HIV and syphilis infections among drug users in China - what we can learn from HIV/AIDS comprehensive surveillance.

[Abstract] Objective To determine the prevalence of HIV唱1,syphilis,relative factors associated with HIV唱1 and syphilis infection among drug users in China.Methods Chinese HIV/AIDS comprehensive surveillance is a routine work; the data on drug users in 2005 were analysed; HIV唱1 and syphilis antibody status was obtained from blood tests; demographic and behavioural data were collected through standardized interviews.Logistic regression was used to analyse independent association between HIV唱1 and syphilis status and risk behaviours.Results HIV唱1 antibody prevalence was 5畅0%,with large regional differences.Syphilis positive rate was 2畅8%.Logistic re唱 gression analysis showed demographic and behavioural factors significantly associated with HIV prevalence were: minority versus Han唱Chinese(OR 4畅10; P 9 years(OR 1畅61;P =0畅001), IDU with needle唱sharing versus non唱IDU(OR 4畅44; P 9 years (OR 2畅27; P <0畅001). Conclusion HIV唱1 prevalence among drug users in China is relatively high(5%)and the risk of HIV唱1 infection is associated predominantly with minority status,low education and injecting drug use.Special interventions among drug users in China are strongly warranted.
