Previous studies have reported a higher prevalence of inguinal hernia in patients with abdominal aortic aneurysm (AAA). The aim of this study was to explore the association between inguinal hernia and AAA in a large population-based cohort of men who had screening for AAA.
A total of 18,331 men aged 65-76 years had ultrasound screening for AAA in the Central Region of Denmark from 2008 to 2010. The Danish National Patient Registry was interrogated, and screened men registered with an inguinal hernia from 1977 to 2011 were identified. The association between inguinal hernia and AAA was assessed by multiple logistic regression analysis.
The prevalence of AAA was 3.3 per cent (601 of 18,331). A total of 2936 (16.0 per cent) of the 18,331 patients were registered with a diagnosis of inguinal hernia or hernia repair. Inguinal hernia was not associated with AAA: crude odds ratio (OR) 0.86 (95 per cent confidence interval 0.68 to 1.09) and adjusted OR 0.94 (0.75 to 1.20).
In contrast to smaller patient-based studies, this large population-based study found no association between inguinal hernia and AAA.
先前的研究报告称，在腹主动脉瘤（AAA）患者中，腹股沟疝的患病率较高。本研究旨在探讨在接受 AAA 筛查的 65-76 岁男性大型人群队列中，腹股沟疝与 AAA 之间的关联。
2008 年至 2010 年，丹麦中部地区对 18331 名 65-76 岁男性进行了 AAA 超声筛查。丹麦国家患者登记处进行了查询，并确定了自 1977 年至 2011 年登记有腹股沟疝的筛查男性。通过多因素逻辑回归分析评估腹股沟疝与 AAA 之间的关联。
AAA 的患病率为 3.3%（601/18331）。18331 名患者中，共有 2936 名（16.0%）被诊断为腹股沟疝或疝修补术。腹股沟疝与 AAA 无关：粗比值比（OR）为 0.86（95%置信区间 0.68 至 1.09）和调整后的 OR 为 0.94（0.75 至 1.20）。
与较小的基于患者的研究相比，这项大型基于人群的研究未发现腹股沟疝与 AAA 之间存在关联。
