Abstract

Background and Objective: Occupational injuries are considered one of the most critical health, social, and economic risk factors in industrial and developing societies, such as Iran. The long-term trend of these injuries has not been investigated in Hamadan province. Therefore, the present study aimed to assess the trend of mortality and Disability Adjusted Life Years (DALYs) rates due to occupational injuries in Hamedan province from 1990 to 2021. Materials and Methods: In this cross-sectional descriptive study, the trend of changes in the mortality and DALYs due to occupational injuries in Hamedan province over 32 years was investigated using Joinpoint Regression software (version 5.1.0). Results: The DALYs (due to premature death and disability) from occupational injuries in Hamedan province decreased from 496.75 years per thousand population in 1990 to 229.98 years per thousand population in 2021 (the average annual percent changes (AAPC) was -2.40 and 95% confidence interval: -2.60 to -2.30). This decreasing trend in DALY caused by occupational injuries was also evident in men and women (the AAPC in men and women was -2.40% and -1.10%, respectively). Furthermore, the mortality rate due to injuries in both genders decreased from 7.55 cases per 100,000 population in 1990 to 3.46 cases per 100,000 population in 2021 (AAPC was -2.50% (95% CI: -2.60% to -2.40%). Conclusion: Consistent with other studies conducted in Iran and the world, the trend of mortality and DALYs due to occupational injuries in Hamedan province had a decreasing trend.
