title: Relationship between hepatitis B surface antigen prevalence, per capita alcohol consumption and primary liver cancer death rate in 30 countries.
abstract: The relationships between the prevalence of hepatitis B surface antigen (HBsAg), mean annual per capita alcohol consumption and primary liver cancer (PLC) death rates were explored in 30 countries. HBsAg prevalence was associated, significantly, with the logarithm of the primary liver cancer death rate (simple correlation coefficient = 0.44, p less than 0.05). This significant association increased following adjustment for a country's mean annual per capita alcohol consumption (partial correlation coefficient = 0.53, p less than 0.01). A logarithmic linear relationship was also found between per capita alcohol consumption and the primary liver cancer death rate after adjustment for the country's prevalence of HBsAg (partial correlation coefficient = 0.38, p less than 0.05). Results from both correlation and regression analyses showed that prevalence of HBsAg was more significantly associated with PLC death rates than was alcohol consumption. However, these two variables were independently related to the PLC death rate in a stepwise multiple regression model. We could not demonstrate an interaction between the two variables. These findings are consistent with the prevailing view that chronic hepatitis B infection is the major factor in the most common form of primary liver cell cancer, hepatocellular carcinoma. In addition, they support the notion that alcohol consumption contributes significantly and independently, although probably to a lesser extent than hepatitis B, to deaths from that disease.
