摘　　要：目的:分析足月单胎胎盘重量的影响因素。方法:回顾性收集2020年1-12月在本院规律产前检查并足月分娩的单胎产妇临床资料,根据胎盘重量分为过轻组、正常组、过重组,分析影响胎盘重量的相关因素。结果:纳入足月单胎产妇10 318例,过轻组605例(5.9%)、正常组8709例(84.4%)、过重组1004例(9.7%);胎盘重量孕37周(590±109g)低于其它孕周,孕41周(629±117g)高于其它孕周(均P<0.05)。产妇为高龄、经产妇、男婴、辅助生殖、孕前体重超重或肥胖、孕期增重过多、糖代谢异常和瘢痕子宫均是胎盘过重的影响因素,初产妇、女婴、孕期体重过低和孕期增重过少均是胎盘过轻的影响因素(均P<0.05)。结论:高龄、产次、胎儿性别、受孕方式、孕前体重指数、孕期增重、合并糖代谢异常及瘢痕子宫影响胎盘重量。Objective: To analyze the influencing factors of placental weight of women with full-term singleton pregnancy. Methods: A retrospective study was conducted to collect the clinical data of pregnant women with singleton pregnancy who had received regular health care and delivered in term from January to December 2020. According to the placental weight of the women, these women were divided into group A(women with low placental weight), group B(women with normal placental weight), and group C(women with over placental weight). The related factors affecting placental weight of the women were analyzed. Results: A total of 10318 women with full-term singleton pregnancy were in this study, which included 605(5.9%) women in group A, 8709(84.4%) women in group B, and 1004(9.7%) women in group C. The placental weight(590±109 g) of the women deliveried during 37 gestatioanl weeks was significantly lower than that(629±117g) of the women delivered during other gestational weeks, and the placental weight of the women delivered during 41 gestational weeks was significantly higher than that of the women delivered during other gestational weeks(P<0.05). Maternal advanced age, multipara, male infants, assisted reproduction, pre-pregnancy overweight or obesity, excessive weight gain during pregnancy, abnormal glucose metabolism, and scarred uterus of the women were all the influencing factors of their placenta overweight. Primipara, female infants, low pregnant weight, and low weight gain during pregnancy of the women were all the influencing factors of their placenta underweight(all P<0.05). Conclusion: The placental weight is affected by the advanced age, parity, fetal sex, mode of conception, pre-pregnancy body mass index, gestational weight gain, pregnancy with abnormal glucose metabolism, and scar uterus of the pregnant women.
