EVALUATION OF THE FREQUENCY AND STRUCTURE OF ABORTIONS IN THE REGION OF CENTRAL RUSSIA

Abortion occupies a leading place in the structure of reproductive losses. The purpose of the study is to assess the structure and frequency of abortions in the Tula region Russia. Material and methods. In the period from 2013 to 2017, the analysis of the dynamics of fertility and abortion in the period up to 22 weeks was carried out. Results. During 5 years in the region of 73 517 was born living children. The analysis showed that the number of termination of pregnancy was 25 126, of them in the early stages (up to 12 weeks) 23 396 (93.1%), in the period from 12 to 22 weeks - 1730 (6.9%). The number of abortions in the region to 22 weeks decreased from 47.9 to 29.4 per 1,000 women (15-49 years) and from 19.9 to 11.4 per 100 born alive and dead. Compared with other types of abortion, the lowest basic rate of decline (9.97%) was set for spontaneous abortion (9.97%), the highest for medical legal abortion - 62.11%. In the structure of termination of pregnancy up to 12 weeks there was an increase of spontaneous abortion for 2015 -2017 (the basic growth rate of 16.6%). In the region, there was an increase in the frequency of abortions in the first pregnancy by 33.9% and an increase in abortions for medical reasons by 16.85%. The age ratio of abortions remains stable throughout the follow-up period. Conclusion. The structure of reproductive losses in the region is still dominated by medical legal abortions, but among the true prenatal losses the leading role belongs to spontaneous abortion. Reducing the frequency of spontaneous abortion is the main unconditional reserve to increase the reproductive potential of the region.
