BackgroundThe introduction of mandatory calorie labelling among large food businesses (chains) in England in 2022 has been found to have little impact on consumer behaviour, but overall calories on restaurant menus have decreased slightly. This study examined menu changes post policy implementation, and the population groups likely to have been affected most. MethodsMenu data from 169 chains in Great Britain were extracted from two online food delivery platforms in June 2022 and June 2023. We selected 10 categories (specific foods or chains) jointly with public and policy advisors. Menu changes over time were assessed with multilevel models accounting for whether an item was continuously on the menu and for the type of chain. Where changes were found, we assessed differences in purchasing frequency by consumer characteristics using 2022 OOH purchase data (Worldpanel by Numerator, GB OOH Panel). ResultsChanges were observed in two (out of 10) categories examined and were driven by changing items on the menu rather than reformulating continuous dishes. Chains that used a healthy tag on the delivery website increased the share of mains under 600 kcal by 3.7 percentage points (95% CI 0.2 to 7.2), while average calories did not change (-17.6 kcal/item, 95% CI -38.7 to 3.4). Men, people aged 35-44 years and with high SES were found to purchase more frequently from these chains. Across all chains, the share of lower-calorie coffees decreased by 10 pp (95% CI -18.0 to - 0.02), with purchasing more frequent among men and increasing with age. ConclusionsAlthough data were available for one year only post-policy implementation, menu changes among the investigated foods and chains were limited. While menu change may equitably improve population dietary health, dietary inequalities may exacerbate if only healthy chains already offering lower-calorie food change their menus.

Introduction: Minimum dietary diversity (MDD) is a key indicator of complementary feeding among children aged 6-23 months. This study examines the prevalence, trends, and determinants of MDD in Bangladesh over the period 2014 - 2022. Design: Secondary analysis of the Bangladesh Demographic and Health Survey (BDHS) data between 2014 and 2022. The primary outcome was MDD defined as consumption of at least 5 of 8 food groups (MDD-8). We included 6,080 children aged 6-23 months to assess trends over time. The pooled datasets were used to identify factors associated with MDD-8. Multiple logistic regression was performed to assess the association between different factors and MDD-8, accounting for the complex survey design. Setting: Bangladesh Results: The proportion of children achieving MDD-8 increased from 26.4% in 2014 to 38.7% in 2017, but plateaued at 37.1% in 2022, with an average annual increase of 4.3% between 2014 and 2022. MDD-8 improved with child age. Higher odds of achieving MDD-8 were observed among children surveyed in later years, from wealthier households, with mothers who had >=4 ANC visits, received PNC, had higher education, were employed, and had media exposure. Older age and higher birth order were also associated with achieving adequate MDD. Children in Chattogram and Sylhet were less likely to meet MDD-8 compared to Dhaka. Conclusions: While dietary diversity improved between 2014 and 2017, progress stalled thereafter. Targeted, multisectoral strategies focusing on womens empowerment, health service utilisation, media engagement, and disadvantaged regions are needed to improve child dietary diversity in Bangladesh.

BackgroundPacked lunches are a common feature of early childhood food provision, yet evidence describing their nutritional composition in early years settings remains limited. Understanding the foods provided during this developmental period is important, given the potential influence of early dietary exposures on later health. AimTo characterise the composition, nutritional quality, cost, and dietary patterns of packed lunches brought from home in Early Childhood Education and Care settings, and to examine variation by child age and area-level deprivation. MethodsA cross-sectional analysis was conducted using a remote food photography method to assess packed lunches provided for children aged 1-4 years attending early years settings across Essex, UK. Food items were categorised into predefined groups, and nutrient composition was estimated. Area-level deprivation was determined using the English Index of Multiple Deprivation (2019). Non-parametric tests assessed between-group differences. Principal components analysis (PCA) was used to identify patterns of co-occurring foods. ResultsA total of 389 packed lunches were analysed. Starchy foods (82%), fruit (81%), dairy or alternatives (72%), and savoury snacks (74%) were commonly provided, while vegetables were less frequent and fish was rarely observed (1.5%). Overall, 97.7% of lunches contained at least one ultra-processed food (UPF), with a median of three UPF items per lunch and 74% of total energy derived from UPFs. Median energy provision was 400 kcal (IQR 309-518). Nutrient composition was broadly similar across deprivation groups, although cake and biscuit counts and UPF item counts were modestly higher in more deprived areas. The median estimated lunch cost was {pound}1.79 and did not differ by deprivation. ConclusionsPacked lunches in early years settings frequently contained ultra-processed foods and showed considerable variability in nutritional quality. Socioeconomic differences were limited, suggesting that contemporary packed lunch practices may reflect influences operating across population groups. Further research across diverse regions is warranted to better understand the provision of packed lunches and their implications for early dietary exposure.

PurposeAdequate hydration is vital for health, yet many people do not meet fluid recommendations. This study aimed to characterise the role of water and sugar-sweetened beverages in hydration across different levels of socioeconomic status (SES) in the UK. MethodsIn a pre-registered cross-sectional study, participants (N = 1,112) recalled beverages consumed on the previous day and reported urine colour as an indicator of their hydration status. We analysed water intake (H1), sugar-sweetened beverage (SSB) intake (H2), and SES (education; H3) as predictors of hydration status using stepwise binomial logistic regression adjusted for health, demographic, and lifestyle covariates. ResultsForty percent of participants were classified as underhydrated. Higher water intake was associated with a greater likelihood of adequate hydration: Drinking one extra glass of water per day (250 ml) increased the odds of being adequately hydrated by about 16%. However, SSB intake was not associated with hydration unless intake from other drink sources was held constant. Having a higher versus lower level of education was not significantly associated with hydration status, although finer-grained and income-based analyses suggested modest socioeconomic differences. ConclusionWater intake--rather than SSB intake--is the primary correlate of adequate hydration in this UK sample. Public health initiatives should emphasise the importance of water for hydration, invest in ways to make water more appealing, and promote the use of urine colour as a marker of hydration status.

BackgroundPaediatric liquid medicines (PLMs) routinely contain sucrose to improve palatability, yet their cariogenic potential is well established. Healthcare professionals awareness and prescribing practices regarding sugar-free PLMs have received limited study in India, particularly in Uttarakhand. MethodsA descriptive cross-sectional study was conducted among 500 healthcare professionals aged [&ge;]25 years, using a pilot-tested structured questionnaire (Cronbachs = 0.85), administered online and in person across Uttarakhand districts (January-March 2024). After excluding 69 incomplete responses, 431 participants were analysed (response rate: 86.2%), comprising general medicine practitioners (49%, n = 211), paediatricians (27%, n = 116), and dental practitioners (24%, n = 104). Descriptive statistics and chi-square tests were applied (p < 0.05). ResultsPrescription decisions were primarily driven by childs age and weight (58%), cost (40%), and pharmaceutical brand (37%). While 88% recognised PLM sweetness and 67% were aware of pH-dental harm links, only 20% associated PLMs with dental caries. Overall awareness of hidden sugars was 73%. Eighty-three percent knew of sugar-free alternatives (50% local availability), yet 80% found them less palatable and 85% costlier. Only 48% routinely provided oral health advice. A statistically significant association was found between specialty and sugar-free PLM awareness (p = 0.03), with dental practitioners recording the highest awareness (90%). ConclusionsHealthcare professionals demonstrated variable levels of knowledge, attitudes, and practices regarding PLMs, with critical gaps in caries recognition (20%) and oral health counselling (48%). Despite high sugar-free PLM awareness, uptake is constrained by perceived cost and palatability barriers. Targeted continuing medical education and policy measures, including sucrose-free labelling promotion, are needed to improve paediatric oral health outcomes in Uttarakhand. KEY MESSAGESO_LIOnly 20% of healthcare professionals in Uttarakhand associated pediatric liquid medicines (PLMs) with dental caries, representing a critical knowledge gap despite 88% recognising their sweetness.

BackgroundChildhood overweight is a major health concern with long-term consequences. Dutch guidelines recommend that general practitioners (GPs) screen for overweight in children regardless of visit reason, yet GPs infrequently initiate weight-related conversations. ObjectivesTo explore what determines GPs initiation of conversations about childhood overweight, identify the determinants with the highest potential for change, and examine how, in particular, emotional responses and equanimity, relate to GPs intention to initiate conversations. MethodsA cross-sectional survey was conducted among Dutch GPs (in training) between March-May 2025. Behavioural determinants, based on the Theoretical Domains Framework, emotional responses, equanimity, and anticipated behaviour and implementation success were assessed. For all determinants, room for improvement (deviation from maximum), relevance (correlation with anticipated behaviour), and the potential for change (combining these two) were calculated using R. Open-ended responses were analysed using content analysis. Results57 GPs completed the survey. Most reported adequate skills (66%), knowledge (61%), and motivation (74%); yet only 25% reported high implementation success. Their behaviour is constrained by a lack of habituation, negative outcome expectancies, failing to remember to act, and a lack of social and organizational support. Emotional responses were evident, with 10-15% of respondents reporting high arousal or clearly positive or negative valence. Valence, but not arousal or equanimity, was positively associated with anticipated intention (r = 0.45, p < 0.001). ConclusionSupporting routine weight-related conversations requires strategies to strengthen habit formation, reshape outcome expectancies, support memory, address social and organizational factors, and further explore GPs emotion regulation. Key messagesO_LIAlthough highly motivated, general practitioners infrequently initiate conversations about childhood overweight due to existing practical barriers and barriers related to internal processes. C_LIO_LIHabit formation showed the greatest potential for change, emphasizing the importance of automaticity in initiating conversations. C_LIO_LIRegulation of emotions and outcome expectancies, may support GPs in consistently initiating sensitive weight-related conversations. C_LI

Introduction. Ultra-processed foods (UPFs), defined as foods in group 4 of the NOVA classification system, are a key contributor to chronic disease in the United States. Front-of-package warning labels ('warnings') offer a promising strategy to help Americans reduce consumption of UPFs. Requiring warning labels on UPFs could help reduce consumption of these foods. However, the effects of UPF warnings are largely unknown. The impact of warning labels on UPFs among Latino adults was examined. Study design. Online randomized trial. Setting/participants. 4,107 Latino adults (49% limited English proficiency) in the US. Intervention. Participants viewed one of three labels: control labels displaying barcodes; identity warnings stating 'WARNING: Ultra-processed food'; or health warnings stating 'WARNING: Consuming ultra-processed food and drinks can cause weight gain, which increases the risk of obesity and type 2 diabetes'. Main outcome measures. Participants viewed four UPF products displaying their randomly assigned labels. Participants indicated whether the product was UPF (primary outcome) and rated perceived healthfulness of the product, intentions to purchase the product, and perceived message effectiveness (secondary outcomes). Results. Identity warnings (70% correct) and health warnings (67% correct) both led to higher correct identification of UPF compared to control labels (54%, p<.001), with the identity warning having a larger impact than the health warning (p=.007). Compared to the control label, the identity warning and health warning both elicited higher perceived message effectiveness and lower perceptions of healthfulness and purchase intentions (p<.001 for all outcomes) with no significant differences between UPF labels. The impact of the health warning label (vs. the control label) on correct identification of UPF was greater for participants with high education (p=0.012) compared to those with low education, and participants with limited English proficiency (p=0.001). Conclusions: UPF warnings may help consumers identify UPFs and influence product perceptions and intentions.

Due to a high prevalence of obesity-related chronic diseases and an increasing use of injectable weight loss medications, a need for dietary consultations by registered dietitian nutritionists (RDNs) has been increasing. However, there is a paucity in RDNs who provide weight management services. The objective of this study is to gather insight on the dietary interventions and barriers in weight loss practice as reported by RDNs specializing in weight management. The survey contained 33 questions and four domains (current practice diet interventions and protocols, client demographics, practitioner demographics, and barriers). Descriptive statistics were used to evaluate results. Survey participants, RDNs (N=739), were recruited from Weight Management Dietetic Practice Group of the Academy of Nutrition and Dietetics. Weight management occupies most (69%) of surveyed RDNs work time. App use was the most common method of food record collection (n=299), and food record accuracy was the most prevalent cited barrier to weight loss magnitude (n=233). Most (n=253) RDNs reported seeing their typical client once a month with an average continued engagement of one month being the most prevalent (n=197). Lastly, most RDNs (81%, n=595) do not have a customary program or diet they refer clients to. In conclusion, improvements in technologically enhanced platforms for accurate diet record collection and patient education may benefit RDNs weight management practice and further research into reasons for patient attrition from weight loss counselling is warranted.

Introduction Acute malnutrition in children aged 6-23 months remains critical in Tigray, Ethiopia, where global acute malnutrition (GAM) rates have reached emergency levels. Small-quantity lipid-based nutrient supplements (SQ-LNS) show promise for prevention, but evidence from post-conflict settings is limited. Objective This study evaluated SQ-LNS effectiveness in preventing acute malnutrition and rightward shifting in the distribution of weight-for-height among young children in post-conflict Tigray, Ethiopia. Methods A non-randomized cluster trial enrolled 8,442 children aged 6-23 months across four districts. The intervention group (n=6,838) received daily 20g SQ-LNS sachets for six months plus behavior change communication; the control group (n=1,604) received standard nutrition programming. Primary outcomes were acute malnutrition prevalence (WHZ < -2 or MUAC < 12.5cm) and distribution of weight-for-height z-scores. Data were collected biweekly and analyzed using longitudinal comparisons and difference-in-differences (DiD) estimation. Results Acute malnutrition declined from 22.1% to 4.2% in the intervention group (17.9 percentage point reduction) versus 19.6% to 11.4% in controls (8.2-point reduction). Mean WHZ scores increased from -0.35 to +0.33 in the intervention group (gain of +0.68 z-scores), while controls improved from -0.79 to -0.63 (gain of +0.16). The net intervention effect (DiD) showed a 4.9 percentage point reduction in WHZ-defined GAM and a 9.7-point reduction in MUAC-defined GAM. Mean WHZ and MUAC increased significantly more in the intervention group (DiD: +0.52 z-scores and +3.88 mm, respectively). Critically, the entire WHZ distribution shifted rightward, indicating population-level nutritional improvement, not merely reduced caseloads. Conclusions Six months of daily SQ-LNS effectively prevented acute malnutrition and shifted the entire weight-for-height distribution rightward among young children in post-conflict Tigray. Benefits extended beyond treatment, lifting whole-population nutritional status and building resilience. Findings support SQ-LNS inclusion in post-conflict nutrition packages and highlight the importance of assessing distributional outcomes, not just prevalence, when evaluating nutritional interventions. Trial registration number This trial was registered as NCT06103084.

IntroductionBreastfeeding supports multiple aspects of child development and maternal health. However, research findings are often inconsistent due to methodological limitations, including inadequate control for sociodemographic factors, variation in feeding practices, health conditions across the life course, and heterogeneity in human milk (HM) composition. The Manitoba Interdisciplinary Lactation Center (MILC) is a globally accessible, bench-to-population research platform that enables integrated study of HM composition, maternal-child health, and the societal and structural determinants of lactation and HM feeding. Methods and AnalysisMILC combines cross-sectional questionnaire data and HM sample collection with longitudinal administrative data derived from provincial government databases. MILC recruits lactating parents currently feeding their HM to at least one child. Participants follow a standardized full breast expression protocol. All collected HM samples have their macronutrient profiles characterized and are bio-banked for unspecified future research. Questionnaires capture child and parent demographic, dietary and health characteristics, and detailed HM feeding practices. Administrative data include over 90 databases spanning health and social services utilization and education; these de-identified records are housed at the Manitoba Population Research Data Repository and linked with MILC study samples and data. MILC questionnaires and HM collection protocols can be customized to accommodate specific research projects (e.g. additional surveys or questions; snap freezing, addition of preservatives, cell or extra-cellular vesicle isolation, etc.). MILC began recruiting participants in October 2024 and is currently ongoing. Researchers may access MILC data and biospecimens subject to appropriate ethical approvals and data-sharing agreements. Ethics and disseminationMILC is approved by the University of Manitoba Human Research Ethics Board and the Provincial Health Research Privacy Committee. Participation is voluntary and based on informed consent. Research updates and findings will be disseminated via peer-reviewed journal publications, academic and clinical conferences, social media, public knowledge sharing events (e.g. information booths and virtual "Ask Me Anything" sessions), the MILC website (https://www.milcresearch.com) and the MILC Club (monthly meetings among researchers, trainees, healthcare providers, and community partners). MILC members also engage with agenda-setting organizations (e.g. Breastfeeding Committee for Canada, North American Board for Breastfeeding and Lactation Medicine) to accelerate translation of research knowledge into policy and practice. STRENGTHS AND LIMITATIONS OF THIS STUDYO_LIMILC combines low-burden cross-sectional human milk samples and questionnaire data with lifelong/longitudinal administrative data.

Background: Accurate dietary assessment is essential for precision nutrition and effective nutrition surveillance. However, portion size estimation remains a persistent challenge, particularly in culturally diverse regions such as Central Asia. Traditional self-reporting tools often yield inconsistent results due to communal eating practices and unfamiliarity with standard measures. Objective: To address these limitations, this study aimed to compare three methods: unassisted human judgment, visual food atlas assistance, and an artificial intelligence (AI) model, using Central Asian food items. Methods: In this cross-sectional study, 128 participants from Astana, Kazakhstan, visually estimated portion sizes of 51 foods and 8 beverages from standardized photographs. Participants were randomized into two groups: one using unassisted visual estimation and the other aided by a regionally tailored digital food atlas. Additionally, an AI model trained on Central Asian food images was evaluated. Actual food weights served as the reference standard. Accuracy was assessed using Mean Absolute Error (MAE) and Mean Absolute Percentage Error (MAPE) across food types and portion sizes. Results: The atlas-assisted group demonstrated the highest accuracy, with the lowest MAE (80.81g) and MAPE (44.76%) across all portions. The AI model showed promising results for average portions (MAE: 79.07g, MAPE: 67.91%) but underperformed on small portions, particularly for meat-based items. Unassisted estimates were the least accurate (MAE: 133.86g, MAPE: 79.40%). Across food categories, visual aids consistently improved accuracy, while AI demonstrated variability by texture and portion size. Conclusions: Culturally adapted visual atlases significantly enhance portion size estimation accuracy in non-Western, communal-eating contexts. While AI models hold promise for dietary assessments, particularly with standard portions and beverages, further refinement is needed for complex food items and small portion types. These findings support the integration of visual and AI-based tools into region-specific dietary monitoring strategies.

As plant-based (PB) diets become more common among UK children, understanding their nutritional adequacy and environmental impact is vital. This study assessed nutrient intake and dietary greenhouse gas emissions among children following omnivorous, vegetarian, and vegan diets. A cross-sectional analysis was conducted using three-day weighed food diaries from 39 UK children aged 2-12 years (omnivore n=15; and PB: vegetarian n=11; vegan n=13). Nutrients were analysed with and without supplementation using Nutritics software. GHGEs were calculated at the ingredient level (kgCO2e/day) and grouped by Eatwell Guide food categories. No dietary group met all nutrient reference values. Omnivores exceeded recommended intakes for saturated fat and free sugars while failing to meet the recommended intake for fibre, whereas PB children had intakes of these nutrients in the healthy range. PB diets were adequate in protein and vitamin B12 even in the absence of supplementation. Vegan children also met iron requirements from diet alone, whereas omnivore and vegetarian children did not meet iron targets without supplementation. Vitamin D intake was insufficient across all groups when supplements were excluded, with only vegan children achieving recommended levels through supplementation. Zinc requirements were met only by vegetarian children with the aid of supplements and were not met by vegan or omnivore children with or without supplementation. Iodine intake remained inadequate in vegan children even with supplementation. Mean daily GHGEs differed significantly between diet groups (p < 0.001): omnivores having the highest emissions, while vegans had the lowest emissions: 46% lower than omnivores, and 20% lower than vegetarians. Well-planned PB diets can meet most nutrient needs in UK children when supported by fortified foods and supplements, while substantially reducing dietary GHGEs compared with omnivorous diets. Shifting away from animal protein and dairy provides the greatest opportunity for improving both nutritional quality and environmental sustainability.

BackgroundOverweight and obesity are causing growing public health, economic and clinical burden, particularly within under-resourced communities. There is an urgent need to develop an in-depth understanding of experiences of weight management, and preferences for support within under-resourced communities, with a view to developing more effective weight management interventions. MethodsFocus groups were run in under-resourced communities using storyboarding; a method to facilitate inclusive communication (n=37). Thematic analysis was applied to textual and visual data, and a realist lens applied to provide in-depth insight into weight management experiences and needs. We believe this is the first study to use this combined methodology to explore weight management experiences and needs. ResultsCombining storyboarding with a realist lens, generated four themes. Living circumstances indicated that mental health, individual needs, and cost of weight management services were key contextual factors. Mechanisms of weight management identified emotional eating and portion control to be central to individual weight management. Yo-yo dieting centred on participants experiences of weight regain after attempting weight loss. Weight management intervention needs indicated psychological support was perceived as severely lacking, and the only route to attain sustained weight management. Offering both in-person and online support for weight management was considered important to reach more people. ConclusionMoving weight management support from short- to long-term and incorporating more robust psychological support would better serve the needs of people living in under-resourced communities who are overweight or obese. Ideally interventions should be multicomponent and tailored to individual needs and circumstances.

Introduction High consumption of ultra-processed foods (UPF) is associated with adverse health outcomes and weight gain. Despite increasing calls for behavioural strategies to reduce UPF intake, no theory-informed intervention targeting UPF reduction has been evaluated in UK adults in alignment with national dietary guidance. We assessed the feasibility, acceptability, and preliminary behavioural and clinical outcomes of a multi-component intervention designed to reduce UPF consumption (and increase physical activity (PA)/minimally processed food (MPF) intake). Methods In this exploratory single-arm pre-post study, adults (N=45) living with overweight or obesity and habitual UPF intake [&ge;]50% of total energy were offered a 6-month behavioural intervention following a controlled feeding phase (UPDATE trial, stage 1). The intervention was developed using the Behaviour Change Wheel and Capability, Opportunity, Motivation-Behaviour (COM-B) model and included one-to-one sessions with a behavioural scientist, tailored print and digital materials, peer-support meetings, and a moderated group chat. Feasibility outcomes included uptake, retention, and intervention fidelity. Secondary outcomes included COM-B constructs, dietary intake, PA, clinical and self-reported outcomes, and qualitative feedback. Results Uptake was 91% (41/45). Retention at 6 months was 68% (28/41), with 83% (34/41) providing follow-up data (intention-to-treat). Median attendance at one-to-one sessions was 86% (interquartile range (IQR): 57-100) with 56% (23/41) attending all sessions (per-protocol). Fidelity to core behaviour change techniques was high. At 6 months, COM-B scores improved for healthy eating (+7%, standard deviation (SD): 8; p<0.001) and physical activity (+5%, SD: 9; p=0.013). UPF intake decreased by 25% of total energy (95% confidence interval (95%CI): -32, -17), with a corresponding increase in minimally processed foods (+23%; 95%CI: 17, 29). Vigorous physical activity increased (+60 min/week, IQR: 0-180), weekday sitting time decreased (-61 min/day, SD: 110), and weight reduced by 3.8 kg (IQR: -8.5-1.0; p=0.001). Findings were similar in per-protocol analyses. Qualitative data indicated perceived improvements in wellbeing and habit formation. Conclusion This theory-informed intervention demonstrated good feasibility and acceptability and was associated with improvements in targeted behavioural mechanisms and health-related outcomes. A randomised controlled pilot trial is warranted to evaluate effectiveness and refine implementation.

Child undernutrition remains a major public health challenge in Kenya. Suboptimal feeding practices contribute significantly to persistent underweight and stunting. This study evaluated the effect of a community-based Positive Deviance Hearth (PDH) intervention on feeding practices among children aged 6-59 months in Sub County within a County of study. The study adopted a two-group pretest-posttest randomized experimental study design conducted for six months period, among 84 caregiver-child pairs in intervention and control groups. A multi-stage sampling was employed to identify study settings and participants. Structured and pretested questionnaires, 24-hour food recall questionnaires and meal diversity questionnaires were used for data collection at pre-intervention and post-intervention periods. Data was analyzed using R software v.4.5.2. The differences between intervention and control groups at baseline and endline were assessed using difference-in-difference analysis, relevantly summarized using adjusted DID estimates, 95% confidence intervals and p-values, with p<0.05 considered significant. The PDH intervention significantly improved feeding practices among children 6-59 months. Meal frequency increased for 9-23 months (DiD = +1.4; 95% CI: 1.2-1.7; p = 0.034) and 24 months and above (DiD = +1.2; 95% CI: 1.1-1.5; p = 0.017), and dietary diversity rose (DiD = +1.3; 95% CI: 1.1-1.9; p < 0.001). Nutrient-dense food consumption improved, including legumes (DiD = +32.6%; p < 0.001) and animal-source foods (DiD = +35.4%; p < 0.001). Energy and protein intake increased across all age groups (p < 0.05), and micronutrients iron, vitamin A, vitamin C also rose significantly (p < 0.05). The PDH intervention substantially improved caregiver feeding practices, increased dietary diversity, and enhanced macro- and micronutrient intake, demonstrating its effectiveness as a scalable, community-driven strategy for sustainably improving child nutrition in high-burden settings.

Although the co-occurrence of diarrhea and malnutrition is well documented, research has largely focused on the acute management of diarrheal illness. Despite its importance, longitudinal evidence characterizing post-diarrheal recovery trajectories is sparse. We sought to characterize post-diarrheal nutritional recovery trajectories among children aged 6-35 months who were malnourished at enrollment using data from the Enterics for Global Health (EFGH) Shigella Surveillance study (2022-2024). EFGH enrolled children aged 6-35 months presenting with medically-attended diarrhea and followed them at 4 weeks and 3 months post-enrollment. This analysis included children with baseline wasting, stunting, or underweight (z-score < -2) and complete anthropometric follow-up. Latent class mixed-effects models were used to identify distinct post-diarrheal growth trajectories based on changes in anthropometric z-scores over time. Multinomial modified Poisson regression models examined associations between baseline factors and trajectory membership. Among 9,480 enrolled children, 16.5% (n=1,561) were wasted, 22.7% (n=2,155) stunted, and 21.0% (n=1,994) underweight at baseline. Wasting showed greater recovery potential (80.8%) compared with stunting (38.5%) and underweight (40.3%). Recovery was shaped by factors across multiple levels. Clinical severity markers ( prolonged diarrhea, dehydration, and hypoxemia) increased the risk of nutritional failure. Age also influenced outcomes: infants were more likely to worsen, whereas older toddlers more often experienced stagnation. Interventions including exclusive breastfeeding, oral rehydration therapy, appropriate antibiotics, and zinc supplementation, improved outcomes, while unimproved sanitation undermined recovery. These findings highlight the need for integrated strategies combining infection control, nutritional rehabilitation, and water, sanitation, and hygiene interventions tailored to the childrens developmental stage. Key MessagesO_LIPost-diarrheal nutritional recovery is highly heterogeneous, with wasting showing the greatest potential for improvement, while stunting and underweight often result in persistent growth stagnation.

BackgroundCentral obesity is a critical public health issue linked to non- communicable diseases and long-term maternal health risks. Women beyond the postpartum period often face barriers to weight management, yet limited evidence exists on their specific challenges and the role of healthcare systems in addressing them. This study aimed to assess central obesity among women beyond postpartum period, focusing on the associated challenges and available health support systems. MethodologyA cross-sectional design was employed whereby 120 women (1 to 5 years postpartum), aged 18 - 49 years, attending selected one private and two government health facilities in Morogoro Urban District participated. Face-to-face interviews using semi-structured questionnaires and anthropometric measurements of waist and hip circumference were conducted. Data were recorded using Kobo digital Toolbox. Key findingsHigh prevalence of central obesity, with 68.3% of participants having a waist circumference above normal ([&ge;]80 cm) was observed. Although no socio-demographic factor assessed showed a statistically significant association with central obesity, trends indicated higher odds among older (OR=1.544; 95% CI, 0.084-28.557), married (OR= 1.730; 95% CI, 0.612-4.892) and higher income women (OR= 4.878; 95% CI, 0.367-64.818). Lifestyle behaviors such as low physical activity, poor dietary habits and lack of portion control were prevalent. 57.5% reported lacking information on weight and waist management. Despite attending health care facilities, 94.2% of the women had never received guidance from health providers regarding weight or central obesity management and 95% reported not receiving any form of support such as nutrition counseling or exercise recommendations. ConclusionThe study concludes that central obesity is highly prevalent among women beyond postpartum period and is influenced by poor lifestyle behaviors and inadequate healthcare system support. It recommends integrating weight management strategies into routine postpartum care and strengthening healthcare systems to offer tailored guidance and support to women after childbirth.

Abstract Background Between 2021 and 2022, primary care obesity management was entering the early diffusion phase of newer anti obesity pharmacotherapy, as GLP1 based treatments began reshaping expectations. However, it was unclear whether primary care clinicians and practice environments were prepared to deliver comprehensive obesity care. (1,2) Methods In 2021 to 2022, we surveyed 276 clinicians from three cohorts: an opt-in national physician panel (Cohort A), clinicians from an integrated health system (Cohort B), and clinicians from a rural accountable care organization (Cohort C). The survey, informed by formative patient and physician focus groups conducted in 2021, assessed current and desired competence, attitudes, confidence, perceived forces for change, and barriers to obesity care. Analyses were descriptive (means and standard deviations). Results Across cohorts, desired competence exceeded current competence. The largest gaps involved recommending behavioral interventions, developing comprehensive care plans, and providing ongoing obesity management support. Attitudes toward obesity care were generally favorable, while confidence that current practices reflected best practice was only moderate. Professional and personal forces for change were moderate, patient driven motivators were moderate to high, whereas social (peer/organizational) reinforcement was weak. Reported barriers extended beyond knowledge deficits to include patient engagement, competing demands, cost, and practical constraints. Conclusions At the threshold of the GLP1 era, primary care clinicians were motivated to improve obesity care but lacked consistent support to deliver comprehensive management. The relative absence of peer and organizational reinforcement suggests that readiness for change reflected not only individual knowledge and attitudes, but also the degree of peer and organizational reinforcement that supports comprehensive obesity care in routine practice.

Background: Severe acute malnutrition (SAM) remains a major public health problem among under-five children, particularly in low-income countries. Comorbidity, especially pneumonia and diarrhea, significantly increases the risk of morbidity and mortality among affected children. Methods: An institutional-based cross-sectional study was conducted from April 20 to May 20, 2024, among children aged 6-59 months admitted with SAM to public hospitals in North Shoa Zone, Ethiopia. A total of 394 participants were included using systematic random sampling. Data were collected through caregiver interviews and medical record reviews using a structured, pre-tested questionnaire. Data were entered into Epi Info version 7 and analyzed using Stata version 16.1. Logistic regression analyses were performed to identify factors associated with comorbidity. Statistical significance was declared at p-value < 0.05. Results: The prevalence of comorbidity (pneumonia and diarrhea) among severely acutely malnourished children was 15.48% (95% CI: 11.89-19.06). Children with low dietary diversity (<5 food groups) were twice as likely to develop comorbidity (AOR = 2.00, 95% CI: 1.09-3.98). Children of single mothers had higher odds of comorbidity (AOR = 3.00, 95% CI: 1.21-7.65). Additionally, very low perceived birth weight was strongly associated with comorbidity (AOR = 7.11, 95% CI: 1.43-35.48). Conclusions: A substantial proportion of children with SAM had comorbid pneumonia and diarrhea. Key predictors included poor dietary diversity, maternal marital status, and low birth weight. Strengthening integrated child health and nutrition interventions is essential to reduce comorbidity and improve outcomes among vulnerable children.

ImportanceCurrent guidelines from the World Health Organization, Centers for Disease Control and Prevention, and Academy of Breastfeeding Medicine recommend discarding all milk remaining in bottles immediately after infant feeding. However, these recommendations lack supporting microbiological evidence from studies of actual infant feeding, imposing substantial financial and emotional burden on the 78 million families worldwide who bottle-feed their infants. ObjectiveTo determine (1) the financial, emotional, and time burden associated with bottle feeding and parental milk disposal practices, and (2) bacterial growth in leftover human milk and formula under different storage conditions. Design(1) Cross-sectional online survey (January 2023-February 2024) and (2) prospective microbiological cohort study. Setting(1) Online survey, (2) infants recruited in Hannover, Germany Participants(1) Survey respondents (n=1056; 99% mothers) and (2) healthy, full-term, bottle-fed infants (n=44; 17 humanmilk, 27 formula) aged 0-12 months. Main Outcomes and MeasuresParental burden scores, milk disposal frequency, and bacterial colony-forming units (CFU)/ml in milk samples before feeding, immediately after feeding, and at 4, 8, and 24 hours post-feeding at 4{degrees}C and 20{degrees}C. ResultsAmong surveyed parents, 46% discarded leftover milk daily, yet 84% reported they would keep milk longer if deemed safe. In microbiological testing, median bacterial burden in humanmilk increased from 4200 CFU/ml (range 300-350,000) pre-feeding to 24,600 CFU/ml (range 1900-29,004,400) post-feeding, but showed no significant further increase at 4 hours (p=0.82) or 8 hours (p=0.64) when stored at either 4{degrees}C or 20{degrees}C. Formula showed similar stability: median CFU/ml increased from 0 (range 0-10,700) to 11,700 (range 1900-630,000) post-feeding, with no significant change at 4 hours (p=0.91) or 8 hours (p=0.73) at either temperature. Significant bacterial growth occurred only after 24 hours at 20{degrees}C (p<0.001). Conclusions and RelevanceBacterial burden in leftover infant milk remained stable below concerning thresholds for 8 hours when refrigerated and 4-8 hours at room temperature, challenging current guidelines that mandate immediate disposal. Evidence-based guideline revision could reduce financial burden and milk waste for families around the globe without compromising infant safety. Key PointsO_ST_ABSQuestionC_ST_ABSHow long is it safe to offer leftover milk in a bottle to an infant that has previously drunk from it? FindingsThe number of bacteria in leftover human milk or formula did not significantly increase from 0 to 8h post-feeding in milk bottles sampled from 44 infants, regardless of whether the milk was kept at room temperature or refrigerated. MeaningLeftover milk may be safely reoffered beyond the limits of the current guidelines.
