Magnitude, geographic, and ethnic variation in trends in stroke within the United States require updating for health services and health disparities research.
Data for stroke were analyzed from the US mortality files for 1999 to 2007. Age-adjusted death rates were computed for non-Hispanic African Americans and European Americans aged ≥45 years.
Between 1999 and 2007, the age-adjusted death rate per 100,000 for stroke declined both in African Americans and in European Americans of both genders. Among African American females, European American females, and European American males, rates declined by at least 2% annually in every division. Among African American males, rates declined little in the East and West South Central divisions where disparities in trends by urbanization level were found.
Between 1999 and 2007, the rate of decline in stroke mortality varied by geographic region and ethnic group.
美国范围内的卒中趋势在幅度、地域和种族上存在差异，这需要更新数据以用于医疗服务和健康差异研究。
对 1999 年至 2007 年美国死亡率文件中的卒中数据进行了分析。对≥45 岁的非西班牙裔非裔美国人和欧洲裔美国人进行了年龄调整后的死亡率计算。
1999 年至 2007 年间，非裔美国人和两性的欧洲裔美国人的年龄调整后卒中死亡率均有所下降。在非裔美国女性、欧洲裔美国女性和欧洲裔美国男性中，各分区的卒中死亡率每年至少下降 2%。在非洲裔美国男性中，在城市水平的卒中趋势差异明显的东和中南部西部分区，卒中死亡率下降幅度较小。
1999 年至 2007 年间，卒中死亡率的下降率因地理位置和种族群体而异。
