To describe the decline of tuberculosis (TB) cases among U.S.-born non-Hispanic (NH) black and white Chicago residents.
Data from the National TB Surveillance System was used to analyze trends and characteristics of reported TB cases among U.S.-born NH black and U.S.-born NH white Chicago residents from 1998-2008.
Chicago reported a total of 3,821 TB cases over the 11-year time period. Of these, 1,916 were U.S.-born NH black and 235 were U.S.-born NH white. The proportion of cases attributable to U.S.-born NH blacks was 63% (294/469) in 1998 and 34% in 2008 (72/213). Regression analysis for trends from 2000-2008 revealed a greater than predicted decrease in rates among U.S.-born NH blacks (p<0.05). U.S.-born NH blacks had greater odds than U.S.-born NH whites of HIV infection (OR 1.8), non-injecting drug use (OR 3.0), unemployment (OR 1.7), receiving care from the health department (OR 2.2) and receiving directly observed therapy (OR 3.0).
Despite more TB risk factors in Chicago's U.S.-born black population, there was a narrowing of TB case disparity in Chicago from 1998-2008. Continued focused strategies aimed at controlling TB are needed.
描述美国出生的非西班牙裔（NH）黑人和白人芝加哥居民中结核病（TB）病例的下降情况。
利用国家结核病监测系统的数据，分析1998 - 2008年美国出生的NH黑人及美国出生的NH白人芝加哥居民中报告的结核病病例的趋势和特征。
在这11年期间，芝加哥共报告了3821例结核病病例。其中，1916例为美国出生的NH黑人，235例为美国出生的NH白人。1998年，美国出生的NH黑人所致病例比例为63%（294/469），2008年为34%（72/213）。对2000 - 2008年趋势的回归分析显示，美国出生的NH黑人发病率下降幅度大于预期（p<0.05）。美国出生的NH黑人感染艾滋病毒（比值比1.8）、非注射吸毒（比值比3.0）、失业（比值比1.7）、接受卫生部门护理（比值比2.2）及接受直接观察治疗（比值比3.0）的几率均高于美国出生的NH白人。
尽管芝加哥美国出生的黑人人群中结核病危险因素更多，但1998 - 2008年芝加哥结核病病例差距有所缩小。仍需持续采取针对性策略来控制结核病。
