В работе проанализированы данные 333 психически здоровых студентов из Республики Башкортостан. Использовались методы генетического анализа (ПЦР, флуоресцентная детекция) и психометрического тестирования (опросник Спилбергера-Ханина). Выявлены значимые ассоциации полиморфных локусов rs6265 и rs712442 гена BDNF с вариациями в уровне тревожности. Аллель rs6265*A ассоциирован с более низкими показателями личностной тревожности (β = -1,748; p = 0,02), а аллель rs712442*T – с более высоким уровнем ситуативной тревожности (β = 1,27; p = 0,03). Кроме того, обнаружены ген-средовые взаимодействия между полиморфизмами BDNF и перенесенным COVID-19, влияющие на уровень ситуативной тревожности. Также выявлены различия в тревожности в зависимости от пола, возраста матери при рождении ребенка, веса при рождении, приема антибиотиков и гормональной терапии. Полученные данные подчеркивают важность комплексного подхода к изучению тревожности, учитывающего как генетические, так и средовые факторы.</p></abstract><trans-abstract xml:lang="en"><p>The study is devoted to investigating the genetic predisposition to anxiety disorders, particularly the role of the BDNF (brain-derived neurotrophic factor) gene in the formation of state and trait anxiety. The work analyzed data from 333 mentally healthy students from the Republic of Bashkortostan. Methods of genetic analysis (PCR, fluorescence detection) and psychometric testing (Spielberger-Hanin questionnaire) were used. The results revealed significant associations of the polymorphic loci rs6265 and rs712442 of the BDNF gene with variations in anxiety levels. The rs6265A allele was associated with lower levels of trait anxiety (β = -1.748; p = 0.02), while the rs712442T allele was linked to higher levels of state anxiety (β = 1.27; p = 0.03). Additionally, gene-environment interactions between BDNF polymorphisms and the history of COVID-19 were found to influence state anxiety levels. Differences in anxiety were also identified based on gender, maternal age at childbirth, birth weight, antibiotic use, and hormone therapy. The findings emphasize the importance of a comprehensive approach to studying anxiety, considering both genetic and environmental factors.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>генетика поведения</kwd><kwd>психогенетика</kwd><kwd>нейротрофический фактор головного мозга</kwd><kwd>тревожность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>behavioral genetics</kwd><kwd>psychogenetics</kwd><kwd>brain-derived neurotrophic factor</kwd><kwd>anxiety</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Данное исследование не получало внешнего финансирования</funding-statement><funding-statement xml:lang="en">This research received no external funding</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">Hettema J.M., Neale M.C., Kendler K.S.
