title: Risk factors for hepatitis C infection among sexually transmitted disease-infected, inner city obstetric patients.
abstract: OBJECTIVE
  To test the hypothesis that our inner city obstetric patients who have been infected with sexually transmitted diseases (STDs) will have a higher prevalence of hepatitis C virus infection than the general population and to identify specific risk factors and high-risk groups.
  
  
  METHODS
  All patients in our prenatal clinic (July 1997-April 1999) who tested positive for one or more STDs were asked to return for hepatitis C antibody testing. Medical charts of all patients who returned for hepatitis C testing were reviewed.
  
  
  RESULTS
  A total of 106 patients with STDs were tested for hepatitis C. Positive screening tests for anti-hepatitis C antibody were found in 6.6% (7/106) of the patients (95% CI = 2.7-13.1%). This frequency is significantly higher than the hepatitis C prevalence (1.8%) in the general United States population (p = 0.006). Multiple logistic regression analysis confirmed only older age (p = 0.0 16) and positive HIV status (p = 0.023) to be significant predictors of hepatitis C infection.
  
  
  CONCLUSIONS
  Inner city STD-infected obstetric patients are at high risk for hepatitis C infection compared with the general population. Increasing age and HIV-positive status are risk factors which are significantly associated with hepatitis C infection.
