ABSTRACT
OBJECTIVE:
To estimate the age-specific seroprevalence of hepatitis B surface antigen (HBsAg) in children upto 14 years of age.METHODS:
Equal number (115 each) of apparently healthy children of both sexes of different age groups i.e. < 1, 1-4, 5-9 and 10-14 years, attending pediatric outpatient services and Well Baby Clinic of the hospital were tested for HBsAg using ELISA test. Positive results were confirmed by a second ELISA.RESULTS:
Overall 4.35% (95%CI, 2.44 - 6.25) of the 460 children tested were HBsAg positive. The prevalence rate was the highest (6.09%) in the 1-4 year age category. In the < 1, 5-9 and 10-14 year age groups it was 4.35%, 4.35% and 2.61% respectively. The overall male to female ratio was 2.11, with no significant difference in seropositivity rates (P = 0.816).The difference in the prevalence rates between the rural (4.84%) and urban populations (3.77%) was also statistically insignificant (P = 0.577).CONCLUSION:
Average HBsAg positivity in the pediatric population in this region is 4.35% (95%CI, 2.44 - 6.25). The prevalence progressively increases and peaks in the 1- 4 years age group. It is least in 10-14 years age group.
