What age range is most commonly affected by abdominal aortic aneurysms?

The age range of 60-70 years is most commonly affected by abdominal aortic aneurysms (AAAs) primarily due to the degenerative changes in the vascular system that occur with aging. As people get older, the connective tissues in blood vessels may weaken, making them more prone to dilation and rupture.

Statistical studies indicate that the incidence of AAAs increases significantly after the age of 60, with men being at a higher risk than women. The weakening of the aorta can start to become pronounced during this decade of life, which is why screening programs for AAA often recommend evaluation beginning at age 65 for men, especially those with additional risk factors, such as a history of smoking or high blood pressure.

Younger age ranges, such as 40-50 and 50-60 years, show lower incidences of AAA, and the risk increases further into the 70s and 80s. However, by the time individuals reach 60-70 years, the prevalence peaks, making this age range the most critical for assessing risk and potential intervention regarding abdominal aortic aneurysms.
