Abstract Epidemiologic research and quantitative risk assessment play a crucial role in transferring fundamental scientific knowledge to policymakers so they can take action to reduce the burden of ambient air pollution. This commentary addresses several challenges in quantitative risk assessment of air pollution that require close attention. The background to this discussion provides a summary of and conclusions from the epidemiological evidence on ambient air pollution and health outcomes accumulated since the 1990s. We focus on identifying relevant exposure-health outcome pairs, the associated concentration-response functions to be applied in a risk assessment, and several caveats in their application. We propose a structured and comprehensive framework for assessing the evidence levels associated with each exposure-health outcome pair within a health impact assessment context. Specific issues regarding the use of global or regional concentration-response functions, their shape, and the range of applicability are discussed.

Abstract Background Placement interventions, characterised by greater availability and more prominent positioning of healthy food products in supermarkets and other food stores, are associated with healthier patterns of purchasing and diet. The WRAPPED intervention study is a natural experiment that aims to evaluate a supermarket placement intervention to improve fruit and vegetable sales, household purchasing and the dietary quality of women and their children. Process evaluation, alongside the evaluation of outcomes, is essential to understand how interventions are implemented, under what circumstances they are effective, and their mechanisms of impact. This study aimed to assess the implementation of the WRAPPED placement intervention. Methods The study adopted a convergent mixed-methods design. Quantitative data extracted from study store planograms (visual representation of stores and product placement) before and after intervention implementation were used to assess the positioning of fresh fruit and vegetables in the first aisle from the front entrance (intervention dose). The availability of fresh fruit and vegetables in each study store was examined from stock-keeping unit (SKU) figures before and after intervention implementation. An intervention implementation survey (IIS) completed with store managers and senior supervisors before and 1- and 6-months post-intervention implementation enabled examination of the context across study stores. Semi-structured interviews with store managers and senior supervisors provided qualitative data about store staff experiences and perceptions of the intervention between 6-months post-intervention implementation. Results The placement intervention was implemented with close adherence to the study protocol. There were marked differences, post-intervention implementation, in the positioning of fresh fruit and vegetables in intervention stores compared with control stores: median distance in intervention stores was 8.0 m (IQR 5.0 to 10.0) compared with 23.8 m (IQR 21.0 to 30.0) in control stores (P

Abstract Background Favorable movement behavior patterns, comprising more physical activity, less sedentary behavior, and sufficient sleep, may promote the maintenance of good quality of life (QoL) with advancing age. The aim of the present study was to investigate whether movement behaviors predict future changes in QoL among community-dwelling older adults over a four-year follow-up. Methods Participants were 75-, 80- and 85-year-old community-dwelling older adults (n = 203) followed up for 4 years. Participants wore thigh- and trunk-mounted accelerometers for 3–7 days at baseline. Proportion of time-use in physical activity, standing and sedentary behavior were assessed based on body posture and movement intensity. Time in bed was determined using an automated algorithm. QoL was assessed during a home interview using the short Older People’s Quality of Life Questionnaire at baseline and follow-up (range 13–65, higher scores indicate higher QoL). Compositional linear regression analysis was used to study whether baseline time-use composition predicts changes in QoL. Results Over the 4-year follow-up, QoL scores decreased by 5% on average. Higher physical activity in relation to the other movement behaviors was associated with increase in QoL over time (βilr 0.94, p = 0.013), but this association attenuated after adding baseline physical function into the model. Sedentary behavior, standing, and time in bed were not associated with changes in QoL. Theoretical reallocation of 30 min of physical activity into sedentary behavior, standing or time in bed was estimated to decrease QoL by 0.5 (CI 95% -0.6 to -0.4), 0.6 (-0.7 to -0.5) and 0.4 (-0.5 to -0.3) points, respectively. Conclusions Theoretical reallocation of physical activity into sedentary behavior, standing, and time in bed was found to be associated with prospective decline in QoL among older adults. Engaging more in physical activity and less in more passive activities may promote better QoL with advancing age.

Abstract This study aims to explore the psychometric properties of the Jordanian version of the Modified Checklist for Autism in Toddlers-Revised (M-Chat-R/F). The Jordanian version of M-CHAT-R/F was administered within the Jordanian context among 134 children aged between 6 and 30 months; 37 were diagnosed with autism spectrum disorder (ASD), and 97 were without ASD. The M-CHAT-R/F consists of the modified Autism Spectrum Screening Questionnaire (ASSQ) and a follow-up model. The results revealed that M-Chat-R/F demonstrates acceptable levels of validity and reliability. The content validity was deemed suitable for the Jordanian environment, and the construct validity showed that items relying on a single factor reached saturation. The results also revealed acceptable levels of reliability, with Pearson correlation coefficients ranging between 0.209 and 0.693, all positive, high, and statistically significant. The Cronbach’s alpha coefficient was 0.870, the sensitivity coefficient was 0.786, and the specificity coefficient was 0.957, indicating the checklist's ability to classify cases of ASD in children. In conclusion, the M-CHAT-R/F is a highly valid and reliable instrument that can effectively classify cases of ASD in children aged between 16 and 30 months. A score of 6 or below on the checklist indicates a high probability of ASD, reaffirming the confidence in the potential of the M-CHAT-R/F checklist for healthcare professionals in the field of child development and autism spectrum disorders. Finally, this study emphasizes that the Jordanian version of M-Chat-R/F is a screening rather than a standardized diagnostic tool for ASD, underscoring the need for further validation.

Abstract Background Workplace violence (WPV) is considered a global public health issue that places physical and mental burdens on healthcare professionals (HCPs). WPV generally negatively affects quality of life (QOL). Purpose This study aimed to determine the prevalence of WPV in HCPs and its association with their QOL in the presence of social support. Methods Cross-sectional, descriptive, correlational research was conducted in medical, surgical, intensive care, and emergency departments in hospitals in Amman. A total of 367 HCPs filled questionnaires designed to evaluate aspects related to WPV, QOL, and social support. Results The prevalence of verbal and physical violence was 83.1 and 23.4%, respectively. Low levels of WPV, moderate to high level of social support, and low to moderate total QOL were noted. Conclusion Verbal violence was more dominant among HCPs. WPV negatively affects most domains of HCPs’ QOL. Social support successfully alleviated the consequences of WPV.

Abstract The COVID-19 pandemic has had varying impacts on different populations around the world. In some developing regions, particularly Africa, the pandemic has not resulted in high mortality rates but has exposed significant deficiencies in healthcare infrastructure. This analysis underscores the urgent need for governments to prioritize substantial investment in healthcare infrastructure development, aiming to strengthen the capacity of African nations to effectively tackle global health crises. The commentary provides specific, actionable recommendations that can empower African governments to better prepare for and respond to future health emergencies.

Abstract Background The World Health Organisation states that newborns should receive colostrum as soon as possible after birth. However, among newborns needing neonatal intensive care, initiation of lactation and access to colostrum might be delayed. At the centre of this study, a tertiary care hospital in Sweden (10,000 deliveries/year), few admitted infants received colostrum within the day of birth, warranting a quality improvement. In order to reduce the time from birth to first colostrum received by infants admitted to the Neonatal Intensive Care Unit (NICU), a new clinical routine including a colostrum-kit, was implemented as standard care in June 2018. The colostrum-kit contained information about hand expression of breastmilk as well as material for collecting, labelling and transporting the colostrum. The kit should be handed to all birthing parents with infants admitted to the NICU. Methods Data on time in minutes from birth to first colostrum administered to the infant (oral mouth care, oral feeding or gavage feeding) was retrieved for all infants born between 1 September 2016 and 31 October 2023, admitted to the NICU within 1h from birth. Infants were divided into four time-cohorts, compared with nonparametric ANOVA. Results The study included 3618 infants born at 22 + 0 – 43 + 0 weeks gestational age, of whom 2814 (78%) had available data on time to colostrum. Median (IQR) time in hours was 35 (20–36) pre-implementations, followed by 18 (7–38), 11 (4–26) and 8 (3–22) in the subsequent follow-up cohorts, p 36 weeks) had a pre-implementation time of 48 (26–80), 46 (23–73), 33 (20–60) and 32 (19–57), that in the last follow-up was reduced to 4 (2–20), 7 (2–29), 9 (2–33) and 9 (4–19). Conclusions Implementing a colostrum-kit for infants admitted to the NICU significantly reduced the time to first colostrum administered to the infant in all gestational ages. The difference between subgroups of gestational age or mode of delivery was reduced. The effect persisted over time.

Abstract Background Non-alcoholic fatty liver disease (NAFLD), characterized by excess liver fat, is common in women with a history of gestational diabetes mellitus (GDM). While breastfeeding improves postpartum lipid levels, its impact on NAFLD in these women is not well studied. We aimed to investigate the relationship between the duration and intensity of breastfeeding and the amount of liver fat and prevalence of NAFLD in women with previous GDM at approximately 1 year postpartum. Methods This prospective cohort study was conducted at a university hospital in Bangkok, Thailand between November 2021 and February 2024. Overall, 130 women who had experienced GDM in their most recent pregnancy were followed up for 1 year postpartum. We collected data on breastfeeding practices and quantified liver fat using controlled attenuation parameters (CAPs) during transient elastography. NAFLD was defined as a CAP of ≥ 302 dB/m. Women were divided into three groups according to the duration and intensity of breastfeeding: group 1 (breastfeeding for

Abstract Background With existing researches identifying an increased rate of long-term conditions (LTCs) among Inflammatory Bowel Disease (IBD) patients, yet there is a lack of exploration into the patterns of comorbidity and prognostic rates for IBD patients with multiple morbidities. Methods The study included 8,305 participants who self-reported having IBD, comprising ulcerative colitis (UC) and Crohn’s disease (CD). Latent class analysis (LCA) was utilized to create optimal categories of LTC combinations for UC and CD patients with additional long-term conditions. Using Cox proportional hazards models, we compared the all-cause mortality rates over a 16-year follow-up among UC and CD patients within different LTC categories, both without LTCs and with the addition of one LTC, the probability of major adverse cardiovascular events (MACE), and the rates of IBD-related surgeries. Results A total of 5,617 participants reported having two or more LTCs, with the LCA method identifying three prevalence categories among CD patients, and four prevalence categories among UC patients. The highest mortality rate among CD patients was found in category 3: (HR 1.789, 95% CI (1.439–2.224)), and the highest rates of MACE were also in category 3: (HR 11.432, 95% CI (9.332–14.005)), with hypertension being the distinguishing characteristic of this category, and the highest rates of IBD-related surgeries being associated with pain in category 1: (HR 1.217, 95% CI (0.983–1.506)). Among UC patients, the highest mortality rate was in category 3: (HR 2.221, 95% CI (1.837–2.684)), with the highest MACE rates found in category 3: (HR 6.422, 95% CI (5.659–7.288)), and the highest rates of IBD-related surgeries being associated with pain, also in category 3: (HR 1.218, 95% CI (1.041–1.425)). Conclusion The rates of adverse health outcomes in IBD patients is closely associated with multimorbidity patterns, underscoring the need to fully consider multimorbidity patterns in the assessment, management, and treatment strategies for IBD.

Abstract Background Electronic cigarettes (e-cigarettes) are gaining popularity globally and becoming popular among young people, including in Nepal. Easy accessibility, appealing ads, and the misconception that e-cigarettes are safer than traditional cigarettes have fueled their rising popularity among university students in Nepal. The lack of comprehensive data on the prevalence and determinants of e-cigarette use among university students in Nepal underscores the urgent need for targeted research in this area. This study aimed to examine the knowledge, attitudes, and practices regarding e-cigarettes, as well as their influencing factors, among undergraduate students at the Institute of Medicine in Kathmandu, Nepal. Methods We conducted a cross-sectional study with 302 undergraduate students. A self-administered questionnaire assessed their knowledge, attitudes, and practices related to e-cigarettes. Descriptive statistics were reported, and chi-square tests and multivariate logistic regression analyses were performed to determine the statistical association among variables using STATA 14. Results The mean age of participants was 21.4 ± 2.1 years. Of the 302 respondents, 214 (70.9%) had heard of e-cigarettes. Among them, 71.5% had good knowledge, 62.2% held supportive attitudes, and 79.0% had never used e-cigarettes. Males were more likely to smoke e-cigarettes than females (AOR: 2.27; 95% CI: 1.01–5.01; p = 0.046). Students with friends who smoke were nearly three times more likely to use e-cigarettes (AOR: 3.00; 95% CI: 1.12–7.99; p = 0.028). Supportive attitudes towards e-cigarettes also doubled the likelihood of smoking them (AOR: 2.10; 95% CI: 1.02–4.35; p = 0.045). Conclusion The study highlights important implications for interventions, policy, and education within Nepal’s medical system. With a notable percentage of students holding supportive attitudes toward e-cigarettes, there is a clear need for targeted behavior change campaigns that educate about the health risks associated with e-cigarettes.

Abstract Background During the COVID-19 pandemic, health literacy was found to be an asset to manage health-related information. The HLS-COVID-Q22 has been developed to measure COVID-19 health literacy. External validation needs to be assessed in different populations to verify the questionnaire’s functioning. The present study aimed to evaluate the psychometric properties of the HLS-COVID-Q22 in a sample of German school principals. Methods The sample consisted of 2187 German school principals who completed the HLS-COVID-Q22 online from April to March 2021. The data was analyzed using Rasch analysis, applying the Partial Credit Model for polytomous data. Dimensionality, item fit statistics and rating scale functioning was tested. Values for item difficulty and person ability as well as reliability indices were computed. Results Unidimensionality could be confirmed. The rating scale categories worked as intended, participants used every rating step category. Generally, item fit was verified. One item showed potential misfit but could remain in the questionnaire as excluding the item did not reduce reliability. A person separation index of 3.41 and person reliability of 0.92 showed excellent differentiation between COVID-19 health literacy levels. Furthermore, the values for item separation of 20.08 and item reliability of 1.0 indicate good construct validity. Conclusions The German version of the HLS-COVID-Q22 appears to be a reliable measurement tool for the target population. Evidence for construct, statistical and fit validity was collected. Future studies need to test additional types of validity like convergent and divergent validity to further evaluate the questionnaire. Moreover, the psychometric properties of the translated versions of the HLS-COVID-Q22 should be compared using Rasch analysis.

Abstract Objective This study aims to examine the relationship and mechanism between sense of self and nonsuicidal self-injury among college students, providing a new theoretical basis for predicting and preventing such behavior. Methods A total of 1350 college students completed the Sense of Self scale, nonsuicidal self-injury questionnaire, frustration scale, and social problem-solving questionnaire. Results (1) Negative Sense of Self predicts frustration, and frustration positively predicts nonsuicidal self-injury. (2) Frustration serves as a partial mediator in the relationship between sense of self and nonsuicidal self-injury. (3) The impulsive-negligent social problem-solving style regulates the first half of the mediation model by influencing the relationship between sense of self and frustration. Conclusion Frustration, mediated by sense of self, increases the risk of nonsuicidal self-injury, and this relationship is moderated by the impulsive-negligent social problem-solving style. Sense of Self is a necessary but not sufficient condition for nonsuicidal self-injury, indirectly influencing such behavior through frustration triggered by stress events.

Abstract Background African Americans with type 2 diabetes experience disparities in their care and diabetes health-related outcomes. Diabetes self-management programs such as Healthy Living with Diabetes (HLWD) are important but do not account for the unique cultural experiences of African Americans. Also, a culturally tailored program focused on addressing sociocultural beliefs and providing race-congruent peer support, Peers LEAD (Peers Supporting Health Literacy, Self-Efficacy, Self-Advocacy, and Adherence) was implemented in two midwestern cities to improve medication adherence but does not include diabetes self-management topics included in HLWD. In an attempt to fill the gaps from both HLWD and Peers LEAD, Peers EXCEL (Peers’ Experience in Communicating and Engaging in Healthy Living) was designed to integrate both programs. Methods Our study explored the perceptions of African American participants and facilitators of the separate HLWD and Peers LEAD programs, on the proposed new Peers EXCEL program using focus groups and interviews. Findings were analyzed by research assistants trained in qualitative research using deductive and inductive open coding approaches. Results Participants appreciated the cultural fit of Peers EXCEL for African American communities which is a feature that was lacking in HLWD. They shared the need to include topics such as the relationships between systemic racism and diabetes. Conclusion Participants’ feedback of Peers EXCEL reveals the importance of including various community members’ perspectives in the design of new diabetes self-management programs tailored for African Americans.

Abstract Background Suboptimal health status (SHS) is an intermediate status between ideal heath and illness, it is characterized by the perception of health complaints, general weakness, decreased immunity and low energy. An increasing number of Chinese middle school students are suffering from psychological symptoms (PS), particularly anxiety and depression. The relationship between SHS and PS is unclear in adolescents. This study aimed to investigate the prevalence of SHS and the correlation between SHS and PS among Chinese middle school students and to identify the SHS-related risk factors from the perspective of public health. Methods A cross-sectional study was conducted with the cluster sampling method among 1955 middle school students in Shantou, China. SHS was assessed by Suboptimal Health Status Questionnaire-25 (SHSQ-25). And the PS of anxiety and depression were assessed with Generalized Anxiety Disorder Scale (GAD-7) and Beck Depression Inventory-II Scale (BDI-II) self-assessment questionnaires. Variate logistic analysis was applied to explore risk factors of SHS. The relationship between SHS and PS among Chinese middle school students was subsequently analyzed. Results Among the 1955 participants, 1904 middle school students were finally included in the analysis, the effective response rate was 97.39%. The prevalence of SHS was 10.3% (197/1904) while the prevalence of anxiety and depression was 30.7% (585/1904) and 34.1% (649/1904), respectively. A strong correlation was identified between SHS and PS among middle school students. With the aggravation of anxiety and depression, the probability of suffering from SHS increased (both P

Abstract Background Prolonged sedentary behavior in pregnant women is reported to be associated with worse health-related indices and pregnancy outcomes. The aim of this study was to identify relevant factors that can be targeted in interventions to reduce sedentary behavior during pregnancy. Methods Of 103,057 pregnancies registered in the Japan Environment and Children’s Study, 83,733 pregnant women were included for analysis after excluding multiple enrollments, nonresponses, and missing outcome data. Data were collected using the International Physical Activity Questionnaire and analyzed using logistic regression models to calculate crude and adjusted odds ratios. Missing data were handled using multiple imputations, and statistical analyses were performed using SAS software. Results Mean sedentary behavior time increased from 5.4 h/day before pregnancy to 5.9 h/day during pregnancy. The percentage of women classified in the high sedentary behavior group increased from 25.6% before pregnancy to 31.2% during pregnancy. Factors associated with high sedentary behavior during pregnancy included longer hours spent watching television and playing video games before pregnancy, higher annual household income, and working status during pregnancy. Possible protective factors against high sedentary behavior included engaging in ≥ 150 min of moderate to vigorous physical activity per week before pregnancy. Conclusions This large-scale cohort study provides valuable insights into sedentary behavior patterns among pregnant women in Japan. To reduce the amount of time engaged in sedentary behavior during pregnancy, the planning and management of time spent watching TV and playing video games as well as establishing exercise habits before pregnancy are recommended.

Abstract Background Sitting time (ST) constitutes a significant aspect of sedentary behavior, and its worldwide escalation raises concerns regarding public health. International guidelines recommend limiting sedentary time and replacing it with physical activity (PA) to reduce the risk of diseases and mortality. This study examines the impact of replacing ST with PA on all-cause, cardiovascular disease (CVD), and cancer mortality in a representative cohort of the population of Spain. Methods We included 30 955 participants aged 15–69 years from two National Health Surveys performed in 2011 and 2017. Data were linked to mortality records as of December 2022. Data on ST, light PA (LPA), and moderate-vigorous PA (MVPA) were collected as part of the International Physical Activity Questionnaire at baseline. Isotemporal substitution analysis from Poisson regression models was used to estimate the relative risk ratio (RR) of replacing ST with LPA or MVPA. Results During a median follow-up of 5.7 years, 957 deaths were reported. The replacement of 1 h per week of ST with 1 h per week of MVPA was significantly associated with a lower risk of all-cause (3.3%), CVD (6.7%), and cancer mortality (3.1%). Similarly, replacing 1 h per week of ST with 1 h per week of LPA was significantly associated with a lower risk of all-cause (1.6%) and cancer mortality (2.1%). Finally, substituting 1 h per week of LPA with 1 h per week of MVPA was significantly associated with a 7.6% lower risk of CVD mortality. Conclusions Substituting one hour per week of ST with an equivalent amount of PA was associated with a lower risk of all-cause, CVD, and cancer mortality.

Abstract Background Safe motherhood programs must include both readiness for complications and childbirth. Birth preparedness and complication readiness (BPCR) is a comprehensive approach that helps resolve delays in deciding to seek care for obstetric problems. Objectives To identify the determinants of BPCR practice among reproductive age group women in Africa. Design Systematic Review and Meta-Analysis. Data sources and methods Preferred Reporting Items for Systematic Reviews and meta-analysis (PRISMA) were followed and databases such as MEDLINE, PubMed, Scopus, Hinari, Google Scholar, and Web of Science were used to find the available studies. Adjusted Odds Ratio (AOR) with 95% Confidence Interval (CI) was used to identify associated factors. I2 statistics, funnel plot, and Egger test were used to assess the studies’ heterogeneity and publication bias. Results In this review, a total of 32 studies with 17,787 sample sizes were included. Knowledge of BPCR (AOR = 2.12, 95% CI: 1.44, 3.13), knowledge of danger signs during pregnancy (AOR = 1.60; 95% CI: 1.37, 1.88), Knowledge of labor and delivery danger signs (AOR = 1.44; 95% CI: 1.28, 1.62), Knowledge of postpartum danger signs (AOR = 1.40; 95% CI: 1.21, 1.63), urban residency (AOR = 1.32; 95% CI: 1.03, 1.70), Antenatal Care follow-up (AOR = AOR = 1.52;95% CI:1.42, 1.63), history of stillbirth (AOR = 1.59; 95% CI: 1.36, 1.86), parity (AOR = 1.76; 95% CI: 1.16, 2.66) and secondary or higher educational status (AOR = 1.51: 95% CI: 1.35, 1.68) were the determinants of BPCR practice. Conclusion BPCR practice among African women of reproductive age has been greatly affected by antenatal care visits, urban residency, knowledge of danger during pregnancy, labor, and postpartum, history of stillbirth, primiparity, and secondary or higher education. Focused interventions that address the identified factors may enhance BPCR practices and maternal health outcomes in Africa.

Abstract Background Racism has been shown to impact the health of Black persons through its influence on health care, including its expression through implicit biases in provider training, attitudes, and behaviours. Less is known about the experiences of racism in contexts outside of the USA, and how race and racism interact with other social locations and systems of discrimination to shape Black patients’ experiences of racism in health care encounters. To help address this gap, this study examined diverse Black individuals’ perceived experiences of, and attitudes towards, anti-Black racism and racial discrimination in Canadian health care, specifically in Montreal, Quebec. Methods This descriptive qualitative study adopted a social constructionist approach. Employing purposive maximal variation and snowball sampling strategies, eligible study participants were: self-identified Black persons aged 18 years and older who lived in Montreal during the COVID-19 pandemic, who could speak English or French, and who were registered with the Quebec medical insurance program. In-depth interviews were conducted, and a Framework Analysis approach guided the systematic exploration and interpretation of data using an intersectionality lens. Results We interviewed 32 participants, the majority of whom were women (59%), university educated (69%), and modestly comfortable financially (41%), but diverse in terms of age (22 to 79 years), country of origin, and self-defined ethnicity. We identified five major themes demonstrating substantial variations in perceived racism in health care that are influenced by unique social locations such as gender identity, age, and immigration history: (1) no perceptions of racism in health care, (2) ambiguous perceptions of racism in health care, (3) perceptions of overt interpersonal racism in health care, (4) perceptions of covert interpersonal racism in health care (including the downplaying of health concerns, stereotyping, and racial microaggressions), and (5) perceptions of systemic racism in health care. Conclusions Perceptions of anti-Black racism and racial discrimination in Canadian health care are complex and may include intra-racial group differences. This study begins to address the dearth of empirical research documenting experiences of anti-Black racism in health care in Quebec, highlighting a continued need for serious consideration of the ways in which racism may manifest in the province, as well as a need for anti-racist advocacy. Advancing racial health equity requires greater sensitivity from providers and decision makers to variations in Black patients’ health care experiences, towards ensuring that they have access to high quality and equitable health care services.

Abstract Background Generating insights into resource demands during outbreaks is an important aspect of pandemic preparedness. The EU PANDEM-2 project used resource modelling to explore the demand profile for key resources during pandemic scenarios. This review aimed to identify public health and healthcare resources needed to respond to pandemic threats and the ranges of parameter values on the use of these resources for pandemic influenza (including the novel influenza A(H1N1)pdm09 pandemic) and the COVID-19 pandemic, to support modelling activities. Methods We conducted a systematic literature review and searched Embase and Medline databases (1995 – June 2023) for articles that included a model, scenario, or simulation of pandemic resources and/or describe resource parameters, for example personal protective equipment (PPE) usage, length of stay (LoS) in intensive care unit (ICU), or vaccine efficacy. Papers with data on resource parameters from all countries were included. Results We identified 2754 articles of which 147 were included in the final review. Forty-six different resource parameters with values related to non-ICU beds (n = 43 articles), ICU beds (n = 57), mechanical ventilation (n = 39), healthcare workers (n = 12), pharmaceuticals (n = 21), PPE (n = 8), vaccines (n = 26), and testing and tracing (n = 19). Differences between resource types related to pandemic influenza and COVID-19 were observed, for example on mechanical ventilation (mostly for COVID-19) and testing & tracing (all for COVID-19). Conclusion This review provides an overview of public health and healthcare resources with associated parameters in the context of pandemic influenza and the COVID-19 pandemic. Providing insight into the ranges of plausible parameter values on the use of public health and healthcare resources improves the accuracy of results of modelling different scenarios, and thus decision-making by policy makers and hospital planners. This review also highlights a scarcity of published data on important public health resources.

Abstract Background There is limited evidence on the economic burden of depression among the older population in Singapore. Objective We aim to evaluate the impact of depression on healthcare expenditure and productivity loss among older adults with chronic diseases in Singapore. Methods Using the data from the Well-being of the Singapore Elderly study (WiSE), a 2011 national representative survey of older adults aged 60 years and above, 2510 respondents were included in this study. The sample comprised 44% male and 56% female respondents with 75% respondents aged between 60 and 74 years old. Healthcare utilisation data was obtained from respondents and healthcare cost was tabulated by multiplying each service unit by the unit cost price. These services include care from polyclinic doctors, private general practitioners (GP), outpatient specialists and inpatient care. We modelled the relationship of healthcare cost and depression using two-part models (probit & generalised linear model - loglink and gamma distribution). Results For total healthcare expenditure, older adults with both depression and chronic diseases were associated with an average annual incremental cost of $7940 (95% CI 1490–14400; p = 0.016), compared to those without these conditions. They were also associated with an average incremental cost of $257 (95% CI 38.7–475; p = 0.021) for primary care. Likewise, in the case of specialist outpatient clinics, they had an average incremental cost of $970 (95% CI 163–1780; p = 0.018). However, for inpatient setting, the average incremental cost of $6180 (95% CI 418–12800; p = 0.066) was not significant. Additionally, older adults with depression and chronic diseases contribute to an annual productivity loss of $676 (95% CI 346–1010; p

Abstract Background Hepatitis C virus (HCV) reinfection following successful treatment threatens the achievement of HCV elimination. The primary aim of this study is to assess reinfection rate three years after sustained virologic response (SVR) in people who inject drugs (PWID) that are on opioid agonist treatment (OAT) who underwent anti-HCV treatment with interferon-free regimens. Methods Observational, non-interventional, prospective, descriptive study carried out in Spanish tertiary public hospitals between 2017 and 2022. Participants comprised 186 adult HCV infected individuals, 85.5% males with a mean age (Standard Deviation, SD) of 50.1 (5.9). All were enrolled in an OAT program at baseline and had attained SVR 12 weeks after therapy completion with an interferon-free treatment. Baseline data were abstracted from medical chart information collected through the routine clinical practice. Results The overall rate of HCV reinfection three years after SVR12 among PWID was 1.2 new cases per 100 person-years of follow-up at a median of 15.9 months. In the subgroup analyses, those with injection drug practice and without a stable housing had higher reinfection rates. Conclusion Although PWID in OAT present a low rate of reinfection by HCV after successful treatment, a closer monitoring in the first year and strengthening inter-consultations with services responsible for monitoring addiction in these patients will be crucial to reduce risky behaviors avoiding HCV reinfection.

Abstract Background To assess students’ use and perception of the initiatives to tackle food insecurity (FI) in a Texas historically black college and university (HBCU). Methods HBCU students > 18 years (288 students). A mixed-methods approach involving an online survey, focus group discussions and key informant interviews were conducted among the students and major stakeholders to evaluate the prevalence of FI, and gain insights into the challenges to accessing, utilizing and effectively implementing food security (FS) initiatives. Results FI affected 63.5% of the participants. The awareness and utilization of the food pantry were 27.9% and 8.1% respectively while for the meal share programs, awareness and utilization were 30.1% and 15.0%, respectively. A significant association was found between FI and the place of residence (p = 0.027). Binary logistic regression model showed that students’ school year was a predictor of food pantry awareness (p

Abstract Background A petroleum leak into the Joint Base Pearl Harbor-Hickam water system on Oahu, Hawaii in November 2021 contaminated the drinking water of approximately 93,000 users, causing many to relocate for months. Perceptions of health and wellbeing were captured using the Centers for Disease Control/Agency for Toxic Substances and Disease Registry (CDC/ATSDR) Assessment of Chemical Exposures (ACE) cross-sectional survey in collaboration with the Hawaii Department of Health (HDOH). Methods Responses from the ACE online survey of community members, businesses, schools, health care and veterinary care organizations during the contamination event, containing quantitative questions and qualitative information from an open text field, were analyzed. Separately, a qualitative key informant questionnaire was administered to community establishments. Thematic content analysis was used to analyze and identify prominent themes from the ACE open text field and the key informant responses that were triangulated by the quantitative data when the themes aligned. Results Six major themes of disruption, communication, trust, stress, support, and ongoing needs were identified. Burdensome logistics from obtaining alternate water, negative financial impacts from relocation or losing business, distrust of information, perceived lack of support from response entities and uncertainty of long-term health impact caused significant disruption, stress and mental health. Individuals reported needing water, shelter, and mental health care while establishments wanted financial reimbursement and a resolution. Conclusions The findings show that environmental disasters have significant disruptive and mental health impacts from stress. Identified themes can inform and improve emergency response and communication strategies and increase trust with community members during and after large chemical exposure events.

Abstract Background Sleep disorders can be harmful to our health and treating them can also be expensive. Due to the widespread occurrence and impact of sleep disorders, it is valuable to investigate and study them from an epidemiological perspective. Therefore, this study aimed to determine the prevalence of sleep disorders among Iranian adults in 2022. Method This is a cross-sectional study that examines the prevalence of sleep disorders and problems in Iranian society. The participants were selected using a mixed sampling approach (utilizing virtual space and cluster sampling). A two-part package was used for evaluating participants sleep problems, which included a demographic profile form and the Holland Sleep Disorders Questionnaire. After collecting the data, appropriate statistical tests in SPSS version 25 were utilized for analysis. Results A total of 6013 questionnaires were fully filled out for this research, with participants answering the specific questions. The participants’ score on sleep disorders was 1.94, which means 44.1% of them suffer from sleep disorders. The results indicated that the prevalence of sleep disorders in this study was as follows: insomnia (35%), parasomnia (35.3%), circadian rhythm sleep disorder (38.4%), hypersomnia and excessive daytime sleepiness (39%), restless leg syndrome and leg movements during sleep (43%), and breathing disorders related to sleep (38.4%). The prevalence of sleep disorders among the study participants demonstrated a significant relationship with most of their demographic variables (P

Abstract Purpose Blood donors are crucial in maintaining the blood supply chain. This study aims to improve the location and distribution of blood donation centers by focusing on two main objectives: minimizing costs and maximizing quality. Minimizing costs includes setting up and transporting blood efficiently while maximizing quality to ensure that blood products are delivered to hospitals promptly and in the right quantities. Methods A multi-objective mathematical model is proposed to address the placement of both fixed and mobile blood donation centers. The first objective focuses on minimizing the costs of setting up centers and transporting blood. The second objective aims to maximize quality by ensuring timely deliveries and meeting hospitals’ blood demand. The model utilizes real-world traffic and blood donation data from urban settings to simulate its effectiveness and applicability in practice. The model uses the $$\varepsilon$$ ε constraint method to optimize both objectives simultaneously. Results The model was tested in various scenarios, optimizing cost and quality separately. The algorithm determined the ideal locations for blood donation centers to meet demand by exploring different options. It also accounted for factors that reduce quality, such as delayed deliveries and product returns, and showed that these issues could be minimized. Conclusion This study highlights the need to balance cost and quality when determining the locations of blood donation centers. Using the $$\varepsilon$$ ε constraint method, the model successfully optimized both objectives, offering valuable insights for improving the efficiency and effectiveness of blood donation operations.

Abstract Background The global prevalence of obesity is increasing not only in adults but also in children and adolescents. In addition to the role of genetic and biological factors, policies such as the need for quarantine during the coronavirus epidemic and the family’s behavioral and socioeconomic status in causing obesity cannot be ignored. The current research aimed to investigate the effect of virtual education programs on the health responsibility of overweight students during the outbreak of the Coronavirus. Methods This was a semi-experimental study with a pre-test-post-test design and a randomized control group, which was conducted in three stages)pre-intervention, intervention, and post-intervention) during 2021-22 in Tehran Province, Iran. The samples were 60 adolescent girls aged 12–18 with a body mass index higher than 25 and placed in two test and control groups through random cluster sampling. Data was collected using the demographic information profile and the 12-item health responsibility questionnaire from HPLPII. The intervention was implemented as 6 virtual training sessions of 1.5 h for the test group. After 1.5 months, BMI was measured and a post-test was done. SPSS version 22 software was used for data analysis. Results There was no significant change in the BMI of students after the intervention in the control group (p = 0.476), but it decreased significantly in the test group (p

Abstract Background Studies have emphasised the adverse effects of poor sleep on human health, however, the correlation between sleep abnormalities and hypothyroidism remains unclear. This study evaluated whether sleep abnormalities may be related to increased prevalence of hypothyroidism in general US adults. Methods: In total, 9016 adults who participated in the National Health and Nutrition Examination Survey from 2007 to 2012 were analysed. A standardised questionnaire was used to collect data regarding sleep duration, self-reported trouble sleeping and sleep disorders. Values were assigned to the three aforementioned sleep factors, resulting in an overall sleep score of 0–3. The sleep patterns were divided into healthy sleep pattern (overall sleep score = 3), intermediate sleep pattern (overall sleep score = 2) and poor sleep pattern (overall sleep score = 0 or 1) according to a former study. Hypothyroidism was defined as thyroid-stimulating hormone (TSH) levels > 5.6 mIU/mL or the need to take thyroid hormones. Multivariable logistic regression analysis was performed to assess the relationship between sleep abnormalities and hypothyroidism. Results: The overall prevalence of hypothyroidism was 8.0% among the 9016 participants. Self-reported trouble sleeping (odds ratio [OR] = 1.38, 95% CI: 1.14–1.68, p = 0.001) and sleep disorders (OR = 1.40, 95% CI: 1.06–1.86, p = 0.0196) were associated with increased prevalence of hypothyroidism. Neither short sleep duration (OR = 0.99, 95% CI: 0.82–1.19) nor long sleep duration (OR = 0.98, 95% CI: 0.61–1.58) was significantly associated with hypothyroidism. Moreover, poor sleep pattern was significantly associated with increased prevalence of hypothyroidism (OR = 1.30, 95% CI: 1.03–1.66, p = 0.0301). Conclusions: Both trouble sleeping and sleep disorders were associated with increased prevalence of hypothyroidism.

Abstract Background There is a vicious cycle between unemployment and mental health issues. Unemployed individuals with mental health issues require individualized support at multiple levels in order to promote their mental health, and obtain and retain employment. The 3for1-intervention program aims to provide such support with three components (short-term psychotherapy, job coaching based on the Individual Placement and Support approach, and peer support). This study protocol outlines how the effectiveness of this three-component intervention program in terms of re-employment, mental health, and psychosocial outcomes will be evaluated. Methods The 3for1-intervention program will be evaluated with a non-randomized controlled trial design in a multi-center study. 500 eligible participants aged between 18 and 60 years from six job centers in Southern Germany will be allocated to a control group or an intervention group. Allocation is time-based, with the control group being recruited first, followed by recruitment of the intervention group. The control group will receive treatment as usual, whereas the intervention group will receive treatment as usual as well as access to the three intervention components over a period of 12 months. Assessment will be conducted at baseline (t0), and 12 (t1) and 18 (t3) months later. The primary outcome will be the proportion of participants who are in employment subject to social insurance contributions at t1. Differences between control and intervention group will be tested with logistic regression analysis, controlling for relevant covariates. Analyses of secondary outcomes will relate to group differences regarding re-employment, health and well-being, social integration, help-seeking, and self-stigma at t1 and t2, applying logistic regression analysis or analysis of covariance. Additionally, usage of health services will be measured to evaluate the intervention program’s cost effectiveness. Discussion The 3for1-intervention aims to improve employability and mental health outcomes of a vulnerable population with high need for assistance. Improvements for this population would benefit the German welfare state as well. This study could provide valuable insights into the feasibility, implementation, and sustainability of this individualized, multi-level support program within German job centers. Trial registration This trial is registered with the German Clinical Trials Register: DRKS00029002 (registered on 11 May 2022).

Abstract Objective Information regarding the relationship between epilepsy and vitamin K1 remains unclear. We aimed to assess the association between dietary vitamin K1 intake and epilepsy. Methods Data was obtained from the National Health and Nutrition Examination Survey (NHANES) conducted from 2013 to 2018. The study enrolled participants aged ≥ 18 years that provided complete information on their dietary vitamin K1 intake and epilepsy status. Weighted multivariable regression and subgroup analyses were performed to detect the association between dietary vitamin K1 intake and epilepsy. Results In total, 10 137 participants (mean age, 48 years) were enrolled. Among them, 84 (0.83%) participants were identified as having epilepsy, whereas 10 053 (99.17%) were included in the non-epilepsy group, with an average dietary vitamin K1 intake of 67.2 ± 6.9 and 105.5 ± 1.5 µg/d, respectively. Each unit (10 µg/d) increase in vitamin K1 intake was associated with a 7% decrease in the odds of epilepsy (odds ratio = 0.93, 95% confidence interval: 0.88–0.98, p = 0.011). Multivariate logistic regression analysis revealed that participants in the higher quartile had lower odds of epilepsy than those in the first quartile of vitamin K1 intake. Subgroup analysis showed a stable and consistent inverse association between dietary vitamin K1 intake and epilepsy. Conclusion Higher dietary vitamin K1 intake was associated with lower incidence of epilepsy. Our study did not establish a cause-and-effect relationship. Further large-scale prospective studies and randomized trials are warranted to confirm our findings.

Abstract Background The active travel concept has gained recognition as an effective method to enhance physical activity in children’s everyday mobility. Yet, there is a notable gap of quantitative evidence on its direct impacts, especially regarding physiological outcomes that can concretely demonstrate its influences on physical intensity and overall health of children. Methods This study investigates the effects of active travel on children, focusing on trip-level physiological responses, specifically heart rate. Through a mixed survey design, we obtained a repeated-measures dataset from a cohort of 73 children (average age 13) across three Austrian secondary schools, each observed for 7 days. By applying mixed effects modelling approach, both fixed and random effects to children’s heart rates were explored. Results According to results from developed mixed linear models (maximum R 2 = 0.22), it revealed a significant positive association between active travel mode(s) engagement and heightened physiological responses (Low, Medium and High active level of trip compare to None: β = 1.81, 5.01 and 8.34, t-value = 4.70, 10.29 and 21.34), indicating that increased usage of active travel modes led to elevated heart rate values. Additionally, subjective perceptions also played an important role in influencing children’s physiological responses. Feelings of exhausted, anxiety, and stress contributing to a higher heart rate (β = 14.79, 16.69 and 1.99, t-value = 20.42, 5.67 and 3.0), while unhappiness was associated with a lower heart rate (β = -5.96, t-value = -14.62). Effects of social interactions were also found during the trip. The presence of adults was associated with a calming effect (β = -1.92, t-value = -5.72), whereas solo travel resulted in lower heart rate compared to travel with peers (β = -1.95, t-value = -6.59). Conclusion Our article innovatively employs mixed survey methods and heart rate data to quantitatively demonstrate the positive association between engagement in active travel modes and heightened physiological responses in children, elucidating the intricate interplay of subjective perceptions and social interactions during trips, thus offering valuable insights into the health implications of active travel at a trip level. Future research will keep on leveraging survey and experimental methods.

Abstract Road crash injuries are significant public health issues in many low-and middle-income countries. Every year more than 1.35 million people lose their lives due to road crashes, making it one of the leading causes of death worldwide. In 2021, 1.19 million road traffic deaths occurred worldwide. Globally, India accounts for the second-largest number of fatal road traffic crashes. Riders in the age range of 18–25 years contribute to 41.4% of India’s total road crash victims. An in-depth understanding of the current traffic density, violations, and behaviours of young riders is essential for enforcement agencies, in particular, the traffic police personnel. Their perspective is relevant as they have a unique position to judge and evaluate the riding behaviours and the efficiency of the existing intervention programmes. Furthermore, their suggestions can be highly effective in developing evidence-based risk reduction programmes. The present study was conducted in Manipal, which is a locality of Udupi district in Karnataka province of Southwestern India. Seventeen in-depth interviews were conducted from October 2018 to January 2019 among traffic police personnel. Thematic analysis was done using ATLAS.ti 8 software to identify, analyse, and report themes within the data. Respondents revealed that in recent times Manipal roads have become unsafe for young riders. Factors such as speeding, using a mobile phone while riding, reckless riding, and overtaking from the wrong side were the main reasons for road traffic crashes. Interventions like the installation of traffic barricades, closed-circuit television cameras, speed breakers, and signboards at the crash hotspots, together with strict enforcement of traffic laws, were suggested by the respondents to reduce crashes. The study findings highlight the importance of traffic police personnel’s views in understanding the various determinants for road crashes observed among young riders. Future research can be taken up in other settings with broader age group involvement for the target population. There is a need to establish a coordination committee that can locally organize awareness programmes involving all the stakeholders on road safety to increase the level of risk perception and reduce crashes.

Abstract Background Previous studies have yielded inconsistent findings regarding the association between age at menopause and bone health, with limited exploration of potential mediating factors, particularly in the less-developed muti-ethnic regions of China. Our objective was to analyze the association between age at menopause and bone health among postmenopausal women in southwest China, while also examining the mediating effect of body mass index (BMI) and the moderating effect of years since menopause on this association. Methods and results The analysis included a total of 15,352 naturally postmenopausal women obtained from the baseline data of the China Multi-Ethnic Cohort (CMEC) Study. Multiple linear regression was used for multivariate analysis. Mediation analysis was conducted to examine the mediating role of BMI in the association between age at menopause and bone health. A significant positive association was observed between age at menopause and bone health index (Quantitative ultrasound index, QUI). Specifically, with each year’s delay in age at menopause, there was an increase of 0.260 (95% confidence interval (CI): 0.152–0.368) in QUI. Notably, women with later menopause (menopausal age ≥ 53 years) exhibited a higher QUI (β: 2.684, 95%CI: 1.503–3.865). Additionally, BMI partially mediated the relationship between age at menopause and QUI, accounting for 9.0% of the total effect, with an indirect effect coefficient β(95%CI) was 0.023(0.014, 0.032). Besides, it is worth mentioning that years since menopause moderated the association between age at menopause and bone health as well as the mediating effect of BMI. Conclusion Naturally postmenopausal women with a later age at menopause demonstrate enhanced bone health. Maintaining a moderately high BMI, without progressing to overweight or obesity, may provide health benefits for postmenopausal women, especially for those with a longer duration since menopause.

Abstract Background Antenatal care (ANC) plays a crucial role in ensuring maternal and child safety and reducing adverse delivery outcomes. This study aimed to analyze the association between the quality of ANC and the occurrence of preterm birth and low birth weight in a sample of the population from 16 regions in 8 provinces in China. Methods Data from all closed cases of pregnant women and newborns reported in the Maternal and Child Health Monitoring System from January 1, 2018, to December 31, 2018, in 16 monitoring regions across 8 provinces in China were collected and included in the analysis, resulting in a total of 49,084 pregnant women and 49,026 newborns. Results The mean number of ANC visits was 6.95 ± 3.45. By percentage, 78.79% of the women received ANC examinations at least five times. The percentage of normative ANC examinations and the percentage of qualified ANC examinations was 30.98% and 8.0% respectively. The gestational age(χ2 = 229.305, p

Abstract The present study explores the prevalence and socio-economic demographic factors affecting childhood illnesses. Diarrhoea, fever and ARI among under-five children in the North -East states of India using NFHS-5 data Kids file. Results showed that diarrhoea, ARI, and fever among the northeastern states were highest in Meghalaya.For diarrhoea Sikkim has the highest prevalence for children within 6 months while Meghalaya has the highest prevalence in the age groups 6- 12 months and 1- 2 years old children and Arunachal Pradesh has the highest rate in the age group 2- 5 years old children. Meghalaya stands out with the highest prevalence of fever and ARI in all age groups. Compared to Sikkim, the state of Meghalaya had more diarrhoea, ARI and fever, and it was statistically highly significant. However, Tripura and Assam had significantly higher odds of having fever and ARI than Sikkim. There is an association between diarrhoea, fever, and ARI and factors such as the age of the child and caregiver, the wealth status of the household, the quality of sanitation facilities, methods of stool disposal, and the caregiver's educational level.

Abstract Purpose To explore the worldwide, regional, and country-specific burden of early-onset colorectal cancer (EO-CRC) and identify its associated risk factors between 1990 and 2021, and to project its incidence and mortality rates for 2036. Methods We acquired data on EO-CRC categorized by gender, socio-demographic index (SDI), and risk factors based on the Global Burden of Disease (GBD) Study 2021. Joinpoint regression analysis was utilized to explore the variation in disease burden. The autoregressive integrated moving average (ARIMA) model was performed to forecast the disease burden up to 2036. Results Globally, the incidence rate, prevalence rate, mortality rate, and disability-adjusted life years (DALYs) rate of EO-CRC were estimated at 5.37 (95%UI: 4.91 to 5.86)/100,000, 34 (95%UI: 30.96 to 37.35)/100,000, 2.01 (95%UI: 1.84 to 2.19)/100,000, and 101.37 (95%: 92.85 to 110.18)/100,000 in 2021. The prevalence and incidence rates of EO-CRC showed an ascending trajectory, whilst the DALYs and mortality rates demonstrated a downward trajectory between 1990 to 2021. The high-middle SDI regions and East Asia exhibited the highest EO-CRC burden among the five SDI regions and 21 GBD regions respectively. A low-whole-grains diet was the chief risk factor contributing to EO-CRC. It was predicted that the age-standardized rate (ASR) of EO-CRC incidence would increase by 5.56%, while the ASR of mortality would decrease by 13.9% globally until 2036. Conclusion The current and future global burden of EO-CRC is heavy and varies significantly across different regions and countries.

Abstract Background We examined the associations between screen time and adolescent obesity and the associations of reallocating screen time to other activities using isotemporal substitution models. Understanding the association between screen time and obesity may provide additional insights into effective obesity prevention strategies in adolescents. Methods We conducted a cross-sectional analysis of 5,180 adolescents (4th and 7th grade students) from the Korean Children and Youth Panel Survey 2018. Participants reported their height, weight, and average time spent watching television, using computer, using smartphone, and other after-school activities. Obesity was defined as BMI-for-age and -sex ≥ 95th percentile based on the 2017 Korean National Growth Charts. We performed multivariable logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the associations between screen time and obesity prevalence, adjusting for potential confounders. Results Prolonged smartphone use (≥ 180 vs.

Abstract Objective The objective of this study was to delineate the association between serum uric acid (UA) levels and Muscle Quality Index (MQI), assessing muscle strength relative to mass, in adults aged 20 to 59 years. Methods Utilizing data from the National Health and Nutrition Examination Survey (NHANES) 2011–2014, this study examined the association between UA levels and MQI—a ratio of muscle strength to mass. Weighted linear models, adjusted for potential confounders, assessed the relationship, with a generalized additive model (GAM) probing for non-linear patterns. Subgroup analyses and interaction effects were conducted using weighted linear regression across diverse demographic and clinical groups to ensure the robustness and reliability of our findings. Results Among 5,277 participants, a significant inverse association was observed between UA levels and MQI, with a 0.08 decrease in MQI per 1 mg/dL increase in UA (95% CI: -0.11 to -0.06, p

Abstract Background Rural communities in low- and middle-income countries, such as The Gambia, often experience water insecurity periodically due to climate drivers such as heavy rainfall and reduced rainfall, as well as non-climate drivers such as infrastructural issues and seasonal workloads. When facing these challenges households use a variety of coping mechanisms that could pose a risk to health. We aimed to understand the drivers of water insecurity (climate and non-climate), the behavioural responses to water insecurity and the risks these responses pose to the health of communities in rural Gambia and map these findings onto a conceptual framework. Methods We interviewed 46 participants using multiple qualitative methods. This included in-depth interviews and transect walks. A subset of 27 participants took part in three participatory pile-sorting activities. In these activities participants were asked to rank water-related activities, intrahousehold prioritisation of water, and the coping strategies utilised when facing water insecurity. Results Multiple strategies were identified that people used to cope with water shortages, including: reductions in hygiene, changes to food consumption, and storing water for long periods. Many of these could inadvertently introduce risks for health. For example, limiting handwashing increases the risk of water-washed diseases. Deprioritising cooking foods such as millet, which is a nutrient-dense staple food, due to the high water requirements during preparation, could impact nutritional status. Additionally, storing water for long periods could erode water quality. Social factors appeared to play an important role in the prioritisation of domestic water-use when faced with water shortages. For example, face-washing was often maintained for social reasons. Health and religion were also key influencing factors. People often tried to protect children from the effects of water insecurity, particularly school-aged children, but given the communal nature of many activities this was not always possible. Many people associated water insecurity with poor health. Conclusions To reduce the risks to health, interventions need to address the drivers of water insecurity to reduce the need for these risky coping behaviours. In the short term, the promotion of behavioural adaptations that can help buffer health risks, such as water treatment, may be beneficial.

Abstract Introduction A proper self-management and therapy process, and the involvement of patients and their carers in this process, influences the effectiveness of T1DM therapy. The responsibility for the self-management process lies with children and adolescents with T1DM, as well as their parents and other carers. Aims The aim of this study was to assess the level of teachers’ knowledge of the principles of the treatment and self-management of T1DM in children and to demonstrate the influence of various factors influencing teachers’ knowledge. Materials and methods A cross-sectional survey was conducted among the teachers in the Pomeranian Voivodeship. The first part of the survey contained questions on sociodemographic data, the second part contained questions on personal attitudes towards a student with T1DM, and the third part contained twenty-nine questions assessing the basic knowledge of the self-management and treatment principles of T1DM. Results Tests were conducted with 698 (86.4%) female teachers and 110 (13.6%) male teachers. The median (25thQ ÷ 75thQ) score of the test on the teachers' knowledge was 20 (18 ÷ 21) points, with a maximum of 29 and a minimum of 0 points. Male teachers, aged between 26–40 years, with 6–10 years of seniority, working in rural areas, having a person with T1DM in their immediate environment or having a student with T1DM in their class had a higher knowledge level. Teachers who worked in schools where no nurse was employed and those who had not completed specific training on the principles of caring for a child with T1DM at school had a lower level of knowledge. Conclusions 1. Knowledge of teachers is insufficient to ensure safe stay at school for a child with T1DM. 2. The ongoing training of teachers on the principles of the self-management and treatment of T1DM is necessary to improve and increase the safety of children and adolescents with T1DM in school units. 3. There is a need to improve the quality of health care for children with T1DM in the learning environment by increasing the number of school nurses and improving their knowledge, and by the ongoing training of teachers and other staff in school units. 4. Detailed care plans should be developed for children with T1DM, adapted to the school conditions.

Abstract Background Tuberculosis (TB) remains a major global health threat. Despite ongoing efforts to control and eradicate TB, various factors including socioeconomic issues, policy modifications, and unexpected public health crises like COVID-19 pandemic have posed new obstacles to achieving TB elimination. This study aims to analyze the changes in global tuberculosis burden over the past 32 years, and provide scientific support for global initiatives targeting the eradication of TB in the post-pandemic period. Methods The data for this study were obtained from the Global Burden of Disease (GBD) 2021 database, with age-standardized incidence rate (ASIR), prevalence rate (ASPR), mortality rate (ASDR), and disability-adjusted life years (DALYs) as the primary assessment indicators. Dynamic changes in the TB burden were analyzed by estimating the annual percentage changes (EAPCs). The attributable ratios of six main risk factors to TB burden were calculated, and the correlation between the Socio-Demographic Index (SDI) and the TB burden was analyzed using Pearson correlation tests. Results The global TB incidence decreased from 8.6 million cases in 1990 to 8.4 million cases in 2021, with a corresponding decline in deaths. However, the TB burden remains higher among men than women. The highest incidence and mortality rates were observed in the age group of 15–69 years, with a notable gender disparity, especially in Eastern Europe. These rates were generally elevated in low-income and lower-middle-income regions, with significantly higher Age-Standardized Incidence Rates and Age-Standardized Death Rates in males compared to females. A significant negative correlation was found between SDI values and TB burden. Analyzing risk factors from the Global Burden of Disease study, it was determined that globally, dietary risks, high body-mass index, high fasting plasma glucose, low physical activity, tobacco, and alcohol use were the main contributors to TB age-standardized Disability-Adjusted Life Years, with tobacco and alcohol use having the most significant impact. Analysis of risk factors suggests that tailored public health interventions for specific genders and regions can effectively lessen the TB burden.

Abstract Background Women from areas of social deprivation and minority ethnic groups are more likely to experience poor physical health and have higher rates of mental health problems relative to women from less socially disadvantaged groups. However, very little research has examined this in relation to perinatal anxiety. The current study aims to determine prevalence, risk factors and desire for treatment for perinatal anxiety in three regions of the UK with diverse regional characteristics. Methods Women completed measures of anxiety in early, mid-, late-pregnancy and postpartum. Participants were included from three regions of the UK: Region 1 = North East England & North Cumbria n = 512; Region 2 = London North Thames n = 665; Region 3 = West Midlands n = 705. Results Prevalence of perinatal anxiety was lower in Region 1 (OR 0.63 95% CI 0.45 to 0.89) and Region 2 (OR 0.72 95% CI 0.52 to 0.98) relative to Region 3. Analysis showed the effect of neighbourhood socioeconomic deprivation on perinatal anxiety differed by region. In more affluent regions, living in a deprived neighbourhood had a greater impact on perinatal anxiety than living in a deprived neighbourhood in a deprived region. Other factors associated with risk of anxiety in the perinatal period included physical health problems and identifying as being from ‘mixed or multiple’ ethnic groups. Conclusions Neighbourhood deprivation relative to regional deprivation is a better predictor of perinatal anxiety than either regional deprivation or neighbourhood deprivation alone. Women of mixed ethnic backgrounds and women with physical health problems may warrant more attention in terms of screening and support for perinatal anxiety. Self-reported desire for treatment was found to be low.

Abstract Background Considering the significant growth in India’s aging population, it is imperative to identify factors associated with frailty among older Indians. This study examined the association between sleep quality, sleep duration, and physical frailty among older adults in India. Moreover, we examined whether the associations between sleep quality, sleep duration, and physical frailty varied by gender. Methods In this secondary analysis, we used data from the 2015 wave 2 of the Study on Global Aging and Adult Health (WHO-SAGE) in India, comprising a sample of 6,512 older adults aged 50 years and above. Pre-frailty and frailty were assessed using the modified version of the frailty phenotype developed by Fried and colleagues. Sleep was assessed by self-reported quality and duration. Multinomial and multivariable logistic regression models were used to examine the associations between sleep quality, sleep duration, and physical frailty (including its components), as well as to explore the moderating effect of gender. Results 66.8% of older Indians were pre-frail, while 25.2% were frail. Relative to those with good sleep quality, older adults with poor sleep quality had significantly higher odds of frailty [AOR: 2.79; CI: 1.37–5.66]. Compared to those receiving the recommended age-appropriate 7–8 h of sleep, older adults sleeping ≥ 9 h reported a significantly lower likelihood of both pre-frailty [AOR: 0.73; CI: 0.57–0.93] and frailty [AOR: 0.68; CI: 0.51–0.91]. Analysis of specific components of frailty showed that older adults with long sleep had lower odds of exhaustion [AOR: 0.86; CI: 0.73–1.00] compared to those with age-appropriate sleep duration. Moreover, frailty was more pronounced in older men with poor sleep quality and short sleep duration (

Abstract Background The importance of physical education in higher education is widely recognized, as it improves not only exercise attitudes and motor skills but also physical fitness, social skills, and academic performance. However, physical education courses in Chinese colleges and universities face various constraints, such as a shortage of teachers, limited teaching methods, and insufficient resources, resulting in low student motor skills, negative attitudes toward sports, and low participation rates. This study explores the effectiveness of a blended learning model, which integrates traditional face-to-face instruction with online learning components, in improving university students’ exercise attitudes and basketball skills. Methods The research was conducted in 2022 at Luoyang Normal University in China, utilizing a cluster randomized controlled trial (CRCT) with 78 healthy first-year university students. Participants were randomly assigned to either the experimental group (blended learning) or the control group (traditional learning), and the intervention lasted 16 weeks. Exercise attitudes were assessed via the Exercise Attitude Scale, whereas basketball skills were evaluated via set shot and half-court dribbling and shooting tests. Results Both instructional models improved students’ exercise attitudes and basketball skills; however, the blended learning model demonstrated significantly superior outcomes. Effect sizes (d) ranging from 0.57 to 1.92 indicated that the experimental group showed greater improvements in behavior attitude, target attitude, behavior cognition, behavior intention, emotional experience, behavior control, and subjective standards. In basketball skills, the experimental group outperformed the control group in set shots (d = 0.56) and half-court dribbling and shooting (d = 0.46). Conclusion Compared with traditional methods, blended learning significantly enhances university students’ exercise attitudes and basketball skills. Future research should explore the long-term effects and underlying mechanisms of blended learning in physical education, involving larger and more diverse samples to validate these findings.

Abstract Background During the COVID-19 pandemic, hospitals implemented visitor restrictions to curtail the spread of the virus. The study aims to understand the perspectives of hospitalized patients and their family visitors on visitation restrictions and the factors influencing their willingness to adhere to these restrictions. Methods This cross-sectional survey invited 1,200 participants, with 1,032 valid responses received, including 460 hospitalized patients and 572 family visitors. Results The survey indicated that 88.91% of hospitalized patients and 93.00% of family visitors complied and adhered to the visitor restrictions. The predominant mode of communication was via phone (77.62%), with emotional support (56.40%) recognized as the primary purpose of visitation. Visitor restrictions significantly affected hospitalized patients, with 51.65% reporting feelings of loneliness and 42.44% reporting anxiety. After adjusting for age, gender, and other factors, hospitalized patients‘ willingness to follow visitation restrictions was linked to their awareness of the restrictions (odds ratio [OR] = 0.20, 95% confidence interval [CI]: 0.09–0.44) and their desire to protect (OR = 0.32, 95% CI: 0.14–0.76). Family members’ willingness to follow the restrictions was related to their awareness of them (OR = 0.34, 95% CI: 0.12–0.95) and how well they communicated (OR = 0.23, 95% CI: 0.09–0.58). Conclusions Participants generally followed visitation restrictions, but these measures negatively impacted the psychological and social well-being of patients and their families, leading to increased feelings of loneliness and anxiety. Healthcare providers, hospital administrators, and policymakers should acknowledge the complex effects of these restrictions and focus on improving patient experiences in the future.

Abstract Background Gallbladder cancer is a major health concern in China, and awareness of the associated incidence and mortality rates is particularly important given the aging population. Objective To determine trends in gallbladder cancer incidence and mortality rates over 12 years and quantitatively analyze the influence of demographic factors on these rates in China. Methods We performed a retrospective study of 98,860 Chinese citizens using the Chinese Cancer Registry, a national database. Gallbladder cancer incidence and mortality data pertaining to patients treated between 2005 and 2017 were collected. Joinpoint regression models were used to estimate the annual percentage change (APC) and average APC (AAPC). We used age-period-cohort analyses and decomposition methods to investigate differing trends in incidence and mortality. Results The age-standardized gallbladder cancer incidence and mortality rates in China trended downward between 2005 and 2017, with AAPCs of -2.023% and -1.603%, respectively. Coefficients of age effect for incidence rate increased with age up to 70 years and peaked at 70–79 years, while coefficients of age effect for the mortality rate showed a consistent increase with age. Both coefficients of period for incidence and mortality rates increased in more recent periods; in terms of the cohort effect, coefficients of cohort for rates generally decreased in later birth years but showed a partial rise between 1982 and 1996. The crude incidence rates of gallbladder cancer according to demographic and non-demographic factors were 626.09% and -526.09% respectively (366.23% and -266.23% among men, and 6068.93% and -5968.93% among women, respectively). The rates were 543.01% and -443.01%, respectively, in urban areas and were 68.22% and 31.78%, respectively, in rural areas. The mortality rates according to demographic and non-demographic factors were -495.93% and 595.93%, respectively (-1763.10% and -1863.10% for men and -270.56% and -370.56% for women, respectively). These rates were -930.33% and 1030.33%, respectively, in urban areas and were 101.48% and -1.48%, respectively, in rural areas. Conclusions The overall standardized gallbladder cancer incidence and mortality rates in China are trending downward, but not sufficiently so. Proper living and eating habits should be encouraged while exploring the establishment of long-term, standardized gallbladder cancer screening programs.

Abstract Background Adverse Childhood Experiences (ACEs) have been implicated in the development of body pain, yet research on their impact on body pain and its progression remains scarce. This study aimed to examine the associations between ACEs and the presence and areas of body pain, as well as their developmental trajectories among middle-aged and older Chinese adults. Methods We included participants aged 45 years and above from the China Health and Retirement Longitudinal Study (CHARLS) conducted between 2011 and 2018. Retrospective data on ACEs and pain sites were collected with questionnaires. The presence of pain at different body sites was categorized into three areas: head & neck, trunk, and limbs. ACEs consisted of ten types of adverse experiences and were cumulatively scored. For the cross-sectional analysis (2011), logistic regressions were performed to estimate the associations between ACEs and pain presence in specific areas. In the longitudinal analysis (2011–2018), we further applied group-based trajectory modelling (GBTM) to determine the developmental trajectories of body pain. Multinomial logistic regressions were then conducted to estimate the associations between ACEs and pain trajectories. Results In the cross-sectional analysis (n = 8157), ACEs were positively associated with the presence of pain in the head & neck (odds ratio [OR] = 3.55, 95% confidence intervals [CI] = 2.37–4.74), trunk (OR = 3.28, 95% CI = 2.47–4.34), and limbs areas (OR = 2.30, 95% CI = 1.77-3.00) compared to no ACEs. These associations varied by sex and residence. In the longitudinal analysis (n = 5188), GBTM identified three developmental trajectories of body pain (n = 9521): high-increasing (7.44%), low-moderate (33.67%) and maintained-low trajectories (58.89%) trajectories. Compared to participants without ACEs, individuals had three ACEs and 4 or more ACEs were consistently associated with low-moderate (three ACEs: OR = 2.26, 95% CI = 1.81–2.83, four or more ACEs: OR = 3.11, 95% CI = 2.51–3.87) and high-increasing (three ACEs: OR = 3.28, 95% CI = 2.03–5.30, four or more ACEs: OR = 6.78, 95% CI = 4.30-10.68) body pain trajectories across sexes and residence. Conclusion This study highlighted the significant association between ACEs and body pain among middle-aged and older Chinese, emphasizing the importance of preventing or mitigating ACEs as a strategy for the prevention and management of body pain.

Abstract Background Epidemiological studies investigating the association between flavonoid intake and bone mineral density (BMD) draw inconsistent conclusions. Our study aims to investigate the association between flavonoid intake and BMD and osteoporosis and the mediating role of composite dietary antioxidant index (CDAI) in their relationship using data from the National Health and Nutrition Examination Survey (NHANES). Methods The study assessed the relationship between flavonoid intake and femur BMD and osteoporosis in 10,225 individuals from NHANES 2007–2010 and 2017–2018. Multivariable linear regression analyses were used to detect the association between flavonoid intake and femur BMD in adult Americans. Restricted cubic splines (RCS) were used to examine the nonlinear relationship between flavonoid intake and their subclasses and osteoporosis risk in individuals 20 years or older. We explored the mediating role of CDAI in the association between flavonoid intake and BMD. Results In fully adjusted multivariable regression analyses, compared with people in the first quartile, people in the fourth quartile of total flavonoid intake have a higher BMD at total femur (0.013, 95% CI: 0.004, 0.022, P = 0.001), femur neck (0.010, 95% CI: 0.004, 0.017, P = 0.001), trochanter (0.010, 95% CI: 0.004, 0.017, P = 0.001), and intertrochanter (0.012, 95% CI: 0.003, 0.020, P = 0.006). The positive relationship between flavonoid intake and femur BMD was present in both sexes. Furthermore, we found that people in the fourth quartile of total flavonoid intake have a lower risk of osteoporosis compared with the first quartile (OR = 0.686, 95% CI: 0.528–0.890, P = 0.005). RCS found a linear inverse relationship between total flavonoid intake and osteoporosis in individuals ≥ 20 years (Overall P = 0.015, nonlinear P = 0.086). Moreover, CDAI partially mediates the association of total flavonoid intake with femur BMD. Conclusions Our findings suggest that higher flavonoid intake is associated with higher BMD and lower risk of osteoporosis in Americans. Furthermore, we found distinct associations between different flavonoid subclasses and osteoporosis risk. More studies with stronger evidence are needed to explore the causal association between flavonoid intake and bone health and their underlying mechanisms.

Abstract Background Under Thailand’s universal health coverage every citizen has access to primary care including free hypertension treatment. This study describes temporal trends in hypertension prevalence, awareness, treatment, and control in Thailand. Methods Data were analyzed from four survey cycles of Thailand’s National Health Examination Survey (NHES), between 2004 and 2019–2020. The NHES is a nationally-representative cross-sectional survey conducted every five years using a multistage probability sample. Hypertension was defined as systolic blood pressure > = 140 or diastolic blood pressure > = 90 mmHg or currently taking antihypertensive medicines; blood pressure control was defined as

Abstract Background This study aims to validate a hypothesized model of the relationships between optimism, resilience, coping, parenting stress, perceived social support, and anxiety, as well as their influencing factors and consequences among caregivers of children diagnosed with cleft lip and/or palate (CL/P). Methods A hypothesized model was proposed based on diathesis-stress theoretical model and existing literature. A convenience sample of two CL/P treatment centers in China was collected between April 2019 and July 2020. Various well-validated instruments were used to collect 248 valid data points. Descriptive statistics and correlations were computed to assess model fitness and path analysis was performed to investigate direct and indirect effects. Results The results revealed that the average level of anxiety among caregivers of children suffering from CL/P was 3.00 (0.00,6.00). The fitness of the modified path model was evaluated using various measures, including χ2/df = 1.806, GFI = 0.989, RFI = 0.916, IFI = 0.990, CFI = 0.989, TLI = 0.960, RMSEA = 0.0570. Parenting stress had the greatest direct associated with anxiety, followed by perceived social support. Moreover, indirect relations to anxiety were observed for optimism, resilience, and coping, which were mediated through perceived social support and parenting stress. Conclusion In summary, this work suggests that both parenting stress and perceived social support in caregivers of children suffering from CL/P are associated with anxiety. Therefore, developing effective intervention approaches targeting key factors might potentially instrumental to alleviate anxiety.

Abstract Background Mental health apps (MHA) have gained popularity in recent years. Most freely available apps are of low quality and lack evidence for effectiveness. Yet, download rates indicate high usage. MHA are potentially beneficial for individuals with no/low symptom severity as prevention, or as an option to reach underserviced populations. However, currently very little is known about the characteristics of MHA users in the general population, about the kind of MHA used, or the motivation behind MHA usage. Methods We collected survey-data from N = 1,247 individuals from the general population to investigate MHA usage. Results Descriptive statistics revealed that 41% had used MHA in the past 12 months; prescription app-use however was low (1.5% of MHA users). Mindfulness, moodtracking, and relaxation were the most popular categories of MHA. Perceived helpfulness, fun, and availability were the top reasons for MHA usage. Non-users reported distrust, lack of perceived need, and data security concerns as usage barriers. MHA users and non-users did not differ regarding sociodemographic variables. Multiple regression analyses revealed that sub-threshold symptoms of psychological disorders as well as higher levels of anxiety and stress were linked to higher probability of MHA usage. Higher levels of depression were associated with lower likelihood of MHA usage in general, but increased likelihood of usage of self-help apps specifically for depression. Conclusions It follows that MHA use is common in the general population independent of sociodemographic characteristics. MHA can reach people who might benefit, but more awareness and better structure of the market is needed to reduce distrust, increase usage of high-quality MHA, and improve the fit between app and user.
