摘要

背景胎盘重量低与不良围产期结局有关。与成年孕妇相比,青少年孕妇的早产率、低出生体重和胎儿生长受限率较高。目标。比较青春期(≤19岁)和成年母亲(20-28岁)组的胎盘和新生儿重量。方法。一项前瞻性横断面研究是对妊娠≥37周分娩且没有母亲慢性疾病或产科并发症的初产妇进行的。青少年被分为两组(A1组,年龄<15岁;A2组,15-19岁),并与年龄为20-28岁的成年母亲对照组(B组)进行比较。A1组包括23个新生儿和18个胎盘,A2组包括28个新生儿和28个胎盘,B组包括27个新生儿和27个胎盘。使用配对样本的Student t检验比较两组之间的胎盘和新生儿重量。结果。A组新生儿和胎盘的平均重量(标准差(SD))显著低于B组:分别为3167.8克(359.6)对3404.0克(136.8)(p=0.0016)和573.7克(98.7)对651.0克(109.8)(p=0.0028)。A1组新生儿和胎盘的平均重量(SD)显著低于A2组:分别为2996.0 g(373.7)vs.3309.0 g(273.6)(p=0.0012)和513.0 g(94.9)vs.612.5 g(73.8)(p=0.0026)。结论。青少年组的胎盘和新生儿重量明显较低,而这种差异在年轻的青少年组中更为明显。

Comparison of newborn and placental weights between adolescent and adult women
Background. Low placental weight is associated with adverse perinatal outcomes. Adolescent pregnant women are associated with higher preterm labour, low birth weight and fetal growth restriction rates than adult pregnant women.  Objective. To compare placental and newborn weights between groups of adolescent (≤19 years old) and adult mothers (20 - 28 years old).  Methods. A prospective cross-sectional study was conducted with primiparous mothers who had their deliveries at ≥37 weeks’ gestation, and without maternal chronic disease or obstetrical intercurrence. Adolescents were divided into two groups (group A1, aged <15 years; group A2, 15 - 19 years), and the outcomes compared with a control group of adult mothers aged 20 - 28 years (group B). Group A1 included 23 newborns and 18 placentas, group A2 comprised 28 newborns and 28 placentas, and group B included 27 newborns and 27 placentas. The placental and newborn weights were compared between the groups using Student’s t -test for paired samples.  Results. The mean (standard deviation (SD)) weights of the newborns and placentas in group A were significantly lower than those in group B: 3167.8 g (359.6) v. 3404.0 g (136.8) ( p =0.0016) and 573.7 g (98.7) v. 651.0 g (109.8) ( p =0.0028), respectively. The mean (SD) newborn and placental weights in group A1 were significantly lower than those in group A2: 2996.0 g (373.7) v. 3309.0 g (273.6) ( p =0.0012) and 513.0 g (94.9) v. 612.5 g (73.8) ( p =0.0026), respectively.  Conclusion. The placental and newborn weights were significantly lower in the adolescent groups, and this difference was more pronounced in the younger of the adolescent groups.
