Non-injection remained an independent correlate STI when adjusting for age at first sex socio-demographic characteristics (adjusted prevalence ratio (APR): 1.64, 95 % confidence interval (CI): 1.16–2.31) sexual behaviors multiple partnerships inconsistent condom use. Injection was strongly associated with (APR: 2.62, CI: 1.29–5.33); this association appeared be mediated by STI-infected partners rather than behaviors. The results underscore importance reduction all users IDUs, who face high well parenteral transmission risk.
