В исследование включены 68 женщин (медиана возраста – 59 [54; 63] лет) в постменопаузе с РА. Всем пациенткам проводилась двуэнергетическая рентгеновская абсорбциометрия (Dual energy X-ray Absorptiometry, DXA) для определения МПК и состава тела.</p></sec><sec><title>Результаты</title><p>Результаты. У 33 (48,5%) женщин выявлена остеопения, у 17 (25,0%) – остеопороз (ОП). Низкая мышечная масса обнаружена у 10 (14,7%) пациенток. Установлены позитивные корреляционные связи между МПК различных отделов скелета и массой тела, жировой и мышечной массой туловища и общим содержанием мышечной массы. В ходе многофакторного линейного регрессионного анализа установлено влияние общего содержания мышечной массы на МПК поясничного отдела позвоночника (β=0,638; р=0,001) и проксимального отдела бедра в целом (β=0,473; р=0,008), мышечной массы конечностей, оцененной с помощью аппендикулярного мышечного индекса, – на МПК шейки бедра (β=0,360; р=0,014).</p></sec><sec><title>Заключение</title><p>Заключение. У 73,5% пациенток с РА выявлена сниженная МПК, у 14,7% – низкая мышечная масса. Обнаруженная значимая взаимосвязь между мышечным компонентом состава тела и МПК поясничного отдела позвоночника и проксимального отдела бедра указывает на важность выявления и коррекции низкой мышечной массы, а также профилактики ее снижения с целью предотвращения потерь МПК и остеопоротических переломов.</p></sec></abstract><trans-abstract xml:lang="en"><p>Aim – to study the relationship between body composition and bone mineral density (BMD) in postmenopausal women with rheumatoid arthritis (RA).</p><sec><title>Material and methods</title><p>Material and methods. 68 postmenopausal women, median age 59 [54; 63] years, with RA were included in the study. Bone mineral density (BMD) and body composition were assessed with dual energy X-ray absorptiometry.</p></sec><sec><title>Results</title><p>Results. 33 (48.5%) women had osteopenia, and 17 (25.0%) – osteoporosis (OP). Low lean muscle mass was found in 10 (14.7%) patients. There were positive correlations between different areal BMD and body weight, trunk fat, trunk lean muscle mass and total lean muscle mass. In the multivariate linear regression analysis total lean muscle mass was associated with BMD of lumbar spine (β=0.638; p=0.001) and total hip (β=0.473; p=0.008), and appendicular lean muscle mass, estimated using the appendicular muscle index, with femoral neck BMD (β=0.360; p=0.014).</p></sec><sec><title>Conclusion</title><p>Conclusion. 73.5% of patients with RA had a reduced BMD, and 14.7% women – low muscle mass. The revealed significant association between the lean muscle mass and BMD of lumbar spine and proximal femur indicates the importance of detecting and correcting low lean muscle mass, as well as preventing its decline in order to prevent loss of BMD and osteoporotic fractures.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ревматоидный артрит</kwd><kwd>минеральная плотность кости</kwd><kwd>состав тела</kwd><kwd>саркопения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rheumatoid arthritis</kwd><kwd>bone mineral density</kwd><kwd>body composition</kwd><kwd>sarcopenia</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках научной темы «Разработка методов комплексной терапии заболеваний костно-мышечной системы» (Рег. № НИОКТР АААА-А19-119021190150-6), утвержденной Ученым советом ФГБНУ НИИР им.
