Abstract

Objective. The increase of BMI before pregnancy and during pregnancy will lead to hypertensive disorder in pregnancy (HDP) and abnormal glycolipid metabolism, as well as increase the risk of neonatal weight abnormalities and adverse pregnancy outcome. This study retrospectively analyzed the clinical data of 358 women who were admitted to the obstetrics department of our hospital from January 2018 to July 2019. And the relationship between prepregnancy BMI, BMI increase during pregnancy and delivery methods, postpartum hemorrhage, neonatal weight, premature delivery, neonatal asphyxia, gestational diabetes mellitus (GDM), and hypertension during pregnancy (HDP) was observed and compared. The results show that both high BMI before pregnancy and excessive weight gain during pregnancy can lead to the incidence of abnormal birth weight and adverse birth outcome increase. Therefore, in order to reduce the incidence of neonatal weight abnormalities and adverse birth outcomes and to prevent the adverse effects during pregnancy and postpartum, clinically, obese women should be guided to eat according to reasonable diet and exercise to control their weight.

Highlights

Since pregnant women need to satisfy fetal growth and lactation, the maternal weight would increase with the pregnancy process going on. erefore, weight measurement is the necessary part in pregnancy tests [1]
Body mass index (BMI) and weight gain during pregnancy are used for measuring maternal nutritional conditions and fetal growth [4]
The increase of body mass index (BMI) before pregnancy and during pregnancy increases significantly, which results in an increased incidence of hypertensive disorder in pregnancy (HDP) and abnormal glucose and lipid metabolism and affects the growth and gestational age of the fetus [5,6,7]. e purpose of the study is to analyze the relationship between BMI of pregnant women before pregnancy, weight gain during pregnancy, and neonatal weight and delivery outcome to provide scientific reference for clinical perinatal healthcare of the parturient

Summary

Introduction

Since pregnant women need to satisfy fetal growth and lactation, the maternal weight would increase with the pregnancy process going on. erefore, weight measurement is the necessary part in pregnancy tests [1]. Since pregnant women need to satisfy fetal growth and lactation, the maternal weight would increase with the pregnancy process going on. Body mass index (BMI) and weight gain during pregnancy are used for measuring maternal nutritional conditions and fetal growth [4]. E exclusion criteria were as follows: (i) multiple pregnancy, (ii) placenta previa, (iii) placental abruption, (iv) cesarean delivery due to society reasons and lack of information cases, and (v) women with advanced maternal age. Height (m) and weight (kg) of pregnant women were, respectively, applied to calculate BMI before pregnancy and delivery. Gestational diabetes mellitus (GDM), hypertensive disorders of pregnancy (HDP), delivery modes, postpartum hemorrhage, neonatal weight, asphyxia neonatorum, and other situations were recorded. Measurement data were expressed as mean ± standard deviation (x ± s), an independent sample t-test was used for comparison between groups, count data were expressed as n (%), and chi-square (χ2) test was performed. e difference was statistically significant when P < 0.05
