Abstract:
Objective To investigate the correlation between body mass index and the increase in body mass during pregnancy and adverse pregnancy outcomes in elderly pregnant women. Methods The clinical data was collected from 1,374 pregnant women who underwent regular prenatal care checkups and delivered a child at Jiangsu Maternity and Child Health Hospital from January 1, 2020 to May 1, 2020. According to the age of pregnant women, pre-pregnancy body mass index (BMI), and gestational weight gain (GWG), the subjects were divided into different groups. The incidence of adverse pregnancy outcomes between groups was compared, and the correlation between pregnant women's age, pre-pregnancy BMI and GWG and adverse pregnancy outcomes was analyzed. Results Compared with the non-advanced age group, the elderly group had an increase in the incidence rate of gestational diabetes (GDM) (38.66% VS 19.54%), the incidence rate of large for gestational age (LGA) (LGA) (19.75% VS 14.43%), and the cesarean section rate (55.46% VS) 34.77%), and the differences between the groups were statistically significant (t=40.773, 4.270, 35.630, P=0.001, 0.039, 0.001). There were no significant differences between the non-advanced age group and the elder group in the incidence of pregnancy-induced hypertension (PIH) (10.92% VS 8.63%), the incidence of small for gestational age (2.52% VS 2.90%), and the incidence of neonatal asphyxia ( 2.10% VS 1.23%) (t=1.265, 0.105, 1.088, P=0.261, 0.746, 0.297). ). The incidence of GDM in overweight and obese elderly pregnant women was higher than that in underweight and normal pregnant women. The incidence of GDM in the elderly pregnant women with less GWG and excessive GWG was higher than that in the normal group (P<0.05). Conclusion The pre-pregnancy body mass index and the gain in body mass during pregnancy are related to the occurrence of adverse pregnancy outcomes. It is necessary to strengthen the monitoring and management of pre-pregnancy body mass index and pregnancy body quality in elderly pregnant women.
