The aim is to examine the relationship between factors thought to potentially influence weight gain, such as sustainable nutrition (SN) behavior and plate clearing tendency (PCT) during pregnancy, and gestational weight gain (GWG). This cross-sectional correlational study was conducted on 340 women in the last trimester of pregnancy. Study data were collected through face-to-face interviews using a questionnaire form between October-December 2024. PCT is lower among younger women, those with low income and those with insufficient GWG (p<0.05). SN behaviors are higher in those who are older, have higher education levels, lower income and moderate physical activity (p<0.05). A negative correlation was found between food preference, a component of SN behaviors, and GWG (p<0.05). In the binary logistic regression model, higher pre-pregnancy BMI significantly increased the likelihood of excessive GWG (OR=1.49, 95% CI:1.332–1.665, p<0.001), whereas high physical activity was found to be protective against excessive GWG (OR=0.214, 95% CI:0.061–0.747, p=0.016). It was determined that pre-pregnancy BMI was higher and physical activity was lower in those with excessive GWG, in addition, food preference, one of the factors of SN behavior, affected weight gain. Food preference can be considered as a factor that may affect GWG.

Malnourished infants u6m are a vulnerable but not enough-prioritized group, with low consolidated evidence to guide outpatient and community-based care. This study synthesized evidence on outpatient and community-based management of malnourished infants u6m, focusing on intervention strategies, outcomes, barriers, and policy implications. Following the JBI framework and PRISMA guidelines, this review included information about the outpatient or community-based management of malnourished infants u6m or mother–infant dyads, published in English between 2007 and 2025. Four databases and multiple institutional websites were searched, supplemented by grey literature. Data were extracted on various study features, interventions, and outcomes. Total 26 studies were included, only five published after the new 2023 WHO guideline. Evidence was concentrated in sub-Saharan Africa and South Asia. Several included studies described outpatient care as feasible and acceptable in multiple contexts, with reported recovery rates ranging from 65% to 91%; however, methodological heterogeneity limits comparability across studies. Breastfeeding support, maternal health, and culturally adapted interventions were described as important indicators. Tools such as MAMI clinical care pathway, MUAC and the MAMI WAZ look-up chart were described as effective but require further validation and contextual testing. Major barriers mentioned shortages of trained staff, inconsistent protocols, and policy reluctance to scale outpatient models. Outpatient and community-based care for malnourished infants u6m aligns with recent WHO guidance on managing ‘at-risk’ infants. However, widespread adoption requires stronger evidence-based management or tools, integration into health systems, and national policies. Strengthening research and programmatic consensus will be essential to improve outcomes for this vulnerable population.

Military veterans (ex-serving members of the Armed Services) experience unique physical and mental health challenges, with diet playing a critical role in chronic disease management and well-being. This review aimed to evaluate veterans’ dietary intake against nutrient reference values (NRV) relevant to age and sex. A systematic search of CINAHL, MedLine, Scopus, PubMed and AMED (January 2024, updated March 2025) identified 1268 records; thirty-three studies (n 654 323) met inclusion criteria. Eligible designs included cross-sectional, cohort, quasi-experimental and randomised controlled trials. Data were extracted using the Joanna Briggs critical appraisal checklist, indicating low risk of bias. Across studies, veterans’ intake of fibre, folate, vitamin D, Ca, potassium, fruits, vegetables, wholegrains and legumes was consistently inadequate, with overall diet quality rated poor to average. BMI ranged widely, and veterans reported high rates of mood disorders and low quality-of-life scores. These findings highlight key nutrients and dietary patterns that might be considered and targeted in dietary and lifestyle interventions for promoting the physical and mental health of veterans.

In 250 men (21.4 ± 2.9 years; BMI 24.2 ± 3.0 kg∙m-2) commencing arduous military training during winter, we investigated the effect of 12 weeks vitamin D supplementation on lower body (pelvic girdle, sacrum, coccyx, and lower limb) overuse musculoskeletal injury risk in a randomised, placebo-controlled trial. Participants received either simulated sunlight (1.3× standard erythemal dose in T-shirt and shorts, three times per week for 4 weeks and then once per week for 8 weeks), oral vitamin D3 (1000 IU∙d-1 for 4 weeks and then 400 IU∙d-1 for 8 weeks), or placebo for each intervention. Serum vitamin D metabolites and bone metabolism biomarkers were measured at baseline, week 5, and 12. At baseline, 29% of participants were vitamin D sufficient (25-hydroxyvitamin D ≥50 nmol∙L-1). Vitamin D supplementation achieved vitamin D sufficiency in 95% of participants after 4 weeks. During 6 months of training and subsequent 3 years of military service, 100 lower body overuse musculoskeletal injuries were diagnosed by clinicians. Frailty models indicated no difference in injury risk between vitamin D and placebo during military training (HRplacebo:vitamin D = 1.23 [95% CI: 0.57–2.66], P = 0.597) or military service (HRplacebo:vitamin D = 0.94 [95% CI: 0.60–1.46], P = 0.782). Both safe simulated sunlight and oral vitamin D3 were effective in achieving and maintaining vitamin D sufficiency in almost all. There was no clear evidence for vitamin D to affect the risk of lower body overuse musculoskeletal injury during 6 months of military training or subsequent 3 years of military service.

Children with CHD have demonstrated a rise in obesity, and have unique risks related to comorbidities of obesity, including feeding dysfunction and exercise limitations. The incidence and cause of obesity among patients with surgically corrected CHD are not fully understood. This single-centre, longitudinal, retrospective cohort study identified patients between 2004 and 2020 with surgical correction. Diagnoses were restricted to d-transposition of the great arteries, coarctation of the aorta, or tetralogy of Fallot with surgical repair by 6 months of life without long-term post-operative complications or chromosomal abnormalities. Evaluation of Body Mass Index by survival curve for endpoints of overweight and obesity, as well as descriptive analysis of the population, was performed compared to the expected prevalence in the state of Oregon (13.7%). Cohorts were divided into eras in 5-year increments. Of 240 patients identified, 87 (36.2%) were overweight and 50 (20.8%) obese, findings significantly higher than expected prevalence (p = <0.01) for the same time period in the state of Oregon. Patients with coarctation of the aorta had a higher prevalence than other diagnoses (p = <0.01). Patients in the 2004–2008 cohort had the highest rates of obesity compared to other cohorts (p = <0.01 and p = <0.01, respectively), likely due to a longer observational period. However, the 2014–17 cohort had the highest rate of increase in hazard ratio. Children with surgically corrected CHD demonstrate higher prevalences of obesity compared to the general population. There is variation by diagnosis, with coarctation of the aorta having comparatively higher prevalences of obesity. Several factors may impact this discrepancy, including sports participation restrictions and initial emphasis on weight gain.

Individuals with type 2 diabetes are at increased risk for developing CVD. We assessed how dietary counselling on a high-quality, fibre-rich diet influenced cardiometabolic health of patients with type 2 diabetes. In this 6-month trial, 121 patients with type 2 diabetes (67 (sd 8·7) years, 68 % men, BMI 27·8 kg/m2) were assigned to dietary counselling (n 61) or standard care (n 60). Counselling included 4–7 individual sessions with a dietitian, aimed at increasing fibre intake to improve diet quality. The primary outcome was a composite risk score estimating 10-year CVD risk. Secondary outcomes included diet quality, assessed by the Dutch Healthy Eating Index-2015 (DHD15-index), HbA1c, LDL-cholesterol, blood pressure, body weight and medication use. Diet quality score at baseline was 115 (sd 26) and similar across groups. Over 6 months, DHD15-index scores improved by 4·5 points (95 % CI: −0·2, 9·1) in the intervention group v. control, but not significant. The change in 10-year CVD risk across the 6 months of the trial (primary outcome) did not differ between groups −0·1 %, 95 % CI: −0·2, 0·1. Changes over time in HbA1c (–1·1 mmol/mol, 95 % CI: −4·4, 2·3), LDL-cholesterol (0·0 mmol/l, 95 % CI: −0·2, 0·3), blood pressure (–1 mmHg, 95 % CI: −6, 4), body weight (–0·1 kg, 95 % CI: −1·2, 1·1) or medication use did not differ between groups. Dietary counselling for 6 months slightly improved adherence to a high-quality, fibre-rich diet in patients with type 2 diabetes but did not significantly impact cardiometabolic health or medication use.

Autism spectrum disorder (ASD) is a population-scale condition with life-course health consequences, yet nutrition support remains inconsistently embedded in routine pathways. Food selectivity is common in ASD and is associated with restricted dietary variety, nutritional imbalance, gastrointestinal morbidity and cardiometabolic vulnerability. Current responses are predominantly clinic-and family-centred and are difficult to scale equitably. This commentary argues that institutional food services (schools, day-care and residential settings) are an underused public health platform to improve inclusion and accountability through sensory-accessible, nutritionally adequate meals. Because these services are commissioned, standardised and audited, sensory accessibility can be operationalised via procurement specifications and quality indicators, enabling benchmarking across sites. Evidence from sensory-informed menu adaptation and implementation work suggests feasibility within routine operations and supports evaluation using system-relevant outcomes (acceptability, nutritional adequacy, waste, feasibility and maintenance). Three policy actions are proposed: embed sensory accessibility in institutional standards, integrate nutrition across sectors and fund scale-up using implementation science.

Diet plays a critical role in development and progression of Crohn’s disease (CD). Dietary indices are important tools to evaluate diet quality and inflammatory potential, and we investigated their associations with pediatric CD in comparison to healthy children. A cross-sectional study including 144 children with CD (122 with clinically active and 22 with quiescent disease) and 57 healthy controls 6-18 years of age was conducted. Dietary intake was estimated using three 24-h dietary recalls. Diet quality was assessed using the Healthy Eating Index (HEI)-2015, alternate Mediterranean diet (aMed) score and dietary inflammatory potential using the modified Children-Dietary Inflammatory Index (mC-DII). Children with active CD had lower total HEI-2015 and aMed scores than healthy controls. A similar pro-inflammatory mC-DII score was found across the three groups. A higher mC-DII score in patients with CD was associated with higher intake of refined sugars, saturated fats and proteins, and lower intake of whole grains and dairy, highlighting dietary components contributing to pro-inflammatory potential. Similarly, healthy children in the highest mC-DII tertile consumed more added sugars and sodium and fewer whole grains, fruits, vegetables, and plant proteins. Fiber intake was significantly lower in children with active CD (median fiber %DRI: 37.0 IQR [22.6-48.3] vs 41.2 IQR [34.1-49.1] vs 45.8 IQR [35.7-62.0], P <0.001). Using three dietary indices to evaluate diet quality and dietary inflammatory potential, both children with CD and healthy children in this cohort consume a poor-quality, pro-inflammatory diet low in fiber, but the quality and fiber content are significantly lower in children with active CD. Future randomized controlled trials are required to evaluate the effect of dietary modification on the risk and progression of pediatric CD.

The effect of dietary intake on body weight may vary based on individual genetic differences. However, children are rarely used in such investigations. The aim was to identify possible genetic moderation through polygenic scores (PGS) for BMI, of the association between dietary intakes and BMI in children. The study sample included children who were part of a French-Canadian birth-cohort study. BMI data was available on seven occasions between ages 4 and 13 years. FFQ (juice and fruit drinks, sweets and snack foods, meats, and fruits and vegetables) and 24-h dietary recall (proteins, lipids, carbohydrates, total energy) data were available up to 4 years. Linear mixed models were used to account for repeated BMI measurements. The consumption of juice and fruit drinks (in girls), sweets and snack foods, fruits and vegetables, proteins, lipids, carbohydrates and total energy were associated with BMI. Associations with BMI increased with age (kg/m2 per year) for fruits and vegetables (β: −0.03, 95%CI: −0.06;−0.01), lipids (β: 0.11, 95%CI: 0.01;0.22), carbohydrates (β: 0.05, 95%CI: 0.01;0.08), and total energy (β: 0.07, 95%CI: 0.02;0.12), and with higher values of a PGS (kg/m2 per SD) for proteins (β: 0.54, 95%CI: 0.03;1.06), lipids (β: 0.63, 95%CI: 0.12;1.13), and total energy (β: 0.32, 95%CI: 0.06;0.58). Using longitudinal data, we showed that the associations between specific dietary intakes and BMI may vary depending on age and genetic susceptibility in childhood.

This review paper provides an overview of the Scientific Advisory Committee on Nutrition’s (SACN’s) report ‘Feeding young children aged 1 to 5 years’. The purpose of the report was to (1) review the scientific basis of current recommendations for feeding children aged 1 to 5 years, (2) consider evidence on developmental stages and other factors that influence eating behaviour and diversification of the diet in the early years and (3) make recommendations for policy, practice and research. This report was based on a comprehensive assessment of the systematic review (SR) literature and also evidence provided by the Diet and Nutrition Survey of Infants and Young Children and the National Diet Nutrition Survey. Dietary survey data indicated that the diets of children aged 1 to 5 years in the UK did not meet current dietary recommendations for several nutrients. Intakes of energy, free sugars and protein exceeded recommendations, while dietary fibre intakes were below the recommended level for this age group. Children from lower socio-economic status households or from certain ethnic groups may be at risk of inadequate intakes of Fe, Zn, vitamin A and vitamin D. SR evidence indicated that in children aged 1 to 5 years, higher free sugars intake is associated with increased dental caries, higher consumption of sugar-sweetened beverages is associated with increased risk of overweight/obesity and higher child BMI is associated with higher risk of adult overweight/obesity. Based on the evidence, SACN has made recommendations to improve the diets of young children in the UK.

The blue gum chalcid (Leptocybe invasa) is a serious invasive, galling insect pest of eucalypts grown outside Australia. Variability in resistance of species and genotypes of Eucalyptus to the pest is widely reported but without consideration of the influence of silviculture on the severity of galling. We assessed the variability of gall expression by 29 genotypes of E. camaldulensis by L. invasa in common nursery experiments and in 5 common garden arboreta planted in diverse climatic zones and soil types around Kenya. We quantified variation in growth and the concentrations of defensive chemical compounds (namely polyphenolic compounds) to assess possible genotype × environment interactions which we also relate to the climate of the parent seed trees in Australia. Generally, genotypes endemic to low latitude regions of Australia were more resistant to the pest while the concentration of quinic acid derivatives (QUIN) exhibited an interaction with arboretum location in Kenya. The concentration of QUIN in potted plants did not vary significantly with nitrogen supplementation. However, growth rates and total polyphenolic concentrations varied with arboretum location. Since QUIN, which have been previously shown to confer resistance against L. invasa, did not vary in different arboreta, resistant subspecies and genotypes of E. camaldulensis can be deployed in novel habitats and will not be galled. Our findings support the critical need to plant stock of known genotype(s) rather than planting stock grown from locally collected seed. This will require the establishment of eucalypt seed orchards if clonal production of planting stock is not possible.

Despite increasing efforts to promote and support breastfeeding, the United States continues to have some of the lowest exclusive and sustained breastfeeding rates globally. Foreign-born immigrants and refugees specifically have been reported to have high initiation but low exclusive breastfeeding (EBF) rates. This scoping review aims to explore what is known about strategies to support breastfeeding among foreign-born mothers in the United States using the Arksey & O’Malley framework for scoping reviews and PRISMA-ScR (Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews). Six databases were searched using a comprehensive search strategy and 2103 articles were identified, of which 31 met eligibility criteria and discussed 33 specific breastfeeding interventions. The articles describe a range of interventions, including breastfeeding promotion and education (n = 30), hands-on breastfeeding support (n = 9), material support like giving breastfeeding supplies and food (n = 16), social support (n = 18) and social marketing campaigns (n = 1) to promote community support for breastfeeding. Common strategies for implementing these interventions include individual counselling (n = 21), group breastfeeding education (n = 17), informational materials (n = 12) and family support promotion (n = 11). In total, 87·3% of the immigrant mothers targeted by these breastfeeding support interventions were Hispanic, and 4·5% and 7·0% were mothers of African and Asian descent, respectively. This study reveals limited data and key gaps in efforts to preserve the culture of breastfeeding and promote EBF among multicultural immigrant and refugee families, particularly non-Hispanic groups. Addressing these gaps will improve optimal infant feeding practices among foreign-born mothers in the United States and, consequently, maternal and infant health outcomes.

This study investigated changes in serum folate and B12, and associations with endurance performance and bone outcomes, in women during military training. Women (n 137) had serum folate and B12, haematological markers and endurance performance (2·4 km run) measured at the start (week 1) and end (week 13) of British Army basic training. Whole-body areal bone mineral density and markers of bone metabolism were measured at week 1. Training decreased serum folate (mean change (95 % CI), −2·3 (−3·0, −1·6) nmol ∙ l−1, P < 0·001), B12 (−16 (−32, 0) pmol ∙ l−1, P = 0·042), Hb (−0·7 (−0·9, −0·5) g ∙ dl−1, P < 0·001) and erythrocyte count (−0·2 (−0·3, −0·2) × 10^9 ∙ l−1, P < 0·001), but had no effect on mean corpuscular volume (P = 0·438) or erythrocyte distribution width (P = 0·088). There was no association between serum folate, serum B12, Hb or erythrocyte count with run time (P ≥ 0·518). Serum B12 was not associated with areal bone mineral density or bone metabolism at week 1 (P ≥ 0·152). Higher serum folate was associated with lower plasma c-telopeptide cross-links of type I collagen (standardised β (95 % CI) = −0·31 (−0·48, −0·15), P < 0·001), but not whole-body bone mineral density or plasma procollagen type I N-terminal propeptide (P ≥ 0·152). Serum folate and B12 decreased after military training in women, resulting in a high prevalence of folate deficiencies at the end of training. Low serum folate may contribute to increased bone resorption, the implications of which are unclear.
