Back Arthritis in Missouri Arthritis in back is one of Missouri's most prevalent chronic health problems, affecting approximately 1.5 million residents 18 years of age and older. It costs approximately $1.3 billion annually in Missouri and is a leading cause of disability. Contrary to the popular belief that arthritis afflicts only the elderly, an estimated 41.5% of Missouri adults between the ages of 35 and 64 suffer from this disabling condition. 37% of Central Missouri adults reported being told by a doctor they have arthritis (Dr. Dx) and/or indicated they had chronic joint symptoms (CJS) - pain, stiffness, and swelling - suggestive of undiagnosed arthritis. Central Missouri adults with arthritis reported higher mean numbers of days in the past month that their physical and mental health were not good. Additionally, they reported more days when physical or mental health prevented their usual activities than those without arthritis. Approximately two-thirds of Central Missouri adults with arthritis are currently not receiving treatment by a doctor for their arthritis. Additionally, approximately one-quarter of adults with arthritis have not had a routine check-up in the past year. Early diagnosis, treatment, and regular care by a doctor in addition to regular physical activity, weight management, and selfmanagement of arthritis are essential for maximizing health outcomes and quality of life.
