Am J Clin Nutr:猜猜素食者和非素食者,谁更容易死?

2015-12-16 Seven L 译 MedSci原创

已有研究表明,素食者某些慢性疾病发生率低于非素食者,但是否会降低死亡率尚不明确。研究者进行了一项大型队列研究,调查英国素食者和非素食者死亡率比较。该研究分析的数据来自2项前瞻性研究,涉及居住在英国的60,310名居民,其中18,431名经常吃肉的人(平均≥5次/周)、13,039名不经常吃肉、8516名肉类中只吃鱼的人、20,324名素食者(其中2228名为严格素食者,不吃任何与动物相关的食物)。

已有研究表明,某些慢性疾病在素食者中的发生率会低于非素食者,但是否会降低死亡率尚不明确。研究者进行了一项大型队列研究,对英国素食者和非素食者死亡率进行了调查比较。

该研究分析的数据来自2项前瞻性研究,涉及居住在英国的60,310名居民,其中18,431名经常吃肉的人(平均≥5次/周)、13,039名不经常吃肉、8516名肉类中只吃鱼的人、20,324名素食者(其中2228名为严格素食者,不吃任何与动物相关的食物)。

研究数据显示,随访期间有5294例在90岁之前死亡。经数据分析后全因死亡率在不同因素组之间无差异:少肉、只吃鱼、素食与经常吃肉的组相比,其HR分别为:0.93 (95% CI: 0.86, 1.00)、0.96 (95% CI: 0.86, 1.06)、1.02 (95% CI: 0.94, 1.10)(P= 0.082)。不过常吃肉的人群在以下方面与其他组存在差异,循环系统疾病死亡率在只吃鱼组会更高(HR: 1.22; 95% CI: 1.02, 1.46);恶性肿瘤死亡率在只吃鱼组更低 (HR: 0.82; 95% CI: 0.70, 0.97),包括胰腺癌死亡率在少吃肉和素食组中更低 (HR: 0.55; 95% CI: 0.36, 0.86 、HR: 0.48; 95% CI: 0.28, 0.82),淋巴和造血组织的癌症死亡率在素食组更低 (HR: 0.50; 95% CI: 0.32, 0.79),呼吸系统疾病死亡率在少吃肉组更低(HR: 0.70; 95% CI: 0.53, 0.92),还有其他因素死亡率在少吃肉组也更低(HR: 0.74; 95% CI: 0.56, 0.99)。对BMI校正后,以上联系并没有发生大的改变。

研究结果表明,对英国人群进行调查后,素食者和非素食者之间全因死亡率并没有差异,但在具体某个领域的死亡率差异显著,值得未来进一步的调查研究。
