consumption patterns, sexual behavior and HIV risk low-income drug users in Guatemala City EXECUTIVE SUMMARY Background HIV prevalence in Guatemala is estimated at less than 1% and is thought to be concentrated in a few key populations of at heightened risk. At present, these key populations include female sex workers (SW), with an estimated HIV prevalence of 4.3%, and men who have sex with men (MSM), with a prevalence of 12.1% (UNAIDS, 2008; Soto et al., 2007). However, in recent years the question has emerged as to whether drug users constitute a third key population in this setting. In light of the emerging recognition that not only injection, but also non-injection, drug use can heighten the risk of HIV transmission, this study was conducted to measure and analyze patterns of substance use, sexual behavior, and HIV prevalence
