Knowledge of Stroke Risk Factors and Signs in Parakou, a Northern City of Benin in West Africa

Introduction: We aimed to determine knowledge of stroke risk factors and signs in an urban population of northern Benin. Methods: A door-to-door purposeful sampling survey was conducted in resident population (age ≥15 years) of the district of Titirou in the city of Parakou (N = 255,478) in Benin between March 15 and July 15, 2016. In-person interviews were conducted with data collection on structured questionnaires with close and open questions, according to standard definitions. Multivariable logistic regression was used to assess predictors of good knowledge, defined by provision of a correct response in pre-defined set of questions on stroke risk factors and warning signs. Results: Of 4,671 participants (mean age 27.7 ± 12.9 years; females 50.6%), only 404 (8.6%) knew at least 1 stroke risk factor. Knowledge level of stroke risk factors (odds ratio, 95% confidence interval) was related to age (1.37, 1.27-1.48), level of education (2.54, 1.73-3.72), and family history of stroke (3.01, 2.08-4.26). Only 230 (4.9%) were able to cite at least 1 stroke symptom, and this knowledge was great with increasing age (1.04, 1.02-1.06), family (3.63, 2.41-5.49) and personal history of stroke (3.71, 1.86-7.42), and high level of education (4.35, 2.68-7.07). Conclusion: Knowledge of stroke risk factors and signs is low in northern Benin. Greater public education and awareness campaigns are required to address the burden of stroke.
