Risk factors

Factors that may increase your risk of rheumatoid arthritis include:

• Your sex. Women are more likely than men to develop rheumatoid arthritis.
• Age. Rheumatoid arthritis can occur at any age, but it most commonly begins in middle age.
• Family history. If a member of your family has rheumatoid arthritis, you may have an increased risk of the disease.
• Smoking. Cigarette smoking increases your risk of developing rheumatoid arthritis, particularly if you have a genetic predisposition for developing the disease. Smoking also appears to be associated with greater disease severity.
• Excess weight. People who are overweight appear to be at a somewhat higher risk of developing rheumatoid arthritis.
