Abstract

Abstract

Objective To investigate the effects of hemoglobin level during pregnancy, pre-pregnancy body mass index and weight gain during pregnancy on pregnancy outcomes. Methods Retrospective research was used to analyze the medical records of delivery women in Yunnan Third People’s Hospital from August 2021 to December 2021. According to the hemoglobin level during pregnancy, they were divided into low hemoglobin group, middle hemoglobin group and high hemoglobin group. According to pre-pregnancy body mass index, they were divided into 3 groups: low pre-pregnancy BMI group, normal BMI group, and pre-pregnancy high BMI group. According to weight gains, they were divided into three groups: insufficient weight gain, normal weight gain, and excessive weight gain. The pregnancy outcomes of each group were compared. Results There were statistical differences in the incidence of preterm birth among the low hemoglobin group, the middle hemoglobin group and the high hemoglobin group （P < 0.05）. There were statistical differences in the incidences of uterine birth, macrosomia, and fetal growth restriction （P < 0.05）. There was a statistical difference in the incidence of macrosomia （P < 0.05）. Conclusion Pregnancy hemoglobin, pre-pregnancy BMI and gestational weight gain all have an impact on pregnancy outcomes, and reasonable control of them can reduce the occurrence of adverse pregnancy outcomes and promote maternal and infant health.
