Eur Respir J:儿童期维生素A膳食摄入量、肺功能与哮喘发作的关系

2021-09-29 MedSci原创 MedSci原创

在儿童中期摄入更多预制维生素A,而非β-胡萝卜素,与更高的肺功能和更低的固定气流受限和哮喘发作风险相关。

关于维生素A膳食摄入量与儿童呼吸系统结局之间关联的纵向流行病学数据很少。

近日,呼吸疾病领域权威杂志Eur Respir J上发表了一篇研究文章,研究人员旨在调查童年中期摄入更多预制维生素A或维生素原β-胡萝卜素是否与更高的肺功能和青春期哮喘风险相关。

在对父母和儿童进行的Avon纵向研究中,研究人员通过食物频率问卷评估了7岁时预制维生素A和β-胡萝卜素等价物的膳食摄入量。在15.5岁时测量支气管扩张剂后1s用力呼气量(FEV1)、用力肺活量(FVC)和FVC25-75%时的用力呼气流量(FEF25-75)并转换为z分数。突发性哮喘定义为在11岁或14岁时诊断的哮喘病例。

在多变量调整模型中,较高的预制维生素A摄入量与较高的肺功能和较低的哮喘发病风险相关:比较摄入量的最高四分位数和最低四分位数,FEV1和FEF25-75的回归系数(95%置信区间)分别为0.21(0.05-0.38;趋势P=0.008)和0.18(0.03-0.32;趋势P=0.02);FEV1/FVC比值低于正常和哮喘的比值比(95%置信区间)分别为0.49(0.27-0.90,趋势P=0.04)和0.68(0.47-0.99;趋势P=0.07)。相反,没有证据表明与β-胡萝卜素有关。研究人员还发现了一些证据,证明BCMO1、NCOR2和CC16基因多态性可以改变预制维生素A摄入量与肺功能之间的关联。

由此可见,在儿童中期摄入更多预制维生素A,而非β-胡萝卜素,与更高的肺功能和更低的固定气流受限和哮喘发作风险相关。
