Relationship Between Obstetric Complications, Delivery Outcome And Pregnancy Weight Of Pregnant Women Who Have Different Pre-pregnancy Weight

Objective:To understand the relationship between obstetric complication delivery outcome and different pre-pregnancy weight and pregnancy weight gain, to approach the appropriate range of the pre-pregnancy weight and pregnancy weight gain, in order to provide the scientific basis of clinical pregnancy care.Methods:747cases of primipara were divided into four groups according to pre-pregnancy body mass index:thin group(BIM<18,7),normal weight group (normal group18,7<BMI<23), over weight group (23<BMI<25), obese group(BMI≥25),were divided into three groups according to different ranges of body weight increase during pregnancy (△W<15Kg.15Kg≤△W<20Kg、△W≥20Kg. To record pregnant women’s pre-pregnancy weight and measured height a month before delivery, the pre-hospital childbirth weight, pregnancy complications, neonatal birth weight, macrosomia, neonatal Apgar’s score and perinatal concurrent syndrome, calculation of pre-pregnancy body mass index(BMI), weight gain during pregnancy. To compare the relationship of obstetric complications and delivery outcome between different groups.Result:1)The rate of birth Process block and uterine-incision delivery of thin group, normal group, overweight group and obese group had statistically significant different(P<0.05)。2))Pregnancy-induced hypertension, gestational diabetes, neonatal bodyweight, fetal macrosomia and weight gain during Pregnancy were compared statistically significant difference (P<0.05) between thin group, normal group, overweight and obesity, with pre-Pregnancy weight gain, the incidence of hypertensive, gestational diabetes, and fetal macrosomia disorders in Pregnancy gradually increased, a gradual increase in birth weight, Pregnancy weight gain, reduced gradually. Overweight and Obesity, the incidence of Pregnancy-induced hypertension group and gestational diabete group were significantly higher than thin group, normal group, overweight and obesity were similar.3))Fetal distress, neonatal jaundice, neonatal asphyxia and Postpartum hemorrhage had no statistical significance (P>0.05) between thin group, normal group, overweight and obesity.4) Pregnancy weight gain<15kg,15-20kg,≥20kg,the incidence of Pregnancy induced hypertension and fetal macrosomia between the two groups were statistically significant different(P<0.05), birth weight in each group comparison were statistically significant different (P<0.01).Conclusion:Properly controlling Pre-Pregnancy weight and Pregnancy weight gain in a certain range can significantly reduce the occurrence of Pregnancy-induced hypertension, gestational diabetes, Production Process block, neonatal body weight, fetal maerosornla, cesarean section rate and improve the health of mother and child. This study suggests that the best weightrange:18.5<Pre-Pregnancy BMI<23, Pregnancy weight gain<15kg.
