Falls and their association with physical tests, functional capacity, clinical and demographic factors in patients with rheumatoid arthritis

Objective: To evaluate the occurrence of falls reported by rheumatoid arthritis patients and its relation to disease activity, functional capacity and physical fitness. Material and methods: A cross-sectional study constituted by a sample of 97 rheumatoid arthritis patients from the city of Marilia (SP) from 2012 to 2013, were assessed for disease activity. Instruments validated for Brazilian population in order to evaluate physical and functional capacity were used. Data analysis was carried out with descriptive statistics, Spearman correlation and Chi-squared test, considering p < 0.05. Results: 88.7% were female subjects with a mean age of 56 (+/- 11.7) years. The median duration of rheumatoid arthritis was 10 years (P25 = 6 and P75 = 17) and the mean of disease activity was 3.6 (+/- 1.3), what was considered a moderate activity. In the last 12 months 37.1% of patients experienced at least one fall, with a total of 52 episodes, and fear of falling was reported by 74.2% of them, but this was not associated to the occurrence of a fall (x(2) = 1.19, p = 0.27). Gender, number of medications, age, disease activity, duration of rheumatoid arthritis, functional capacity, and physical tests showed no associations with history of falls in the past year. Conclusion: It was observed that the occurrence of falls and the fear of falling are quite common in this population. The occurrence of falls in this sample of rheumatoid arthritis patients bears no relation to disease activity, functional capacity, or physical fitness tests. (C) 2016 Elsevier Editora Ltda.
