Introduction Education is a core social determinant of health for children and adolescents. Unfortunately, academic achievement, health, and wellbeing of adolescents have decreased in many developed countries in the past decade. The purpose of the Wellbeing and Education linkages in school-aged children (WELL-ED) study is to examine associations of school absences and academic achievement with use of school-based and community-based health and social welfare services. In addition, we will assess user experiences and multi-sector services pathways of school-aged children for a better understanding of how the service system could respond to the needs of children. Methods and analysis WELL-ED is a large population-based study that combines register data on school absences and educational support from municipalities with register data on healthcare and social service use collected from wellbeing services counties in Finland. The study cohort includes all children who attended mandatory education in public schools in Southern Finland in school year 2023-2024. A smaller cohort of adolescents in school year 8 was invited to complete a user experience survey. The primary outcomes of this study are related to equity of service use. Ethics and dissemination The Regional Committee on Medical Research Ethics of the Helsinki and Uusimaa Hospital District (2803/2024) has approved the WELL-ED study protocol. For the survey, adolescents in year 8 and parents of adolescents younger than 15 provided informed consent. Results will be published in peer-reviewed journals, summaries will be sent to participating municipalities and wellbeing services counties and press releases will be written on key findings.

Abstract Background: Schools are widely recognised as key settings for promoting childrens health behaviours. However, many schools struggle with the implementation and especially sustainment of health promotion programmes e.g. due to limited resources. Strengthening schools capacity for health promotion has therefore been identified as a central strategy for achieving better implementation and ultimately behaviour change outcomes among children. The fit4future Kids programme was developed as a large-scale, multi-component initiative in Germany that aims to promote childrens physical activity, nutrition, mental health, and responsible digital media use while simultaneously supporting schools in building structures for sustainable health promotion. Methods: This paper describes the intervention and evaluation protocol of the nationwide fit4future Kids programme implemented in several cohorts of German primary schools from Sept. 2022 to Sept. 2027. The intervention is based on the Health Promoting Schools framework and integrates established implementation and behaviour change frameworks, including the Consolidated Framework for Implementation Research, the COM-B model, and Behaviour Change Techniques. The programme combines curricular materials, environmental components, and structured implementation support to facilitate the integration of health promotion into everyday school practice. The evaluation follows a mixed-methods design involving multiple stakeholder groups, including school staff, parents, and children. Quantitative and qualitative data are collected to assess implementation processes, contextual factors, and programme outcomes. The large and diverse sample of 1,153 participating primary schools allows for the exploration of different implementation trajectories and the investigation of potential equity-related effects. Discussion: By combining evidence-based health promotion strategies with implementation science approaches, fit4future Kids provides a large-scale real-world example of how schools can be supported in implementing sustainable health promotion. The evaluation is expected to generate important insights into the implementation and potential effectiveness of multi-component school-based interventions and to inform future initiatives aiming to strengthen health-promoting school environments.

Background School stress and psychosomatic complaints are linked and increase in high-income countries, with differences between countries. Evidence of how these parameters develop in Italy, particularly through combined parental and self-reported perspectives across age and gender, is limited. Methods A population-based online survey investigated school stress and psychosomatic complaints in children and adolescents aged 6-19 years, analyzing proxy- and self-reported data based on standardized validated instruments. Data was stratified by gender and age for children (6-10), early adolescents (11-14), and late adolescents (15-19). Results For early and late adolescents, the gender gap was evident, with higher levels of stress and health complaints in late adolescent girls. In this group, 56% of the girls self-reported rather/high school stress, and 43% of the boys. Parents perceived school stress and psychosomatic problems of their children as less severe than adolescents themselves. Parents stated a higher effect of parental help with school problems, and a lower effect of physical activity and digital media use on their childrens psychosomatic problems. Physical activity was related to fewer psychosomatic complaints, especially in girls. Conclusions This study identified late adolescent girls as vulnerable group, underscoring the critical need for gender-specific early prevention strategies starting in childhood, particularly for families with lower socioeconomic status. Parental perspectives may underestimate adolescents stress levels and psychosomatic well-being. In early adolescence, less digital media use may prevent psychosomatic problems, in late adolescence, physical activity may be a preventive method. Further longitudinal investigations should put a special focus on self- and proxy-reported perspectives.

Background: The COVID-19 pandemic caused major disruptions to maternity care, breastfeeding support, and social networks. These changes may have increased the risk of postpartum depression, anxiety, and stress among breastfeeding mothers, a population that has been underrepresented in previous reviews. This systematic review and meta-analysis aimed to compare maternal mental health outcomes among breastfeeding mothers before and during the COVID-19 pandemic. Methods: We searched MEDLINE, EMBASE, AMED, Web of Science, WanFang Data, MedRxiv, WHO COVID-19 databases, and grey literature from database inception to December 2023. Eligible studies compared mental health outcomes in breastfeeding mothers before and during the COVID-19 pandemic using validated assessment tools, including the Edinburgh Postnatal Depression Scale (EPDS), Generalized Anxiety Disorder Scale (GAD-7), State-Trait Anxiety Inventory (STAI), or Perceived Stress Scale (PSS). Studies with fewer than 10 participants per group were excluded. Two reviewers independently screened studies, extracted data, and assessed risk of bias using the Joanna Briggs Institute checklist or Newcastle-Ottawa Scale, depending on study design. Random-effects meta-analysis was performed when at least two studies reported comparable outcomes. Results: Twenty-three studies involving breastfeeding mothers from 15 countries were included. Meta-analysis showed significantly higher depressive symptoms during the pandemic compared with the pre-pandemic period, measured by EPDS (standardized mean difference [SMD] = 0.21, 95% confidence interval [CI] 0.14 to 0.29). Maternal anxiety measured by GAD-7 was also significantly higher during the pandemic (SMD = 0.27, 95% CI 0.13 to 0.41). Findings for perceived stress were mixed across studies and could not be pooled because of heterogeneity in reporting methods. Limited evidence suggested that mother-infant bonding did not substantially decline during the pandemic despite increased maternal psychological distress. Conclusions: Breastfeeding mothers experienced increased postpartum depression and anxiety symptoms during the COVID-19 pandemic. These findings highlight the importance of maintaining breastfeeding support services, ensuring access to maternal mental health screening, and developing flexible models of postpartum care during future public health emergencies.

Background The study aimed to estimate healthcare costs associated with malnutrition in Swedish older adults. Methods We conducted a cohort study using data from the population-based Swedish National Study on Aging and Care in Kungsholmen (SNAC-K, N = 2982), a geriatric inpatient cohort of complex patients (N = 7680), and a cohort of individuals with cognitive impairment from the Swedish Register of Cognitive/Dementia Disorders (SveDem, N = 64192). At risk of malnutrition and malnutrition were ascertained by the Mini-Nutritional Assessment in SNAC-K and the geriatric inpatient cohort. In SveDem, body mass index was used for identifying malnutrition. Healthcare resource use was derived from regional and national registers. Associations between malnutrition and healthcare costs in 2024 Swedish kronor (SEK) were analyzed using two-part models and generalized linear regression models, adjusting for demographic and clinical factors. Findings In the community, at risk of malnutrition and malnutrition were associated with an increase in annual healthcare costs of 2267 SEK (95% CI: 64,4469) and 1846 SEK (95% CI: -6802,10493), respectively. In geriatric patients, healthcare costs over 6 months in individuals at risk of malnutrition and individuals with malnutrition were 60205 SEK (45613,74798) and 86619 SEK (68362,104875) higher than those without malnutrition. In people with cognitive impairment, malnutrition was associated with higher annual healthcare costs (22170 SEK, 95% CI: 15152,29188). Interpretation Both at risk of malnutrition and malnutrition are associated with higher healthcare costs in Swedish older adults. The study findings are important for informing future economic evaluations of malnutrition interventions in Swedish older adults.

Background Physical inactivity and sedentary behaviour are major contributors to non-communicable diseases (NCDs) and are unevenly distributed across populations, disproportionately affecting migrants and ethnic minority groups. Somali communities in the UK experience multiple structural and socio-economic disadvantages; however, evidence on physical activity and associated inequities remains limited. This study examined physical activity, sedentary behaviour, and related barriers and facilitators among Somali residents in Sheffield, United Kingdom. Methods A cross-sectional mixed-methods study was conducted among Somali adults (n = 238). Quantitative data were collected using the International Physical Activity Questionnaire Short Form (IPAQ-SF) and analysed using descriptive statistics and ordinal logistic regression. Qualitative data were obtained from two focus group discussions (n = 14) and analysed using inductive thematic analysis to explore socio-cultural, environmental, and structural determinants of physical activity. Results No statistically significant predictors of physical activity were identified in the adjusted analysis; however, consistent trends indicated lower activity levels among older adults and those in employment. Qualitative findings revealed multiple, intersecting barriers rooted in structural inequities, including migration-related lifestyle changes, reduced incidental activity, sedentary occupations, limited health literacy, language barriers, financial constraints, and gendered responsibilities. Cultural norms and environmental conditions further shaped behaviour. Facilitators included community-based, culturally tailored interventions, peer support, gender-sensitive programmes, and adaptation of traditional practices. Conclusion Somali residents in Sheffield face overlapping structural and socio-cultural barriers to physical activity that are not fully captured by quantitative measures alone. Equity-oriented, culturally competent, and community-led interventions addressing both systemic and behavioural determinants are essential to improve access to physical activity and reduce health inequalities and NCD risk.

Background Lifestyle interventions can increase the probability of remission of prediabetes to normal glucose tolerance, but their economic value remains unclear. We assessed the within-trial and lifetime-horizon modeled cost-effectiveness of intensive and conventional lifestyle interventions in risk-stratified participants with prediabetes. Methods A health economic evaluation was conducted alongside the 12-month multicenter PLIS trial (n=1,105). High-risk participants were randomized to intensive (HR-INT) or conventional (HR-CONV); low-risk participants to conventional lifestyle intervention (LR-CONV) or control (only short single consultation; LR-CTRL) with risk stratification based on insulin secretion, insulin sensitivity, and liver fat content. Within-trial analyses estimated incremental costs per additional remission to normoglycemia and per quality-adjusted life year (QALY). Lifetime cost-effectiveness was modelled using a four-state Markov Model. Findings At 12 months, HR-INT and LR-CONV increased remission compared with their respective comparators. The incremental cost per additional remission was {euro}7,081 (95% CI: dominated-47,277) for HR-INT and {euro}4,278 (1,312-11,793) for LR-CONV from a health insurance perspective. A willingness-to-pay of {euro}22,000 (HR-INT) and {euro}7,500 (LR-CONV) per additional remission corresponded to 90% probability of cost-effectiveness. Neither intervention was cost-effective in terms of QALYs gained within the 12-months period. Lifetime modelling suggested that both HR-INT and LR-CONV are not only cost-effective, but also cost-saving, relative to HR-CONV and LR-CTRL, respectively. Also in the probabilistic sensitivity analysis, most simulations indicated dominance (71.7% for HR and 88% for LR). Interpretation Based on short-term economic evaluation, the interventions assessed were cost-effective regarding additional participants with remission, not for incremental QALYs gained. Lifetime modelling suggests cost savings for both risk groups. Targeting populations with lifestyle interventions to achieve prediabetes remission seems to generate good value for money in the long term.

Background/Objectives: Children aged 6-24 months are highly vulnerable to malnutrition during conflict because they depend on breastfeeding, complementary feeding and functioning nutrition services. This study assessed nutritional status, socioeconomic correlates, maternal knowledge and primary health care centre (PHCC) nutrition service gaps in Gaza. Subjects/Methods: This cross-sectional study was conducted at Al-Daraj Martyrs Health Centre, one of the remaining functioning PHCCs in Gaza City during the study period, between late August and October 2025. Mother-child pairs were recruited by convenience sampling. Of 276 approached, 200 were included after non-response and exclusion of questionnaires with missing anthropometric data. Data came from structured interviews and medical records; haemoglobin results were available for 55 children. Results: Stunting affected 12.5% of children, underweight 20.1%, wasting 20.8%, and anaemia 63.6% of the haemoglobin-tested subsample. Underweight was associated with household food shortage (p=0.013) and previous malnutrition treatment (p=0.002), wasting with child age category (p=0.0024), and anaemia with paternal unemployment (p=0.020). Maternal knowledge and practice scores were positively correlated (r=0.177, p=0.012), but neither was independently associated with stunting or underweight in adjusted models. PHCC nutrition support was limited, with 71.0% of mothers reporting nurse-provided nutrition advice and 52.5% reporting growth-chart review. Conclusions: In this clinic-based sample from conflict-affected Gaza, malnutrition among children aged 6-24 months was substantial. The overall pattern suggests that nutritional risk was shaped more by structural deprivation and weakened PHCC support than by maternal knowledge alone. These findings underline the need to restore essential nutrition services and improve access to adequate food for young children.

Background Health inequalities between occupational or social class groups are pervasive and persistent. Healthcare professionals have better health outcomes compared to the general population. Whether this is a result of healthcare education, favourable socio-demographic characteristics among professionals or other effects is not certain and the extent to which single healthcare occupational groups exhibit inequalities is unknown. We have described self-rated health and quantified geographic health inequalities among a single occupational group of Registered Nurses compared to the general population. Methods We analysed nationally representative samples from the 2011 UK Censuses across England, Wales and Scotland in the Office for National Statistics Longitudinal Study and Scottish Longitudinal Study. Self-rated health and socio-demographic characteristics for the study population are described. Inequalities in health by area deprivation among Registered Nurses and the General Population are quantified. Logistic regression analysis was used to assess the association between Nurse status and self-rated health, adjusting for socio-demographic variables. Results Among economically active, working age adults (n = 478,802), we identified 9,180 Registered Nurses resident in England, Wales and Scotland. 59% of Registered Nurses reported very good self-rated health, with only 1% reporting poor or very poor health. A smaller proportion of Registered Nurses reported less than good health than the General Population at every level of area deprivation and had smaller absolute (4.1 percentage points vs. 9.1) and relative (RR: 1.5 vs. 2.0) inequalities between residents in the most and least deprived areas. Registered Nurses have an increased likelihood of reporting good or better health compared to the general population (Scotland OR: 1.3, 95% CI: 1.2 - 1.5, England & Wales OR: 1.4, 95% CI: 1.3 - 1.5) after adjusting for socio-demographic factors. Discussion Registered Nurses report better health compared to the general population and have smaller inequalities in health by area deprivation. However, unfair and avoidable geographical differences in health are present even in this socioeconomically privileged professional group. After adjusting for socioeconomic and demographic factors, the positive association between being a Registered Nurse and having good self-rated health remained.

Type 2 Diabetes (T2D) is a growing public health burden in West Africa, yet the effectiveness of lifestyle interventions for glycemic control in this region remains unclear. This systematic review and meta-analysis evaluated the impact of lifestyle interventions on Fasting Blood Glucose (FBG) and Glycated Hemoglobin (HbA1c) levels among adults with T2D in West Africa. A systematic search of PubMed, Scopus, Africa Journals Online, and Cairn.info was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) and quasi-experimental studies evaluating lifestyle interventions (physical activity, dietary modification, and combined/educational interventions) for glycemic control in adults with T2D in West Africa were included. Meta-analysis was performed via a random-effects model with restricted maximum likelihood (REML) estimation, using mean differences (MD) as the effect measure for both FBG and HbA1c outcomes. Heterogeneity was assessed via I2 statistics, and sensitivity, subgroup, and meta-regression analyses were conducted to examine potential moderators of the observed heterogeneity. Ten studies comprising 645 participants were included. Six studies reported FBG outcomes; however, two were excluded from the FBG meta-analysis due to missing control group post-test values and absence of a control group respectively, leaving four studies for pooling. A separate set of four studies contributed to the HbA1c meta-analysis. For FBG, lifestyle interventions were associated with reduction in FBG levels (pooled MD = -1.81 mmol/L, 95% CI: -2.33 to -1.30, p < 0.001), with moderate heterogeneity (I2 = 50.76%). The certainty of evidence assessed using the GRADE approach was rated as low for FBG outcomes and very low for HbA1c outcomes, reflecting concerns about imprecision and inconsistency across studies. Leave-one-out sensitivity analysis confirmed robustness of this finding, with estimates ranging from -1.707 to -2.087 mmol/L. Neither intervention duration nor sample size significantly moderated FBG effect sizes, with the model explaining approximately 15.7% of observed heterogeneity. For HbA1c, lifestyle interventions were also associated with reduction in HbA1c levels (pooled MD = -1.044%, 95% CI: -1.594 to -0.495, p = 0.0002), though heterogeneity was exceptionally high (I2 = 98.08%), limiting interpretability of the pooled estimate. Exploratory meta-regression identified intervention duration and sample size as statistically associated with HbA1c effect size, though the model was saturated given the small number of studies and findings should not be interpreted as confirmatory evidence of moderation. Conclusion: Lifestyle interventions, including supervised physical activity, dietary modification, and community-based diabetes education, were generally associated with improvements in glycemic control among adults with type 2 diabetes in West Africa. Evidence was more consistent for fasting blood glucose, while findings for HbA1c were highly heterogeneous and should be interpreted with caution. These results suggest potential benefit, but variability across studies highlights the need for more standardized and rigorously designed trials in the region.

BACKGROUND: The UK National Institute for Health and Care Excellence recommends routine enquiry about domestic violence and abuse (DVA) in maternity care. We aimed to explore patterns and predictors of DVA enquiry during routine first antenatal care ( booking) appointments with midwives in South East London. METHODS: We conducted an observational cohort study using cross-sectional data collected through the St Thomas Hospital midwifery service between 1st January 2019 and 31st March 2023. Pseudonymised data were extracted from maternity records, comprising demographics, mental and physical health information, social factors, and DVA enquiry. We used linear mixed modelling to test associations between predictors and DVA enquiry. RESULTS: The dataset comprised 7,932 booking appointments with 7,007 women (median age: 32 years; ethnicity: 52% White, 27% Black, 7% Asian, and 15% other). Enquiry was made about current experiences of DVA in 79.4% of appointments. Black-identifying women (OR=1.28, 95% CI [1.11,1.46]) and those born in Sub-Saharan Africa (OR=1.37 [1.14,1.64]) were more likely to be asked than white-identifying and UK-born women. Single women were more likely to be asked than married or cohabiting women (OR=1.22 [1.08,1.38]). Those living in more deprived neighbourhoods were more likely to be asked (OR=1.07 [1.01,1.14]). Multivariable modelling found that being born in Sub-Saharan Africa or Southern Europe, and living alone but with additional support were all associated with increased DVA enquiry, while being born in North America or requiring an interpreter were associated with decreased enquiry CONCLUSIONS: Despite recommendations for routine DVA enquiry during all booking appointments, a substantial proportion of pregnant individuals were not asked between 2019 to 2023. Predictors of DVA enquiry reflected practical barriers (e.g. language), and known or perceived predictors of DVA risk (e.g. deprivation). Our findings suggest that midwives consciously or unconsciously prioritise DVA enquiry for women they believe are at greatest risk, against national guidelines.

Background: The ECAIL trial, launched in 2017, targets hard-to-reach families and evaluates a multicomponent childhood obesity prevention intervention. At a maternity hospital in Lille, France, healthcare providers screened pregnant women experiencing social vulnerability, and dietitians delivered a home-based intervention until age 2. The COVID-19 pandemic led to a six-month suspension in 2020. This study compared eligibility and participation before the pandemic and after resumption, and examined how the pandemic and subsequent cost-of-living crisis shaped implementation and reach. Methods: We analyzed 5,744 eligibility questionnaires distributed at the maternity ward. Inclusion criteria included [&ge;]1 indicator of social vulnerability (e.g., socioeconomic disadvantage, precarious housing, or social isolation). To capture implementation experiences, a psychosocial researcher conducted a focus group with six dietitians delivering the intervention; it was recorded, transcribed, and analyzed thematically focusing on reach, acceptability, and adaptation. Results: Eligibility increased from 29.7% (n=955) prepandemic to 33.6% (n=849) after resumption, while the distribution of vulnerability criteriaremainedsimilar across periods:78.3% received social/medical benefits; employment was not the main source of household income for 58.7%; 24.4% experienced financial hardship; 14.7% reported social isolation; 6.0% lived in precarious housing; and 19.0% had three or more vulnerabilities. Participation among eligible women remained stable (24.6%; n=443). Qualitative findings indicated dietitians satisfaction and participants enthusiasm for the resumption of home visits, particularly in addressing social isolation. After resumption, the introduction of a pre-visit COVID-19 questionnaire reduced missed appointments. Converging qualitative and quantitative findings indicated sustained, and in some cases strengthened, provider engagement despite pandemic-related strain on hospital services. Conclusions: This study shows that a complex intervention can maintain reach and acceptability through adaptive implementation under major contextual disruptions.The rapid resumption of home-based services emerged as a robust strategy for engaging and retaining socially disadvantaged families, highlighting the importance of flexible, context-sensitive approaches during social and economic crises.

Background: Many mental health problems originate in childhood, highlighting the need for early preventive approaches. Preventive services to promote children's mental health are offered in the health, education, and social sectors (H-E-S) but are often not used by certain at-risk groups or early enough. To identify children at-risk and provide needs-oriented support, professionals from all sectors must be well trained, collaborate closely to refer to specialized services for specific mental health problems or risk factors, and understand the regional psychosocial support system and its services. A comprehensive approach to preventing mental health problems requires structured planning and a systematic overview of all institutions and services in the region and their collaboration. This study aims to map the preventive mental health and psychosocial support service system and the collaboration between institutions across three sectors (H-E-S) in two exemplary city districts. The study is integrated into a whole-district approach to child mental health promotion that is being implemented in one of the researched city districts, and its results will inform further activities there. Methods: We use a mixed-methods approach, combining qualitative interviews with a quantitative survey to map psychosocial services for children aged 4 to 10 and their families across the H-E-S sectors in two socioeconomically disadvantaged city districts in East and West Germany. All institutions that potentially offer psychosocial services for children and families will be approached to recruit professionals (e.g., schools, practices, counseling centers). To understand the regional psychosocial support system, we will analyze existing services and their characteristics (e.g., target groups, intervention types) descriptively. Social network analysis will be applied to gain an in-depth understanding of collaboration between institutions, to identify potential gaps in services and pathways, and to inform an intervention aimed at improving interinstitutional and intersectoral collaboration. Discussion: To our knowledge, this is the first study to comprehensively analyze regional preventive psychosocial support systems for children and families across sectors at the community level. Previous mappings of psychosocial services have focused on a single sector (e.g., health) or specific diagnoses only. The psychosocial preventive landscape spanning the H-E-S sectors involves complex financing structures and referral logics. Understanding the characteristics of the existing support landscape requires a systematic and comprehensive approach. Our study advances service mapping and operationalization methods in public health research. Additionally, the findings will inform recommendations for improving comprehensive prevention approaches in the selected city districts.

Objectives and study: This study aimed to examine predictors of post-partum maternal mental health (MMH) and coping during COVID-19 lockdown across seven countries (the UK, China, Japan, Malaysia, Mexico, Argentina, and Thailand). Methods: An anonymous questionnaire, developed in the UK in English and translated into local languages, was used in 2021-2022 to collect data on MMH and perceived coping ability from women aged [&ge;]18 years with an infant born before or during lockdowns. Five MMH components (worry, sadness, loneliness, difficulty relaxing, annoyance) and coping were assessed on a 4-point Likert scale, then dichotomised. MMH and coping were compared across countries using Chi-square tests with post-hoc pairwise comparisons conducted via Bonferroni-adjusted z-tests. Predictors of MMH and coping were examined using multivariable logistic regression. Results: A total of 7,650 women were analysed. Younger infant age, higher income, walking and exercise, and level of support were associated with better MMH and coping, whereas higher education was associated with better coping but poorer MMH. MMH and coping differed across countries (all p<0.001), which remained after adjusting for covariates: mothers in Asian countries reported better MMH, while those in the UK and Thailand reported better coping. Conclusions: Postpartum MMH and coping during lockdown were shaped by both individual and contextual factors. Findings highlight cross-country differences and underscore the need to strengthen maternal support system during future disruptions to perinatal care.

Mental health problems, including emotional problems, are linked to adverse educational outcomes among children and adolescents. This study examines the association between early onset of mental health problems generally, and emotional problems specifically, at ages 5-14, and outcomes from the General Certificate of Secondary Education (GCSE), a secondary education qualification, at age 16 for 4,783 students in England, using the Millennium Cohort Study dataset linked to the National Pupil Database. We found that the onset of mental health problems at ages 5, 7, 11 and 14 had a significant and negative association with all GCSE outcomes. We also found negative associations between early onset emotional problems and GCSE outcomes, although results were most stark for emotional problems that onset at age 11, with statistically significant negative associations with all GCSE outcomes. School absence was identified as a potential mediator of the negative association. Furthermore, this study found that the potential loss of productivity related to mental health problems in general and emotional problems in particular was over 23,000 sterling and 11,000 sterling per affected individual, respectively, which could translate into approximately 2.57 billion sterling and 1.6 billion sterling, respectively at the population level for England. These findings highlight the importance of early intervention for children and adolescents with mental health problems to improve educational and future outcomes.

Background Smartphone ownership among UK adolescents is near universal. Teachers report phones increasingly being involved in classroom disruption, and misuse during school hours is among the more common serious behavioural issues in secondary schools. Evidence on whether restrictive policies improve behaviour, attainment, or wellbeing remains limited. Objectives The primary objective is to assess the impact of a lockable smartphone pouch on educational attainment and behaviour. Secondary objectives are to assess impacts on general functioning, psychological wellbeing, and school level indicators such as exclusions, and to examine whether effects differ for pupils who may be most at risk. Methods We will conduct a mixed methods cohort study in secondary schools across Northern Ireland and England during the 2025 to 2026 academic year. The quantitative component uses a serial cross sectional design. Students will complete an online questionnaire at 0, 4 weeks, and 8 weeks, covering homework completion, classroom disruption, participation in PE and extracurricular activities, peer interaction during break, and patterns of smartphone use. Measures include the Strengths and Difficulties Questionnaire (SDQ), the Revised Child Anxiety and Depression Scale (RCADS), the short form of the Smartphone Addiction Scale (SAS SV), and the Bergen Social Media Addiction Scale (BSMAS). Each participating school will also supply half termly aggregate data on exclusions, detentions, CAMHS referrals, counsellor visits, and parent visits between September 2023 and May 2026. Assuming 90% power, a two-sided type 1 error of 0.05, an intracluster correlation of 0.02, and 25% loss to follow up, we aim to recruit a minimum of 3,200 students from six or more schools to detect a small effect (Cohen's d = 0.2) on SDQ hyperactivity score. Continuous outcomes will be analysed with linear regression and binary outcomes with logistic regression. Prespecified subgroup analyses cover SEN or neurodivergent status, area level deprivation, and which phone policy is in place at each school. Qualitative analyses comprise focus groups with students and staff at each participating school and semi-structured interviews with school leads. Transcripts will be coded both inductively and deductively and analysed thematically with Braun and Clarke's six phase approach. Ethics and Dissemination The study has been approved by the King's College London Research Ethics Committee. A Data Protection Impact Assessment has been agreed with the Northern Ireland Department of Education. Findings will be published in peer reviewed journals and shared with participating schools, parents, and policy makers to inform smartphone policy in schools.

Background: Mortality rates have declined across most high-income countries for decades, but recent evidence suggests a slowdown in improvements or a shift to increasing mortality, particularly among working-age populations. The international distribution and drivers of these trends remain incompletely understood. Methods: Mortality trends during 2012-2019 were analysed using all-cause and cause-specific data from 30 countries. Trends were estimated via linear regression. K-means clustering with Dynamic Time Warping identified countries and ICD-10 chapters with similar temporal trajectories. Results: Trends varied substantially by nation. While Japan, Switzerland, and the Republic of Korea maintained consistent declines in all-cause mortality rates, increases were concentrated in the United States, Canada, and the United Kingdom, most prominently in persons aged 30-59 years. However, cause-specific analysis showed that rising mortality was not confined to these countries: most countries exhibited increases in at least one ICD-10 chapter, with several European countries showing increases across multiple chapters. Across countries, a small set of causes recurred among increasing trends, including external causes (self-harm, drug poisoning) at younger ages and chronic conditions (cardiovascular and liver diseases, specific cancers) in mid-life. Notably, ill-defined causes of death consistently appeared among the increasing causes across countries and age groups. Conclusions: Mortality increases in the 2010s were geographically more widespread than previously recognized. The recurrent rise in mortality from ill-defined causes suggests that an important component of mortality change remains poorly characterized. These findings indicate that stalled health progress is a systemic challenge across many high-income societies.

Abstract Objective: This study aimed to assess the magnitude of undernutrition and associated factors among pregnant women attending public health facilities in the Goba district, Bale zone, Oromia Region, Ethiopia, 2022. Design: Institution-based, cross-sectional study design was used. Setting: The study was conducted in selected public health facilities from May to June 2022. Participants: The study population consisted of pregnant women who lived for at least 6 months in the study area and who attended antenatal care follow-up at selected public health facilities during the study period. Pregnant women who lived for less than six months in the study area and those who were critically ill were excluded from the study. Results: 487 respondents participated in this study with a 100% response rate. More than half (50.7%) of pregnant mothers were undernourished. The significant factors associated with maternal undernutrition during pregnancy in this study were mothers with no formal education (AOR = 5.050; 95% CI: 1.470- 17.346), a history of illness during pregnancy (AOR = 2.089; 95% CI: 1.246-3.504), and eating frequency of meals less than or equal to three times per day (AOR = 3.292; 95% CI: 1.040- 10.42). Poor nutritional knowledge (AOR = 5.588; 95% CI: 2.921-10.689), poor household (HH) wealth status (AOR = 4.774; 95% CI: 2.216- 10.285), and mothers who had >= 4 pregnancies were included (AOR = 0.852; 95% CI: 342-0.989). Conclusion: The magnitude of Undernutrition among pregnant women was 50.7%. Significant associations with Undernutrition were found in mothers with no formal education, poor dietary knowledge, a meal frequency of three or fewer times per day, a history of illness during pregnancy, lower and medium household wealth status, and those who had experienced four or more pregnancies while attending antenatal care (ANC) services at public health facilities.

Background Large-for-gestational-age (LGA) and macrosomic newborns are at increased risk of adverse perinatal outcomes, including death, yet the burden of neonatal mortality associated with these conditions in low- and middle-income countries (LMICs), where ongoing nutritional and epidemiological transitions suggest their prevalence will rise, remains poorly quantified. In this study, we quantify the neonatal mortality risk associated with LGA and macrosomia from 16 subnational birth cohorts in low- and middle-income countries between 2000 and 2017. Methods and findings This is an individual-participant meta-analysis to estimate neonatal mortality rates (NMRs) and relative risks among LGA infants (>90th and >97th percentile birth weight-for-gestational-age using INTERGROWTH-21st) versus appropriate-for-gestational-age (AGA, 10th-90th percentile) infants. Macrosomic ([&ge;]4000 g and [&ge;]4500 g) neonates were compared with those weighing 2500 g-3999g. Missing birth weights were imputed using recalibration and multiple imputation methods. We used random effects meta-analysis to pool relative risks. Median prevalences of LGA >90th and >97th percentile were 5.3% (interquartile range 3.6-8.2) and 2.6% (IQR 1.3-4.5), respectively; macrosomia ([&ge;]4000 g and [&ge;]4500 g) prevalences were 1.0% (IQR 0.3-3.1) and 0.06% (IQR 0.0, 0.30), respectively. Mortality was highest among preterm plus LGA infants (61.3 per 1000). LGA infants in the >90th percentile had over twofold increased mortality compared with appropriate-for-gestational-age infants (RR: 2.46; 95% CI: 1.86-3.25), while >97th percentile infants had a higher risk (RR: 3.77; 95% CI: 2.50-5.69). Term LGA >97th percentile infants also showed elevated mortality (RR: 3.14; 95% CI: 1.58-6.22). For LGA >97th percentile, the risk was higher in the early neonatal period (RR: 2.71; 95% CI: 1.92-3.82) than late (RR: 1.69; 95% CI: 1.22-2.34). There was no overall association between macrosomia ([&ge;]4000 g) and neonatal mortality. Population attributable fractions were 7.2% for LGA >90th percentile and 0.4% for macrosomia ([&ge;]4000 g). Conclusions Neonatal mortality risks were elevated among LGA infants in low- and middle-income countries, particularly at extreme values (>97th percentile) and during the early neonatal period. Macrosomia showed weaker, less robust associations. Although LGA prevalence is currently low ([~]5%) and contributes less to neonatal mortality than small newborns, ongoing nutritional and epidemiological transitions suggest increasing prevalence. This highlights the need for strengthened surveillance, monitoring, and improved delivery planning to ensure that no population is left behind.

Background: Maternal micronutrient deficiencies (MNDs) and inflammation contribute to adverse birth outcomes While the individual effects of MNDs have been studied, the consequence of co-occurring MNDs remains unclear. Objectives: To examine the associations between maternal micronutrient deficiencies and inflammation with adverse birth outcomes (ABOs). Methods: Data from 5,408 pregnant women across 11 datasets from 10 countries were analyzed. Descriptive analyses explored the distribution of MNDs (iron, vitamin A, zinc, serum folate, vitamin D, and vitamin B12) and inflammation (c-reactive protein >5 mg/L or -(1)-acid glycoprotein > 1g/L) by maternal characteristics (age, height, education, socioeconomic status [SES]) using chi-square tests. Associations of 1) single MNDs and inflammation and 2) co-occurring MNDs (2 deficiencies at a time) with low birth weight (LBW, < 2500 g), preterm birth (PTB, < 37 wks), and small-for-gestational age (SGA, < 10th percentile for gestational age), were examined using modified Poisson regression to estimate relative risk (RR), adjusting for age, SES, and dataset. Results: Young maternal age and short height were associated with up to 9.7% and 25% higher prevalence of MNDs and inflammation, respectively. Lower education and SES level were associated with higher prevalence of Vitamin B12 deficiency. Women with folate deficiency had an increased risk of LBW (RR [95% CI]: 1.22 [1.06, 1.39]). Co-occurring MNDs for folate and vitamin B12 were also associated with increased LBW risk (1.38 [1,1.9]) as was folate deficiency without iron (1.28 [1.09, 1.51]) or vitamin B12 deficiency (1.67 [1.09, 2.56]) compared with mothers without either deficiency. Iron deficiency without vitamin B12 deficiency was associated with a reduced LBW risk (0.4 [0.2, 0.79]). Conclusion: Maternal MNDs, especially folate and vitamin B12, are linked to adverse birth outcomes. Complex nutrient interactions highlight the need to explore these relationships to improve maternal and neonatal health interventions.
