Arthritis

Arthritis is more common among adults aged 65 years or older, but people of all ages (including children) can be affected. Nearly two-thirds of people with arthritis are younger than 65. Arthritis is more common among women (26%) than men (19%) in every age group, and it affects members of all racial and ethnic groups. Arthritis is also more common among adults who are obese than among those who are normal weight or underweight.
