摘要

背景：饮茶，特别是不同类型的饮茶与认知功能之间的关系尚未得到充分的探讨。在考虑选择偏差的情况下，本研究旨在探讨饮茶状态、饮茶频率和饮茶类型与认知功能的关系。方法：采用2018年中国纵向健康寿命调查（CLHLS）的数据（N = 8498）。采用简易精神状态检查（MMSE）测量认知功能。采用Logistic和线性回归分别评估饮茶与认知障碍和认知评分的关系。使用倾向评分匹配（PSM）和处理加权逆概率（IPTW）来平衡组间特征差异。结果：使用PSM和IPTW后，两组间饮茶状态、饮茶频次、饮茶类型等特征均达到较好的平衡。喝茶与较少的认知障碍（or调整系数：0.84,ORPSM:0.84, ORIPTW:0.87）和较高的认知得分（调整系数：0.29，系数psm:0.33，系数ptw:0.29）相关。经常喝茶的人可能比从不或很少喝茶的人有更好的认知功能（p趋势调整：0.71，偏倚系数：0.75）和更高的认知得分（系数调整：0.45，系数调整：0.54）。男性、未受教育人群和年收入在10万人民币以下的人群更有可能从花茶中受益。茶叶消费与年龄、教育程度和收入之间存在显著的相互作用。结论：即使在PSM和IPTW调整后，茶的摄入，尤其是常规茶和绿茶的摄入，与较少的认知障碍和更高的认知得分有关。花茶可能具有潜在的保护作用，值得进一步研究。年龄、受教育程度和收入与饮茶对认知功能有协同效应。

Tea consumption and cognitive health in Chinese older adults: A propensity score matching and weighting analysis

Background

The association between tea consumption, especially different types, and cognitive function has not been adequately explored. This study aimed to investigate the associations of tea consumption, including status, frequency, and type, with cognitive function, considering selection bias.

Methods

We used data from the Chinese Longitudinal Healthy Longevity Survey (CLHLS) in 2018(N = 8498). Cognitive function was measured by Mini-Mental State Examination (MMSE). Logistic and linear regression were applied to assess the associations of tea consumption with cognitive impairment and cognitive scores, respectively. Propensity score matching (PSM) and inverse probability of treatment weighting (IPTW) were used to balance characteristic differences between groups.

Results

The characteristics of tea consumption status, frequency and type were well balanced between groups after using PSM and IPTW. Drinking tea was associated with less cognitive impairment (OR_adjusted:0.84, OR_PSM:0.84, OR_IPTW:0.87) and higher cognitive scores (Coefficient_adjusted:0.29, Coefficient_PSM:0.33, Coefficient_IPTW:0.29). Regular tea drinkers may have better cognitive function than those who never or rarely consumed (P_trend < 0.05 for both methods). Green tea drinkers had lower prevalence of cognitive impairment (OR_adjusted:0.71, OR_IPTW:0.75) and higher cognitive scores (Coefficient_adjusted:0.45, Coefficient_IPTW:0.54). Men, uneducated, and those with annual income>10,000 RMB were more likely to benefit from flower tea. Significant interactions of tea consumption with age, education and income were observed.

Conclusions

Tea consumption, especially regular and green tea consumption, was associated with less cognitive impairment and higher cognitive scores, even after PSM and IPTW adjustments. Flower teas may have potential protective effect that is worth further study. Age, education and income have synergistic effects with tea consumption on cognitive function.

期刊介绍： Archives of Gerontology and Geriatrics provides a medium for the publication of papers from the fields of experimental gerontology and clinical and social geriatrics. The principal aim of the journal is to facilitate the exchange of information between specialists in these three fields of gerontological research. Experimental papers dealing with the basic mechanisms of aging at molecular, cellular, tissue or organ levels will be published. Clinical papers will be accepted if they provide sufficiently new information or are of fundamental importance for the knowledge of human aging. Purely descriptive clinical papers will be accepted only if the results permit further interpretation. Papers dealing with anti-aging pharmacological preparations in humans are welcome. Papers on the social aspects of geriatrics will be accepted if they are of general interest regarding the epidemiology of aging and the efficiency and working methods of the social organizations for the health care of the elderly.
