Background Rheumatoid arthritis (RA) patients suffer from periodic flare-ups causing joint swelling, pain and potential bone destruction. In addition, RA patient are at greater risk of cardiovascular disease. Therefore, physical activity (PA) has been identified as an important component of a holistic treatment programme [1]. However, research suggests that RA patients fail to reach the recommended PA levels to gain the associated benefits [2]. PA is typically assessed in the exercise literature with self-report measures or via accelerometery. To our knowledge, little is known about the associations between self-reported and objective PA measures in RA patients. Objectives To describe and compare the self-reported and objectively measured physical activity profiles of RA patients. Secondly, to investigate the associations between self-reported and objectively measured PA levels in RA patients. Methods 68 participants (42 female, 4 missing) wore an accelerometer (Actigraph) for an average of 6±1 days. The International Physical Activity Questionnaire (IPAQ) was also completed in reference to the same targeted time period. The associations between objective/self-reported PA levels were examined on sedentary time/total sitting time, light PA/walking, and moderate, vigorous PA and moderate-to-vigorous PA (MVPA) from both meassurements. Results Self-reported time spent sitting (M=343±141 minutes) was significantly less than objectively measured sedentary time (M=583±98; t=-13.12, p
