病率高，口腔健康问题普遍，随增龄共病的病种个数增多、口腔健康状况越差，天然牙状况、咀嚼位牙齿咬合状况(包括天然牙及人工牙)与老年共病的疾病严重程度相关。

abstractsObjective:To explore the relationship between comorbidity and oral health in the elderly.Methods:As a retrospective study, 852 patients hospitalized at the Department of Geriatrics, the First Affiliated Hospital of Chongqing Medical University between July 2017 and July 2018 were selected, including 380 male and 472 female patients, with 274 between 60 and 74 years old, 519 between 75 and 89 years old and 59 ≥90 years old.Patients' clinical data and records on the Chinese version of the Kayser-Jones Brief Oral Health Status Examination(BOHSE)were retrospectively collected.The cumulative illness rating scale(CIRS)and the Chinese version of the BOHSE scale were calculated.The distribution of oral health problems measured using indicators in the Chinese version of the BOHSE scale was compared between the comorbidity group and the non-comorbidity group.The relationship between the CIRS score and oral health was analyzed by multiple linear regression.Results:Of the 808 patients with comorbidities, each patient had(3.63±1.33), (4.26±1.64)and(5.14±1.90)diseases, respectively, in the 60-74, 75-89 and ≥90 age groups( F=35.555, P<0.01). The age groups' CIRS scores were(8.88±3.59), (11.67±4.32)and(13.64±4.42)( F=51.532, P<0.01). The incidence of oral problems in hospitalized elderly patients was 92.72 %(790/852). The average oral health BOHSE score was(4.58 ± 2.88). There was a significant difference in oral health condition among the 60-74, 75-89 and ≥90 age groups( F=19.370, P<0.05). There were also significant differences in gums between teeth and/or under artificial teeth, condition of natural teeth and condition of artificial teeth between hospitalized elderly patients with and without comorbidities(all P<0.05). CIRS scores of patients with comorbidities were correlated with scores of natural tooth condition and pairs of teeth in the chewing position(natural or artificial)( t values were 2.565 and 2.495, P<0.05 for both). Conclusions:The comorbidity rate of hospitalized elderly patients is high and their oral health problems are common.As the age increases, the number of comorbidities increases and oral health condition becomes worse.The natural tooth condition and pairs of teeth in the chewing position(natural or artificial)are related to the severity of comorbidities in the elderly.
