The incidence of abdominal aortic aneurysm (AAA) repairs in Portugal is one of the lowest mentioned in the literature. This phenomenon can be justified either by a low prevalence of the disease or by its low detection rate. To date, the prevalence of the pathology is unknown. The objective of the study was to estimate the prevalence of AAA and its associated risk factors, in men aged ≥65 years and to evaluate the population's disease awareness.
All males aged ≥65 years registered in a Portuguese primary health care unit were invited to participate. The abdominal aorta was measured by ultrasound (inner to inner method). Concomitant risk factors and patient's AAA awareness were also assessed. An aortic diameter >30 mm was considered aneurysmatic.
Nine hundred thirty-three patients were invited for the screening. Of these, 715 participated in the study (participation rate of 76.6%). The AAA prevalence in this sample was 2.1%. Eighty-five percent of the evaluated patients had never heard of the disease before. The mean age of the assessed population was 72.3 years; Multiple logistic regression analysis showed a positive association between AAA and history of smoking (odds ratio [OR] 8.8, P = 0.037) and history of dyslipidemia (OR 9.6, P = 0.035). A negative association was found between diabetes and AAA (OR 0.33, P = 0.045).
The found prevalence shows that a significant number of potentially fatal AAAs remains to be diagnosed in Portugal. These results highlight the need for an effective program of AAA detection in Portugal. The lack of awareness in the Portuguese population for this pathology should also prompt reflexion.
葡萄牙腹主动脉瘤（AAA）修复手术的发生率是文献中提及的最低发生率之一。这种现象的原因可能是该疾病的患病率较低，或者是其检出率较低。迄今为止，该疾病的患病率尚不清楚。本研究的目的是估计65岁及以上男性中AAA的患病率及其相关危险因素，并评估人群对该疾病的知晓情况。
邀请在葡萄牙一家初级医疗保健单位登记的所有65岁及以上男性参与研究。通过超声（内径法）测量腹主动脉。同时评估相关危险因素和患者对AAA的知晓情况。主动脉直径>30mm被视为动脉瘤。
933名患者被邀请参加筛查。其中，715名患者参与了研究（参与率为76.6%）。该样本中AAA的患病率为2.1%。85%的评估患者此前从未听说过这种疾病。评估人群的平均年龄为72.3岁；多因素logistic回归分析显示，AAA与吸烟史（比值比[OR]8.8，P = 0.037）和血脂异常史（OR 9.6，P = 0.035）呈正相关。糖尿病与AAA之间呈负相关（OR 0.33，P = 0.045）。
所发现的患病率表明，葡萄牙仍有大量潜在致命的AAA有待诊断。这些结果凸显了在葡萄牙开展有效的AAA检测项目的必要性。葡萄牙人群对这种疾病缺乏认识也应引起反思。
