Purpose: to investigate lifestyle characteristics in women with post-traumatic stress disorder (PTSD) and their role in the development of recurrent pregnancy loss (RPL). The object of research: lifestyle of reproductive-age women (20–40 years) with PTSD. The subject of research: impact of adverse lifestyle factors (smoking, alcohol and caffeine consumption, sleep disorders, insufficient physical activity) on the frequency of RPL in women with PTSD. Methods: clinical interviewing, analysis of medical records, standardized questionnaires (Health-Promoting Lifestyle Profile II, PCL-C, CAPS-5), gynecological and ultrasound examinations, laboratory and statistical methods. Results. Women with PTSD showed a high prevalence of sleep disorders (up to 63.3%) and harmful habits (excessive caffeine intake — up to 30%, alcohol — up to 25%, smoking — up to 30%), along with a lack of awareness regarding their impact on reproductive health. No significant difference in body mass index was found between women with and without PTSD. The findings highlight the need to incorporate preventive, educational, and psychotherapeutic strategies into the clinical management of women with RPL and PTSD. Conclusion. Lifestyle is a significant modifiable factor in the development of RPL in women with PTSD. Implementation of multidisciplinary lifestyle correction programs is advisable as part of comprehensive therapy.
