迄今为止,多项研究已经证明,在这场席卷全球的新冠肺炎(COVID-19)“大流行”中,老年人及身体状况不佳的人群往往是病毒侵扰的对象,而年轻人受影响的可能性更小。不过,最近《柳叶刀》上发布的一篇文章提出,那些肥胖的年轻人可能更容易被感染。

https://doi.org/10.1016/S0140-6736(20)31024-2

当3月份一批COVID-19患者前往美国约翰霍普金斯医院就诊时,该院的医护人员发现,就诊的患者往往更加肥胖。

于是,为了探究肥胖与COVID-19之间的关系,约翰霍普金斯大学心脏病学研究所医学教授卡斯David A Kass及其另外两名同事收集了来自于美国6个不同地区的重症监护病房的265位COVID-19患者的相关信息。

研究人员发现,年龄和BMI之间存在显著的负相关,其中入院的年轻个体更可能是肥胖人士,并且无性别差异。数据显示,这些患者的中位BMI为29.3,仅25%的患者BMI低于26.0,而25%的人BMI甚至超过了34.7。

265名COVID-19患者的BMI与年龄之间呈负相关

由于年轻患者存在心脏病、高血压等风险的几率更低,因此研究人员认为,肥胖本身可能就是一种让人们更易受病毒影响的风险因素,会增加患者住院或重症监护病房的可能性,并且病程可能会更加严重。

至于肥胖导致人们患COVID-19风险更高的原因,研究人员给出了两种解释。一方面,那些严重肥胖的患者(BMI≥35)体内存在过多的脂肪,尤其是在横膈膜下,这导致患者呼吸十分困难。另一方面,炎症也是一个重要风险因素。脂肪本身具有代谢活性,它产生相当数量的被称为细胞因子的促炎分子,由此在人体内引发了一场免疫大战,产生了低水平的背景炎症。

Kass认为,关于COVID-19值得进一步研究的另一个领域是ACE2蛋白在脂肪细胞中的作用。以往的研究表明,ACE2是新冠病毒进入人体的关键,但是脂肪细胞以相当高的水平表达ACE2,这可能会使肥胖患者在症状好转时更具传染性。

如果肥胖确实是COVID-19的风险因素,那么或许能够在一定程度上解释目前关于COVID-19确诊患者的数据。从世界范围来看,美国的肥胖患病率约为40%,意大利约为20%,而中国仅为6%。

这也提醒医护人员,应该对肥胖的患者给予更多的观察。肥胖人士也需要提高防护意识,以防感染病毒。
