Women are at a significantly greater risk for Hepatitis C (HCV) infection via drug injection than men, according to a new study that draws questions to the role of hormones in infectious disease contraction.
Researchers found in data of 1,868 people that women who inject drugs are at a 38% greater risk of contracting HCV than men who inject drugs. Although HCV can be commonly contracted through the sharing of syringes and other injections equipment, noted differences in these behaviors did contribute to the greater rate of women contraction found in the study.
An adjusted female-to-male hazard ratio (HR) for HCV infection was found with a Cox proportional hazard model. Calculated behavioral and demographic risk factors used to adjust the HR had little change on the disparity, researchers noted.
