目的：我们建立了一个应用程序，以帮助客户的食品储藏室。该应用程序提供基于蔬菜的食谱，食品提示和无成本策略，使用餐时间更健康，并为讨价还价意识杂货店购物，以及其他主题。用户自定义材料，以满足自己的喜好。该应用程序，可在英语和西班牙语，已在随机现场试验进行了测试。设计：一个随机对照试验，在10周内重复测量。设置：在洛杉矶县，美国的15个社区食品储藏室分布的客户。参与者：分布被随机控制和实验条件下，289个家庭厨师和他们的9-14岁的孩子之一被招募为参与者。实验二人组获得了一个智能手机与我们的应用程序和手机使用计划，然后训练使用该应用程序。“测试蔬菜”被添加到控制和实验参与者在他们的p茶水间收到的食物中。结果：经过3-4周的额外“测试蔬菜”，实验茶水间的厨师比控制厨师多准备了38%的这些物品（P=0.03）。基线后10周，实验茶水间在使用更广泛的蔬菜种类方面也比对照茶水间获得了水收益（P=0.003）。应用程序的使用增加之间的中期实验和最终测量（P= 0.0001）。结论：该应用程序似乎鼓励家庭厨师尝试新的制备方法，并扩大他们的蔬菜纳入家庭饮食。需要进一步研究，以确定对结果贡献最大的具体应用程序功能，并测试广泛传播应用程序的方法。
Objective: We built an app to help clients of food pantries. The app offers vegetable-based recipes, food tips and no-cost strategies for making mealtimes healthier and for bargain-conscious grocery shopping, among other themes. Users customize materials to meet their own preferences. The app, available in English and Spanish, has been tested in a randomized field trial.Design: A randomized controlled trial with repeated measures across 10 weeks.Setting: Clients of fifteen community food pantry distributions in Los Angeles County, USA.Participants: Distributions were randomized to control and experimental conditions, and 289 household cooks and one of their 9-14-year-old children were enrolled as participants. Experimental dyads were given a smartphone with our app and a phone use-plan, then trained to use the app. 'Test vegetables' were added to the foods that both control and experimental participants received at their pantries.Results: After 3-4 weeks of additional 'test vegetables', cooks at experimental pantries had made 38% more preparations with these items than control cooks (P=0.03). Ten weeks following baseline, experimental pantries also scored water gains in using a wider assortment of vegetables than control pantries (P=0.003). Use of the app increased between mid-experiment and final measurement (P= 0.0001).Conclusions: The app appears to encourage household cooks to try new preparation methods and widen their incorporation of vegetables into family diets. Further research is needed to identify specific app features that contributed most to outcomes and to test ways in which to disseminate the app widely.
