Objective: To verify the association between perceived social & emotional support and self-reported food insecurity in the United States Design: Cross-sectional secondary data analysis Setting: Behavioral Risk Factor Surveillance System (BRFSS) data from 2024, collected via a nationwide telephone survey. Food insecurity was defined as responding always, usually, or sometimes to "During the past 12 months how often did the food that you bought not last, and you didn't have money to buy more?" Social support was measured using a BRFSS item assessing the frequency with which respondents received the social and emotional support they needed. Adjusted logistic regression models were used to assess the relationship between these variables while controlling for a wide variety of demographic, socioeconomic, and health status factors. Participants: Adults (n = 190,577) aged 18-80 years old (72.3% non-Hispanic White) Results: Individuals who reported only "sometimes" receiving the social and emotional support they need were more likely to report food insecurity as compared to those who "always" receive such support (aOR = 1.75; 95% CI 1.56, 1.96). Conclusions: These findings indicate that decreased social support may put individuals at higher risk of food insecurity. Future work should seek to understand the mechanisms of this association to inform targeted policy and other interventional programs.

While SARS-CoV-2 and influenza continue to place a significant burden on population health, within-household differences in decisions towards vaccination and seeking care across these two pathogens, and across sociodemographic groups, remain largely unexplored. By conducting a household-level survey in Illinois, we found that many individuals made inconsistent decisions about vaccination: among all adults, 29% were vaccinated for only one of COVID-19 or influenza, and among those with children in the home, 39% lived with a child whose influenza or COVID-19 vaccination status differed from their own. A higher proportion of adults were vaccinated against COVID-19 compared to influenza, while the opposite was true for those younger than 18 years old. These differences hold even when accounting for disparities in coverage by age, race/ethnicity, political affiliation, and socioeconomic status. While vaccinated individuals consistently reported wanting to protect themselves or others, those who declined vaccination reported highly heterogeneous reasons ranging from resource constraints to distrust or misconceptions about vaccination. These differences are even more pronounced for COVID-19, with larger partisan gaps and higher refusal driven by safety concerns, lack of trust, or religious reasons than those who decide not to get the influenza vaccine. In contrast to vaccination, the decision to seek medical care when sick showed opposite sociodemographic trends, that are likely attributable to illness severity. Our findings highlight that closing gaps in COVID-19 and influenza vaccination coverage will require an integrative strategy that accounts for diverse motivations, fears, and barriers to access, while addressing social inequalities common to both diseases.

Introduction Access to quality early childhood development (ECD) services remains limited for families working in economic settings in many low-and middle-income countries. This study examined the associations between participation in integrated ECD centres of integrated ECD centres located in market and cross-border communities in Rwanda and childcare access, child nutrition, caregiving practices, and developmental outcomes. Methods A repeated cross-sectional pre-post evaluation without a comparison group was conducted between 2023 and 2025 across eight markets and cross-border ECD centres in Rwanda. Quantitative data were analyzed with logistic regression models adjusted for socio-demographic characteristics, while qualitative data were analysed thematically. University of Rwanda College of Medicine and Health Sciences Institution review board approved the study (No.366/CMHS IRB/2023). Results The proportion of children aged 6-23 months who achieved minimum meal frequency increased from 26.6% to 57% (AOR=2.35; 95% CI: 1.01-5.49), and those meeting minimum acceptable diet increased from 15.4% to 51.4% (AOR=4.51; 95% CI: 1.77-11.45). Stunting declined from 32.6% to 15.7% (AOR=0.45; 95% CI: 0.32-0.63) and underweight from 9.3% to 4.3% (AOR=0.55; 95% CI: 0.32-0.97). The proportion of children aged 24-59 months who were developmentally on track increased from 77.9% to 93.8% (AOR=3.85; 95% CI: 2.23-6.65). Households reported higher income at endline, and the centres generated strong demand for childcare services. However, reports of scolding and physical punishment increased between surveys. Conclusions Integrated ECD centres in market and cross-border settings were associated with improved child feeding practices, nutritional status, and developmental outcomes among children from vulnerable working families in Rwanda. Place-based childcare models may represent a promising strategy for expanding access to integrated ECD services while supporting womens economic participation in economic settings.

Objective: The study aimed to describe the challenges, best practices, and lessons learned during meningitis vaccination campaigns conducted in the context of COVID-19 in Cameroon in 2020. Results: During the prevention campaigns, 3,460 individuals were selected. All were tested before the campaign (100%). Eight cases were positive, representing a positivity rate of 0.23% (8/3,460). The campaign was carried out using a fixed strategy in health facilities and prisons and a fixed-temporary strategy in communities. Most health areas received sufficient quantities of COVID-19 equipment for some items and insufficient quantities for others. No screening was done during or after the campaign. The main difficulties encountered were compliance with social distancing and the continuous wearing of gowns. The challenges faced were the screening of actors and the use of personal protective equipment. Lessons learned: aspects related to COVID-19 impacted the speed of the campaign. Vaccination coverage ranged from 91% to 140% in prisons on the one hand, and from 35% to 112% in the health areas surrounding prisons on the other. The campaign in the context of COVID-19 was effective. Compliance with barrier measures was not optimal due to difficulties encountered with aspects such as social distancing, continuous wearing of gowns, screening of participants during and after the campaign, and insufficient personal protective equipment.

Background People with severe mental health conditions (SMHC) and caregivers in South Africa experience high rates of poverty. The PRIZE feasibility trial found that recovery groups were broadly acceptable and feasible and potentially effective in reducing relapse. Addressing economic needs was identified as a means to increase impact. This study aimed to understand experiences of financial insecurity and acceptability of poverty alleviation interventions as an adjunct to psychosocial interventions amongst people with SMHC and caregivers. Methods We conducted two focus group discussions and 12 in-depth interviews in isiXhosa with a total of 14 people with SMHC and 13 caregivers who had participated in PRIZE in Eastern Cape Province, South Africa. An inductive thematic analysis was conducted. Results We identified four major themes. Theme 1: Financial insecurity as a defining influence on life. We found that financial security was crucial to recovery, through bringing status and dignity. However, participants experienced substantial financial insecurity, which impacted on social and mental wellbeing. Financial insecurity was entrenched due to fractured and violent communities, cycles of debt and stigma amongst employers. Theme 2: Government disability grants are not a panacea. Difficulties accessing disability grants included problems attending assessments and rejection of applications. Whilst they were generally welcomed, receipt of disability grants sometimes caused problems such as increased stigma and family disagreements about how the money should be spent. Theme 3: Group savings offer conditional hope if carefully managed. Several caregivers had longstanding experiences of stokvels (community-based credit unions). However, some were fearful of group members absconding with funds. Participants emphasised that trust, safety and fairness are essential for successful group savings. Theme 4: Income-generating activities are desired but need capital and come with safety concerns. Many had ideas and motivation for small businesses but stressed the need for financial capital, skills training and financial literacy support. There were serious concerns that owning a business or gaining wealth could make one a target of crime. Conclusion Poverty alleviation interventions could positively impact on the wellbeing of people with SMHC and caregivers in South Africa as an adjunct to psychosocial interventions and psychiatric care. Approaches could include supporting access to social protection or existing savings groups, and nesting new savings groups or income generation initiatives into psychosocial interventions. Any model would need to incorporate robust mechanisms to ensure the safety of participants. All approaches would be enhanced by parallel social and public health interventions to build social capital and reduce violence in neighbourhoods.

Introduction: Socioeconomic deprivation is often associated with poorer health outcomes, but some studies suggest the opposite for Lyme disease. Here we test two hypotheses to explain this: differences in (i) local landcover of high risk habitats such as woodlands (landscape hypothesis) and (ii) outdoor recreation in such habitats (behaviour hypothesis). Methods: We analysed reported Lyme disease incidence data for 824 data zones in the city of Glasgow, UK, against deprivation rank (based on indicators relating to income, employment, health, education, crime and housing). We then tested how these relate to woodland cover and indices of urban greenspace usage (per capita and per ha of greenspace). Additionally, we measured Lyme disease hazard (density of infected ticks) in 32 greenspaces and tested relationships with deprivation, woodland and greenspace usage. Results: More advantaged data zones (data zones with low deprivation rank) had higher Lyme disease incidence. These areas had more woodland and woodland cover was positively correlated with both Lyme disease incidence and hazard. Deprivation did not correlate with greenspace usage, nor did greenspace usage correlate with Lyme disease incidence. Intensely used greenspaces had lower infected tick densities, consistent with a human disturbance effect on wildlife that carry ticks. Conclusions: Differences in woodland cover, but not outdoor recreation behaviour, can help explain our finding of higher Lyme disease incidence in more advantaged areas. However, to further test the behaviour hypothesis, we need more detailed data on outdoor recreation activity per capita both locally and in rural areas, as well data on mitigation behaviours.

Background: Self-reported confidence in health information seeking does not reliably predict accurate health knowledge, yet the population-level distribution of this discordance and its demographic predictors have received limited direct study. This study aimed to identify and characterize a Confident-Incorrect phenotype among U.S. adults: individuals with high perceived health information competence who simultaneously hold inaccurate or fatalistic beliefs about cancer. Methods: Cross-sectional analysis of HINTS 7 (N = 7,278). A Confidence Index (3-item digital literacy composite (Cronbach's = 0.674) and an Evidence-Consistent Knowledge Score (factual cancer knowledge minus a cancer fatalism composite; fatalism subscale = 0.563) were computed and combined into a discordance framework. Median-split classification produced four phenotypes. Gaussian Mixture Model clustering with four components provided moderate independent validation (inter-method agreement = 65.2%). Survey-weighted multinomial logistic regression (n = 5,771; McFadden pseudo-R2 = 0.129) examined phenotype predictors. Results: An estimated 20.3% of U.S. adults were classified as Confident-Incorrect. They reported confidence levels similar to Well-Informed adults (z = 0.72 vs. 0.82) but scored 2.8-fold lower on objective cancer knowledge (0.74 vs. 2.06 out of 4) and exhibited the highest cancer fatalism of any phenotype (3.17 vs. 1.65 out of 4). Only 14.3% correctly identified alcohol as a cancer risk factor (vs. 58.8% of Well-Informed adults). Cancer screening rates did not differ meaningfully across phenotypes. Lower education (OR = 0.754), Hispanic ethnicity (OR = 1.788), non-Hispanic Black race (OR = 1.893), higher social media use (OR = 1.097), and lower trust in scientists (OR = 0.749) independently predicted Confident-Incorrect membership. Conclusions: An estimated one in five U.S. adults is overconfident in health information competence while holding substantially inaccurate beliefs about cancer prevention. Cancer screening rates did not follow the expected gradient across phenotypes, a null finding that cautions against inferring immediate behavioral impact from observed belief gaps. Interventions targeting specific factual errors and cancer fatalism are more likely to reach this group than general health literacy programs.

ObjectiveTo assess the prevalence, determinants, and health associations of vitamin D deficiency among workers in Cikarang, Indonesia. MethodsCross-sectional study of 107 workers. Serum 25(OH)D was measured by ECLIA; deficiency was <20 ng/mL. Data included demographics, occupation, sun exposure, diet, anthropometry, laboratory parameters, and self-reported health. Analyses used t-test/Mann-Whitney U, chi-square, and multivariable regression. ResultsDeficiency was prevalent (57.9%; median 18.6 ng/mL). Males had higher levels (+7.60 ng/mL) and lower risk (OR 8.56), while younger age (<38.5 years) showed lower levels (-5.60 ng/mL) and higher risk (OR 4.73; all p<0.0001). Greater sun exposure increased levels, whereas sunscreen use and greater clothing coverage reduced them. Only sex and age remained significant. ConclusionVitamin D deficiency is common, especially among female and younger workers, with modifiable sun-avoidance behaviors contributing. LEARNING OUTCOMESO_LISummarize the prevalence and key determinants of vitamin D deficiency among industrial workers in equatorial Indonesia, contributing to limited occupational health data in this setting. C_LIO_LIHighlight the role of modifiable behaviors--particularly sun exposure and sun-avoidance practices--in influencing vitamin D status among workers. C_LIO_LIEmphasize the need for targeted workplace interventions, including safe sun exposure strategies and nutritional support, especially for high-risk groups such as female and younger workers.

Background: Non-communicable diseases (NCDs) account for approximately 75% of global deaths, with 79% occurring in low- and middle-income countries. Tobacco use remains a major modifiable risk factor, contributing to more than 8 million deaths annually. In Zambia, evidence on tobacco use among individuals with hypertension, diabetes mellitus, and cardiovascular disease remains limited. This study assessed the prevalence and determinants of tobacco use among adults with NCDs in Zambia. Methods: We conducted a secondary analysis of the 2017 Zambia STEPS survey. The analytic sample included 716 adults aged 18-69 years with self-reported hypertension, diabetes, and/or cardiovascular disease. Tobacco use was defined as current smoking or smokeless tobacco use. Multivariable logistic regression was used to estimate adjusted odds ratios (AORs), accounting for the complex survey design. Results: Among 716 participants, 65.5% had hypertension, 7.7% diabetes, and 26.8% cardiovascular disease; 89.5% had multimorbidity. The overall prevalence of tobacco use was 12.2%. Prevalence was 12.2% among those with hypertension, 5.5% among those with diabetes, and 14.1% among those with cardiovascular disease. Tobacco use was significantly higher among males. Female sex was associated with lower odds of tobacco use (AOR = 0.16, 95% CI: 0.05-0.54, p = 0.004). Secondary education (AOR = 0.15, 95% CI: 0.03-0.66) and higher education (AOR = 0.04, 95% CI: 0.01-0.44) were protective. Alcohol consumption increased the odds of tobacco use (AOR = 5.23, 95% CI: 1.17-23.28). Conclusion: Tobacco use remains common among adults with NCDs in Zambia. Integration of tobacco cessation interventions into routine NCD care is urgently needed.

Introduction. Routine childhood immunisation is frequently disrupted in conflict-affected settings, leaving many children unvaccinated (zero-dose [ZD]). Their vaccination is now a global priority, but published evidence on restoring immunisation services in these settings is limited. We evaluated a nurse-led, community-based Expanded Programme on Immunisation adapted to a conflict-affected setting in Myanmar, focusing on factors associated with full immunisation (FI) among ZD children. Methods. This mixed-methods observational cohort study enrolled children from November 2023 to December 2025; analyses of FI outcomes were restricted to children enrolled >=18 months, with primary analyses focused on ZD children. Associations between programme delivery factors including vaccination opportunity (the ratio of vaccination sessions available to visits required for FI based on age and vaccination schedule [accelerated versus routine]) and FI were assessed using mixed-effects logistic regression with a random intercept for site. Programme cost and qualitative data from document review and questionnaires were also analysed. Results. Of 13,263 children enrolled, 6563 (49%) were in the analytic cohort; 2,684 (20%) were ZD. Among ZD, 452 (17%) were FI at 12 months and 1329 (50%) at 18 months. Accelerated schedule (OR 3.00, 95% CI 1.11-8.13) and greater vaccination opportunity (OR 2.1 per 0.5 unit increase in opportunity, 95% CI 1.8-2.4) were strongly associated with FI at 12 months, with smaller effects at 18 months. The cost per fully immunised ZD child was US$147, primarily reflecting substantial vaccine costs. Qualitative findings indicate that community engagement increased demand and access, but insecurity and logistical challenges limited service continuity and vaccination opportunities. Conclusion. FI improved over time but remained suboptimal through 18 months. Vaccination opportunity and schedule influenced the timing of FI, but sustained follow-up was critical for completion. Community-based delivery enabled restoration of immunisation services where formal systems had collapsed, demonstrating what is possible and what it demands in active conflict.

Abstract Background: The sanitation crisis poses a significant public health risk, leading to diseases like diarrhea, cholera, and typhoid, which impede children's health and development in developing countries like Uganda. Improving sanitation infrastructure is crucial for safeguarding child health and future generations. However, the link between sanitation and children's health is complex, influenced by various factors. This investigation in Gulu scrutinizes the correlation between sanitation practices and child well-being, considering moderating factors such as age, climate, and consistent water accessibility. Methods: The study used a convergent parallel design with equal priority. The Social Ecological Model, Social Learning Theory, and Diffusion of Innovations Model guided it. Researchers collected data from 10 health facilities and 317 households, using purposive and simple random sampling. They used sampling proportions proportional to village size within strata. The researcher analyzed quantitative data using SPSS with factor analysis, structural equation modeling, and multivariate analysis. To analyze qualitative data, they used DQA Minor Lite software, which facilitated thematic analysis. Results: The finding shows 56.8% of households had low socio-economic status. Sanitation was poor; 24.9% household had improved latrines, 20.5% had handwashing facilities with soap, and 68.1% used basic anal cleansing. For nutrition, 38.5% of children were malnourished by MUAC; by Z-scores, 28.7% were stunted, 16.4% underweight, 13.6% wasted. Diarrhea affected 62% of children. Climate worsened sanitation: 48.3% had latrines collapse from floods, and 63.4% of waterborne diseases occurred in both dry and wet seasons. Moderation analysis on childhood diarrhea shows that sociocultural factors ({beta} = -0.20, p < 0.001), sanitation ({beta} = -0.15, p < 0.001), and health system response ({beta} = -0.18, p < 0.001) reduced diarrhea. Climate change increased risk ({beta} = 0.15, p < 0.001) and moderated sanitation effects ({beta} = 0.01, p < 0.05). Models explained 10-14% variance. Age and water access had no moderating effect. While childhood malnutrition shows that sociocultural factors ({beta} = -0.43, p < 0.001) and health system response ({beta} = -0.13, p < 0.001) reduced malnutrition. Sanitation had no effect ({beta} = 0.01, p > 0.05). Age increased malnutrition risk ({beta} = 0.28, p < 0.01) and moderated sociocultural effects ({beta} = 0.16, p < 0.001), but not sanitation. The model explained 21% variance, R{superscript 2} = 0.21, p < 0.001. Conclusion: Sociocultural improvements and health system responses lower both diarrhea and malnutrition. Climate worsens diarrhea and alters sanitation's impact. Age worsens malnutrition and changes sociocultural effects. These findings are valuable for policymakers, healthcare professionals, and researchers

Background: The 2026 FIFA World Cup may bring over one million visitors to North America from around the globe to participate in mass gathering events. The nature of the event and recent news have raised concerns for some that the tournament could lead to infectious disease outbreaks or fuel existing epidemics. Objective: To systematically assess the infectious disease threat posed to the United States by the tournament. Design: A multi-institutional team evaluated pathogen-specific risk across three dimensions: importation, outbreak potential, and impact to identify a priority pathogen list. A systematic screening protocol ensured common criteria and that pathogen information was collected when necessary to inform inclusion. Results: Increased risk from the World Cup is near zero for 63 of 77 evaluated pathogens. Pathogens were predominantly excluded as threats due to low excess importation risk and low outbreak potential if introduced. The remaining priority pathogens fall into five categories: (a) mosquito borne pathogens with the potential for sustained transmission in some host cities, (b) seasonal respiratory viruses, (c) chronic infections with high prevalence outside the United States, (d) pathogens present in the United States with likely increased transmission at World Cup activities, and (e) high-consequence infectious threats. Limitations: Data availability is variable across diseases. Impact calculations may not reflect actual costs to host cities. Disease incidence in World Cup travelers may differ from national incidence rates. Conclusion: While infectious disease outbreaks at the 2026 FIFA World Cup are possible, in an already highly connected world where large gatherings are frequent, the elevated risk from the tournament is not as extreme as it first may seem.

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

Background: Sexual and gender minorities (SGM), including men who have sex with men (MSM) and transgender women, often face stigma, legal constraints, and limited access to sexual and reproductive health services. These conditions restrict prevention and care, increasing vulnerability to HIV and human papillomavirus (HPV) infections. While strong HIV-HPV interaction is documented in high-income settings, evidence from low- and middle-income countries remains limited. This study examines the burden, co-infection dynamics, and progression of HPV infection and anal dysplasia among MSM and transgender women in Pakistan. Methods: A cross-sectional study was conducted between September 2015 and October 2016 among men who have sex with men (MSM) and transgender women recruited from sexual health and antiretroviral therapy centers in Karachi. Eligible participants were aged [&ge;]18 years and self-reported anal sex within the past 6 months (N=298). Two anal specimens were collected for HPV DNA detection and genotyping using PCR, and anal squamous intraepithelial lesions (ASIL) were assessed cytologically using the Bethesda classification. Associations were estimated using Cox proportional hazards regression algorithms to derive prevalence ratios (PRs). Results: Among participants, 44% (n=133) were living with HIV. Overall HPV prevalence was 65.1%, rising to 87% among HIV-positive individuals compared to 48% among those without HIV ({chi}{superscript 2}p[&le;]0.001). Likewise 28.9% of participants living with HIV were infected with two or more than two types of HPV as compared with 18.8% participants without HIV ({chi}{superscript 2}p[&le;]0.001). HIV infection was strongly associated with HPV acquisition (adjusted PR 2.81, 95% CI 2.16-3.82). Among HPV-positive participants (n=194), 58.8% were co-infected with HIV. High-risk HPV was highly prevalent among those living with HIV (83.2% vs. 35.3% ({chi}{superscript 2}p[&le;]0.001)), with HPV16 as the dominant oncogenic type. Multiple HPV infections were more common among HIV-positive individuals ({chi}{superscript 2}p[&le;]0.001), and HIV seropositivity was 3.43 (95% CI: 2.55-3.51) times higher among those with high-risk HPV. Co-infected participants demonstrated prolonged smoking, longer duration of sex work, high-intensity sex work with limited condom negotiation, and higher prevalence of anal warts (all p<0.05). Anal dysplasia (ASIL) was present in 35% of participants and was higher among HIV-positive individuals (42.4% vs. 28.1%, p<0.001). HIV-HPV co-infection was independently associated with ASIL (adjusted PR 1.75, 95% CI 1.07-2.88), while high-risk HPV further amplified this risk (PR 3.04, 95% CI 1.75-5.26). Conclusion: These findings demonstrate a biological continuum in HIV-positive MSM and transgender women, where HIV increases HPV acquisition, persistence, and multiplicity, accelerating progression to anal dysplasia. This reflects a syndemic shaped by biological interaction and structural vulnerability. Integrating HPV screening and vaccination within HIV services is essential to interrupt progression to cancer in this high-risk population.

Background In northern Thailand, scrub typhus primarily affects rural and hill tribe communities, yet awareness is low. In 2020 we trained community health volunteers (CHVs) to raise awareness in their communities using a train-the-trainer approach. CHV knowledge rose dramatically. However, we did not assess the effectiveness in community members and our strategy relied heavily on CHVs, who have limited availability. Methods In a second phase, object of this manuscript and conducted in 2022-2023, after training CHVs we measured the effectiveness in community members and compared in-person sessions carried out by CHVs with sessions using video or audio recordings only. All materials included key information about scrub typhus transmission, symptomatology, prevention, and management and had been developed following feedback from participants from the first round of activities in 2020. Effectiveness was evaluated using a questionnaire assessing scrub typhus knowledge. CHVs were also asked to rate the feasibility of suggested preventative measures. Results A total of 74 community members participated in six sessions. Knowledge of scrub typhus significantly improved post-training (median score increased from 2 to 6 out of 9, p<0.001) and audio and video recordings were as effective as in-person trainings. CHVs noted that some of the preventative measures recommended are difficult to put in practice such as wearing gloves, washing daily after work, avoiding kneeling and resting on the ground, and washing clothes daily. Conclusions Our findings support the use of locally adapted multimedia training for scrub typhus prevention, showing that scalable formats can be as effective as in-person ones. Further collaborative work with people at risk should refine preventative messages to improve feasibility and acceptance.

Background/Objectives People living with HIV face overlapping hardship through medical, behavioral, and social needs that require an integrated and coordinated approach. Harlem United multiservice model provides healthcare, food assistance, housing support, harm reduction services, behavioral health counseling, case management, and much more to support their clients. This study is an examination on how the participation in the Harlem United multiservice model is associated with changes over time in client health, behavioral health, and social outcomes. Methods This study performed a longitudinal program evaluation examining Harlem United clients enrolled between January 2020 and January 2025 who remained engaged in services for a minimum of one year. Client outcomes were assessed across three time points: Baseline, Year 1, and Year 2. The sample included 154 clients at baseline (N=154) with a total of 428 observations (N=428). Quantitative measures that were assessed included program involvement, housing stability, PHQ4 scores, food insecurity, medication adherence, and viral suppression. Data was analyzed using IBM SPSS Statistics through descriptive statistics, frequency tables, and generalized estimating equation models (GEE) to account for repeated observation over time. Results Medication adherence and viral suppression remained consistently high across all time points in the longitudinal study suggesting that most clients were virally suppressed or undetectable at baseline. Housing stability was statistically significant Wald X2 (2) = 156.073, p < 0.001 with improvements noted in Year 1 and Year 2 compared to baseline. Program level was significantly associated with PHQ4 scores, Wald X2 (1) = 7.902, p = 0.005. Food insecurity was also associated with PHQ4 scores, Wald X2 (1) = 5.462, p = 0.019. Findings suggest that clients with higher PHQ4 scores were involved in more programs compared to clients only enrolled in 1-2 programs. Additionally, clients with higher PHQ4 scores were more food insecure highlighting the relationship between social needs and mental health. Conclusion: Findings suggest that the Harlem United multiservice model played a supportive role in the maintenance of health and social outcomes through medication adherence and viral suppression. Although, significant improvement was not reflected across several outcomes, the association between PHQ4 scores, food insecurity, and an increase in program involvement suggest that the multiservice is reaching more clients with complex behavioral and social needs. Continued integration of these services is important for sustaining client stability while addressing social determinants of health.

Background: With rising concerns about health impacts from climate change and environmental exposures, planetary health approaches are increasingly prominent, considering connections between human health and that of the natural environment. Naturopathy is an holistic traditional medicine system characterised by philosophies and practices rooted in nature that theoretically align with planetary health. However, it is unknown to what extent these philosophies translate into consideration of relevant factors during patient care. This study describes the perceptions and clinical behaviours of the global naturopathic workforce in addressing the health impacts of climate change and environmental pollutants. Methods: A cross-sectional online survey was administered to an international sample of naturopathic practitioners, recruited through communications from World Naturopathic Federation member organisations. The survey utilised the Climate Change Perceptions Scale, and asked participants about their perceptions of the health impacts of climate change and environmental pollutants. The survey also examined participant considerations of factors relating to climate change and environmental pollutants during clinical case assessment and prescribing of treatments. Data were descriptively analysed. Results: Of n=363 naturopathic practitioners who completed the survey, 88.7% agreed climate change is real, of whom the majority were concerned about impacts of climate change on their patients' health (89.1%). Almost all participants agreed that environmental pollutants harm human health (99.7%) and were concerned about impacts on their patients (99.5%). Climate-related health factors such as water intake (74.2%) and food security (72.9%) were frequently considered during patient assessment, while impacts of severe weather events (41.4%) were less commonly considered. Consideration of factors relating to environmental pollutants was more commonly reported, particularly for food quality (83.8%) and domestic/indoor sources of pollutants (73%). When formulating prescriptions, participants reported highly frequent consideration of all climate-related factors (73%-86.8%) and varied consideration of environmental pollutant exposures (54.4%-83.4%). Conclusions: The global naturopathic workforce demonstrates a high level of awareness and engagement with factors relating to health impacts of climate change and environmental pollutants, suggesting alignment with planetary health. While this engagement is evident in clinical behaviour, some gaps between awareness and application suggest a need for greater support to strengthen the naturopathic application of planetary and environmental health.

Youth in the United States are experiencing growing mental health challenges, yet many face barriers to accessing timely, affordable, and stigma-free support. At the same time, artificial intelligence (AI) chatbots have become widely available and are increasingly being used by young people as tools for information seeking, coping, and self-reflection. This brief report explores how youth are engaging with AI chatbots for mental health support, drawing from qualitative interviews conducted in New Jersey. Nine semi-structured interviews were completed with participants ages 19-22. Thematic analysis revealed five core themes: (1) generational change, peer communication, and humor as coping and normalization tools; (2) internal and external barriers to self-recognition and help-seeking; (3) AI chatbots as a safe and accessible first step; (4) AI chatbots as a tool for filling information gaps; and (5) limits of AI chatbots and the preference for human connection. These findings indicate that young people see AI chatbots as private, judgment-free starting points for exploring their emotions and seeking early support. However, they also recognize that these tools cannot replace human connection or professional care. For public health, this presents both challenges and opportunities in utilizing the accessibility of AI chatbots while ensuring ethical design, cultural responsiveness, and protections that safeguard youth privacy and equity.

Background Cancer is a growing public health challenge in low- and middle-income countries, where urbanization, nutritional transition and lifestyle changes contribute to modifiable risk factors. In Mauritania, population-based data on cancer-related nutritional, behavioral and anthropometric risk factors remain limited. Objective To describe the frequency of the main nutritional, behavioral and anthropometric cancer-related risk factors among adults living in the three wilayas of Nouakchott. Methods A cross-sectional study was conducted among 1,000 adults aged 18 years and older in Nouakchott. Data were collected using a standardized questionnaire covering sociodemographic characteristics, dietary habits, physical activity and selected health behaviors. Anthropometric measurements were performed to assess body mass index and abdominal adiposity. Abdominal obesity was defined using sex-specific waist circumference cut-off points recommended by the World Health Organization: [&ge;] 88 cm in women and [&ge;] 102 cm in men. Results were presented as frequencies and proportions, with comparisons by sex, age group and wilaya of residence. Results Women represented 52.0% of participants, and 53.5% were aged 18-34 years. Excess body weight was frequent, with 38.6% overweight and 28.0% obese. Abdominal adiposity was also common, with 58.0% having increased or substantially increased waist circumference and 48.3% having an elevated waist-to-hip ratio. Physical inactivity was reported by 64.7% of participants, and 15.7% were current smokers. Dietary exposures included high red meat consumption in 66.8%, daily refined cereal intake in 67.5%, daily sugar-sweetened beverage consumption in 14.9%, and limited daily fresh fruit consumption in 13.8%. Significant differences were observed by sex for anthropometric indicators, by age for selected dietary habits, and by wilaya for physical activity, smoking and selected dietary behaviors. Conclusion This study shows a high frequency of modifiable cancer-related risk factors among adults in Nouakchott, particularly excess body weight, abdominal adiposity, physical inactivity and unfavorable dietary habits. These findings support the need to strengthen primary prevention strategies targeting nutrition, physical activity and tobacco control in Mauritania.

Strengthening the resilience and inclusivity of primary health care (PHC) systems during crises is critical to achieving equitable access to health care in low-income countries. The COVID-19 pandemic exposed significant weaknesses in PHC systems, highlighting gaps in inclusivity and resilience, particularly for persons with disabilities (PWDs). Although studies have examined PWDs, few have applied systems thinking approaches such as Group Model Building (GMB). This study aimed to develop a resilient and inclusive PHC system to improve access to services and vaccine uptake among PWDs during pandemics. A mixed-methods design incorporating GMB was employed in three phases. First, quantitative and qualitative data were collected to identify barriers and facilitators to PHC access and vaccine uptake. Second, a stakeholder GMB workshop was conducted in Monze to map system dynamics and develop causal loop diagrams. Third, validation and refinement meetings were held, including a final workshop in Lusaka. Findings identified key endogenous system drivers influencing vaccine uptake and access to PHC services and consumables, including financing mechanisms, human resources, outreach services, transport, staff commitment, and availability of accessible information such as Braille materials. These interact through reinforcing and balancing feedback mechanisms. In addition, critical contextual (exogenous) drivers such as political will, health insurance, community gatekeepers, and road networks shape system performance and influence access and service delivery. Strengthening both endogenous system drivers and contextual factors through inclusive strategies, coordinated financing, and supportive governance is essential for building resilient PHC systems that improve equitable access and vaccine uptake among PWDs during health crises. These findings contribute to Universal Health Coverage and equity by showing that strengthening both health systems drivers and contextual drivers is essential to ensure inclusive, accessible, and fair delivery of PHC services for all populations, including persons with disabilities.
