Culinary Skills Intervention: Immediate Impacts on Knowledge, Attitudes and Self‐Efficacy in Adolescent Youth
Authors: Oakley Amanda R. , Nickols‐Richardson Sharon M. 
Published: November 2023

Childhood obesity continues to be a public health concern in the United States. Youth acceptability of foods is higher when adolescents prepare a food item themselves, rather than consuming the same food prepared by someone else. Yet, many adolescents do not have any culinary skills or have had only minimal cooking experiences. The aim of this study was to conduct and evaluate a culinary skills intervention for adolescent youth as part of a childhood obesity prevention program. Adolescents [6th–7th grade, aged 12.1 ± 1.1 years (mean ± SD)] were randomized to adult‐led (n = 20) or peer‐led (n = 22) intervention groups. Participants attended two, 2‐hour culinary skills lessons where cutting techniques, cooking methods and following recipes were addressed. Questionnaires were administered pre‐ and post‐intervention to measure changes in knowledge (score = 0–19), attitudes (score = 0–55), cooking self‐efficacy (score = 0–50) and cooking methods self‐efficacy (score = 0–35) regarding lesson topics. Each correct knowledge response was assigned one point, and points were totaled for the overall score. Attitude and self‐efficacy measures were recorded on a 5‐point Likert scale then totaled for an overall categorical score. Independent and paired t‐tests were used to analyze differences between groups and within groups, respectively (SPSS, version 22.0). Significance was set at P < 0.05. There were no significant differences in the pre‐ to post‐intervention change in knowledge, attitudes and self‐efficacy between intervention groups. All adolescents (n = 42) increased their scores in knowledge [3.7 ± 2.6 (mean ± SD), P < 0.001] and attitudes (2.1 ± 4.1, P < 0.003) of culinary skills and in cooking self‐efficacy (7.7 ± 4.9, P < 0.001) and cooking method self‐efficacy (6.6 ± 5.1, P < 0.001) directly following the intervention. A culinary skills intervention resulted in immediate positive improvements in knowledge, attitudes and self‐efficacy regarding culinary skills in a group of adolescents. Mode of intervention (i.e., peer‐ vs. adult‐led) did not significantly impact these outcomes.Support or Funding InformationThis material is based upon work that is supported by the National Institute of Food and Agriculture, U.S. Department of Agriculture, under award number 2012‐68001‐22032.

Published: November 2023

Historically, the study of consumer attitudes and beliefs about food have relied heavily on self‐reported data using survey and interviewing methodologies. Opinion mining of social media data may be an effective method for collecting and evaluating real‐time attitudes regarding food choice and dietary intake patterns. This study was a post‐hoc analysis of geographical tweets across the continental United States to assess attitudes toward dairy products. Between the years August, 2013 – June, 2015, 232628 geo‐located tweets were collected from the social media application, Twitter, using the following keywords: dairy, milk, cheese, yogurt and kefir. Natural language processing techniques including, topic extraction and sentiment analysis were used to analyze the data. Latent Dirichlet Allocation (LDA) models were used to establish contextual probabilities for discussion topics and account for different contexts by state and geographical region (South, North East, West and Mid‐West). Sentiment analysis of each tweet was completed using the Stanford CoreNLP, SentiStrength and SentiWordNet toolkits and sentiment values were combined to assign an overall sentiment score. Negative and positive sentiment scores were assigned to each tweet based on a scale from −1 to 1. Principal components analysis was used to assess the significance of tweet topics for all states. Five major topics were identified from these analyses: milk, dairy queen, cheese, chocolate milk and yogurt. Tweet topics relating to milk and cheese were the most common topics throughout the United States with even distributions across the four country regions. Cheese‐related topics were twice as common as chocolate milk tweets across all states; this trend was also apparent in the analysis by region. Yogurt was mentioned more frequently in the West while Dairy Queen was more commonly mentioned in Mid‐West and Southern regions. Tweet topics from the District of Columbia differed from other states with significantly more mentions of chocolate, cheese and yogurt. Wyoming and Montana had the lowest overall significance values for major identified topics. Sentiment analyses revealed that cheese‐related topics received mixed attitudes while chocolate milk was positively discussed across the United States. Dairy Queen mentions were very positive but discussion of yogurt was slightly more negative in the East when compared to the West. Overall, Twitter discussions of dairy foods were positive but regional differences were noted for yogurt. Social media mining provides a novel method of studying food attitudes and behaviors in real time. Such analyses may be beneficial for public health and policy initiatives and allow health/nutrition educators to more adequately address region‐ and state‐specific feelings about foods and beverages.Support or Funding InformationN/A

Published: November 2023

PurposeThis study was designed to evaluate whether overexpression of inflammatory mediators induced in the liver by repeated intense exercise could be prevented by quercetin and whether the protective effect of quercetin was related with inhibition of nuclear factor kappa B (NF‐κB) activation.MethodsAdult male BALB/C mice were treated by quercetin (100 mg/kg.bw.) for 4 weeks and subjected to the exercise protocol on a treadmill (28 m/min at 5° slope for 90 min) of 7 consecutive days concurrently at the fourth week.ResultsIntense exercise for mice resulted in the leakage of aspartate and alanine aminotransferases and ultrastructural malformation mainly evidenced by swollen and degenerative changes, which was overtly attenuated by quercetin prophylaxis. Both serous and hepatic mRNA levels of IL‐1β, IL‐6, and IL‐10 and serous TNF‐α were markedly elevated. Intense exercise was also associated with a significant increase in inducible nitric oxide synthase, cyclooxygenase‐2, and intercellular adhesion molecule‐1 protein levels. And these effects were totally or partially prevented by quercetin precondition. Furthermore, quercetin regime evidently alleviated activation and nuclear translocation of NF‐κB by inhibiting phosphorylation of IKKα and Iκbα in the liver of intense exercise mice.ConclusionQuercetin protects mouse liver against intense exercise damage, and impaired production of noxious mediators involved in the inflammatory process and down‐regulation of the NF‐κB signal transduction pathway appear to contribute to the beneficial anti‐inflammatory effects of quercetin, highlighting a promising strategy for over‐training injury by naturally occurring phytochemicals.Support or Funding InformationThis work was supported by the National Natural Science Foundation of China (No. 81172658) and Program for New Century Excellent Talents in University of China (NCET 08‐0222).
Food Insecure Women with Lower Education Report More Health Problems in a Global Sample of Individuals
Authors: Dallmann Diana , Miller Meghan , Melgar‐Quiñonez Hugo 
Published: November 2023

Because of its intimate relationship with an insufficient dietary intake of nutrients essential for a healthy and active life, food insecurity (FI) is associated with a wide range of physical and mental health issues. Education is linked with better health through multiple pathways, including job prospects and income, risk for disease, intra‐generational effects, and behavioral and social factors. In most societies, especially in developing countries, women are more vulnerable than men to FI and to poor education levels. The present research uses the Food Insecurity Experience Scale (FIES) in the Gallup World Poll (GWP) to examine the impact of FI and education on self‐reported health status across nationally representative samples from 140 countries.This study aimed to ascertain the effects of FI, gender, and education on the likelihood that participants report health problems (HP). It also explored potential interactions in their effect on health.Data from the 2014 GWP were analyzed using IBM SPSS 21 with the Complex Samples module. One question regarding the presence of HP was selected as the outcome of interest. FI was assessed using the 8‐item FIES, considering food insecure (fi) individuals to be those who answered affirmatively to at least one questionnaire item. Multivariable logistic regression analysis was used to determine the effect of the interaction term of FI, education and gender on HP. The model was adjusted for age, income, water quality, and household size. Data was weighted by country population size.The sample included 136,667 individuals, of which 50.1% were female, 24.9% reported having a HP, and 45.3% were fi. Regarding education, 45.4% completed elementary education or less, 46.1% completed up to three years of tertiary education, and 8.5% completed four years beyond ‘high school’ and/or received a college degree. The interaction term (FI, education, and gender) was statistically significant (p < 0.001).When compared to food secure men with the highest education level, fi women with low education level presented the highest odds of reporting HP (OR=5.2).Results reveal increased vulnerability to HP among women, fi individuals, and those with lower education levels, providing evidence that health is determined not only by internal factors as genetics or external ones such as healthy lifestyle, but also by social factors. These social determinants are important to take into account in health‐related policy decisions and program design.

Published: November 2023

BackgroundUS children do not consume enough calcium, vitamin D, potassium, and fiber. Milk is a frequently consumed food that provides several nutrients that support growth and development for children and adolescents, thus may be associated with nutrient adequacy. However, previous evidence suggests milk intake has decreased in the past two decades among children and adolescents. An investigation of how milk drinking behavior may be related to dietary quality among US children and adolescents is important to implement future dietary recommendations and interventions.ObjectiveTo estimate and compare the nutrient intake of US children and adolescents by milk drinking behavior, using data collected from the National Health and Nutrition Examination Survey (NHANES), 1999–2012.MethodsChild and adolescent participants (1–19 yrs; n=25,183) with a reliable 24‐hour dietary recall(s) were included in this cross‐sectional study. Dietary intake was assessed using a 24‐hour dietary recall(s) and linked with the USDA Food and Nutrient Database for Dietary Studies (FNDDS) to quantify nutrient intake. Milk drinking behavior was quantified based on responses to the dietary behavior questionnaire. Usual intakes of nutrients were estimated using the National Cancer Institute statistical modeling (NCI method). Meeting requirements of the Dietary Reference Intake (DRI) or not was compared by milk drinking behavior using logistic regression.ResultsThe odds of meeting the DRI requirements for calcium, iron, magnesium, zinc, Vitamin E, Vitamin A, Vitamin C, Vitamin D, Vitamin B‐6, Vitamin B‐12 and folate were significantly higher for children and adolescents who consumed milk on a daily basis compared with those who had varied or less milk drinking behavior. Children consuming milk on a daily basis met the DRI requirements more prevalently compared with those who did not (p<0.05).ConclusionMilk drinking behavior is a useful indicator of nutrient adequacy associated with nutrient gaps among US children and adolescents. Dietary interventions aimed at improving milk consumption may be especially critical for improving nutrient intake among children.Support or Funding InformationFunding: This project was supported with a grant from Elanco.

IntroductionSleep disturbance is associated with diabetes risk. Household food insecurity disproportionately affects Latinos and is a novel risk factor for disturbed sleep. Psychological distress may be a potential mechanism through which food insecurity affects sleep, so we tested the relationships between these factors, and whether psychological distress mediates the relationship between HFI and sleep.ApproachWe recruited Latinos with type 2 diabetes (N=121) for the CALMS‐D stress management trial who completed the US Household Food Security Scale (USHFSS), and measures of depressive symptoms (PHQ‐8), anxiety symptoms (PROMIS‐short), diabetes distress (PAID‐5), and sleep quality (Pittsburgh Sleep Quality Index; PSQI) at baseline. Psychological distress was operationalized with the PHQ‐8, PROMIS‐short and PAID‐5. We used unadjusted and adjusted indirect effect tests with bias‐corrected bootstrapped confidence intervals on 10,000 samples to test both the relationships between variables and for mediation.ResultsMean age was 61 years, 74% were females and 67% were food insecure. Greater household food insecurity was associated with both greater psychological distress and worse sleep quality (all, p<.05). Depressive symptoms (adj. coeff.=2.22, CI:1.27–3.42), anxiety symptoms (adj. coeff.=1.70, CI:.87–2.85), and diabetes distress (adj. coeff.=.60, CI:.11–1.32), each mediated the relationship between greater household food insecurity and worse sleep quality with and without adjustment for age, education, income, marital status, and employment status.ConclusionsFood insecurity is a common and potent household stressor associated with suboptimal sleep quality through psychological distress. Efforts to improve food security and psychological distress may yield improved sleep in this high‐risk population.Support or Funding InformationThis work is supported by: Stress Management Among Latinos With Type 2 Diabetes (CALMS‐D) (NIMHD R01MD005879‐01).

Published: November 2023

In response to the general guidelines for the sale and distribution of food and drinks prepared and processed in the schools of the national education system in Mexico, the Universidad Iberoamericana decided to implement a strategy for monitoring the regulation.Methoda plural Council (academic staff, administrative, workers, students and chef) was formed; the nutritional composition of all food products sold in restaurants, coffee shops, fast food and vending machines were analyzed (aprox 4 000 meals/day). Expert academics trained sellers and suppliers on the prepared and packaged foods and drinks that met and or not the guidelines, considering offering greater (60%) amount of healthy products that met the guidelines and 40% of products without restriction so the student population could select having the accessibility but being free to do it (ex 40% plain water, 20% calorie sweetened drinks and 40% other beverages, plus the installation of drinkers accessible to the population to take or refill their water bottles).ResultsWithin three months, both restaurants, coffe shops and vending machines had to be adapted to the guidelines or had to leave the university. An information campaign “More flavor More health … You decide”, guided people of the changes.Conclusionsproduct sales did not decline, service employees (less social and cultural level) were the only ones who questioned the strategy; students showed no complaints. The strategy was successful in incorporating the whole university staff to the project and provide healthier food to the population.
Visualizing Microaggression in the Developing Embryo: Competition Between the Neural Crest and Endothelial Cells
Authors: Kulesa Paul 
Published: November 2023

Neural crest and endothelial cell migration events shape critical neural, skeletal and vascular structures in the developing vertebrate head. Yet, the dynamic interplay of these two cell populations has remained unclear due to a lack of in vivo imaging tools. Here, we use dynamic in vivo imaging to simultaneously observe the individual behaviors of fluorescently marked cranial neural crest cells within Tie1 transgenic quail embryos that express H2B‐EYFP in all endothelial cells. Time‐lapse recordings show that cranial neural crest and endothelial cells share common migratory pathways, physically interact, and may move in opposing directions to reach distinct targets. We use cell tracking and quantitative analyses of cell trajectories to characterize the sequence of cell interactions and associated dynamic parameters. To understand the molecular underpinnings of this complex ballet, we examine the expression patterns and functional role of anti‐angiogenic factors expressed by lead neural crest cells using multiplexed fluorescence in‐situ hybridization and a gain‐ and loss‐of‐function approach. Together, our results offer a unique view of early neural and vascular patterning and a model mechanism for cell competition within the developing vertebrate embryo.Support or Funding InformationMary C.

Impact of Citation Network on the Diffusion of Systems Science Simulation Approaches in Health‐Related Research
Authors: Liu Shiyong , Xue Hong , Wang Youfa 
Published: November 2023

BackgroundSystems science approaches, especially simulation approaches have been widely adopted by the researchers in health fields to gain better understanding of nonlinearities and dynamics generated by complex and dynamic interplay of many factors from biology to human behaviors and policy interventions. The range of applications includes but are limited to investigate issues of non‐communicable chronic disease (e.g. obesity, cardiovascular diseases, diabetes), contagious diseases (e.g. influenza, tuberculosis, HIV), healthcare management, health policy and system reform. National Institutes of Health (NIH) has actively promoted the use of systems science, predominately system dynamics model (SDM), agent‐based model(ABM), social network analysis (SNA), and discrete event simulation(DES) in health‐related research.AimsThis study is to examine how citation network in the publications regarding application of SDM, ABM, SNA and DES to health research affect their diffusion.MethodsWe have retrieved and analyzed 3912 journal papers (English) regarding application of these four simulation approaches in health‐related research starting from year of 1963 to 2013. In this study, we employed bibliometric analysis and citation network analysis.ResultsOur results indicate that the order (from the best to the worst) of diffusion status of these simulation approaches is SNA(1963–2013), ABM(1995–2013), DES (1981–2013), and SDM(1972–2013). Our findings suggest that citation network in specific approach is one of the major driving forces for their rapid diffusion in wide areas of health fields. Results also unfold that more subgroups in the citation network effectively help expand the research areas which subsequently facilitate the diffusion of the corresponding simulation approach. Further findings show that high network centrality reinforced by some key subgroups (in certain field) and adopters (authors) does not help advance diffusion of that simulation approach in health‐related research.ConclusionsThe accelerated increase in the authors, journals, expansion in research area which rapidly boost the growth in the network of citations are jointly driving the fast diffusion of SNA, ABM, DES, and SDM in health research. Even though some challenges exist thus far, interdisciplinary and/or trans‐disciplinary research bring solution to those challenges. Based on our findings in this study, it is optimistic to claim that the diffusion of above‐mentioned systems simulation approaches in health‐related research remain active for next several decades.Support or Funding InformationFunding: NIH U54 center grant, HD070725.
School Food Policies and Practices in New York City Public Schools
Authors: Prescott Melissa Pflugh , Dixon Beth 
Published: November 2023

BackgroundThe Healthy, Hunger‐Free Kids (HHFK) Act was created to improve child nutrition in the school environment. Studies have shown challenges with implementation of the HHFK Act, but little is known about implementation in urban school districts.ObjectiveThe objectives of this study were to assess the school food policies and practices in a sample of New York City (NYC) public schools, to identify variation in implementation of the policies, and to determine barriers and consequences of implementing the policies.Design and SettingThis study consisted of direct observation of school meals, structured interviews, and document collection in eight public schools in NYC.ResultsFoods offered to students were consistent with the school district menus. Free water was made available via water fountains and water jets, but not all grade levels were permitted to use the water jets at some schools. The amount of time students have to eat lunch varied across schools, within schools, and by participation in the National School Lunch Program (NSLP). Healthy school meal practices often required increased time and staff inputs. Common challenges to school food policy implementation included lack of food storage space, limited staff, time constraints and utensil restrictions.ConclusionsThe nutrition standards required by the HHFK Act were implemented successfully in the sampled schools in this study, but unregulated aspects of the school meal environment (e.g., lunch line collection method, school staffing during meal periods, time available for lunch) influence the success of this policy. Interventions to counter mealtime constraints, improve lunch line efficiency, and promote unfamiliar healthful foods and beverages may better assist the HHFK Act and other school food and nutrition policies to achieve their goals of improving child nutrition in the school environment. Further research is needed to evaluate how challenges with HHFK Act implementation change over time.
