The charitable food system is rapidly evolving. Interventions that target the food pantry environment and use behavioral economics are in high demand, but can be difficult to implement in a low-resource setting. This is an analysis of secondary, environment-level outcomes in a food pantry intervention (SuperShelf); the study evaluates whether the intervention resulted in measurable changes to the food pantry environment and improved diet quality of the food available to clients, compared with a control group of food pantries. Eleven food pantries were randomized to an intervention (n = 5) or control (n = 6) condition and completed baseline and one-year follow-up measures between 2018 and 2020. The intervention addressed healthy food supply and the appeal of healthy foods using behavioral economics. Assessments included manager surveys, intervention fidelity, food inventory, and food supply tracked over 5 days. Measures included change in intervention fidelity (range 0-100) with four subcomponents; Healthy Eating Index scores (HEI-2015, range 0-100) with 13 subcomponents; and Food Assortment Scoring Tool scores (FAST, range 0-100). Descriptive analyses and t-tests examined pre-post changes within and between intervention arms. Average fidelity scores increased from baseline to follow-up in the intervention group compared with the control group (p < .001), as did FAST scores (p = .02). Average HEI-2015 Total scores increased in the intervention group by 6.3 points and by 1.6 points in the control group, but the difference in change between groups was not statistically significant (p = .56). The intervention was implemented with high fidelity at five sites, with some evidence of change in the nutritional quality of the food available on the shelf to clients.
慈善食品系统正在迅速发展。针对食品储藏室环境并运用行为经济学的干预措施需求很高，但在资源匮乏的环境中实施可能具有挑战性。这是对食品储藏室干预措施（SuperShelf）的次要环境结果的分析；该研究评估了与对照组食品储藏室相比，干预措施是否导致食品储藏室环境发生了可衡量的变化，并改善了可供客户使用的食品的饮食质量。11 家食品储藏室被随机分配到干预组（n = 5）或对照组（n = 6），并在 2018 年至 2020 年间完成了基线和一年的随访测量。干预措施采用行为经济学解决了健康食品供应和健康食品吸引力问题。评估包括经理调查、干预措施保真度、食品库存以及在 5 天内跟踪的食品供应。措施包括干预措施保真度（范围 0-100）的四个子组件的变化；健康饮食指数评分（HEI-2015，范围 0-100）的 13 个子组件；以及食品分类评分工具评分（FAST，范围 0-100）。描述性分析和 t 检验检查了干预组内和组间的前后变化。与对照组相比，干预组的平均保真度评分从基线到随访期间有所增加（p <.001），FAST 评分也是如此（p =.02）。干预组的 HEI-2015 总分增加了 6.3 分，对照组增加了 1.6 分，但组间变化差异无统计学意义（p =.56）。该干预措施在五个地点得到了高度保真度的实施，并且在货架上为客户提供的食品的营养质量方面有一些变化的证据。
