Objective: To assess the prevalence of abdominal aortic aneurysm (AAA)
in men with diabetes aged 60 years and over. Design: Prospective scre
ening study. Patients: 303 eligible participants among the first 1000
recruited to a large, community-based study of diabetes. Main outcome
measures: Aortic diameter greater than or equal to 30 mm on screening
ultrasonography, or previous surgery for AAA. Results: AAA was diagnos
ed in three of the 303 men screened, and four others had previously ha
d surgery for AAA. The aorta was not visualised in three obese men. On
ly one AAA required surgery (greater than or equal to 50 mm diameter).
The overall prevalence of AAA was 2.3% (7/300), lower than that repor
ted previously in the general population. Multivariate logistic regres
sion analysis showed statistically significant associations with fasti
ng triglyceride levels, and a history of intermittent claudication. Co
nclusions: Although a small number of men with diabetes aged 60 or mor
e have undiagnosed AAA, the prevalence does not appear to be high enou
gh to warrant targeted ultrasound screening.
