Twenty-four Hour Movement Behaviors and Atherosclerotic Risk

This observational study aims to investigate how 24-hour movement behaviors are associated with atherosclerotic risk in adults with rheumatoid arthritis. These behaviors include physical activity, sedentary behavior, and sleep. The main questions it aims to answer are: * Are 24-hour movement behaviors, both individually and in combination, associated with indicators of atherosclerotic risk in adults with RA? * Do changes in 24-hour movement behaviors over 12 months relate to changes in indicators of atherosclerotic risk? Participants will: * Wear activity monitors (accelerometers) continuously for 7 days to measure physical activity, sedentary behavior, and sleep. * Answer questionnaires about their health and lifestyle. * Undergo cardiovascular assessments, body composition measurements, physical fitness tests, and blood tests to measure lipid and inflammatory profile. * Return 12 months later for follow-up assessments. The researchers hope this study will improve understanding of how daily movement behaviors influence cardiovascular health in people with rheumatoid arthritis. The findings may help inform future recommendations to promote healthier movement behaviors and improve cardiovascular risk management in this population.
