DYNAMICS AND FORECAST OF MORTALITY AMONG NEWBORNS IN OBSTETRIC ORGANIZATIONS OF THE RUSSIAN FEDERATION

Abstract

Decrease of mortality among newborns is a key problem of the reduction of mortality in total children’s population. Mortality rate among newborn in obstetric hospitals within the period of 2013-2019 had an absolutely definite tendency of decrease. Besides, this decrease was noted among both the newborns born with a body weight of 1000 g or more (-48.8 %), and the children born with an extremely low body weight (-47.4 %). The most essential contribution to the mortality rate level among the newborns born with a body weight of 1000 g or more was made by premature children mortality. The estimation of the mortality rate of the newborns born with a body weight of 500-999 g indicated that in 2019 this mortality level was 13.4 times higher than in premature newborns born with a body weight of 1000 g or more (135.6‰ vs 10.1‰; p <0.05). The most frequent causes of pediatric death in obstetric care organizations were individual conditions occurring in the perinatal period which specific percentage varied depending on the gestational age. It was noticed that during the analyzed period the mortality among children due to congenital anomalies (malformations) considerably decreased. According to the prognosis, by 2024 the mortality rate among the newborns born with a body weight of 1000 g or more, will 5.5 times decrease as compared to the level of 2019 (up to 0.24 per 1000 live births), and the mortality rate among the newborns born with a body weight of 500-999 g can become 3.4 times lower (39.32 per 1000 live births). Thus, mortality rate decrease among full term and premature children in obstetric ca
