Introduction and aim. Data on epidemiology of liver diseases in Brazil is scarce. This study aimed to estimate the burden of chronic viral hepatitis and liver cirrhosis in the country. Materials and methods.The indicator used was disability-adjusted life year (DALY), a sum of years of life lost due to premature mortality (YLL) and years lived with disability (YLD). Liver cirrhosis was analyzed in etiologic categories and cirrhosis of viral origin was considered part of the burden of chronic hepatitis. Results. There were 57,380 DALYs (30.3 per 100,000 inhabitants) attributable to chronic hepatitis B and cirrhosis due to hepatitis B, with 41,262 DALYs in men. Most burden was caused by YLL (47,015 or 24.8/100,000) rather than YLD (10,365 or 5.5/100,000). Chronic hepatitis C and cirrhosis due to hepatitis C were responsible for 207,747 DALYs (109.6/100,000), of which 137,922 were YLL (72.7/100,000) and 69,825 (36.8/100,000) were YLD, with a higher proportion of DALYs in men (73.9%). Cirrhosis due to alcohol or other causes had a total of 536,169 DALYs (1,4% of total DALYs in Brazil), with 418,272 YLL (341,140 in men) and 117,897 YLD (97,965 in men). Highest DALYs' rates occurred at ages 60-69 in chronic hepatitis and at ages 45-59 in cirrhosis due to alcohol or other causes. Conclusion. Chronic viral hepatitis and liver cirrhosis are responsible for a significant burden in Brazil, affecting mainly men and individuals still in their productive years. Most burden is related to non-viral causes of cirrhosis, with a major contribution of alcohol.
