После создания Уральской когорты аварийно-облученного населения, объединяющей лиц, облученных в двух авариях в период с 01.01.1950 по 31.12.1960 годы на Южном Урале, численность когорты увеличилась в 2 раза, период наблюдения достиг 71 года, а число человеко-лет под риском увеличилось до 1 964 333. Средняя доза на красный костный мозг всех членов когорты составила 231 мГр. Регрессионный анализ с использованием простой параметрической модели избыточного относительного риска был проведен с помощью статистического пакета EPICURE. В результате анализа было получено подтверждение статистически значимой (р&lt;0,001) линейной зависимости смертности от всех гемобластозов, и лейкозов от дозы. Избыточный относительный риск смерти и 95% доверительные интервалы при 2-летнем латентном периоде от всех гемобластозов составили 0,71/Гр (0,28; 1,31); от всех лейкозов — 1,28/Гр (0,55-2,39) и от лейкозов с исключением хронического лимфолейкоза — 1,52/Гр (0,64-2,94). При этом квадратичная модель также значимо описывала дозовую зависимость, (различия между моделями были не значимы). Увеличение периода наблюдения до 71 года привело к незначительному уменьшению оценок риска. Ширина доверительных интервалов показателей риска уменьшилась более, чем в 3 раза относительно ранних исследований в когорте реки Течи, что указывает на уменьшение неопределенностей оценок риска. Увеличение численности когорты позволило получить значимые величины риска для отдельных групп населения (по полу, возрасту и др.). Анализ модификации величин риска не выявил значимых различий дозовой зависимости от исследуемых факторов, включая достигнутый возраст и возраст на начало наблюдения. исследование будет продолжено для более детального изучения влияния временно-зависимых факторов на дозовую зависимость, а также для оценки риска смерти от отдельных клеточных форм лейкозов.</p></abstract><trans-abstract xml:lang="en"><p>The results of studies of long-term effects of population exposure in the South Urals in the 1950s were based for a long time on studies of the effects of exposure in the Techa River cohort and later in the East Urals Radioactive Trace cohort. After the creation of the South Urals Population Exposed to Radiation cohort, combining all persons exposed in the South Urals in the period from January 1, 1950, to December 31, 1960 the size of the cohort doubled, follow-up period reached 71 years, and the number of person-years at risk increased to 1,964,333. The average dose to red bone marrow for all cohort members was 231mGy. Regression analysis using a simple parametric excess relative risk model was performed using the EPICURE statistical package. The analysis resulted in confirmation of a statistically significant (p &lt;0.001) linear doseresponse relationship of mortality for all hemoblastoses, and leukemia. The excess relative risk and 95% confidence intervals of death at 2-year latency period from all hemoblastoses were 0.71/Gy (0.28;1.31); from all leukemias - 1.28/Gy (0.55-2.39) and from leukemias excluding chronic lymphocytic leukemia -1.52/Gy (0.64-2.94). The quadratic model also significantly described the dose dependence; (the differences between the models were not significant). Increasing the follow-up period to 71 years resulted in a slight decrease in risk estimates. The width of the confidence intervals of the risk estimates decreased by more than a factor of 3 compared to earlier studies in the Techa River cohort, which indicates a decrease in uncertainties of risk estimates. Increasing the size of the cohort made it possible to obtain significant risk values for individual population groups (by sex, age, etc.). Analysis of risk values modification did not reveal significant differences in dose dependence on the studied factors, including attained age and age at exposure. The study will be continued to investigate in more detail the influence of time-dependent factors on dose dependence, as well as to assess the risk of death from different cellular forms of leukemia.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лейкоз</kwd><kwd>гемобластозы</kwd><kwd>избыточный относительный риск</kwd><kwd>риск смерти</kwd><kwd>хроническое облучение</kwd><kwd>Уральская когорта аварийно-облученного населения</kwd><kwd>УКАОН</kwd></kwd-group><kwd-group xml:lang="en"><kwd>leukemia</kwd><kwd>hemoblastoses</kwd><kwd>excess relative risk</kwd><kwd>risk of death</kwd><kwd>chronic exposure</kwd><kwd>South Urals Population Exposed to Radiation cohort</kwd><kwd>SUPER</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено в рамках выполнения НИР по Государственному заданию при финансовой поддержке ФМБА России в 2023 г.
