Changing trajectory of lung cancer mortality in Chinese residents 30 years old and above, 2013 – 2018

Abstract

Objective To analyze changing trajectory of lung cancer mortality among Chinese residents aged 30 years and above from 2013 to 2018 and to provide evidences for developing strategies on lung cancer treatment and prevention. Methods From cause-of-death data in the National Disease Surveillance Point system, we extracted the data on all lung cancer deaths at ages of 30 and above (n = 588 245) registered from 2013 through 2018 at 605 surveillance sites in 31 provincial level regions across China. The population census data of 2010 was used in calculation of standardized mortality rate (SMR). Latent variable growth model was adopted to analyze gender-, age-, and region-specific changing trajectory of lung cancer mortality. Results For years of 2013 – 2018, the annual crude mortality rates (1/100 000) of lung cancer were 40.2, 40.0, 44.8, 44.9, 45.4, and 46.5 for the Chinese residents aged 30 years and above, respectively and the corresponding SMRs (1/100 000) were 35.4, 37.2, 38.8, 36.5, 36.6, and 36.1, with an up-down trend (χ2trend = 3.42, P Conclusion There are different changing trajectories of lung cancer mortality between male and female residents in China. Identifying gender-, age-, and region-specific changing trajectory of lung cancer mortality is meaningful for developing targeted measures for lung cancer prevention and control.
