Adolescence is a pivotal point in the life course, characterised by transformative physical, cognitive, and emotional growth, an openness to change, and a drive to reshape the social environment. It offers unique opportunities to adopt changes in diet and physical activity that can persist into later life. Yet pre-existing nutritional problems, including micronutrient deficiencies, food insecurity, and poor-quality diets, persist at the same time as adolescents face the rapid emergence of an obesity epidemic. Adolescent growth and nutrition has been largely overlooked in intervention and policy research. Most intervention studies have emphasised micronutrient supplementation, with few taking into account the multiple drivers of adolescent diets. This Series paper highlights that effective interventions and policies will need to cut across sectors; be supported by multifaceted and multilevel policy; and extend across education, health, food systems, social protection, and digital media. Better data standardisation and systems will be essential in coordinating and monitoring these responses. In a context of shifts in planetary ecosystems and commercial drivers, resilient food systems will need to both ensure access to healthy and affordable foods and provide the infrastructure and incentives for continuing physical activity. Intergenerational partnerships with young people will be essential in bringing about transformative change and ensuring that food policies reflect their needs and aspirations.
青春期是人生历程中的一个关键点，其特征是身体、认知和情感的转型式成长、对变化的开放性以及重塑社会环境的动力。它提供了独特的机会来改变饮食和身体活动习惯，这些改变可以持续到成年以后。然而，在青少年面临肥胖流行迅速出现的同时，先前存在的营养问题，包括微量营养素缺乏、粮食不安全和不良饮食质量，依然存在。青少年的成长和营养在干预和政策研究中很大程度上被忽视了。大多数干预研究都强调补充微量营养素，很少考虑到青少年饮食的多种驱动因素。本系列文章强调，有效的干预措施和政策需要跨部门实施；得到多方面、多层次政策的支持；并涵盖教育、卫生、食品系统、社会保护和数字媒体等领域。更好的数据标准化和系统对于协调和监测这些应对措施至关重要。在地球生态系统和商业驱动因素发生变化的背景下，有韧性的食品系统既要确保获得健康和负担得起的食物，又要为持续的身体活动提供基础设施和激励措施。与年轻人建立代际伙伴关系对于实现变革性变化以及确保食品政策反映他们的需求和愿望至关重要。
