[Epidemic trend of tuberculosis in adolescents in China, 2000-2019].

To analyze the epidemic trend of tuberculosis (TB) in adolescents in China from 2000 to 2019. We used data from Global Burden of Disease Study 2019 to describe the epidemic trend of TB. The estimated annual percentage changes (EAPC) of the morbidity and mortality were calculated to assess epidemic trends from 2000 to 2019. In 2019, a total of 37 815.670 TB cases and 213.629 deaths were reported in adolescents in China, the morbidity was 25.938/100 000 and the mortality was 0.147/100 000. The cases and deaths of TB in 2019 decreased by 71.84% and 89.90% respectively compared with 2000. In 2019, the incident case number (21 371.747) was 1.30 times higher in male adolescents than in female adolescents (16 443.923), and was 4.11 times higher in age group 15-19 years (30 420.054) than in age group 10-14 years (7 395.616). From 2000 to 2019, the morbidity (EAPC=-3.95, 95%: -4.34- -3.55) and mortality (EAPC=-9.18, 95%: -9.33- -9.02) of TB in the adolescents showed decreasing trends. The morbidity and mortality of drug-sensitive TB, extensively drug-resistant TB and multidrug-resistant TB all showed decreasing trends. The morbidity and mortality of TB and its subtypes among adolescents in China decreased during 2000-2019. More attention should be paid to male adolescents and adolescents aged 15-19 years due to relatively higher incidence intensity of TB.
