Healthy Options At Pantries (HOAP) Study

This study will evaluate a digital nudge intervention, Healthy Options At Pantries (HOAP), in the online food pantries of three large charitable food organizations. The study will use a hybrid effectiveness-implementation design, meaning it will evaluate whether the intervention works and how it can best be rolled out in an online food pantry setting. Intervention effectiveness will be evaluated using an interrupted time series analysis to identify changes in how healthy foods ordered by shoppers are (primary outcome) by comparing food ordering data over time before and after HOAP is introduced. The study will also evaluate the possibility of collecting dietary and clinical outcomes in a small subgroup of online pantry shoppers over time comparing both in-person and at-home approaches.
