Abstract

Background and Objectives: HEPATITIS B virus (HBV) infection is a major public health problem worldwide. Islamic Republic of IRAN is located in mesoendemic region (prevalence 2%-7%). The aim of this study was to assess PREVALENCE of chronic HBV in IRAN according to demographic characteristics.Methods: Medline, Embase, Science Citation Index Expanded, Ovid, Google Scholar, IRANMedex, SID, Magiran and The Scientific Journal of IRAN Blood Transfusion Organization (SJIBT) from 2000 till May 2008 were searched. Cross-sectional studies concerning PREVALENCE of HEPATITIS B infection in IRAN were included irrespective of language and date. The outcome of interest was PREVALENCE of chronic HBV infection detected by blood specimen positive for HBsAg.Results: We icluded 34 studies. The PREVALENCE of chronic HBV infection was estimated about 1.7% or lower in general population; 0.8% (95% CI: 0.6%-0.9%) in BLOOD DONORS and 3.2% (95% CI: 2.3% - 4.1%) in intravenous DRUG USERS. PREVALENCE of chronic HBV infection in beta thalassemic patients varied from zero to 1.5%. PREVALENCE of chronic HBV infection was higher in middle aged and elders than children, adolescent and youth and was 25% higher in males than females.Conclusions: Since mass vaccination of HEPATITIS B in 1993, PREVALENCE of chronic HBV infection has being reduced among children and adolescents. These age groups comprise a large proportion of general population and reduction of HBV infection in this age group may impact on total PREVALENCE of HEPATITIS B infection, so that now IRAN may be considered a hypoendemic region for HBV infection.
