Interventions

  • Behavioral economics-based Healthy Options At Pantries (HOAP) digital nudge intervention — BEHAVIORAL
    Intervention will include behavioral digital nudges over a 6-month period to promote healthier food selection among online food pantry shoppers.

Study Details

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.

Arms

  • Experimental: HOAP Intervention Cohort
    Online pantry shoppers will receive the behavioral digital nudge intervention informed by the Healthy Eating Research guidelines. Nudges include: 1) traffic light labeling of foods as green (choose often), yellow (choose sometimes), or orange (choose rarely) based on levels of saturated fat, sodium, and added sugar, displayed using colored dots and borders; 2) traffic light filters for food items; 3) choice architecture to display healthier items first; 4) a nutrition summary bar to display the number and proportion of items in cart by traffic light color; and 5) opt-out healthy default nudges styled as Healthy Bonus Items. A subgroup of adult shoppers will participate in a feasibility study comparing in-person to remote collection of dietary and clinical outcomes. Subgroup participants will complete ASA24 diet recalls and provide blood pressure, weight, and body composition measurements.
