13. Physical Activity and Psychosocial Aspects of Arthritis

Author: Patricia Katz, PhD

Publisher: Springer International Publishing

Abstract

The evidence is clear that physical activity and exercise offer health benefits such as improvements in cardiovascular risk factors, reduction of obesity and metabolic syndrome, and reduction in cancer risk. For individuals with arthritis, it also offers reductions in pain and improvements in function. In addition, a great deal of evidence indicates that physical activity improves mood and reduces the risk of depression and cognitive impairment. While the majority of the evidence comes from studies in the general population, a substantial body of literature also comes from studies of individuals with rheumatic diseases. This chapter will review the evidence linking physical activity and exercise to psychological and cognitive well-being and then present information to help practitioners guide patients in initiating physical activity.
