The intersection between eating behaviours and mental health has garnered substantial attention in recent years. For this Review, we systematically reviewed the available research to find out the prevalence of food addiction as measured by the Yale Food Addiction Scale, and to investigate its association with mental health-related outcomes in adolescents. Eight databases were searched using keywords from Jan 1, 2009, to Aug 5, 2020, to identify studies reporting a Yale Food Addiction Scale diagnosis or symptom score, or both. In total, 27 studies were included. The prevalence of a food addiction diagnosis ranged from 2·6% to 49·9% in non-clinical and clinical populations, and prevalence was higher in women and adolescents with a higher weight status. Food addiction was associated with disordered eating, depressive and anxiety symptoms, and a poorer quality of life and self-esteem. These associations have important implications for the assessment and management of eating behaviours and mental health in adolescents. Transdiagnostic prevention and management intervention strategies could be explored.

近年来，饮食行为与心理健康之间的交叉点引起了广泛关注。在这篇综述中，我们系统地回顾了现有的研究，以找出耶鲁大学食物成瘾量表所衡量的食物成瘾的流行程度，并调查其与青少年心理健康相关结果的关联。使用关键字从 2009 年 1 月 1 日到 2020 年 8 月 5 日搜索了八个数据库，以确定报告耶鲁食物成瘾量表诊断或症状评分或两者的研究。共纳入 27 项研究。在非临床和临床人群中，食物成瘾诊断的患病率从 2·6% 到 49·9% 不等，并且在体重状况较高的女性和青少年中患病率更高。食物成瘾与饮食紊乱、抑郁和焦虑症状有关，以及较差的生活质量和自尊。这些关联对于评估和管理青少年饮食行为和心理健康具有重要意义。可以探索跨诊断预防和管理干预策略。
