The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) is one of the largest federal food and nutrition program serving women and young children and has a low coverage rate of about 50 percent. There is no peer-reviewed article that compares maternal perceptions of challenges and barriers to WIC participation by language and participation status. We compare challenges and barriers faced by English-speaking mothers to those faced by Spanish-speaking mothers to enrollment and retention in WIC within each group: current participants (n = 43), prior participants (dropouts; n = 27), and eligible non-participants (n = 18), using focus groups we conducted in Missouri in 2021-2023.

Growing evidence suggests that resource scarcity can severely impede individuals' cognitive capacity, resulting in sub-optimal decision making. Few experimental studies investigate whether food deprivation as a form of resource scarcity influences decisions in other non-hunger related domains. We examine the effect of short term fasting on cognitive capacity by exogenously manipulating individuals' fasting time in a laboratory experiment.

Plastic, integral to food packaging since the 1950s, has become a global environmental concern due to its contribution to microplastic pollution. Microplastics harm ecosystems, impacting wildlife and human health. Amid increasing focus on sustainability, global initiatives target sustainable production and consumption, but consumers struggle to verify product claims, leading to potential greenwashing, particularly in the food industry.

This study evaluates the psychological impact of stay-at-home extension orders during COVID-19 and its relationship with individuals' expectations on the duration of the extensions. An online survey was administered to 1259 US adult residents to measure symptoms of post-traumatic stress disorder (PTSD), anxiety and stress induced by different stay-at-home order extensions using hypothetical length scenarios. We find that individuals exposed to two 2-week order extensions exhibit higher levels of stress and anxiety compared to those exposed to a single 4-week extension.

The onset of the COVID-19 pandemic disproportionately affected low-income households in the United States. As part of the government's response to the pandemic, households with children participating in the Supplemental Nutrition Assistance Program (SNAP) benefited from several temporary provisions. This study examines whether the mental/emotional well-being of children in SNAP families was influenced by the SNAP temporary provisions, overall and across subpopulations by race/ethnicity and school meal programs (SMP) participation status of children.

We implement a discrete choice experiment to examine the impact of COVID-19 exposure risk, unemployment risk, enhanced and extended unemployment benefits, and job attributes on low-skilled workers' willingness to accept (WTA) meatpacking jobs. With a sample average WTA wage of $22.77/h, the current national average meatpacking wage of approximately $15/h is too low for these workers to consider this employment opportunity.

Background: Breakfast after the bell (BAB), an alternative way to deliver breakfast after the school day begins, has been shown to increase participation in the School Breakfast Program. However, BAB occupies time that could otherwise be used for instruction and may affect academic performance. This study examined whether BAB affects math and literacy scores in third grade, an age not adequately studied in earlier literature.

Many states have adopted school-based BMI screening or surveillance programs in an effort to address high rates of childhood obesity, some of which involve provision of confidential BMI reports to parents. While there is evidence that parents are attuned to information in the reports, there is less evidence showing that the reports are effective in preventing excess childhood weight gain. Data from Arkansas, the state with the nation's first and longest running and BMI screening program, were used to measure the impact of BMI reports.

The literature identifies cultural values and beliefs as key drivers of climate change risk perception, but evidence is lacking about how media narratives and cultural values influence preferences for adapting to environmental consequences of climate change, including groundwater shortage. We elicited groundwater preferences using a choice experiment survey involving outcomes of the Mississippi River Valley Alluvial Aquifer. We randomly assigned respondents to an individualistic cultural narrative about climate change to test for framing effects predicted by culturally congruent and incongruent messaging.

The COVID-19 pandemic significantly increased food insecurity despite emergency legislation that put more resources into food assistance programs, increased unemployment benefits, and provided stimulus payments. We conducted a survey in the US on food insecurity among low-income Americans during the early months of the pandemic. While we cannot estimate causal effects, we are able to show important associations between food insecurity and nutritional and economic assistance that highlight the need to ensure that those newly at risk for food insecurity are able to connect to resources.
