Abstract:Objective: To explore the relationship between body mass index (BMI) in early pregnancy, weight gain during pregnancy and the incidence of gestational diabetes (GDM). Methods: A total of 140 pregnant women with 24-28 weeks gestation during pregnancy check-ups in our hospital from February 2019 to October 2020 were selected as the research subjects, and they were divided into GDM group and non-GDM group according to whether they had gestational diabetes. The BMI and weight gain during pregnancy of the two groups of pregnant women were recorded, and the relationship between them and the incidence of GDM was analyzed. Results: After OGTT screening, there were 33 pregnant women in the GDM group and 107 pregnant women in the non-GDM group. There is a statistically significant difference in the incidence of GDM with different BMIs (χ2=67.613, P<0.001),the incidence of GDM is highest when BMI ≥ 28.0kg/m2 (86.67%). There is a statistical difference in the incidence of different weight gains and GDM in the first trimester (χ2=7.634, P=0.022), and the incidence of weight gain> 5 kg GDM was the highest (36.73) %. BMI and weight gain are independent risk factors for GDM (P<0.05). BMI and weight gain were correlated with the incidence of GDM (r=-0.417, -0.212, P<0.05). Conclusion: Pre-pregnancy body mass index ≥ 28/m2 increases the risk of GDM in pregnant women. At the same time, weight gain in the first trimester> 5kg will increase the incidence of GDM. Therefore, management of pre-pregnancy BMI and weight gain during pregnancy can reduce the occurrence of gestational diabetes and reduce pregnancy complications. The occurrence of complications ensures the safety of mothers and babies.
