BMJ:食鱼者和素食者缺血性心脏病和中风的风险较食肉者低

2019-09-08 不详 MedSci原创

食肉者可能更容易出现心血管问题,因此,本项研究旨在探讨素食主义与缺血性心脏病和中风风险的关系。

背景及目的:
食肉者可能更容易出现心血管问题,因此,本项研究旨在探讨素食主义与缺血性心脏病和中风风险的关系。

方法:
本项研究是一项前瞻性研究,研究人员收集了在1993年至2001年期间英国的大部分非肉食者。其中 48188名没有缺血性心脏病,中风或心绞痛(或心血管疾病)病史,所有患者被分成三个不同的饮食组:肉食者(食用肉类的参与者,无论他们是否食用鱼类,乳制品或鸡蛋)(n = 28 364),食鱼者(消费的鱼但没有肉; n = 7506)和素食者(包括素食主义者(n = 16 254))。主要观察结局是缺血性心脏病和中风(包括缺血性和出血性类型)的事件的发生。

结果
本项研究随访时间超过18.1年,总共记录了2820例缺血性心脏病和1072例总卒中(519例缺血性卒中和300例出血性卒中)。在调整了社会人口统计学和生活方式混杂因素后,食鱼者和素食者分别有13%(风险比0.87,95%置信区间0.77至0.99)和22%(0.78,0.70至0.87)的缺血性心脏病发病率,低于食肉动物(异质性P <0.001)。这种差异相当于素食者中缺血性心脏病(95%置信区间减少6.7至13.1)的情况比10年内每1000人中的食肉者减少10例。调整自我报告的高血脂,高血压糖尿病和体重指数后,缺血性心脏病的关联部分减弱(风险比0.90,所有调整的素食者的95%置信区间为0.81至1.00。相比之下,素食者的总卒中率(危险比1.20,95%置信区间1.02-1.40)比食肉者高20%,相当于每1000人中有3例卒中总数(95%置信区间0.8~5.4)。

结论:
本项研究表明食鱼者和素食者的缺血性心脏病发病率低于肉食者,尽管素食者的出血率和总卒中率较高。
