Assessment of the recommended gestational weight gain range in dichorionic diamniotic twin pregnancies and its association with perinatal outcomes
摘要
Abstract
Objective To investigate the appropriate range of gestational weight gain in pregnant women with dichorionic diamniotic(DCDA)twin pregnancies and its relationship with perinatal outcomes.Methods A total of 495 women with DCDA twin pregnancies delivering infants with birth weights 2 500 g between January 2017 and July 2024 at the Maternal and Child Health Hospital of Guangxi Zhuang Autonomous Region were enrolled.Firstly,according to the pre-pregnancy body mass index(BMI),it was divided into low body weight group,normal weight group,over-recombinant and obese group,and the percentiles of standardized pregnancy weight gain were calculated,and P25-P75 was used as the recommended range for weight gain during pregnancy.Secondly,according to the recommended range of appropriate weight gain,the research subjects were re-divided into underweight gain group,appropriate weight gain group,and excessive weight gain group,and the relationship between pregnancy weight gain and perinatal outcomes was analyzed.Results In this study,the appropriate range of pregnancy weight gain[M(P25-P75)]in the low weight group(51 cases),normal weight group(323 cases),over-recombinant(101 cases)and obese group(20 cases)was 19.0(16.6-21.4)kg,18.0(15.0-20.6)kg,15.8(12.7-18.8)kg and 14.7(11.7-19.9)kg,respectively.With the increase of pre-pregnancy BMI,the overall weight gain of twin pregnant women was less during pregnancy(H=23.643,P＜0.001).After regrouping according to the above recommended range,there were 124 cases in the insufficient weight gain group,244 cases in the appropriate weight gain group,and 127 cases in the excessive weight gain group.Compared with the underweight gain group and the appropriate weight gain group,the incidence of gestational diabetes mellitus and gestational hypertension was higher in the overweight gain group(x2 values were 12.849 and 7.421,P＜0.05,respectively).Compared with the appropriate weight gain group and the excessive weight gain group,the birth weight of newborns in the underweight gain group was lower and the proportion of newborns smaller than gestational age was higher(F/x2 values were 3.472 and 8.228,P＜0.05,respectively).Compared with the excessive weight gain group,the incidence of neonatal jaundice in the underweight gain group and the appropriate weight gain group was higher(x2=7.535,P＜0.05).Conclusion The higher the pre-pregnancy BMI,the less weight gain is suitable during pregnancy,and the higher the pre-pregnancy BMI,the less weight gain is suitable during pregnancy.Clinically,more attention should be paid to the gestational weight management of twin pregnancies to improve pregnancy outcomes and promote maternal and infant health.关键词
