Objective To understand the trend of lung cancer mortality in Nantong from 2005 to 2014, quantitatively estimate related influencing factors, and provide a scientific basis for the prevention and control of lung cancer.
Methods Mortality data of lung cancer in Nantong during 2005-2014 were collected. Crude death rates and age-standardized rates by gender and age were calculated. Percentage change (PC) and annual percentage change (APC) were used for describing temporal trend. Influencing factors of lung cancer mortality were analyzed by the method of difference decomposition.
Results The average crude mortality rate of lung cancer was 53.97/105, and age-standardized mortality rate was 28.23/105. There was a significant upward trend of male lung cancer death with the APC of 3.97% (95%CI: 3.0%-4.6%, P < 0.001), as well as the trend of female with the APC of 4.19% (95%CI: 3.2%-5.1%, P < 0.001) and of whole population with the APC of 3.98% (95%CI: 3.2%-4.5%, P < 0.001). But there were no changes in the standardized mortality rate of male, female, and whole population. The demographic structural contributions to mortality were 97.6% in male, 70.9% in female, and 84.1% in whole population.
Conclusion The crude mortality rate of lung cancer in Nantong is increasing from 2005 to 2014, of which an aging population is a main influencing factor.
