Men who have sex with men (MSM) has emerged as a key population in the global HIV epidemic. Modeling work on the Asian epidemic points to a scenario in which 42 percent of all new HIV infections in Asia will occur among MSM by 2020. While population-based surveys in countries with generalized epidemics have generated vast amounts of data on sexual behavior, studies on MSM and other hidden populations struggle to generate representative samples and adequate sample sizes. The lack of representative data of MSM risk-behavior severely hinders an understanding of the underlying dynamics of the MSM epidemics and prevents an evidencebased response. New cost-efficient methods for representative sampling of MSM and other hidden groups are thus needed.
