The current status and Joinpoint regression analysis of malignant tumor mortality in Qingbaijiang District of Chengdu City from 2010 to 2022
Objective To collect the monitoring data of death causes of malignant tumors in Qingbaijiang District of Chengdu City from 2010 to 2022,and to analyze the death status and the changing trend of mortality rate.Methods The malignant tumor data of Qingbaijiang District of Chengdu City with death time from 2010 to 2022 were derived from the Cause of Death Registration and Reporting Information System of China Disease Prevention and Control System according to household registration.The crude mortality rate,age-standardized mortality rate by Chinese standard population(ASMRC),death rank and other indicators were calculated by SPSS 19.0 to describe the current status of malignant tumors.Chi-square test was used to compare the rates.Average annual percent changes(AAPC)were calculated by Joinpoint 4.8.1 in mortality mode to analysis the changing trend of malignant tumor death.The comparison of AAPCs was conducted by t test,and the test level wasα=0.05.Results There were 12 880 deaths from malignant tumors occurred among residents in Qingbaijiang District of Chengdu City from 2010 to 2022,with a crude mortality rate of 236.40/105 and a ASMRC of 167.90/105.The ASMRC of males were higher than that of females(x2=2077.877,P＜0.001).The top five malignant tumors causing death were lung cancer,esophageal cancer,liver cancer,gastric cancer and colorectal cancer in Qingbaijiang District of Chengdu City.There were no significant differences in the crude death rate(AAPC=1.990％,P=0.112)and ASMRC(AAPC=-1.145％,P=0.417)from 2010 to 2022.The crude death rates for males and females increased by 1.633％(P=0.037)and 1.577％(P=0.037)per year,respectively.The ASMRCs of esophageal cancer(AAPC=-3.131％,P=0.002),liver cancer(AAPC=-5.000％,P=0.001)and gastric cancer(AAPC=-7.179％,P＜0.001)showed a downward trend.The crude mortality rates of lung cancer and colorectal cancer increased by 4.970％(P=0.028)and 5.128％(P=0.024)per year,respectively.Conclusions From 2010 to 2022,the death burden of malignant tumors in Qingbaijiang District of Chengdu City was heavy.Improving residents'health literacy level and early cancer diagnosis and treatment participation is an important way to improve resident'life expectancy.
