This study examines how removing synthetic dyes from the food supply impacts the nutritional quality of grocery purchases among families with children, focusing on the 7 dyes targeted by FDA for phase-out by the end of 2026 (some of which are required (i.e., red dye #3), while the removal of others are voluntary). Aim 1 More

The Robert Wood Johnson Foundation’s (RWJF) commitment to child obesity ends in December 2025, marking the conclusion of a two-decade investment in Healthy Eating Research (HER). As part of our RWJF legacy, HER is developing a national research agenda for policy, systems, and environmental (PSE) interventions and strategies to promote food and nutrition security, optimal More

The purpose of this study was to evaluate the effects of the state Earned Income Tax Credit on food insecurity among economically at-risk U.S. households with children and explore differential effects across sociodemographic groups. The authors used an intent-to-treat causal inference design and household-level data from all 50 U.S. states available from the Current Population More

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 More

This study aimed to assess whether state minimum wage generosity was associated with change in food insecurity among households with children and explore differential policy impacts across sociodemographic groups. This cross-sectional study of a national sample of US households from the Current Population Survey used a 2-way fixed effects modeling approach to test whether increases More

Researchers increasingly conduct online surveys or experiments. Unfortunately, online approaches can attract fraudulent respondents from individuals who are ineligible, but respond to distort results or obtain study incentives. This can be difficult to detect. This paper aims to share lessons learned from a recent online study to support other researchers.

As researchers increasingly utilize systems science simulation modeling (SSSM), little is known about how and by whom SSSMs are being leveraged to address inequities in access to healthy diets. We evaluated the extent to which studies (n = 66) employing SSSM to examine retail food environments (RFEs): included three pillars of equity (social position, human capital, socioeconomic More

Food and beverage marketing drives poor diet quality and obesity risk among children. However, it is unknown how much young children are exposed to digital food and beverage marketing on mobile devices like tablets and smartphones. The objective of this study was to estimate how frequently young children, who are particularly vulnerable to advertising, view More

This study aimed to understand experiences with COVID-19 economic relief measures among low-wage worker households with children during the COVID-19 pandemic. The study conducted semi-structured qualitative interviews from low-wage workers in households with children in two U.S. cities in 2022 (n = 40). The sample was recruited from a larger study which included survey measures More

Urban grocery stores are facing operational challenges due to crime and are instituting crime mitigation strategies. These strategies may have unintended consequences that limit healthy food access among families with children and create threats to social dignity. This community-driven study aims to: 1) quantify modifiable community characteristics associated with crime at grocery stores; 2) examine More
