To explore the mortality trend and years of life lost due to bladder cancer among residents in Pudong New Area, Shanghai from 2002 to 2022.
The data were derived from the cause-of-death monitoring database of registered residents in Pudong New Area, and the demographic data were provided by the Public Security Bureau of Pudong New Area.The crude mortality rate (CMR), age-standardized mortality rate (ASMR), potential years of life lost (PYLL), potential years of life lost rate (PYLLR), average years of life lost (AYLL), standardized potential years of life lost (SPYLL), standardized potential years of life lost rate (SPYLLR) and probability of premature death were calculated. The Join point software was used to analyze the annual percent change (APC), and the differential analysis method was used to evaluate the influence of population age-structure factors on bladder cancer mortality.
From 2002 to 2022, there were 2 244 deaths from bladder cancer among residents in Pudong New Area, Shanghai. The average annual CMR was 3.81 per 100 000, showing an upward trend (APC=2.24%, Z=4.607, P < 0.001). The average annual Chinese-standardized mortality rate was 1.77 per 100 000, showing an overall downward trend (APC=-1.54%, Z=-3.236, P=0.002). The mortality rate of bladder cancer in men was higher than that in women (ZCMR=24.370, P < 0.001; χ2=1 143.000, P < 0.001). The mortality rate increased with age (χ2=9 324.374, P < 0.001),and the mortality rates in the 60 to >70-year-old group (APC=-3.36%, Z=-3.263, P=0.002) and the 70 to >80-year-old group (APC=-1.99%, Z=-3.229, P=0.015) decreased significantly. The PYLL due to bladder cancer death among residents in Pudong New Area was 9 120 person-years, and the AYLL was 4.06 years per person. The PYLL and AYLL in men were higher than those in women. The population age-structure factor was a risk factor for promoting bladder cancer mortality.
The mortality rate of bladder cancer increases with age, and the death burden of bladder cancer in men is heavier than that in women. Men over 60 years old should be regarded as a high-risk group. The population age-structure factor is the main reason affecting the bladder cancer mortality rate, and active measures should be taken to cope with the impact of aging. The probability of premature death in women shows an upward trend, and the prevention and control of bladder cancer in women need to be strengthened.
