Abstract:
Objective:To study the epidemiological characteristics of mortality and cause of death composition in patients with coal-burning-borne endemic arsenism in Ankang City, Shaanxi Province.Methods:Mortality data of patients with coal-burning-borne endemic arsenism in Ankang City from 2018 to 2023 were collected from the Shaanxi Provincial Endemic Disease Prevention and Control Information Management Platform and the National Death Cause Information Registration System. Crude and standardized mortality rates, years of life lost (YLL) due to premature death were calculated, and the population and regional distribution characteristics of death cases were analyzed. Causes of death were classified and analyzed according to the International Classification of Diseases (ICD-10) category codes.Results:From 2018 to 2023, a total of 610 patients with coal-burning-borne endemic arsenism died in Ankang City, Shaanxi Province. The average annual crude mortality rate was 5.20/100 000. The average age of death for patients was 77.78 years old, and the mortality rate showed an upward trend with age (χ 2tend = 1 163.82, P < 0.001), with a significant increase in patients over 60 years old. The male to female ratio was 3.18∶1.00 (464/146). Among the seven diseased districts and counties, Langao County had the highest mortality rate. The YLL was 6 241.68 person-years. The top four causes of death among these cases circulatory system diseases, respiratory system diseases, malignant tumors, and injuries differed from those of the entire population in Ankang City, with respiratory system diseases being more prominently ranked. Conclusions:The death cases of coal-burning-borne endemic arsenism in Ankang City are mainly elderly males, and are more common in Langao County. There are various causes of death, coexisting with circulatory system diseases, respiratory system diseases, malignant tumors, and injuries.
