G. Kuvatov Republican Clinical Hospital for the period 2005–2023. During this period, 2,967 patients (10,303 person-years) were treated at the RCMS, of whom 297 died. Life expectancy was assessed using the Gehan–Breslow test. Standardised mortality rates (SMR) were calculated. The causes of death were determined based on information from the Republican Medical Information and Analytical System of the RB.</p></sec><sec><title>   Results</title><p>   Results. In more than 70 % of cases, the cause of death may be related to MS and its complications. The overall SMR rate among patients was 1.92. The average life expectancy of MS patients is 19.1 years shorter than that of the general population. The median survival rate of patients was 32 years on average. The average life expectancy for women with MS was significantly higher than for men.</p></sec><sec><title>   Conclusion</title><p>   Conclusion. In the RB, the presence of MS increases the risk of premature death and reduces the patient's life expectancy. The indicators studied in the republic reflect global patterns and trends.</p></sec></abstract><trans-abstract xml:lang="ru"><p>   Представлены результаты впервые проведенного анализа продолжительности жизни, смертности, а также причин смерти больных с рассеянным склерозом (РС) в Республике Башкортостан (РБ).</p><p>   Цель исследования – изучить показатели продолжительности жизни и структуру смертности среди пациентов с РС в РБ.</p><sec><title>   Материал и методы</title><p>   Материал и методы. При оценке показателей использовались данные регистра больных Республиканского центра рассеянного склероза (РЦРС) на базе Республиканской клинической больницы им. Г. Г. Куватова за период 2005–2023 гг. В указанный период в РЦРС прошли лечение 2967 пациентов (10 303 человеко-года), из которых 297 умерли. Продолжительность жизни оценивали с помощью теста Гехана–Бреслоу. Рассчитаны стандартизированные коэффициенты смертности (СКС). Причины смерти были установлены на основании сведений из Республиканской медицинской информационно-аналитической системы РБ.</p></sec><sec><title>   Результаты</title><p>   Результаты. Более чем в 70 % случаев причина смерти может быть связана с РС и его осложнениями. Общий показатель СКС среди больных составил 1,92. Ожидаемая продолжительность жизни больных РС в среднем на 19,1 года короче по сравнению с общей популяцией. Медиана выживаемости пациентов в среднем составила 32 года. Средняя продолжительность жизни у женщин с РС была значимо больше, чем у мужчин.</p></sec><sec><title>   Заключение</title><p>   Заключение. В РБ наличие РС увеличивает риск преждевременной смерти и сокращает длительность жизни больного. Исследуемые показатели в республике отражают общемировые закономерности и тенденции.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рассеянный склероз</kwd><kwd>продолжительность жизни</kwd><kwd>смертность</kwd><kwd>факторы риска</kwd></kwd-group><kwd-group xml:lang="en"><kwd>multiple sclerosis</kwd><kwd>life expectancy</kwd><kwd>mortality</kwd><kwd>risk factors</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование не имело спонсорской поддержки</funding-statement><funding-statement xml:lang="en">The investigation has not been sponsored</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">Leadbetter R, MacAskill M, Myall DJ, et al.
