Structure of reproductive losses of adolescent girls and women of reproductive age in the Tyumen

Introduction. The reproductive experience of women 18–44 years of age is quantitatively superior to adolescent girls. The structure of reproductive losses of adolescents, its identity or difference in comparison with women of reproductive age is extremely unexplored.Aim. To compare the structure of reproductive losses of adolescents and women of reproductive age on the example of the Tyumen region.Materials and methods.A retro-prospective analytical study carried out. Study period – 2016–2021. Adolescent girls and women of reproductive age with completed pregnancies included.Results and discussion. In the Tyumen region, the frequency of reproductive losses approaches childbirth (42.83% and 57.17%), mainly represented by medical abortion (59.98%). The proportion of completed pregnancies among adolescent girls (1.14%) is  inferior to women of reproductive age (98.86%). Adolescent girls are characterized by the completion of pregnancy by childbirth (OR = 1.68), a high frequency of medical abortion (OR = 1.71). Reproductive losses up to 12 weeks distinguish completed pregnancies in women of reproductive age (OR = 1.68); unsuccessful abortion attempt, criminal and unspecified types of abortion before 12 weeks and other abnormal products of conception after 12 weeks are their exclusive markers. The pregnancy outcome is associated with age: with adolescents – medical abortion before (OR = 1.71) and after 12 weeks (OR = 2.01); with reproductive age – other abnormal products of conception (OR = 1.64) and ectopic pregnancy (OR = 6.15). Reproductive losses are associated with gestational age before/after 12 weeks: with adolescents – spontaneous abortion after 12 weeks (OR = 2.55); with reproductive age – other types of abortion (OR = 20.37), medical abortion (OR = 1.93), other abnormal products of conception (OR = 1.89) before 12 weeks and spontaneous abortion (OR = 5.42) after 12 weeks.Conclusion.In the Tyumen region, reproductive losses in frequency compete with childbirth. Augmented the concept of the abortion-contraceptive behavior of modern society based on the association of medical abortion with adolescent girls that we have identified. The structure of reproductive losses is associated with a woman’s age period and gestational age.
