RESUMEN

INTRODUCTION: US Department of Agriculture (USDA) Gus Schumacher Nutrition Incentive Programme (GusNIP) produce prescription programme (PPR) 'prescriptions' provide eligible participants with low income, risk for diet-related chronic disease and food insecurity a healthcare issued incentive to purchase lower to no cost fruits and vegetables (FVs). However, GusNIP requirements specify that PPR prescriptions can only be redeemed for fresh (not frozen, canned or dried) FVs. This requirement may prevent participants from fully engaging in or benefiting from GusNIP PPR, given communities with lower healthy food access may have reduced fresh FV accessibility. METHODS AND ANALYSIS: We will use the nationally representative 2012-2013 National Household Food Acquisition and Purchase Survey (FoodAPS) and complementary FoodAPS Geography Component data in a secondary data analysis to examine how household GusNIP PPR eligibility relates to the quantity and variety of fresh, frozen, canned and dried FV purchases and to what extent individual, household and food environment factors shape the relationship. FoodAPS data include household food purchasing and acquisition information across a 7 day period from 14 317 individuals among 4826 households and was collected between April 2012 and January 2013. The FoodAPS Geography Component provides information about the local community/environment relative to FoodAPS households. This study will examine the correlation or association of selected variables between different quantities and varieties of fresh, frozen, canned and dried FVs, as well as correlations among multilevel predictors. ETHICS AND DISSEMINATION: We are following data integrity standards as outlined by agreements with the USDA Economic Research Service. All results of analyses will undergo a thorough disclosure review to ensure no identifiable data are shared. Results will be disseminated to research, practice and policy communities using an Open Access peer-reviewed manuscript(s), scientific and practice presentations, and a public facing report and infographic.

RESUMEN

As Lebanon's economic crisis become uncontrollable, Lebanese pregnant women face malnutrition, with many having to skip meals and switch to resort to cheap and unhealthy alternatives altogether. The objectives of the study were to assess the dietary and lifestyle patterns of Lebanese pregnant women and to evaluate their diets compliance with the United States Department of Agriculture (USDA) pregnancy recommendations, before and during the Lebanese escalating economic crisis. A cross-sectional study was conducted between April 2021 and January 2022. A validated self-administrated questionnaire was administered during the first, second and third trimesters of pregnancy among 363 women in all Lebanese governorates. Most of the pregnant women were free of diseases. While the majority did not smoke, 14.1% smoked hookah / shisha during pregnancy. The adherence to the USDA recommendations in our sample did not significantly vary prior to and throughout the socioeconomic crisis, and it was generally low. Only the mean consumption of vegetables increased during the socioeconomic crisis (p<0.05). Regarding physical activity, while the proportion of active women slightly decreased during the socioeconomic crisis, around 55% were still active. In conclusion, higher attention should be given to the dietary habits and health of this critical population, through effective interventions that increase awareness and achieve measurable improvements.

RESUMEN

Cowpea (Vigna unguiculata L. Walp) is an important grain legume crop of the subtropics, particularly in West Africa, where it contributes to the livelihoods of small-scale farmers. Despite being a drought-resilient crop, cowpea production is hampered by insect pests, diseases, parasitic weeds, and various abiotic stresses. Genetic improvement can help overcome these limitations, and exploring diverse cowpea genetic resources is crucial for cowpea breeding. This study evaluated the genetic diversity of 361 cowpea accessions from the USDA core collection for the species using 102 Kompetitive Allele Specific PCR (KASP) single nucleotide polymorphism (SNP) markers. A total of 102 KASP-SNP was validated in the germplasm panel, and 72 showed polymorphism across the germplasm panel. The polymorphism information content (PIC) of all SNPs ranged from 0.1 to 0.37, with an average of 0.29, while the mean observed heterozygosity was 0.52. The population structure revealed three distinct populations that clustered into two major groups after phylogenetic analysis. Analysis of molecular variance (AMOVA) indicated greater genetic variation within populations than among populations. Although cowpea generally has a narrow genetic diversity, the accessions used in this study exhibited considerable variation across geographical regions, sub-species, and improvement status. These results indicated that the selected KASP genotyping assay can provide robust and accurate genotyping data for application in the selection and management of cowpea germplasm in breeding programs and genebanks.

RESUMEN

The Dietary Guidelines for Americans (DGA) provides science-based advice on dietary intake to promote health, reduce risk of chronic disease, and meet nutrient needs. It is jointly published by the United States Departments of Health and Human Services and Agriculture (USDA) every 5 y. As chronic diseases continue to rise to pervasive levels, helping the United States population follow the DGA is especially important for improving the health of our nation. The DGA is developed using a rigorous and transparent scientific process, and with the advice of an independent, external committee of leading scientists. Career federal nutrition scientists who manage the process ensure that the methods used to develop the DGA remain state of the art. Unfortunately, misinformation about the scientific basis, transparency, and relevance of the DGA for the United States population threatens its credibility. The main objective of this article is to correct this misinformation with factual information about the process used to develop the DGA. The DGA provides guidelines for the general public, and its primary audience includes policymakers and nutrition and health professionals who help individuals and families consume a healthy dietary pattern. Providing accurate information may bolster trust in the recommendations among these audiences while improving implementation across sectors to promote better adherence to the DGA, thereby improving diet quality among the United States population.

RESUMEN

BACKGROUND: Districts with federal nutrition programs must have an updated local school wellness policy (LSWP) to promote nutrition, physical activity, and student wellness. This study evaluates factors associated with LSWP quality among low-income districts. METHODS: In 2018, we collected LSWPs from websites of 200 randomly selected, county-stratified, low-income-serving California public districts. Multivariable linear regression assessed associations between district characteristics, model LSWP use (national, state, none), and adoption date on policy quality. RESULTS: On the WellSAT 3.0 scale of 0-100, mean (95% CI) comprehensiveness was 65.0 (63.2-66.7) and strength was 37.3 (35.3-39.2). Nearly verbatim adoption of model LSWPs was high (68.5% state model, 13.0% a national model). Half were adopted before mandated updates. District size (≥1000 students) and national model LSWP adoption were associated with higher comprehensive scores. National model LSWP adoption was associated with higher strength scores in updated policies compared with those not updated. IMPLICATIONS: LSWPs have improved school food and activity environments, but district engagement in LSWP is low. Integration into education frameworks that reduce learning barriers could provide synergy for re-engagement. CONCLUSIONS: High adoption of model policies and low update compliance indicate little district engagement in LSWP. Mixed methods studies of districts with high-quality LSWP are needed.

RESUMEN

BACKGROUND: The US Department of Agriculture's school meal programs have wide reach during the school year, but food insufficiency among households with children increases during summer months. The US Department of Agriculture summer meal programs are designed to fill this gap, yet participation has historically been low. OBJECTIVE: To examine the facilitators and barriers to participation in a 2021 summer meal program while the COVID-19 pandemic regulation waivers were in place. DESIGN: Cross-sectional mixed-methods survey research. PARTICIPANTS/SETTING: All parents/guardians of children enrolled in a school district in Connecticut were invited to participate in an online survey in December 2021. The respondents included summer meal participants (n = 622) and nonparticipants (n = 294). MAIN OUTCOME MEASURES: Survey respondents reported demographic variables, current food sufficiency, communication preferences, satisfaction with the program, reasons for using or not using the program, and whether they found the program helpful financially. The survey included three open-ended questions about barriers to participation. RESULTS: Respondents who used the summer meal program indicated that the pandemic-related regulatory waivers were key to their decision to participate. Reported barriers included lack of awareness of the program, inability to travel to sites during the times they were open, lack of transportation, concerns about dietary restrictions, and lack of variety in the menu, and concerns about wasting food. Parents/guardians expressed strong preferences for receiving communication about summer meals directly from their child's school and being able to access meals outside of typical work hours. CONCLUSIONS: The pandemic waivers allowed sponsors to test different models of distribution. Parents/guardians responded positively to the opportunity to access grab-and-go meals, multiple meals at once, and meals without a child present. These findings can be used to inform potential policy changes to reduce barriers and increase participation.

RESUMEN

BACKGROUND: Although research shows that children from households with low incomes have diet quality that is better during the school year vs the summer, very little research exists around the nutritional quality of summer meals available to children through the US Department of Agriculture's (USDA) summer meals programs. OBJECTIVE: The objective was to examine the extent to which summer meals contributed to meeting the daily nutritional goals from the 2015-2020 Dietary Guidelines for Americans (DGAs) for 9- to 13-year-olds. The current study also analyzed the types of food offered and the top food sources of energy and nutrients in summer lunches. DESIGN: This cross-sectional study analyzed a nationally representative sample of summer meal sites participating in the Summer Food Service Program (SFSP) or the Seamless Summer Option (SSO). SETTING: Weekly lunch menus were obtained from 731 summer meal sites operating in the summer of 2018 (SFSP sites: n = 578; SSO sites: n = 153). MAIN OUTCOME MEASURES: Outcome measures included the most frequently offered foods in the major food groups. The energy and nutrient content of lunches offered were estimated and compared with the daily nutritional goals provided by the 2015-2020 DGAs for 9- to 13-year-olds. STATISTICAL ANALYSES PERFORMED: Menu data were entered into USDA's SurveyNet and linked to the USDA's Food and Nutrient Database for Dietary Studies 2015-2016. Foods were classified into major and minor food groups from the USDA's School Nutrition and Meal Cost Study. The energy and nutrient values were compared with the daily nutritional goals provided by the DGAs for children ages 9 to 13 years. RESULTS: Summer lunches provided substantial contributions toward the daily goals for energy and nutrients for 9- to 13-year-olds. SSO programs provided significantly more vegetables than SFSP programs (P < 0.05) and contained significantly higher amounts of vitamins A (P < 0.05), C (P < 0.05), and iron (P < 0.05). Sodium amounts were below the daily limit for 9- to 13-year-olds across both program types. CONCLUSIONS: Although SSO lunches offered more vegetables than SFSP lunches, lunches served in both SSO and SFSP contributed substantially toward the daily goals for energy and nutrients.

RESUMEN

Thirty-three USDA Select boneless top loins were selected from carcasses at a commercial major packing plant, vacuum-packaged, and aged for 14 d (4 °C). The loins were then divided into 10 portions (5 grill temperatures for each of trained sensory panel and Warner-Bratzler shear force). Flat-top electric grills were pre-heated to 1 of 5 different temperatures: 149 °C (149), 177 °C (177), 204 °C (204), 232 °C (232), or 260 °C (260). Steaks were placed on the grill, turned when the internal temperature reached 35 °C and removed when the internal temperature reached 71 °C. A trained sensory panel evaluated ten basic flavors and five texture attributes. Extra cubes from each sample were frozen in liquid nitrogen and stored at -80 °C for GC/MS volatile aroma compound analysis. Beef identity, brown, and roasted flavor descriptors increased linearly (P < 0.001) while bloody/serumy tended to decrease (P = 0.016) and sour flavor decreased (P = 0.006) linearly as grill temperature increased. Furthermore, burnt (deviation P = 0.008) and bitter (deviation P = 0.012) flavor descriptors were affected by effects other than linear or quadratic, while umami (P = 0.002) and overall sweet (P = 0.016) flavors increased quadratically from 149 to 232 then declined at 260 grill temperatures. Two alcohols, eight aldehydes, four alkanes, three furans, eight ketones, and twelve pyrazines were impacted by differences the grill temperature. Increasing grill temperature increases volatile compounds, primarily from the Maillard reaction, that improve positive beef flavor descriptors.

RESUMEN

New imaging technologies to identify food can reduce the reporting burden of participants but heavily rely on the quality of the food image databases to which they are linked to accurately identify food images. The objective of this study was to develop methods to create a food image database based on the most commonly consumed U.S. foods and those contributing the most to energy. The objective included using a systematic classification structure for foods based on the standardized United States Department of Agriculture (USDA) What We Eat in America (WWEIA) food classification system that can ultimately be used to link food images to a nutrition composition database, the USDA Food and Nutrient Database for Dietary Studies (FNDDS). The food image database was built using images mined from the web that were fitted with bounding boxes, identified, annotated, and then organized according to classifications aligning with USDA WWEIA. The images were classified by food category and subcategory and then assigned a corresponding USDA food code within the USDA's FNDDS in order to systematically organize the food images and facilitate a linkage to nutrient composition. The resulting food image database can be used in food identification and dietary assessment.

RESUMEN

OBJECTIVE: The goal of this scoping review is to examine the published research on federal nutrition assistance programs administered by the United States (U.S.) Department of Agriculture during the COVID-19 pandemic, in the U.S., U.S. territories, and tribal nations. The review will identify the scope of the available research and provide research and policy recommendations. INTRODUCTION: The COVID-19 pandemic made individuals more vulnerable to experiencing food insecurity. Federal nutrition assistance programs help to address food insecurity and have been rapidly adapting to meet food and nutrition needs among affected communities during the COVID-19 pandemic. It is important to understand the scope of the current research on this topic to help inform future research, practice, and policy recommendations. INCLUSION CRITERIA: This review will include studies focused on federal nutrition assistance programs administered by the U.S. Department of Agriculture during the COVID-19 pandemic. The scoping review will consider all primary research designs. METHODS: Pubmed, CINHAL, Scopus, and Proquest's Health Management databases will be used for the literature search. Only articles published in English since March 1, 2020 will be considered. Titles/abstracts followed by full-text articles will be reviewed to determine which articles meet the inclusion criteria and should be included in the review. Data will be extracted from each included article using a data extraction template in Covidence that will be developed by the study team. Data extracted will include information on key findings related to the review questions. At each step, two independent reviewers will be assigned to each article. Data will be summarized and presented in tables, charts, and narrative summary.

RESUMEN

BACKGROUND: Participation in the US Department of Agriculture's summer meals program is consistently lower compared to National School Lunch Program (NSLP) participation, even though the programs target the same population of children. The purpose of this study was to elucidate reasons for participation and nonparticipation in the summer meals program. METHODS: A nationally representative sample of 4688 households with children ages 5 through 18 years living near a summer meals site in 2018 completed a survey about their reasons for participation or nonparticipation in the summer meals program, features that would help nonparticipants to attend, and household food security status. RESULTS: Almost half of all households living near a summer meal site were food insecure (45%) and most (77%) had incomes at or below 130% of the federal poverty level. Most participant caregivers (74%) sent their children to summer meal sites for the free meals, while 46% of nonparticipant caregivers said they did not attend because they were unaware of the program. CONCLUSIONS: Despite a high level of food insecurity among all households, the most reported reason for not attending the summer meals program was unawareness of the program. These findings highlight a need for better program visibility and outreach.

RESUMEN

Fusarium wilt caused by Fusarium oxysporum f. sp. niveum (Fon) race 2 is a serious disease in watermelon and can reduce yields by 80%. Genome-wide association studies (GWAS) are a valuable tool in dissecting the genetic basis of traits. Citrullus amarus accessions (n = 120) from the USDA germplasm collection were genotyped with whole-genome resequencing, resulting in 2,126,759 single nucleotide polymorphic (SNP) markers that were utilized for GWAS. Three models were used for GWAS with the R package GAPIT. Mixed linear model (MLM) analysis did not identify any significant marker associations. FarmCPU identified four quantitative trait nucleotides (QTN) on three different chromosomes (i.e., chromosomes 1, 5, and 9), and Bayesian-information and linkage-disequilibrium iteratively nested keyway (BLINK) identified one QTN on chromosome 10 as significantly associated with Fon race 2 resistance. FarmCPU identified four QTN that explained 60% of Fon race 2 resistance, and the single QTN from BLINK explained 27%. Relevant candidate genes were found within the linkage disequilibrium (LD) blocks of these significant SNPs, including genes encoding aquaporins, expansins, 2S albumins, and glutathione S-transferases which have been shown to be involved in imparting resistance to Fusarium spp. Genomic predictions (GP) for Fon race 2 resistance using all 2,126,759 SNPs resulted in a mean prediction accuracy of 0.08 with five-fold cross-validation employing genomic best linear unbiased prediction (gBLUP) or ridge-regression best linear unbiased prediction (rrBLUP). Mean prediction accuracy with gBLUP leave-one-out cross-validation was 0.48. Thus, along with identifying genomic regions associated with Fon race 2 resistance among the accessions, this study observed prediction accuracies that were strongly influenced by population size.
