Burden of viral hepatitis caused by specific aetiologies in China, 1990–2016: findings from the GBD 2016

Abstract

Background

The aim of this study is to quantify the burden caused by viral hepatitis in China from 1990 to 2016.

Methods

Data from the GBD 2016 study were extracted to calculate incidence, prevalence and disability-adjusted life years (DALYs). Trends in DALYs were assessed in 33 provinces/regions.

Results

From 1990 to 2016, the total incidence of hepatitis decreased by 88.5%. However, the prevalence of hepatitis (counts in thousands), increased by 37.6% from 153,856 (95% UI: 136,047-172,319) in 1990 to 211,721 (95% UI: 179,776-240,981) in 2016, with age-standardized prevalence rates changing slightly. The number and age-standardized rates of prevalence increased by 35.9 and 1.6% for hepatitis B, respectively, and by 81.8 and 30.4% for hepatitis C. Guangxi, Guangdong and Hainan had the highest age-standardized prevalence rates (≥16,500 per 100,000). Tibet, Qinghai and Gansu had the highest age-standardized DALYs rates (≥40 per 100,000). The largest absolute number of DALYs was observed in the 15–49 year age group in 2016. The highest rate of DALYs occurred in males aged 50–69 years and in females aged ≧70 years.

Conclusion

The incidence and DALYs of viral hepatitis decreased dramatically from 1990 to 2016. However, the prevalence still remains at a high level, which may result in heavy burdens in the future.
