目的：分析饮茶对于脑梗死发病风险的影响。方法采用前瞻性队列研究方法，以96604人（男性76864，女性19740人）作为观察队列，依据2006＿2008年健康问卷的饮茶频率分为从不饮茶、偶尔饮茶、经常饮茶共3组，平均随访4.02年，用 Cox 风险比例回归模型分析饮茶频率对脑梗死发病的影响。结果（1）在从不饮茶、偶尔饮茶及经常饮茶组的脑梗死累积发病率为1.517％（868/65223）、0.852％（163/22869）、1.998％（143/8512），差异有统计学意义（χ2＝69.560，P ＝0.000）。（2）多因素 Cox 风险比例回归模型校正性别、年龄、腰围、血压、血糖、血脂及主要病史、吸烟、饮酒、摄盐等因素后显示，各饮茶组的脑梗死的的风险比（95％ CI）分别为1.000、0.713（0.597＿0.852）、0.986（0.814＿1.193）。结论本研究发现适度饮茶可以降低脑梗死的发病风险。

Objective To study the association between tea consumption and risk of brain infarction. Methods In this prospective cohort study,76 864 men and 19 740 women were included and were divided into never drink tea group,occa-sionally tea group and often tea group according to the frequency of tea intake which were collected during 2006 _ 2008 by questionnaire. The study was followed up for an average of 4. 02 years. The relationship between the frequency of tea intake and risk of brain infarction was estimated using the Cox proportional hazards regression analysis. Results (1)The cumulate inci-dence of brain infarction for categorizations of tea consumption were 1. 517%(868 / 65 223),0. 852%(163 / 22 869),1. 998%(143 / 8 512).(2)The multiple-adjusted HR(95% CI)of brain infarction across categorizations of tea intake were 1. 000 (ref),0. 713(0. 597 _ 0. 852),0. 986(0. 814 _ 1. 193). Conclusion In this community-based study,our findings is that moderate drinking can reduce the risk of cerebral infarction.
