Youth obesity is a major public health problem in the United States, especially among urban-based, minority youth. The B'More Healthy Communities for Kids (BHCK) trial worked at multiple levels of the food environment, including carryouts, to increase access to and demand for healthy, affordable foods. The objective of this article is to describe the development and implementation of BHCK's carryout intervention. Process evaluation was conducted to assess intervention reach (number of interactions with youth and adults either in person or on social media), dose delivered (number of food samples and promotional materials distributed, social media posts and meetings with owners) and fidelity (availability of promoted items). Overall, the carryout intervention showed moderate to optimal reach, moderate to optimal dose delivered and moderate to optimal fidelity. These findings demonstrate a successfully implemented carryout intervention in a low-income urban setting. Lessons learned about new methods for engaging the community and increasing demand for healthy food can be used to inform future studies and programs to improve the food environment.
青少年肥胖是美国一个主要的公共卫生问题，在以城市为基础的少数族裔青少年中尤为突出。“为了孩子的巴尔的摩更健康社区”（BHCK）试验在食品环境的多个层面开展工作，包括外卖店，以增加健康、实惠食品的可及性和需求。本文的目的是描述BHCK外卖干预措施的制定与实施情况。进行了过程评估，以评估干预的覆盖范围（与青少年和成年人面对面或在社交媒体上互动的次数）、提供的剂量（分发的食品样本和宣传材料数量、社交媒体帖子以及与店主的会议次数）和保真度（促销商品的可得性）。总体而言，外卖干预措施显示出覆盖范围达到中等至最佳水平、提供的剂量达到中等至最佳水平以及保真度达到中等至最佳水平。这些发现表明在低收入城市环境中成功实施了外卖干预措施。所学到的关于吸引社区参与和增加对健康食品需求的新方法的经验教训，可用于为未来改善食品环境的研究和项目提供参考。
