A risk factor is something that increases your likelihood of getting a disease or condition.
It is possible to develop rheumatoid arthritis (RA) with or without the risk factors listed below. However, the more risk factors you have, the greater your likelihood of developing RA. If you have a number of risk factors, ask your doctor what you can do to reduce your risk.
RA can develop at any age, but it usually appears between 30 and 50 years of age. RA is more common in women, and it appears later in life for men.
Other factors that may increase your chance of RA include:
