Relationship between Pre-pregnancy BMI,Weight Gain during Pregnancy and Perinatal Maternal and Infant Outcomes in Twin Pregnant Women
Objective:To analyze the relationship between pre-pregnancy body mass index(BMI),weight gain during pregnancy and perinatal maternal and infant outcomes in twin pregnant women.Method:The clinical data of 600 pregnant women with twin pregnancy who admitted to Liangzhou Hospital in Wuwei City from May 2018 to May 2022 were retrospectively collected,they were divided into low weight group(n=278),normal weight group(n=286),overweight group(n=28)and obesity group(n=8)according to the pre-pregnancy BMI;they were divided into insufficient weight gain group(n=204),appropriate weight gain group(n=256)and excessive weight gain group(n=140)according to the weight gain during pregnancy[BMI difference(ΔBMI)].The relationship between pre-pregnancy BMI,weight gain during pregnancy and perinatal maternal and infant outcomes were explored.Result:The proportion of insufficient weight gain during pregnancy in the low weight group was higher than that in the overweight group,the proportion of excessive weight gain during pregnancy was lower than that in the overweight group,and the proportion of insufficient weight gain during pregnancy in the normal weight group was higher than that in the overweight group,the differences were statistically significant(P<0.05).The incidence of postpartum hemorrhage,gestational hypertension,gestational diabetes,placental abruption,fetal distress,macrosomia and neonatal birth weight in the overweight group and obesity group were higher than those in low weight group and normal weight group,and the incidence of gestational hypertension,gestational diabetes,postpartum hemorrhage,fetal distress of low weight group were higher than those in the normal weight group,and the neonatal birth weight was lower than that in the normal weight group,the differences were statistically significant(P<0.05).The incidence of gestational hypertension,gestational diabetes,placental abruption,postpartum hemorrhage,fetal distress,macrosomia and neonatal birth weight in the excessive weight gain group were higher than those in the appropriate weight gain group and the insufficient weight gain group,the incidence of gestational hypertension,gestational diabetes,postpartum hemorrhage and fetal distress in the insufficient weight gain group were higher than those in the appropriate weight gain group,the neonatal birth weight was significantly lower than that in the appropriate weight gain group,and the differences were statistically significant(P<0.05).Conclusion:Abnormal pre-pregnancy BMI levels and abnormal BMI changes during pregnancy in twin pregnant women can lead to a higher risk of adverse pregnancy outcomes,therefore,more attention should be paid to the weight of twin pregnant women in clinical practice,effective measures can be taken to intervene and manage their pre-pregnancy weight and weight changes during pregnancy,so as to reduce the risk of adverse pregnancy outcomes.
