Epidemic trends of tuberculosis in China from 1990 to 2017: Evidence from the global burden of disease study

Abstract

Purpose: Tuberculosis remains a major public health problem globally, especially in undeveloped countries. This study aimed to evaluate and review the long-term epidemic trends of tuberculosis in China. Methods: Data were extracted from the Global Health Data Exchange. Metrics (prevalence, incidence and mortality) and Joinpoint regression were used to identify the epidemic trends. Results: From 1990 to 2017, decreasing trends in prevalence (average annual percent change, AAPC: −0.5%, 95% CI: −0.6% to −0.5%), incidence (−3.2%, 95% CI: −3.5% to −2.9%), and mortality (−5.7%, 95% CI: −6.2% to −5.3%) of tuberculosis were observed. The incidence and mortality of multidrug-resistant tuberculosis (MDR-TB) decreased with AAPC of −2.3% (−3.1% to −1.4%) and −4.9% (−5.4% to −4.5%), respectively, while the prevalence increased with an AAPC of 1.2% (0.3% to 2.0%). The burden of extensively drug-resistant tuberculosis (XDR-TB) increased with an AAPC of 12.5% (11.9% to 13.2%) in prevalence, 7.6% (6.5% to 8.7%) in incidence, and 4.5% (3.6% to 5.4%) in mortality. The disease burden of tuberculosis increased with age and peaked among those aged over 70. Conclusion: The epidemic of tuberculosis decreased in China, while the disease burden was still challenging to control. MDR-TB and XDR-TB should be emphasized along with the epidemic. It will certainly be a difficult task to achieve the post-2015 global targets by 2025 and 2035.
