Universal School Meals During the Pandemic: A Mixed Methods Analysis of Parent Perceptions from California and Maine.

BACKGROUND: In response to the COVID-19 pandemic, the United States Congress authorized the United States Department of Agriculture to waive a variety of school meal regulations and funded school meals daily for all students at no charge regardless of family income. Since federal Universal Free School Meals (UFSM) ended with the 2021-2022 school year, several states, including California and Maine, adopted state-level UFSM policies. OBJECTIVE: This study aimed to understand parent perceptions of school meals and the federal and new state UFSM policies in California and Maine, including potential challenges and benefits to students and households. DESIGN: A mixed methods study design was used. A quantitative cross-sectional survey was administered, and semi-structured interviews were conducted in English and Spanish during the 2021-2022 school year. PARTICIPANTS/SETTING: The quantitative survey was administered to parents of students in elementary, middle, and high schools in rural, suburban, and urban communities in California (n=1,110) and Maine (n=80). Qualitative interviews were then conducted with a subset of these parents in California (n=46) and Maine (n=20) using ZoomTM. Most survey participants (708 out of 1,190; 59.5%) and interviewees (40 out of 66; 60.6%) were parents of students who were eligible for free or reduced-price meals (FRPM). MAIN OUTCOME MEASURES: Parents' perceptions of UFSM, school meal quality, and experiences applying for FRPM were examined. ANALYSES PERFORMED: Tests of proportions were used to analyze survey data. Using grounded theory, interview transcripts were analyzed qualitatively by 2 trained research assistants, applying principles of content analysis to identify themes and domains. Inter-rater reliability was conducted. RESULTS: Parents perceived that school meals and UFSM saved families money and time, as parents had fewer meals to purchase and prepare for their children. Additionally, UFSM reduced parents' stress and reduced stigma for children and for parents, who described feelings of embarrassment when they previously filled out paperwork for FRPM. While parent perceptions of school meal quality and healthfulness were mixed, most parents reported feeling grateful for school meals. CONCLUSIONS: Parents had mixed opinions on the quality and healthfulness of school meals, but believed UFSM saved them money and time and reduced their stress. Parents also felt UFSM reduced stigma for families.

Competitive Foods' Nutritional Quality and Compliance with Smart Snacks Standards: An Analysis of a National Sample of U.S. Middle and High Schools.

Snacks and beverages are often sold in addition to meals in U.S. schools ("competitive foods"), but their current nutritional quality and compliance with national Smart Snacks standards are unknown. This study assessed competitive foods in a national sample of 90 middle and high schools. Differences in compliance by school characteristics were measured using mixed methods analysis of variance. Overall, 80% of the schools in the sample sold competitive foods; but they were less commonly available in schools with universal free school meal (UFSM) policies. A total of 840 unique products were documented and, on average, 75% were compliant with Smart Snacks standards. A total of 56% aligned with recommended added sugar limits (<10% of calories); and 340 unique products (40%) aligned with both sugar and Smart Snacks standards. Approximately one-fifth of competitive foods contained synthetic dyes, and 31% of beverages contained artificial sweeteners. Smart Snacks standards compliance was greater when competitive foods were overseen by food service departments, in comparison with others (e.g., principals, student organizations, or outside vendors [77% vs. 59% compliance; p = 0.003]). Therefore, district wellness policies should consider requiring food service departments to oversee competitive foods. Federal and state policies should limit added sugars, artificial sweeteners, and synthetic dyes. This appears to be highly feasible, given the substantial number of products that meet these criteria. UFSM policies should also be considered to support healthier school meal environments more broadly.

Nutrient Content and Compliance with Sodium Standards in Elementary School Meals in the United States Pre- and Post-COVID-19.

Various federal policies have weakened school meal nutrition standards in the United States since the passage of the Healthy, Hunger-Free Kids Act in 2010, including temporary school meal nutrition waivers to promote post-COVID-19 pandemic recovery. This study used school menu and nutrient data from a nationally representative sample of 128 elementary school districts to examine differences in nutrients (average calories, total fat, saturated fat, sodium, total sugar, and fiber) and alignment with United States Department of Agriculture (USDA) sodium targets in 2019 (pre-pandemic) and in 2022 (post-pandemic). Data were analyzed using analysis of variance accounting for repeated measures within school districts, adjusting for geographic region and urbanicity. Small differences in the nutrient content for both breakfast and lunch were observed between 2019 and 2022. Most weeks met USDA sodium Target 1 for breakfast (≥95% of weeks) and Target 1 (≥96% of weeks) and Target 1A for lunch (≥92% of weeks) in both 2019 and 2022, although compliance decreased slightly when condiments were included. Additionally, meals provided on average 57 g of total sugar. Overall, many meals are already in alignment with lower sodium targets. Simple strategies, such as offering lower sodium condiments, can further reduce sodium in school meals. The total sugar levels observed highlight that the USDA should consider limits on added sugars in school meals.

Lysine methyltransferase 2D regulates muscle fiber size and muscle cell differentiation.

Kabuki syndrome (KS) is a rare genetic disorder caused primarily by mutations in the histone modifier genes KMT2D and KDM6A. The genes have broad temporal and spatial expression in many organs, resulting in complex phenotypes observed in KS patients. Hypotonia is one of the clinical presentations associated with KS, yet detailed examination of skeletal muscle samples from KS patients has not been reported. We studied the consequences of loss of KMT2D function in both mouse and human muscles. In mice, heterozygous loss of Kmt2d resulted in reduced neuromuscular junction (NMJ) perimeter, decreased muscle cell differentiation in vitro and impaired myofiber regeneration in vivo. Muscle samples from KS patients of different ages showed presence of increased fibrotic tissue interspersed between myofiber fascicles, which was not seen in mouse muscles. Importantly, when Kmt2d-deficient muscle stem cells were transplanted in vivo in a physiologic non-Kabuki environment, their differentiation potential is restored to levels undistinguishable from control cells. Thus, the epigenetic changes due to loss of function of KMT2D appear reversible through a change in milieu, opening a potential therapeutic avenue.

Prenatal and perinatal history in Kabuki Syndrome.

Kabuki syndrome (KS) is a disorder of epigenetic dysregulation due to heterozygous mutations in KMT2D or KDM6A, genes encoding a lysine-specific methyltransferase or demethylase, respectively. The phenotype is highly variable, including congenital cardiac and renal anomalies, developmental delay, hypotonia, failure to thrive, short stature, and immune dysfunction. All affected individuals have characteristic facial features. As KS natural history has not been fully delineated, limited information exists on its prenatal and perinatal history. Two tertiary centers collected retrospective data from individuals with KS (N = 49) using a questionnaire followed by review of medical records. Data from 49 individuals (age range: 7 months-33 years; 37% male; 36 with KMT2D mutations, 2 with KDM6A mutations, and 11 diagnosed clinically) were examined. Polyhydramnios affected 16 of 39 (41%) pregnancies. Abnormal quad screens in four out of nine (44%) pregnancies and reduced placental weights also complicated KS pregnancies. These data comprise the first large dataset on prenatal and perinatal history in individuals with confirmed (genetically or clinically) KS. Over a third of pregnancies were complicated by polyhydramnios, possibly secondary to abnormal craniofacial structures and functional impairment of swallowing. The differential diagnosis for polyhydramnios in the absence of intrauterine growth retardation should include KS.

Holoprosencephaly in Kabuki syndrome.

Kabuki syndrome is a rare, multi-systemic disorder of chromatin regulation due to mutations in either KMT2D or KDM6A that encode a H3K4 methyltransferase and an H3K27 demethylase, respectively. The associated clinical phenotype is a direct result of temporal and spatial changes in gene expression in various tissues including the brain. Although mild to moderate intellectual disability is frequently recognized in individuals with Kabuki syndrome, the identification of brain anomalies, mostly involving the hippocampus and related structures remains an exception. Recently, the first two cases with alobar holoprosencephaly and mutations in KMT2D have been reported in the medical literature. We identified a de novo, pathogenic KMT2D variant (c.6295C > T; p.R2099X) using trio whole-exome sequencing in a 2-year-old female with lobar holoprosencephaly, microcephaly and cranio-facial features of Kabuki syndrome. This report expands the spectrum of brain anomalies associated with Kabuki syndrome underscoring the important role of histone modification for early brain development.
