INTEGRATED ASSESSMENT OF THE DEMOGRAPHIC STATE OF RADIOLOGICALLY CONTAMINATED AREAS OF UKRAINE. / INTEGRAL'NE OTsINIuVANNIa DEMOGRAFIChNOGO STANU RADIOAKTYVNO ZABRUDNENYKh TERYTORII UKRAÏNY.

OBJECTIVE: Basing on the integrated assessment to conduct a comparative statistical analysis as of 2016 of thedemographic state of the areas of Ukraine that are recognized as those with the most intensive radiological con-tamination due to the Chornobyl NPP accident.Study object. The population of the regions of Ukraine with the most intensive radiological contamination due tothe Chornobyl NPP accident and the population of Ukraine as a whole (control). MATERIALS AND METHODS: The data of the State Statistics Service of Ukraine and its regional offices were used asinformation base in this study. Integrated assessment of the demographic situation in a oblast was conducted basedon the calculations of the territorial indices and multidimensional average variable on each region. Demographic,mathematical-statistical, graphic, software-technological methods were used in this study. RESULTS AND CONCLUSION: Radiologically contaminated regions of Ukraine differ significantly: both by the number ofpopulation (from 5800 people in the Poliske region to 105100 people in the Sarny region), and by the variability inthemedical and demographic indicators; bothone from another and compared to data for the country.The results of the calculations of 10 medical and demographic («positive¼ and «negative¼) territorial indices andmultidimensional average variable (P) as integrative assessment of the demographic state have revealed that thebest indicators of the demographic situation in 2016 were in Rokytne (P = 1.249) and Sarny (P = 1.112) regions ofthe Rivne oblast, while the worse indicators were in Kozelets (P = 0.363) and Ripky regions of the Chernihiv oblast.The demographic situation of the Olevsk region of the Zhytomyr oblast (P = 0.947)was the closest to the nationalaverage one. Poliske, Narodychi, Ovruch, Ivankiv and Korosten regions take intermediate position as comparedto theregions of Rivne and Chernihiv oblasts (P = 0.618-0.742).

Information and statistical support for retrospective study of mortality among people exposed in childhood as a result of the Chornobyl accident and living in contaminated areas of Ukraine: assessment of feasibility. / INFORMATsIY̆NO STATYSTYChNE ZABEZPEChENNIa RETROSPEKTYVNOGO DOSLIDZhENNIa SMERTNOSTI OSIB, OPROMINENYKh U DYTIaChOMU VITsI VNASLIDOK AVARIÏ NA ChORNOBYL'S'KIY̆ AES TA PROZhYVAIuChYKh NA RADIOAKTYVNO ZABRUDNENYKh TERYTORIIaKh UKRAÏNY: OTsINKA PRAKTYChNOÏ MOZhLYVOSTI.

OBJECTIVE: Analysis of information from various sources for its use in epidemiological study on mortality of people (born in 1968-1986) who were children and adolescents at the time of the Chornobyl accident. OBJECT OF STUDY: Information and statistical sources for 1986-2011 on mortality among people who were children and adolescents at the time of the Chornobyl accident and lived on the most radioactive contaminated territories (RCT) of Ukraine (Ivankiv and Polisske regions of Kyiv oblast, Narodychi and Ovruch regions of Zhytomyr oblast). RESEARCH METHODS: theoretical, general scientific, documentary analysis, demographic. RESULTS AND CONCLUSIONS: The study is to determine the suitability of available information and statistical support for measuring and assessing mortality of people exposed in childhood as a result of the Chornobyl accident and liv ing in contaminated areas of Ukraine. A combination of information and statistical data provided by SRU, Ministry of Justice of Ukraine, State Statistics Service (SSS) of Ukraine and NNCRM makes it possible to successfully conduct retrospective cohort studies in any area and for any period.
