Risk factors for gestational diabetes mellitus in advanced maternal age at the early stage of pregnancy / 中国糖尿病杂志

ABSTRACT

Objective To explore the risk factors for gestational diabetes mellitus (GDM ) in advanced maternal age (AMA) at the early stage of pregnancy .Methods A total of 1200 subjects with AMA were enrolled in this study as AMA group from Jun 2016 to Jul 2017 in Beijing Obstetrics and Gynecology Hospital of Capital Medical University .Each group was further divided according to OGTT results:GDM group and NGDM group .The risk factors of GDM were analyzed .Results The prevalence of GDM was 24.17%(290/1200) .The history of type 2 diabetes in first-degree relatives,pre-pregnancy BMI,TG,FPG,FIns,and HOMA-IR were significantly different in the two groups (P＜0.05) .Pearson correlation analysis showed that GDM was positively correlated with the history of type 2 diabetes in first-degree relatives,pre-pregnancy BMI,TG,FPG,FIns and HOMA-IR (r= 0.519,0.413,0.451, 0.625,0.531,0.214,P＜ 0.05) .Multivariate logistic regression analysis showed that history of type 2 diabetes in first-degree relatives,pre-pregnancy BMI,TG,FPG,FIns and HOMA-IR were independent risk factors for GDM (OR=1.635,1.133,2.153,2.418,1.390,1.901,P＜0.05) .Conclusion During early pregnancy in subjects with AMA,TG,FPG,FIns,history of type 2 diabetes in first-degree relatives,pre-pregnancy BMI were independent risk factors for GDM .
