Worum geht es in dieser Arbeit?

The aim – to study the features of geriatric status in patients with rheumatoid arthritis (RA) aged ≥65 years. Materials and methods . The EUCALYPT study enrolled 4308 people (30% men) aged 65 to 107 years (median 78 years) residing in 11 regions of the Russian Federation. A comprehensive geriatric assessment, consisting of a survey using a specially developed questionnaire and an objective examination, was performed for all participants. The presence of RA in the subjects was determined based on records in their medical charts. Information on the presence or absence of RA was available for 4295 (99.7%) patients. Results. The prevalence of RA among all patients was 6.9%, including 7.6% among individuals aged 65–74 years, 7.5% among those aged 75–84 years, and 5.2% among those aged ≥85 years (p=0.026). The prevalence of RA in women was 1.4 times higher than in men (7.6% vs. 5.3%; p=0.005). Univariate regression analysis showed that with each additional year of age the odds of having RA decreased by 2% (odds ratio ( R) – 0.98; 95% confidence interval (95% CI): 0.97–0.997; p=0.019), whereas women had 49% higher odds of having RA (OR=1.49; 95% CI: 1.12–1.97; p=0.005). Compared with patients without RA, the geriatric status of patients with RA was somewhat worse, as they had a higher prevalence of a number of geriatric syndromes (GS): chronic pain (97.6% vs. 86.4%; p
