Objective  To analyze the incidence and mortality of asthma in China from 1990 to 2019, and to explore the influence of age, period and cohort on the incidence and mortality of asthma. Methods  Using the Global Burden of Disease (GBD) 2019 database, the incidence and mortality of asthma in China from 1990 to 2019 were analyzed, and the time variation trend of age-standardized incidence and mortality was analyzed by using Joinpoint software, and the average annual variation percentage was calculated. The age-period-cohort model was constructed to analyze the influence of age, period and birth cohort on the incidence and mortality trend of asthma. Results  In 2019, the incidence of asthma in China was 264.44/100 000, and the mortality rate was 1.74/100 000. The incidence rate of asthma in males (300.94/100 000) and mortality rate (1.99/100 000) were higher than those in females (226.51/100 000 and 1.49/100 000). From 1990 to 2019, the age-standardized incidence of asthma in China showed a downward trend, but the trend was not statistically significant (P>0. 05), and the age-standardized mortality showed a downward trend, with an average annual decrease of 4.90%, with a statistically significant trend (P<0.05). The results of age effect showed that the incidence of asthma in China showed a downward trend, and the death first showed a downward trend, and then increased in the age group of 55-59. The results of period effect show that the risk of asthma is decreasing, and then it is increasing from 2015 to 2019, and the risk of asthma mortality is decreasing. The results of cohort effect show that the later people are born, the lower the risk of asthma onset and death. The death of asthma is attributed to behavioral risk, high body mass index and tobacco, and the occupational risk tends to decrease. Conclusions From 1990 to 2019, the incidence and mortality of asthma in China showed a decreasing trend, and the incidence and mortality of men were higher than that of women. The risk factors of behavioral risk, high body mass index and tobacco were still on the rise, so corresponding measures should be taken to carry out early screening, early detection, and early treatment for key populations.
