This study was designed to determine the epidemiology of stroke in a rural population of Bangladesh.
In a cross-sectional study, we surveyed stroke patients.
The survey was conducted in a rural community of Bangladesh from January 2016 to June 2016. All community members 15 years and older in a surveillance system were included in this study. The Questionnaire for Verifying Stroke-Free Status was used to screen stroke cases at household level which were again examined by the neurologist for confirmatory diagnosis.
The prevalence of stroke was 1.96 (95% confidence interval [CI] 1.69-2.26) per 1000 population. The highest prevalence was 9.65 (95% CI 7.42-12.33) per 1000 population, identified among patients aged 65-79 years. Males had higher prevalence (2.38 per 1000 population) than females (1.55 per 1000 population). Of the 24% of patients who had radiological examination (magnetic resonance imaging and computed tomography scan) reports, 17.2% of stroke cases were ischemic, 4.8% were intracerebral, and about 1.1% were subarachnoid. The ratio of infarction to hemorrhage was 2.91. Approximately 67% of patients were diagnosed as hypertensive, and 37% of patients had elevated blood glucose level. While 15% of patients were found to be overweight or obese, 45% of patients had raised blood cholesterol level. More than 10% of patients reported that they had heart disease before the occurrence of stroke. About 40% of patients had the history of tobacco consumption.
The prevalence of stroke is higher among elderly and male populations. A significant proportion of patients presented with hypertension and/or diabetes.
本研究旨在确定孟加拉国农村人口中风的流行病学情况。
在一项横断面研究中，我们调查了中风患者。
该调查于 2016 年 1 月至 6 月在孟加拉国的一个农村社区进行。所有在监测系统中 15 岁及以上的社区成员都包括在这项研究中。使用验证无中风状态问卷在家庭层面筛查中风病例，然后由神经科医生进行确认诊断。
中风的患病率为每 1000 人 1.96（95%置信区间[CI] 1.69-2.26）。患病率最高的是 65-79 岁的患者，为每 1000 人 9.65（95% CI 7.42-12.33）。男性的患病率高于女性（每 1000 人 2.38 比 1.55）。在接受影像学检查（磁共振成像和计算机断层扫描）报告的 24%的患者中，17.2%的中风病例为缺血性，4.8%为颅内，约 1.1%为蛛网膜下腔出血。梗死与出血的比例为 2.91。约 67%的患者被诊断为高血压，37%的患者血糖水平升高。虽然 15%的患者超重或肥胖，但 45%的患者胆固醇水平升高。超过 10%的患者报告在中风发生前患有心脏病。约 40%的患者有吸烟史。
中风在老年和男性人群中的发病率较高。相当一部分患者伴有高血压和/或糖尿病。
