Risk factors
Risk factors are conditions that increase a person’s chances of developing psoriatic arthritis. These factors are not necessarily a cause of psoriatic arthritis. Common factors often associated with psoriatic arthritis include:
Age & Family history
Although anyone can develop psoriatic arthritis, including children, the condition is more common in adults between 30 and 50 [3].
Having a family member with psoriatic arthritis increases your risk of the disease. Around 40 percent of those who have psoriatic arthritis have a close family member with the disease, such as a parent, sibling, or child. It is not clear why this happens, but researchers have identified [4] certain genetic markers of the disease.
