title: Hepatitis B seroprevalance and risk factors in urban areas of Malatya.
abstract: OBJECTIVE
  To determine the prevalence of hepatitis B viral markers and to assess possible risk factors in urban areas of Malatya.
  
  
  METHODS
  This was a sero-epidemiological, community based cross-sectional study and included 646 participants( female 352, male:294) from 192 houses. A face to face questionnaire was carried out and HBsAg, anti-HBc and anti- HBs markers were analyzed from blood samples using Micro ELISA technique.
  
  
  RESULTS
  The prevalence of HBsAg, anti-HBc and anti-HBs were found to be 6.0%, 29.3% and 30.3% respectively. In the final logistic regression, HBV infection (=anti HBc+) was independently associated with the age group of 21 years and older (OR=3.7, 95% CI=1.884-7.494), in illiterate subjects (OR=2.1, 95% CI=1.180-3.326), in farmers and labourers (OR=2.8, 95% CI=1.042-7.953) and in these with multiple sexual partners (OR=2.1, 95% CI=1.574-8.168). In addition, HBV infection was significantly higher in circumcised male children compare to uncircumcised ones ( chi2=5.58, P=0.01), in ones who gave birth to child at home compare to in ones who gave birth to a child at hospital ( chi2=13.86, P=0.0001).
  
  
  CONCLUSIONS
  The results of our study indicate that Malatya province has a moderate endemicity with regard to HBV infection.
