[The analysis of mortinatality in the Bryansk oblast and the Russian Federation].

On the basis of official statistics of 1995-2014 a comparative analysis of the dynamics of stillbirths of boys and girls in the Bryansk region and the Russian Federation was carried out. The study established exceeding of rate of stillbirths in boys over stillbirths in girls at 14.4% and 9.0% correspondingly both in the Bryansk Oblast and the Russian Federation that confirms the global trend of higher risk of stillbirth in boys by approximately to 10%. In case the stillbirth rate in the Bryansk Oblast will proceed established trend the ratio of stillbirths will increase relatively to the nationwide values in 2016 - 2021 and will reach 30% in 2021. At that, the gap between indices of boys and girls will increase up to 32,8%.

[Comparative evaluation of the prevalence of congenital malformations de novo in newborns from radiation-contaminated territories of the Bryansk region (1999-2014)].

On the basis of official statistics for 1999-2014 there was performed the comparative evaluation of the prevalence of congenital malformations de novo: polydactyly, reduction limb defects and multiple congenital malformations in newborns of radiation-contaminated areas of the Bryansk area residing in areas with the various density of radioactive contamination by long lived radionuclides cesium-137 (from 10.0 to 2523.4 kBq/m) and strontium-90 (from 0.7 to 42.5 kBq/m). The findings showed no statistically significant differences in the prevalence of polydactyly, reduction limb defects and multiple congenital malformations in newborns in the South-Western areas compared to medium regional values, although the maximum value of the amount of congenital malformations de novo is found in most radiation-contaminated areas.

The Dynamics of the Frequency of Polydactyly, Reduction Defects of Limbs and Multiple Congenital Malformations in Newborns of Radioactively Contaminated Areas of the Bryansk Region (1999-2014).

On the basis of official statistical data for 1999-2014 the authors assessed the frequency of polydactyly, reduction defects of limbs and multiple congenital malformations in newborns of the Bryansk region living in the areas with different densities of radioactive contamination by long-lived radionuclides cesium-137.(3.0 to 2523.4 kBq/m(2)) and strontium-90 (from 0.02 to 42.5 kBq/M(2)). The findings did not reveal statistically significant differences in the frequency of polydactyly, reduction defects of limbs and multiple congenital malformations in newborns in the South-Western Territories compared with medium-regional values, although the maximum value of the sum of congenital. developmental anomalies (polydactyly, reduction limb defects and multiple congenital malformations) are detected in the above-mentioned most contaminated areas.
