The prevalence of abdominal aortic aneurysm (AAA) and its risk factors are well known in Western countries but few data are available from low- and middle- income countries. We are not aware of systematically collected population- based data on AAA in the African region. We evaluated the prevalence of AAA in a population- based cardiovascular survey conducted in the Republic of Seychelles in 2004 (Indian Ocean, African region). Among the 353 participants aged 50 to 64 years and screened with ultrasound, the prevalence of AAA was 0.3% (95% CI: 0- 0.9) and the prevalence of ectatic dilatations of the abdominal aorta was 1.5% (95% CI: 0.2- 2.8). The prevalence of AAA in the general population seemed lower in Seychelles than in Western countries, despite a high prevalence in Seychelles of risk factors of AAA, such as smoking (in men), high blood pressure and hypercholesterolaemia.
腹主动脉瘤（AAA）的患病率及其危险因素在西方国家已广为人知，但来自低收入和中等收入国家的数据却很少。我们并不知晓非洲地区有关于AAA的系统收集的基于人群的数据。我们在2004年于塞舌尔共和国（印度洋，非洲地区）开展的一项基于人群的心血管调查中评估了AAA的患病率。在353名年龄在50至64岁且接受超声筛查的参与者中，AAA的患病率为0.3%（95%置信区间：0 - 0.9），腹主动脉扩张的患病率为1.5%（95%置信区间：0.2 - 2.8）。尽管塞舌尔AAA的危险因素如吸烟（男性）、高血压和高胆固醇血症的患病率很高，但塞舌尔普通人群中AAA的患病率似乎低于西方国家。
