BMJ:预测妊娠期糖尿病的模型的有效性怎样?

2016-08-30 fsy 译 MedSci原创

来自荷兰的研究人员进行了一项大型、前瞻性、多中心研究,该研究纳入了所有已发表的早期预测妊娠糖尿病风险模型,其目的是对已发表的早期预测妊娠糖尿病风险模型(包括适用于妊娠早期的预测因子)进行验证和比较。

来自荷兰的研究人员进行了一项大型、前瞻性、多中心研究,该研究纳入了所有已发表的早期预测妊娠糖尿病风险模型,其目的是对这些风险模型(包括适用于妊娠早期的预测因子)进行外部验证和比较。

该研究在荷兰的31个助产实践中心和6家医院进行。

在2012年12月和2014年1月期间,研究人员招募了怀孕初期(<14周)的女性,她们在最初的产前检查完成后参与了该研究。原本就患有糖尿病的女性被排除在外。

研究人员通过C统计评估来鉴别这些预测模型,通过标准曲线评估了校准。

共有3723名女性被纳入分析,其中181(4.9%)名女性在怀孕时发生妊娠期糖尿病。在该队列研究中共有12个预测模型可以进行验证。C统计范围从0.67到0.78。校准曲线显示,12个模型中的8个模型都进行了很好的校准。Ç统计最高的4个模型了包括了几乎所有如下的预测因子:孕妇年龄,孕妇体重指数,妊娠糖尿病史,以及糖尿病家族史。在未生育过的女性亚组中,预测模型都有类似的性能。决策曲线分析表明,使用这些模型中的任何一个模型,效果都会很好。

在这项外部验证研究中,大部分已发表的妊娠期糖尿病模型显示出可接受的鉴别和校准能力。在本次研究队列中,鉴别能力最高的四个模型在未生育过的孕妇亚组中也表现出良好的性能,并且这些模型很容易在临床实践中应用,因此未来研究值得进一步评估这些模型的临床影响。

妊娠期糖尿病是女性在妊娠时期最常见的疾病之一,肥胖会增加孕妇发生妊娠期糖尿病的风险。不同地区的发病率差异较大,旧金山综合医院的统计数据表明,2013年美国孕妇出现妊娠期糖尿病的风险为7-18%。该病对孕妇和胎儿都有影响。CDC指出,该病会导致胎儿的血糖过高并导致胎儿体重过重,增加产妇分娩意外的风险,同时孩子今后患肥胖和糖尿病的风险也增加。通过饮食和锻炼可以控制妊娠期糖尿病的发生,此外,服用药物也有

根据最新研究结果,美国学者指出,妊娠期孕妇糖尿病,或者妊娠期体重异常增加导致肥胖,跟宝宝的超重、肥胖有一定的关联,即便孩子出生的时候体重是正常的。 近期一项大数据调查,研究了妊娠期孕妇肥胖及妊娠期糖尿病,跟孩子童年肥胖的关联,他们发现,妊娠期孕妇糖尿病,可能提高孩子0-10岁阶段肥胖的风险,相关风险因子约为30%,而妊娠期体重异常增加,也会提高孩子的肥胖风险,相关风险约为15%。
