Trends of hepatitis B and hepatitis C mortality in Canada, 1979-1997

Mortality data from Statistics Canada were analyzed to measure the temporal trends and burden of illness attributed to viral hepatitis in Canada. Anal ysis of age-standardized mortality rates from 1979 to 1997 showed an increa sing trend in mortality for both hepatitis B and non-A, non-B hepatitis (NA NBH), most of which are attributed to hepatitis C infections. Hepatitis B a nd NANBH age-standardized mortality rates increased respectively, from 0.03 and 0.12 deaths per 100,000 population in 1979 to 0.26 and 0.41 deaths per 100,000 in 1997. Male mortality rates Were consistently higher than female for both diseases. Among deaths from chronic liver disease, over 1,000 dea ths were estimated to have been caused by hepatitis B and hepatitis C annua lly. Although the hepatitis B or NANBH recorded deaths largely underestimat e the true burden of HBV and, HCV in Canada, the temporal trends are useful as they reflect changes in die impact of both diseases.
