Cross-sectional screening identifies prevalence and risk factors of AAA in veterans, suggesting key health implications.

To identify independent risk factors associated with abdominal aortic aneurysm (AAA) and determine its prevalence in certain demographics.
Cross-sectional screening study conducted across 15 Department of Veterans Affairs medical centers
Included 73,451 veterans aged 50 to 79 with no prior history of AAA
Utilized ultrasonographic screening and multiple logistic regression analysis.
Detected AAA of 4.0 cm or larger in 1.4% (1031 participants)
Smoking associated with increased risk (OR 5.57, 95% CI 4.24 to 7.31) accounting for 78% of AAAs
Age, height, coronary artery disease, atherosclerosis, high cholesterol, and hypertension also shown to be independently associated with AAA.

Lederle et al. (1997) studied this question.
