老年人咬合支持状态与生活自理能力的相关性研究

目的：探讨老年人咬合支持状态对生活自理能力的影响。方法：设计调查表，收集1219名65-74岁老年人咬合支持状态和日常生活自理能力方面的信息，分析两者之间的相关关系。应用多元Logistic回归分析探讨两者之间的相关关系。结果：1219名老年人中平均失牙9.1颗，其中343例（28.1％）的老年人口内没有咬合接触区。93名有轻度或重度的生活自理能力受损。日常生活自理能力受损者比例随着口内咬合支持区数目的增加而呈现下降的趋势；统计学分析有显著性负相关（P〈0．05）。结论：老年人群生活自理能力与其咬合支持区的数目存在关联性。

Study on the relationship between state of occlusal support and activities of daily life in aged group

Objective： This study is to investigate the relationship between state of occlusal support and activities of daily life（ADL） in elders from 65-74 years old. Methods： Cross section study was adopted and questionnaire was designed to collect the information about state of occlusal support and relevant ADL of 1219 elders from 65 to 74 years old living in urban area of Beijing city. The statistic dependence and the degree of relationship between the above two criteria were analyzed using the method of multivariate logistic regression analysis. Results： The elders among this group lost average 9.1 teeth, and 343（28.1%） of them had no any occlusal contact. 93 elders had trouble to care of themselves life. There were significantly negative relevant correlations between the state of occlusal support and ADL（P〈0.05）. With the increasing of number of occlusal support area, the dependency of ADL decreased. The index of ADL was lower with less number of occlusal support areas than those with more number of occlusal support areas. Conclusion： ADL had correlation with the number of occlusal support areas.
