Background: There is a potential role of choline in cardiovascular and cerebrovascular disease through its involvement in lipid and one-carbon metabo

The two goals of this study are to examine the impact of an early childhood teacher’s metacognition-driven, place-based science teaching professional development (PD) intervention and to explore the association between science teaching and environment quality and children’s self-regulated learning. A total of 110 children (Mage = 60 months) and 20 teachers from preschools and kindergartens in rural regions of Idaho, U.S., participated in this mixed-methods study between August 2022 and May 2023. Children’s and teachers’ pre-test and post-test data were collected using validated observation tools, surveys, and reflection journals. The results from repeated measures ANOVA and linear mixed regression show that there were statistically significant increases in children’s self-regulated learning scores and teachers’ science teaching efficacy and metacognitive knowledge, but not metacognitive regulation skill scores post-PD. Thematic analysis revealed evidence about children’s learning interests and inquiry skills, and that science activities supported children’s learning in other subjects and developmental domains (e.g., literacy, mathematics, and social-emotional skills). Our results indicate the potential for supporting young children’s self-regulated learning by training teachers to implement a developmentally appropriate, hands-on science curriculum that focuses on reflective thinking and a holistic understanding of science concepts and process skills.

Collegiate dance is unique because it requires athletic and academic performance; therefore, optimizing physical and mental function is crucial. Research among athletic populations demonstrate improvements in body composition, performance, and cognition following creatine monohydrate (CR) supplementation, yet dancers have not been investigated. The purpose of this study was to determine the effects of CR supplementation on body composition, performance, and cognitive function in female collegiate dancers. Participants were randomized to CR (CR; n = 7; 0.1 g·kg −1·day −1 CM +0.1 g·kg −1·day −1 corn-starch maltodextrin) or placebo (PL; n = 6; 0.2 g·kg −1·day −1 corn-starch maltodextrin) for 42 days. Pre- and post-testing included body composition, total body water (TBW), Depression, Anxiety and Stress Scale, Diet History Questionnaire, the National Institute of Health Toolbox fluid cognition battery and isokinetic strength, vertical jump, medicine ball throw, and Wingate anaerobic power test. CR demonstrated a significant increase in TBW (pre, 32.2 ± 3.5 kg; post, 32.7 ± 3.6 kg; p = 0.024) and lean mass (LM; pre, 39.8 ± 3.6 kg; post, 41.5 ± 4.5 kg; p = 0.020). CR supplementation may be an effective strategy to increase TBW and estimates of LM in female collegiate dancers. Although this may optimize aesthetics, larger samples sizes with resistance training are needed to determine if CR supplementation increases muscle mass and translates to improved performance.

Wildland firefighters (WLFFs) perform in adverse environments making rapid adjustments to dietary needs. The National Mobile Food Services (NMFS) contract details WLFF dietary provisions on wildfire incidents. Objective: Determine the nutrient content of food and drink provided to and consumed by WLFFs under the NMFS contract. Methods: Individual (n = 122) dietary provisions and consumption was recorded during 1 workday. Nutritional analysis of items provided was compared with consumption and the recommended dietary allowance (RDA). Results: WLFFs consumed significantly (P < 0.05) fewer macronutrients than provided for calories, protein, and fat. Provided and consumed micronutrients were below the RDA for vitamins D and E, magnesium, and manganese. Conclusion: Most dietary recommendations were met by NMFS provisions. Next steps include WLFF nutrition education to improve consumption and contract revisions to meet micronutrient recommendations.

The purpose of this study was to determine how the 24-hour dietary recall (24HDR) is administered and how the Expanded Food and Nutrition Education Program (EFNEP) peer educators and other staff are trained on the data collection and entry process, from the EFNEP coordinators’ perspectives. This cross-sectional, quantitative study utilized an online survey to collect information from EFNEP coordinators representing 61 of 76 EFNEP programs. While 56% of the programs collected the 24HDR data starting with the first thing eaten the previous day, 49% of them started collecting data at the time of class, going backwards. Most programs, i.e., 72%, reported using a multiple-pass method; however, only one-third of them reported using the standard five-pass method. Almost all programs, i.e., 97%, reported one peer educator collecting data from a group of 2–12 clients. All programs reported collecting the 24HDR data in a group setting, with about one-third of the programs also collecting data one-on-one. Most programs, i.e., 57%, reported spending ≤4 h on the initial training of staff in how to collect 24HDR data, and 54% of them reported that the peer educators entered the data themselves. This study found that the methods used to collect answers, train the staff, and enter the 24HDR data varied across EFNEP programs and that there is a need to standardize or revise the collection of 24HDR data.

Protein, iron, zinc, and choline affect early brain development and are found in beef. The aims of this study were to describe (1) early feeding practices related to introduction of beef in the rural US west (Idaho); (2) parental perceptions of beef as a first food, and (3) associations between early beef consumption and child cognition at 1–5 years. A total of 61 children and their parents were enrolled. Parents completed a survey and a food frequency questionnaire to assess perceptions of beef and early feeding practices along with their child’s dietary intake at 6–12 months. Children’s cognitive function was assessed using the Bayley-4 Scales of Infant and Toddler Development (12–35 months) and the NIH Toolbox for Assessment of Neurological and Behavioral Function (NIHTB) (3–5 years). Parents introduced beef at 7.79 ± 2.65 months of age, primarily so that their children could eat what the family was eating. Higher intake of beef (r = 0.41, p = 0.02), zinc (r = 0.45, p = 0.01), and choline (r = 0.39, p = 0.03) at 6–12 months was associated with better attention and inhibitory control at 3–5 years of age. These findings support the role of beef as an early food for cognitive development, although controlled dietary intervention studies are needed.
