A retrospective cohort study was performed in a tertiary centre to determine if teenage nulliparas (aged alpha19 years, study group) had higher incidences of instrumental and Caesarean deliveries compared with nulliparas aged 20-34 years (control group) selected from the first women in the birth registry who delivered after each study case and satisfying the criteria for controls. The hospital records of the study and control cases were retrieved for review. Comparison was made in the maternal demographics, major antenatal complications, outcome of labour, mode of delivery, and perinatal outcome. In the study group, maternal height was similar but the body mass index was lower. Although the mean birthweight was lower and the incidences of preterm labour and small-for-gestational-age infants higher, there were also increased incidences of large-for-gestational-age and macrosomic infants. While there was no difference in the types of labour, there were fewer Caesarean and instrumental deliveries, a finding that persisted even after excluding the preterm deliveries. Lastly, teenage mothers aged <17 years had similar outcomes to those aged 17-19 years. These results indicated that teenage mothers had better obstetric outcomes, despite the higher incidence of preterm labour, and that young adolescents (<17 years) performed as well as their older peers.
在一家三级医疗中心进行了一项回顾性队列研究，以确定青少年未生育女性（年龄小于19岁，研究组）与从出生登记册中在每个研究病例之后分娩且符合对照标准的20 - 34岁未生育女性（对照组）相比，器械助产和剖宫产的发生率是否更高。检索了研究组和对照组病例的医院记录进行审查。对产妇人口统计学特征、主要产前并发症、分娩结局、分娩方式和围产期结局进行了比较。在研究组中，产妇身高相似，但体重指数较低。尽管平均出生体重较低，早产和小于胎龄儿的发生率较高，但大于胎龄儿和巨大儿的发生率也有所增加。虽然分娩类型没有差异，但剖宫产和器械助产的次数较少，即使排除早产病例后这一发现仍然存在。最后，年龄小于17岁的青少年母亲与17 - 19岁的母亲结局相似。这些结果表明，尽管早产发生率较高，但青少年母亲的产科结局更好，而且年龄较小的青少年（小于17岁）与年龄较大的同龄人表现相当。
