Predictive Value of Pre-pregnancy Body Mass Index Combined with Weight Gain During Pregnancy on Pregnancy Outcome in Elderly Pregnant Women
Objective To study the predictive value of pre-pregnancy body mass index combined with weight gain during pregnancy on pregnancy outcome in elderly pregnant women.Methods A total of 62 elderly pregnant women who underwent prenatal examination in Wuyuan County Maternal and Child Health Hospital from June 2022 to May 2024 were selected as the research objects.Based on the"Recommended Value Standard for Weight Gain of Pregnant Women"issued by the National Health Commission in 2022,they were divided into three groups according to the pre-pregnancy body mass index,namely,low body mass index group,normal body mass index group,overweight and obesity group.The incidence of gestational diabetes mellitus(GDM)and the incidence of adverse pregnancy outcomes were compared among the three groups.The correlation between pre-pregnancy body mass index,weight gain during pregnancy and adverse pregnancy outcomes in elderly pregnant women was analyzed.Results The incidence of GDM in the low body mass index group and normal body mass index group was lower than that in the overweight and obesity group(P<0.05).The more weight gain during pregnancy,the higher the incidence of GDM(P<0.05).The incidence of adverse pregnancy outcomes in the low body mass index group and normal body mass index group was lower than that in the overweight and obesity group(P<0.05).The more weight gain during pregnancy,the higher the incidence of adverse pregnancy outcomes(P<0.05).Pearson correlation showed that pre-pregnancy body mass index and weight gain during pregnancy were positively correlated with adverse pregnancy outcomes(P<0.05).Conclusion Elderly pregnant women are high-risk pregnancies.Excessive weight gain during pregnancy or excessive increase in pre-pregnancy body mass index will increase the incidence of adverse pregnancy outcomes.Clinically,attention should be paid to the management of weight gain during pregnancy in elderly pregnant women.Balanced nutrition,so that the weight gain of elderly pregnant women is controlled within a reasonable range,thereby minimizing the occurrence of adverse pregnancy outcomes.
