Purpose: Ethiopia is grouped with countries with no national strategy for surveillance of viral hepatitis. Hence, data on hepatitis B virus (HBV) infection in the general population are limited. The aim of this study was to estimate the prevalence and associated factors of HBV infection among adults in Southwest Ethiopia.
Materials and Methods: A community-based cross-sectional study was conducted in Southwest Ethiopia, from November 1, 2017–January 30, 2018. A total of 612 individuals were included in the study using a multistage sampling technique. A structured questionnaire was used to collect data and a whole blood sample was aseptically collected and tested for HBsAg using a commercially available rapid serological test kit. Bivariate and multivariate logistic regression were employed and odds ratio with 95% confidence interval was retrieved. P-value < 0.05 was considered as statistically significant.
Results: Among 612 participants, half of them, 310 (50.7%), were in the age range of 25– 34 years. The mean age of the respondents was 32.5 [SD ± 7.5] years. Seroprevalence of HBsAg among adults was 55/612 (9.0%). Tattooing on gums (AOR=23.9, 95% CI (2.2– 26.3)), tattooing on the body (AOR=6.8, 95% CI (1.1– 43.1)), and contact with a jaundiced person (AOR=20.7, 95% CI (6.7– 63.8)) were significantly associated with seroprevalence of HBsAg.
Conclusion: Hepatitis B virus infection in adults at the community level is highly endemic. Modifiable risk factors such as tattooing on gums, tattooing on body, and contact with a jaundiced person account for the high HBV infection. Hence, behavioral education and communication programs designed to reduce HBV infection need to address these modifiable factors.
