Diabetologia:子宫内营养过剩对子代肥胖的持续影响:探索儿童围产期结局(EPOCH)研究

2019-12-24 MedSci MedSci原创

之前的研究表明,妊娠期糖尿病(GDM)的宫内暴露增加了青春期前青少年肥胖的选定标志物。在目前的研究中,研究人员检查了这些关联在青春期,并探讨否随着参与者青春期过渡这种关联逐渐增强。

之前的研究表明,妊娠期糖尿病(GDM)的宫内暴露增加了青春期前青少年肥胖的选定标志物。在目前的研究中,研究人员检查了这些关联在青春期,并探讨否随着参与者青春期过渡这种关联逐渐增强。

在两次研究访问中收集了参加科罗拉多州儿童纵向探索围产期结局(EPOCH)研究的597名个体(505名未暴露者,92名暴露者)的数据,这些参与者平均年龄为10.4岁和16.7岁。 肥胖测量包括BMI,腰围/身高比以及内脏和皮下脂肪组织(由MRI确定)。 使用单独的一般线性混合模型评估母体GDM暴露与每个肥胖结局之间的纵向关系。 我们通过在模型中加入暴露和年龄之间的相互作用项来测试效果是否随时间变化,以及是否通过产后行为来解释这种关联。

与未暴露的参与者相比,那些暴露于孕产妇GDM BMI较高(β= 1.28;95% CI 0.35, 2.21;p < 0.007),腰围/身高比例(β= 0.03;95% CI 0.01, 0.04;p = 0.0004),内脏脂肪组织(β= 4.81;95% CI 1.08, 8.54;p = 0.01)和皮下脂肪组织(β= 35.15;95% CI 12.43 57.87;p < 0.003)。这些差异的大小并没有随着时间的推移而改变,这些关联似乎也没有被出生后的行为所解释。

我们的数据提供了进一步的证据,证明子宫内暴露于母体GDM与子代肥胖增加有关,这种影响在生命早期出现,并贯穿整个青春期。因此,预防宫内暴露于母亲GDM儿童肥胖应重点针对产前或生命早期。
