Background: Chronic Hepatitis B (CHB) is an important public health problem in subsaharan African countries and the most serious type of viral hepatitis that causes cirrhosis and liver cancer. Prevention is considered as one of the best strategy to mitigate the problem. Yet, much is not known about predictors of HBV vaccination practice among the general population of Ethiopia specifically Jigjiga town. Objective: To assess predictors of HBV vaccination practice among the general population of Jigjiga town using health belief model (HBM). Method: A community based cross- sectional study was conducted from January 1 to 30, 2019 among 422 individuals aged 18 years and above. Data was collected using pretested structured questionnaire. Data was entered and cleaned using EpiData entry client software and analyzed using SPSS version 25.0. Descriptive and inferential statistics were conducted to present basic statistics. To identify predictors of HBV vaccination practice multiple logistic regression analysis were employed and significance was considered at p< 0.05. Result: The response rate was 405(95.9%), and 401 questionnaires were considered for the analysis. The median age of the respondents was 31years with IQR (28-50 years). Out of the 321 respondents who heard about HB vaccine, 17(5.3%) of them were vaccinated, which indicates low vaccination practice among the respondents. knowledge, (AOR=1.69, 95% CI: 1.1, 2.56), threat (AOR= 1.24, 95% CI: 1.09, 1.4), and cues to action (AOR=1.86, 95% CI: 1.25, 2.76), were identified as independent predictors of HBV vaccination. Conclusion: low vaccination practice was identified among the respondents. Knowledge, threat and cues to action remained independent predictors of HBV vaccination. Health education intervention that gives emphasis on HBM constructs that remained significant is crucial to increase the demand of HB vaccine.
