Nat Commun:血清视黄醇水平越高,长期死亡风险越低!

2021-11-09 Nebula MedSci原创

动物产品是视黄醇的主要食物来源,包括肝脏、黄油、牛奶、奶酪和鸡蛋

维生素 A 是一类必需的脂溶性化合物,其中视黄醇是维生素 A 在循环中的主要形式,被认为是人体维生素 A 状态的生化指标。动物产品是视黄醇的主要食物来源,包括肝脏、黄油、牛奶、奶酪和鸡蛋。

缺乏维生素 A 会导致干眼症和失明、感染和炎症、慢性疾病,甚至死亡。但视黄醇作为维生素 A 状态的临床指标,其与人类长期死亡率之间的关系尚不明确。

基于人群的研究表明,循环视黄醇与癌症、血管疾病 (CVD) 和死亡风险之间存在不一致的相关性。本文报告了一项前瞻性分析的结果,该分析评估了血清视黄醇水平与总体和特定原因死亡风险之间的相关性。

血清视黄醇水平与总死亡率的相关性

在随访了长达 30 年的队列研究中,29,104 位男性中死亡了 23,797 位。与视黄醇水平最低的男性相比,血清视黄醇水平较高的参与者的总体死亡率、心血管疾病、心脏病和呼吸系统疾病死亡率均显著降低,死亡风险降低高达 17-32%(p<0.0001)。

血清视黄醇水平与心血管疾病死亡率的相关性

最后,在吸烟强度、饮酒量、体重指数、试验补充剂、血清 α-生育酚和 β-胡萝卜素水平以及随访时间不同的亚组分析中,视黄醇与总死亡率的相关性均相似。

总而言之,该研究结果表明,较高的血清视黄醇水平与较低的总体死亡率相关,包括心血管、心脏和呼吸系统疾病的死亡风险
