As a part of a program to screen and immunize as many Alaska Natives as possible against hepatitis B infection, hepatitis B virus seromarkers were measured in 52,022 Alaska Natives between 1983 and 1987.
Hepatitis B surface antigen (HBsAg) was found in 1,603 persons (3.1%), and 7,155 persons (13.8%) exhibited hepatitis B virus seropositivity.
While the prevalence of total seropositivity increased with increasing age (p<0.001), the proportion of seropositive persons who were also positive for HBsAg was significantly higher in children under age 5 years than in persons over age 60 (p<0.001).
The total hepatitis B virus seropositivity was significantly higher in males than in females (p<0.001), and a greater proportion of seropositive males than seropositive females had HBsAg (p<0.001).
