中国居民2004--2020年意外中毒死亡趋势分析.

Objective To understand the death situation and changing trend of accidental poisoning among Chinese residents from 2004 to 2020, and to provide scientific basis for formulating prevention strategies of accidental poisoning. Methods The data of accidental poisoning deaths of Chinese residents in the national death cause surveillance system from 2004 to 2020 were collected. The annual percent change (APC) and average annual percent change (AAPC) were calculated by statistical software Joinpoint 4.9.0; and the change trend of standardized mortality was analyzed. Results There was no obvious turning point in the overall downward trend of the standardized mortality rate of accidental poisoning in Chinese residents (AAPC=- 3.1%, P < 0.05). The crude death rate of accidental poisoning in males was 2.15 to 2.61 times higher than that in females. The standardized mortality rate of urban residents decreased from 339/100 000 in 2004 to 1.37/100 000 in 2020 (AAPC=- 4.3%, P < 0.05), and that in rural areas decreased from 3.94/100 000 in 2004 to 2.84/100 000 in 2020 (AAPC=-2.6%!, P < 0.05). The standardized mortality rate of accidental poisoning in residents aged 4 years old decreased from 0,08/100 000 in 2004 to 0.02/100 000 in 2020 (AAPC二--1.7%, P < 0.05). The standardized mortality rate of accidental poisoning in residents aged 44 years old decreased from L40/100 000 in 2004 to 0.90/100 000 in 2020 (AAPC =-1.7%, P < 0.05). The standardized mortality rate of accidental poisoning among residents over 65 years old decreased from 1.47/100 000 in 2004 to 0.79/100 000 in 2020 (AAPC =-3,7%, P < 0.05). The standardized mortality rate of accidental poisoning in the eastern region decreased from 3,61/100 000 in 2004 to 2.01/100 000 in 2020 (AAPC=-5.6%, P < 0.05). The standardized mortality rate of accidental poisoning in the central region decreased from 4.25/100 000 in 2004 to 235/100 000 in 2020 (AAPC=-3.1%, P < 0.05). Although it decreased in the western region, it was not statistically significant. Condusion The standardized mortality rate of accidental poisoning among Chinese residents decreased slightly from 2004 to 2020, and there were differences among different genders, regions, places of residence and age groups, among which the elderly and residents in the western region were the high-risk groups of accidental poisoning deaths.
