Abdominal aortic aneurysm (AAA) affects more which sex?

• A. Equal
• B. Cannot determine
• C. Men
• D. Women

Answer: (C)

Abdominal aortic aneurysm is more common in men, especially as people age. Population data show men have a higher prevalence of AAA than women, with the difference most evident in older age groups (often 65 and up). Factors such as higher historical rates of smoking and atherosclerotic disease in men contribute to weakening of the abdominal aortic wall. Hormonal influences may offer some protection to premenopausal women, but overall the risk remains higher in men across the typical screening ages. So, the sex most affected is men.
