This study assessed the association between fine particulate matter (PM_2.5) exposure during pregnancy and stillbirth in Pakistan. We hypothesised that higher PM_2.5 exposure is linked to increased stillbirth risk.

A cross-sectional study using secondary data from the 2017 to 2018 Pakistan Demographic and Health Survey (PDHS), combined with satellite-derived PM_2.5 exposure data.

The study covered urban and rural areas across Pakistan, including all four provinces (Punjab, Sindh, Khyber Pakhtunkhwa and Baluchistan) and administrative regions (Gilgit-Baltistan (GB), Islamabad, Federally Administered Tribal Areas and Azad Jammu Kashmir).

The study included 9172 married women aged 15–49 with at least one birth in the past 5 years. Women with incomplete pregnancy outcome data were excluded.

PM_2.5 exposure was estimated using satellite data, matching PDHS clusters with the nearest air quality point via MATLAB. Monthly average exposure was categorised into quartiles.

Stillbirth, defined as pregnancy loss at ≥28 weeks gestation.

Multivariable logistic regression was used to assess the association between PM_2.5 and stillbirth, adjusting for maternal age, gravidity, wealth index, birth interval, previous adverse pregnancy outcome and region of residence. The stillbirth rate in Pakistan for the most recent pregnancy was 17.0 (14.5–19.9) per 1000 births, with highest rates (28.9) in Baluchistan province. The mean level of PM_2.5 exposure in Pakistan was 53.96 (SD 20.42; range 5.9–209.4) µg/m³. PM_2.5 exposure was higher for urban (56.43) than rural (51.87) pregnancies, highest in Sindh (78.06) and lowest in GB (13.41) provinces. For every 1 µg/m³ average increase in PM_2.5 during the pregnancy period, there was approximately 1% increase in stillbirth.

Increased PM_2.5 exposure was strongly associated with stillbirth risk. This underscores the need for targeted public health interventions, such as government regulations, emission controls and clean energy initiatives to protect pregnant women in high-risk areas.

The EPHOR-NIGHT cohort was established to investigate how night shift work influences biological pathways and chronic disease risk using a comprehensive working-life exposome approach, focusing on cardiometabolic, mental health, cognitive and biological ageing outcomes.

The cohort includes 937 workers aged 20–65 years (88% female), primarily from the healthcare sector (96%) in Spain, Sweden, Denmark and the Netherlands. Participants were categorised as permanent day (39%), permanent night (35%) or rotating/other shift workers (26%). Data collection included questionnaires, daily ecological momentary assessments, wearable sensors tracking light, physical activity, heart rate and environmental exposures and biological samples (blood collected once and saliva collected during five points across the day), with harmonised protocols across countries.

From the 937 participants contributing data to the cohort, 708 had complete information from questionnaires, sensors and blood and saliva, with subsets undergoing advanced biological analyses, including genomics, targeted and genome-wide DNA methylation, telomere length and mtDNA copy number, metabolomics, transcriptomics, proteomics, hormone profiling and inflammatory biomarkers and blood metals. Many reported prevalent chronic conditions, including anxiety (27%), depression (18%) and metabolic disturbances. Night shift and rotating shift workers had greater exposure to long shifts and more scheduled rest days compared with day workers. Sleep duration and quality were poorest among permanent night shift workers.

A 2-year follow-up was completed in June 2025, including the collection of additional biomarker data, psychosocial work environment data and data related to female sexual and reproductive health. Findings from the EPHOR-NIGHT study aim to inform prevention strategies and occupational health policies. Data will be made available to support broader research efforts on shift work and health.

To develop a machine learning (ML)-based predictive model to determine the key predictors of dissatisfaction after occupational injury (OI).

A retrospective cohort study.

Nationwide 5-year panel data (2018–2022) from the Panel Study of Workers’ Compensation Insurance in South Korea.

A total of 2298 workers who completed compensation-related medical care in 2017.

Predictive modelling was conducted with extreme gradient (XG) Boost, light gradient boosting machine (GBM), CatBoost and random forest. SHapley Additive Explanations (SHAPs) analysis was conducted to interpret the feature importance. Further, logistic regression was conducted for comparison.

This study evaluated postinjury satisfaction among workers using survey items associated with satisfaction levels. We adopted a 5-year follow-up period.

Of the 2298 participants, 570 were dissatisfied. The logistic regression model indicated that dissatisfaction was significantly associated with unemployment (adjusted OR (aOR) 1.701; 95% CI: 1.296 to 2.233), lack of private health insurance (aOR 1.347; 95% CI 1.042 to 1.741) and lower perceived socioeconomic status (aOR 2.097; 95% CI 1.109 to 3.965). Among the ML models, light GBM exhibited the highest area under the receiver operating characteristics curve (0.770 (95% CI 0.718 to 0.819)), followed by CatBoost (0.768 (95% CI 0.718 to 0.815)), random forest (0.766 (95% CI 0.715 to 0.814)) and XGBoost (0.765 (95% CI 0.717 to 0.811)). The SHAP analysis demonstrated the total number of household members, extent of pain interference with daily life, perceived health status before injury and financial factors as the strongest predictors.

This study developed and demonstrated robust predictive performance of an ML-based model for determining dissatisfaction after OI. The key features included employment status, financial stability, chronic pain and cognitive function, highlighting the multifaceted nature of worker satisfaction.

This study aimed to investigate the evolution of burnout levels and cardiovascular risk among healthcare professionals during the COVID-19 pandemic, identifying associated risk factors, with a particular focus on the impact of working hours, job roles and working units.

A longitudinal, observational study was conducted.

The study was carried out in a medical centre in central Taiwan, encompassing various healthcare settings.

A total of 1502 healthcare workers participated, including nurses, medical technicians, resident doctors, attending physicians and administrative staff. Participants were selected based on consistent completion of a 4-year questionnaire, with exclusion criteria for those who did not complete.

The primary outcome measured was burnout levels using the Chinese version of the Copenhagen Burnout Inventory. The secondary outcome was cardiovascular risk calculated from employees’ health check-up data using the Framingham Risk Score.

Cardiovascular risk showed an upward trend over 4 years. Personal and work-related burnout significantly decreased from 2019 to 2020 but increased from 2020 to 2022, aligning with changes in weekly working hours. Nurses exhibited the most pronounced fluctuations, likely due to their younger average age, shorter professional tenure and frequent direct patient contact, which may heighten vulnerability to pandemic-related stressors. In contrast, attending physicians demonstrated age as a protective factor against burnout, as greater seniority, clinical experience and professional maturity may buffer stress and foster resilience. Participants who worked in COVID-related units generally had elevated burnout levels and working hours. During the initial outbreak in 2020, employees working in COVID-related units had reduced working hours but stable burnout levels, while employees in non-COVID-related units experienced decreased burnout.

This study highlights the critical impact of long working hours on burnout among healthcare professionals during the COVID-19 pandemic. Nurses emerged as a vulnerable group, sensitive to pandemic-induced changes, while attending physicians exhibited more resilience. COVID-related units face greater stress and are less likely to benefit from reductions in patient numbers and working hours during the pandemic. Our findings underscore the urgent need for tailored interventions, such as regulated work hours, flexible scheduling and enhanced organisational and peer support, to protect healthcare workers’ well-being. These strategies can strengthen workforce resilience and sustainability in future public health crises.

To explore how chronic respiratory diseases (CRDs) affect lung health, mobility, frailty and activity levels among young to middle-aged male dairy workers.

This cross-sectional study was conducted from November 2023 to February 2024 across 17 dairy farms in Punjab, Pakistan, involving 380 male dairy workers aged 25–40 years.

Participants were grouped by respiratory health status (chronic respiratory conditions vs healthy workers). Assessments included spirometry (forced expiratory volume in 1 s (FEV₁), forced vital capacity (FVC), FEV₁/FVC), functional tests (6 Minute Walk Test (6MWT), Timed Up and Go (TUG)), FRAIL (Fatigue, Resistance, Ambulation, Illnesses and Loss of weight) questionnaire and International Physical Activity Questionnaire-Short Form for physical activity. Body mass index was calculated from anthropometric data. Data were analysed using t-tests, ² tests, correlations and regression; a p

Of the 380 male dairy workers enrolled, 365 were included in the final analysis (180 with respiratory conditions, 185 without respiratory conditions). Group A (workers with CRDs, including chronic obstructive pulmonary disease, chronic bronchitis and occupational asthma) demonstrated significantly poorer outcomes compared with group B. Specifically, lung function was markedly reduced in group A (FEV₁: 62.9% vs 91.5%, p=0.002). Functional performance was also impaired, as shown by shorter 6MWT distances (390.7 m vs 479.6 m, p=0.009) and slower TUG times (10.3 s vs 7.7 s, p=0.005). Frailty was almost four times more common in workers with CRDs than in those without (38.9% vs 10.8%, p=0.001). Likewise, low physical activity was substantially higher among workers with respiratory conditions (45.6% vs 10.3%), whereas high activity levels were predominantly observed in those without respiratory conditions (58.9% vs 16.1%). Regression analysis further identified FEV₁, age, frailty status and presence of a respiratory disease as significant predictors of functional capacity.

CRDs among male dairy workers are associated with impaired lung function, decreased physical performance, lower physical activity levels and higher frailty.

Being exposed to adverse psychosocial working conditions contributes to poor mental health in young workers. This study explores whether psychosocial work adversities are a necessary condition for work-related emotional exhaustion in young workers.

Data from the ‘Netherlands Working Condition Survey 2021’ was used. By applying a novel method called Necessary Condition Analysis, we tested two psychosocial work adversities as necessary conditions for high work-related emotional exhaustion in young workers: (1) a composite score of high job demands and low job resources and (2) a composite score of high job demands. Additionally, we tested whether the threshold for job demands as a necessary condition for high work-related emotional exhaustion differed for young workers with low versus high resources.

Secondary data analysis on a national working population-based survey.

The sample included 5791 young workers in the Netherlands (aged

Work-related emotional exhaustion.

A high level of the composite on job demands and job resources is necessary for a high level of work-related emotional exhaustion in young workers (effect size=0.11, p

Both psychosocial work adversities were necessary conditions for high work-related emotional exhaustion in young workers. The necessity threshold for job demands was higher for young workers with high job resources, compared with the group with low resources. This indicates that removing psychosocial work adversities and ensuring the presence of job resources might contribute to the prevention of high work-related emotional exhaustion in young workers.

It has been reported that pregnant women used more cosmetics daily than non-pregnant women. Phenoxyacetic acid is the main metabolite of phenoxyethanol, the most frequent preservative in cosmetics used in Europe, previously associated with reproductive effects (longer time to conception, endocrine disruptors in newborns and poorer verbal comprehension in children). In France, specialised platforms (PREVention ENvIronment Reproduction (PREVENIR)) in university hospital maternity wards are dedicated to evaluating environmental and occupational exposures in patients with pregnancy-related pathologies and supporting targeted prevention efforts. These platforms are composed of occupational health physicians, obstetrician-gynaecologists, midwives, occupational health nurses, and occupational health and environmental engineers. To assess the efficacy of these platforms, we developed a randomised clinical trial, the protocol for which is presented in this paper. The primary objective of the PREVENIR-G Study is to compare the change in urinary phenoxyacetic acid concentrations from baseline to 3 months postintervention between an intervention group and a control group. To date, the intervention has been integrated into routine care in certain facilities; however, its efficacy remains unproven. It is therefore essential to assess the relevance of this intervention, considering both its potential benefits and any adverse effects, such as increased stress or anxiety.

This study is an unblinded, randomised clinical superiority trial with two parallel groups (intervention vs no intervention) in four university maternity hospitals in France. We will include 300 pregnant women (aged 18 years or older) who are under 24 weeks of gestation (150 per group) referred to the participating PREVENIR platforms for management. The intervention will consist of clinical prevention management through the PREVENIR platforms, involving a consultation with an environmental health expert for an assessment of environmental and occupational exposures. During the consultation, targeted prevention messages will be provided based on identified exposures. The no intervention comparator will be a waiting-list control group. At the inclusion visit, patients will receive urine collection vials for samples to be collected at baseline and again at 3 months. Urine samples will be collected twice in a single day, on three separate days, during the collection week at home. In the week following the urine collection period, only participants in the intervention group will engage with the PREVENIR platforms. The primary outcome will be the difference in the urinary phenoxyacetic acid concentration between baseline and 3 months postintervention, compared between the intervention and control groups.

The study has been approved by the hospital ethics committee (CCP Ouest 2, no. 2023-A00941-44). All participants will provide written informed consent. Results will be shared through presentations and publications.

NCT06642818

To identify and explore variable groups and individual predictors of long sickness absences outside of well-known predictors such as service use and previous sickness absence using machine learning, explainable artificial intelligence methods and a submodel approach.

Retrospective study of prospectively collected registry data on sickness absences and a questionnaire used in health examinations.

Electronic medical record data of one large occupational health service provider in Finland.

11 533 employees of various occupations who, between 2011 and 2019, had at least once completed a health questionnaire that could be linked to service usage data and who had not had their initial health check within 1 year before or 3 months after completing the questionnaire.

To identify predictors of at least one long sickness absence period (≥30 days) during a 2-year follow-up.

The highest area under the receiver operating characteristic curve (AUROC) values among the submodel groups were for the sickness absence and service use submodels (0.68–0.74). The AUROC values for the submodels of sociodemographic factors, health habits or diseases data category ranged from 0.55 to 0.67 and from 0.55 to 0.67 for the submodels of questionnaire data. The AUROC value of the ensemble model that combined all submodels was 0.79 (95% CI 0.788 to 0.794).

The most important factors predicting long sickness absences based on the submodels were reported pain, number of symptoms and diseases, body mass index and short sleep duration. Additionally, several work and mental health-related variables increased the risk of long sickness absence.

Other variables besides service use and sickness absence increase the accuracy in predicting long sickness absence and providing information for planning interventions that could have a beneficial impact on work disability risk.

Traditional wellness programming focuses on bringing together individual clinicians during personal time for resources and skill building, without a focus on skill building in the contexts and teams they are embedded in daily. We developed a dialectical behaviour therapy (DBT)-informed consultation group, ‘Complex Care Rounds’ (CCR), implemented within the usual workflow of a primary care clinic. The goal of CCR was to facilitate interprofessional team communication and enhance clinician motivation and efficacy, while simultaneously addressing medical and social needs of patients. During the twice-weekly group, team members provided validation and shared feedback while acknowledging the needs of the clinician and patient. The aim of this study was to explore clinician perspectives on participation in CCR and to create a conceptual model to understand CCR’s influence on individual team members as well as team dynamics.

The research was completed at the Comprehensive Care Programme, a primary care programme for patients with Medicare insurance at high risk of hospitalisation at an academic institution in Chicago, Illinois, USA.

This was a qualitative research study examining reflective essays written by participants on how participating in CCR has impacted them. Template analysis, a form of thematic analysis, was applied to code and organise themes.

Participants included 12 clinical team members (physicians, nurses, social service team members) and 7 trainees (AmeriCorps members, medical students) from the Comprehensive Care Programme.

We found that CCR’s shared team frameworks (theme 1) grounded in DBT promoted a practice of self-compassion (theme 2) as well as a validating team environment (theme 3) within our interprofessional team. Improvements to patient care (theme 4) extended from increased personal capacity, support from team members and a structured approach to team interactions.

DBT-informed consultation groups embedded within a clinical practice have the potential to promote a practice and culture of interprofessional team members tending to self and others, while also building one’s own skills and capacity to care for complex patients.

Clinical trial: NCT04489693; Pre-results"

To examine (1) the mediating roles of self-efficacy and future-oriented time perspective (FTP) in the association between workplace culture of health (COH) and diabetes self-management and (2) the moderating effect of diabetes distress on the relationship between self-efficacy and FTP among employees with type 2 diabetes mellitus (T2DM).

A cross-sectional survey.

This study was conducted among employees with T2DM recruited from the Endocrinology Outpatient Departments at three tertiary hospitals in Taiyuan City, Shanxi Province, China, between March and October 2024.

The participants were 462 employees with T2DM who had been employed at their current organisations for at least 3 months following their T2DM diagnosis.

Data on demographics, diabetes-related and work-related factors, workplace COH, self-efficacy, time perspective, diabetes distress and self-management performance were collected via a survey. The moderated mediation effects were examined using Hayes’s PROCESS macro.

Workplace COH was associated with diabetes self-management both directly (β=0.251, 95% CI 0.080 to 0.422, p self-efficacy -> diabetes self-management (indirect effect=0.207, 95% CI 0.110 to 0.308); (2) workplace COH -> self-efficacy -> FTP -> diabetes self-management (indirect effect=0.093, 95% CI 0.051 to 0.144). However, the indirect pathway: workplace COH -> FTP -> diabetes self-management was not significant (indirect effect=0.004, 95% CI –0.055 to 0.063). Additionally, a significant interaction (β=–0.356, 95% CI –0.566 to –0.146, p

This study demonstrated that workplace COH was associated with diabetes self-management both directly and indirectly, specifically through self-efficacy alone and serially through self-efficacy and FTP; it also confirmed that diabetes distress weakens the effect of self-efficacy on FTP, thereby providing a basis for developing interventions to improve self-management among employees with T2DM.

To develop, evaluate and validate the musculoskeletal health climate questionnaire (MHCQ), a multidimensional questionnaire for measuring musculoskeletal health climate.

Cross-sectional test–retest study including systematic scale development and psychometric validation.

The questionnaire was developed following the best practice recommendations for scale development outlined by Boateng et al (2017), including item development, scale development and scale evaluation with input from experts, stakeholders and the target population. Validation was conducted among employees in three physically demanding occupations in Denmark (care workers, slaughterhouse workers and residential painters), where a total of 1420 participants were recruited through labour unions. Of these, 796 completed the retest survey 30 days later. Exploratory and confirmatory factor analyses (EFA and CFA, respectively), internal consistency (Cronbach’s α), test–retest reliability (intraclass correlation coefficients (ICC)) and SEM were used to assess the psychometric properties. Criterion validity was examined via associations with pain points, pain medication use and sickness absence. Construct validity was assessed using correlations with the prevent for work questionnaire (P4Wq).

EFA and CFA supported a four-factor model (supervisor’s practices, workplace practices, worker involvement practices and workers’ pain practices) with good to excellent fit (comparative fit index, 0.96–0.99; root mean square error of approximation, 0.04–0.06). All scales showed high internal consistency (α=0.80–0.88) and excellent test–retest reliability (ICC=0.86–0.92). Associations with musculoskeletal outcomes supported criterion validity. Weak to moderate correlations with the P4Wq subscales (rho

The MHCQ provides a validated, multidimensional tool to assess workplace climate related to musculoskeletal health. It can support workplace assessments and prevention efforts by capturing shared perceptions of leadership, support, involvement and pain-related norms. Further longitudinal research and the use of objective outcome data are needed to assess predictive validity and strengthen the instrument’s applicability across settings.

Globally, over 2.3 million people die each year as a result of diseases or injuries related to their jobs, and 313 million suffer from non-fatal ailments. Welding is one such profession, which is a hazard-prone job with several potential risks, including burns, electrocution and the potentially deadly risk of fume exposure. In Nepal, people taking the welding profession are aware of the risks associated with their jobs, but they often do not take preventive measures because of ignorance, perceived discomfort in their jobs and lack of knowledge about occupational safety laws and regulations. This increases the probability of accidents.

The objective of this study was to explore occupational health risks and safety awareness among welders and their adherence to occupational safety and health regulations in Nepal.

A qualitative, cross-sectional study employing a thematic analysis approach was adopted.

The research was conducted in small-scale welding workshops located in a semiurban area in Bhaktapur District, central Nepal, reflecting the informal industrial sector.

26 male welders, aged 18–42 years, originally from nine districts across Nepal, participated, each from a different workshop, thus reaching 26 small-scale welding workshops. All were engaged in welding work at the time of the study. Participants were selected using snowball sampling. Most had not completed secondary education and had work experience ranging from 1 to 22 years.

As a qualitative study, the primary outcome was the thematic exploration of welders’ experiences. The main themes included occupational health risks and injury management, personal protective equipment (PPE) use and barriers, access to healthcare and insurance, and awareness of occupational health and safety (OHS) policies and training opportunities.

The study revealed significant occupational health risks, including eye burns, electric shocks and physical exhaustion among the welders. Further, the participating welders reported limited access to health insurance and inadequate awareness and access to PPE. Furthermore, awareness of safety policies is also low among welders. While support groups and associations exist, their support is often insufficient, thus perpetuating challenges in workplace safety.

This study provides a glimpse of the ground reality of welding workers in small-scale industries in Nepal, showing gaps and the need for safe occupational practices that must be addressed. Further study and work are needed to establish better occupational safety practices and improve the health and safety status of welders.

The teaching profession plays a crucial role in society. From educating and forming future generations to fulfilling various administrative tasks and managing expectations and experiences that reach beyond the classroom—teachers face immense demands on their time, energy, and emotional resources. Consequently, they are subject to high work burden. This is reflected in the high prevalence of burnout, anxiety, and depression among teachers. A scoping review of factors associated with these outcomes in teachers is required to inform the further development of preventive occupational medicine strategies. In this scoping review, we aim to (i) identify and (ii) appraise the factors (eg, workplace, environmental, lifestyle, psychological) associated with burnout, anxiety, and depression specific to secondary school teachers and to (iii) synthesise the findings from the perspective of preventive occupational medicine.

The scoping review will be performed following the PRISMA extension for Scoping Reviews guidance. A systematic literature search will be conducted in the Medline, Web of Science Core Collection, PsychInfo, and Cochrane Library databases using search terms pertinent to secondary school teachers as the population of interest and depression, anxiety, and burnout as the outcomes of interest. Returned articles from the database search published pre-2017 will be excluded for the following reasons; namely, (a) that current literature will more closely reflect the current demands of the teachers, (b) the timing fits with recent systematic reviews highlighting burnout, anxiety, and depression as major problems among teachers, and (c) it facilitates feasibility of review in terms of the volume of studies. Remaining records will then be deduplicated and screened against predefined eligibility criteria that also add focus on teachers and these outcomes. Relevant data concerning factors associated with burnout, anxiety, and depression in teachers will be extracted and mapped. A narrative appraisal of included studies will be employed that will be specific to the validity of the results regarding factors (exposures, mediators, effect modifiers) that may affect the outcomes of interest (as opposed to more generic appraisal of the entirety of individual articles). Findings will be narratively synthesised from the perspective of preventive occupational medicine.

Formal ethical approval is not required as primary data will not be collected in this study. The findings of this study will be disseminated through peer-reviewed publication, conference presentation, and condensed summaries for key stakeholders and partners in the field (including teachers, schools, and governing bodies).

The protocol was registered on the Open Science Framework on 26.06.2025 and can be identified using the following link: https://doi.org/10.17605/OSF.IO/BKX56.

To explore existing evidence for the provision of support for return to work (RTW) in long COVID (LC) patients and the barriers and facilitators to taking up this support.

A rapid review reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The study was preregistered in PROSPERO (ID: CRD42023478126).

Searches were completed in June 2024 across major databases including MEDLINE, Embase, PsycINFO, evidence-based medicine reviews, Web of Science and Google Scholar.

Included studies focused on people with LC (PwLC) symptoms lasting over 12 weeks and addressed either: (1) non-workplace- or workplace-based support for RTW and/or (2) barriers and facilitators to RTW in this population.

A quality assessment was conducted using the JBI Systematic Reviews critical appraisal tool. The data were summarised in tabular format and a narrative synthesis.

Twenty-five studies were included. While many studies demonstrated rigorous methodologies and low risk of bias levels, some had high and medium risk levels. Non-workplace-based support was mostly measured quantitatively and included interdisciplinary healthcare programmes, clinical interventions and rehabilitation programmes focusing on pacing and breathing strategies. Compensation and insurance schemes were important funders of these interventions.

Workplace-based support was mostly measured qualitatively. Barriers to the provision of support at organisational level included lack of understanding of LC symptoms, insufficient workplace guidance and educational gaps among managers. Individual barriers included threat of income loss, remote working and disconnection from the workplace. Facilitators for support included recognition and validation of LC and its symptoms, and eligibility for disability benefits associated with work.

RTW is an important outcome of health-related absence and should be systematically recorded in studies of PwLC. The heterogeneity and unpredictability of LC symptoms create challenges for supporting working age populations. Further research is crucial to better understand the specific RTW needs for PwLC and address potential barriers and facilitators to workplace-based support, particularly through interventions, organisational practices and employ-led policies that enable sustained RTW. Consistent guidelines on LC’s definition and disability status may facilitate the provision of support and the development of interventions.

CRD42023478126.

The aim of this study was to analyse associations between crowded housing and children’s indoor living environment, respiratory and allergic disorders and general health.

A cross-sectional study.

Sweden, using data from the Swedish National Environmental Health Survey 2019.

The study sample included 48 512 children (aged 6–10 months, 4 years and 12 years). We also investigated associations in vulnerable subgroups, such as children with asthma and those living under unfavourable socioeconomic conditions.

Primary outcomes in the living environment were at least one sign of mould, poor indoor air quality, unpleasant odours, too warm indoors in summer and too cold indoors in winter. Primary outcomes for children’s health were asthma, airway problems, breathing difficulties, rhinitis symptoms, mould and mites allergy, pollen allergy, furred pet allergy and good general health.

About one in five children lived in an overcrowded home. Factors from the indoor living environment such as perceived poor indoor air quality and mould were significantly associated with crowded housing. Moreover, children who lived in overcrowded conditions were less likely to report good general health than children in non-crowded households (OR 0.64, 95% CI 0.54 to 0.76). This association was even stronger in children with asthma (OR 0.51, 95% CI 0.34 to 0.77). Few significant associations were, however, observed with the respiratory and allergic health outcomes.

Crowded housing is associated both with a poor indoor environment and with poorer general health in children. Children with asthma may experience even poorer general health.

Interest in workplace bullying (WPB) has been steadily growing with a focus on understanding its consequences as well as prevalence rates in different occupations and across different countries with varying cultural contexts. Research in the Middle East remains limited, especially in Lebanon. The scarcity of data from the Lebanese healthcare sector underscores the need to better understand WPB in this unique sociocultural and organisational environment.

The primary aim of this study is to investigate the prevalence of WPB among healthcare providers and hospital staff in Greater Beirut. The secondary aim is to investigate the relationship between WPB, psychological well-being, burnout and sick leaves in the Lebanese cultural context.

A cross-sectional study design was conducted.

Seven hospitals in Greater Beirut took part in the study, including six private hospitals and one public hospital.

A total of 958 participants aged 18–64 were recruited using stratified proportionate non-random sampling. Stratification by hospital size and department aimed to ensure broad representation of nursing and support staff across institutions. The participants included nursing and supporting staff, of which 26.3% were males and 73.7% were females. Those employed for less than 6 months were excluded.

The Arabic versions of each of the Negative Acts Questionnaire-Revised (NAQ-R), the General Health Questionnaire (GHQ-12) and the Copenhagen Burnout Inventory (CBI) were administered. These instruments were selected for their established reliability and widespread use in cross-cultural occupational health research. Surveys were administered via paper-and-pencil (six hospitals) and online (one hospital). Prevalence of bullying using the NAQ-R cut-off scores was first calculated and then their respective thresholds identified using receiver operating characteristic analysis. Pearson’s correlation coefficient was used to evaluate the relationship between the NAQ-R and the GHQ-12, CBI and number of sick leaves.

Using the lower threshold as a cut-off on the NAQ-R, 35.1% of participants were classified as bullied. When applying the higher threshold as a cut-off, the percentage was slightly lower but remained comparable at 32.4%. Results showed that across the two outcomes, those who were bullied both when using a lower threshold and upper threshold were significantly more distressed and burnt out (pt(df) = –8.43, p±1.96; Upper threshold: ² (4, N=902)=9.963, p=0.019, Standardised residual for 6–10 days=2.2>±1.96).

Findings yielded lower prevalence rates of WPB among nurses and the entire sample as compared with research carried out in the Arab region. Our study further supports the impact of culture on the perpetuation of WPB and the uniqueness of Lebanon’s culture on influencing this prevalence. Results indicated that participants who were bullied were significantly more distressed, more burnt out and reported taking up more sick leaves. These findings highlight the need to consider local workplace culture when addressing bullying and reinforce the significant psychological and occupational toll bullying takes on affected individuals. Healthcare institutions are encouraged to implement and reinforce clear antibullying policies, WPB prevention strategies and confidential reporting mechanisms. Future research should explore longitudinal patterns of bullying, obtain a more nationally representative sample and examine the effectiveness of targeted interventions to create safer, more supportive work environments.

To systematically review the evidence on the association between non-standard working time arrangements (such as night work or shift work) and the occurrence of safety incidents.

Systematic review conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and using a structured narrative approach and the Synthesis Without Meta-analysis framework to evaluate and summarise findings.

MEDLINE, Embase, PsycINFO, Web of Science and ProQuest Health and Safety Science Abstracts were searched through February 2024.

We included peer-reviewed English-language studies of paid workers (18–70 years) that examined the association between non-standard working time arrangements and safety incidents (accidents, near-accidents, safety incidents or injuries), excluding cross-sectional designs and studies on unpaid workers, athletes or military personnel.

Two reviewers independently extracted data and assessed risk of bias using standardised forms, extracting study characteristics (author, year, country, sector and population), working time arrangements and exposure assessment, outcomes and their assessment, and reported risk estimates. We conducted a narrative synthesis, classifying studies into three exposure contrasts (shift worker versus non-shift worker, time-of-day and shift intensity), and summarised risk estimates using forest plots without calculating pooled effects.

A total of 13 569 records were screened, and 24 studies met the inclusion criteria. The results indicated that shift workers generally had an elevated safety incident risk compared with non-shift workers (risk estimates ranged from 1.11 to 5.33). Most of the included studies found an increased risk of safety incidents during or after night shifts. Accumulated exposure to evening or night shifts increased the risk of safety incidents during the following 7 days. However, bias and heterogeneity across studies in design, populations and outcome measures resulted in an overall low to very low certainty of the evidence.

Non-standard working time arrangements, including night and evening shifts, appear to increase the risk of occupational safety incidents. Despite the low certainty of evidence, the findings highlight a potential area for preventive measures in work scheduling. Future longitudinal studies using individual data on daily working hours are needed.

Among the emergency services, firefighters have the highest percentage of mortality (45%) due to sudden cardiac death, with the majority related to underlying cardiovascular disease. This necessitates that firefighters stay in good physical condition and maintain adequate cardiovascular fitness to cope with these stressors and perform their duties with minimal health risks. Therefore, this study aims to determine the association between metabolic syndrome and physical fitness in firefighters.

The authors will search the following electronic databases: PubMed/Medline, SCOPUS and Web of Science, with no limitations to publication year. For data extraction, the two principal reviewers will use a general data extraction form to retrieve the key characteristics of each study. The Rayyan intelligent systematic review tool will be used to screen and select studies for inclusion. Thereafter, information from the included studies will be captured on the researcher-generated data extraction form. The Joanna Briggs Institute (JBI) Critical Appraisal Tools for quantitative studies will be used to conduct the methodological assessment of each study included. Data will be analysed using Review Manager 5.3 to determine the exposure effects and MedCalc statistical software Ltd and will be used to determine the pooled correlation effects. The results will be presented using figures, graphs and tables.

Details for this systematic review protocol can be accessed on PROSPERO (CRD42024535088). The authors will disseminate this protocol and the findings of the systematic review and meta-analysis in peer-reviewed journals and in national and international conferences. In addition, this review will add significantly to the body of knowledge in the scientific community worldwide and assist academics in exploring research gaps on this topic.

There is a wealth of reviews investigating the relations between healthcare worker (HCW) variables and quality of care (QoC) outcomes. Individually, these reviews predominantly focus on one aspect relevant to HCWs’ functioning at work, unintentionally contributing to a scattered body of evidence. This umbrella review uses the concept of sustainable employability (SE)—a multidimensional construct that captures an individual’s long-term ability to function adequately at work and in the labour market—to integrate existing reviews on the topic, and to examine if and how HCWs’ SE is related to QoC.

An umbrella review of systematic reviews was conducted.

Systematically conducted reviews or meta-analyses of empirical primary studies (quantitative, qualitative or mixed methods) were included.

Reviews were eligible for inclusion if they included studies that focused on HCWs providing direct patient care; explored a relation between SE indicators and QoC outcomes; were peer-reviewed and published in an academic journal in either English or Dutch and were appraised as high-quality reviews.

We followed the Joanna Briggs Institute manual for Evidence synthesis when conducting this review. Nine verified indicators of SE, pertaining to health, well-being and competence domains of SE, were used to identify published reviews in Embase, Medline, PsycINFO and CINAHL up until 10 May 2024. Quality of reviews was critically appraised with the Joanna Briggs Institute Critical Appraisal Instrument. Data were extracted by one reviewer in a standardised form with a second reviewer verifying outcome data that directly informed our evidence statements.

55 high-quality reviews were included, and 6 SE indicators linked to 19 QoC outcome categories were identified, distinguishing a total of 50 unique relations—whether positive, negative, partial, absent or mixed. Although extensive, evidence is disproportionally represented, with reviews on ‘burn-out’ and ‘lack of knowledge/skills’ being over-represented and well-established. Only four reviews covered multiple SE domains simultaneously.

When theoretically integrated, there is an impressive array of evidence showing the crucial role of HCWs’ SE for QoC. Researchers are advised to adopt more multidimensional perspectives and concepts to empirically validate the interrelatedness of individual HCW variables for QoC. Practitioners may use this overview to consider interventions that target multiple indicators of HCWs’ SE.

To investigate whether seafarers in Norway who were declared unfit for service at sea or received a time-limited health certificate had a higher risk of acute somatic hospital admissions compared with those who received a full health certificate.

Registry-based cohort study.

Seafarers in Norway who presented to a seafarer’s doctor to obtain a health certificate between 2018 and 2019, as required for work aboard Norwegian vessels. The study was conducted within Norway’s publicly funded healthcare system.

Norwegian seafarers aged 18–70 years who underwent medical examinations (n=43 758), including n=5452 females (12.5%).

Acute somatic hospital admission within 2 years of medical examination. HRs were estimated using Cox regression models in two separate time periods (0–3 months and 3–24 months), with adjustment for possible confounding from age, gender, level of education and centrality of residence (proximity to healthcare services).

The crude risk of acute somatic hospital admissions was higher for individuals who received a declaration of unfitness, as compared with those who received a full health certificate, in both follow-up periods: 0–3 months (HR=5.13, 95% CI: 3.27 to 8.04) and 3–24 months (HR=2.63, 95% CI: 2.07 to 3.34). Similarly, those with time-limited health certificates had a higher risk in both periods: 0–3 months (HR=2.02, 95% CI: 1.39 to 2.93) and 3–24 months (HR=2.45, 95% CI: 2.15 to 2.79). Adjustment of the analyses for socio-demographic factors did not change the effect estimates substantially.

These findings highlight the importance of comprehensive and continuous health assessments to help prevent adverse health outcomes and ensure safety at sea, particularly among vulnerable subgroups of seafarers.
