  • The Community Eligibility Provision (CEP) allows schools in low-income areas to provide free meals to all students, but its effects on obesity are unclear.
  • The study analyzed BMI data from California public schools to assess the link between CEP participation and child obesity rates using a difference-in-differences method.
  • Results showed that schools participating in CEP had a 0.60-percentage-point decrease in obesity rates, indicating potential benefits of universal free school meals for children's health.

Policymakers aim sugar-sweetened beverage (SSB) taxes at decreasing SSB consumption; however, little is known about their impact on beverage marketing in the retail environment. We assessed changes in interior marketing displays within large food stores before and after the implementation of Seattle's SSB tax. We used Poisson difference-in-difference (DID) models to estimate whether presence and variety of interior beverage marketing displays in Seattle changed from before to after the tax compared to displays in non-taxed comparison area stores, overall, and by beverage type.

Article Synopsis
  • School meals are essential for children's nutrition and health in the U.S., but COVID-19 school closures hindered access, prompting the implementation of P-EBT and grab-and-go meals for low-income families.
  • The objective of a study conducted from March to June 2020 was to evaluate how many eligible youths received these benefits, how much they received, and the cost of running the programs.
  • Results showed that while grab-and-go meals reached about 27% of eligible youths (8 million), P-EBT was more effective, reaching 89% (26.9 million), distributing significant cash benefits and meals.

Taxing sweetened beverages has emerged as an important and effective policy for addressing their overconsumption. However, taxes may place a greater economic burden on people with lower incomes. We assess the degree to which sweetened beverage taxes in three large US cities placed an inequitable burden on populations with lower incomes by assessing spending on beverage taxes by income after taxes have been implemented, as well as any net transfer of funds towards lower income populations once allocation of tax revenue is considered.

Policy makers in several major cities have used quantitative data about local food environments to identify neighborhoods with inadequate access to healthy food. We conducted qualitative interviews with residents of a healthy food priority area to assess whether residents' perceptions of food access were consistent with previous quantitative findings, and to better understand lived experience of food access. We found that proximity to stores, transportation mode, and cost shaped decisions about food shopping.

To test whether fruit drink countermarketing messages alone or combined with water promotion messages reduce Latinx parents' purchases of fruit drinks for children aged 0 to 5 years. We performed a 3-arm randomized controlled online trial enrolling 1628 Latinx parents in the United States during October and November 2019. We assessed the effect of culturally tailored fruit drink countermarketing messages (fruit drink‒only group), countermarketing and water promotion messages combined (combination group), or car-seat safety messages (control) delivered via Facebook groups for 6 weeks on parental beverage choices from a simulated online store.

Social desirability bias has been documented in self-reported diet as well as in voting behavior, but not in regards to sweetened beverage consumption or sweetened beverage taxes. We find evidence that respondents in a mixed-mode opinion survey exhibit social desirability bias in both reported sweetened beverage consumption and beliefs about the health and economic benefits of sweetened beverage taxes. We do so in a study of 1704 adults residing in Seattle, Minneapolis, and the D.

Background: Federal law requires water access in schools where meals are served. Schools report high rates of water accessibility in cafeterias, but observations indicate lower adherence. Although observation is costly, it permits a more detailed assessment of a water source to determine whether it provides effective access that encourages water consumption and thus, healthy hydration for students.

An increase in health-related community resources related to tribal ownership of casinos may be one mechanism through which the health of Native Americans is improved. However, no studies have quantitatively assessed whether casinos are associated with having more community resources.

Introduction: Although the regionalization of public health systems has been well documented in the case of emergency preparedness, there is little literature on the application of regional approaches to other aspects of public health. From 2011 through 2014 the Washington State Department of Health implemented a Community Transformation Grant to support community-level policy and systems changes to decrease chronic disease risk factors and increase access to clinical preventive services. The Department of Health implemented the grant through a regional model, grouping 32 of the state's 35 local health jurisdictions into 5 regions.
