Change trend analysis of disease burden in laryngeal cancer attributable to smoking in China from 1990 to 2019 / 肿瘤研究与临床

ABSTRACT

Objective:To explore the change trend of disease burden in laryngeal cancer attributable to smoking in China from 1990 to 2019.Methods:Based on data from the 2019 Global Burden of Disease Study database, the changes of death cases, mortality, disability adjusted life years (DALY) and DALY rate of laryngeal cancer attributable to smoking among people with different gender and age in China from 1990 to 2019 were analyzed. Joinpoint software was used to evaluate the annual percentage change (APC) and average annual percentage change (AAPC) of attributable mortality and DALY rate. The change trend of laryngeal cancer death attributable to smoking and DALY was analyzed.Results:From 1990 to 2019, the mortality rate and DALY rate of laryngeal cancer attributable to smoking in China showed an overall upward trend (AAPC of mortality was 1.6%, P < 0.05;AAPC of DALY rate was 1.26%, P < 0.05). In 2019, 75.64% of laryngeal cancer deaths in China were attributable to smoking, with 15 336 attributable deaths, 1.08/100 000 attributable mortality rates, 376 143 person-year attributable DALY and 26.45/100 000 attributable DALY rates, respectively. The population attributable fraction, death number, mortality rate, DALY and DALY rate of laryngeal cancer attributable to smoking in males were higher than those in females. In China, the number of laryngeal cancer deaths and DALY attributable to smoking peaked in the age group of 50-69 years old, and the attributable mortality and DALY rate peaked in the age group of ≥70 years old. Conclusions:The disease burden of laryngeal cancer attributable to smoking is high in China from 1990 to 2019, and there are differences in gender and age.
