Am J Gastroenterol:不管代谢正常与否,只要你胖,NAFLD的风险就增加了

2016-05-21 Seven L MedSci原创

肥胖个体的非肥胖相关的代谢异常称为新陈代谢健康型肥胖(MHO),其与非酒精性脂肪性肝病(NAFLD)的联系很大程度上是未知的,因此研究者对一个大型的代谢健康的男女队列进行了研究,探究BMI变化和NAFLD发展之间的关系。该队列含有77,425名非NAFLD的基线代谢异常的参与者,每年或两年随访一次,平均4.5年。新陈代谢健康定义为没有任何代谢综合征,以及稳态模型胰岛素抵抗指数<2.5。有没有脂肪肝

肥胖个体的非肥胖相关的代谢异常称为新陈代谢健康型肥胖(MHO),其与非酒精性脂肪性肝病(NAFLD)的联系很大程度上是未知的,因此研究者对一个大型的代谢健康的男女队列进行了研究,探究BMI变化和NAFLD发展之间的关系。

该队列含有77,425名非NAFLD的基线代谢异常的参与者,每年或两年随访一次,平均4.5年。新陈代谢健康定义为没有任何代谢综合征,以及稳态模型胰岛素抵抗指数<2.5。有没有脂肪肝通过超声来确认。

在随访的348,193.5人年中,10,340名参与者患上了NAFLD(发生率29.7/1000人年)。多变量校正后,与正常体重参与者相比,超重和肥胖的NAFLD风险分别为2.15 (2.06–2.26)和3.55 (3.37–3.74)。剂量反应分析显示,基线BMI的增加与NAFLD发生率间几乎呈线性关系,并且不存在零风险阈值门槛。不管男女,两者间的关系均存在,女性的关联更强(交互P <0.001),并且对包括低炎症状态的参与者在内的临床相关亚组评估中,这是显而易见的。

对严格定义代谢健康的男性和女性的研究表明,超重和肥胖与NAFLD发病率增加逐渐相关,提示只要拥有肥胖表型,无论代谢是否正常,均会导致NAFLD风险的增加。
