以前的纵向研究发现认知功能会影响口腔健康,反之亦然。然而,缺乏同时对认知功能和非端主义之间的相互关系的研究,尤其是在发展中国家。本研究旨在探讨中国中老年人的认知功能与无动症之间的相互关系。
数据来自2011年和2015年中国健康与退休纵向研究的浪潮。样本包括14038名45岁或以上的受访者。采用双波交叉滞后分析对假设模型进行检验。
在45-59岁的被调查者中,基线认知功能与随后的无牙症相关[b=-0.017,标准差(SD)=0.006,P<0.01]。相比之下,在随访波时,基线无牙症与认知功能较差无明显相关性(b=-0.744,SD=0.383,P>0.05)。然而,在60岁或以上的受访者中,基线认知功能与随后的无牙症相关(b=-0.017,SD=0.005,P<0.01),基线无牙与随访后认知功能降低有关(b=-0.419,SD=0.143,P<0.01)。
这些研究结果证明了认知功能和思想主义之间的相互关系。然而,这种关系因年龄组而异。这项研究证明了开发计划和服务以促进认知和口腔健康的重要性。特别是对于那些年龄较大的人。
Previous longitudinal studies have found that cognitive function affected oral health, and vice versa. However, research is lacking on the reciprocal relationships between cognitive function and edentulism simultaneously, especially in developing countries. The present study aimed to examine the reciprocal relationship between cognitive function and edentulism among middle-aged and older adults in China.
Data were derived from the 2011 and 2015 waves of the China Health and Retirement Longitudinal Study. The sample included 14,038 respondents aged 45 or older. A two-wave cross-lagged analysis was adopted to test the hypothesized model.
Among respondents aged 45-59, baseline cognitive function was associated with subsequent edentulism [b = -0.017, standard deviation (SD) = 0.006, P < 0.01]. In contrast, baseline edentulism was not significantly associated with poorer cognitive function at the follow-up wave (b = -0.744, SD = 0.383, P > 0.05). However, among respondents aged 60 or older, baseline cognitive function was associated with subsequent edentulism (b = -0.017, SD = 0.005, P < 0.01), and baseline edentulism was also associated with follow-up lower levels of cognitive function (b = -0.419, SD = 0.143, P < 0.01).
These findings demonstrated the reciprocal relationships of cognitive function and edentulism. However, such relationships varied across age groups. This study demonstrates the importance of developing programs and services to promote both cognitive and oral health, especially for those in older age.
