“…Pregnant adolescents have to balance multiple energetic demands, including the growth and development of their own tissues, but also that of their developing infant. Changes in HPAA function may mediate changes in energy allocation strategies and energy devoted to pregnancy or maternal growth (Rowlands et al., 2021). For example, maternal growth occurs in about 50% of adolescent pregnancies but may come at the cost of fetal growth (Scholl et al., 1990).…”

Maternal prenatal psychosocial stress is associated with adverse hypothalamicpituitary-adrenal axis (HPAA) function among infants. Although the biological mechanisms influencing this process remain unknown, altered DNA methylation is considered to be one potential mechanism. We investigated associations between maternal prenatal psychological distress, infant salivary DNA methylation, and stress physiology at 12 months. Mother's distress was measured via depression and anxiety in early and late pregnancy in a cohort of 80 pregnant adolescents. Maternal hair cortisol was collected during pregnancy. Saliva samples were collected from infants at 12 months to quantify DNA methylation of three stress-related genes (FKBP5, NR3C1, OXTR) (n = 62) and diurnal cortisol (n = 29). Multivariable linear regression was used to test for associations between prenatal psychological distress, and infant DNA methylation and cortisol. Hair cortisol concentrations in late pregnancy were negatively associated with two sites of FKBP5 (site 1:

“…Inadequate sexual education often leads to adolescents engaging in risky sexual behaviors, such as unprotected intercourse, which can result in unintended pregnancies and exposure to sexually transmitted infections (STIs) [16].

Introduction: Adolescent pregnancy remains a contentious issue despite improvements in quality of life and increased access to sexual education. The average age of first pregnancy has shifted due to financial instability among young people, leading to delayed pregnancies until financial stability is achieved. Teenage mothers face social stigma, and early sexual initiation not only increases the risk of pregnancy but also sexually transmitted infections (STIs). Often, adolescent pregnancies are unwanted, resulting in delayed medical consultation due to fear or ignorance. Aim of the Study: This study aims to investigate the medical and social implications of adolescent pregnancy, emphasizing the importance of early sexual education and comprehensive healthcare support. Description of the State of Knowledge: Adolescent pregnancy, defined as pregnancy between ages 10 and 19, is a global concern with millions of cases annually. It poses significant health risks, including premature birth, low birth weight, and intrauterine growth restriction. Socially, it affects educational attainment and financial stability, with adolescents from lower socioeconomic backgrounds facing greater challenges. Early sexual initiation and risky sexual behaviors further compound the issue, increasing the risk of STIs. Lack of comprehensive sexual education exacerbates these risks, highlighting the need for multidisciplinary support from healthcare professionals. Conclusions: Adolescent pregnancy requires a holistic approach encompassing medical, social, and legal dimensions. Effective sexual education programs, involving gynecologists, pediatricians, and educators, are essential for prevention. Legal frameworks must protect adolescents and address issues of consent and sexual health. Additionally, access to comprehensive healthcare services, including prenatal care and contraception, is crucial for mitigating the adverse effects of adolescent pregnancy on both individuals and society.

“…Полученные результаты перекликаются с имеющимися мировыми данными [27], подкрепляют убеждение в том, что эффективное сдерживание подростковой беременности следует рассматривать как ключевой приоритет программы общественного здравоохранения и социальных изменений: необходимо начинать с момента зачатия, что требует создания стабильной и безопасной среды, а именно -улучшения экономического и социального равенства. Подростковая беременность усугубляет и увековечивает социальное неравенство внутри поколений и между ними.…”

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.
