To analyze the mortality trend of colorectal cancerr from 1990 to 2019, and to provider evidence for formulating prevention and treatment policies for colorectal cancer. Methods The; Joinpoint regression model was used to analyze the trend of colorectal cancer mortality. The; age - period - cohort (APC) model was used to estimate; the: age, period, and cohort elfects on the: risk of colorectal career mortality. Results From 1990 to 2019, the: standardized mortality rate: of colorectal cancer in China, female: anel nude: showexl a flue-tuating increase: trend, and the: average: annual percentage: change: was 1.049%, 0. 158%, and 1.712%, respectively. APC model showed that the: mortality risk of colorectal cancer in male: anel female: residents aged 90 to 94 years was 590 and 281 times higher than that in 10 to 14 years old residents, respectively. In terrnrs of period elfect, compare:! with 1990 - 1994, the: risk of death from colorectal cancer in mem and women in 2015 -2019 was 3. 36 times anel 1.90 times respectively; in terms of cohort elfect, the: mortality risk of colorectal cancer for mem and women horn in 1900 - 1904 was 68. 91 times and 45. 40 times higher than that horn in 2010 -2014, respectively. Conclusion The: mortality rate: of edorcctal eranccr is on the: increuse:. Colorectal canecr mortality is higher in males than in females. The: risk of death from colorectal eranccr ine:re:ases with age: and period. The: elderly are: the: key monitoring group; the: later the: residents are: horn, the: lower the: risk of death.
