Abstract
WHAT IS ALREADY KNOWN ABOUT THIS TOPIC? Self-harm represents a significant public health challenge that disproportionately affects young adults. Understanding individual- and institutional-level risk factors is crucial for developing and implementing effective mental wellness intervention programs for college students. WHAT IS ADDED BY THIS REPORT? The prevalence of youth self-harm fluctuated between 2.21% and 3.83% from 2019 to 2023. Risk factors associated with self-harm included unhealthy lifestyle behaviors, particularly internet addiction, while the implementation of regular family psychological forums was associated with reduced self-harm risk. WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE? Effective campus-based psychosocial support systems must incorporate person-centered approaches and context-specific needs, optimize resource allocation through targeted interventions, and prioritize high-risk groups exhibiting unhealthy lifestyle behaviors.
