Risky Sexual Behavior, Bleeding Caused by Intimate Partner Violence, and Hepatitis C Virus Infection in Patients of a Sexually Transmitted Disease Clinic

摘要

Objectives. We sought to investigate independent contributions of risky sexual behaviors and bleeding caused by intimate partner violence to prediction of HCV infection.Methods. We conducted a case-control study of riskfactors among patients of a sexually transmitted disease clinic with and without HCV antibodies, group-matched by age.Results. Multivariate analyses indicated that Black race (odds ratio [OR] = 2.4; 95% confidence interval [Cl] = 1.3,4.4), injection drug use (OR = 20.3; 95% Cl = 10.8, 37.8), sharing straws to snort drugs (OR = 1.8; 95% CI = 1.01, 3.0), sharing razors (OR=7.8; 95% Cl = 2.0,31.0), and exposure to bleeding caused by intimate partner violence (OR = 5.5; 95% Cl = 1.4, 22.8) contributed significantly to the prediction of HCV infection; risky sexual behavior and exposure to blood or sores during sexual intercourse did not.Conclusions. HCV risk among patients of a sexually transmitted disease clinic can be explained by direct blood exposure, primarily through injection drug use. Exposure to bleeding caused by intimate partner violence may be a previously unrecognized mechanism for HCV transmission associated with risky sexual behavior.
