| Abstract |
Data on 109 patients who had level-4 pneumoconiosis according to the Japanese grading scheme and who died between 1948 and 1993 were analyzed. All had undergone long-term treatment. The mean age at death increased from 48.0±3.8 years in the 1940s to 75.2±5.7 years in the 1990s. The mean age at which the patients were diagnosed as requiring medical treatment also increased, from 46.7±3.9 to 58.3±10.1 years. The same tendency is found among those with other levels of pneumoconiosis. The later onset and increased life expectancy in more recent years are probably due to (1) reduced dust exposure thanks to improvements in the work environment and (2) improvements in occupational health management and the workers' compensation system. |
