This article presents the results of a study on psychoemotional stress observed in a northern environment, an important factor contributing to the development of abnormalities during pregnancy and leading to a risk of miscarriage in first-trimester (MT1) pregnant women. Materials and Methods: A total of 147 MT1 pregnant women were included in the study, who were divided into 3 groups based on their health status: Group 1 (Control group) included basically healthy women (n=24); Group 2 (Risk group) included women defined as vulnerable to risk factors (n=32); Group 3 (Threatened group) included women hospitalized for threatened miscarriage (n=35). In Groups 2 and 3, patients were divided into 3 age groups: 18-24 years, 25-34 years, and ≥35 years. Patients in the Control group were divided into 2 age groups, 18-24 years and 25-34 years, since women aged ≥35 years were referred to Group 2. The psychoemotional status of the women was assessed using the Spielberger State-Trait Anxiety Inventory (STAI) in Yu.L.Khanin's adaptation, and the Eysenck Personality Questionnaire (EPQ). Results: The results of our study showed the presence of age-specific features in the psychophysiological state of pregnant women living in the North, specifically, high anxiety levels. In all patient groups, psychoemotional stress tended to increase with age. The highest stress levels were observed among pregnant women from the Threatened miscarriage group, especially in 2 age subgroups (18-24 years and ≥35 years).
