CIRC RES:长期超重与成人左心室肥厚通过成人体型和血压联系起来

这些结果表明增加的儿童体重指数对成人心脏结构的亚临床改变存在长期不良影响,早期生活中超重和成年LVH之间通过后期生活中超重和和升高的血压联系在一起。

儿童肥胖与后期的心脏结构相关,但很少有人知道关于儿童体重会在何种程度上通过成人体型和血压来影响成人左心室结构。近日,心血管领域权威杂志Circulation Research上发表了一篇研究文章,研究人员旨在定量测定成年体重和血压的介导效应对儿童体重指数与成人左心室肥厚(LVH)之间相关性的影响。

在这项纵向研究中包括了710名成人,年龄在26岁至48岁之间,在儿童时期检查体重指数和测量血压4次或更多,在成年期进行了2次或以上的体重指数和血压测量,平均随访期为28年。

在调整了年龄、种族和性别,成人体重指数对儿童时期体重指数与成人左心室重量指数(LVMI)之间的相关性存在显著的介导作用(76.4%,P<0.01)。成人收缩压(SBP,15.2%)的介导效应、长期负担(12.1%)和SBP的升高趋势(7.9%)都具有统计学意义(P<0.01)。此外,这些介导因素也对儿童体重指数与成人左心室肥厚、离心和向心性肥厚之间的相关性存在显著的介导效应。重要的是,成人体重指数的介导效应均显著强于成人SBP对LVMI、LVH和左心室重构(P<0.01)。此外,SBP对向心性肥厚的介导效应显著强于离心性肥厚(P<0.01)。

这些结果表明增加的儿童体重指数对成人心脏结构的亚临床改变存在长期不良影响,早期生活中超重和成年LVH之间通过后期生活中超重和和升高的血压联系在一起。
