Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most prevalent chronic liver disorder worldwide and is closely linked to the components of metabolic syndrome. Shift work, through its disruption of circadian rhythms and the promotion of adverse behavioral patterns, has been proposed as a potential contributor to metabolic dysfunction and liver disease, yet evidence on its association with MASLD remains limited in large, heterogeneous occupational populations. Objectives: To investigate the association between shift work and MASLD risk using multiple validated non-invasive indices in a large sample of Spanish workers, and to explore the influence of sociodemographic characteristics, lifestyle behaviors, and sex on these associations. Methods: This cross-sectional study analyzed data from 53,053 employed adults across diverse sectors in Spain, including 31,753 men and 21,300 women. The participants underwent standardized occupational health assessments between 2019 and 2020. The MASLD risk was evaluated using seven indices: fatty liver index (FLI), hepatic steatosis index (HSI), ZJU index, fatty liver disease (FLD) index, Framingham steatosis index (FSI), lipid accumulation product (LAP), and BARD score. Sociodemographic, anthropometric, clinical, biochemical, and lifestyle data were collected. Multinomial logistic regression models were used to assess independent associations between shift work and high-risk MASLD scores. Results: Shift workers exhibited significantly higher mean values and prevalence of elevated MASLD scores across all indices compared to non-shift workers, in both sexes. In men, the prevalence of high BARD scores increased from 43.5% (non-shift) to 71.5% (shift), while in women it rose from 49.9% to 85.7%. Multivariate analysis confirmed that shift work was independently associated with an increased MASLD risk, particularly for HSI (OR: 7.83; 95% CI: 7.40–8.26) and ZJU (OR: 5.91; 95% CI: 5.60–6.22). Male sex, older age, smoking, and blue-collar status were also consistently associated with elevated risk scores. Conclusions: Shift work is significantly associated with an increased MASLD risk, independent of sociodemographic and lifestyle factors. Women and blue-collar workers may be especially vulnerable to the hepatic consequences of circadian disruption. These findings support the inclusion of liver health screening in occupational health programs and highlight the need for targeted interventions to reduce the MASLD risk among shift-working populations. Cross-sectional design limits causality; longitudinal studies are needed to confirm temporal relationships. Full article

The COVID-19 pandemic has fundamentally transformed workplace dynamics worldwide. Within this context, emerging patterns in job demand and job resources necessitate a thorough examination of how these workplace changes affect work–family interference and employee well-being across diverse occupational categories. The current study investigates the differential impact of job characteristics on job satisfaction and work stress during the COVID-19 pandemic, comparing blue-collar and white-collar occupations in China. Drawing from the Chinese General Social Survey (CGSS) database, we conducted a cross-sectional analysis using data from two time periods, 2015 and 2021, encompassing 10,968 and 8148 valid samples, respectively. Through bootstrapping analysis, we tested the indirect effects of job characteristics on employee well-being, mediated by work–family interference. The results reveal distinct patterns across occupational categories. Blue-collar workers demonstrated increased susceptibility to work-related stress, primarily due to the compounding effects of dual workload demands that intensified their work–family interference. Conversely, white-collar employees maintained a positive relationship between job autonomy and job satisfaction, despite the negative mediating influence of work–family interference. Full article

Background/Objectives: Physical trauma may cause long-term disabilities. The importance of place of residence in the return to work after injuries is little researched. The primary aims of this study were to describe return to work or school (RTW) at 6 and 12 months after moderate to severe traumatic injury and to investigate demographic and injury-related predictors for RTW with an initial focus on geographic centrality of residency. The secondary aim was to investigate the association between RTW and functioning. Methods: A prospective cohort study conducted at two Norwegian trauma centres. Inclusion criteria: age 18 to 70 years, at least a two-day hospital stay and a New Injury Severity Score > 9. Information about centrality, demographics, injuries, and return to work were collected. Associations between possible predictors and RTW were assessed using binary logistic regression. Results: Of the 223 participants, 68% had returned to work after 6 months and 77% after 12 months. Twelve-month RTW was 89% after thorax/abdomen injuries, 78% after extremity/spine injuries and 73% after head injuries. More central residency was a significant predictor for RTW in univariable but only within the extremity/spine injury subgroup in multivariable analysis. Negative factors were age, having a blue-collar job, number of injuries and rehabilitation complexity. Function 12 months post-injury was associated with RTW in the multivariable model. Conclusions: RTW after one year was high in all major trauma groups. Demographic and injury-related factors were more important predictors of RTW than centrality of residency. Blue-collar workers and patients with multiple injuries and high rehabilitation complexity should be given special attention to support RTW. Full article

Blue-collar workers in the freight transport industry report a high risk of developing chronic diseases, partly due to an unhealthy lifestyle. Worksite health promotion programs (WHPPs) may be able to promote a healthier lifestyle, but participation among blue-collar workers in these programs is generally lower than among other workers. The current study aimed to further examine factors that can explain participation of blue-collar workers in these programs. A pragmatic, qualitative study was conducted, and semi-structured interviews were held with 32 blue-collar workers in freight transport in the Netherlands (94% men, 81% driver, mean age 48 (SD = 11)). The interview guide was based on the Theoretical Domains Framework (TDF) and Capability-Opportunity-Motivation-Behavior (COM-B) model, and was used to assess perceived determinants that influence participation. A combination of framework analysis and thematic analysis was conducted, which yielded the following nine main themes: (i) not being aware of WHPPs on offer, (ii) no clear picture of what to expect, (iii) (not) giving priority to health, (iv) expecting feedback and practical support, (v) being open and ready to change, (vi) preferring to be self-dependent, (vii) being offered a practical, fun and joint WHPP, (viii) having an employer who cares, thinks along and facilitates participation, and (ix) working and living in an environment in which a healthy lifestyle is not the norm. With these insights we were able to formulate recommendations to enhance the participation of blue-collar workers in WHPPs. Full article

Background: According to the World Health Organization, an unhealthy diet and lack of physical activity constitute the primary global health risks. The purpose of this study was to as-certain the barriers to a healthy diet (HD) and physical activity (PA) as perceived by the Polish population in order to implement public health interventions. Methods: A quantitative survey was conducted using the computer-assisted telephone interview technique on a randomly selected representative sample of 2000 Polish citizens aged 18–88 years. The research tool was a questionnaire consisting of two parts: sociodemographic characteristics and examining barriers to an HD (Cronbach’s alpha = 0.899) and regular PA (Cronbach’s alpha = 0.923). Results: Women constituted more than half of the sample (53.4%), and most of the respondents lived in urban areas (60.5%), considered their financial situation as average (56.9%), and their health as satisfactory (42.3%). Barriers to an HD include the cost of healthy food (43%), lack of motivation (26.7%), and lack of time (25.4%). Barriers to taking up PA include competing priorities (29%), a lack of motivation to exercise (27.3%), feeling of constant fatigue, and lack of energy (24.4%). Limiting factors in the adoption of both an HD and PA are gender (women > men; HD p < 0.01; PA p < 0.001), financial situation (unsatisfactory; HD and PA p < 0.001), health condition (unsatisfactory; HD and PA p < 0.001), type of work (blue-collar workers; HD p < 0.001; PA p < 0.05), and employment status (people running household; HD and PA p < 0.001). Conclusions: The results of this study provide important information about barriers to adopting healthy lifestyle principles. The practical implications of our work can be used by policymakers responsible for intervention strategies and programmes to increase the number of people adhering to recommendations for an HD and PA by removing barriers.

This study aimed to identify differences in health behaviors according to the employment status and occupation of cancer survivors, as well as to identify risk factors. Using data from the Korea National and Health Nutrition Examination Survey (2008–2018), 1023 cancer survivors aged 19–60 years were classified based on their employment status and occupation, and their health behaviors were comparatively assessed. To investigate the impact of occupational status on the health behaviors of cancer survivors, we performed multivariate adjusted logistic regression analysis. Five hundred fifty-six (54.3%) cancer survivors were engaged in economic activities. After adjusting for various factors, white- and blue-collar workers exhibited an increased risk of obesity. The blue-collar group had a 1.45 times higher risk of non-practice with cancer screening, while the white-collar group had a 0.50 times lower risk of non-practice with health screening. The results provide evidence of the need to support cancer survivors in practicing healthy behaviors according to their employment status and occupation. As cancer survivors’ economic activities increase, it is necessary to help them manage their health by predicting any possible health-behavior failures. Full article

While the study of workplace bullying has been ongoing for 30 years, there remains a lack of research focused on small business workers, despite their vulnerability to workplace bullying due to personal, environmental, and social factors. Therefore, this study applied a phenomenological qualitative research method to identify the phenomenon of workplace bullying, which negatively influences the sustainable development of small-sized workplaces. Methods: This research employed Colaizzi’s phenomenological research approach to explore the meaning and core structure of workplace bullying experiences among individuals working in small businesses. The research included a sample of 10 participants, and data collection took place from May to July in 2023. This involved conducting individual interviews with each participant, varying in frequency from one to three times, and each lasting between one to three hours. Results: This study revealed several significant themes, including individuals feeling stigmatized as incompetent, experiencing gaslighting, having nowhere to run for escape, and often confronting dilemma situations. Moreover, these themes coalesced into two theme clusters: the sense of one’s identity being gradually eroded and a prevailing feeling of having nowhere to turn for help. Ultimately, the core theme that emerged from this research—“the dimly lit maze of life”—encapsulated the complex nature of these experiences. Conclusions: Eliminating workplace bullying for the long-term success and sustainable development of small-sized workplaces will require a united front, involving employers, employees, policymakers, and society at large. Therefore, as a methodology for practically addressing the problem of workplace bullying in small businesses, I propose a problem-solving-oriented participatory action research method based on an ecological model in which participants make a plan, implement the plan, observe the process, and reflect on the outcome of the implemented plan.

Virtual Reality (VR) construction safety training modules have reached a level of maturity which renders them as a serious alternative to traditional safety training modules. The purpose of this study is to investigate the usability of a particular safety training module related to “Working at heights” for blue-collar construction workers in Kuwait. A mixed study approach was applied based on a semi-quasi experimental research design, utilizing a control group/experimental group with pre-/post-test measurements, supplemented by observations. The findings indicate a statistically insignificant higher learning effectiveness of the workers exposed to the VR approach. Observations confirmed that trainees require an extended time of preparation to become familiar with moving within the virtual environment and using the related hardware. Furthermore, younger users with less work experience reported a higher usability than older users with more work experience. VR content developers are encouraged to investigate the possibilities of simplifying the virtual environment to make it more relevant for blue-collar workers, reduce the complexity of the hardware, and intensify the feeling of the consequences resulting from users’ choices. Construction companies and educational institutions training construction blue-collar workers can benefit from the VR approach to safety training if they allow sufficient time for familiarization with the virtual training module.

Heart rate variability (HRV) has the potential to be a predicting factor of cognitive performance. The present research aimed to explore the differences in neurocognitive performance of workers with high HRV and low HRV. A total of 48 white-collar workers and 53 blue-collar workers were assessed. An electrocardiogram was used to obtain HRV data, whereby a 10 min baseline and an active (neuropsychological task) recording were taken. Median splits were performed on data to obtain high- and low-HRV groups. The Cambridge Neuropsychological Test Automated Battery, specifically, the spatial working memory, attention-switching task, rapid visual processing, and spatial span were used. Higher HRV (RMSSD and HF) was linked to better neurocognitive performance measures. Interestingly, the blue- and white-collar groups exhibited different correlations and, in some cases, showed an inverse relationship with the same variables. The differences observed in the present study demonstrate the importance of assessing task-dependent HRV parameters. Full article

Introduction, objectives: Although cardiovascular events have been traditionally associated mainly with men, some data reflect an increase in women, which may even exceed their male counterparts, constituting the leading cause of death in working women in Spain. The objective of this present study was to analyze the level of cardiovascular risk in Spanish working women by assessing the influence of age, type of work, and tobacco consumption. Material, methods: A descriptive cross-sectional study was carried out in 172,282 working women from different Spanish geographical areas and from different companies between January 2018 and June 2020. A range of variables and risk factors were assessed and various cardiovascular risk scales were used to analyze the data. Results: An increase in cardiovascular risk was observed in the least qualified work groups, mainly corresponding to blue-collar workers, when using the SCORE or REGICOR risk equation. The prevalence of altered values for all the parameters analyzed (overweight and obesity, hypertension, dyslipidemia, diabetes, fatty liver, hepatic fibrosis, atherogenic indexes, and cardiovascular risk scales) was higher among blue-collar women. Age was the only factor that influenced all the cardiovascular risk scales studied, increasing risk when comparing the group of women aged 50 years and older with the others. Conclusions: Aging and belonging to the blue-collar job category meant worse results in the cardiovascular risk scales and in all the parameters analyzed. This is in line with numerous studies that argue that age and zip code are more influential than genetic code. Full article

The labour market is complex to systematise into a well-behaved structure. Here, we attempt to understand the synergy between actors and institutions in the Indian labour market and to reveal the implications for the future of work and sustainability. Combining aggregated and micro-level data from multiple sources, we examine the indicators regarding the macro economy, production and engagement in firms, and changes in the occupational structure of workers. While the familiar narrative of technology–labour acrimony emerges, it is weak. In contrast, the tie between economy and technology is a favourable representation of the proximity between human capital and technology. Inadequate human capital implies chances of non-absorption in employment, especially in the future, even for a labour-abundant country such as India. While labour market flexibility through tripartite contact work does not directly relate to labour productivity, high-wage blue-collar work is a more promising factor that aligns with productivity. On the sustainability front, upgrading environmental standards results in more cohesion between labour and capital. The conventional logic of substitutability between capital and labour is invalid when firms adopt environmental standards. From a policy vantage, the scenarios of sustainability transition to cleaner technologies and decent work require complementarity between capital and labour. Considering the dimension of upgrading in order to transition towards sustainability is an essential factor for understanding the future of work. Full article

The negative effects of long working hours and shift work on the physical and mental health of blue-collar groups should not be underestimated. Under intense stress, they have limited time to access recreational green space, and their own health is thus affected. In this study, a conceptual model of recreational satisfaction among blue-collar workers was established based on the American Customer Satisfaction Index (ACSI). The model explores the factors affecting their level of satisfaction when using recreational spaces. Anning Industrial Park in Yunnan Province was used as an example. User data were collected and analyzed using a questionnaire survey and structural equation methods. The results indicate that recreation intention, perceived park quality characteristics, and perceived value all had significant and positive effects on the park recreation satisfaction of blue-collar workers. This study applied social economics theory to the field of landscape planning, identified the typical characteristics of blue-collar workers and their green space use, and strived to optimize the UGS configuration and functional facilities through the evaluation of recreation satisfaction indexes, which provided guidance and reference for improving the service quality of green spaces.

Thread carpal tunnel release (TCTR) has been reported to be safe and effective for the treatment of carpal tunnel syndrome. The aim of this study is to evaluate the modified TCTR for safety, efficacy, and postoperative recovery. Seventy-six extremities in 67 patients undergoing TCTR were analyzed pre- and postoperatively using clinical parameters and patient-reported outcome measures. Twenty-nine men and 38 women with a mean age of 59.9 ± 18.9 years underwent TCTR. The mean postoperative time to resume activities of daily living was 5.5 ± 5.5 days, analgesia was completed after 3.7 ± 4.6 days, and return to work was achieved after a mean of 32.6 ± 15.6 days for blue-collar workers and 4.6 ± 4.3 days for white-collar workers. The Boston Carpal Tunnel Questionnaire (BCTQ) and Disability of Arm, Shoulder, and Hand (DASH) scores were comparable with previous studies. Overall, two persistent compressions and one recurrence required open reoperation (3.9%). All three had been operated in the initial phase, and none required reoperation after an additional safety step was introduced. No other complications occurred. TCTR surgery appears to be a safe and reliable technique with almost no wound and scarring and a potentially faster recovery time than open techniques. Although our technical modifications may reduce the risk of incomplete release, TCTR requires both ultrasound and surgical skills and has a considerable learning curve. Full article

The 21st century has brought a growing and significant focus on performance and health within the workforce, with the aim of improving the health and performance of the blue- and white-collar workforce. The present research investigated heart rate variability (HRV) and psychological performance between blue and white-collar workers to determine if differences were evident. A total of 101 workers (n = 48 white-collar, n = 53 blue-collar, aged 19–61 years) underwent a three lead electrocardiogram to obtain HRV data during baseline (10 min) and active (working memory and attention) phases. The Cambridge Neuropsychological Test Automated Battery, specifically the spatial working memory, attention switching task, rapid visual processing and the spatial span, were used. Differences in neurocognitive performance measures indicated that white-collar workers were better able to detect sequences and make less errors than blue-collar workers. The heart rate variability differences showed that white-collar workers exhibit lower levels of cardiac vagal control during these neuropsychological tasks. These initial findings provide some novel insights into the relationship between occupation and psychophysiological processes and further highlight the interactions between cardiac autonomic variables and neurocognitive performance in blue and white-collar workers.

Although previous studies have examined the impact of long working hours on mental health in China, they have not addressed the initial value and reverse causality issues. To bridge this gap in the literature, I conducted a dynamic longitudinal analysis to investigate the association between long working hours and the risk of mental illness nationwide. Using three-wave longitudinal data from the China Family Panel Studies conducted in 2014, 2016, and 2018, I adopted dynamic regression models with lagged long working hours variables to examine their association with the risk of mental illness. The results indicate that long working hours have positive and significant (p < 0.01 or p < 0.05) associations with the risk of mental illness (OR: 1.12~1.22). The effect is more significant for women, white-collar workers, and employees in micro-firms, compared with their counterparts (i.e., men, pink- and blue-collar workers, employees of large firms, and self-employed individuals). The results provide empirical evidence of the effects of long working hours on mental health in China, confirming the need to enforce the regulations regarding standard working hours and monitor regulatory compliance by companies, as these factors are expected to improve mental health.
