RESUMO
147318 pregnancy outcomes were analyzed in Zhytomyrska Oblast during 2000-2010; the descriptive analysis was performed. The frequency of birth defects was estimated among newborns, still-born babies and abortions due to genetic disorders of a fetus on "clean" and polluted territories. There was an increase of all birth defects on the polluted territories; among newborns it was (26.10 ± 0.80) per thousand and (24.23 ± 0.47) per thousand, p < 0.05; among newborns and still-born babies it was (26.54 ± 0.81) per thousand and (24.78 ± 0.48) per thousand, p < 0.06. The increase in the birth defects of the nervous system was detected: among newborns it was (1.09 ± 0.17) per thousand and (0.75 ± 0.08) per thousand, p < 0.05; among newborns and still-born babies it was (1.22 ± 0.18) per thousand and (0.81 ± 0.09) per thousand, p. < 0.05; among newborns, still-born babies and genetically caused abortions it was 2.76 ± 0.26) per thousand and (2.34 ? 0.15) per thousand, p = 0.165. Χ2 criteria confirmed the difference between the frequency of birth defects on "clean" and polluted territories. Estimation by Bayes did not confirm the hypothesis about the difference between the frequency of birth defects on "clean" and polluted territories. Endocrine diseases were confirmed to be an important factor of the origin of birth defects, which is important for planning pregnancy on both polluted and "clean" territories.
