本研究试图确定1980年在亚拉巴马南部地区中风并住院的所有人。收集了疾病发作、临床病程、实验室检查结果、危险因素史和结局的数据。年龄调整后的首次卒中发病率为白人109/100，000，黑人208/100，000。黑人的特异性发病率高于白人，黑人女性的发病率最高。按卒中类型划分的病例分布为：动脉粥样硬化性血栓形成（6%）、栓塞性（26%）、腔隙性（13%）、起源不明的梗死（40%）、实质性出血（8%）、蛛网膜下腔出血（6%）和类型不明（1%）。黑人有更高的发病率为脑卒中，黑人女性有最高的发病率为腔隙性脑卒中。本系列研究的总体卒中发病率并没有显著高于先前的人群研究，这表明亚拉巴马南部并不是美国东南部所谓的“卒中带”地区的一部分。
This study has attempted to identify all persons from an area of southern Alabama who had a stroke in 1980 and were hospitalized. Data were gathered on disease onset, clinical course, laboratory results, history of risk factors, and outcome. The age-adjusted incidence rates for initial stroke were 109 per 100,000 for whites and 208 per 100,000 for blacks. Age-specific rates were higher in blacks than whites, and highest for black females. The distribution of cases by type of stroke was: atherothrombotic (6%), embolic (26%), lacunar (13%), infarction of unspecified origin (40%), parenchymatous hemorrhage (8%), subarachnoid hemorrhage (6%), and unidentified type (1%). Blacks had higher incidence rates for hemorrhages, and black females had the highest incidence rate for lacunar stroke. The overall stroke incidence rates in this series were not significantly higher than those from prior population studies, suggesting that southern Alabama is not part of the so-called "Stroke Belt" area of the southeastern United States.
