ABSTRACT
INTRODUCTION:
Little is known about the epidemiology of hepatitis B virus (HBV) infection in populations from inner cities, especially in Central Brazil. Thus the objective of this study was to estimate the prevalence of HBV infection, and to analyze the factors associated with HBV infection, in a population of first-time blood donors in the southwestern region of Goiás, Central Brazil.METHODS:
A total of 984 individuals were interviewed and gave blood samples to detect serological markers of HBV (HBsAg, anti-HBs, and anti-HBc) by enzyme linked immunosorbent assays.RESULTS:
An overall prevalence of 6.9 percent was found for HBV, with constituent prevalence rates of 3.6 percent and 11.6 percent, in subjects classified as fit and unfit to donate blood according the epidemiological screening, respectively. Only three individuals were positive for anti-HBs alone, suggesting previous vaccination against HBV. The variables of prior blood transfusion (OR = 2.3), tattoo/piercing (OR = 2.1), illicit drug use (OR = 2.3), sex with a partner with hepatitis (OR = 14.7), and history of sexually transmitted diseases (OR = 2.9) were independently associated with HBV-positivity. These data suggested a low endemicity of hepatitis B in the studied population.CONCLUSION:
The findings of low hepatitis B immunization coverage and the association of hepatitis B with risky behavior highlight that there is a need to intensify hepatitis B prevention programs in the southwest region of Goiás.Palavras-chave
