| 摘 要： | 目的 探讨孕期血红蛋白水平、孕前体质指数及孕期体重增长对妊娠结局的影响。 方法 回顾性分析2021年8月至2021年12月云南省第三人民医院分娩产妇的病历资料。根据孕期血红蛋白水平分为低Hb组（孕晚期血红蛋白 < 110 g/L）、中Hb组（孕晚期血红蛋白水平为110～130 g/L）、高Hb组（孕晚期血红蛋白水平≥130 g/L）；根据孕前体质指数分为3组:孕前BMI过低组（BMI < 18.5 kg/m2）、孕前BMI正常组（BMI为18.5～24.9 kg/m2）、孕前BMI过高组（BMI≥25 kg/m2）；根据妊娠期体重增加分为增重不足、增重正常、增重过度3组。对各组的妊娠结局进行比较。 结果 低Hb组、中Hb组、高Hb组的早产发生率，差异有统计学意义（P < 0.05）；孕前BMI过低组、孕前BMI正常组、孕前BMI过高组的新生儿出生体重、剖宫产、巨大儿、胎儿生长受限的发生率，差异有统计学意义（P < 0.05）；孕期增重不足组、孕期增重正常组、孕期增重过度组的新生儿体重、胎膜早破、巨大儿的发生率，差异有统计学意义（P < 0.05）。 结论 孕期血红蛋白、孕前BMI及孕期体重增长均对妊娠结局产生影响，合理地对其进行控制，从而减少不良妊娠结局的发生，促进母婴健康。

| 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. |
