Prevalence of stroke symptoms among stroke-free residents: first national data from Lebanon

Int J Stroke. 2015 Oct:10 Suppl A100:83-8. doi: 10.1111/ijs.12563. Epub 2015 Jul 14.

Abstract

Background: Stroke symptoms are common among people without a history of stroke or transient ischemic attack. Reported stroke symptoms may represent stroke episodes that failed to reach the threshold for clinical diagnosis.

Aims: This study aimed to assess in the Lebanese population the prevalence of self-reported stroke symptoms in a stroke- and transient ischemic attack-free population, and the association of these symptoms with major risk factors for stroke.

Methods: We carried out a cross-sectional study using a multistage cluster sample across Lebanon. We interviewed residents aged 40 years and more. Stroke symptoms were assessed using the Questionnaire for Verifying Stroke-Free Status.

Results: We included 1515 individuals (mean age was 57·2 ± 12·4 years, 783 women, 51·7%). Among 1460 participants stroke- and transient ischemic attack-free, 175 had experienced at least one stroke symptom (12·1%, 95% CI 9·9%-14·3%). Arterial hypertension (adjOR 4·37, 95% CI 2·68-7·12), history of heart disease (adjOR 3·34, 95% CI 2·00-5·56), current waterpipe smoking (adjOR 3·88, 95% CI 2·33-6·48), current and former cigarette smoking (adjOR 1·84, 95% CI 1·18-2·87 and adjOR 2·01, 95% CI 1·13-3·5, respectively), psychological distress (adjOR 1·04, 95% CI 1·02-1·05), the Mediterranean diet score (adjOR 0·87, 95% CI 0·76-0·99), and regular physical activity (adjOR 0·45, 95% CI 0·26-0·77) were independently associated with stroke symptoms.

Conclusions: This is the first study conducted in the Middle East, assessing self-reported stroke symptoms among stroke-free residents. Our study showed that almost one in eight residents without a history of stroke or transient ischemic attack has had stroke symptoms. Major vascular risk factors are associated with these symptoms, thus allowing for prevention strategies.
