Stroke epidemiology in Karabük city Turkey: Community based study

Abstract

Introduction: Stroke has been projected to increase in developing countries like Turkey. Information about the prevalence of stroke may uncover the etiology of stroke and overcome its impact burden. However, data is limited due to a lack of studies based in Turkey and neighboring regions. We aimed to investigate the prevalence and risk factors of stroke in the Turkish city of Karabük and to pave the way for future epidemiological studies in Turkey. Methods: The study was designed as a cross-sectional, door-to-door survey. The questionnaire was completed by a trained team in the presence of the participants according to their answers. Patients who had been diagnosed with stroke prior to the survey were re-examined by a neurologist. Results: 3131 persons who were above 44years old were screened. 129 of them were found to have had a stroke previously. The prevalence rate of stroke above 44years was found to be 4.12% (98% confidence level and ±2% margin of error). 72.1% of stroke patients had hypertension. Male/female ratio was 0.72. Conclusion: This study showed a high prevalence rate of stroke in Karabük Turkey with a low male/female ratio when compared to other studies. Keywords: Stroke, Epidemiology, Turkey, Risk factors
