Data gathered in the 1977 National Health Interview Survey indicate that stroke continues to be a major health problem in the United States. It affects approximately 2 percent of the civilian noninstitutionalized population over age 20. An examination of the stroke population revealed differences in the prevalence rates by various demographic factors, particularly age. More than 70 percent of the stroke victims were limited in their activities, and about 85 percent of all the victims had been informed of their condition by a physician. Only 62 percent indicated that they were hospitalized for their first stroke, and this finding remained unchanged when only recent strokes were examined. The low hospitalization rate may reflect a lack of information on patients who died during the interval of on those who did not associate their hospitalizations with their strokes.
1977年全国健康访谈调查收集的数据表明，中风在美国仍然是一个主要的健康问题。它影响着20岁以上约2%的非机构化平民人口。对中风人群的调查显示，不同人口因素，特别是年龄的患病率存在差异。超过70%的中风患者活动受限，约85%的患者已被医生告知病情。只有62%的人表示他们首次中风时住院治疗，仅考察近期中风时这一发现保持不变。低住院率可能反映了在中风间隔期死亡患者或那些没有将住院与中风联系起来的患者信息不足。
