Background/Objective: Seasonal upper respiratory tract infections (URTIs) are common in children and contribute to absenteeism and reduced quality of life. Over-the-counter treatments show limited efficacy and may cause adverse effects, thus warranting the need for natural alternatives. This study evaluated the efficacy of a whole-fruit supplement derived from boysenberry and apple (BerriQi) in reducing symptom severity and duration in school-aged children with URTIs using the Wisconsin Upper Respiratory Symptoms Survey for Kids (WURSS - K). Methods: In this double-blind, randomised, placebo-controlled study, 84 children aged 5 -13 years with URTI-associated school absence were assigned to receive BerriQi or placebo (two chewable tablets daily) for 14 days. Outcomes included the severity and duration of global illness, composite symptom and function scores. Results: Both groups showed progressive reductions in global illness severity, symptom, and function score over 14 days. However, the BerriQi group consistently reported lower scores across all outcomes. While global illness severity did not differ significantly between groups, total symptom severity was significantly reduced with BerriQi (P=0.04), and functional scores showed a trend toward improvement (P=0.05). The BerriQi group experienced fewer sick days compared with placebo (8 vs. 11 days) and demonstrated a higher likelihood of functional recovery (HR = 1.79, 95% CI: 1.09 - 2.91; P=0.02). Conclusions: These findings suggest that BerriQi may serve as a promising natural paediatric supplement for alleviating respiratory illness symptoms and supporting faster functional recovery, potentially reducing school absenteeism associated with upper respiratory tract infections (URTIs).

Background Italy experiences a substantial heat-related mortality burden, but evidence on cause-specific mortality across its heterogeneous climatic settings remains limited. We aimed to quantify cause-specific mortality attributable to summer heat in Italy at national and ecological region levels and to map its distribution across municipalities. Methods We analysed daily deaths classified by underlying cause in eight ICD-10 groups among individuals aged 18-64 years and 65 years or older across 7,864 municipalities during June-August, 2004-2023. Mortality data were linked to area-weighted ERA5-Land daily maximum temperature. Nonlinear temperature-mortality associations were estimated with Bayesian hierarchical Poisson models, fitted separately for each cause, age group, and ecological region, with municipality-level attributable fractions. Findings High temperatures were associated with mortality from a broad range of causes, particularly among individuals aged 65 years or older. Among the study population, heat-attributable fractions were highest for nervous system diseases (14.93%, 95% credible interval 14.22-15.69) and mental and behavioural disorders (14.47%, 13.55-15.39). Circulatory diseases accounted for the largest absolute burden, with 85,524 heat-attributable deaths (82,762-88,271) across the summers of the 20 years considered. Interpretation The mortality burden associated with summer heat in Italy extended well beyond circulatory and respiratory diseases, highlighting the relevance of a broader range of health outcomes. These findings support heat-health strategies that account for cause-specific and geographical differences in heat-related risk, with greater consideration of neurological and mental health outcomes alongside established cardiorespiratory risks.

Healthcare workers face substantial occupational demands and exposure to respiratory infections during winter, but evidence that probiotics improve their health and wellbeing remains limited. This exploratory, double-blind, randomised, placebo-controlled trial assessed whether daily Lab4 supplementation affected upper respiratory tract infection (URTI) frequency and supported wellbeing in 104 healthcare workers. Daily diaries recorded symptoms defining URTI episodes, general-practitioner visits, illness-related work absence and antibiotic use. Wellbeing was assessed at baseline and weeks 8 and 16, and faecal microbiota were assessed using 16S rRNA gene sequencing. Participants receiving Lab4 reported better wellbeing than those receiving placebo. For probiotic versus placebo, the risk ratio (RR) for URTI occurrence was 0.60 (95% confidence interval [CI]: 0.30-1.20; p=0.1477), the incidence rate ratio (IRR) for episodes was 0.58 (95% CI: 0.27-1.23; p=0.1581), and the mean ratio for episode duration was 0.98 (95% CI: 0.72-1.32; p=0.8776). For general-practitioner visits, the RR for at least one visit was 0.48 (95% CI: 0.21-1.07; p=0.0737) and the IRR was 0.44 (95% CI: 0.18-1.06; p=0.0677). For illness-related work absence, the RR for at least one day absent was 0.75 (95% CI: 0.18-3.22; p=0.6991) and the IRR for absence days was 0.74 (95% CI: 0.16-3.32; p=0.6914). For antibiotic use, the RR for any use was 0.48 (95% CI: 0.20-1.18; p=0.1111) and the IRR for antibiotic-use days was 0.42 (95% CI: 0.16-1.12; p=0.0820). No significant between-group differences in gut microbiota were detected in the subset providing faecal samples. Illness-related estimates generally favoured Lab4, although between-group differences were not statistically significant. These exploratory findings support evaluation in a larger, prospectively powered trial.

Objectives: To estimate the prevalence of Post-Exertional Malaise (PEM) among adults with prior COVID-19 and associated mental health and disability outcomes. Methods: We conducted a cross-sectional analysis of data from a survey of 9,620 adults with prior COVID-19 in New York City, collected May - June 2024. PEM was measured with the DePaul Symptom Questionnaire - Post Exertional Malaise, categorized by symptom duration (< 14 vs. [&ge;]14 hours). Weighted prevalence estimates were stratified by socio-demographic and clinical characteristics. Modified Poisson regression was used to assess the association of PEM with depression, anxiety, and disability. Results: The prevalence of PEM symptoms was 20.9% overall and 4.0% with symptom duration [&ge;]14 hours, representing over 800,000 New Yorkers affected and over 150,000 who meet a diagnostic criterion for ME/CFS. PEM prevalence was higher among women, transgender and non-binary adults, people of color, and lower educational attainment, chronic comorbidities, or disabilities. PEM was associated with 3 - 4 times higher prevalence of mental health outcomes and 4 - 5 times higher disability scores. Conclusions: PEM symptoms were common and strongly associated with disability and adverse mental health. Screening, pathways to care, and supportive policies are needed to mitigate long-term consequences, particularly among marginalized populations.

Background: Childhood cancer survivors (CCS) are at elevated risk of chronic health conditions. Sufficient physical activity and sleep, and limited sedentary behavior mitigate those risks, but device-based assessments of these behaviors among CCS are scarce. We described physical activity, sedentary behavior, and sleep among CCS using thigh-worn accelerometers and examined associated factors. Methods: We included participants of the 2024-2025 Swiss Childhood Cancer Survivor Study questionnaire wave who consented to wear an activPAL4 accelerometer continuously for eight days. Using ActiPASS, we derived physical activity types and intensities, sedentary behavior, and sleep. We stratified analyses by age (children: 5-17 years; adults: [&ge;]18 years). Results: 108 CCS (68 children, 40 adults) pariticipated. Children accumulated a median of 85 minutes/day of moderate-to-vigorous physical activity [IQR 57-107] and 578 minutes/day sedentary behavior [516-625]; adults 78 [61-100] and 603 minutes/day [522-650]. Both groups spent 4-5 hours/day in sedentary bouts [&ge;]30 minutes. Children slept 466 minutes/night [418-499], and adults 435 [407-488]. Only 9% of children and 20% of adults met recommendations for physical activity, sedentary behavior, and sleep simultaneously. Radiotherapy was associated with lower physical activity among children and higher sedentary time among children and adults. Older children achieved less physical activity and sleep, and had more sedentary time. Conclusion: CCS engage in extensive sedentary behavior, and especially in long uninterrupted sedentary bouts. Many sleep less than recommended. Healthcare practitioners should prioritize promoting physical activity among adolescent survivors and particularly those treated with radiotherapy, and support all survivors in improving sleep duration and reducing sedentary time.

Introduction: Current guidelines on physical activity (PA) and sedentary behaviour (SB) are based on self-reported questionnaire data, which are prone to recall bias and measurement error. As such, they provide limited guidance on the intensity, frequency and duration of activities. To improve and accelerate research on the health benefits of a physically active lifestyle and inform future guidelines, large-scale accelerometry in population-based studies is needed. The ActiveLIFE cohort study aims to create a comprehensive, deeply-phenotyped dataset of thigh- and wrist-worn accelerometry in relation to health characteristics and outcome data that can be used to accelerate lifestyle and prevention research. Methods and analysis: ActiveLIFE is an add-on study to the 4th assessment wave of the Lifelines Biobank study, aiming to collect ~60,000 accelerometry measurements. Lifelines participants aged [&ge;]8 years old will be invited to wear a triaxial thigh-worn accelerometer (Axivity AX3, settings: 100 Hz, 8g) for 8 consecutive days. Morover, to evaluate how wear location impacts effect estimates, a subsample of at least 10% will be asked to wear both a thigh- and wrist-worn accelerometer. Raw accelerometry data will be processed into PA metrics, including steps per day, time spent in moderate-to-vigoruous PA, light-intensity PA, SB, and sleep and enriched with data on demographics, body composition, health status, medication use, lifestyle characteristics, biomarkers, cognitive function, cardiopulmonary performance, genetics, healthcare consumption and health outcome data. ActiveLIFE will allow to further refine, extend and personalize future guidelines on PA and SB for optimal PA prescription. Ethics & dissemination: Ethics approval for the Lifelines Biobank, including the ActiveLIFE add-on study, was obtained from the Medical Ethics Committee of the University Medical Centre Groningen, the Netherlands (#2007/152). Informed consent was obtained from all participants. Study findings will be disseminated through peer-reviewed publications and conference presentations, and societal outreach approaches.

Background: Omega-3 polyunsaturated fatty acids may modulate lipid-mediated inflammatory pathways implicated in migraine, yet pediatric trial methodologies evaluating biologic target engagement remain limited. This study evaluated the feasibility of conducting a pediatric nutrition-based migraine intervention trial integrating longitudinal dried blood spot biomarker collection, validated patient-reported outcome measures, dietary assessment, and caregiver-reported acceptability measures. Methods: A quasi-randomized, double-blind, placebo-controlled feasibility trial was conducted at two academic pediatric neurology clinics. Children and adolescents aged 10-17 years with migraine were assigned 1:1 using sequential alternating allocation to daily omega-3 supplementation (850 mg eicosapentaenoic acid + docosahexaenoic acid) or matched coconut oil placebo for 12 weeks. Feasibility outcomes included recruitment yield, participant retention, caregiver-reported supplement adherence, dried blood spot biospecimen completion, 24-hour dietary recall completion, and intervention acceptability assessed via caregiver exit questionnaire. Feasibility benchmarks were established post hoc based on published pediatric trial literature: recruitment >70% of target sample, retention [&ge;]70%, supplement adherence [&ge;]70% of caregivers reporting administration on most days, biospecimen completion [&ge;]90%, dietary recall completion [&ge;]80%, and acceptability rated favorably by [&ge;]70% of caregivers. Clinical efficacy outcomes will be reported separately. Results: Of 58 individuals assessed for eligibility, 57 were enrolled and allocated (29 intervention, 28 placebo). Forty-four participants (77%) completed the 12-week follow-up (22 per group), meeting the retention benchmark. Dried blood spot collection was completed at both time points for all participants who attended study visits (100%). All 44 study completers finished all four planned dietary recalls (100% completion). Caregiver-reported acceptability was high, with the majority rating daily supplement administration as acceptable and reporting openness to future dietary supplement use for migraine management. Thirteen participants discontinued: five withdrew, five were lost to follow-up, two discontinued due to supplement palatability, and one no longer met inclusion criteria. Structured telephone follow-up at weeks 4 and 8 supported retention and adherence monitoring. Conclusions: This feasibility trial demonstrated that a pediatric nutrition-based migraine intervention integrating dried blood spot biomarker collection, repeated dietary recalls, validated patient-reported outcomes, and structured remote follow-up is feasible and acceptable to families. All six post-hoc feasibility benchmarks were met. Findings support progression to a larger-scale randomized controlled trial with modifications including concealed randomization, prospective daily headache diaries, and longer intervention duration. Trial registration: ClinicalTrials.gov, NCT06899074. Registered 20 March 2025.

Introduction: Multidomain lifestyle interventions may slow down cognitive decline and dementia, but the brain mechanisms underlying these effects remain unclear. We investigated brain, inflammation, cardiometabolic, and gut health changes associated with a six-month multidomain lifestyle intervention in Dutch older adults at risk for cognitive decline and dementia. Method: Participants aged 60-75 years with [&ge;]2 lifestyle-modifiable cardiovascular risk factors (e.g., BMI [&ge;]25, physical inactivity) were recruited and randomised in a 1:1 ratio to a high-intensity intervention or active control group using stratified (2,4) block-randomisation. The multidomain lifestyle intervention included five lifestyle domains (diet, physical activity, stress management and mindfulness, cognitive training, and sleep). Primary outcomes were changes in cerebral perfusion levels, brain activity during working memory, working memory performance, inflammation profile, and microbiota diversity. Secondary outcomes included lifestyle factors and markers of neuroimaging, brain health, cardiovascular and gut health, and cognitive functioning. The effects of the lifestyle intervention were investigated using linear mixed-effect models. Results: A total of 102 participants were randomised into the intervention (n=53) or active control group (n=49), of which 86 participants completed the six-month multidomain lifestyle intervention. Baseline characteristics were similar between the groups. Within the intervention group, favourable reductions in lifestyle-modifiable cardiovascular risk factors, such as BMI and blood pressure, were observed, but these were not significantly different from changes in the active control group. The intervention resulted in improved diet and sleep scores in the intervention group compared to the active control group (Beta 1.67, 95% CI 0.61;2.73, PFDR=0.01, and Beta -1.80, 95% CI -2.79;-0.81, PFDR=0.005, respectively). The intervention did not result in significant changes over time between the intervention and control group in primary and secondary outcomes. Conclusion: The HELI multidomain lifestyle was able to reduce lifestyle-modifiable cardiovascular risk factors associated with dementia, although not significant compared to the active control group. We did not observe significant intervention effects on brain, cardiometabolic, inflammatory, and gut health outcomes. These results emphasize the complexity of exploring the role of lifestyle on neurobiological brain mechanisms associated with maintaining optimal cognitive functioning in aging and their underlying peripheral (to central) mechanisms.

Abstract Background To estimate the frequency of likely, often undiagnosed autism and attention deficit hyperactivity disorder (ADHD) in UK adults of working age (18-66 years) who are not in education, employment, or training (NEET), and to examine whether neurodivergent traits are associated with NEET status directly and indirectly via health burden and educational attainment. Design Frequency-matched online case-control study. Setting UK general population, recruited via online research platform Prolific. Participants Six hundred adults of working age (18-66 years); 300 NEET, 300 in education, employment, or training (EET) matched at the marginal level on age, sex assigned at birth, and ethnicity. Primary and secondary outcome measures Autistic traits (Ritvo Autism and Asperger Diagnostic Scale-14, RAADS 14) and ADHD traits (Adult ADHD Self Report Scale, ASRS 5) indexed likely autism and ADHD (cut off [&ge;]14 on each). Physical and mental health conditions were self reported and aggregated into composite indices of health burden. NEET status was the primary outcome; educational attainment and health burden were tested as parallel mediators of the association between neurodivergent traits and NEET status. Results NEET participants screened positive more frequently for likely autism (66.3% vs 49.0%; OR 2.05, 95% CI 1.48 to 2.85) and likely ADHD (34.3% vs 26.0%; OR 1.46, 95% CI 1.03 to 2.08) than EET participants, despite identical existing formal diagnosis rates. Physical (OR 2.00, 95% CI 1.38 to 2.90) and mental (OR 2.57, 95% CI 1.80 to 3.68) health conditions were also associated with higher odds of NEET status. In mediation analyses, neurodivergent traits predicted NEET status both directly (OR 1.33, 95% CI 1.13 to 1.68) and indirectly via greater health burden (indirect OR 1.13, 95% CI 1.02 to 1.35) and lower educational attainment (indirect OR 1.08, 95% CI 1.03 to 1.15). Conclusion NEET adults showed a marked excess of autism and ADHD traits, alongside elevated physical and mental health burden and lower educational attainment. Earlier recognition of neurodivergent traits, proactive provision of equitable requirements in education and employment, and integrated physical and mental health support may reduce NEET risk in this population. This has considerable implications for policy and practice in health, education, and wider society.

Background Short-term weather conditions can trigger paediatric hospital admissions, but evidence remains limited on the health relevance of intraday temperature variability, humidity, and precipitation, and generally on which subgroups are most susceptible. Methods We conducted a nationwide case time-series study of Swedish children and adolescents aged 6-18 years using linked register data. Associations between daily mean temperature, intraday temperature variability, relative humidity, and precipitation and inpatient hospitalisations were estimated with Poisson regression (individual fixed effects) combined with distributed lag non-linear models over lags 0-21 days. Outcomes included all-cause hospitalisation and cause-specific admissions. Effect modification was examined by sex, age group, socioeconomic indicators, region, and calendar periods. Findings Among 4,638,247 children and adolescents in the cohort, 1,070,702 (23.1%) experienced at least one inpatient hospitalisation, contributing 1,736,169 hospitalisation events. All-cause hospitalisation increased with higher mean temperature, with risk highest at hot extremes. Intraday temperature variability showed a U-shaped association, with higher rates at both lowest and highest exposure levels. Relative humidity showed no association with hospitalisation risk. Higher precipitation was associated with increased hospitalisation risk, but estimates at high rainfall levels were imprecise. Stratified analyses indicated modest differences by sex and socioeconomic indicators, but clearer heterogeneity by age and region, with the highest risks among younger children and in East Sweden; associations varied across calendar periods and were imprecise for most cause-specific outcomes. Sensitivity analyses mostly showed that the main curve shapes were robust. Interpretation Short-term exposure to hot temperatures, both low and high intraday temperature variability, and higher levels of precipitation were associated with an increased risk of all-cause hospitalisation among children in Sweden, with clearer variation by age group and region than by sex or socioeconomic position. These findings support targeting paediatric climate-health preparedness and early-warning systems toward younger children and higher-risk regions such as eastern Sweden and extending such systems beyond mean temperature to include intraday temperature variability, a distinct, currently overlooked driver of risk that heat-focused systems are not designed to capture.

Objectives: Healthcare data can reveal actionable opportunities to prevent asthma hospitalizations. Limited national-level data exist regarding social determinants of health (SDOH) and asthma hospitalizations. We examined SDOH-related International Classification of Diseases, Tenth Revision (ICD-10) Z-codes in national administrative data on asthma hospitalizations and described patient- and hospital-level characteristics associated with documented SDOH Z-codes. Methods: Pooled cross-sectional analysis of 2016-2022 Nationwide Inpatient Sample for 200,452 U.S. hospitalizations (all ages) with a primary diagnosis of asthma. Presence of SDOH Z-codes (codes Z55-Z65) assessed by descriptive statistics and multivariable logistic regression to calculate odds ratios (ORs) and 95% confidence intervals (95% CIs) for associations between SDOH Z-codes and patient- and hospital-level characteristics. Results: In unweighted analyses, 3,149 asthma hospitalizations had SDOH Z-codes (1.57%). The most common SDOH Z-codes were homelessness (Z59.0; n=942) and unemployment (Z56.0; n=349). Weighted chi-square analyses found all selected variables were associated with asthma hospitalization SDOH Z-code documentation. Logistic regression results varied; adjusted odds for SDOH Z-code documentation were higher for asthma hospitalizations involving male patients (aOR=1.51; 95% CI, 1.39-1.63; P < .001) compared to female patients. Asthma hospitalizations involving rural hospitals had lower odds of SDOH Z-codes documentation (aOR=0.57; 95% CI, 0.47-0.70; P < .001) compared to urban teaching hospitals. Conclusions: National 2016-2022 data indicate housing- and employment-related Z-codes were the most commonly documented SDOH within asthma hospitalizations. Future analyses could consider establishing causality and exploring how relationships between these SDOH may be used by public health practitioners and others to improve program interventions.

Objective: to estimate reconsultation risk and trajectories after a new episode of musculoskeletal pain in children and young people (CYP), and to determine routinely recorded prognostic factors associated with reconsultation. Design: Population based retrospective cohort study. Setting: Clinical Practice Research Datalink (CPRD) Aurum, 2005-2021. Participants: CYP aged 8-18 years consulting primary care for a new musculoskeletal pain episode (no musculoskeletal consultation in prior 12-months). Main Outcome Measures: Musculoskeletal pain reconsultation within 12-months, and 3-year musculoskeletal reconsultation trajectories derived using latent class growth analysis. Prognostic factors selected from a literature search and two-year symptom histories (sample prevalence >1%) were examined using regression models (conditional logistic; multinomial). Results: Among 313,830 CYP with >12 months' follow-up, 32% reconsulted for musculoskeletal pain within 12 months. Among 240,384 CYP with >3 years' follow-up, three trajectories were observed: single episode (62%), early reconsultation (18%), and persistent reconsultation (20%). Older age; female gender; hip, knee, multisite and back pain on index; previous headache; previous abdominal pain; and analgesic prescribing were associated with higher reconsultation risk. Asian or Black ethnicity, and residing in more deprived areas, were associated with lower recorded reconsultation. Conclusion: Most CYP had no further recorded consultation, but 38% followed early or persistent reconsultation trajectories. Routinely recorded prognostic factors, particularly index pain side and prior pain/symptom history, may differentiate groups who could benefit from proactive follow-up. Lower recorded reconsultation among Asian and Black individuals, and living in more deprived areas, should not imply lower need and warrants equity-sensitive monitoring of access, health-seeking, and coding.

Background: Physical inactivity remains a major public health challenge, and policy action across sectors is needed to create environments that enable active lifestyles. Several tools have been developed to evaluate national physical activity policies, but it remains unclear whether they assess similar policy aspects or produce comparable results. This study compared evaluation results across the 27 EU member states and examined the indicators used by these tools. Methods: Eight physical activity policy evaluation tools were included that (a) assess national physical activity policies and (b) had been applied in multiple countries. For five tools covering at least half of the EU member states, aggregate scores were extracted or calculated and converted into country rankings. A total of 202 indicators were coded and mapped by category (policy content, process, structure), and data type (audit, content, implementation, impact assessment). Results: Country rankings varied considerably, with a mean difference of 13.0 positions between highest and lowest ranks. Some countries displayed consistent results (e.g., Austria, France, Germany), while others showed large discrepancies (e.g., Hungary, Spain). Indicator mapping revealed a focus on policy content (47.6%), followed by structure (21.6%) and process (13.7%) (6.2% other). Across tools, 20.3% of indicators audited policies, 26.0% assessed policy content, and 26.4% assessed policy implementation (16.3% other). Conclusion: The systematic comparison of indicators across physical activity policy evaluation tools provided insights into differences in country rankings. Future evaluations should clearly communicate their purpose, identify synergies between tools, address gaps in policy evaluation, and strengthen the reproducibility of evaluation processes.

Background: Rising rates of young people Not in Education, Employment, or Training (NEET) in the UK have recently coincided with declining youth physical and mental health but no study has asked whether this reflects a growing proportion of young people with health problems (prevalence) or those with health problems becoming more likely to be NEET (penalty). Methods: Using 15 years of Understanding Society data (2009-23), we analysed 15,242 respondents aged 16-24 (66,160 observations). We employed three complementary approaches: descriptive trends, Blinder-Oaxaca-Kitagawa (BO) probit decomposition comparing 2009-2013 and 2019-2023 against a 2014-2018 reference period, and fixed-effects (FE) Poisson models with lagged health status. Exposures included self-reported health conditions or disability (SRHD), psychological distress , diagnosed conditions and socio-demographic factors. Findings: NEET rates were lowest in 2014-18 (10.5-11.5%) and higher in 2009-13 (12-15%) and 2019-23 (15-16%). Higher prevalence of SRHD, psychological distress, diagnosed depression and multimorbidity explained changes in NEET prevalence across both the 2009-13 to 2014-2018 and 2014-18 to 2019-23 periods. No change in penalty was observed for any health variable across periods, except for an increase in the penalty for SRHD between the 2009-13 to 2014-18 periods. Interpretation: Rising NEET rates among UK youth are driven largely by more young people having physical and psychological ill health. Whilst labour market and education accommodations remain important, reducing NEET rates will require reversing the decline in youth health, not just accommodating it.

Depressive disorders are one of the most common psychiatric conditions worldwide. We systematically screened a prespecified exposure panel for associations with depressive symptoms and evaluated cross-wave replication among Brazilian adults. This preregistered exposure-wide association study used independent, nationally representative cross-sectional samples from the 2013 (n=60,202) and 2019 (n=88,531) Brazilian National Health Surveys. 31 general exposures were assessed with survey-weighted regression; four occupational exposures were analysed separately. The primary outcome was a positive Patient Health Questionnaire-9 screen (PHQ-9 >=10); continuous PHQ-9 score was secondary. Discoveries required a Benjamini-Yekutieli-adjusted p<0.05 in 2013; replication required the same coefficient direction and raw p<0.05 in 2019. 21 general exposures were primary discoveries, and all replicated. Associations spanned health status/health care (n=11), behaviour/participation (n=5), and social/material context (n=5). Poor or very poor vs very good self-rated health showed the largest association (adjusted prevalence ratio 10.97, 95% CI 8.79-13.69 in 2013; 12.33, 10.19-14.92 in 2019). Replicated correlates also included morbidity, smoking, prolonged television viewing, diet, group activities, education, income, sanitation, and nearby public space. All 25 continuous-outcome discoveries replicated. All four occupational associations retained the same direction and raw p<0.05 in 2019. This recurrent profile provides a reproducible map for prioritizing longitudinal research but, because both waves were cross-sectional and exposures were modelled separately, does not establish temporality, causality, or independent effects.

Background: High rates of young people who are not in education, employment or training (NEET) are a major societal concern in the UK. Whilst other studies have highlighted that adolescent health can predict NEET status in young adulthood, robust and recent longitudinal evidence remains limited. Methods: This study used data from the Millennium Cohort Study, a longitudinal study of people born in the UK in the early 2000s, to estimate the extent to which mental health conditions, physical health conditions and health behaviours during adolescence predict NEET status in early adulthood (median age: 23). Co-occurrence of exposures was also considered and population attributable fractions were calculated to account for differences in exposure prevalence. Results: Among 8,374 young people, 12.5% were NEET at age 23; approximately two thirds were seeking work and one third were economically inactive. Estimates adjusted for demographic factors indicated that multiple health exposures increased risk of being NEET at age 23, with mental health conditions predicting greater risk than physical health conditions and health behaviours. For instance, a longstanding mental health condition more than doubled the risk of being NEET (adjusted relative risk [aRR] = 2.39, 95% CIs = 1.85, 3.09), while autism (aRR = 3.60, 95% CIs = 2.69, 4.83) and ADHD (aRR = 3.25, 95% CIs = 2.38, 4.44) more than tripled the risk. A greater number of reported adolescent mental health conditions was associated with greater risk of being NEET in young adulthood. Obesity predicted being NEET at age 23 (aRR = 1.54, 95% CIs = 1.18, 2.01) and obesity accompanied by a mental health condition further increased risk (aRR = 2.01, 95% CIs = 1.38, 2.93). Follow-up analyses indicated that associations between adolescent mental health and young adult NEET status were more pronounced for females than males and for the economically inactive than those seeking work. Conclusions: Findings indicate that adolescent health, especially mental health, strongly predicts being NEET in early adulthood. Early, integrated health and education interventions may help reduce later educational and labour market disengagement.

Background Sepsis is a life-threatening medical condition caused by the bodys extreme response to an infection. It can have lasting physical, cognitive, psychological and social consequences that extend beyond the acute illness. However, limited research has explored how people with a history of sepsis and their families experience these longer-term consequences and engage with healthcare services in Ireland. Methods A qualitative study was conducted using semi-structured interviews with 21 participants, including 14 people who had personally experienced sepsis and seven family members of people affected by sepsis. Participants were recruited through professional networks and a sepsis charity organisation in Ireland. Interviews were conducted by telephone or Zoom between May and June 2026, audio-recorded and transcribed verbatim. Data were analysed using Braun and Clarke's reflexive thematic analysis. Results Five themes were identified: (1) recovery - a prolonged journey of physical & cognitive rebuilding; (2) navigating a recovery journey: lack co-ordination and integration; (3) continuity of support was uneven and often depended on individual healthcare professionals; (4) recovery reshaped family roles, work and everyday life; and (5) participants suggested a more coordinated approach to recovery. Participants described persistent physical, cognitive and psychological difficulties, alongside substantial effects on family responsibilities, employment and everyday activities. While some participants experienced valuable support from individual healthcare professionals, many described fragmented services, limited information about recovery and uncertainty about where to seek ongoing support. Conclusion Individuals with a history of sepsis and their families described substantial and ongoing consequences and variable experiences of longer-term care. The findings highlight the need to better recognise and respond to longer-term health needs following sepsis and to develop coordinated, accessible approaches to ongoing support in Ireland.

BACKGROUND: Undernutrition is the leading risk factor for tuberculosis (TB), yet evidence on programmatic nutritional support during treatment is limited. Benin and Togo are neighboring West African counties. Benin provides in-kind food support to all people with drug-susceptible TB; neighbouring Togo does not. This created the opportunity for a natural experiment. METHODS: We conducted a prospective cohort study at 13 sites in Benin and Togo (September 2023-June 2024). We compared recipients of nutritional support with non-recipients, using Beninese non-recipients as an internal comparison. Primary outcomes were [&ge;]5% weight gain at month 2, change in 6-minute walk test (6MWT) distance, and pill-count adherence. We used multivariable regression adjusted for pre-specified covariates. RESULTS: Of 769 participants, 450 received nutritional support and 319 did not. Recipients had higher odds of [&ge;]5% weight gain at month 2 (adjusted odds ratio [aOR] 1.57, 95% CI 1.13-2.19) and [&ge;]10% at month 6 (aOR 1.92, 1.35-2.74), greater 6MWT improvement (adjusted {beta} 40.6 m, 26.5-54.6), and higher adherence (aOR 3.43, 1.81-6.51). Mortality was lower among recipients (aOR 0.32, 0.11-0.93). Sputum conversion and treatment success did not differ. Beninese non-recipients resembled Togolese participants across outcomes. CONCLUSION: Programmatic nutritional support was associated with improved weight gain, functional recovery, adherence, and lower mortality during TB treatment, supporting its integration into national TB programmes.

This study aimed to examine factors associated with behavioural difficulties among school-aged children (aged 7 -11) using self-reported survey data linked with education data from a national cohort study of over 50,000 children (the HAPPEN national cohort) in Wales, UK between 2014 and 2024. Data include self-reported health and wellbeing linked to additional learning needs (ALN) status collected from education data in Wales. Measures included self-reported time spent on screens, frequency of sugary snack, fizzy drink and takeaway food consumption, physical activity levels, sleep duration and behavioural difficulties (as measured by the Me and My Feelings Survey). Associations were analysed using descriptive trends, K-means cluster analysis and multivariate regression modelling. Findings showed a rise in behavioural difficulties during and post Covid, which are now improving in Wales. Cluster analysis identified that children with poor sleep and high takeaway and fizzy drinks dietary habits had the highest levels of behavioural difficulties, a trend that remained significant after adjusting for all potential confounders. Physical activity associated with reduced behavioural difficulty, with 5-6 days of activity associated with the lowest difficulty scores. These findings suggest that behavioural difficulty is driven by health behaviours especially sleep and diet rather than single factors. The results highlight the need for integrated public health approaches that address dietary quality and sleep hygiene rather than focusing on single factors in isolation. Promoting more balanced daily activity patterns, promoting good sleep routines, improving food environments and building movement into the school day may have important benefits for childrens behaviour.

Background: Valid and feasible measures of preschoolers' 24-hour movement behaviours are needed for population-level research. We developed a Japanese version of the Movement Behaviour Questionnaire-Child (MBQ-C) and evaluated its measurement properties and practicality. Methods: After translation and cross-cultural adaptation following the COSMIN procedure, including cognitive interviews, we evaluated the questionnaire in a cross-sectional validation study of Japanese children aged 3-6 years. Concurrent validity was assessed against hip-worn accelerometry and a 7-day diary; we also examined test-retest reliability, measurement error, agreement between response formats and modes, and practicality (completion time, burden, and clarity). Analyses used Spearman correlations, intraclass correlation coefficients, the SEM, smallest detectable change (SDC), and Wilcoxon signed-rank tests. Results: Of 208 children, 170 provided valid accelerometer and diary data for the concurrent-validity analysis, and 187 completed the MBQ-C for the questionnaire-based analyses. Concurrent validity was weak for active and energetic play (Spearman {rho} = 0.12-0.26), strong for total screen time (0.78-0.85), and moderate for total sleep (0.48-0.58). Test-retest reliability was moderate to good (ICC, 0.66-0.81), and within-child variability was lowest for sleep (CV 3%) and highest for the physical activity items (21-33%). The open- and closed-ended versions showed no significant differences; paper-electronic agreement was good for screen time and sleep but poor for active play. Completion took approximately 6-9 minutes, with low reported burden. Findings were robust in sensitivity analyses. At the group level, SDC for a mean was SDCind/{surd}N: 119.8/{surd}N, 74.0/{surd}N, 112.6/{surd}N, and 92.5/{surd}N min/day for active play, energetic play, total screen time, and total sleep, respectively (N = number of children surveyed). The systematic differences between the two test-retest occasions were +15.7, +6.5, +4.0, and -5.4 min/day, respectively. Conclusions: The Japanese MBQ-C is a practical option for assessing preschoolers' active play, screen time, and sleep at the group level. By quantifying its group-level measurement error, this study provides benchmarks for interpreting group-level differences and change, supporting the use of the MBQ-C in surveillance and evaluation of programmes delivered at scale.
