CGH: 膳食麸质摄入不会增加美国成年人炎症性肠病的发病风险

2022-01-27 MedSci原创 MedSci原创

本项研究结果证实,麸质摄入与 CD 或 UC 的发病风险无关。此项研究结果令人欣慰,因为改变了人们越来越认为食用麸质会引发慢性胃肠道疾病的传统观念。

炎症性肠病(IBD)包括克罗恩病(CD)和溃疡性结肠炎(UC),是一类遗传易感宿主对环境和微生物刺激的免疫反应失调所致的胃肠道慢性炎症疾病。已知的遗传因素解释的IBD风险的占比不到14%,这突出了环境因素在疾病发展中的重要性。饮食被认为在炎症性肠病 (IBD) 的发生发展中发挥重要作用,但尚不清楚麸质摄入是否会导致 IBD的出现。本研究的目的是确定麸质摄入量与克罗恩病 (CD) 和溃疡性结肠炎 (UC) 风险之间的关系。

 

为此,研究人员对来自护士健康研究 (1986-2016)、护士健康研究 II (1991-2017) 和卫生专业人员随访研究 (1986-2016) 的 208,280 名美国参与者进行了一项前瞻性队列研究,所有受试者在入组时都没有IBD的诊断或存在乳糜泻,所有患者均完成了半定量食物频率问卷的调查。最后研究人员使用 Cox 比例风险模型根据随访期间累积平均能量调整膳食麸质摄入量的五分位数来估计 IBD 的发生风险。

 

研究人员在 5115265 人年的随访评估中记录了 337 例 CD 病例和 447 例 UC 病例的的发生。研究结果发现膳食麸质摄入与 IBD 发病风险无关。与谷蛋白摄入量最低五分之一的参与者相比,谷蛋白摄入量最高五分之一的参与者的调整后风险比和 95% CI 分别为 CD:1.16(95% CI,0.82-1.64;P = .41)和UC:1.04( 95% CI,0.75–1.44;P = .64)。调整麸质摄入的主要来源并没有实质性地改变IBD发病风险。
