The epidemiology of premenstrual dysphoric disorders (PMDD) and the risk factors for PMDD in women of the Russian Federation are still not fully resolved. Objective: to assess the prevalence of PMDD among women in the Russian Federation and to identify risk factors for PMDD. Materials and methods. An anonymous questioning using the questionnaire was carried out by 1326 women of the reproductive period of different regions of the Russian Federation: Moscow (880), Ural (150), Rostov (146) and Novosibirsk (150) regions. Inclusion criteria were: age of 15-45 years, regular menstrual cycle of 25-35 days, lack of psychiatric diagnoses in history. The results. It was found that 15.6 % of Russian women meet the criteria for PMDD. The primary age of the first appearance of PMDD symptoms is 15-19 years. The statistically significant risks of developing PMDD are ages 15-24 years, education at a higher education institution, lack of regular sexual life, history of neurocirculatory dystonia, complication of heredity in neuropsychiatric diseases and premenstrual syndrome, painful periods and complications in childbirth or abortion. Conclusions: the high prevalence of PMDD (15.6 %) in young women of the reproductive period, the presence of psychosocial and biological risk factors for PMDD requires the development of a modified tool for the early diagnosis of PMDD for general practitioners, obstetrician gynecologists, and psychiatrists.
