Однако для диагностики заболевания применяются критерии различных профессиональных международных групп, что приводит к большой вариабельности данных о частоте саркопении в популяции. В работе представлены результаты изучения частоты саркопении с использованием критериев диагностики разных рабочих групп. Проведен анализ показателей, характеризующих мышечную силу и функцию скелетных мышц, выявлены компоненты, наиболее значимые для диагностики саркопении в изучаемой группе пациентов.</p><p>Цель исследования – определить частоту выявления саркопении среди лиц старше 65 лет в соответствии с рекомендациями различных профессиональных международных групп, выделить наиболее значимый для ее диагностики компонент.</p><sec><title>Материал и методы</title><p>Материал и методы. В исследование включены 230 человек старше 65 лет (средний возраст – 74,0±6,5 года), наблюдавшихся амбулаторно. Диагностика саркопении проводилась на основании критериев Европейской рабочей группы по изучению саркопении (European Working Group on Sarcopenia in Older People, EWGSOP) 2010 г. Для подтверждения диагноза проводился расчет индекса аппендикулярной мышечной массы (ИАММ) с помощью двухэнергетической абсорбциометрии (DХА) на аппарате HOLOGIC Explorer QDR, мышечная сила измерялась кистевым динамометром Jamar-J00105 (Sammons Preston Inc., США). Мышечную функцию также изучали на основе краткого комплекса тестов физической работоспособности (Short Physical Performance Battery, SPPB). Проводился сравнительный анализ частоты саркопении, диагностированный по критериям Международной рабочей группы по изучению саркопении (International Working Group on Sarcopenia, IWGS), Фонда Национального института здоровья (Foundation for the National Institutes of Health, FNIH) и EWGSOP2 (2018).</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Частота саркопении в выборке людей старше 65 лет была сопоставима при использовании для диагностики критериев EWGSOP и IWGS (30%) и оказалась значительно выше, чем по критериям FNIN (19,8%). Частота саркопении увеличивалась с 21,4% в возрасте 65–74 года до 52,9% в возрасте старше 85 лет по критериям EWGSOP IWGS и соответственно с 16,2 до 29,4% по критериям FNIN. Мышечная сила по результатам динамометрии у пациентов с низкой мышечной массой была достоверно меньше, чем у больных с нормальной мышечной массой (в среднем 15,1±5,4 и 18,2±5,4 кг соответственно; р&lt;0,001) как среди мужчин, так и среди женщин. Средний счет SPPB-тестов в целом по выборке был низким во всех исследуемых группах (7,6±3,1 балла). У пациентов с низкой мышечной массой он оказался значимо ниже, чем у лиц с нормальной мышечной массой (6,9 и 7,9 балла соответственно; р=0,016), преимущественно за счет теста «Тандем» (р=0,0002). Не было выявлено существенных различий частоты саркопении в разных возрастных группах согласно критериям EWGSOP и EWGSOP2.</p></sec><sec><title>Заключение</title><p>Заключение. Частота саркопении среди людей старше 65 лет, согласно критериям, принятым профессиональными сообществами, варьировала в широких пределах – от 19,8% (FNIN) до 26,5% (EWGSOP2) и 30% (EWGSOP). С возрастом частота саркопении увеличивалась, достигая 52,9% среди лиц старше 85 лет. Определение мышечной силы является более чувствительным методом диагностики саркопении по сравнению с другими функциональными тестами.</p></sec></abstract><trans-abstract xml:lang="en"><p>The prevalence of sarcopenia in different countries of the world has been well studied. However, the criteria of different international professional groups are used to diagnose the disease, which leads to large variability in data on the frequency of sarcopenia in the population. The paper presents the results of studying the frequency of sarcopenia, by using the diagnostic criteria of different working groups. The measures characterizing muscle strength and skeletal muscle function were analyzed; the components that are most important for the diagnosis of sarcopenia were identified in the studied patient group.</p><sec><title>Objective</title><p>Objective: to determine the detection rates of sarcopenia among people aged over 65 years in accordance with the guidelines of different international professional groups and to identify the most significant component for its diagnosis.</p></sec><sec><title>Subjects and methods</title><p>Subjects and methods. The investigation enrolled 230 people older than 65 years (mean age, 74.0±6.5 years) who were followed up in an outpatient setting. Sarcopenia was diagnosed according to the 2010 European Working Group on Sarcopenia in Older People (EWGSOP) criteria. To confirm its diagnosis, the appendicular muscle mass index (AMMI) was calculated using dual-energy X-ray absorptiometry (DXA) on a HOLOGIC QDR Explorer; muscle strength was measured with a Jamar-J00105 handheld dynamometer (Sammons Preston Inc., USA). Muscle function was also examined using the short physical performance battery (SPPB). The frequency of sarcopenia diagnosed by the criteria of the International Working Group on Sarcopenia (IWGS), the Foundation for the National Institutes ofHealth (FNIH), and EWGSOP were comparatively analyzed. </p></sec><sec><title>Results and discussion</title><p>Results and discussion. The frequency of sarcopenia in the sample of people aged over 65 years was the same when using the diagnostic EWGSOP and IWGS criteria (30%) and was significantly higher than when applying the FNIN criteria (19.8%). The frequency of sarcopenia increased from 21.4% at the age of 65–74 years to 52.9% at the age of over 85 years according to the EWGSOP and IWGS criteria and from 16.2% to 29.4%, respectively, by the FNIN criteria. Dynamometry showed that the muscle strength was significantly lower in patients with low muscle mass than in those with normal muscle mass (the average mass was 15.1±5.4 and 18.2±5.4 kg, respectively; p&lt;0.001) among both males and females. The average SPPB scores in the entire sample were low in all the studied groups (7.6±3.1). It was significantly lower in patients with low muscle mass than in people with normal muscle mass (6.9 and 7.9 scores, respectively; p=0.016) as shown mainly by the Tandem test (p=0.0002). No substantial differences in the frequency of sarcopenia were found in different age groups according to the EWGSOP and EWGSOP2 criteria.</p></sec><sec><title>Conclusion</title><p>Conclusion. The frequency of sarcopenia among people aged over 65 years according to the criteria adopted by professional communities varied widely from 19.8% (FNIN) to 26.5% (EWGSOP2) and 30% (EWGSOP). With age, the frequency of sarcopenia increased, reaching 52.9% among people over 85 years of age. Muscle strength measurement versus other functional tests is a more sensitive diagnostic method for sarcopenia. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>пожилой возраст</kwd><kwd>саркопения</kwd><kwd>мышечная сила</kwd><kwd>мышечная масса</kwd><kwd>функция скелетных мышц</kwd></kwd-group><kwd-group xml:lang="en"><kwd>elderly age</kwd><kwd>sarcopenia</kwd><kwd>muscle strength</kwd><kwd>muscle mass</kwd><kwd>skeletal muscle function</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">Cao L, Morley JE, Rosenberg H, et al.
