National Statistics
All reported statistics on this page are based on the National Health Interview Survey, which collects data on a broad range of health topics through personal household interviews with US adults.
From 2016 to 2018, about 1 in 4 US adults (23.7%) about 58.5 million people had doctor-diagnosed arthritis. Arthritis was more common in women (24.7%) compared to men (20.0%), more common among adults with fair/poor health (51.2%) compared to those who have excellent/very good health (15.2%), and less common among adults who meet physical activity recommendations (18.8%) compared to adults who are insufficiently active or inactive (27.0% and 30.9%, respectively). Arthritis prevalence increased with age.1
- Arthritis can have substantial impacts on function. About 44.0% (25.7 million) of the 58.5 million adults with doctor-diagnosed arthritis had limitations in their usual activities due to their arthritis.1

- Arthritis prevalence was highest among adults reporting no leisure time physical activity (30.9%) compared to those who are insufficiently active (27.0%) or who meet physical activity recommendations (18.8%).1
- Arthritis symptoms can be a barrier to physical activity, and inactivity among people with arthritis is associated with conditions such as cardiovascular disease, diabetes, obesity, and functional limitations. However, regular physical activity can be an important way to reduce pain, improve function, and manage symptoms for people with arthritis and other chronic conditions.

- The prevalence of doctor-diagnosed arthritis is expected to increase in the coming decades.
- By 2040, an estimated 78.4 million adults aged 18 years and older (25.9% of the projected total adult population) will have doctor-diagnosed arthritis,2 compared to the 58.5 million adults in 2016–2018 (23.7%).1
