[Sonographic parameters of spleen in children depending on the level of anthropogenic pollution of areas of residence].

Sonographic parameters of spleen in children living in the Orenburg region taking into account the level and character of anthropogenous pollution of territory of residing are studied. The analysis of indicators of pollution of factors of inhabitancy (atmospheric air, potable water soil) is carried out. One-stage population research of 7000 children aged from 1 to 18 years living in urbanized and rural territories is conducted.

[Children's health status in relation to the level and nature of anthropogenic pollution].

The frequency of health groups 1 and 2 was studied in children living in the areas of the Orenburg Region, by taking into account the level and nature of their anthropogenic pollution. The pollution indicators of environmental objects (ambient air, drinking water, soil) were analyzed. A cross-sectional population-based study was conducted in 7000 children aged 1 month to 18 years, who lived in the urban and rural areas.

[Normal values of temporal parameters of ECG in children according to results of clinico-epidemiological study ECG-screening of children and adolescents in Russian federation].

In order to obtain reliable information about time-domain ECG parameters in Russian children and to analyse their links with physiological changes the Project "ECG screening of children and adolescents of the Russian Federation" was carried out in 2003-2008. Time domain ECG parameters were studied in the representative sample of 5387 healthy individuals aged 0 to 18 years. In each age group, lower and upper limits of the norm for heart rate (HR), P wave, PQ and QRS intervals were defined as 2nd and 98th percentiles of their distribution.

[Propagation and structure of noninfectious diseases in children and adolescents living in regions with various anthropogenic load].

A survey was made in 3205 children aged 6-17 years from the families of natives residing in the areas exposed to nuclear explosion (Group 1). A control group comprised 3200 children living under the similar climatogeographic and social conditions (Group 2). In Group 1 children circulatory diseases, lymphadenopathies, connective and bone tissue dysplasias come first in the structure of morbidity.

[Health status of children living in rural localities in the area of Totsk nuclear explosion].

The paper presents late outcomes of radiation exposure of 3205 children aged 6-17 years from native persons residing in the areas exposed to radiation 40 years ago. The spread of noncommunicable diseases in the children from the polluted area is 92%. Organic abnormalities are prevalent among them.
