Abstract：Objective To investigate the incidence level and epidemiological characteristics of injury-induced deaths in Quzhou City of Zhejiang Province. Methods The injury-induced death data regarding household-registered residents in Quzhou City from 2010 to 2021 were collected from Zhejiang Chronic Disease Surveillance Information and Management System. We described the death characteristics of whole population and five main types of injuries, and the status of injury-induced deaths through calculating the crude and standardized death rates. Joinpoint regression model was used to analyze the changing trend of the death rates. Results From 2010 to 2021, a total of 23,941 injury-induced death cases were reported in Quzhou City. The crude death rate of injuries was 78.16/100,000, and the standardized death rate was 73.94/100,000. The crude and standardized death rates were higher in males than in females (χ2=776.294, P<0.001). In general, no statistically significant difference was found in the declining trend in the death rates in the past 12 years (Z=-0.501, P>0.05). The average annual decline range of crude death rate of injuries was 0.34%, and the standardized death rate was 1.36%. With the increase of age, the age-specific death rate of injuries in residents showed an obviously upward trend (Z=9.763, P<0.001). Among the five main types of injuries, including road traffic injury, fall, suicide, drowning and poisoning, the death rates were all higher in males than in females (all P<0.001). The death rate of falls displayed a rising trend along with time, while those of the other four types of injuries showed declining trends (all P<0.01). The death rates of the five main types of injuries increased with the increasing age. The injury spectrums of different age groups were inconsistent. Drowning was the major death cause in the age group 0-14 years, accounting for 59.38%. Traffic accident was the major death cause in the age groups 15-44 years and 45-64 years, accounting for 46.95% and 51.25% respectively. Accidental fall was the major death cause in the age group ≥ 65 years, accounting for 59.76%. Conclusion The injury-induced death rates in Quzhou City did not decrease significantly, and were still higher compared with those in other places. According to the characteristics of injury occurrence, the government should conduct targeted health education and interventions based on different groups and different types of injuries.
