Although tea consumption has been reported to have various health benefits in humans, its association with health-related quality of life (HRQOL) has not been investigated directly. We aimed to examine the relationship between tea consumption and HRQOL among older Chinese adults.
We analyzed community-based cross-sectional data of 5,557 older Chinese individuals aged 60 years or older who participated in the Weitang Geriatric Diseases study. Information on tea consumption and HRQOL assessed by the European Quality of Life-5 dimensions (EQ-5D) were collected by questionnaires. We estimated the relationship of tea consumption and the EQ-5D index score using linear regression models and the association between tea consumption and self-reported EQ-5D health problems using logistic regression models.
The EQ-5D index score was higher for habitual tea drinkers than their counterparts. In multivariate linear analyses controlling for socio-demographic conditions, health conditions, and lifestyle habits, the differences in ED-5D index score between individuals with and without tea drinking habits was 0.012 (95% confidence interval, 0.006-0.017). In multivariate logistic analyses, habitual tea drinking was inversely associated with reporting of problems in EQ-5D dimensions mobility (odds ration [OR], 0.44; 95% CI: 0.23-0.84); pain/discomfort (OR, 0.74; 95% CI: 0.61-0.90); and anxiety/depression (OR, 0.60; 95% CI: 0.38-0.97). These associations were more evident for black or oolong tea than green tea.
Habitual tea consumption was associated with better HRQOL in older adults.
尽管据报道饮茶对人类有多种健康益处，但其与健康相关生活质量（HRQOL）的关联尚未得到直接研究。我们旨在探讨中国老年人群中饮茶与HRQOL之间的关系。
我们分析了5557名年龄在60岁及以上、参与渭塘老年疾病研究的中国老年人的社区横断面数据。通过问卷调查收集了关于饮茶情况以及由欧洲生活质量五维度量表（EQ-5D）评估的HRQOL信息。我们使用线性回归模型估计饮茶与EQ-5D指数得分之间的关系，并使用逻辑回归模型估计饮茶与自我报告的EQ-5D健康问题之间的关联。
经常饮茶者的EQ-5D指数得分高于不常饮茶者。在控制社会人口学状况、健康状况和生活方式习惯的多变量线性分析中，有饮茶习惯和无饮茶习惯者之间的ED-5D指数得分差异为0.012（95%置信区间，0.006 - 0.017）。在多变量逻辑分析中，经常饮茶与EQ-5D维度中的活动能力问题报告呈负相关（比值比[OR]，0.44；95%置信区间：0.23 - 0.84）；疼痛/不适（OR，0.74；95%置信区间：0.61 - 0.90）；以及焦虑/抑郁（OR，0.60；95%置信区间：0.38 - 0.97）。这些关联在红茶或乌龙茶中比绿茶中更为明显。
经常饮茶与老年人更好的HRQOL相关。
