To analyze the pneumoconiosis mortality change trend, influencing factors and differences between Chinese residents from 2002 to 2021.
Using the Joinpoint model of crude pneumoconiosis mortalityrate and standardized mortalityrate, the annual percentage change (APC) and mean annual percentage change (AAPC) were calculated. The effect of three effects on pneumoconiosis mortality changes was analyzed by the age-period-cohort model.
The urban standardized mortality rate showed an overall downward trend (APC=-0.2%, P>0.05) and increased in rural areas from 2004 to 2021 (APC=7.9%, P<0.001). The age effect showed that both urban and rural pneumoconiosis mortality rate increased with increasing age. The period effect increased with time, and it was different between urban and rural areas, with the risk of urban death decreasing, and the risk of rural death increasing. The cohort effect showed that the risk of death decreased with later birth, and the rural resident birth cohort showed a fluctuating trend.
The increasing effect of age, period and cohort will affect rural pneumoconiosis mortality more than in urban areas.
