Objective: to analyze the factors associated with hepatitis B infection among primary healthcare service users in Selo Mateus-BS. Methods: This was a case-control study with 74 cases and 74 controls matched by gender, age and place of service provision. Conditional logistic regression was used for multivariate analysis (odds ratio - OR - and respective 95% confidence intervals - 95%C!). Results: the bivariate analysis identified race/color (p<0.145); having a sexually transmitted disease in the last 5 years (p<0,197); schooling (p<0.006) and place of residence (p<0.014) as being appropriate for the multivariate analysis model (p<0.200). The multivariate analysis identified the factors associated hepatitis B infection as being: living in a rural area (OR=6.37; 95%0:1.61-25.14; p=0.008) and schooling (OR=20.02; 95%02.36-173.06, p=0.006). Conclusion: vaccination and condom use in all sexual activities should be encouraged. especially among populations with no schooling and those living in rural areas.
