INTRODUCTION: despite the existence of a preventive vaccine against hepatitis B viral (HBV) infection, approximately 250 million people are infected with the virus worldwide. This study aimed at evaluating the level of knowledge, attitude and seropositivity of the disease among apparently healthy, potential blood donors at the blood service of the Bamenda Regional Hospital Blood Bank.
METHODS: a cross-sectional study was carried out from March to May 2019 among 250 blood donors. Following screening for hepatitis B surface antigen (HBsAg) using the one-step HBsAg test strip, information on the level of knowledge and attitude towards the infection was obtained using a self-administered questionnaire. The correlation analysis was done to assess relationships between selected factors and knowledge of hepatitis B, p-value of 0.05 was considered as statistical significance.
RESULTS: the seropositivity of HBV was 6.4% (n = 16). Overall, 46.8% (n = 19) of the study participants had adequate knowledge while 76.3% (n = 31) had a positive attitude toward the disease. The highest seropositivity was observed in singles (7.1%; n = 13), primary school leavers (14.3%; n = 5), unskilled laborers (14.5%; n = 8) and replacement donors (9.33%; n = 7). The probability of being hepatitis B seropositive was higher in males, students (aOR: 8.8, 95% CI 0.7-96.1; p = 0.046) and those who had attained higher education (aOR: 3.2, 95% CI 0.8-12.7; p = 0.016). Independent factors responsible for higher odds of inadequate knowledge were being a male and attaining secondary education. On the contrary, students (aOR: 0.3, 95% CI 0.1-0.8; p = 0.012) and those with a history of blood donation (aOR: 0.5, 95% CI 0.2-0.9; p = 0.042) recorded lower odds of inadequate knowledge.
CONCLUSION: the prevalence of hepatitis B among blood donors in this blood service is in the high intermediate category. Overall, the level of knowledge on this infection among these blood donors is average. These findings suggest that health education on HBV infection should be provided to the public as a major strategy to curb the infection.
