  Background: The National Institute for Occupational Safety and Health (NIOSH) maintains surveillance systems for assessing pneumoconiosis mortality and morbidity. Objective: To describe trends in coal workers' pneumoconiosis (CWP) mortality and morbidity, and silicosis and asbestosis mortality, from 1968 to 2000. Methods: Mortality data were drawn from national vital statistics records as either underlying or contributing cause of death using International Classification of Diseases (lCD 8, 9 and 10) codes for CWP, silicosis, and asbestosis. Rates were age-adjusted using the year 2000 U.S. Standard Population. CWP morbidity data were derived from a national health monitoring program for underground coal miners, tabulated by tenure. Results: For CWP, age-adjusted mortality rates decreased from 21.2 deaths/10(6) (2,870 deaths) in 1972 to 4.4 (950 deaths) in 2000. Concomitantly, the CWP prevalence in examined miners has also shown a steep decline over the same period. Silicosis mortality has also decreased, from 8.9 deaths/10(6) (1,157 deaths) in 1968 to 0.7 (33 deaths) in 2000. In contrast, asbestosis mortality has increased from 0.5 deaths/10(6) (77 deaths) in 1968 to 6.9 (1,493 deaths) in 2000. Conclusions: The overall burden of CWP and silicosis in the U.S. has decreased over the last 30 years, reflecting both fewer workers exposed and the efficacy of control measures. In contrast, asbestosis morality has increased, largely a legacy of increased use of asbestos from 1940 through the 1970s. [Description provided by NIOSH]
