脑部中风是一种急性脑血管病。 因其发病大多数比较急骤，故又称“脑血管意外”，还常叫作“脑卒中”。中风极度危险且死亡率极高，据统计：全球大概有百分之10的死亡来自中风。中风不仅危险，且年期人的病发率正在逐渐上升。
但最近一项针对 50-74 岁健康人群的研究发现，喝咖啡或茶可能与降低中风和痴呆症的风险有关。喝咖啡还与中风后痴呆的风险降低有关。
来自中国天津天津医科大学的 Yuan Zhang 及其同事研究了来自英國生物樣本库的 365,682 名参与者，这些参与者于 2006 年至 2010 年期间被招募，并一直跟踪到 2020 年。
一开始，参与者自我报告了他们的咖啡和茶摄入量。在研究期间，5,079 名参与者患上了痴呆症，10,053 人至少经历了一次中风。
每天喝 2-3 杯咖啡或 3-5 杯茶，或同时喝 4-6 杯咖啡和茶的人中风或痴呆的发生率最低。
与既不喝咖啡也不喝茶的人相比，每天喝 2-3 杯咖啡和 2-3 杯茶的人患中风的风险降低 32%，患痴呆症的风险降低 28%。
单独或与茶一起摄入咖啡也与中风后痴呆的风险降低有关。
此外，相对较少的人会患上痴呆症或中风，这使得很难将发病率准确地外推到更大的人群中。
最后，虽然喝咖啡和茶可能对中风、痴呆和中风后痴呆有保护作用，但不能从这些关联中推断出这种因果关系。
Drinking coffee or tea may be associated with a lower risk of stroke and dementia, according to a study of healthy individuals aged 50-74. Drinking coffee was also associated with a lower risk of post-stroke dementia.
Strokes are life-threatening events which cause 10 percent of deaths globally. Dementia is a general term for symptoms related to decline in brain function and is a global health concern with a high economic and social burden. Post-stroke dementia is a condition where symptoms of dementia occur after a stroke.
Yuan Zhang and colleagues from Tianjin Medical University, Tianjin, China studied 365,682 participants from the UK Biobank, who were recruited between 2006 and 2010 and followed them until 2020.
At the outset participants self-reported their coffee and tea intake. Over the study period, 5,079 participants developed dementia and 10,053 experienced at least one stroke.
People who drank 2-3 cups of coffee or 3-5 cups of tea per day, or a combination of 4-6 cups of coffee and tea had the lowest incidence of stroke or dementia.
Individuals who drank 2-3 cups of coffee and 2-3 cups of tea daily had a 32% lower risk of stroke and a 28% lower risk of dementia compared with those who drank neither coffee nor tea.
Intake of coffee alone or in combination with tea was also associated with lower risk of post-stroke dementia.
he UK Biobank reflects a relatively healthy sample relative to the general population which could restrict the ability to generalize these associations.
lso, relatively few people developed dementia or stroke which can make it difficult to extrapolate rates accurately to larger populations.
Finally, while it’s possible that coffee and tea consumption might be protective against stroke, dementia and post-stroke dementia, this causality cannot be inferred from the associations.
The authors add of their findings, published in PLOS Medicine, that they “suggested that moderate consumption of coffee and tea separately or in combination were associated with lower risk of stroke and dementia.”
