加强高质量人群研究?开创青少年自伤行为研究新局面

自伤行为是全球青少年重要的疾病负担之一，也是成年期多种健康结局的风险因素。青少年自伤行为的预防分为一般人群预防和高危人群预防，但由于相关研究存在研究设计、数据分析等方面的局限性，导致青少年自伤行为的预测和干预进展缓慢。应加强高质量的人群队列研究，结合高级统计学分析方法，进一步验证和明确青少年自伤行为的影响因素，建立准确性较高的风险预测模型，完善现有预防策略和干预措施，从而降低青少年自伤行为的疾病负担。

Strengthen high quality population-based studies to create a new research agenda for adolescents' self-injury behavior

Self-injury behavior accounts for a high proportion of disease burden among adolescents worldwide, which is also important antecedent for multiple health outcomes in adulthood. Early identification of risk factors and intervention for self-injury are of substantial importance for adolescents. Limitations in study design and data analysis of previous studies on adolescent self-injury hinder the progress in self-injury prediction and intervention. To address these limitations and improve adolescent self-injury prediction models and interventions, more evidence based on high-quality population studies with advanced statistical methods are needed.
