Tea consumption has been reported to be associated with lowered risk of cardiovascular disease, stroke and osteoporosis that cause functional disability, but its association with physical function has not been investigated directly.
We examined the association between tea consumption and performance in gait and balance, instrumental and basic activities of daily living (IADL and BADL) in a cross-sectional study of community-living older persons.
Baseline data of 2398 adults aged ≥ 55 years in the Singapore Longitudinal Ageing Studies who completed self-reported current tea consumption, Performance Oriented Mobility Assessment (POMA) of gait and balance, and self reports of BADL and IADL were analyzed.
In multivariate analyses controlling for age, gender, education, housing type, co-morbidities, hospitalization, arthritis and hip fracture, GDS depression score, MMSE cognitive score, body mass index, creatinine, serum albumin, haemoglobin, physical activities score and coffee consumption, tea consumption was positively associated with better balance (β=0.06, p<0.01), gait (β=0.01, p=0.02), IADL (β=0.03, p=0.01) and BADL (β=0.01, p=0.05). Strongly positive associations were observed for black/oolong tea in multivariate analyses, and for green tea consumption only in univariate analysis, whereas coffee consumption was not associated at all.
Tea consumption was associated with better physical functional performances in community-living older adults.
据报道，饮茶与降低导致功能残疾的心血管疾病、中风和骨质疏松症的风险有关，但其与身体功能的关联尚未得到直接研究。
在一项针对社区居住老年人的横断面研究中，我们研究了饮茶与步态、平衡能力以及日常生活工具性活动和基本活动（IADL和BADL）表现之间的关联。
分析了新加坡纵向老龄化研究中2398名年龄≥55岁成年人的基线数据，这些成年人完成了自我报告的当前饮茶情况、步态和平衡能力的定向运动能力评估（POMA）以及BADL和IADL的自我报告。
在对年龄、性别、教育程度、住房类型、合并症、住院情况、关节炎和髋部骨折、老年抑郁量表（GDS）抑郁评分、简易精神状态检查表（MMSE）认知评分、体重指数、肌酐、血清白蛋白、血红蛋白、身体活动评分和咖啡摄入量进行多变量分析时，饮茶与更好的平衡能力（β=0.06，p<0.01）、步态（β=0.01，p=0.02）、IADL（β=0.03，p=0.01）和BADL（β=0.01，p=0.05）呈正相关。多变量分析中观察到红茶/乌龙茶有强正相关，单变量分析中仅绿茶消费有强正相关，而咖啡消费则完全没有关联。
饮茶与社区居住老年人更好的身体功能表现有关。
