Background: Globally, work-related deaths (injuries and diseases) are a major social and public health problem. Register data on fatal occupational injuries in high-income countries may be considered to have high quality, especially when reporting is mandatory and regulated by law. We aimed to assess the accuracy of work-related injury death statistics in Norway, with reference to the Labour Inspection Authority and three other on-going registration systems (the cause-specific mortality register, the register for governmental compensations, and the register for insurance companies)., Methods: In this register-based study, we used the capture-recapture technique to adjust for undercounting. We investigated whether the capture-recapture method using two or three sources gave a valid estimate of fatal occupational injuries as compared with the number of cases identified in four registers administrated by the Norwegian Labour Inspection Authority, Statistics Norway, the Labour and Welfare Administration, and Finance Norway. The inclusion criteria were fatal unintentional injuries among residents of Norway between 2000 and 2003 that occurred while working for income in private and public land-based industries. We obtained ethical and legal approvals., Results: In a period of four years (2000-2003), the Labour Inspection Authority registered 171 occupational injury deaths among residents employed in land-based industries. Two combinations of data sources gave capture-recapture estimates of 246 [95% CI 216; 279] and 265 [95% CI 234; 299] deaths. In total, 246 cases were identified in the four registration systems, which was 44% higher than the number of deaths registered by the Labour Inspection Authority. The Labour Inspection Authority had the most complete register out of the four registration systems., Conclusions: The capture-recapture method used on two overlapping data sources gave highly valid estimates of the total deaths. We demonstrated the existence of significant weaknesses in the registration systems in a country considered to have high-quality register data., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2022 The Authors.)

Background: This study updates information on mortality and cancer morbidity in a cohort of Norwegian talc workers., Methods: Follow-up was extended with 24 years, covering 1953-2011. Comparisons were made with the general population and between subgroups within the cohort., Results: Standardized mortality ratio for non-malignant respiratory disease (NMRD) was 0.38 (95%CI: 0.18, 0.69) and for diseases of the circulatory system (CVD) 0.98 (95%CI: 0.82, 1.16). A non-significantly increased NMRD risk was observed at high dust exposures. There were no deaths from pneumoconiosis., Conclusions: With the clear limitations of a small cohort, our results do hint at an effect of talc dust on mortality from NMRD other than pneumoconiosis, covered by a strong and persisting healthy worker effect. Also, an effect on CVD mortality, masked by a healthy worker selection into the cohort cannot be ruled out. Excess mortality from pneumoconiosis seen in other studies, may reflect exposure to quartz and, possibly, bias due to comparability problems., (© 2017 Wiley Periodicals, Inc.)
