JCEM:CT得到的体脂分布与心血管事件发生有何关系?

2017-08-17 xing.T MedSci原创

在一个多民族队列中,内脏脂肪,而不是皮下脂肪,与心血管疾病的风险显著相关。这些数据支持进行有效的生活方式改变策略来预防和减少内脏脂肪。

内脏脂肪已被证明与心脏代谢风险增加相关,但皮下脂肪的作用尚不清楚,并且来自于不同人群的证据较为缺乏。近日,内分泌和代谢性疾病领域权威杂志Journal of Clinical Endocrinology & Metabolism上发表了一篇研究文章,研究人员假设内脏脂肪,而不是皮下脂肪,与心血管疾病发生以及全因死亡率独立相关。

研究人员对动脉粥样硬化多种族研究中的1910名受试者采用计算机断层扫描(CT)进行了腹部脂肪测量,平均随访9.3年,采用多变量Cox比例风险模型探讨内脏和皮下脂肪与心血管疾病和死亡率之间的相关性。研究人员检测了相互作用,并对内脏脂肪的亚组和缺失值进行敏感性分析。

参与者的平均年龄为65岁,内脏脂肪为150cm2,皮下脂肪为263cm2,而50%为女性,21%为非洲裔美国人,13%为亚裔和26%为西班牙裔。在调整了年龄、性别、种族/民族、收入、受教育程度、吸烟和皮下脂肪的模型中,研究人员发现内脏脂肪与心血管疾病之间存在显著的正相关关系,而不是与死亡率。合并心血管疾病的关联可能由冠心病事件所驱动(组2:HR=2.43(1.38-4.28)和组3:HR=3(1.66-5.43))。此外,研究人员发现皮下脂肪与心血管疾病或死亡率之间并无显著相关性。年龄、性别、种族间也没有显著的交互作用。

在一个多民族队列中,内脏脂肪,而不是皮下脂肪,与心血管疾病的风险显著相关。这些数据支持进行有效的生活方式改变策略来预防和减少内脏脂肪。
