Adolescence is a high-risk period for obesity, and it is crucial and urgent to implement obesity control among adolescents. However, existing interventions commonly face challenges in sustainability and scalability. Asset assessment to identify and leverage existing community assets and strengths is essential to facilitate and maintain the implementation of these programs.

To assess assets for obesity control among middle school students, and to identify the advantages and deficiencies in the current policy, physical, social, and information environments, along with suggestions for improvements.

From 2023 to January 2024, purposive sampling method was adopted, face-to-face one-by-one interviews were conducted with 11 staff members involved in obesity control for middle school students from the Center for Disease Control and Prevention, Education Bureau, and three middle schools in a major city in East China. Additionally, eight parents and their children from each of the three schools were invited to participate in focus group discussions, with 6 groups and 8 participants per group. Thematic analysis was applied to analyze the interview data.

This study found that the advantages in obesity control for middle school students primarily included policies and conditions ensured for obesity surveillance, nutritional school lunch and physical activity, along with media for health communication. The main deficiencies were the lack of specific policies for efficient obesity control, insufficient physical and social assets to support healthy eating and physical activity, and the quality and intensity of information assets supporting to facilitate changes in knowledge, attitude, and behaviors. In response to these challenges, participants suggested the implementation of both rigid regulations and flexible incentives, improvement of asset accessibility, encouragement of multi-stakeholder cooperation, and strengthening of health communication. Integrating existing assets and suggestions for improvement has formed an asset assessment checklist, corresponding to 10 assets from the policy environment, 8 from the physical environment, 20 from the social environment, and 12 from the information environment.

Several assets exist for obesity control among middle school students and identifies areas for improvement. Subsequent efforts in obesity control for middle school students should be made on promoting intervention strategies to better align with the context based on the asset assessment checklist to diagnose the current status of assets, thus enhancing the efficacy and sustainability of the program.

青春期是肥胖问题的高风险期，针对青少年开展肥胖防控尤为紧迫和必要。然而现有干预措施普遍面临无法持续开展或扩大推广的困境，亟需通过资源评估识别和发掘现有的社区资源或优势，促进青春期肥胖防控项目的开展和维持。

对初中生肥胖防控进行资源评估，识别获得当下政策环境、物质环境、社会环境、信息环境中的优势资源、不足之处与改进建议。

2023—2024年1月采用目的抽样法，从中国东部某市疾病控制中心、教育局、城区3所初级中学中选取11名承担初中生肥胖防控相关工作的工作人员进行一对一、面对面访谈；在以上3所初中各邀请8名家长及其子女进行专题小组访谈，每组8人，共计6组。通过主题分析法对访谈资料进行分析。

关于初中生肥胖防控，受访者提及的优势资源主要包括实现肥胖监测、保障校内营养膳食和体育运动的政策与条件，以及可用于传播健康信息的宣传媒介；不足之处主要为缺乏可高效推进肥胖防控的专项政策与方案、各场所的物质和社会环境资源无法充分支持健康饮食与运动、信息环境资源的质量与力度难以促成知信行转变等。关于改善资源环境，受访者提出的建议主要包括落实刚性监管和柔性激励、提高资源可及性、动员多方合作和强化健康宣教等。整合现有资源和改进建议形成了一份资源评估清单，分别对应10类政策环境资源，8类物质环境资源，20类社会环境资源和12类信息环境资源。

当前各环境中存在多项有利于初中生肥胖防控的优势资源，但也面临诸多不足之处亟需改善。后续初中生肥胖防控可参考资源评估清单诊断资源现状，使干预措施更好地匹配现有环境，以增强干预策略的效果与可持续性。
