Background/Objectives: The rising prevalence of dietary supplement use among athletes raises concerns, given the risks associated with unnecessary or excessive use. This study evaluated the impact of a Theory of Planned Behaviour (TPB)-based online educational intervention, “Nutrition for Athletes”, on dietary supplement use among varsity athletes at a Canadian university. Methods: Thirty varsity athletes were randomized into intervention (n = 18) and control (n = 12) groups. The intervention was delivered online over four weeks and consisted of four units that covered topics related to sports nutrition, hydration in sports, dietary supplements, and risks associated with dietary supplement use. Dietary supplement use was measured at baseline and post-intervention using self-reported questionnaires. Results: The most commonly used supplements at baseline were vitamin D (57%), vitamin C (53%), sports drinks (50%), protein bars, powders, and shakes (43%), and whey protein (40%). Binary logistic regression revealed a reduced likelihood of dietary supplement use in the experimental group compared to the control group post intervention, but this difference was not statistically significant (OR = 0.18, 95% CI = 0.01 to 1.76, p = 0.14). There was also no significant change in the behaviour of dietary supplement use within the experimental group, when comparing baseline to post-intervention (OR = 0.12, 95% CI = 0.01 to 1.11, p = 0.06). Conclusions: These findings reflect the potential existence of an intention-behaviour gap. Future interventions may benefit from incorporating strategies that address control-related barriers.

This study explores the behavioral intersection of nutritional health and environmental literacy among pre-service teachers within the national higher education context. Utilizing the Sustainable Healthy Diet Index (SHED Index) for the first time in Croatia, this research systematically examines the dietary habits, lifestyle choices, and socio-cultural patterns of future educators (N = 164) at the University of Split. The survey instrument evaluated the core SHED domains, Healthy Eating (HE) and Sustainable Eating (SE), alongside supplementary indicators monitoring food logistics, hydration, and waste management. Descriptive analysis revealed moderately high standardized overall SHED scores (M = 62.86), aligning with the original normative distribution. Notably, students achieved significantly higher descriptive sub-scores in the HE domain (M = 24.68) than in the SE domain (M = 18.06). Although domestic food consumption and circular recycling practices were well integrated, critical biospheric behaviors—such as reducing animal protein, consuming legumes, purchasing organic food, and composting—remain limited by cultural resistance and municipal infrastructure deficits. Furthermore, an independent t-test indicated no significant differentiation across study levels, highlighting a potential institutional stagnation throughout the five-year teacher education program. Regression analysis demonstrated that sustainable dietary choices appear to be strongly anchored in personal health concerns rather than biospheric altruism, with healthy eating emerging as the single strongest explanatory factor for of sustainable behavior. These findings indicate that to cultivate authentic ecological literacy in the future teaching workforce, higher education curricula require a systemic redesign that explicitly links sustainability to personal well-being through localized, experiential learning.

Background/Objectives: Enteral nutrition is an essential component of care for critically ill patients, and nurses play a key role in its assessment, delivery, and monitoring. Although the Spanish version of the Persenius Scale has previously undergone translation, cross-cultural adaptation, and content validation, its structural validity has not yet been evaluated. Therefore, this study aimed to evaluate the structural validity of the Spanish version of the Persenius Scale in a sample of intensive care unit nurses in Spain. Methods: A cross-sectional study was conducted using an online questionnaire administered to intensive care unit nurses. The analytical sample included 329 participants recruited through non-probability snowball sampling. Sampling adequacy was assessed using the Kaiser–Meyer–Olkin index and Bartlett’s test of sphericity. Principal component analysis with Varimax rotation was performed to evaluate the structural validity of the instrument. Hierarchical cluster analysis was also used to examine the coherence of item grouping. Results: The Kaiser–Meyer–Olkin value was 0.88, and Bartlett’s test of sphericity was significant, supporting the suitability of the data for component analysis. A five-component solution was retained, explaining approximately 58% of the total variance. The components were organizational resources, specialized training, professional responsibility, perceived competence, and technical modality of enteral administration. Organizational resources and professional responsibility showed the most homogeneous loading patterns, whereas several technical practice items demonstrated higher uniqueness and weaker structural integration. Conclusions: The present study provides preliminary evidence regarding the internal structure of the Spanish version of the Persenius Scale by demonstrating a clinically interpretable five-component structure. The instrument may support the assessment of educational, organizational, and professional aspects of enteral nutrition practice among intensive care unit nurses. Full article

In Brazil, Community Restaurants (CRs) are regarded as an essential public initiative to expand food access for groups experiencing severe social vulnerability. This cross-sectional study analyzed the strategic effect of CRs as an indirect mechanism to ensure food availability in municipalities with more than 100,000 inhabitants, located in the North and Northeast regions of the country, using the CR evaluation matrix system of structural and process indicators as proxies to classify units as “not very effective,” “effective,” or “very effective,” rather than direct outcome impacts. Of the 94 CRs assessed (North: n = 23; Northeast: n = 71), most were rated as effective or very effective (95.6% in the North, 95.8% in the Northeast), with only one CR in Pará and three in the northeast (two in Bahia and one in Sergipe) classified as not very effective. The North region showed strong performance in financial resources, monitoring, location, physical structure, menu planning, incorporation of regional foods, volume of meals served to the attending public, and intersectoral actions. The Northeast excelled in financial resources, food security, physical structure, menu planning, and integration of regional foods, though it scored lower in education and volume of meals served to the attending public. This study represents the first structured application of the Oliveira matrix in the North and Northeast, providing new evidence on regional disparities and management challenges. These findings underscore CR’s strategic effectiveness in supporting regional efforts to improve food access and mitigate food and nutritional insecurity in historically vulnerable regions. However, outcome indicators such as dietary diversity, nutritional adequacy, and user health outcomes were not assessed. Future studies should incorporate these measures, alongside longitudinal designs and onsite evaluations, to better understand the broader impact of CRs on food and nutrition security. Full article

Background: Evidence on adolescents’ knowledge and practices related to healthy eating and food hygiene in Kazakhstan remains limited. This study aimed to assess knowledge and behaviors associated with healthy eating and food hygiene among adolescents in Karaganda, Central Kazakhstan. Methods: A cross-sectional study was conducted among 382 students aged 11–18 years from six schools. Data were collected using a bilingual questionnaire and analyzed using Chi-square tests and multivariable logistic regression. Results: Girls were significantly more likely than boys to demonstrate knowledge of healthy eating and food hygiene practices. According to parental reports, 61.5% of adolescents consumed fruit daily, whereas daily fast-food consumption was reported in 7.7% of boys and 7.5% of girls. Food-outsourcing company reports showed that complete meals and drinking water were available in all participating schools; however, dairy products were available in only half of the school cafeterias. Conclusions: The study identified sex- and age-related differences in adolescents’ knowledge and practices regarding healthy eating and food hygiene. The findings highlight the importance of combining nutrition education with improvements in the school food environment and greater parental involvement to promote healthier dietary behaviors among adolescents.

Background: Beijing’s 2024 school physical education reforms have substantially increased activity demands on children, yet population-level genotype data for Chinese schoolchildren remain scarce. Objectives: To characterize ACTN3 R577X, MTHFR C677T, MTHFR A1298C, and MTRR A66G polymorphisms in 564 Beijing schoolchildren; test Hardy-Weinberg equilibrium (HWE); compare allele frequencies with East Asian reference populations; and perform multi-locus cumulative allele analysis across all four loci. Methods: Cross-sectional study of 564 primary and secondary school students (265 males, 299 females) in Beijing. Genotyping was performed by PCR and Sanger sequencing using saliva-derived DNA; the overall call rate was 100% (564/564). HWE was assessed using the exact test of Wigginton et al. Allele frequencies were compared with 1000 Genomes CHB ($n=103$) and gnomAD EAS ($n\approx 2604$) using chi-squared or Fisher’s exact tests. Cumulative variant allele counts (0–8) were computed across all four loci. Linkage disequilibrium (LD) and haplotype frequencies were estimated using the EM algorithm. Results: All four loci were in HWE (all $p>0.05$). Genotype frequencies were: ACTN3 R577X—RR 31.56%, RX 49.11%, XX 19.33%; MTHFR C677T—CC 18.62%, CT 46.99%, TT 34.40%; MTHFR A1298C—AA 71.81%, AC 26.42%, CC 1.77%; MTRR A66G—AA 56.21%, AG 35.82%, GG 7.98%. No significant sex differences were observed at any locus (all $p>0.05$). Allele frequencies were consistent with East Asian reference populations. Across all four loci, 87.23% of students carried ≥2 variant alleles; 29.26% carried ≥4. LD between MTHFR C677T and A1298C was moderate to strong ($\left|D^{\prime }\right|=0.97$, $r^2=0.23$). The double-mutant T-C haplotype was rare (frequency $=0.002$). Conclusions: This study provides genotype frequency data for exercise- and folate metabolism-related polymorphisms in a sample of Beijing schoolchildren. These descriptive frequency data establish a baseline for future genotype–phenotype association studies; however, the sample is limited to two schools in two districts of Beijing and does not represent the broader Chinese pediatric population. Studies incorporating fitness, biochemical, and dietary data are required before such genetic profiles can inform educational or clinical recommendations. Given the purely descriptive, cross-sectional nature of the study and the absence of phenotypic data, these genotype frequency data do not, on their own, provide a basis for individualized physical education programming or nutritional recommendations.

Background/Objectives: Dance is a unique and physically demanding athletic art form that necessitates optimal nutritional intake for performance and long-term health. Nutrition knowledge (NK) is an essential factor that drives dietary behaviours and attitudes of athletes and performers, including dancers. Despite its importance, there appears to be limited research investigating the NK of dancers. This scoping review therefore aims to systematically explore the currently published literature on the NK of dancers globally, to understand the current levels of nutrition knowledge and gaps in knowledge as well as related dietary behaviours and inform future research and resource development for this population. Methods: Four electronic databases (MEDLINE, CINAHL, PubMed, and Web of Science) were searched in June 2026 for articles. Eligibility criteria included: Original research published in peer-reviewed journals between 2000–2025. Only English language studies reporting on the NK (general, sports, specific) of dancers were included. Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) was followed. Results: Of the 58 studies initially identified, a total of nine studies were included. All were quantitative and either cross-sectional (n = 5) or intervention (n = 4) studies. Data was collated from six countries with a total of 942 participants, and NK was directly assessed in all of the reviewed papers. The methodological quality and bias were assessed using the “Academy of Nutrition and Dietetics Quality Criteria Checklist for Primary Research” tool. Study designs and tools used to assess NK were heterogenous. Overall, dancers demonstrated low-to-moderate NK, with gaps in knowledge surrounding macronutrient composition of foods, and exhibited restrictive dietary patterns and body image concerns. Reliance on non-expert information sources was prevalent. Interventions designed to improve NK and related dietary behaviours showed positive impacts. Conclusions: Dancers’ NK is low-to-moderate, with suboptimal dietary behaviours, often driven by aesthetic pressures and a reliance on informal nutrition advice. Given the success of interventions to improve NK, future research should focus on targeted nutrition education strategies, focused on identified NK gaps for optimising dancers’ health, performance, and long-term well-being.

Background/Objectives: Surgical treatment of colorectal cancer (CRC) is associated with a substantial risk of postoperative complications and delayed recovery of functional capacity, particularly in older patients and those with multiple comorbidities. Preoperative prehabilitation has emerged as a strategy aimed at optimizing patients’ physical, nutritional, and psychological status prior to surgery; however, its clinical effectiveness and feasibility of implementation remain subjects of ongoing debate. The aim of this narrative review was to provide a clinically oriented synthesis of current evidence regarding multimodal prehabilitation in patients undergoing CRC surgery, with particular emphasis on perioperative outcomes, functional recovery, nutritional optimization, and implementation-related considerations. Methods: A targeted narrative review of the peer-reviewed literature indexed in PubMed (2015–2025) was conducted to identify contemporary review-type publications, including narrative reviews, systematic reviews, scoping reviews, and meta-analyses, addressing prehabilitation in CRC surgery. The findings were synthesized narratively and interpreted with emphasis on clinical applicability and translational relevance. Results: Twenty contemporary review publications were included in the analysis. Across the included publications, the most frequently reported favorable effects were observed for multimodal prehabilitation, incorporating physical exercise, nutritional support, and a psychological component. These interventions were associated with improvements in functional capacity and, in some meta-analyses, with a reduction in postoperative complication rates and shorter length of hospital stay, particularly in high-risk patients. Prehabilitation was assessed as safe and well tolerated. Conclusions: The current body of evidence indicates that multimodal prehabilitation may constitute a beneficial adjunct, particularly in improving functional capacity, while its impact on hard postoperative outcomes remains closely dependent on intervention quality, appropriate patient selection, and seamless integration with established perioperative care pathways. Future meta-analyses should address underexplored components of prehabilitation, including preparation for stoma formation and targeted educational and psychological support related to sexual health.

Background: Adolescents in low- and middle-income countries face a disproportionate burden of dietary inadequacy, yet evidence on the determinants of overall diet quality remains scarce. This study assessed the prevalence of macro- and micronutrient inadequate intake and identified factors associated with dietary adequacy among adolescents in rural Pakistan. Methods: A cross-sectional survey was conducted among adolescents using multistage cluster sampling. Dietary intake was assessed through a single 24-h dietary recall; nutrient adequacy was determined using age-and sex-specific Dietary Reference Intake (DRI) standards, including Estimated Average Requirements (EARs), Adequate Intakes (AIs), Estimated Energy Requirements (EERs), and Acceptable Macronutrient Distribution Ranges (AMDRs), as appropriate. Overall dietary adequacy was quantified using the Mean Adequacy Ratio (MAR), calculated as the unweighted mean of nutrient adequacy ratios for fourteen nutrients, including protein, fiber, calcium, iron, zinc, thiamin, riboflavin, niacin, vitamins A, B6, C, D, E, and folate, scaled from 0 to 100. Multivariable linear regression incorporating survey weights and clustering was used to identify independent predictors of MAR using STATA. Results: A total of 1132 adolescents were included. Most of the energy was derived from carbohydrates, and a high proportion of adolescents had energy intakes below age- and sex-specific Estimated Energy Requirement (EER) values, while very high levels of inadequacies were observed for protein, fiber, calcium, vitamin D, and vitamin A. The mean MAR score was 54.04 ± 16.51, indicating overall poor dietary adequacy. In multivariable analysis, male sex (β = 3.26; 95% CI: 1.76, 4.75), belonging to the richest wealth quintile (β = 5.81; 95% CI: 1.76, 9.86), always eating between meals (β = 6.70; 95% CI: 3.93, 9.47), and use of bar soap for handwashing (β = 4.97; 95% CI: 2.00, 7.94) were significantly associated with higher dietary adequacy. Adolescents who were underweight (β = −2.40; 95% CI: −4.81, −0.11) and those with moderate physical activity levels (β = −3.96; 95% CI: −7.62, −0.29) had significantly lower dietary adequacy scores. Conclusions: Dietary inadequacy among rural adolescents in Pakistan was highly prevalent and was associated with socioeconomic, behavioral, and nutritional factors. These findings highlight the need for interventions that address food insecurity, promote equitable food distribution, and strengthen nutrition education to support adolescent health and nutrition. However, these findings should be interpreted in light of the cross-sectional design and the use of a single 24-h dietary recall, which may not reflect habitual dietary intake. Full article

Background. A substantial body of scientific evidence indicates a close association between dietary habits, body composition, and athletic performance. Nevertheless, dietary inadequacies remain prevalent among athletes, including adolescents. The present study aimed to assess the body composition and dietary habits of participants in the Junior National Swimming Championships. Methods. The study included 39 female competitors (17.8 ± 0.2 years) and 88 male competitors (17.7 ± 0.4 years), all of whom provided informed consent to participate. Dietary habits were evaluated using a questionnaire developed in accordance with the principles of the Swiss Food Pyramid. Additionally, participants provided information regarding their training workload, including the number of weekly training sessions and the total distance swum during training. Body composition was assessed using bioelectrical impedance analysis (Tanita BC-418 MA). Results. Male swimmers exhibited significantly different values across all body composition variables compared with female swimmers (p < 0.05), whereas no significant differences were observed in training workload between the groups. Regardless of sex, the majority of participants reported consuming at least three meals per day, as well as the recommended amounts of dairy products and fruit. In contrast, fish consumption was below the recommended level. Female swimmers consumed sweet snacks and fast food significantly less frequently than their male counterparts (p < 0.05), whereas male swimmers reported a higher frequency of pork product and sugar-sweetened carbonated beverage consumption (p < 0.05). Conclusions. Young competitive swimmers exhibit several nutritional inadequacies. Although their consumption of fruit and vegetables generally aligns with current dietary recommendations, fish intake remains insufficient. Female swimmers demonstrated more favourable dietary patterns than male swimmers. Accordingly, ongoing nutrition education should constitute an integral component of the athletic training process.

Food insecurity is a major public health concern among university students. This cross-sectional study examined factors associated with food insecurity during and after the COVID-19 pandemic among 1864 students (mean age: 20.6 ± 2.9 years) from selected public universities in Northwest Mexico. Data were collected in two cross-sectional survey waves: during the COVID-19 pandemic (n = 1188) and after the pandemic (n = 676). Data were collected through online surveys during the pandemic and face-to-face interviews in the post-pandemic period. Food insecurity was assessed using the Food Insecurity Experience Scale (FIES). Multiple linear regression models were used to identify factors associated with food insecurity and to examine its association with body mass index, perceived stress, sleep quality, and academic performance. Overall, 62.2% of students experienced food insecurity. Food insecurity was higher among students surveyed after the COVID-19 pandemic than among those surveyed during the pandemic (73.7% vs. 55.7%, p < 0.001). During the pandemic, higher food insecurity scores were associated with older age, female sex, indigenous self-identification, living alone, academic discipline, study hours, educational financing, and poorer nutritional behaviors. In the post-pandemic period, indigenous self-identification, living arrangements, academic discipline, and poor nutritional behaviors remained associated with food insecurity. In both periods, food insecurity was associated with higher perceived stress, poorer sleep quality, and lower academic performance (p < 0.05). These findings suggest that food insecurity remains a major concern among university students and indicate the importance of developing culturally appropriate strategies to support vulnerable student populations.

Background: Nutrition knowledge (NK) may influence dietary behaviours and athlete health; however, limited research has examined the relationship between NK and risk of low energy availability (LEA) in female team sport athletes. Objective: This study aimed to assess NK and LEA risk in female Ladies Gaelic Football (LGF) players and to examine the relationship between these variables. Results: Female LGF players (n = 58) aged 18–35 years completed a 75-item online questionnaire comprising the Abridged Nutrition for Sport Knowledge Questionnaire (ANSKQ) and the Low Energy Availability in Females Questionnaire (LEAF-Q). Mean total ANSKQ score was 53.1 ± 7.6%, categorized as “average”, while the mean sport nutrition knowledge (SNK) score was 48.2 ± 8.5%, categorized as “poor”. Lower micronutrient knowledge scores were observed among younger players and those with lower educational attainment (p < 0.05), while players with prior nutrition education demonstrated greater supplement-related knowledge (p < 0.05). Overall, 56.9% of the participants were classified as being at risk of LEA according to LEAF-Q criteria. LEA risk differed according to playing level and nutrition education status (p < 0.05); however, no association between overall NK and LEA risk was identified. Players identified as being at risk of LEA also demonstrated greater menstrual dysfunction and injury-related absence. Conclusions: These findings indicate a high prevalence of LEA risk and suboptimal sport NK among female LGF players and suggest that NK alone may be insufficient to protect against LEA risk in female team sport athletes. Ongoing screening, nutrition education, and broader athlete support strategies are therefore warranted in this population. Full article

On behalf of the Canadian Association of Psychosocial Oncology, we are pleased to present the abstracts from the 2026 Annual Conference, titled “A New Horizon: Expanding the Access and Impact of Psychosocial Oncology”. The 41st Annual CAPO Conference was held in St. John’s, Newfoundland from 8 June 2026 to 9 June 2026. As we stand at a new horizon in psychosocial oncology, we recognize the unprecedented opportunities to expand both the access to and the impact of comprehensive cancer care. This conference will explore innovative strategies for breaking down traditional barriers that have historically limited access to psychosocial support, including geographic isolation, resource constraints, cultural disparities, and systemic inequities in healthcare delivery. This expansion of reach and influence represents not merely growth in service numbers, but a fundamental transformation in how we conceptualize, design, and implement patient-centered psychosocial care across diverse communities and care settings. We will explore scalable solutions that amplify impact while maintaining the deeply personal, human-centered approach that defines excellence in psychosocial oncology. From telehealth innovations and peer support networks to community-based interventions and integrated care models, this conference will showcase evidence-based strategies that expand our collective ability to support individuals and families navigating the cancer journey, wherever they may be. This conference brought together key stakeholders including multidisciplinary professionals from nursing, psychology, psychiatry, social work, spiritual care, nutrition, medicine, rehabilitation medicine, occupational health and radiation therapy for both adult and pediatric populations. Participants included clinicians, researchers, educators in cancer care, community-based organizations and patient representatives. Patients, caregivers and family members presented abstracts that speak to their role in managing cancer experiences and care. Over one-hundred and fifty (150) abstracts were submitted for presentation as symposia, 20 min oral presentations, 10 min oral presentations, 90 min workshops and poster presentations. We congratulate all the presenters on their research work and contributions. Full article

More frequent consumption of home-cooked meals is associated with better diet quality, and food literacy questionnaires may be able to identify factors that influence cooking frequency. Eating and Food Literacy Behaviors Questionnaire (EFLBQ) factor scores and demographic characteristics were examined as predictors of home cooking in a group of women aged 18 to 30 years. Participants were recruited by a third-party provider. EFLBQ factor scores (F1: health and nutrition, F2: taste, F3: food preparation, F4: planning and decision making, and F5: convenience), demographic characteristics, and frequency of cooking were measured. Groups were compared using ANOVA and Games–Howell post hoc tests. Pearson’s r or point-biserial tests were used to examine relationships between variables. Significant predictors were entered into a structural equation model (SEM) to predict home cooking frequency. A total of 107 Asian, 113 Black, 108 Hispanic, and 111 White women participated. The F1 factor score (health and nutrition) was a positive mediator between age and cooking frequency, and the F5 score (convenience) was independently and negatively correlated with how often the women cooked. Nutrition educators should address these EFLBQ factor topics in interventions and use these factor scores to measure changes in participants’ behaviors after they participate in educational programs that promote cooking.

Background: This study explored the observations and experiences of athletic trainers (ATs) regarding food security constraints and drivers among collegiate student-athletes through the framework of the social determinants of health (SDOH). Methods: Seventeen ATs from nine public Mountain West Division I schools participated in one of six 90 min, virtual focus groups conducted in July–December 2023. A phenomenological design and constructivist theoretical framework were employed to analyze transcripts, compile themes, infer food security constraints and drivers, and map them to SDOH domains. Results: Emerging constraints and drivers mapped to seven of the eight SDOH domains (education, employment, health systems and services, housing, income and wealth, physical environment, and social environment); no themes related to the public safety domain. Conclusions: ATs identified a considerable number of food security constraints and drivers; however, based on the findings of other studies, their observations were not comprehensive. Incorporating the findings of those other studies, food security constraints and drivers exist across all eight SDOH domains. Four concepts spanned multiple domains: student-athlete normative expectations, nutrition/food security prioritization, financial disparities, and residing off campus. To ensure food security among collegiate student-athletes, AT perceptions suggest that structural changes facilitating the implementation of necessary food drivers may be warranted. Full article
