This paper presents details the Healthy Foods Hawai'i (HFH) intervention trial, aimed to improve children's dietary behavior to prevent child obesity, by modifying the food environment with community-selected foods. Four communities were selected by ethnic composition, income level, two on O'ahu and one neighbor island. On each island one community was randomly assigned to intervention and one to control. The intervention was implemented through food stores in the intervention communities. HFH was designed to strengthen the network between local food producers, food distributors, storeowners and consumers, to increase the availability of healthier less energy dense foods for children in underserved rural communities of Hawai'i. The intervention includes phases: healthier beverages, snacks, condiments, and family meals. Moderate to high fidelity was achieved for educational materials (shelf labels, posters and educational displays). The number of educational displays varied by intervention phase and community. Posters were found in place 100% of the time. Shelf labels were found intact in the correct location. Low to moderate fidelity was achieved for distributors, with some products not stocked. In the intervention communities, 6-8 week phases focused on target foods with 40 food demonstrations. A total of 1582 food related samples were distributed. A high to moderate dose and reach of the overall intervention was achieved in delivery of the cooking demonstrations. A high to moderate dose and reach of the intervention was achieved overall; fidelity to the intervention protocol was moderate. To improve healthy local food availability in stores in rural communities in Hawai'i, agricultural producers reported needing additional support to sell and transport product to local stores, rather than to centralized distributors.
本文详细介绍了“夏威夷健康食品”（HFH）干预试验，该试验旨在通过采用社区选定的食品来改变食物环境，从而改善儿童的饮食行为以预防儿童肥胖。根据种族构成和收入水平选取了四个社区，其中两个在瓦胡岛，一个在邻岛。在每个岛屿上，一个社区被随机分配到干预组，另一个被分配到对照组。干预措施通过干预社区的食品商店来实施。HFH旨在加强当地食品生产商、食品经销商、店主和消费者之间的网络，以增加夏威夷农村贫困社区儿童可获得的更健康、能量密度更低的食品。干预措施包括几个阶段：更健康的饮料、零食、调味品和家庭膳食。教育材料（货架标签、海报和教育展示）实现了中到高保真度。教育展示的数量因干预阶段和社区而异。海报在所有时间都能看到。货架标签在正确位置完好无损。经销商实现了低到中等保真度，有些产品没有进货。在干预社区，6至8周的阶段专注于目标食品，并进行了40次食品示范。总共分发了1582份与食品相关的样品。烹饪示范的总体干预实现了高到中等剂量和覆盖范围。总体而言，干预实现了高到中等剂量和覆盖范围；对干预方案的保真度为中等。为了提高夏威夷农村社区商店中本地健康食品的可获得性，农业生产商报告称，他们需要额外的支持，以便将产品销售并运输到当地商店，而不是集中的经销商。
