Takayasu arteritis most commonly affects which group?

• A. Young women under 40
• B. Men over 60
• C. Children under 12
• D. Women in their 40s

Answer: (A)

Takayasu arteritis is a large-vessel vasculitis that most commonly affects young women, with onset typically before age 40. This demographic pattern is a hallmark of the condition, which often presents as diminished pulses or blood pressure differences in the arms due to involvement of the aorta and its major branches. While it can occur in other groups, the incidence is highest in young women under 40, making them the most likely group. The other options—men over 60, children under 12, or women in their 40s—are less typical presentations.
