Objective: Overweight and obesity in childhood and adolescence are major risk factors for health problems across the lifespan. This manuscript reports the current prevalence of overweight and obesity among children and adolescents aged 4-17years living in Germany and compares them with previous population-based results. Methods: A representative, cross-sectional sample of 4-17-year-olds was drawn following a multistage sampling process. Analyses are based on weight and height of 3,978 individuals measured in the field by trained test instructors between 2023-2025. Overweight and obesity classification was defined using age- and sex-specific body-mass-index percentiles. To allow for comparability of prevalence estimates derived from previous assessment waves and other panel studies dating back to 2005, an alignment factor was derived using an inverse probability of participation weighting approach. Together with sampling weights, the alignment factor was applied to obtain current, representative prevalence estimates of overweight and obesity. Results: The aligned, weighted prevalence of overweight and obesity was 16.1% (95%CI[14.5-17.9%]), whereas prevalence of obesity was 6.7% (95%CI [5.5-8.1%]). Age- and sex-specific prevalence rates are reported and compared to previous waves. Conclusions: The current prevalence of overweight and obesity in children and adolescents aged 4-17 years living in Germany remains stable over the past two decades.

Background Type 2 diabetes (T2D) disproportionately affects socioeconomically disadvantaged communities. Evidence on the feasibility and effectiveness of prevention and self-management strategies in complex contexts remains limited. Objective To report effectiveness outcomes from a feasibility trial comparing the SMART2D intervention with routine primary care for T2D prevention and control in two neighbourhoods in Stockholm. Methods A cluster-randomized feasibility trial with hybrid type 1 design was conducted in two neighbourhoods among individuals at high risk of T2D (n=84) or with diagnosed T2D (n=58), allocated to an integrated care arm (n=70; personal coaching and community outreach) or facility-only arm (n=72; routine care). Primary outcomes were glycaemic control (participants with T2D) and HbA1c reduction (participants at high risk of T2D); secondary outcomes were retention to care and diabetes incidence (participants at high risk of T2D). Analysis used intention-to-treat principles: difference-in-differences with mixed-effects models for HbA1c reduction, and modified Poisson regression (IRR, 95% CI) for other outcomes. Results Among participants with T2D, glycaemic control (adjusted IRR=0.92, 95% CI=0.89-0.95) and retention to care (adjusted IRR=0.91, 95% CI=0.91-0.92) were significantly lower in the integrated care arm. Among participants at high risk of T2D, integrated care showed a marginally significant, greater HbA1c reduction (adjusted 2.02, 0.20-3.84) and significantly higher retention to care (adjusted IRR=1.22, 1.15-1.29), plus fewer incident diabetes cases (0 vs. 2 in facility-only). Conclusions Integrated care (personal coaching, community outreach) benefited HbA1c reduction and retention among participants at high risk of T2D, whereas facility-only care improved glycaemic control and retention among participants with T2D.

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. Fundings This research was funded by Formas the Swedish Research Council for Sustainable Development (grant no. 2023-01774 and 2022-01845) and the Swedish Research Council (2025-02804 and 2022-06599).

Social media influencers serve as a key source of health information for adolescents but often lack expertise, have commercial motives, and may spread misleading or harmful content. This study examines the health-related content shared by influencers, the prevalence of advertising, and how adolescents evaluate potential benefits and risks. Using a mixed-methods approach, we employed a quantitative descriptive method involving citizen science (Study 1) and a qualitative content analysis (Study 2). In Study 1, 336 adolescents from 16 Austrian schools documented and categorized 2,147 posts from 255 influencers. The most common topics included sports and fitness (50.5%), beauty ideals (29.6%), food and nutrition (27.6%), and cooking (19.1%). Although advertisements appeared in 41.5% of posts, adolescents rated 60.4% of them as beneficial and only 4.5% as harmful. The qualitative analysis of a subsample of the 90 most prominent posts showed that adolescents appreciated motivational aspects (e.g., healthy eating) but often overlooked problematic elements such as misleading claims, sexualized body ideals, and the linking of health messages to commercial products. Enhancing persuasion knowledge and critical thinking through education, along with stricter regulation of harmful products, is crucial to safeguarding youth online.

Background: Previous studies indicated that regional fluctuations in COVID-19 impact were associated with socioeconomic, demographic and environmental factors early in the pandemic. It is unclear whether factors associated with regional COVID-19 mortality and SARS-CoV-2 infections changed over the course of the pandemic. Methods: We evaluated the association of ecological factors with municipality-specific COVID-19 mortality in the national population of Austria between January 2020 and June 2023. Analyses were conducted separately per calendar year and pooled across years via random-effects meta-analysis. Outcomes were analysed using univariable and multivariable zero-inflated negative binomial (ZINB) regression, including annually averaged environmental exposome exposure (including air pollution and UV radiation), socioeconomic, demographic and infection dissemination predictors with significance threshold set to p<0.005. Secondary analysis modelled SARS-CoV-2 infections using of negative-binomial model (NB). Two additional approaches for smaller predictor set selection were applied as sensitivity analyses. Results: Within the entire observation period 18,430 COVID-19 deaths were reported. In univariable analyses (pooled RR (99.5% CI)), COVID-19 mortality was significantly associated with the proportion of commuters (0.79 (0.73-0.86)), residents aged 75-84 (1.18 (1.01-1.37)) and [&ge;]85 years (1.29 (1.04-1.60)), residents with at most compulsory education (1.15 (1.02-1.29)), employed residents aged 15-64 (0.89 (0.85-0.93)), and homeowners (0.91 (0.83-0.99)), as well as with precipitation (0.94 (0.89-0.99)) and the average time with a mean temperature of 5-15 C (0.95 (0.90-0.99)). In multivariable analyses the share of population aged 85 or older (1.30 (1.09-1.54)) and home ownership (0.92 (0.87-0.98)) were independently significant. Mortality predictor estimates were relatively stable across pandemic years. Across 5,963,882 documented SARS-CoV-2 infections share of employed in 15- to 64-year-olds (1.01 (1.01-1.02)), part-time employment rate (1.01 (1.00-1.02)) and district level nursing care allowance recipiency (0.97 (0.95-0.98)) were associated with detected infections. Overnight stays, population 85 or older, income, compulsory education or less and air pollution all had multiple significant estimates with opposite directionality, leading to non-significant overall associations. Sensitivity analyses outcomes mirrored main analyses outcomes. Conclusions: Throughout the pandemic in Austria, demographic and socioeconomic factors were associated with COVID-19 mortality and infections, but many associations, especially for infections, were unstable over time. These findings underscore the importance of structural vulnerabilities in epidemic impact.

Background: Women are recommended to take folic acid supplements (FAS) periconceptionally to prevent neural tube defects, but the low levels of FAS uptake are poorly understood. This study aimed to determine how parity, pregnancy planning and other maternal factors affect the timing of FAS initiation. Method: We used data from a representative sample of 966 pregnant women from the Northern Ireland Baby Hearts study. Questionnaire responses on health behaviours, including FAS, were linked to maternity and area-based deprivation data. Logistic regression assessed determinants of FAS initiation preconception. Time-varying Cox regression assessed associations between initiation postconception and pregnancy-related milestones. Results: Forty-one per cent of women initiated FAS preconception. Lower odds of preconception initiation were associated with multiparity (adjusted OR 0.47 (0.32 to 0.68)), unplanned pregnancy (adjusted OR 0.08 (0.05 to 0.13)), deprivation and consuming a low folate diet. Higher odds were associated with fertility treatment and previous pregnancy loss. Forty-seven per cent of women initiated FAS postconception, mainly after pregnancy recognition (median 5 weeks), including 34.1% of those who planned their pregnancy. For primiparous women with unplanned pregnancies, the first health service contact (median 7 weeks) further increased FAS initiation. Conclusion: Many women, even multiparous women with previous pregnancy experience and women who planned their pregnancies, are initiating FAS after pregnancy recognition. This shows awareness of FAS benefits, but is too late to prevent neural tube defects. Public health interventions need to go beyond awareness to address motivation and opportunity for FAS, and pay more attention to multiparous women.

Background: Built environment characteristics have been associated with depressive symptoms, whilst active travel behaviour is linked to improved mental health. However, it remains unclear whether active travel buffers associations between increased exposure to the built environment and worse mental health. Methods: In this pre-registered study, participants were 10,310 mothers (mean age = 28.11, SD = 4.83) participating in the Avon Longitudinal Study of Parents and Children (ALSPAC). A latent built environment factor was measured at study enrolment, active travel behaviour at a 2-year follow-up, and depressive symptoms at a 4-year follow-up. Moderation was examined using adjusted linear regression models including an interaction term between the built environment factor and active travel behaviour. Results: The built environment factor was positively associated with depressive symptoms ({beta} = 0.023, p = .012). Active travel behaviour was not associated with depressive symptoms ({beta} = -0.002, p = .854) and did not moderate the association between the built environment factor and depressive symptoms ({beta} = -0.002, p = .865), after adjusting for covariates, including age, familial depressive history, socioeconomic risk factors, physical activity, baseline depressive symptoms and smoking. Conclusion: Contrary to expectations, active travel behaviour does not modify associations between the built environment and depressive symptoms. These findings provide no evidence that active travel mitigates mental health risks associated with the built environment in this population.

Background/Aims This work aimed to estimate the annual tertiary healthcare and societal costs associated with paediatric congenital heart disease (CHD) in the United Kingdom using real-world data from a Level 1 cardiac surgical centre in the National Health Service (NHS). Methods A prevalence-based cost-of-illness analysis was conducted using patient-level inpatient and outpatient activity data from Evelina London Children's Hospital between 1 June 2023 and 31 May 2024. Costs were estimated from NHS and societal perspectives and extrapolated to national level using National Congenital Heart Disease Audit (NCHDA) procedural activity data. Healthcare costs included tertiary centre care costs. Societal costs included parental productivity losses and impacts on lifetime earnings for children. Deterministic sensitivity analysis explored parameter uncertainty. Results Approximately 9.6% of UK paediatric CHD procedures were undertaken at Evelina London Children's Hospital at a cost of {pound}15.0 million per annum, corresponding to a national estimate of {pound}156.4 million. Single-ventricle procedures accounted for 4.8% of inpatient activity but 19.4% of inpatient costs. Sensitivity analysis produced national healthcare cost estimates ranging from {pound}125.1 million to {pound}187.7 million. National productivity losses associated with parental absence from work were estimated at {pound}82.4 million annually. Individuals with CHD were estimated to experience a mean reduction in lifetime earnings of {pound}81,509. Conclusion Paediatric CHD imposes a substantial economic cost on the UK healthcare system and wider society. This study provides the first real-world national estimate of the economic impact of paediatric CHD in the UK and may inform future service planning, research investment, and innovation adoption strategies.

Objectives. To evaluate the impact of reimbursement restrictions for glucagon-like peptide-1 receptor agonists (GLP-1RAs) for type 2 diabetes, introduced in Denmark in November 2024, on injectable semaglutide (Ozempic) utilization patterns and subsequent HbA1c changes among discontinuers. Design. Nationwide registry-based cohort study. Setting. Denmark. Participants. Adults treated with injectable semaglutide for diabetes (January 2018 to December 2025). Main outcome measures. We described temporal patterns in injectable semaglutide use before and after the policy change. Among semaglutide continuers after the policy change, we assessed whether continuation met a key criterion in the new policy: non-feasibility of sodium-glucose cotransporter 2 inhibitor use and high cardiovascular risk. We characterized semaglutide discontinuers around the policy implementation (March 2024 to November 2024) and subsequent treatment switches. Among discontinuers, we evaluated HbA1c changes and performed interrupted time series (ITS) analyses. Results. Following the policy change, use of injectable semaglutide declined modestly before subsequently increasing. Among 61,120 individuals classified as semaglutide continuers, 27,143 (44%) were already using an SGLT2i. Of the remaining 33,977 (56%), only 1,862 (5.5%) met a key reimbursement criterion (i.e., non-feasibility of SGLT2i use and high cardiovascular risk). Among 79,305 individuals with a semaglutide fill between March 2024 and November 2024, 22,096 (28%) were classified as discontinuers. Within six months, ~40% of discontinuers switched to other glucose-lowering therapies, most commonly SGLT2is (24%). 37% of discontinuers later reinitiated semaglutide. Among individuals with an on-treatment HbA1c measurement (within 12 months before their last semaglutide fill) and an off-treatment HbA1c measurement (6-12 months after their last semaglutide fill) (n=13,017), mean HbA1c increased from 49 to 57 mmol/mol (mean change +7.4 mmol/mol, 95% CI 7.2-7.6). ITS analysis showed that HbA1c increased by 5.9 mmol/mol (95% CI 5.1-6.7) at six months post-discontinuation, which attenuated to 3.1 mmol/mol (95% CI 2.2-4.1) at 12 months; raw monthly means (not included in the ITS model) suggested this persisted through 18 months. Conclusions. Following the policy change, population-level use of injectable semaglutide declined modestly before increasing again. Most discontinuers did not initiate another glucose-lowering therapy and experienced an increase in HbA1c that did not fully return to pre-discontinuation levels during follow-up.

Disability is an important population-health concern, but adult-specific evidence on its distribution and socioeconomic patterning remains limited in Somaliland. This study estimated the prevalence and distribution of reported disability among adults in Somaliland and examined socioeconomic inequality, reported mental/psychological illness, and their co-occurrence. We conducted a cross-sectional secondary analysis of the 2020 Somaliland Health and Demographic Survey. The analysis included 14,579 adults aged [&ge;]18 years who were usual residents, had the disability module administered, and had a defined reported mental/psychological illness measure. Reported disability was defined as at least one positive response across seven disability domains: sight, hearing, speech, learning, mobility, self-care, and mental. Survey-weighted prevalence estimates and design-based comparisons were calculated. Survey-weighted logistic regression assessed associations with household wealth and other covariates. Socioeconomic inequality was assessed using a concentration index and the normalized Erreygers concentration index. Co-occurrence was evaluated by comparing observed joint prevalence with that expected under statistical independence and by survey-weighted logistic regression. The survey-weighted prevalence of any reported disability was 7.30% (95% CI 6.65-8.02). Sight was the most frequently reported domain (3.83%, 95% CI 3.19-4.59), followed by hearing (1.54%, 95% CI 1.20-1.97) and mobility (1.39%, 95% CI 1.14-1.70). Disability prevalence increased markedly with age, from 4.15% among adults aged 18-29 years to 23.96% among those aged [&ge;]60 years. The crude wealth pattern was non-monotonic and was not statistically detectable after adjustment for residence and region. The concentration index for reported disability was 0.0584 (SE 0.0284, p=0.0415). Reported mental/psychological illness had a weighted prevalence of 0.71% (95% CI 0.50-1.00). Both reported disability and reported mental/psychological illness occurred in 0.5032% of adults, compared with 0.05185% expected under statistical independence; the observed-to-expected ratio was 9.70 (95% CI 7.60-11.81). After adjustment for age group and sex, reported disability was strongly associated with reported mental/psychological illness (OR 42.99, 95% CI 18.45-100.18). Reported disability affected approximately one in fourteen adults in Somaliland and showed a marked age gradient and substantial geographic variation. The crude socioeconomic pattern was attenuated after adjustment for geographic context, while concentration analysis indicated modest marginal concentration toward higher wealth ranks. Reported mental/psychological illness was uncommon but co-occurred with reported disability more often than expected under independence. These findings provide an adult population baseline for Somaliland while highlighting the need to distinguish survey-reported disability from the separate mental/psychological illness construct and to interpret the findings within the limitations of cross-sectional, survey-reported measures.

Background Oral glucose tolerance test (OGTT), the gold standard for diagnosing gestational diabetes mellitus (GDM), faces significant implementation challenges, prompting interest in alternative biomarkers, such as glycated hemoglobin (HbA1c), for early detection. This study aimed to assess the association between early pregnancy HbA1c and subsequent GDM and adverse perinatal outcomes in low- and middle-income countries. Methods We analyzed data from the Pregnancy Risk, Infant Surveillance, and Measurement Alliance - Maternal and Newborn Health (PRISMA-MNH) cohort, which followed pregnant women enrolled before 20 weeks of gestation across five study sites in Kenya, India, Pakistan, and Zambia. We excluded participants with overt diabetes, severe anemia (Hb <7.0 g/dl), multiple gestations, or pregnancies that ended before 24 weeks of gestation. HbA1c was measured at enrollment. The primary outcome was GDM, diagnosed according to the International Association of Diabetes and Pregnancy Study Groups (IADPSG) criteria based on OGTT performed after 24 weeks of gestation. Secondary outcomes included hypertensive disorder of pregnancy, emergent Cesarean section, preterm birth, large for gestational age, and stillbirth after 28 weeks. We used AUC and ROC analyses to evaluate predictive performance and single- and two-threshold approaches to identify optimal cutoffs for predicting GDM. We used modified Poisson regression with robust standard errors to assess associations between early HbA1c and outcomes, and meta-analysis to pool site-specific estimates. Results Among 10,918 pregnancies, GDM prevalence was 6.4%. Women with GDM were older (28.0 +/- 5.4 versus 26.0 +/- 5.3 years) and had higher BMI at enrollment (25.0 +/- 5.8 versus 22.9 +/- 5.0 kg/m2) than women without GDM. The AUC for HbA1c alone in predicting GDM was 0.65 (95% confidence interval 0.63-0.67). A single early HbA1c threshold of 5.4%, based on the largest Youden's index, showed limited predictive performance (sensitivity 46.7%, specificity 75.8%). A two-threshold approach identified rule-out and rule-in cutoffs of 5.0% (sensitivity 80.3%, specificity 35.6%) and 5.5% (sensitivity 34.5%, specificity 83.1%), respectively. In adjusted models, each 0.1% increase in HbA1c was associated with a 12% higher risk (RR 1.12, 95% CI 1.10-1.15) of GDM, while no significant associations were observed for any secondary outcomes. Conclusion Early pregnancy HbA1c is independently associated with an increased risk of subsequent GDM. However, it demonstrated limited discriminatory ability as a standalone alternative to OGTT for identifying women who would later develop GDM. The identified rule-out threshold may help identify women at low risk of GDM, although the majority would still require OGTT for definitive diagnosis.

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.

Background: Mounting evidence shows war directly and indirectly harms civilian health. As the largest conflict since World War II, the war in Ukraine severely impacts civilian survival. Stroke--a leading cause of death in Ukraine--represents a key population-level vulnerability to full-scale war. We assessed the war's impact on population-level stroke mortality. Methods: This retrospective cohort study evaluated patients diagnosed with hemorrhagic or ischemic stroke admitted to Ukrainian civilian hospitals from April 1, 2020, through December 31, 2024. Using data from the Ukrainian nationwide electronic health record system, we compared pre-war and post-war stroke mortality. We used multivariate proportional hazards regression with propensity matching to test if in-hospital mortality increased. Excess deaths were estimated by multiplying the pre-post mortality rate difference by the post-period population in person-days. Results: Among 577,501 total individuals, we found that the crude in-hospital stroke mortality rate increased by 117 (95% CI: 94.2-139.9) per 100,000 person-days in the post-war period. In propensity-matched analyses, the mortality risk was 5% (HR=1.05; 95% CI: 1.03-1.06; p<0.001) higher in the post-war period. Mortality risk varied by age, sex, admission type and stroke type. Patients with hemorrhagic stroke had 179% (HR=2.79; 95% CI: 2.75-2.83; p<0.001) higher risk of death compared to ischemic stroke patients. Conclusion: In the first study to assess stroke mortality at the population level in Ukraine after the start of the full-scale war, we found that in-hospital mortality increased in the post-war period with an estimated 3,944 excess stroke deaths.

OBJECTIVE: Research on neighborhood context and cognitive health often relies on composite indices that collapse neighborhood socioeconomic status (SES) and aspects of the built environment into a single score. This study examined the extent to which neighborhood SES and built environment were associated with late-life cognitive impairment. METHOD: Participants were 281 predominantly Black older adults who completed the Self-Administered Gerocognitive Exam (SAGE), a brief cognitive screening measure. Participants also provided their home address to obtain four neighborhood metrics: Two composite measures of neighborhood disadvantage, the Environmental Justice Index (EJI) and the EJI Social-Environmental Rank, as well as the EJI Social Vulnerability Rank as a measure of neighborhood SES, and the EJI Environmental Burden Rank to measure exposure to hazardous aspects of the built environment. RESULTS: Lower neighborhood SES was associated with higher odds of cognitive impairment. In contrast, greater environmental burden was associated with lower odds of impairment, with years of education as a moderator; the association was strongest among individuals with high levels of education. The two composite scores were not associated with cognitive impairment. CONCLUSION: Composite measures of neighborhood features may obscure distinct pathways of their effects on cognition.

ObjectivesTo quantify the demographic contribution to Brazils rising number of breast cancer deaths and compare mortality trends by region and race/skin color. Study designNationwide, population-based ecological time-series study. MethodsDeaths from breast cancer (ICD-10 C50) in the Brazilian Mortality Information System, 1996-2024, were analysed. Crude rates use two denominators, the whole female population and women aged 20 and over. Age-standardized rates used the 2024 IBGE projection and, by race/skin color, Census populations for 2010 and 2022. Trends used weighted log-linear regression with BIC-selected joinpoints, and deaths were decomposed by the Das Gupta method. ResultsDeaths rose from 7,085 (1996) to 20,849 (2024). Over 2000-2024 the age-standardized rate rose from 11.4 to 14.3 per 100,000 women, with one joinpoint at 2017 (average annual percent change +0.87%, 95% CI 0.77 to 0.96). Growth and ageing accounted for 74.3% of the 12,542 additional deaths at ages 20 and over. Standardized rates rose in every region, fastest in the North (+3.09%/year) and slowest in the Southeast (+0.24%/year), narrowing the highest-to- lowest ratio from 2.67 to 1.38. White women had the highest age-standardized rate at both censuses (2022: 15.96 versus 12.28 and 11.48 per 100,000), Brown women had the larger increase (ratio of relative changes 1.20, 1.13 to 1.26). ConclusionsPopulation growth and ageing accounted for most of the increase in the number of recorded breast cancer deaths at ages 20 and over. Regional differences in level narrowed, White women had the highest age-standardized rates at both censuses and Brown women the larger increase.

ObjectivesTo estimate age trajectories of infant mortality among Palestinian refugees using electronic health records, addressing the scarcity of reliable mortality data in forced displacement settings. SettingPalestinian refugees living in Gaza, West Bank, Jordan, Syria and Lebanon. DesignWe fitted a Bayesian Negative Binomial model to observed death counts, using a flexible parametric function (a shifting power function) to capture the shape of the infant mortality curve, across strata to infer age trajectories of infant mortality. ParticipantsPalestinian refugees born in 2010-2020 and registered with UNRWA health services in Gaza, West Bank, Jordan, Syria and Lebanon. The sample was stratified by sex, field, gestational age and birth cohort. Main outcome measuresSurvival rate to age 1. ResultsOverall, the survival rate to age 1 was 98.64%, with slightly lower rates for males (98.57%) than females (98.68%). Across settings, West Bank refugees had the lowest infant mortality (99.08% survival rate), and Jordan refugees had the highest (98.22% survival rate). Results by gestational age showed a 98.85% survival rate at age 1 among term births compared to a 73.32% survival rate among very preterm births. Survival rates by cohort (births up to 2015 or after) were 98.78% and 98.42%, respectively. ConclusionOur findings highlight the potential of electronic health records for mortality monitoring in forced displacement settings as they reveal consistent mortality trajectories by sex and gestational age, while identifying meaningful variation across refugee settings and subgroups. Summary boxesO_ST_ABSWhat is already known in this topicC_ST_ABSWe searched PubMed and Google Scholar for articles published between Jan 1, 2000, and Feb 20, 2026, in English, using the terms "Palestinian refugees," "infant mortality," "neonatal mortality," and "UNRWA." We found a handful of studies estimating infant mortality among Palestinian refugees, mostly based on household surveys (eg, MICS, national statistical office surveys) or UNRWA surveys using preceding birth techniques. The preceding birth technique has notable limitations, including recall bias, small sample sizes, and selection bias. The majority of these studies focus exclusively on Palestinian refugees residing in Gaza. Estimates for Gaza suggest a sustained decline, from around 127 deaths per 1,000 births in 1960 to 20.2 per 1,000 births in 2006, with a slowdown thereafter and an increase in more recent years. A combined estimate (excluding Syria) across four settings where Palestinian refugees reside measures infant mortality at 18 per 1,000 births in 2011. What this study addsThis study uses a unique data linkage bringing together UNRWAs obstetric and child health records, providing more extensive information and a larger sample size than previous studies. This is also the first study to assess the data quality of these electronic records and to estimate age trajectories of infant mortality among Palestinian refugees. We developed a statistical strategy that estimated infant mortality trajectories covering all five UNRWA fields (Gaza, Jordan, Lebanon, Syria, and the West Bank) for children born in 2010-2020, and examined differences across subpopulations by sex, field, gestational age and cohort.

Background: Social vulnerability is associated with adverse health outcomes, but existing social vulnerability indices often rely on cohort-based and self-reported data, potentially limiting their population-level applicability. Therefore, this study aimed to develop an SVI from routinely collected electronic health records (EHRs) using natural language processing (NLP) and examine its association with mortality and healthcare utilization. Method: EHR data from 193,629 individuals aged 35 to102 from the Wellbeing Services County of Central Finland between years 2010 and 2023 were used in this study. A 6 item SVI (total score 0 to 6) was developed from free-text clinical notes using deep-learning-based NLP. SVI scores were calculated at baseline and annually for individuals. Associations between baseline SVI and all cause mortality and healthcare utilization were assessed over 12-year follow-up using Cox and count models. Results: The mean baseline SVI among all participants was 0.35 (range 0 to 6). Women had higher SVI (0.39) than men (0.32, p<0.001). SVI increased with age. One unit increase in SVI was associated with a higher risk of mortality (Hazard Ratio (HR) 1.23; 95% Confidence Interval (CI) (1.21 to 1.24), a higher odds of using healthcare services (Odds Ratio (OR) = 1.20; 95% CI): 1.19 to 1.21) and a greater healthcare service use (Incidence Rate Ratio (IRR) = 1.07; 95% CI: 1.06 to 1.07). Discussion: An index capturing multiple domains of social vulnerability can be derived from EHRs using NLP. Higher SVI was associated with increased mortality and healthcare utilization. These findings support the potential of EHR data for assessing social vulnerability and related health risks.

Objective: To compare healthcare access among U.S. children with attention-deficit/hyperactivity disorder (ADHD) only, autism only, and co-occurring ADHD-autism, and to identify social inequities associated with unmet care using recent nationally representative data. Methods: We analyzed combined 2023-2024 National Survey of Childrens Health data for 13,576 children aged 3-17 years with current ADHD and/or autism. Six healthcare-access outcomes were examined: forgone healthcare, unmet mental health care, no medical home, coverage gap or inadequate insurance, unmet specialist care, and unmet care coordination. Survey-weighted modified Poisson regression estimated adjusted prevalence ratios (aPRs) and 95 percent confidence intervals (CIs). Six multiply imputed poverty measures were combined using Rubins rules. Sensitivity models additionally adjusted for functional difficulty. Results: Compared with ADHD only, co-occurring ADHD-autism was associated with higher prevalence of forgone healthcare (aPR, 1.73; 95 percent CI, 1.38-2.16), no medical home (1.11; 1.02-1.20), inadequate or discontinuous insurance (1.14; 1.03-1.28), unmet specialist care (1.49; 1.14-1.94), and unmet care coordination (1.15; 1.04-1.28). Autism only was associated with unmet mental health care (1.49; 1.13-1.97) and care coordination (1.13; 1.02-1.25). Food insufficiency, housing instability, and non-supportive neighborhood conditions were consistently associated with poorer access. After adjustment for functional difficulty, associations remained for co-occurring ADHD-autism with forgone and specialist care and for autism only with unmet mental health care. Conclusions: Healthcare access inequities differed by neurodevelopmental diagnostic group and social context. Pediatric systems should strengthen care coordination, specialty and mental health access, insurance continuity, family navigation, and responses to food and housing hardship.

Background. In people with type 2 diabetes (T2D), postprandial glucose weighs on glycaemic control, and carbohydrate counting is difficult. Patients can describe their meal but rarely quantify it. Objective. To assess (1) whether a small open large language model (LLM), fine-tuned on public data, estimates the carbohydrate content of a meal described in words, and (2) what this carbohydrate adds to the prediction of the postprandial glucose rise in two public cohorts. Methods. Step 1: the Qwen3-4B LLM was fine-tuned with QLoRA on Nutrition5k dishes and compared with an automatically matched USDA food composition table and with Qwen3-4B and Qwen3-8B used without training, on test dishes (internal control) and on 100 real meals of ShanghaiT2DM patients, whose reference carbohydrate was computed from the recorded quantities. Step 2: the maximum glucose rise between 0 and 120 minutes ({Delta}Gmax) was predicted by personalised gradient boosting (M2), compared with a spline linear regression and with the Chronos-2 foundation model, using only information available at meal start and person-level cross-validation, in ShanghaiT2DM (people with T2D recruited in two Shanghai hospitals; carbohydrate estimated by the LLM) and CGMacros (free-living adults in Santa Barbara, California; carbohydrate entered in the dataset, no text). Step 3: the model was transferred between datasets. 95% confidence intervals (CI) were obtained by cluster BCa bootstrap (2,000 resamples). Results. On the 100 real meals, the carbohydrate mean absolute error (MAE) of the fine-tuned model was 12.2 [9.9, 15.2] g, almost half that of the table (22.6 g; paired difference -10.5 [-16.8, -6.0] g) and nearly a third of that of the same model without fine-tuning (34.3 g), with a bias of -10.3 g; on test dishes it was 2.2 [2.0, 2.5] g. Personalised gradient boosting (M2) reached a correlation between predicted and observed rises of r = 0.63 [0.55, 0.69] in CGMacros (1,286 meals, 45 adults) and 0.49 [0.42, 0.54] in ShanghaiT2DM (2,339 meals, 99 people with T2D), about twice the linear reference (r = 0.32 and 0.23); for a rise above 50 mg/dL, its area under the ROC curve (AUROC) was 0.80 and 0.74, versus 0.64 and 0.68 with pre-meal glucose alone. Adding carbohydrate to pre-meal glucose changed r by 0.095 [0.068, 0.128] in CGMacros and by 0.004 [-0.010, 0.017] in ShanghaiT2DM; difference between datasets: 0.091 [0.060, 0.126]. Applied from one dataset to the other, the model lost correlation ({Delta}r = -0.11 [-0.17, -0.05] towards ShanghaiT2DM and -0.12 [-0.19, -0.04] towards CGMacros). The full "text [-&gt;] LLM [-&gt;] glucose" chain was evaluated in ShanghaiT2DM only. Conclusion. An open 4-billion-parameter LLM, fine-tuned with QLoRA on public data and usable offline, almost halves the error of carbohydrate counting for real meals described in words compared with an automatically matched table, with an underestimation of large meals. Personalised gradient boosting, based on pre-meal glucose and the person's usual response, doubles the correlation of a linear reference for predicting the glucose rise in both cohorts. Carbohydrate improved this prediction in CGMacros but not in ShanghaiT2DM; the two datasets differ in many respects, and the cause of this gap is not established.

BackgroundStructured cognitive screening in diabetes is recommended only from age 65, leaving younger adults with prolonged type 2 diabetes mellitus (T2DM) exposure unmonitored. We quantified the association of HbA1c and diabetes duration with Montreal Cognitive Assessment (MoCA) screen-positive status in adults aged [&le;] 60 years with T2DM of [&ge;] 5 years, and examined against matched controls how the MoCA cutoff (< 26, < 24, < 23) affects the group contrast in a lower-education population. MethodsCross-sectional study at a tertiary-care centre in North India: 110 adults with T2DM and 50 controls frequency-matched for age, sex, and education. Within diabetics, HbA1c and duration were modelled continuously by modified Poisson regression at each pre-specified cutoff and by Spearman correlation with MoCA total score. Prevalence ratios (PR) for diabetics versus controls at each cutoff were adjusted for age, sex, education, BMI, and hypertension. ResultsWithin diabetics, MoCA total score correlated with HbA1c ({rho} = -0.456) and duration ({rho} = -0.318; both p < 0.001). Screen-positive prevalence rose 5% per 1% HbA1c at < 26 (PR 1.05, 95% CI 1.02-1.09), 12% at < 24 (PR 1.12, 1.06-1.18), and 17% at < 23 (PR 1.17, 1.09-1.26), and 11% per year of duration at < 23 (PR 1.11, 1.06-1.17). Median education was 10 and 9 years; 76.0% of controls screened positive at < 26, and the diabetes association was cutoff-dependent: adjusted PR 1.08 (0.89-1.29) at < 26, 1.70 (1.10-2.63) at < 24, and 6.72 (2.23-20.23) at < 23, where 44.5% of diabetics versus 6.0% of controls screened positive (absolute difference 38.5 percentage points, 95% CI 25.0 to 48.7). ConclusionsIn working-age adults with long-standing T2DM, screen-positive prevalence rose continuously with HbA1c at every cutoff, a glycaemic signal independent of threshold choice. The standard < 26 cutoff flagged over three-quarters of both groups and could not triage; < 23 separated diabetics from controls. Screen-positive status is not a diagnosis; MoCA triage at a population-appropriate cutoff in this group warrants prospective validation against a neuropsychological reference standard.
