JCEM:孕妇血糖和子女血管结构和功能之间的关系

2020-04-22 MedSci原创 MedSci原创

在没有糖尿病的母亲中,妊娠期间血糖升高与6岁儿童血管轻度结构和功能性变化有关。这些结果支持在没有糖尿病或经诊断为妊娠糖尿病的情况下,也有必要在妊娠期间监测孕妇血糖。

对于没有糖尿病的女性,妊娠期间高血糖对后代心血管结构和功能的影响知之甚少。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,研究人员旨在调查孕妇血糖与他们孩子心血管风险标志物之间的关系。

在妊娠26周左右,孕妇进行了75g口服葡萄糖耐量测试,并测量了空腹血糖(FPG)和餐后2小时血浆血糖(2小时PPPG)浓度。妊娠糖尿病(GDM)是根据WHO 1999诊断标准定义的。在子代6岁时,研究人员测量了孩子的颈动脉内膜中层厚度(cIMT)、颈动脉股动脉脉搏波速度(cfPWV)、主动脉扩张指数(AIx)和血压(BP),并使用多元线性和Logistic回归分析了妊娠期孕妇血糖与儿童心血管风险标志物之间的关系。

研究人员分析了479对母子。较高的母亲FPG与男孩较高的cIMT相关,与子女较高的cfPWV相关(校正后的β[CI 95%],cIMT每增加10mm为0.08 [0.02-0.15],cfPWV为0.36 m/s [0.01-0.70]) 。较高的2小时PPPG与较高的cfPWV和AIx相关。GDM与更高的AIx相关。孕妇血糖与其子女血压之间未发现关联。

由此可见,在没有糖尿病的母亲中,妊娠期间血糖升高与6岁儿童血管轻度结构和功能性变化有关。这些结果支持在没有糖尿病或经诊断为妊娠糖尿病的情况下,也有必要在妊娠期间监测孕妇血糖。
