Resumo
In order to investigate the seroepidemiology of the hepatitis B virus (HBV) infection in
illicit drug users (DU) in Campo Grande City, Mato Grosso do Sul, 268 individuals
were interviewed regarding socio-demographic data and HBV risk factors. After,
blood samples were collected and serum samples were tested to HBV markers
(HBsAg, anti-HBs e anti-HBc) by enzyme-linked immunosorbent assay (ELISA). The
mean age of the drug users was 27.8 years. The majority of them was male (88%),
single (60.5), white (75%), and birth in Mato Grosso do Sul (66.8%). Also, 66.3% had
low income and schooling (60%). Of the total individuals investigated, 10.1% (95%
IC: 6.9 14.5) were positive for the HBV markers, ranging from 9.4% in non injection
drug users to 14.7% in injection drug ones. One individual was HBsAg positive; two
anti-HBc positive only, and 24 anti-HBc and anti-HBs positive. In 26 individuals only
the anti-HBs was detected, suggesting previous hepatitis B vaccination. Further, age
of 30 years or more and use of condom irregularly during intercourse were factors
independently associated with HBV infection (p<0.05). The findings of this
investigation highlight the need of public health programs, mainly regarding the
prevention of sexual transmission of HBV and hepatitis B vaccination
