Abstract
BACKGROUND: Previous studies have shown that the risk of tuberculosis (TB) increases dramatically during adolescence. The objective of this article was to analyze the burdens and trends of TB incidence and mortality rates in Asian adolescents and young adults. METHODS: Time series ecological study of TB incidence and mortality rates of adolescents and young adults aged 10-24 years from 1990 to 2019, using data extracted from the Global Burden of Disease website for 5 Asian countries. The annual percentage change was calculated by joinpoint regression analysis to estimate the trends in the age-standardized incidence rate (ASIR) and age-standardized death rate (ASDR). RESULTS: The highest ASIR per 100,000 person-years in 2019 was in Mongolia [74 (95% uncertainty interval (UI), 51 to 105)], while the lowest was in Japan [4 (95% UI, 2 to 6)]. The highest ASDR per 100,000 person-years was in Mongolia [2 (95% UI, 1 to 3)], while the lowest was in Japan [0.009 (95% UI, 0.008 to 0.010)]. As the absolute number of cases and deaths decreased from 1990 to 2019, the ASIRs and ASDRs in all five countries also decreased. CONCLUSIONS: Our finding revealed that although all five countries in Asia experienced descending TB incidence and mortality trend in past three decades, the trends were especially significant in developed countries and varied across geographic regions. This study may be crucial in helping policymakers make decisions and allocate appropriate resources to adolescent TB control strategies.
