According to the article, pregnancy in adolescence is associated with a high risk of developing adverse outcomes both during pregnancy and childbirth in the later period. The purpose of our study was to identify the features of pregnancy and childbirth, the postpartum period in young mothers. Materials and methods. A retrospective analysis of the birth history of 299 maternity hospitals was performed. The research material was archived data from the Regional perinatal center No. 3 in Turkestan (Kazakhstan). The main (1) group was formed by 199 maternity women under 19 years of age (2019). The control (2) group was formed by 100 maternity women aged 20 to 30 years, whose sexual life began after the age of 18. Results. The age of the surveyed women in group 1 ranges from 15 to 19 years, averaging ~16.9 years. 17-year-old girls predominated (66.7%). The average age of women in group 2 was ~25.8 years. Adolescent pregnancy is a risk factor for adverse child outcomes, such as premature birth, low birth weight, fetal growth retardation, neonatal and infant mortality. In the adolescent pregnancy and delivery group, preterm birth occurred in 35 cases, which accounted for 6.8% of the total preterm birth population for 2019, but in the adolescent birth group it was 17.5%. Of the 199 births in 2 were multiple births (1%), 197 live births, the percentage of live births among adolescents was 98%, respectively, the stillbirth rate was 2% (4 cases). Conclusion: the frequency of teenage pregnancy in the dynamics of years does not tend to decrease, among young mothers only every 6 received pre-pregnancy training, and every 5 was re-pregnant and among re-pregnant women under 19 years.
