Age peculiarities of reproductive morbidity in female participants of the ChNPP accident consequences clean-up (according to the figures from SRU, 19882012 survey period)

Objective: to assess and estimate the peculiarities of genital system morbidity in female participants of the ChNPP accident clean-up works in 19861987 depending on age at exposure to ionizing radiation and time since exposure.
Materials and methods. Data on the Chernobyl disaster survivors received from the State Registry of Ukraine are outline in the paper. Review of the level and pattern of genital system morbidity was carried out for the 17,237 female participants of the ChNPP accident clean-up works in 19861987 depending on time under risk upon radiation exposure and reproductive age at exposure. Survey period lasted since 1988 till 2012. Assessment of morbidity level, confidential intervals, and statistical significance was carried out using the trial version of penEpiversion 2.3.1. software. Statistical significance was also rated using the z-score and t-criterion.
Results. The results of this cohort epidemiological study showed that there are some peculiarities of natural course of the female genital system disease depending on reproductive age at exposure and time under risk upon radiation impact. Comparative statistical review of the level and pattern of genital system morbidity at different times within a survey period.
Conclusion. Exposure to ionizing radiation in the childbearing age (1845 years old) can be a risk factor of elevated incidence of uterine leiomyoma, benign mammary dysplasia (i.e. benign breast disease), and salpingo-oophoritis. It is far to assume that uterine and mammary tissues are more sensitive to impact of ionizing radiation in females of the childbearing age vs. in persons exposed in pre-menopause or menopause.

Key words: ionizing radiation, female participants of the ChNPP accident clean-up, genital system disease.
