The Healthy Young Men's Study: Sampling Methods to Recruit a Random Cohort of Young Men Who Have Sex With Men

Abstract
Recruiting a scientifically sound cohort of young men who have sex with men (YMSM) is an enduring research challenge. The few cohort studies that have been conducted to date on YMSM have relied on non-probability sampling methods to construct their cohorts. While these studies have provided valuable information about HIV risk behaviors among YMSM, their generalizability to broader YMSM populations is limited.
