Abstract
WHAT IS ALREADY KNOWN ABOUT THIS TOPIC? Approximately 80% of newly diagnosed human immunodeficiency virus (HIV) cases among individuals aged 15-24 years in China are attributed to out-of-school youth. WHAT IS ADDED BY THIS REPORT? This study presents findings on HIV prevalence and comprehensive insights into HIV service utilization, risky behaviors, and prevention knowledge among young out-of-school men who have sex with men (MSM) aged 16-24 years in China. This population exhibits a disproportionately high burden of HIV, with only 51.6% of HIV cases previously diagnosed. WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE? HIV services should be expanded to include these key populations. Tailored interventions are needed to remove barriers to regular HIV services faced by young key populations.
