Изучение взаимосвязи между уровнем госпитализаций, тяжелого течения и летальности от новой коронавирусной инфекции (COVID-19) с частотой потребления электронных сигарет (ЭС) в Российской Федерации (РФ) за 2020-2021гг.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Проанализированы данные о числе госпитализированных с COVID-19 (COrona VIrus Disease 2019) тяжелого течения и умерших от COVID-19 за 2020-2021гг в 85 субъектах РФ из Федерального регистра COVID-19, данные о статусе потребления ЭС, за 2020-2021гг по 85 субъектам РФ из базы микроданных "Выборочного наблюдения состояния здоровья населения" Росстата (Федеральная служба государственной статистики). Проведен анализ взаимосвязи частоты потребления ЭС с уровнем госпитализации с COVID-19, тяжелых COVID-19 и летальности от COVID-19 по половозрастным группам и федеральным округам (ФО) РФ в модели квадратичной регрессии.</p></sec><sec><title>Результаты</title><p>Результаты. Получены нелинейные взаимосвязи между исследуемыми показателями с характерной параболической зависимостью. Выявлена статистически значимая связь летальности от COVID-19 с частотой потребления ЭС у мужчин в возрасте 15-19 лет (R2=0,24, p=0,001); у женщин 30-39 лет (R2=0,13, p=0,001). Связи между уровнем госпитализаций, тяжелых и летальных случаев COVID-19 и потреблением ЭС в большинстве ФО демонстрируют обратную параболическую зависимость.</p></sec><sec><title>Заключение</title><p>Заключение. Взаимосвязи между частотой потребления ЭС и показателями COVID-19 сложны и нелинейны. Глубокий сегментированный анализ позволил выявить значимые ассоциации, объясняющие вклад потребления ЭС в уровень госпитализаций, тяжелых и летальных исходов COVID-19 в отдельных половозрастных группах. В разрезе ФО РФ эти связи характеризуются неоднородностью, очевидно в силу воздействия ряда демографических и социально-экономических факторов на исходы COVID-19.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To study the relationship between hospitalizations, severity and mortality from a coronavirus disease 2019 (COVID-19) with the frequency of e-cigarette (EC) consumption in the Russian Federation for 2020-2021.</p></sec><sec><title>Material and methods</title><p>Material and methods. The data on the number of people hospitalized with severe COVID-19 and those who died from COVID-19 for 20202021 in 85 Russian regions from the Federal Registry of COVID-19, as well as data on the status of EC consumption for 2020-2021 in 85 Russian regions from the Rosstat micro-database of the Sample Monitoring of the Population Health were analyzed. An analysis of the relationship between the frequency of EC consumption and the level of hospitalization with COVID-19, COVID-19 severity and mortality by sex and age groups and federal districts (FD) of the Russian Federation was carried out in the quadratic regression model.</p></sec><sec><title>Results</title><p>Results. Nonlinear relationships between the studied parameters with a characteristic parabolic dependence were obtained. A significant relationship was found between COVID-19 mortality and the frequency of EC consumption in men aged 15-19 years (R2=0,24, p=0,001); in women aged 30-39 years (R2=0,13, p=0,001). The relationships between the level of hospitalizations, severe and fatal outcomes of COVID-19 and EC consumption in most federal districts demonstrate an inverse parabolic relationship.</p></sec><sec><title>Conclusion</title><p>Conclusion. The relationships between the frequency of EC consumption and COVID-19 indicators are complex and nonlinear. Deep segmented analysis revealed significant associations explaining the contribution of EC consumption to the level of hospitalizations, severe and fatal outcomes of COVID-19 in certain age and sex groups. In the context of the federal districts of the Russian Federation, these relationships are characterized by heterogeneity, apparently due to the impact of a number of demographic and socio-economic factors on COVID-19 outcomes.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>коронавирусная инфекция</kwd><kwd>COVID-19</kwd><kwd>табак</kwd><kwd>электронные сигареты</kwd><kwd>вейпинг</kwd><kwd>госпитализации COVID-19</kwd><kwd>летальность от COVID-19</kwd><kwd>тяжелая COVID-19</kwd></kwd-group><kwd-group xml:lang="en"><kwd>coronavirus infection</kwd><kwd>COVID-19</kwd><kwd>tobacco</kwd><kwd>e-cigarettes</kwd><kwd>vaping</kwd><kwd>COVID-19 hospitalizations</kwd><kwd>COVID-19 mortality</kwd><kwd>severe COVID-19</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Драпкина О.
