Abstract

Background

This study had the following 3 goals: (i) to assess the prevalence of peripheral arterial disease (PAD) in a Nova Scotian population; (ii) to evaluate the validity of the Edinburgh Claudication Questionnaire (ECQ) in a Nova Scotian context; and (iii) to evaluate Nova Scotian public knowledge about PAD.

Methods

Participants were recruited from 8 sites across Nova Scotia. In 2022, they were recruited at Heartland Tour (HLT) sites—a provincial health-promotion campaign. In 2023, they were recruited in communities coinciding with HLT sites (public [PUB]). Participants completed a demographics questionnaire, ECQ, and had an ankle–brachial index (ABI) measurement. An ABI of < 0.9 was considered positive for presence of PAD.

Results

A total of 417 participants were recruited, 263 from HLT, and 154 from PUB. A total of 398 participants had ABI scores resulting in a PAD prevalence of 2.81% (249 participants) in the HLT group, and 5.37% (149 participants) in the PUB group. A total of 394 participants had both ABI and ECQ scores, with a found sensitivity of 6.67% (confidence interval 0.17%-31.95%) and specificity of 97.63% (confidence interval 95.54%-98.91%). A total of 75% of participants (311 of 417) did not have prior knowledge of PAD.

Conclusions

The PAD prevalences in both cohorts were higher than anticipated, with the PUB cohort being more than double the national average. This finding raises the following question: should specific PAD primary and/or secondary prevention strategies be targeted within the province? Our study demonstrated that a public-awareness campaign would be highly impactful, owing to a low level of awareness of PAD within both cohorts, and that the ECQ was not an effective screening tool when used on the Nova Scotian population.

新斯科舍省的外周动脉疾病:患病率增加、公众认知度低、爱丁堡跛行问卷敏感性差
背景这项研究有以下 3 个目标:(i) 评估外周动脉疾病 (PAD) 在新斯科舍省人口中的患病率;(ii) 评估爱丁堡跛行问卷 (ECQ) 在新斯科舍省环境中的有效性;(iii) 评估新斯科舍省公众对 PAD 的了解程度。2022 年,他们在心脏地带之旅 (HLT) 站点招募,这是一项省级健康推广活动。2023 年,在与 HLT 站点(公共场所 [PUB])重合的社区招募参与者。参与者填写了人口统计学问卷、ECQ,并进行了踝肱指数(ABI)测量。结果共招募了 417 名参与者,其中 263 人来自 HLT,154 人来自 PUB。共有 398 名参与者进行了 ABI 评分,结果 HLT 组的 PAD 患病率为 2.81%(249 人),PUB 组的 PAD 患病率为 5.37%(149 人)。共有 394 名参与者同时拥有 ABI 和 ECQ 分数,灵敏度为 6.67%(置信区间为 0.17%-31.95%),特异度为 97.63%(置信区间为 95.54%-98.91%)。共有 75% 的参与者(417 人中有 311 人)事先并不了解 PAD。这一发现提出了以下问题:是否应在全省范围内采取特定的 PAD 一级和/或二级预防策略?我们的研究表明,由于两个队列中的人群对 PAD 的认识水平较低,因此公众宣传活动会产生很大的影响,而且在新斯科舍省人群中使用 ECQ 并不是一种有效的筛查工具。
