What are the risk factors for developing rheumatoid arthritis?
There are several key risk factors associated with the development of rheumatoid arthritis (RA). The primary risk factor is genetics, as individuals with a family history of RA are at higher risk. Other factors include age, with RA being more common among people aged 40 and older, and gender, as women are more likely to develop the condition. Additionally, smoking has been strongly linked to an increased risk of RA, while environmental factors, such as exposure to certain viruses or bacteria, may also play a role. Obesity and a sedentary lifestyle have been associated with a higher risk of developing RA as well. Overall, a combination of genetic, environmental, and lifestyle factors contribute to the risk of developing rheumatoid arthritis.
