Allergy:体重指数对花粉症、哮喘和肺功能的影响!

2017-07-05 xing.T MedSci原创

由此可见,这些结果支持增加的BMI与哮喘患病率升高和肺功能降低相关,但与花粉热或过敏生物标志物无关。

观察性研究表明体重指数(BMI)与哮喘呈正相关。然而,观察性数据容易产生混淆和反向因果关系。在孟德尔随机化中,遗传变异被当作不可混淆的暴露标志来评估因果效应。近日,过敏性疾病领域权威杂志Allergy上发表了一篇研究文章,研究人员评估了BMI对哮喘、花粉热、过敏、血清总免疫球蛋白E(IgE)、一秒用力呼气量(FEV1)和用力肺活量(FVC)的因果效应。

研究人员在观察性研究中招募了490497名参与者,在遗传分析中招募了162124名参与者。研究人员采用26个BMI相关的单核苷酸多态性(SNP)来建立了遗传风险评分(GRS)。在Meta分析中汇总了研究结果,分析结果以比值比(OR)或β估计值以及95%置信区间(CI)来表示。

研究人员发现每增加一个BMI相关的等位基因GRS与哮喘显著相关(OR为1.009; 95%CI为1.004-1.013),与与花粉热(OR为0.998; 95%CI为0.994-1.002)或过敏(OR为0.999; 95%CI为0.986-1.012)不相关。每增加一个BMI相关等位基因,GRS与FEV1:β为-0.0012(95%CI为-0.0019至-0.0006)和FVC:β为-0.0022(95%CI为-0.0031至-0.0014)的降低显著相关。通过工具变量分析估计的效果大小对于哮喘的OR为1.07(95%CI为1.03-1.10),BMI每增加1kg/m2,FEV1降低9ml(95%CI为2.0-15ml),FVC降低16ml(95%CI为7.0-24ml)。

由此可见,这些结果支持增加的BMI与哮喘患病率升高和肺功能降低相关,但与花粉热或过敏生物标志物无关。
