The purpose of this scoping review is to identify what community engagement (CE) research approaches have been applied by researchers in the retail food environment (RFE) intervention literature and how they vary by type of retail settings, phase of intervention, year of intervention, and key domains of equity. A total of 98 RFE interventions reported in 104 reports were included in this review, and most were implemented in either supermarkets (21%), corner stores (20%), or multiple RFE settings (21%). All interventions employed CE research strategies of outreach (n = 98), whereas approximately half employed strategies of shared leadership (n = 52). Exploring CE research strategies by RFE settings and intervention phase, this review found stronger forms of CE in less traditional RFE settings, including mobile markets, and among interventions that used CE research strategies across all phases of the intervention study. RFE interventions that implemented the highest forms of CE research strategies (ie, shared leadership) were also those that addressed all key equity domains. The findings of this review reveal that the form of CE in RFE interventions varied widely, with more domains of equity addressed when higher forms of CE were used. Insights from this review suggest that future research should prioritize assessing the effectiveness of shared leadership CE strategies on achieving and sustaining nutrition-related health equity outcomes for communities.
