Abstract:
[Purpose]To analyze the trends of mortality and disease burden of gastric cancer among residents aged 30 and above from 2009 to 2023 in Wuxi City of Jiangsu Province and to estimate the age-period-cohort effect.[Methods]The gastric cancer mortality data from 2009 to 2023 were collected from Wuxi Death Registration System,and the crude mortality rate,age-standardized mortality rate,years of life lost(YLL)and YLL rate were calculated.The average annual percen-tage change(AAPC)was calculated with Joinpoint regression to analyze the trends of mortality and YLL rate of gastric cancer.The age-period-cohort model was used to analyze the effect of age,pe-riod and birth cohort on gastric cancer mortality.[Results]From 2009 to 2023,there were 32 348 gastric cancer deaths in Wuxi,the crude mortality rate was 44.24/105,and the age-standard mor-tality rate was 25.10/105,with a total YLL of 681 618.33 person-years.The crude mortality rate,age-standardized mortality rate and YLL rate showed decreasing trends,with AAPC of-1.77％(95％CI:-2.10％～-1.43％),-4.59％(95％CI:-4.97％～-4.20％)and-2.14％(95％CI:-2.56％～-1.74％),respectively.From 2009 to 2023,crude mortality rate,age-tandardized mortality rate,YLL in men were higher than those in women,and the decline rates of all indicators in women were faster than those in men.The age effect showed that the overall risk of gastric cancer death increased with age;the period effect showed a gradual decrease in the mortality risk and death burden of gastric cancer over time;the cohort effect showed that the later born cohort had a lower risk of death and death burden.[Conclusion]From 2009 to 2023,the disease burden of gastric cancer mortality in Wuxi showed a decreasing trend,with age and sex being the primary influencing factors.In the future,emphasis should be placed on gastric cancer screening and early intervention in middle-aged and elderly men.
