•School meal participation dropped 46% during COVID-19 school closures in California.•Districts had valuable but partial meal access information during school closures.•Number of school meal sites ...dropped 32% during COVID-19 school closures.•School meal sites tended to be placed in priority population areas.•Density of school meal sites was disproportional to density of populations in need.
The National School Lunch and School Breakfast programs are a nutrition safety net for millions of children in the United States, particularly children in households with lower incomes. During Spring 2020 COVID-19 school closures, schools served school meals through the Summer Meal Programs. Despite efforts to increase access, meal participation declined and food insecurity increased. We aimed to (1) describe meal program features as communicated in low-income California school districts’ on-line resources (2) examine associations between meal program features and change in meal participation between May 2019 and May 2020 and (3) evaluate equity by describing meal site coverage and placement relative to the size of priority populations. Data from district online resources and meal reimbursement claims were collected for a stratified, random sample of 190 CalFresh Healthy Living-eligible districts. Linear regression was used to examine associations between district meal program features and percent change in meal participation. Meal site location and density were examined in relation to the size of priority populations. In May 2020, compared to May 2019, total meals served decreased by a median 46%. There were gaps in the information provided in district online resources and low variation in measured district meal program features. These features explained little of the variation in the percent change in meal participation. A greater proportion of meal sites were placed in areas with larger priority populations, yet the density of sites was not proportionate to the priority populations’ sizes. Findings show actionable areas for improving meal access during school closures.
Describe, and assess disparities in, the changes in Supplemental Nutrition Assistance Program Education (SNAP-Ed) that occurred the year before vs. the year when COVID-19 restrictions were ...implemented.
Observational study comparing reach, intensity, and dose of California Local Health Department (LHD) SNAP-Ed interventions in Federal Fiscal years 2019 and 2020 (FFY19, FFY20).
Student t-tests determined significance of differences in the number of Direct Education (DE) programs, Policy, Systems and Environmental change (PSE) sites, people reached, and intervention intensity and dose between FFY19 and FFY20 using data reported online by LHDs. Linear regression assessed associations between census tract-level characteristics (urbanicity; percentages of population with income <185% of federal poverty level, under 18 years of age, and belonging to various racial/ethnic groups; and California Healthy Places Index) and changes in number of DE programs, PSE sites, people reached, and intervention dose between FFY19 and FFY20.
From FFY19 to FFY20, the number of DE programs, PSE sites, people reached, and census tract-level intervention intensity and dose decreased. Higher census tract poverty, higher proportions of Black and Latino residents, and less healthy neighborhood conditions were associated with greater decreases in some intervention characteristics including PSE sites, PSE reach, DE programs, and DE dose.
These reductions in LHD SNAP-Ed interventions indicate reduced access to education and environments that support healthy eating and obesity prevention during a time when this support was especially needed to reduce risk of COVID-19 infection and complications. Disproportionately reduced access, may have worsened health disparities in already-disadvantaged communities. Assuring maintenance of SNAP-Ed interventions, especially in disadvantaged communities, should be a priority during public health emergencies.

California’s Department of Public Health (CDPH) distributes Supplemental Nutrition Assistance Program-Education (SNAP-Ed) funding, known as CalFresh Healthy Living (CFHL) in California, to local ...health departments to implement school-based physical activity/nutrition interventions. We determined the association between intervention presence/dose and student cardiorespiratory fitness and BMI.
This cross-sectional, observational study included 5th and 7th grade students with 2016–17 FitnessGram® results who attended SNAP-Ed eligible California schools. Intervention group students attended schools with CDPH-CFHL interventions during October 2015-September 2016 (n = 904 schools; 97,504 students, 49% female); comparison group students attended schools without CDPH-CFHL interventions (n = 3,506 schools; 372,298 students, 49% female). Adjusted multilevel models determined the association between school-level intervention presence/dose and students’ cardiorespiratory fitness (estimated VO2max) and BMI z-score, and tested for effect modification by student grade and sex.
Students attending intervention schools demonstrated greater VO2max (males: 0.18 mL/kg per min, 95% CI: 0.03, 0.34; females = 0.26 mL/kg per min, 95% CI: 0.13, 0.39) and lower BMI z-scores (males: −0.03, 95% CI: −0.05, −0.02; females = -0.02, 95% CI: −0.04, −0.01) than students in comparison schools. Students in schools with the highest intervention levels demonstrated higher VO2max (0.37 (95% CI: 0.06, 0.16) and 0.22 (95% CI: 0.02, 0.42), respectively), than comparison students, with the strongest associations seen for females and 7th graders.
On average, students in schools with CDPH-CFHL physical activity interventions demonstrated better cardiorespiratory fitness and slightly lower BMI z-scores than students in comparable schools without such programing. Investment in these interventions may positively impact students’ cardiorespiratory health, though further causal investigation is warranted.
Schools are a critical setting for improving child nutrition and food security and preventing obesity in the United States. The U.S. Department of Agriculture mandates that the Supplemental Nutrition ...Assistance Program–Education, known as CalFresh Healthy Living (CFHL) in California, implements obesity prevention efforts that utilize multicomponent policy, systems, and environmental change interventions supplemented with direct and indirect education. However, evaluation of these complex interventions has proven challenging due to a lack of established evaluation methods, particularly for comprehensively measuring the dose of multicomponent interventions. This article proposes and demonstrates a method to score the dose of multicomponent California Department of Public Health–funded CFHL school interventions received by children attending public schools, using administrative data collected by CFHL in California.
Although genome-wide hypomethylation is a hallmark of many cancers, roles for active DNA demethylation during tumorigenesis are unknown. Here, loss of the APC tumor suppressor gene causes ...upregulation of a DNA demethylase system and the concomitant hypomethylation of key intestinal cell fating genes. Notably, this hypomethylation maintained zebrafish intestinal cells in an undifferentiated state that was released upon knockdown of demethylase components. Mechanistically, the demethylase genes are directly activated by Pou5f1 and Cebpβ and are indirectly repressed by retinoic acid, which antagonizes Pou5f1 and Cebpβ.
Apc mutants lack retinoic acid as a result of the transcriptional repression of retinol dehydrogenase l1 via a complex that includes Lef1, Groucho2, Ctbp1, Lsd1, and Corest. Our findings imply a model wherein APC controls intestinal cell fating through a switch in DNA methylation dynamics. Wild-type APC and retinoic acid downregulate demethylase components, thereby promoting DNA methylation of key genes and helping progenitors commit to differentiation.

► Loss of tumor suppressor Apc increases DNA demethylase activity via retinoic acid (RA) ► The demethylase keeps intestinal cells undifferentiated in Apc mutants ► Mutations in Apc suppress RA production via CtBP, LSD1, Groucho2, CoRest, and Lef1 ► The decrease in RA derepresses Pou5f1 and Cebpβ, which directly target the demethylase
