Self-reported fruit and vegetable (FV) consumption in children has limitations that could be overcome with objective measures that are easy to implement. The Veggie Meter (VM) is a non-invasive portable device that measures skin carotenoid levels, a concentration biomarker of usual FV intake. While VM has been used to measure FV consumption in adults, few studies have explored its use in elementary school settings. Designing research studies using the VM with elementary school-age children requires an understanding of how well this device can be used in a school setting and of the distribution of VM scores in this population. We used VM to measure skin carotenoids in a diverse sample of 143 elementary school children who also answered commonly asked questions about consumption frequency of FV the previous day. Multivariable regression was used to assess the independent association of demographic variables with VM scores. VM scores were also compared with student-reported FV intake. There was a weak but statistically significant correlation between reported frequency of total vegetable consumption the previous day and observed VM scores (r = 0.174, p = 0.042). This study provides an example of the successful use of the VM in a school setting to collect an objective measure of FV intake and provides important description of data that can inform future studies.

(1) Background: It is unknown whether parents’ perception of school meals, a determinant of student meal participation, align with the nutritional quality of meals served in schools. This study compares the healthfulness of foods offered in schools with parental perception of school meals at those same schools. (2) Method: Parents were asked to rate the healthfulness of school meals at their child’s school. Data on the types of foods offered were collected from public schools in four cities in New Jersey and matched with parent-reported data. Measures were developed to capture the presence of healthy and unhealthy items in the National School Lunch Program and the presence of a la carte offerings as well as vending machines. Multivariable analysis examined the association between parental perceptions of school meals and the school food measures after adjusting for covariates. (3) Results: Measures of the school food environment and parental perceptions were available for 890 pre-K to 12th grade students. No significant associations were observed between parental perceptions and food environment measures when examined one by one or in a comprehensive model. (4) Conclusions: Parents’ perception of the healthfulness of meals served do not align with the nutritional quality of foods offered at schools.

School food and physical activity (PA) environments can influence children's dietary and physical activity behaviors. However, evidence on whether school environment is associated with students' weight status is less definitive. In this study, we examined the association between students' body mass index (BMI) and measures of school food and PA environments. We calculated BMI from nurse-measured data collected on 19,188 6-19-year-old students from 90 public schools in four low-income cities in New Jersey in 2015-2016. Based on a questionnaire administered to school nurses, we constructed 6 food and 3 PA indices capturing the healthfulness of key dimensions in the school food and PA environment domains. Multilevel linear models, stratified by school level (elementary and secondary), examined the association between BMI z-scores and indices of the school environment. The food and PA domains were modeled separately and then combined. Joint significance of indices within each domain was tested. Analyses were conducted in 2019-2020. In the combined model for elementary schools, indices in both the food and PA domains were jointly significant (p = 0.005 and p < 0.001, respectively). With regard to specific indices in the model, students' BMI z-score was 0.03 units lower for each additional outdoor PA facility (95% CI [-0.06, -0.00]; p = 0.036). Similarly, for secondary schools, both the food and PA domains were jointly significant (p = 0.004 and p = 0.020, respectively). Each additional unhealthy item in vending machines was associated with a 0.12 unit increase in BMI z-score (95% CI [+0.00, 0.23]; p = 0.042). Overall, healthier food and PA environments were associated with lower student BMI.

To support families during the COVID-19 pandemic, the USDA allowed all US schools to offer meals at no cost regardless of family income, a policy referred to as Universal Free Meals or Healthy School Meals for All (HSM4A). Despite the recognized benefits and popularity of HSM4A during the pandemic, the policy expired in June 2022. The goal of this study was to gather perceptions of parents in Arizona about school meals, the HSM4A program, and the discontinuation of HSM4A. In collaboration with a local anti-hunger group, using an online survey distributed in September and October 2022, we collected data from a diverse sample of over 2000 parents living in Arizona. Parents unequivocally supported HSM4A during the pandemic (97%) and expressed support for continuing to offer HSM4A (95%). High levels of support were seen across all groups in the study, including from individuals who identified as politically conservative. We also analyzed 750 responses to an open-ended question asking respondents to share their thoughts about offering meals to all Arizona students regardless of family income. The majority of emergent themes related to perceived benefits of HSM4A, including reducing financial burden and stress for families. Our findings will be useful for advocates and policy makers considering HSM4A legislation.
