In 2013–2016 years we examined 403 men (mean age – 34±0.4 years, response – 71%) and 531 women (mean age – 35±0.4 years, response – 72%) from an open population of 25–44 year old residents of the Oktyabrsky district, Novosibirsk, the sample was representative. Depression was assessed using the MONICA-MOPSY psychosocial questionnaire. Genotyping of the studied gene polymorphisms was carried out in the Laboratory of Molecular Genetic Research of Scientific Research Institute for Therapy and Preventive Medicine, Federal Research Center Institute of Cytology and Genetics, Russian Academy of Sciences, Novosibirsk.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. A severe level of depression occurred in 12.8% of the population, among men – in 8.9%, among women – in 15.8%; and moderate level – in 24.5% of the population (among men – 21.3%, among women – 26.9%). The most common in the population was the heterozygous C/G genotype (45.1%), the G/G genotype was observed in 34.6% of the population and, finally, C/C in 20.3% of participants. The most common allele of the IL-6 gene of the G-174C polymorphism (rs1800795) was the G allele in 57.5% of the population, and the C allele in only 42.5%. Among carriers of the G/G genotype of the IL-6 gene, a moderate (39.7%) or severe level of depression (37.3%) prevailed, while there was no depression in the carriers of the C/C genotype of the IL-6 gene (24.2%; χ2 = 10.962; df=4; p=0.027). Carrying the C/G genotype of the IL-6 gene increased the chance of developing a severe level of depression by almost 2.9–3.3 times in comparison with the carriage of the C/C genotype. Among carriers of the G/G genotype of the IL-6 gene, a severe level of depression was 3.3 times more common than in carriers of the C/C genotype. Individuals carrying the G allele of the IL-6 gene were 1.6 times more likely to experience a severe level of depression than those carrying the C allele.</p></sec><sec><title>Conclusion</title><p>Conclusion. The data obtained suggest that the carriage of the G allele of the G-174C polymorphism (rs1800795) of the IL-6 gene may be associated with a severe level of depression. </p></sec></abstract><trans-abstract xml:lang="ru"><p>Цель исследования – изучить ассоциации полиморфизма G-174C (rs1800795) гена IL-6 с депрессией в открытой популяции населения 25–44 лет г. Новосибирска.</p><sec><title>Пациенты и методы</title><p>Пациенты и методы. В 2013–2016 гг. обследованы 403 мужчины (средний возраст – 34±0,4 года, респонс – 71%) и 531 женщина (средний возраст – 35±0,4 года, респонс – 72%) репрезентативной выборки из открытой популяции жителей 25–44 лет Октябрьского района г. Новосибирска. Депрессия была оценена с помощью психосоциального опросника MONICA-MOPSY. Генотипирование изучаемых полиморфизмов генов проводилось в лаборатории молекулярно-генетических исследований НИИТПМ – филиала ИЦиГ СО РАН г. Новосибирск.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Высокий уровень депрессии встречался у 12,8% населения, среди мужчин – у 8,9%, среди женщин – у 15,8%; средний уровень – у 24,5% населения (среди мужчин – у 21,3%, среди женщин – у 26,9%). Наиболее часто встречаемым в популяции оказался гетерозиготный генотип С/G (45,1%), генотип G/G наблюдался у 34,6% населения и, наконец, C/C – у 20,3% участников. Наиболее часто встречаемым аллелем гена IL-6 полиморфизма G-174C (rs1800795) был аллель G – у 57,5% населения, а аллель С – только у 42,5%. Среди носителей генотипа G/G гена IL-6 преобладал средний (39,7%) либо высокий уровень депрессии (37,3%), а у носителей генотипа C/C гена IL-6 депрессия отсутствовала (24,2%; χ2 =10,962; df=4; p=0,027). Носительство генотипа С/G гена IL-6 увеличивало шанс развития высокого уровня депрессии почти в 2,9–3,3 раза в сравнении с носительством генотипа С/С. Среди носителей генотипа G/G гена IL-6 высокий уровень депрессии встречался в 3,3 раза чаще в сравнении с носителями генотипа С/С. Лица – носители аллеля G гена IL-6 в 1,6 раза чаще испытывали высокий уровень депрессии, чем носители аллеля С.</p></sec><sec><title>Заключение</title><p>Заключение. Полученные данные позволяют предполагать, что носительство аллеля G полиморфизма G-174C (rs1800795) гена IL-6 может быть связано с высоким уровнем депрессии. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>популяция</kwd><kwd>мужчины</kwd><kwd>женщины</kwd><kwd>ген IL-6</kwd><kwd>депрессия</kwd><kwd>полиморфные маркеры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>population</kwd><kwd>men</kwd><kwd>women</kwd><kwd>IL-6 gene</kwd><kwd>depression</kwd><kwd>polymorphic markers</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в рамках бюджетной темы № 122031700094-5.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Sullivan P, Neale M, Kendler K.
