The CDC combined data from the National Health Interview Survey (NHIS) years 2013–2015 Sample Adult Core components to estimate average annual arthritis prevalence in the civilian, non-institutionalized US adult population aged 18 years or older. Overall, an estimated 22.7% (54.4 million) of adults had doctor-diagnosed arthritis, with significantly higher age-adjusted prevalence in women (23.5%) than in men (18.1%). Arthritis prevalence increased with age.1
The impact of arthritis on individuals is significant. About 43.5% (23.7 million) of the 54.4 million adults with doctor-diagnosed arthritis have limitations in their usual activities due to their arthritis.1 Learn more about arthritis-attributable limitations.
The age-adjusted prevalence of arthritis among adults reporting no leisure time physical activity (23.6%) is significantly higher than the prevalence of arthritis among adults who report meeting physical activity recommendations (18.1%).1 Arthritis can be a barrier to physical activity, and inactivity is associated with conditions such as cardiovascular disease, diabetes, obesity, and functional limitations. Learn more about the importance of physical activity on our physical activity for arthritis page.
With the aging of the US population, the prevalence of doctor-diagnosed arthritis is expected to increase in the coming decades. By the year 2040, an estimated 78.4 million (25.9% of the projected total adult population) adults aged 18 years and older will have doctor-diagnosed arthritis,2 compared with the 54.4 million adults in 2013–2015. Two-thirds of those with arthritis will be women. Also by 2040, an estimated 34.6 million adults (43.2% of adults with arthritis or 11.4% of all US adults) will report arthritis-attributable activity limitations.2 These estimates may be conservative, as they do not account for the current trends in obesity, which may contribute to future cases of osteoarthritis.
