Abstract: (91 Views)
Background and purpose: The COVID-19 pandemic may have influenced the average years of life lost (YLL). This study aimed to analyze trends in mortality and YLL before and after the onset of COVID-19 in northern Iran.
Materials and methods: This cross-sectional study was conducted using data from all recorded deaths in Mazandaran Province. The Cochran–Armitage trend test and the Mann–Whitney test were applied for data analysis, with a significance level set at P < 0.01. All analyses were performed using softwares of Stata version 14, Excel 2013, and SPSS version 23.
Results: The crude death rates during the study period were 424, 419, 432, 474, 575, 603, and 496 per 100,000 population, while the corresponding average YLL were 19.7, 19.3, 18.6, 18.1, 17.2, 17.8, and 17.8, respectively, indicating a decrease in YLL during the peak of the COVID-19 pandemic in this province. The findings also indicated greater vulnerability among the elderly, a decline in deaths due to external causes and traffic accidents, a higher incidence of male deaths, and a greater number of deaths occurring in urban areas.
Conclusion: Although COVID-19 increased all mortality indicators studied, the average number of years of life lost due to premature death decreased and its trend changed during the COVID-19 period in this province. The lower number of years of life lost due to premature death in urban population could be due to greater access to healthcare services. It is recommended that, given the availability of a nationwide system for registering and classifying causes of death, this information capacity be used to monitor relevant events and changes in health indicators in order to continuously monitor and take supportive and compensatory measures in crises such as the coronavirus
