This article examines infection with viral hepatitis A, B, and C and socioethnic factors in a population of injection drug users seeking treatment. The study was conducted between 2001 and 2003 in a rural German hospital; selected sociodemographic and drug-related data as well as a serology for hepatitis A, B, and C were obtained from 1499 patients. Statistical analyses were performed by univariate analysis of variance and post hoc Scheffé tests or with the chi(2) test and Bonferroni adjustment. Ethnic minority patients manifested a more severe course of addiction and showed a higher frequency of infection with hepatitis A, B, and C. Low-threshold culture-sensitive drug user treatment programs should be implemented and evaluated. The study's limitations are noted.
