Relationship between pre-pregnant body mass index and pregnancy growth with maternal and neonatal outcomes / 重庆医学

ABSTRACT

Objective To explore the effects of the pre-pregnant body mass index(BMI) and the pregnancy growth on the mater-nal and neonatal outcomes .Methods 250 pregnant women with the built file ,regular antenatal inspection and hospital delivery in our hospital during 2011 were selected and divided into the emaciation group ,the appropriate group and the obesity group according to the pre-pregnant BMI .The occurrence rates of cesarean section ,fetal macrosomia ,low birth weight ,postpartum hemorrhage ,ges-tational diabetes ,gestational hypertension disease ,fetal distress ,neonatal asphyxia and puerperal infection were compared among the various groups .In addition ,according to the different growth amplitudes of pregnancy BMI ,the pregnant women were re-divided in-to 3 groups(weight gain insufficient group ,weight gain appropriate group and weight gain overmuch group ) and the different ma-ternal and neonatal outcomes were compared .Results The occurrence rates of cesarean section ,macrosomia ,gestational diabetes and gestational hypertension disease in the obesity group were significantly higher than those in the emaciation group and the appro-priate group(P<0 .05) ,while the occurrence rate of the low birth weight in the emaciation group was significantly higher than that of the appropriate group and the obesity group(P<0 .05);the occurrence rates of cesarean section ,macrosomia ,gestational diabetes and gestational hypertension disease in the weight gain overmuch group were significantly higher than those in the weight gain in-sufficient group and the weight gain appropriate group(P<0 .05) ,while the occurrence rate of low birth weight in the weight gain insufficient group was significantly higher than that of the weight gain appropriate group and the weight gain overmuch group (P<0 .05) .Conclusion The maternal and neonatal outcomes in the pregnant women with pre-pregnant BMI exceeding the standard and pregnant BMI overmuch growth are very worrying .The growth of pre-pregnant BMI and pregnant BMI is one of the important indi-cators for monitoring the maternal and neonatal complications .
