Incidence, Mortality, and Burden of Hepatitis B and C and Geographical Distribution in Iran during 2008-2015
Background: This study aimed at estimating the incidence, mortality, and burden of Hepatitis B (HBV) and Hepatitis C (HCV) viruses and their trends from 2008 to 2015.
Methods: The Disability Adjusted Life Year (DALYs) index was applied to calculate the burden of the diseases by age, sex, time, and locations. The incidence and demographic data were obtained from HBV and HCV surveillance system, and the data on natural history was extracted from the cohort studies; moreover, the data on the standard life expectancy was obtained from the Iranian life table 2016. The two values of 0.03 and 21.5 yr were set as the discount rate and mean standard duration of the disease for both types of hepatitis.
Results: The burden of HBV decreased from 13735 to 78277.6 yr, but there was an increase in the burden of HCV from 5174 to 14395 yr over the studied period. The burden of both types of hepatitis was higher among males than females. The incidence of HBV increased from 46611 to 22996 cases, and the incidence of HCV increased from 1210 to 3939 cases. The HBV decreased from 1925 to 1394 cases; however, the number of deaths caused by HCV increased from 197 to 583 cases over the studied period. The share of YLLs raised from 5% to 10% for HBV whereas it changed from 23% to 62% for HCV over the studied years. Tehran, Khorasan Razavi, and Golestan had the highest and Chaharmahal and Bakhtiari, Kurdistan, and Kermanshah had the lowest adjusted burden of HBV per 1000 population.
Conclusion: Although the incidence, mortality, and burden of HBV declined over the eight studied years, these values increased dramatically for HCV.
