Background: Injecting drug use is now recognized as a significant risk factor for HIV in sub- Saharan Africa. We evaluated prevalence and correlates of HIV among injecting drug users (IDUs) in Nigeria.
Methods: A cross sectional study using respondent driven sampling (RDS) was conducted in six Nigerian states in 2010. Current IDUs underwent interviewer-administered surveys and HIV tests. Weighted HIV prevalence and injecting risk behaviors were calculated using an RDS analytic tool. Logistic regression was used to determine correlates of HIV infection, stratified by state.
Results: Total numbers of IDUs ranged from 191 in Lagos to 273 in Kano. Median age ranged from 26 years in Cross River (CR) state to 41 years in Lagos. HIV prevalence (Fig 1) was highest in Federal Capital Territory (FCT) at 9.3%, Kaduna 5.8%, Oyo 5.1%, Kano 4.9%, CR 3.3% and Lagos 3.0%.

Although >90% of participants were male, females had higher HIV prevalence in all states surveyed except FCT (range: 7.4% in CR to 37.7% in Kano). Median duration of injecting drugs ranged from 2 years in FCT to 7 years in Lagos. Prevalence of all injecting risk behaviors was highest in FCT, ranging from 22% to 68% (table 1) for use of prefilled syringe and receptive sharing, respectively.
