The article identifies the main types of factors affecting the growth of reproductive losses of the population. Based on the survey data, the main risk factors among respondents that could serve as predictors of the growth of reproductive losses and the occurrence and development of internal fetal malformations were identified and analyzed. An increase in the risks of reproductive losses was found in the presence of genetic disorders in close relatives, due to the age of a pregnant woman of 35 or more years and in the presence of psychoemotional overload. Anatomical abnormalities of the uterine structure and immune-hormonal disorders were identified as key medical factors. The main demographic and socio-behavioral risk factors of socially determined risks of reproductive losses and high levels of their prevalence have been identified. The results obtained were correlated to determine the odds ratio between individual risk factors and were used as the basis for creating a prognostic model of risk factors for reproductive losses of the population of residents of the Magadan region.
