Children’s Healthy Weight State Capacity Building Program
Participation in multiple nutrition assistance programs early in the Covid-19 pandemic and dietary intake frequencies among WIC-participating children ages 1–4 years
Housing costs and food purchasing characteristics
Housing costs account for a significant proportion of low-income households' budgets, limiting the amount of money left for food purchases. We aimed to assess 1) the association of area- and household-level housing costs with household-level food purchasing characteristics and 2) explore the moderating effect of Supplemental Nutrition Assistance Program (SNAP) participation and SNAP purchasing power in these associations. Household-level data com…
Performance of a two-item screening for household food insecurity during WIC services
HVSS2 screening during WIC services has moderate-to-high negative (i.e., screen negative, are food secure) and positive (i.e., screen positive, are food insecure) predictive values for HFI. Dedicated staff training may be needed to improve the performance of the HVSS2 and to make HVSS2 data collected during WIC certifications more helpful in identifying and referring families experiencing HFI to more services
Overall and race-specific associations between state-level minimum wage policy and food insecurity in the United States
BACKGROUND: In the USA, states can set higher minimum wages than the federal government. We investigated the association between state minimum wages and racial/ethnic inequities in food insecurity. METHODS: Household-level food insecurity and sociodemographic data were obtained from the cross-sectional Current Population Survey 2015-2019 (n=189 665 households) and merged by state and year with minimum wage and cost-of-living data obtained from th…

Does Race/Ethnicity Explain Regional Inequities in Child Food Insufficiency During the Second Year of the Covid-19 Pandemic
Toward a more systematic understanding of water insecurity coping strategies
INTRODUCTION: Water insecurity-the inability to access and benefit from affordable, reliable and safe water for basic needs-is a considerable global health threat. With the urgent need to target interventions to the most vulnerable, accurate and meaningful measurement is a priority. Households use diverse strategies to cope with water insecurity; however, these have not been systematically characterised nor measured. The Food Insecurity Coping St…
Impact of county and state immigration policies on immigrant household enrollment in the supplemental nutrition assistance program
Many at high risk of food insecurity - including immigrants and citizens in households with immigrants - are eligible for SNAP but under-enroll. Policies that welcome and safeguard immigrants could reduce under enrollment
Detainer Requests Issued by ICE and Fair/Poor Self-Rated Health among Latines in the U.S., 2017–2020
U.S. Immigration and Customs Enforcement (ICE) issues detainer requests to local law enforcement agencies to hold detainees suspected of being undocumented immigrants until they can be transferred into ICE custody. We examined the association between area-level detainer requests and self-rated health among Latine adults. We linked health data from Latine adults included in the 2017-2020 Behavioral Risk Factor Surveillance System (n = 69,386) to d…
