Seroprevalence and factors associated with Hepatitis B virus infection among students in two senior high schools in the Krachi Nchumuru district in Ghana-A cross sectional study

Abstract

Background There is paucity of hepatitis B virus (HBV) data among student populations although Ghana is HBV endemic. Screening and identification of factors associated with HBV transmission in schools will support the intervention in the elimination of the virus by 2030. This study assessed the seroprevalence and factors associated with HBV among students in two Senior High Schools in the Krachi Nchumuru District in Ghana. Methods Through cross-sectional design and simple random sampling technique, 300 first-year students were enrolled from selected Senior High Schools. Structured questionnaires were used to collect data on demographic and exposure factors while rapid test kit was used to detect HBV infections. Chi-square/Fisher exact test and multivariable logistic regression were performed to determine the association between the variables at a 95% confidence interval and 0.05 significant level. Results Seroprevalence of HBV was 14% (42/300) among the students. The prevalence was significantly (p=0.001) higher in males 19.4% (34/175) than females 6.4% (8/125). 77.7% (233/300) were aware of HBV infection. Males who were circumcised were 4 times more likely to be infected with HBV (AOR=4.09, 95%CI=1.82–9.19) (p=0.001) compared with those uncircumcised. Conclusion HBV screening and education on hygienic genital circumcision practices must be prioritized in endemic countries.
