BACKGROUND: With the increasing frequency and intensity of extreme weather events due to climate change, heat waves have emerged as a significant public health threat. To date, the potential effect of extreme heat wave events, particularly when combined with air pollution, remains poorly understood for pregnancy outcomes among women undergoing assisted reproductive technology (ART). METHODS: A retrospective study included 15,198 women receiving ART and 7519 fresh embryo transfer cycles between 2020 to 2022 at the Reproductive Center of West China Second University Hospital in Chengdu, China. Heat wave, a climate change indicator for extreme temperature events, was calculated based on daily temperature during the period of 85 days prior to oocyte retrieval. All environmental exposure variables, including weather and pollution, were matched geospatially to day 0 to day 85 before oocyte retrieval. Generalized linear model (GLMM) were used to assess the association between environmental exposures and ART outcomes, with secondary analysis using interaction terms between heat waves and individual pollutants. RESULTS: Exposure to one heat wave event was positively correlated with the likelihood of becoming pregnant (+ 34.9% in univariate model and + 34.5% in multivariate model for heat wave events + 1 time) and this association was more pronounced in women under 35 years of age (+ 53.7% heat wave events + 1 time), while no statistical correlation was observed between exposure to two heat wave events and ART outcomes. Additionally, CO exhibited a significant negative association with biochemical pregnancy for women under 35 years old (-66.2% for CO + 1 mg/m), and SO exhibited a significant negative association on biochemical pregnancy rate for women older than 35 years old (-6.5% for SO + 1 μg/m). Results from the interaction model indicated that concurrent exposure to O and two heat wave events was statistical associated with clinical pregnancy (OR = 3.77). CONCLUSIONS: Findings from this study suggest that heat waves could be an important climatic indicator that reflects the impact of extreme weather on pregnancy outcomes among women receiving ART treatment. The synergy between exposure to extreme temperatures and air pollution could be further analyzed to provide deeper insight into the environmental impact on reproductive health.

OBJECTIVES: Wastewater surveillance (WWS) is a valuable public health tool for monitoring infectious diseases. Recent studies suggest its potential for monitoring opioids or other drugs. We evaluated WWS awareness and public acceptance of WWS for respiratory and vector-borne diseases and opioids in the US population. METHODS: We conducted a nationwide cross-sectional survey in June 2024 among US adults aged ≥18 years. We used quantitative analysis (N = 2024) to assess associations between participants' awareness of and attitudes toward WWS, including how those data should be used. We performed qualitative analysis to identify themes among participants who provided comments about opioids or other illicit drugs (n = 67). RESULTS: Overall, more than half of participants expressed comfort with WWS for respiratory diseases (54.1%), mosquito-borne diseases (57.3%), and opioids or other drugs (51.1%). These percentages were significantly higher ( < .001) among people with awareness of WWS than among those who were unaware of WWS: 70.6% were comfortable with WWS for respiratory diseases and 71.6% were comfortable with WWS for mosquito-borne diseases, while slightly fewer participants were comfortable with WWS for opioids or other drugs (64.8%). Among those unaware of WWS, about half were comfortable with WWS for respiratory diseases (50.8%), mosquito-borne diseases (55.5%), or opioids or other drugs (49.2%). Qualitative analysis highlighted concerns about privacy, changes in law enforcement activity with opioid monitoring, and the possibility of negative community effects. CONCLUSIONS: Comfort with WWS activities was higher among those who were aware of WWS than among those who were not. Future efforts could focus on improving public awareness and knowledge of how wastewater data are collected and used to benefit public health.

BACKGROUND: Health perception mismatch is common in older adults, yet its longitudinal patterns and prognostic value remain unclear. This study aimed to identify distinct mismatch trajectories and their associations with depression, cognitive decline, and mortality. METHODS: Data from three longitudinal ageing cohorts-the China Health and Retirement Longitudinal Study (CHARLS), English Longitudinal Study of Ageing (ELSA), and Health and Retirement Study (HRS)-were used to identify health perception mismatch trajectories and evaluate their associations with depression, cognitive impairment, and mortality. Baseline SRH-ADL/IADL interplay was examined within these longitudinal cohorts, while the National Health and Nutrition Examination Survey (NHANES) was retained as an independent external cross-sectional comparison. Associations were evaluated using multivariable regression, structural equation modeling, inverse probability of treatment weighting, causal forests, random-effects meta-analysis, and counterfactual prediction. FINDINGS: Baseline analyses in CHARLS, ELSA, and HRS showed heterogeneous and generally modest SRH-ADL/IADL additive interaction estimates, while NHANES provided an independent external cross-sectional comparison. Three stable perception mismatch trajectories, Mildly pessimistic, Mildly optimistic, and Highly optimistic, were consistently identified across CHARLS, ELSA, and HRS. Despite reporting better SRH, individuals in the Highly optimistic group had poorer baseline health and higher subsequent risks of depression, cognitive decline, and mortality. Counterfactual prediction analyses indicated 13-18% differences in mortality and depression risk between hypothetical trajectory contrasts, with the largest differences observed between the mildly pessimistic and highly optimistic classes, suggesting that discordantly favorable SRH may mark elevated risk. INTERPRETATION: Health perception mismatch trajectories may help identify older adults at elevated health risk. Discordantly optimistic perceptions may mark underlying vulnerability, suggesting that combining subjective and objective assessments could complement existing approaches to risk stratification. However, these observational findings do not establish that modifying health perceptions or trajectory membership would alter subsequent outcomes.

BACKGROUND: Hypertension is the leading risk factor for cardiovascular diseases, with the greatest burden in low- and middle-income countries where access to care and infrastructure for prevention and management is limited. In Rwanda, community health workers (CHWs) have long played a critical role in improving access to health services. In 2023, the Turambe ('Live Longer') program integrated digitally enabled hypertension screening into Rwanda's community health program across three districts, equipping CHWs with blood pressure monitors and mobile devices loaded with the mUzima mobile application. This study aimed to assess the CHW-led screening process, evaluate the screening cascade from CHW identification to diagnosis confirmation, and determine the factors associated with hypertension diagnosis. METHODS: Data was extracted and socio-demographic and clinical characteristics were analyzed using frequencies and percentages. Chi-square tests assessed associations between diagnosis and patient characteristics, and logistic regression identified factors associated with hypertension diagnosis following referral. RESULTS: The program supported the screening of 499,475 community members representing 55.9% of the population aged 15 years and above. The majority of those screened were female (54.5%) and most were aged 35-44 years (29.6%). Of those screened, 63,291 (12.7%) individuals were found to have elevated blood pressure and were referred to health facilities. Among these referrals, 4,537 (7.2%) completed the referral by visiting a health facility and 2,873 (63.3%) of them were confirmed to have hypertension; 2,218 (48.9%) were newly diagnosed and 655 (14.4%) with a prior diagnosis. Among those who completed referral to health facilities, the proportion of those confirmed to have hypertension increased with age, reaching 71.0% among individuals aged above 65 years. Multivariable analysis showed that increasing age was strongly associated with a hypertension diagnosis, with those aged ≥ 65 years having 3.91 times higher odds (aOR: 3.91; 95% CI: 2.06-7.43) compared to those aged 25-34 years. Male sex was associated with 15% reduced odds (aOR: 0.85; 95% CI: 0.75-0.98) compared to females. CONCLUSION: This digital community-based hypertension screening program achieved substantial population coverage and a relatively high diagnostic yield among those who completed referral, demonstrating the potential of leveraging CHW networks and mobile technology for large-scale NCD detection and monitoring. However, low referral-to-care linkage limits inference on CHW diagnostic accuracy at the population level. Strengthened referral systems and further research into barriers to linkage are needed to translate community screening into timely diagnosis and management.

BACKGROUND: The prevalence of type 2 diabetes mellitus (T2DM) varies significantly among Tuberculosis (TB) patients from 25.3 to 44% in India. Correct knowledge regarding TB symptoms is a determinant for health-seeking behaviour among T2DM patients. However, there is limited literature regarding TB knowledge and risk perception among patients with T2DM in rural communities of coastal Karnataka, India. OBJECTIVES: To determine the association of correct knowledge regarding TB among patients with T2DM and their TB risk perception in a rural community in coastal Karnataka. METHODOLOGY: A cross-sectional study was conducted over 18 months in the rural villages under the rural health training centre of a tertiary care private medical college at Dakshina Kannada District, Karnataka, involving 202 T2DM patients. Data were collected via pretested semi-structured questionnaires administered through interviews. Descriptive statistics and chi-square tests were used to analyse demographic variables, TB knowledge and TB risk perception. RESULTS: Among the 202 participants, 116 (57.4%) demonstrated overall correct knowledge regarding TB. Participants with high risk perception showed significantly better recognition of specific TB knowledge components, including airborne transmission (p = 0.013), key symptoms such as cough (p = 0.029), fever (p = 0.049), and weight loss (p = 0.019), as well as awareness of asymptomatic disease (p = 0.003) and extrapulmonary involvement (p = 0.046). They were also more likely to correctly reject misconceptions related to TB transmission.However, overall correct TB knowledge was not significantly associated with perceived risk (χ² = 0.008, p = 0.927). High risk perception was significantly associated with being single/widowed (p = 0.003), higher education (p < 0.001), higher socio-economic status (p < 0.001), skilled occupation (p < 0.001), and a family history of DM (p = 0.008). Age, sex, and duration of DM were not significantly associated with risk perception. CONCLUSION: Although more than half of the participants demonstrated correct TB knowledge, this did not translate into higher perceived risk, highlighting a critical knowledge-perception gap among patients with T2DM. While specific and clinically relevant knowledge components were associated with higher risk perception, general awareness alone was insufficient to evoke a sense of personal vulnerability. Educational strategies should therefore move beyond general information dissemination and focus on personalised risk communication that explicitly links DM with increased susceptibility to TB. Such interventions should emphasise the possibility of asymptomatic disease and promote timely screening and care-seeking behaviour.

OBJECTIVES: To examine the current performance of cancer screening programs in Italy, evaluate the evolving regulatory and clinical guideline framework, and discuss future opportunities for improving participation and equity through artificial intelligence. STUDY DESIGN: Narrative review and perspective analysis. METHODS: A systematic analysis of Italian national screening data, existing legal frameworks, and recent national and European clinical guidelines was conducted. Emerging applications of artificial intelligence within these frameworks were evaluated. RESULTS: Organized cancer screening in Italy is legally mandated under the Essential Levels of Care (LEA), yet actual population participation remains around 50% for breast and cervical screening, and lower for colorectal cancer. Significant geographic (North-South) and socioeconomic disparities persist. Recent frameworks, including the 2022 European Council recommendations, new European initiatives (ECIBC, ECICC, EC-CvC), and Italian guidelines (GISCi and GISMa-ISPRO), emphasize risk-based strategies and the regulated integration of artificial intelligence to optimize diagnostic accuracy and public health outreach. CONCLUSIONS: While artificial intelligence offers powerful opportunities to enhance performance and equity in Italian cancer screening, its success depends on integration within unified public health strategies that align with national and European guidelines.

OBJECTIVES: Bladder cancer is among the ten most deadly cancers in Canada. This study investigated income and education inequalities in bladder cancer mortality in Canada from 1990 to 2019. STUDY DESIGN: A time-trend analysis using national data. METHODS: A census division level dataset (n = 280) was created using the Canadian Vital Statistics Death Database (1990 to 2019), the Canadian Census of Population (1991, 1996, 2001, 2006, 2016), and the National Household Survey (2011). Age-standardized relative and absolute Concentration index (RC and AC, respectively) was used to quantify the magnitude of income and education inequalities in bladder cancer mortality among males and females. RESULTS: Crude bladder cancer mortality in Canada rose significantly from 1990 to 2019, increasing from 6.31 to 9.13 deaths per 100,000 population in males and from 2.79 to 3.90 in females. Persistent income- and education-related inequalities in bladder cancer mortality were observed, as age-standardized RC and AC indices were predominantly negative and statistically significant in several years. There was some evidence of change in income-related inequality over time, with indices suggesting widening inequality among females and only limited evidence of a modest reduction in inequality among males. CONCLUSIONS: Bladder cancer mortality was higher among lower-income and less-educated Canadians, reflecting socioeconomic inequalities that may relate to incidence and treatment access. The observed variations in income-related trends across sexes highlight the importance of further research into sex-specific determinants of these inequalities.

OBJECTIVES: Social impact bonds (SIBs) represent a financial strategy designed to fund projects where financing is not tied to specific activities and outputs, but to the outcomes they aim to deliver. Although the project involves a wide range of stakeholders, the dynamics among them remain largely unexplored. To accelerate the advancement of SIBs in healthcare, this study aimed to clarify the challenges and connections between stakeholders with their perspectives for overcoming them. STUDY DESIGN: A qualitative investigation, underpinned by semi-structured interviews and grounded theory METHODS: Eight individuals were assembled via snowball sampling. Data were collected from June to August 2023. RESULTS: Nine categories of relationships were formed among stakeholders: conflictual, cooperative, and behaviour-change-enhancing relationships. The challenges and barriers faced by stakeholders were identified. Significant hurdles were found regarding the cultural context, the structure of the National Health Service, and stakeholder affinity for SIBs. CONCLUSIONS: This study illustrated the practical complexity of social impact bond implementation in healthcare and identified three pillars of success: decisive leadership, social impact outcome metrics, and a transparent framework aligned with public interests. Standardised evaluation tools and cross-system evidence remain scarce, calling for comparative research to refine SIB design and assess long-term value across diverse healthcare contexts.

BACKGROUND: Persistent urban-rural disparities in emergency medical service (EMS) demand constitute a core challenge to global public health equity. Existing research focuses predominantly on static comparisons of demand scale, with limited systematic analysis of spatiotemporal dynamics, shock responsiveness, and heterogeneous driving mechanisms across urban and rural EMS systems. Conventional one-size-fits-all regression models further widen the gap between academic findings and on-the-ground EMS operations. METHODS: Taking Ningbo, China as the case, we defined urban and rural units in full alignment with official EMS response zoning. Using 189,506 validated dispatch records from October 2022 to September 2025 (spanning the exogenous shock of China's COVID-19 policy adjustment), we applied a sequential framework integrating global negative binomial regression (GNBR) and geographically weighted regression (GWR) to compare spatiotemporal patterns and identify system-specific demand drivers. RESULTS: Urban EMS demand showed strong positive spatial autocorrelation (Global Moran's I = 0.47, p < 0.01) with contiguous high-demand clusters, and exhibited marked volatility across monthly, diurnal, and weekly scales alongside high sensitivity to policy shocks. Rural EMS demand displayed weak spatial autocorrelation (Global Moran's I = 0.25, p < 0.01) with scattered small-scale agglomeration, and maintained stable temporal patterns decoupled from external disruptions. Driving mechanisms differed structurally: urban demand was driven primarily by population aging and built environment intensity with significant spatial nonstationarity, while rural demand was shaped by traffic accessibility, localized service hubs, and terrain conditions. Based on these findings, we formalize two distinct EMS demand patterns: spatiotemporal coupling in urban areas and spatiotemporal independence in rural areas. CONCLUSIONS: This study advances theoretical understanding of urban-rural EMS demand heterogeneity beyond superficial scale comparisons. The practice-aligned sequential modeling framework provides a scalable analytical approach for heterogeneous health service research, and delivers evidence for targeted EMS planning, optimized resource allocation, and improved healthcare equity.

INTRODUCTION: There are still some gaps in the knowledge about food insecurity (FI) as a determinant of quality of life (QoL); for example, it is not known whether there is a dose‒response relationship, whether these associations occur longitudinally, and how they behave in a population where the target audience is not composed of people affected by health problems. METHODS: This work prospectively analyzed the association between QoL and FI in individuals living in a socioeconomically disadvantaged Brazilian municipality between 2014 and 2019. This was a longitudinal prospective cohort study involving 225 individuals from families residing in a municipality with high social vulnerability in the northeast semiarid region of Brazil. The present study considered QoL as the dependent variable and food insecurity (FI) as the main independent variable. Multivariate analyses were conducted using mixed-effects regression, separately for each QoL domain. RESULTS: Baseline results showed mean QoL domain scores of 70.62 for Social Relationships, 69.42 for Physical Health, 64.77 for the Psychological domain, and 57.55 for the Environmental domain. Among these, only the Physical Health domain exhibited a statistically significant change at follow-up, with a mean reduction of 2.9 points. Multivariate analysis demonstrated an inverse association between FI and QoL scores in the Psychological and Environmental domains. Under conditions of moderate FI, scores declined by 4.728 points in the Psychological domain (p = 0.041) and 7.610 points in the Environmental domain (p = 0.000) over time. At the severe FI level, these reductions were more pronounced, reaching 9.465 points (p = 0.003) and 10.138 points (p = 0.000), respectively. CONCLUSION: The results presented in this cohort support the hypothesis that the phenomenon of FI was associated with poorer QoL outcomes over time.

BACKGROUND: Sociodemographic characteristics, health status, and access to health care are important determinants of health behaviors and may shift during periods of health system disruption such as the COVID-19 pandemic. This study aimed to examine whether these determinants were associated with self-medication and whether the prevalence of self-medication changed in Türkiye before and during the COVID-19 pandemic. METHODS: This study used data from the Türkiye Health Survey conducted in 2019 (n = 16,253) and 2022 (n = 21,444), which was designed to provide national-level estimates for Türkiye. Descriptive analyses and chi-square tests were used to compare the prevalence of self-medication across survey periods. Multivariable modified Poisson regression models with robust variance were estimated separately for the pre-COVID-19 and during-COVID-19 periods to identify factors associated with self-medication and to estimate adjusted prevalence ratios (aPRs) with 95% confidence intervals. To assess whether associations differed between the two periods, pooled modified Poisson regression models were constructed including an indicator for survey period and interaction terms between the COVID-19 period and selected determinants. The statistical significance of interaction effects was evaluated using global Wald chi-squared tests. RESULTS: The prevalence of self-medication increased significantly from the pre-COVID-19 period (34.9%) to the during-COVID-19 period (38.8%) (p < 0.001). In pooled analyses, self-medication remained more prevalent during the COVID-19 period (aPR = 1.11, 95% CI: 1.08-1.14). Across both survey periods, higher prevalence of self-medication was observed among women, individuals with higher educational attainment, those reporting moderate or severe bodily pain, individuals with long-standing illness, tobacco or alcohol users, and those experiencing unmet health care needs due to waiting lists. Global interaction tests indicated that the associations of educational attainment, age group, and health insurance coverage with self-medication differed significantly between the pre- and during-COVID-19 periods, whereas the associations with gender, long-standing illness, and self-perceived health remained stable. CONCLUSIONS: Self-medication prevalence was higher during the COVID-19-period survey in Türkiye, and the associations between self-medication and several sociodemographic and health-related determinants differed between survey periods. These findings suggest that changes in health care access and perceived health needs occurring during public health crises may be associated with differences in self-medication patterns, highlighting the importance of monitoring self-medication behaviors and supporting vulnerable population groups.

BACKGROUND: Municipalities influence population health outcomes both directly (e.g., fluoridation, road safety, and tobacco control) and indirectly through broader social, cultural, and environmental determinants of health such as housing, transportation, income, and social services. While intersectoral partnerships with public health systems are promoted as a policy tool for addressing complex health inequities, evidence on their models, effectiveness, and outcomes remains limited. METHODS: This scoping review aimed to map the literature on municipal-public health partnerships, with a focus on partnership models, reported outcomes, and the barriers and facilitators shaping their success. From 1,392 records, 105 studies were included. RESULTS: Two broad partnership models emerged: (1) ad-hoc, project-based collaborations, and (2) institutionalized collaborations, including intergovernmental relations, Health in All Policies, and strategic planning arrangements. Barriers included inadequate funding (48 studies), cultural and relational mismatches (33), system fragmentation and data-sharing challenges (32), and additional sub-themes under governance or leadership gaps. Facilitators included community engagement (34), capacity building (33), and sub-themes related to strong leadership or policy champions. Most studies (65%) focused solely on the implementation process of partnerships, while only nine studies (8%) examined health outcomes, reporting associations with improvements in areas such as smoking cessation and transportation equity. Municipal-public health partnerships are diverse yet under-evaluated, with the literature still dominated by process-focused studies and limited outcome or impact assessments. CONCLUSION: Recent evaluation guidance calls for broader outcome, impact, economic, and mixed-methods approaches, not only causal designs, so partnerships can be meaningfully assessed for their contributions to health equity and population health outcomes.

BACKGROUND: Smartwatches and other wearable technologies have become increasingly popular for health monitoring, offering potential benefits in the early detection of cardiac arrhythmias such as atrial fibrillation (AF). Despite their expanding use, limited data exist regarding public perceptions and usage patterns of these devices in Saudi Arabia. Understanding these perceptions is essential to inform strategies for digital health integration and preventive cardiovascular care. OBJECTIVE: This study aimed to evaluate public perceptions, usage patterns, and factors influencing acceptance of smartwatches for early detection of cardiac arrhythmias among adults in Saudi Arabia. METHODS: A cross-sectional study was conducted between May and October 2023 across five major regions of Saudi Arabia. A total of 459 adults aged ≥ 22 years participated through structured face-to-face interviews using a validated questionnaire adapted from prior studies. Descriptive statistics summarized demographic characteristics and usage trends, while Poisson regression analysis identified determinants of positive perceptions toward wearable technologies. RESULTS: Nearly half of the respondents (46.4%) reported using wearable devices for health monitoring, with smartwatches being the most preferred (42.0%). Among smartwatch users, (35.2%) had received notifications of cardiac arrhythmia through their devices. Most participants (76.5%) expressed willingness to use smartwatches for arrhythmia detection, and (48.1%) strongly agreed that wearable technologies could contribute to the early diagnosis and monitoring of arrhythmia. Younger adults (22-51 years) demonstrated significantly more positive perceptions compared to those > 51 years (p < 0.05). Previous experience with wearables was also a significant predictor of favorable perception (p = 0.015). Educational level showed a positive but non-significant trend (p = 0.061), while gender and cardiovascular history were not associated with perception. CONCLUSION: The Saudi public shows a high level of awareness and positive perception toward using smartwatches for early cardiac arrhythmia detection. Younger age and prior experience with wearables were the strongest predictors of acceptance, underscoring the importance of digital literacy and user familiarity. Integrating smartwatches into preventive cardiology and public health initiatives-supported by education and clinical validation-may enhance early arrhythmia detection and promote proactive heart health management in Saudi Arabia.

Pre-pregnancy overweight and gestational diabetes mellitus (GDM) increase the risk of accelerated fetal growth, but the effect of their individual or combined exposure on infant growth trajectory remains unclear. Clarifying whether these exposures will lead to sustained or time-limited growth patterns is essential for developing tailored, time-sensitive early childhood monitoring strategies.Methods We analyzed a population-based cohort of 16,712 mother-infant pairs from Jiangsu Province (2024) using longitudinal data. Infant weight was measured at birth, 1, 3, and 6 months. Linear mixed effects models were employed to examine the independent and joint associations of pre-pregnancy overweight and GDM with infant weight-for-age z-scores (WAZ), examining how the associations changed with infant age.Results Pre-pregnancy overweight showed a strong, positive association with higher infant WAZ (β = 0.160, 95% CI: 0.130 to 0.191), with no statistically significant change over time (overweight × age interaction: β = 0.005, 95% CI: 0.000 to 0.009; P = 0.060). In contrast, GDM alone had a statistically significant but relatively small initial effect (β = 0.065, 95% CI: 0.031 to 0.100), which significantly attenuated from birth to 6 months (GDM × age interaction: β = -0.008, 95% CI: -0.013 to -0.002; P = 0.006). The combined exposure yielded the highest initial β coefficient (β = 0.217, 95% CI: 0.175 to 0.259) and the most rapid attenuation (combined × age interaction: β = -0.017, 95% CI: -0.023 to -0.010; P < 0.001). At 6 months of age, the adjusted mean WAZ remained highest in the combined exposure group. The combined effect was approximately additive in magnitude (β_combined ≈ β_OW + β_GDM), and additive interaction metrics (RERI = 0.001, 95% CI: -0.112 to 0.114; AP = 0.005, 95% CI: -0.582 to 0.592; S = 1.01, 95% CI: 0.88 to 1.15) indicated no statistical additive interaction, with confidence intervals including the null values.Conclusions Different growth patterns were found in this study: pre-pregnancy overweight showed no statistically significant attenuation over the study period, while GDM's influence was time‑limited. The combined exposure presents peak early risk that moderates over time. Clinically, infants exposed to both maternal pre-pregnancy overweight and GDM (the combined exposure group) should receive the most intensive growth monitoring during the first six months of life. These findings highlight the necessity of developing targeted monitoring protocols and implement risk stratification and personalized interventions based on maternal metabolic profiles.

BACKGROUND: Understanding the relationship between under-five mortality rate (U5MR) and economic development is essential for promoting global child health and advancing health equity. This study analyzed the spatiotemporal patterns of U5MR and its associations with macroeconomic indicators from 2000 to 2023. METHODS: Panel data from 158 countries were used to analyze to characterize the spatial distribution of U5MR in 2023 and regional trends in the average annual percent change (AAPC) of U5MR from 2000 to 2023. Spearman correlation analysis, lagged analysis, and panel Granger causality tests were conducted to evaluate the associations and directionality between the U5MR and gross domestic product (GDP), GDP per capita (GDPpc), GDP growth rate, and inflation. RESULTS: In 2023, U5MR remained markedly higher in sub-Saharan Africa than in other regions. From 2000 to 2023, U5MR declined more rapidly in Africa and parts of Asia, whereas declines were slower in Europe and North America. Regional correlation indicated that the AAPC of U5MR was significantly negatively associated with the AAPCs of GDP and GDPpc in Asia (r = -0.505; r = -0.605) and Europe (r = -0.368; r = -0.619), and with the AAPCs of GDP in Africa (r = -0.374). No significant associations were observed in the North America, South America or Oceania. Lagged analyses showed that GDP and GDPpc maintained consistently negative associations with U5MR across all lag periods. In contrast, the significance of the associations of GDP growth rate and inflation with U5MR varied across lag periods. Granger causality tests confirmed a bidirectional relationship between GDPpc and U5MR at the optimal lag order of 4. However, the causal effect from GDPpc to U5MR is not robust to lag order selection. U5MR exerts a unidirectional Granger causal effect on inflation. CONCLUSIONS: This study demonstrates that macroeconomic factors shape U5MR with significant regional disparities and heterogeneous lagged effects. Regional authorities should adopt differentiated strategies: prioritizing economic development in Asia, Europe, and Africa, while implementing health-focused improvement programs in North America, South America, and Oceania. Governments should maintain stable long-term economic and income growth, and increase sustained public investment in child health services and nutrition programs to lower U5MR. Given that lower U5MR drives economic growth, sustaining its decline is a long-term economic priority. TRIAL REGISTRATION: Clinical trial number: not applicable.

BACKGROUND: Street vending is a non-formal, vital domestic workforce in most developing nations. The street vendors operate in an unregulated environment and are frequently exposed to hazardous environmental pollutants, which is linked to chronic respiratory health problems. However, there is underreporting of this public health problem in literature, creating a blind spot in global health. OBJECTIVE: To assess the association between air quality, occupational exposure characteristics, and pulmonary function among street vendors in an urban community. METHODS: A cross-sectional study was conducted among 298 street vendors in Chennai city, India. Pulmonary function was assessed using peak expiratory flow rate (PEFR) and breath-holding time (BHT). Respiratory symptoms were evaluated using the Modified Borg Dyspnea Scale. Air quality was measured using the Air Quality Index (AQI). Linear regression analysis identified independent variables associated with PEFR. RESULTS: The mean age of participants was 38.5 ± 11.08 years, with 65.4% female. Mean PEFR was 376.1 ± 71.39 L/min, and BHT was 33.32 ± 9.07 s. High prevalence of respiratory symptoms was observed: coughing at work (58.7%) and morning phlegm (44%). Variables negatively associated with the PEFR included years working as a vendor (β=-3.34, p < 0.001), daily outdoor exposure hours (β=-6.48, p < 0.001), annual AQI (β=-1.80, p = 0.002), weight (β=-1.19, p < 0.001), and dyspnea at rest. BHT showed a strong positive association with PEFR (β = 3.03, p < 0.001). Only 2.3% of vendors reported using masks during work. CONCLUSION: Street vendors demonstrate measurable respiratory compromise associated with cumulative occupational exposure to air pollution. Long-term exposure metrics (annual AQI, years of work) were stronger indicators than short-term measures, emphasizing the chronic nature of occupational health risk. Findings underscore the need for targeted respiratory screening, awareness programs, and feasible protective interventions for this vulnerable informal workforce.

BACKGROUND: Unsustainable dietary patterns contribute substantially to climate change, biodiversity loss, and the growing global burden of non-communicable diseases. University years represent a critical transitional period during which lifelong eating behaviors are shaped. Understanding whether positive attitudes toward healthy eating are associated with sustainable dietary behaviors may inform integrated public health strategies targeting both health and environmental outcomes. This study examined the relationship between healthy eating attitudes and sustainable nutrition behaviors among Turkish university students and explored associated demographic factors. METHODS: A cross-sectional study was conducted between December 2023 and October 2024 among 610 university students aged 18-26 years. Data were collected using structured self-report questionnaires. Healthy eating attitudes were assessed using the Attitude Scale for Healthy Nutrition (ASHN), and sustainable dietary behaviors were measured using the Behaviors Scale Towards Sustainable Nutrition (BSSN). Non-parametric tests, Spearman correlation analysis, confirmatory factor analysis, and structural equation modelling (SEM) were performed. RESULTS: Participants demonstrated generally high levels of healthy eating attitudes. A weak but statistically significant positive correlation was observed between overall healthy eating attitudes and sustainable dietary behaviors (r = 0.182, p < 0.001). SEM indicated that healthy eating attitudes were positively associated with sustainable nutrition behaviors (β = 0.542, p < 0.001). Non-smokers and female students exhibited significantly higher sustainable nutrition behavior scores compared to smokers and male students (p < 0.05). CONCLUSIONS: Healthy eating attitudes were positively associated with sustainable dietary behaviors among university students. Although the strength of the association was modest, the findings suggest that health-oriented attitudes may support environmentally responsible dietary practices. Public health interventions that integrate sustainability principles into university-based nutrition education and campus food policies may represent a promising strategy to advance both human and environmental health. Longitudinal studies are needed to clarify causal pathways.

BACKGROUND: Tuberculosis (TB) remains a major public health challenge globally and in Kazakhstan, despite progress in reducing incidence. Increasing evidence highlights the role of social and structural determinants in shaping TB risk, disease progression, and treatment outcomes. However, limited research has explored how decision-makers conceptualize these factors and identify system-level gaps in TB control. This study aimed to examine regional decision-makers' perspectives on TB burden, social protection, health system capacity, and governance in Kazakhstan. METHODS: A qualitative study was conducted using in-depth, semi-structured interviews with 12 decision-makers from six regions of Kazakhstan, including representatives of regional health authorities and local governance structures. Participants were purposively sampled to ensure diversity in institutional roles and geographic context. Interviews were conducted between August and December 2020, audio-recorded, transcribed verbatim, and analyzed using inductive codebook thematic analysis supported by ATLAS.ti software. The study followed COREQ guidelines. RESULTS: Six major themes were identified. Participants consistently framed TB as a condition closely linked to structural inequality rather than solely a biomedical issue. Risk was perceived as concentrated among socially and geographically vulnerable populations, particularly in rural areas with limited access to care. A key finding was the identification of a "biomedical-social gap," whereby strong diagnostic and treatment capacity was perceived as insufficiently connected to social protection, outreach, and governance mechanisms. Participants attributed this gap to fragmented social assistance, uneven support for transport, food, and income-related needs, workforce and infrastructure constraints, inequities in rural access, and insufficient institutionalization of NGO involvement. Sustaining political commitment and non-stigmatizing public awareness was also identified as important for long-term TB control. CONCLUSIONS: Regional decision-makers perceived TB control in Kazakhstan as constrained by fragmented linkages between biomedical services, social protection, NGO outreach, rural access support, and intersectoral governance mechanisms. Strengthening patient-centered social support and coordination across clinical, social, and civil society sectors may help reduce perceived fragmentation and support more equitable TB control.

BACKGROUND: Gonorrhea is a global public health priority due to substantial morbidity, sustained transmission, and increasing antimicrobial resistance; however, its epidemiology in Jordan and other settings with limited surveillance and research, such as in the Middle East and North Africa, remains inadequately characterized. METHODS: Data from 8,779 individuals aged ≥ 15 years tested for current Neisseria gonorrhoeae (NG) infection at Biolab Diagnostic Laboratories in Jordan between 2014 and 2025 were analyzed. A cross-sectional design was used to estimate prevalence, assess temporal trends, and identify factors associated with infection among all 8,779 individuals. Retrospective cohort designs were used to assess incidence among 784 individuals and, exploratorily, clearance among 5 individuals with repeat testing. RESULTS: NG prevalence, defined as ever having a NAAT-positive test, was 0.4% (95% CI: 0.2-0.5%) overall and 0.1% (95% CI: 0.0-0.2%) among individuals tested for visa-related requirements. Corresponding point prevalence, based on one randomly selected test per individual, was 0.3% (95% CI: 0.2-0.5%) and 0.1% (95% CI: 0.0-0.2%), respectively. NG positivity was substantially higher in clinically motivated testing compared with visa-related testing and among individuals with more frequent testing. No consistent patterns were observed by age, sex, or governorate, and there was no evidence of a temporal decline. In the retrospective cohort, three incident infections were identified over 1,167 person-years of follow-up, yielding a cumulative incidence of 0.49% (95% CI: 0.16-1.53%) after two years of follow-up and an incidence rate of 2.57 per 1,000 person-years (95% CI: 0.83-7.97). In exploratory analysis, nearly all individuals with follow-up after a positive test had a subsequent negative result within 10 days. CONCLUSIONS: Observed NG prevalence and incidence rate in Jordan were low. However, high positivity in clinically motivated testing contexts and the absence of a temporal decline indicate ongoing transmission that requires control. Strengthening surveillance, expanding targeted testing and treatment among higher-risk populations, and integrating NG antimicrobial resistance monitoring are needed to inform prevention and control efforts.

INTRODUCTION: Up to 75% of children treated for severe acute malnutrition (SAM) relapse within six months of recovery, yet evidence on post-discharge interventions remains limited. We conducted a formative assessment to understand how small-quantity lipid-based nutrient supplements (SQ-LNS) could be integrated in post-discharge care to prevent relapse. OBJECTIVE: This study aimed to inform whether and how a program integrating SQ-LNS into post-discharge monitoring could be implemented in Mali. Specifically, we aimed to: 1) identify barriers and enablers to post-discharge monitoring, 2) develop one or more post-discharge models based on recommendations, 3) understand the feasibility of these model(s), 4) describe acceptability of the model(s) and product, and 5) propose a final model to be piloted at larger scale. METHODS: This formative study comprised two iterative phases conducted between September 2024 and May 2025. In exploratory Phase One, we conducted semi-structured interviews with 12 caregivers of children with SAM and eight treatment providers, in triangulation with 13 focus groups among caregivers, health care workers (HCW's), and supervisors. Themes included current practices, anticipated challenges, and service delivery preferences. Findings informed a confirmatory Phase Two involving four direct observations of three delivery models implemented at four sites and 13 interviews with similar participants. Textual data were coded and thematically analyzed using Dedoose software. RESULTS: Although national guidelines recommend routine post-discharge monitoring for SAM children, it was rarely practiced due to limited awareness among HCW's. Both caregivers and HCW's supported the idea of post-SAM monitoring, preferring on-site over home visits for feasibility. Caregivers valued growth monitoring, interacting with HCW's, and nutritional supplementation. While unfamiliar with SQ-LNS, caregivers viewed it positively based on their experience with therapeutic foods. Three delivery models were tested: (1) weekly visits for one month transitioning to fortnightly thereafter, (2) fortnightly visits and program days, and (3) fortnightly visits for caregivers and weekly program days at the health site. Model three proved most feasible for caregivers and providers. CONCLUSION: This formative research informed a program design that aligns with caregiver preferences and health system capacity, requiring minimal external support. Fortnightly post-discharge monitoring paired with SQ-LNS supplementation at treatment sites is recommended.
