Interaction of occupational and personal risk factors in workforce health and safety

Workplace health promotion interventions in EU-27 public administrations

PURPOSE

The objective of this article is to make an exploratory study about European public administrations (public administration, public agencies, public law entities, entities dependent on the public administration and public universities) in relation to workplace health promotion interventions. The sample was extracted from the ESENER-3 (Third European Survey of Enterprises on New and Emerging Risks) (EU-OSHA, 2019) and consists of 7,981 public entities from the EU-27 countries. Four WHPI have been studied: healthy nutrition interventions, sports activities after working hours, back exercises at work and prevention of addictions.

DESIGN/METHODOLOGY/APPROACH

This is an exploratory study. The sample was extracted from the ESENER-3 (Third European Survey of Enterprises on New and Emerging Risks) (EU-OSHA, 2019) and consists of 7,981 public entities from the EU-27 Public Administration. In total, 45,420 establishments were interviewed.

FINDINGS

Different patterns have been observed when implementing workplace health promotion interventions in the EU-27 public administration. The promotion of sports activities outside working hours is the one with the highest level of implementation in European public administration. On the other hand, the measure with the least implementation level is the promotion of healthy nutrition.

RESEARCH LIMITATIONS/IMPLICATIONS

The limitations of the study are that the studied items are nominal and comprise more than two categories, so it has not been possible to develop a correlation analysis.

PRACTICAL IMPLICATIONS

The EU-27 public administrations can see which workplace health promotion interventions need to be improved.

ORIGINALITY/VALUE

Differences that may exist in the adopted workplace health promotion interventions by European public administrations have not yet been addressed in depth by the literature.

Impact of Occupational Cement Dust Exposure on Hematological Health Parameters: A Cross-Sectional Study

Introduction Contact with the dust of cement consisting of toxic components brings about inflammatory damage (often irreversible) to the body of a human being. The circulatory system exhibits sensitivity to inflammatory changes in the body, and one of the earliest changes may be observed in the blood parameters like mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC). MCHC and MCH are possibly easily accessible and affordable parameters that can detect harmful changes in the body before any irreversible damage occurs. Objectives This research aimed to seek the changes in MCHC and MCH upon occupational contact with the toxic dust of cement. Methods The execution of this research was done in the Department of Physiology, Dhaka Medical College, Bangladesh, and a cement plant in Munshiganj, Bangladesh. This research was carried out between September 2017 and August 2018. Individuals (20 to 50 years old, 92 male adults) participated and were grouped into the group with occupational cement dust impact (46 subjects) and the group without occupational dust of cement impact (46 subjects). Data was collected in a pre-designed questionnaire. An independent sample t-test was conducted to analyze statistical and demographic data like body mass index and blood pressure. A multivariate regression model was applied to note the impact of cement dust on the group working in this dusty environment. Again, a multivariate regression model was employed to observe whether the duration of exposure to this dust affected MCHC and MCH. The significance level was demarcated at p < 0.05 Stata-15 (StataCorp LLC, College Station, TX, US) for statistical analysis, and GraphPad Prism v8.3.2 (Insight Venture Management, LLC, New York, NY, US) was employed to present the data graphically when required. Results There was a reduction in MCHC by 0.58 g/dL and MCH levels by 0.68 pg in the cement dust-exposed subjects when compared to controls, but not significant (95% CI: -0.93, 2.10; p  = 0.448 and 95% CI: -0.37, 1.73; p = 0.203, respectively). However, MCHC was reduced significantly by 0.51 g/dL (p = 0.011) with the duration of exposure to the dust. Conclusion The study showed that MCHC was significantly reduced with the duration of exposure to cement dust in cement plant workers. Such alterations may hamper heme synthesis, hemolysis, and inflammatory changes in the body.

Occupational Disease in New York State: The Political Economic Context

In 1987 Landrigan and Markowitz co-authored a report entitled "Occupational Disease in New York State." They found that death and illness from occupational disease were common and that the costs of exposure to hazardous conditions warranted public funding for new occupational health infrastructure in New York State. A recent confirmatory report recognized a wider spectrum of contemporary hazards and emphasized how public health problems connect to work. These reports provide factual snapshots at 2 points in time, but they do not explain nor analyze the changing conditions they describe. Including macro-contexts such as globalization, financialization, and neoliberalism, this article demonstrates several unique occupational safety and health implications by clarifying key themes related to the state's role, especially regulation and healthcare delivery systems. Conclusions directly tie the trajectory of occupational disease to workers' collective ability to confront and roll back neoliberalism while pushing occupational disease out of its medical/science silo.

Safety and Injury of US-Certified Organic Crop Producers in the Southwest Region

OBJECTIVES

Literature on occupational risks among organic farmers is scarce. This study explored safety practices and non-fatal injuries among organic producers, and the role of sociodemographic, work, and farm characteristics on safety and injury.

METHODS

Cross sectional survey of certified organic crop producers in the Southwest (SW) region of the United States (US). The Organic Integrity Database was used for recruitment. Data were collected through an electronic and paper survey.

RESULTS

Analyses were conducted on 115 cases; response rate was estimated at 25%. A high majority of respondents owned their operation and were younger than 65 years, male, educated beyond high-school, and non-Hispanic whites. Less than half had more than 10 years of experience in organic farming; one-third worked off the farm year-round. Safety practices were very basic despite the widespread use of equipment and machinery, and limited to wearing normal clothing and apparel such hats and glasses. About half of respondents (52.6%) reported non-fatal injuries in the past year; and one-third (32.7%) time lost due to injuries. The overall cumulative incidence rate was estimated at 5.3 injuries per 10 workers within the last year. The injury rate decreased with hours worked. Significant differences were found on gender and education level and safety practices, with female respondents and the more educated being more proactive in practicing safety. Those working less than 40 h/week, in farms smaller than 50 acres, using light machinery or compact utility tractors, and tractors without roll-over protection reported significantly higher injury frequency compared to their counterparts.

CONCLUSION

This study contributes unique data on an essential workforce not captured by current occupational injury and illness surveillance systems. It identifies important personal and contextual factors that may contribute to safety and injury in this population. The findings indicate the need to promote safety and prevent injuries that result in work time lost. This study may also inform future occupational safety and health research and practice, including surveillance, injury prevention programs that target certain workers and production practices, and policies that support and protect the organic farmer.

Understanding the pathway between work and health outcomes for women during the preconception, pregnancy, and postpartum periods through the framing of maternal obesity

The link between work and health outcomes for preconception, pregnant, and postpartum (PPP) working women is complex. Further, innovation and enhanced understanding are required to address the work-related determinants of maternal obesity. However, workplace health promotion is not typically systems-based nor attuned to the specific needs and context of individual PPP women. We propose that to improve health outcomes for PPP women, we must understand the pathways between paid work and health for the individual woman by taking a systems-thinking approach. In this paper, we (a) outline the rationale for why the oversimplification or "dilution" of individual context may occur; (b) present a systems-informed pathway model (the "Context-Exposure-Response" Model) and overview of potential work-related impacts on health and wellbeing outcomes for PPP women using maternal obesity to provide context examples; (c) further investigate the role of motivational factors from a systems perspective; and (d) briefly examine the implications for policy, practice, and intervention design. It is anticipated that this research may act as a starting point to assist program developers, researchers, and policymakers to adopt a systems-focused perspective while contributing to the health improvement and obesity prevention of PPP women.

COVID-19 medical waste transportation risk evaluation integrating type-2 fuzzy total interpretive structural modeling and Bayesian network

With the amount of medical waste rapidly increasing since the corona virus disease 2019 (COVID-19) pandemic, medical waste treatment risk evaluation has become an important task. The transportation of medical waste is an essential process of medical waste treatment. This paper aims to develop an integrated model to evaluate COVID-19 medical waste transportation risk by integrating an extended type-2 fuzzy total interpretive structural model (TISM) with a Bayesian network (BN). First, an interval type-2 fuzzy based transportation risk rating scale is introduced to help experts express uncertain evaluation information, in which a new double alpha-cut method is developed for the defuzzification of the interval type-2 fuzzy numbers (IT2FNs). Second, TISM is combined with IT2FNs to construct a hierarchical structural model of COVID-19 medical waste transportation risk factors under a high uncertain environment; a new bidirectional extraction method is proposed to describe the hierarchy of risk factors more reasonably and accurately. Third, the BN is integrated with IT2FNs to make a comprehensive medical waste transportation risk evaluation, including identifying the sensitive factors and diagnosing the event's causation. Then, a case study of COVID-19 medical waste transportation is displayed to demonstrate the effectiveness of the proposed model. Further, a comparison of the proposed model with the traditional TISM and BN model is conducted to stress the advantages of the proposed model.

Expanding the Focus of Occupational Safety and Health: Lessons from a Series of Linked Scientific Meetings

There is widespread recognition that the world of work is changing, and agreement is growing that the occupational safety and health (OSH) field must change to contribute to the protection of workers now and in the future. Discourse on the evolution of OSH has been active for many decades, but formalized support of an expanded focus for OSH has greatly increased over the past 20 years. Development of approaches such as the National Institute for Occupational Safety and Health (NIOSH)'s Total Worker Health® concept and the World Health Organization (WHO)'s Healthy Workplace Framework are concrete examples of how OSH can incorporate a new focus with a wider view. In 2019, NIOSH initiated a multi-year effort to explore an expanded focus for OSH. This paper is a report on the outputs of a three-year cooperative agreement between NIOSH and The University of Texas School of Public Health, which led to subject matter expert workshops in 2020 and an international conference of global interest groups in 2021. This article traces the background of these meetings and identifies and assesses the lessons learned. It also reviews ten thematic topics that emerged from the meetings: worker health inequalities; training new OSH professionals; future OSH research and practice; tools to measure well-being of workers; psychosocial hazards and adverse mental health effects; skilling, upskilling and improving job quality; socioeconomic influences; climate change; COVID-19 pandemic influences; and strategic foresight. Cross-cutting these themes is the need for systems and transdisciplinary thinking and operationalization of the concept of well-being to prepare the OSH field for the work of the future.

Pilot study and cumulative risk framework to advance long-haul driver health

Commercial drivers are essential to the economic recovery, yet their work exposes them to many health and safety hazards. Research to improve driver health should be designed with an understanding of both the complex occupational environment and the risk management context. We present results from a small pilot study of driver health concerns and behaviors to illustrate concepts and frameworks from human health risk assessment and management that may assist in the design and translation of driver and other worker health research. The pilot study surveyed 18 long-haul truck drivers at a truck stop using an instrument adapted from the International Physical Activity Questionnaire and a transient community needs assessment developed for the US Antarctic Program Recreation and Wellness Survey. Respondents' characteristics and health concerns reflect existing literature: mostly male of older age with musculoskeletal and chronic health conditions. The two most common barriers to physical activity were lack of time and physical limitations. Applying cumulative risk assessment and risk-based decision-making frameworks, we suggest that preventive health management opportunities can be improved for these transient workers through actions of employers, truck stop owners and their communities. Considering lessons learned in implementing the pilot, cumulative risk assessment, and risk-based decision making in research design can facilitate holistic research considering co-exposures, risk factors and mitigators across multiple domains of health to inform worker protection.

Time to Return to Work After an Occupational Injury and Its Prognostic factors Among Employees of Large-Scale Metal Manufacturing Facilities in Ethiopia: A Retrospective Cohort

BACKGROUND

Globally, occupational risk factors are thought to be responsible for at least 1.9 million deaths and 90 million disability-adjusted life years per year. Occupational injury survivorship has increased in Ethiopia in recent years. However, the vast majority of the victims are young people who are impacted in their everyday life as a result of occupational injuries. While research in developed countries has revealed several factors related to early return to work, there have been very few studies of significance in underdeveloped countries, including Ethiopia.

METHODS

Metalworkers who had an occupational accident between January 1, 2017, and December 31, 2021, were investigated in a facility-based retrospective cohort. Data was collected from 422 medical records and registration books using a standardized abstraction tool. STATA 15 was used to analyze the data. The median time it took to return to work was computed. The Kaplan Meier survival curve was used to estimate the time to return to work across covariates. A multivariable Cox proportional hazard model was used to identify statistically significant predictors of return to work.

RESULTS

After a median of 45 days away from work, 310 of the 422 (73.5%) cases returned to work (95% CI 39.7-50.2). The total incidence density of return to work was 1.21 (95% CI = 1.01-1.30) per 100 person-days observed. Professional certification (AHR: 2.15, 95% CI: 1.62-2.87), working as a rigger (AHR: 1.59, 95% CI 1.20-2.10), having dependents at home (AHR = 1.59, 95% CI = 1.09-2.64), and injuries caused by body movement without any physical stress (AHR = 2.61, 95% CI = 1.92-3.56) were all associated with return to work.

CONCLUSION

Return to work is influenced by a range of factors other than the type or severity of the injury incurred. Multidisciplinary approaches such as clinical treatment and rehabilitation, ergonomics interventions, and economic and social assistance should be prioritized in the efforts to aid employees' return to work.

Latin American Agricultural Workers' Job Demands and Resources and the Association With Health Behaviors at Work and Overall Health

In the present study, we describe the job demands and job resources (JD-R) experienced by agricultural workers in three Latin American countries and their relationship to proactive health behaviors at work and overall health. Following previous research on the JD-R model, we hypothesized that job demands (H1) would be negatively related to agricultural workers' self-reported overall health. On the other hand, we hypothesized that job resources (H2) would be positively related to agricultural workers' overall health. Furthermore, we hypothesized (H3) that workers' engagement in jobsite health promotion practices via their proactive health behaviors at work would partially mediate the relationship between workers' job resources and job demands and overall health. We also had a research question (R1) about whether there were differences by type of job held. The sample of workers who participated in this study (N = 1,861) worked in Mexico, Guatemala, and Nicaragua for one large agribusiness that produces sugar cane. They worked in two distinct areas: company administration and agricultural operations. We administered employee health and safety culture surveys using survey methods tailored to meet the needs of both types of workers. Stratified path analysis models were used to test study hypotheses. In general, we found support for hypotheses 1 and 2. For example, operations workers reported more physically demanding jobs and administrative workers reported more work-related stress. Regardless, the existence of high job demands was associated with poorer overall health amongst both types of workers. We found that workers in more health-supportive work environments perform more proactive health behaviors at work, regardless of their role within the organization. However, hypothesis 3 was not supported as proactive health behaviors at work was not associated with overall health. We discuss future research needs in terms of evaluating these hypotheses amongst workers employed by small- and medium-sized agribusinesses as well as those in the informal economy in Latin America. We also discuss important implications for agribusinesses seeking to develop health promotion programs that meet the needs of all workers.

Physical work conditions and disparities in later life functioning: Potential pathways

Research in the US on the social determinants of reduced physical functioning at older ages has typically not considered physical work conditions as contributors to disparities. We briefly describe a model of occupational stratification and segregation, review and synthesize the occupational health literature, and outline the physiological pathways through which physical work exposures may be tied to long-term declines in physical functioning. The literature suggests that posture, force, vibration, and repetition are the primary occupational risk factors implicated in the development of musculoskeletal disorders, through either acute injuries or longer-term wear and tear. Personal risk factors and environmental and structural work characteristics can modify this association. In the long-term, these musculoskeletal disorders can become chronic and ultimately lead to functional limitations and disabilities that interfere with one's quality of life and ability to remain independent. We then use data on occupational characteristics from the Occupational Information Network (O*NET) linked to the 2019 American Community Survey (ACS) to examine disparities among sociodemographic groups in exposure to these risk factors. Occupations with high levels of these physical demands are not limited to those traditionally thought of as manual or blue-collar jobs and include many positions in the service sector. We document a steep education gradient with less educated workers experiencing far greater physical demands at work than more educated workers. There are pronounced racial and ethnic differences in these exposures with Hispanic, Black, and Native American workers experiencing higher risks than White and Asian workers. Occupations with high exposures to these physical risk factors provide lower compensation and are less likely to provide employer-sponsored health insurance, making it more difficult for workers to address injuries or conditions that arise from their jobs. In sum, we argue that physical work exposures are likely an important pathway through which disparities in physical functioning arise.

Ethics and Total Worker Health®: Constructs for Ethical Decision-Making and Competencies for Professional Practice

Work has become increasingly technologically driven and fast paced, with long work hours, new/emerging hazards, and rising health care costs. Threats to worker safety, health, and well-being including non-traditional work arrangements and practices, precarious work, uncertain hazardous exposures, and work organization issues, such as heavy workloads, design of work, uneven work hours, and difficult interpersonal relationships among workers and managers are apparent. Furthermore, the relationship between personal health risk factors and workplace risks and exposures has drawn increased attention and concern. As employer economic pressures continue to build, it is anticipated that ethical dilemmas for practitioners will become increasingly complex. A review of relevant Total Worker Health® (TWH) literature, related ethical constructs and competencies, an examination of codes of ethics for occupational safety and health and health promotion/education disciplines was conducted. A case study for TWH utilizing an ethical decision-making model for the analysis of key ethical issues and solutions was completed. TWH approaches to protecting safety, promoting health, and advancing well-being are increasingly being adopted. These approaches can reveal ethical dilemmas, and ethical constructs are needed to guide decision-making. A core set of proposed ethical competencies for TWH professionals are identified as a transdisciplinary framework to support workplace ethical culture.

The multi-level heat education and awareness tools [HEAT] intervention study for farmworkers: Rationale and methods

Background

The burden of adverse health effects from heat exposure is substantial, and outdoor workers who perform heavy physical work are at high risk. Though heat prevention interventions have been developed, studies have not yet systematically evaluated the effectiveness of approaches that address risk factors at multiple levels.

Objective

We sought to test the effectiveness of a multi-level heat prevention approach (heat education and awareness tools [HEAT]), which includes participatory training for outdoor agricultural workers that addresses individual and community factors and a heat awareness mobile application for agricultural supervisors that supports decisions about workplace heat prevention, in the Northwest United States.

Design

We designed the HEAT study as a parallel, comparison, randomized group intervention study that recruited workers and supervisors from agricultural workplaces. In intervention arm crews, workers received HEAT training, and supervisors received the HEAT awareness application. In comparison arm crews, workers were offered non-HEAT training. Primary outcomes were worker physiological heat strain and heat-related illness (HRI) symptoms. In both worker groups, we assessed HRI symptoms approximately weekly, and heat strain physiological monitoring was conducted at worksites approximately monthly, from June through August.

Discussion

To our knowledge, this is the first study to evaluate the effectiveness of a multi-level heat prevention intervention on physiological heat strain and HRI symptoms for outdoor agricultural workers.

Cumulative Risks from Stressor Exposures and Personal Risk Factors in the Workplace: Examples from a Scoping Review

Protecting worker and public health involves an understanding of multiple determinants, including exposures to biological, chemical, or physical agents or stressors in combination with other determinants including type of employment, health status, and individual behaviors. This has been illustrated during the COVID-19 pandemic by increased exposure and health risks for essential workers and those with pre-existing conditions, and mask-wearing behavior. Health risk assessment practices for environmental and occupational health typically do not incorporate multiple stressors in combination with personal risk factors. While conceptual developments in cumulative risk assessment to inform a more holistic approach to these real-life conditions have progressed, gaps remain, and practical methods and applications are rare. This scoping review characterizes existing evidence of combined stressor exposures and personal factors and risk to foster methods for occupational cumulative risk assessment. The review found examples from many workplaces, such as manufacturing, offices, and health care; exposures to chemical, physical, and psychosocial stressors combined with modifiable and unmodifiable determinants of health; and outcomes including respiratory function and disease, cancers, cardio-metabolic diseases, and hearing loss, as well as increased fertility, menstrual dysfunction and worsened mental health. To protect workers, workplace exposures and modifiable and unmodifiable characteristics should be considered in risk assessment and management. Data on combination exposures can improve assessments and risk estimates and inform protective exposure limits and management strategies.

How Will the Future of Work Shape OSH Research and Practice? A Workshop Summary

Growth of the information economy and globalization of labor markets will be marked by exponential growth in emerging technologies that will cause considerable disruption of the social and economic sectors that drive the global job market. These disruptions will alter the way we work, where we work, and will be further affected by the changing demographic characteristics and level of training of the available workforce. These changes will likely result in scenarios where existing workplace hazards are exacerbated and new hazards with unknown health effects are created. The pace of these changes heralds an urgent need for a proactive approach to understand the potential effects new and emerging workplace hazards will have on worker health, safety, and well-being. As employers increasingly rely on non-standard work arrangements, research is needed to better understand the work organization and employment models that best support decent work and improved worker health, safety, and well-being. This need has been made more acute by the SARS-CoV-2 global pandemic that has resulted in dramatic changes in employment patterns, millions of lost jobs, an erosion of many economic sectors, and widespread disparities which further challenge occupational safety and health (OSH) systems to ensure a healthy and productive workplace. To help identify new research approaches to address OSH challenges in the future, a virtual workshop was organized in June 2020 with leading experts in the fields of OSH, well-being, research methods, mental health, economics, and life-course analysis. A paradigm shift will be needed for OSH research in the future of work that embraces key stakeholders and thinks differently about research that will improve lives of workers and enhance enterprise success. A more transdisciplinary approach to research will be needed that integrates the skills of traditional and non-traditional OSH research disciplines, as well as broader research methods that support the transdisciplinary character of an expanded OSH paradigm. This article provides a summary of the presentations, discussion, and recommendations that will inform the agenda of the Expanded Focus for Occupational Safety and Health (Ex4OSH) International Conference, planned for December 2021.

Risk of cardiovascular disease is driven by different combinations of environmental, medical and behavioral factors: Building a conceptual model for cumulative risk assessment

The U.S. Environmental Protection Agency (EPA) and National Institute of Environmental Health (NIEHS) held a workshop in 2012 to discuss principles and applications of cumulative risk assessment (CRA). The workshop organizers chose cardiovascular disease (CVD) as an example health outcome for which cumulative risk considerations could illuminate environmental and health management strategies. To guide discussions, we developed a series of conceptual models illustrating factors influencing CVD. The CVD conceptual model represents complex processes across varying space and time scales, different causal pathways, and multiple chemical and non-chemical stressors and factors. It includes causal influences of environmental exposures and lifestyle choices, in the context of genetics and medical factors. The representation of cumulative risk as a network of interrelated nodes and arrows helps define and organize the problem and available information, determine the scope and scale, and creates a platform for analysis. It provides an interface for discussing how different entities (e.g., environmental versus health-driven organizations) can work together on different parts of the problem, and facilitates relative risk ranking and management triage. Color coding is used to distinguish categories of stressors and possible oversight responsibility. This work informs guidelines for CRA planning and assessment of factor combinations affecting real-world risk.

Working Time Characteristics and Mental Health among Corrections and Transportation Workers

OBJECTIVES

Mental health disorders are a leading cause of work disability and while the psychosocial workplace environment plays a critical role, working time characteristics are also implicated. We sought to examine the association between working time characteristics and mental health in a cohort of two unionized, full-time worker populations, correctional supervisors, and transportation maintainers.

METHODS

Using a cross-sectional study design, we surveyed workers on working time characteristics across seven domains including length of the shift, the intensity or proximity of sequential shifts, the time of day, and social aspects of work hours including predictability, variability, control, and free time. Burnout symptoms (Oldenburg Burnout Inventory) and depressive symptoms (eight-item Centers for Epidemiologic Studies Depression Scale) were assessed along with the psychosocial work environment and health behaviors. We used log-binomial regression models to estimate prevalence ratios and 95% confidence intervals after adjusting for age, gender, and company.

RESULTS

A total of 318 workers were surveyed. The majority (72%) of workers reported a fixed shift. The prevalence of burnout symptoms was higher among workers reporting more frequent shift intensity (working 6 or more days in a row) (PR: 1.15, 95% CI: 1.01, 1.31; P = 0.04). Low psychological demands and high worker social support were associated with fewer burnout symptoms, independent of working time characteristics. The prevalence of depressive symptoms was higher in workers reporting more frequent unpredictable work (PR: 1.17, 95% CI: 1.01, 1.35; P = 0.04) and was lower among workers reporting increased schedule control (PR: 0.86, 95% CI: 0.77, 0.96; P = 0.01). Higher worker social support as well as sufficient sleep and adequate exercise were associated with fewer depressive symptoms, independent of working time characteristics.

CONCLUSIONS

Different working time characteristics were associated with work-related mental health (i.e. burnout) as well as general mental health (i.e. depressive symptoms). Work intensity was associated with the prevalence of burnout symptoms and the results suggest that the mechanism may be through the need for recovery from the psychosocial exposures of work. Both schedule control and predictability were associated with depressive symptoms and the results suggest that work-life imbalance and lack of recovery may be implicated. Comprehensive prevention policies that consider work organization along with the psychosocial work environment and work-life balance may help to improve workers' mental health.

Using Behavioral Theory to Enhance Occupational Safety and Health: Applications to Health Care Workers

Work-related morbidity and mortality are persistent public health problems across all US industrial sectors, including health care. People employed in health care and social services are at high risk for experiencing injuries and illnesses related to their work. Social and behavioral science theories can be useful tools for designing interventions to prevent workplace injuries and illnesses and can provide a roadmap for investigating the multilevel factors that may hinder or promote worker safety and health. Specifically, individual-level behavioral change theories can be useful in evaluating the proximal, person-related antecedents (such as perceived behavioral control) that influence work safety outcomes. This article (1) provides a brief overview of widely used, individual-level behavior change theories and examples of their application to occupational safety and health (OSH)-related interventions that involve the health care community; (2) introduces an integrated theory of behavior change and its application to promoting the OSH of health care workers; and (3) discusses opportunities for application of individual-level behavior change theory to OSH research and practice activities involving health care workers. The use of behavioral science to consider the role of individual behaviors in promoting health and preventing disease and injury provides a necessary complement to structural approaches to protecting workers in the health care industry.

Evolving Science and Practice of Risk Assessment

Managing public health risks from environmental contaminants has historically relied on a risk assessment process defined by the regulatory context in which these risks are assessed. Risk assessment guidance follows a straightforward, chemical-by-chemical approach to inform regulatory decisions around the question "what is the risk-based concentration protective of human and ecological health outcomes?" Here we briefly summarize regulatory risk assessment in the context of innovative risk assessment approaches based on an evolving understanding of the underlying scientific disciplines that support risk analysis more broadly. We discuss scientific versus regulatory tensions in the application of these approaches for future risk assessments, and challenges in translating our improved understanding of the underlying scientific complexity to the regulatory landscape to better inform decision making that extends beyond conventional regulatory mandates.

The future of research on work, safety, health and wellbeing: A guiding conceptual framework

Work plays a central role in health. A conceptual model can help frame research priorities and questions to explore determinants of workers' safety, health, and wellbeing. A previous conceptual model focused on the workplace setting to emphasize the role of conditions of work in shaping workers' safety, health and wellbeing. These conditions of work include physical, organizational, and psychosocial factors. This manuscript presents and discusses an updated and expanded conceptual model, placing the workplace and the conditions of work within the broader context of socio-political-economic environments and consequent trends in employment and labor force patterns. Social, political and economic trends, such as growing reliance on technology, climate change, and globalization, have significant implications for workers' day-to-day experiences. These structural forces in turn shape employment and labor patterns, with implications for the availability and quality of jobs; the nature of relationships between employers and workers; and the benefits and protections available to workers. Understanding these patterns will be critical for anticipating the consequences of future changes in the conditions of work, and ultimately help inform decision-making around policies and practices intended to protect and promote worker safety, health, and wellbeing. This model provides a structure for anticipating research needs in response to the changing nature of work, including the formation of research priorities, the need for expanded research methods and measures, and attention to diverse populations of enterprises and workers. This approach anticipates changes in the way work is structured, managed, and experienced by workers and can effectively inform policies and practices needed to protect and promote worker safety, health and wellbeing.

A Cumulative Risk Perspective for Occupational Health and Safety (OHS) Professionals

Cumulative risk assessment (CRA) addresses the combined risk associated with chemical and non-chemical exposures. Although CRA approaches are utilized in environmental and ecological contexts, they are rarely applied in workplaces. In this perspectives article, we strive to raise awareness among occupational health and safety (OHS) professionals and foster the greater adoption of a CRA perspective in practice. Specifically, we provide an overview of CRA literature as well as preliminary guidance on when to consider a CRA approach in occupational settings and how to establish reasonable boundaries. Examples of possible workplace co-exposures and voluntary risk management actions are discussed. We also highlight important implications for workplace CRA research and practice. In particular, future needs include simple tools for identifying combinations of chemical and non-chemical exposures, uniform risk management guidelines, and risk communication materials. Further development of practical CRA methods and tools are essential to meet the needs of complex and changing work environments.

Work-related injuries, postural stress, and musculoskeletal disorders among the railway track maintainers in India

The main aim of this cross-sectional study was to evaluate work-related injuries (WRI) and the self-reported musculoskeletal symptoms among 742 railway track maintainers. The second aim of this study was to investigate the potential factors related to the prevalence of musculoskeletal disorders (MSDs) in track maintainers. This study also tried to do planning and implementing ergonomic intervention programs to improve track maintainer’s health. Modified Nordic questionnaires were administered to assess the prevalence of MSDs. Detailed posture analysis by rapid entire body assessment (REBA) method was performed to assess the risk level of concerned postures. The injury data for 12 months were collected by conducting a survey and personal interviews with the affected railway track maintainers. To assess the prevalence of MSDs, the odds ratio and 95% confidence interval were computed along with critical χ 2 values. Analysis of variance was performed to determine significant differences between the MSD present and absent among the track maintainers of the Indian railway. The result of this study showed that neglect of safety precautions is the main reason for injury, followed by slipping and falling and lack of awareness. Sprain injury is one of the main injuries, followed by cut, snakebite, abrasion, and fracture. Low educational levels of workers are also reasons for WRI. In conclusion, the prevalence and severity of MSD, particularly in the low back, knees, wrist, and shoulder and WRI were found to be very high among the track maintainers. The recommendations of this research are ergonomic interventions, such as track maintainers proper training, following the National Institute of Occupational Safety and Health -recommended weight limit for manual material handling, modification in hand tools, job rotation, performing stretching exercise, and avoiding awkward and static posture are needed.

Occupational health and safety hazards faced by healthcare professionals in Taiwan: A systematic review of risk factors and control strategies

Background

Healthcare professionals in Taiwan are exposed to a myriad of occupational health and safety hazards, including physical, biological, chemical, ergonomic, and psychosocial hazards. Healthcare professionals working in hospitals and healthcare facilities are more likely to be subjected to these hazards than their counterparts working in other areas.

Objectives

This review aims to assess current research literature regarding this situation with a view to informing policy makers and practitioners about the risks of exposure and offer evidence-based recommendations on how to eliminate or reduce such risks.

Methods

Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses review strategy, we conducted a systematic review of studies related to occupational health and safety conducted between January 2000 and January 2019 using MEDLINE (Ovid), PubMed, PMC, TOXLINE, CINAHL, PLOS One, and Access Pharmacy databases.

Results

The review detected 490 studies addressing the issue of occupational health and safety hazards; of these, 30 articles were included in this systematic review. These articles reported a variety of exposures faced by healthcare professionals. This review also revealed a number of strategies that can be adopted to control, eliminate, or reduce hazards to healthcare professionals in Taiwan.

Conclusion

Hospitals and healthcare facilities have many unique occupational health and safety hazards that can potentially affect the health and performance of healthcare professionals. The impact of such hazards on healthcare professionals poses a serious public health issue in Taiwan; therefore, controlling, eliminating, or reducing exposure can contribute to a stronger healthcare workforce with great potential to improve patient care and the healthcare system in Taiwan. Eliminating or reducing hazards can best be achieved through engineering measures, administrative policy, and the use of personal protective equipment.

Implications

This review has research, policy, and practice implications and provides future students and researchers with information on systematic review methodologies based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses strategy. It also identifies occupational health and safety risks and provides insights and strategies to address them.

Defining 'Integration' for Total Worker Health®: A New Proposal

The effects of work and the conditions of employment on health behaviors and intermediate health conditions have been demonstrated, to the extent that these relationships should be addressed in efforts to prevent chronic disease. However, conventional health promotion practice generally focuses on personal risk factors and individual behavior change. In an effort to find solutions to the myriad of health challenges faced by the American workforce, the U.S. National Institute for Occupational Safety and Health (NIOSH) established the Total Worker Health® (TWH) program. Originally organized around the paradigm of integrating traditional occupational safety and health protections with workplace health promotion, TWH has evolved to a broader emphasis on workplace programs for enhancing worker safety, health, and well-being. Among the research programs and approaches developed by investigators at NIOSH Centers of Excellence for TWH and elsewhere, definitions of 'integration' in workplace interventions vary widely. There is no consensus about which organizational or individual outcomes are the most salient, how much to emphasize organizational contexts of work, or which program elements are necessary in order to qualify as 'Total Worker Health'. Agreement about the dimensions of integration would facilitate comparison of programs and interventions which are self-defined as TWH, although diverse in content. The specific criteria needed to define integration should be unique to that concept-i.e. distinct from and additive to conventional criteria for predicting or evaluating the success of a workplace health program. We propose a set of four TWH-specific metrics for integrated interventions that address both program content and process: (i) coordination and interaction of workplace programs across domains; (ii) assessment of both work and non-work exposures; (iii) emphasis on interventions to make the workplace more health-promoting; and (iv) participatory engagement of workers in pivotal ways during intervention prioritization and planning to develop self-efficacy in addressing root causes, skill transfer, building program ownership, empowerment, and continuous improvement. Thus we find that integration requires organizational change, both to engage two managerial functions with different goals, legal responsibilities, and (often) internal incentives & resources, and also to orient the organization toward salutogenesis. Examples from research activity within the Center for the Promotion of Health in the New England Workplace illustrate how these criteria have been applied in practice.

Inhalation of welding fumes reduced sperm counts and high fat diet reduced testosterone levels; differential effects in Sprague Dawley and Brown Norway rats

Background

Previous studies have shown that inhalation of welding fumes may induce pulmonary and systemic inflammation and organ accumulation of metal, to which spermatogenesis and endocrine function may be sensitive. Also obesity may induce low-grade systemic inflammation. This study aimed to investigate the effects on sperm production of inhaled metal nanoparticles from stainless steel welding, and the potential exacerbation by intake of a high fat diet. Both the inbred Brown Norway and the outbred Sprague Dawley rat strains were included to study the influence of strain on the detection of toxicity. Rats were fed regular or high fat (HF) diet for 24 weeks and were exposed to 20 mg/m³ of gas metal arc-stainless steel (GMA-SS) welding fumes or filtered air for 3 h/day, 4 days/week for 5 weeks, during weeks 7–12. Outcomes were assessed upon termination of exposure (week 12) and after recovery (week 24).

Results

At week 12, the GMA-SS exposure induced pulmonary inflammation in both strains, without consistent changes in markers of systemic inflammation (CRP, MCP-1, IL-6 and TNFα). GMA-SS exposure lowered daily sperm production compared to air controls in Sprague Dawley rats, but only in GMA-SS Brown Norway rats also fed the HF diet. Overall, HF diet rats had lower serum testosterone levels compared to rats on regular diet. Metal content in the testes was assessed in a limited number of samples in Brown Norway rats, but no increase was obsedrved. At week 24, bronchoalveolar lavage cell counts had returned to background levels for GMA-SS exposed Sprague Dawley rats but remained elevated in Brown Norway rats. GMA-SS did not affect daily sperm production statistically significantly at this time point, but testicular weights were lowered in GMA-SS Sprague Dawley rats. Serum testosterone remained lowered in Sprague Dawley rats fed the HF diet.

Conclusion

Exposure to GMA-SS welding fumes lowered sperm production in two strains of rats, whereas high fat diet lowered serum testosterone. The effect on sperm counts was likely not mediated by inflammation or lowered testosterone levels. The studied reproductive outcomes seemed more prone to disruption in the Sprague Dawley compared to the Brown Norway strain.

Toward an Expanded Focus for Occupational Safety and Health: A Commentary

Powerful and ongoing changes in how people work, the workforce, and the workplace require a more holistic view of each of these. We argue that an expanded focus for occupational safety and health (OSH) is necessary to prepare for and respond rapidly to future changes in the world of work that will certainly challenge traditional OSH systems. The WHO Model for Action, various European efforts at well-being, and the Total Worker Health concept provide a foundation for addressing changes in the world of work. However, a paradigm expansion to include the recognition of worker and workforce well-being as an important outcome of OSH will be needed. It will also be vital to stimulate transdisciplinary efforts and find innovative ways to attract and train students into OSH professions as the paradigm expands. This will require active marketing of the OSH field as vibrant career choice, as a profession filled with meaningful, engaging responsibilities, and as a well-placed investment for industry and society. An expanded paradigm will result in the need for new disciplines and specialties in OSH, which may be useful in new market efforts to attract new professionals. Ultimately, to achieve worker and workforce well-being we must consider how to implement this expanded focus.

Heat Exposure and Occupational Injuries: Review of the Literature and Implications

PURPOSE OF REVIEW

The burden of heat-related adverse occupational health effects, as well as traumatic injuries, is already substantial. Projected increases in mean temperatures and extreme events may increase the risk of adverse heat health effects and enhance disparities among exposed workers. This article reviews the emerging literature on the relationship between heat exposure and occupational traumatic injuries and discusses implications of this work.

RECENT FINDINGS

A recent meta-analysis of three case-crossover and five time series studies in industrialized settings reported an association of increasing occupational injuries with increasing heat exposure, with increased effect estimates for male gender and age less than 25 years, although heterogeneity in exposure metrics and sources of bias were demonstrated to varying degrees across studies. A subsequent case-crossover study in outdoor construction workers reported a 0.5% increase in the odds of traumatic injuries per 1 °C increase in maximum daily humidex (odds ratio 1.005 [95% CI 1.003-1.007]). While some studies have demonstrated reversed U-shaped associations between heat exposure and occupational injuries, different risk profiles have been reported in different industries and settings. Studies conducted primarily in industrialized settings suggest an increased risk of traumatic injury with increasing heat exposure, though the exact mechanisms of heat exposure's effects on traumatic injuries are still under investigation. The effectiveness of heat-related injury prevention approaches has not yet been established. To enhance the effectiveness of prevention efforts, prioritization of approaches should take into account not only the hierarchy of controls, social-ecological models, community and stakeholder participation, and tailoring of approaches to specific local work settings, but also methods that reduce local and global disparities and better address the source of heat exposure, including conservation-informed land-use planning, built environment, and prevention through design approaches. Participation of occupational health experts in transdisciplinary development and integration of these approaches is needed.

Employee Perceptions of Safety, Health, and Well-Being: Focus Group Findings From One Veterans Affairs Medical Center

OBJECTIVE

Focus groups were conducted at one veterans affairs (VA) medical center to understand (1) how the work environment and conditions of work influence employee safety, health, and well-being; (2) what programs, policies, and practices promote and protect employee safety and health in VA; and (3) how employee safety, health, and well-being impact the organizational mission.

METHODS

Nine focus groups were conducted with leadership, supervisor, and frontline employees. Focus groups were audio recorded, transcribed, and content analysis was performed.

RESULTS

Fifty-five employees participated in the focus groups. Six common themes emerged-stressful working conditions, health hazards, organizational factors, current program knowledge, participation barriers, and program suggestions.

CONCLUSIONS

Employees identified organizational and structural elements of work that impact safety, health, and well-being. Application of the Total Worker Health™ hierarchy of controls provided a novel framework for discussion of focus group findings.

Framework for Considering Productive Aging and Work

OBJECTIVES

The U.S. population is experiencing a demographic transition resulting in an aging workforce. The objective of this article is to elucidate and expand an approach to keep that workforce safe, healthy, and productive.

METHODS

This article elucidates the framework for the National Center for Productive Aging at Work of the National Institute for Occupational Safety and Health. Subject matter experts used a snowball method to review published literature to substantiate elements in the framework.

RESULTS

Evidence-based literature supports a productive aging framework for the workforce involving the following elements: 1) life span perspective; 2) comprehensive and integrated approaches to occupational safety and health; 3) emphasis on positive outcomes for both workers and organizations; and 4) supportive work culture for multigenerational issues.

CONCLUSION

The productive aging framework provides a foundational and comprehensive approach for addressing the aging workforce.

Suicide and drug-related mortality following occupational injury

BACKGROUND

Drug overdoses and suicides have been rising since 2000 and are major contributors to a 3-year decline in US life expectancy. Studies suggest that injured workers have elevated rates of depression and opioid use, but no studies have measured excess mortality related to these risks.

MATERIALS AND METHODS

We linked New Mexico workers' compensation data for 100 806 workers injured in 1994 through 2000 with Social Security Administration earnings and mortality data through 2013 and National Death Index cause of death data. We then estimated the association between receiving lost-time workers' compensation benefits and mortality hazard ratios (HRs) and 95% confidence intervals (CIs) based on Fine and Gray cause-specific subdistribution hazards for common causes of death and for drug-related, suicide, and alcohol-related mortality.

RESULTS

There was almost a 3-fold increase in combined drug-related and suicide mortality hazard among women (HR = 2.63, 95% CI = 1.91-3.64) and a substantial increase among men (HR = 1.42, 95% CI = 1.13-1.79). Circulatory disease mortality hazard was elevated for men (HR = 1.25, 95% CI = 1.05-1.50).

CONCLUSION

Workplace injuries severe enough to require more than a week off work may impair workers' long-term health and well-being. Drug-related deaths and suicides may be important contributors to the long-term excess mortality of injured workers. Improved workplace conditions, improved pain treatment, better treatment of substance use disorders, and treatment of postinjury depression may substantially reduce mortality consequent to workplace injuries.

Development and implementation of evidence-based laboratory safety management tools for a public health laboratory

We developed an evidence-based continuous quality improvement (CQI) cycle for laboratory safety as a method of utilizing survey data to improve safety in a public health laboratory setting. • Expert Opinion: The CQI cycle begins with the solicitation of laboratory staff input via an annual survey addressing potential chemical, physical and radiological hazards associated with multiple laboratory activities. The survey collects frequency, severity and exposure data related to these activities in the context of the most pathogenic organisms handled at least weekly. • Gap Analysis: Step 2 of the CQI cycle used survey data to identify areas needing improvement. Typically, the traditional two-dimensional risk assessment matrix is used to prioritize mitigations. However, we added an additional dimension - frequency of exposure - to create three-dimensional risk maps to better inform and communicate risk priorities. • Mitigation Measures: Step 3 of the CQI cycle was to use these results to develop mitigations. This included evaluating the identified risks to determine what risk control measures (elimination, substitution, engineering, administrative or PPE) were needed. In the 2016 iteration of the CQI cycle described here, all mitigations were based on administrative controls. • Evaluation and Feedback: The last step of the CQI cycle was to evaluate the inferred effects of interventions through subsequent surveys, allowing for qualitative assessment of intervention effectiveness while simultaneously restarting the cycle by identifying new hazards. Here we describe the tools used to drive this CQI cycle, including the survey tool, risk analysis method, design of interventions and inference of mitigation effectiveness.

Assessing Workplace Health and Safety Strategies, Trends, and Barriers through a Statewide Worksite Survey

Chronic diseases have added to the economic burden of the U.S. healthcare system. Most Americans spend most of their waking time at work, thereby, presenting employers with an opportunity to protect and promote health. The purpose of this study was to assess the implementation of workplace health governance and safety strategies among worksites in the State of Nebraska, over time and by industry sector using a randomized survey. Weighted percentages were compared by year, industry sector, and worksite size. Over the three study periods, 4784 responses were collected from worksite representatives. Adoption of workplace health governance and planning strategies increased over time and significantly varied across industry sector groups. Organizational safety policies varied by industry sector and were more commonly reported than workplace health governance and planning strategies. Time constraints were the most common barrier among worksites of all sizes, and stress was reported as the leading employee health issue that negatively impacts business. Results suggest that opportunities exist to integrate workplace health and safety initiatives, especially in blue-collar industry sectors and small businesses.

Need for a new workplace safety and health (WSH) strategy for the fourth Industrial Revolution

We are on the cusp of the fourth Industrial Revolution which promises to revolutionize the way we live and work. Throughout history, as society and technology progress, so too have our workplace safety and health (WSH) strategies in regard to better knowledge and enhanced regulation. In this paper, we argue for a new WSH 4.0 strategy which requires us to adopt an adaptive and highly responsive approach to promote Total Worker Health in the face of rapid technological advancements and changes in employment relationships. To do so, we propose a multi-pronged strategy comprising (i) adaptive WSH solutions in regard to surveillance, risk assessment, and control measures leveraging on new technologies; (ii) effective multi-stakeholder dialogues for collaborative and sustainable solutions; (iii) an anticipatory WSH governance framework based upon shared values and cooperative responsibility; and (iv) professional development among WSH practitioners. This new WSH 4.0 strategy will enable WSH professionals to remain effective in this coming Industrial Revolution.

Risk Factors and Mechanisms Underlying Cross-Shift Decline in Kidney Function in Guatemalan Sugarcane Workers

OBJECTIVE

Identify early biomarkers and mechanisms of acute kidney injury in workers at risk of developing chronic kidney disease of unknown origin (CKDu).

METHODS

We assessed cross-shift changes in kidney function and biomarkers of injury in 105 healthy sugarcane workers. We obtained pre-harvest clinical data as well as daily environmental, clinical, and productivity data for each worker.

RESULTS

The average percent decline in cross-shift estimated glomerular filtration rate (eGFR) was 21.8% (standard deviation [SD] 13.6%). Increasing wet bulb globe temperature (WBGT), high uric acid, decreased urine pH, urinary leukocyte esterase, and serum hyperosmolality were risk factors for decline in kidney function.

CONCLUSIONS

Sugarcane workers with normal kidney function experience recurrent subclinical kidney injury, associated with elevations in biomarkers of injury that suggest exposure to high temperatures and extreme physical demands.

Larger Workplaces, People-Oriented Culture, and Specific Industry Sectors Are Associated with Co-Occurring Health Protection and Wellness Activities

Employers are increasingly interested in offering workplace wellness programs in addition to occupational health and safety (OHS) activities to promote worker health, wellbeing, and productivity. Yet, there is a dearth of research on workplace factors that enable the implementation of OHS and wellness to inform the future integration of these activities in Canadian workplaces. This study explored workplace demographic factors associated with the co-implementation of OHS and wellness activities in a heterogenous sample of Canadian workplaces. Using a cross-sectional survey of 1285 workplaces from 2011 to 2014, latent profiles of co-occurrent OHS and wellness activities were identified, and multinomial logistic regression was used to assess associations between workplace demographic factors and the profiles. Most workplaces (84%) demonstrated little co-occurrence of OHS and wellness activities. Highest co-occurrence was associated with large workplaces (odds ratio (OR) = 3.22, 95% confidence interval (CI) = 1.15⁻5.89), in the electrical and utilities sector (OR = 5.57, 95% CI = 2.24⁻8.35), and a high people-oriented culture (OR = 4.70, 95% CI = 1.59⁻5.26). Promoting integrated OHS and wellness approaches in medium to large workplaces, in select industries, and emphasizing a people-oriented culture were found to be important factors for implementing OHS and wellness in Canadian organizations. Informed by these findings, future studies should understand the mechanisms to facilitate the integration of OHS and wellness in workplaces.

Effect of a Job Demand-Control-Social Support Model on Accounting Professionals' Health Perception

The Job Demand-Control and Job Demand-Control-Support (JDCS) models constitute the theoretical approaches used to analyze the relationship between the characteristics of labor and occupational health. Few studies have investigated the main effects and multiplicative model in relation to the perceived occupational health of professional accountants. Accountants are subject to various types of pressure in performing their work; this pressure influences their health and, ultimately, their ability to perform a job well. The objective of this study is to investigate the effects of job demands on the occupational health of 739 accountants, as well as the role of the moderator that internal resources (locus of control) and external resources (social support) have in occupational health. The proposed hypotheses are tested by applying different models of neural networks using the algorithm of the Extreme Learning Machine. The results confirm the relationship between certain stress factors that affect the health of the accountants, as well as the direct effect that the recognition of superiors in occupational health has. Additionally, the results highlight the moderating effect of professional development and the support of superiors on the job’s demands.

Combating toxic workplace environment

Purpose

Across the globe, every organization is striving to enhance the productivity and growth rate, but the prosperity and success of an organization is determined by the type of work environment in which it operates. To address this apprehension, this paper aims to determine the effect of toxic workplace environment on job stress that can badly affect the job productivity of an employee.

Design/methodology/approach

As an independent variable, toxic workplace environment was used as a complete spectrum consisting multiple dimensions named as workplace ostracism, workplace incivility, workplace harassment and workplace bullying. Job stress was used as a mediating variable between the spectrum of toxic workplace environment and job productivity. In this regard, self-administered close-ended questionnaire was used to collect the data from 267 employees of the health sector (HS) of Lahore region in Pakistan. For analysis purpose, we used confirmatory factor analysis to ensure the convergent and discriminant validity of the factors. AMOS 22 was used to check the direct and indirect effect of selected variables. Hayes mediation approach was used to check the mediating role of job stress between four dimensions of toxic workplace environment and job productivity.

Findings

The output demonstrated that the dimensions of toxic workplace environment have a negative significant relationship with job productivity, while job stress was proved as a statistical significant mediator between dimensions of toxic workplace environment and job productivity. Finally, we conclude that organizations need to combat/cleanse the roots of toxic workplace environment to ensure their prosperity and success.

Originality/value

This study aims to determine the effect of toxic workplace environment on job stress that can badly affect the job productivity of an employee. An empirical study in the context of the HS of Pakistan. This study, which is based on HS, has never been reported before in literature.

A longitudinal study of work-related injuries: comparisons of health and work-related consequences between injured and uninjured aging United States adults

Background

Age may affect one’s susceptibility to the myriad physical hazards that may pose risks for work-related injuries. Aging workers are not only at risk for work-related injuries but, also, at even higher risk for more severe health and work-related consequences. However, limited longitudinal research efforts have focused on such injuries among the aging workforce. This study aimed to investigate the association between physical work-related factors and injuries among United States (U.S.) workers, and then compare the injured and uninjured workers with regard to consequences including, functional limitations, and reduced working hours post injury. A cohort of 7212 U.S. workers aged 50 years and above from the U.S. Health and Retirement Study were retrospectively followed from 2004 to 2014. Data on exposures were lagged by one survey wave prior to the outcome of work-related injuries and consequences, respectively. Crude and adjusted incident rate ratios, and hazard ratios were estimated using generalized estimating equations and Cox models.

Results

Risk of experiencing a work-related injury event was over two times greater among those whose job had work requirements for physical effort, lifting heavy loads, and stooping/kneeling/crouching, compared to those who did not. Over time, injured compared to uninjured workers had higher risks of functional limitations and working reduced hours.

Conclusions

The aging workforce is at a high risk of experiencing injuries. Further, injured adults were not only more likely to incur a disability prohibiting daily life-related activities, over time, but, also, were more likely to work reduced hours. It will be important to consider accommodations to minimize functional limitations that may impair resulting productivity.

[Factors involved in job insecurity and their relationship with the health of salaried workers and contract workers in BoliviaRelação entre condições precárias de trabalho e a saúde dos trabalhadores assalariados e contratados na Bolívia]

OBJECTIVE

To examine the association between factors involved in job insecurity and: health service use, tobacco use, and alcohol use among salaried workers and contract workers in Bolivia.

METHODS

A cross-sectional study was performed with a sample of workers composed of 1203 women and 1780 men between the ages of 14 and 65 years using data from Bolivia's 2015 Household Survey. The dependent variables were health service use, tobacco use, and alcohol use; the independent variables were wages, type of contract, work hours, and exercise of workers' rights. Prevalence rates were calculated and the association between factors involved in job insecurity and the dependent variables was assessed using multivariate binomial regression models with adjustment for sociodemographic variables. The analyses were stratified by sex.

RESULTS

The adjusted models showed a significant association between working under a temporary contract and lower use of health services among men (odds ratio [OR]: 0.70; 95% confidence interval [95% CI]: 0.56-0.87) and women (OR: 0.62; 95% CI: 0.46-0.82). Poor exercise of workers' rights was also associated with lower use of health services (OR: 0.61; IC 95%: 0.45-0.83) among men. Long work hours showed an association with greater use of alcohol among women (OR: 1.75; 95% CI: 1.34-2.29). Low wages were associated with lower tobacco use among men (OR: 0.75; 95% CI: 0.57-0.99) and women (OR; 0.57; 95% CI: 0.33-0.99). However, being a manual worker was associated with tobacco use (OR: 1.36; 95% CI: 1.09-1.70) among men.

CONCLUSIONS

Having a temporary contract and belonging to income quintile I (the poorest) are both associated with lower use of health services and lower probability of smoking in individuals of either sex. Long work hours are associated with greater alcohol use among women. Poor exercise of workers' rights is associated with lower use of health services among men.

Characterizing the Interrelationships of Prescription Opioid and Benzodiazepine Drugs With Worker Health and Workplace Hazards

OBJECTIVE

Prescription opioid and benzodiazepine drug use, which has risen significantly, can affect worker health. Exploration of the scientific literature assessed (1) interrelationships of such drug use, occupational risk factors, and illness and injury, and (2) occupational and personal risk factor combinations that can affect their use.

METHODS

The scientific literature from 2000 to 2015 was searched to determine any interrelationships.

RESULTS

Evidence for eight conceptual models emerged based on the search yield of 133 articles. These models summarize interrelationships among prescription opioid and benzodiazepine use with occupational injury and illness. Factors associated with the use of these drugs included fatigue, impaired cognition, falls, motor vehicle crashes, and the use of multiple providers.

CONCLUSION

Prescription opioid and benzodiazepine drugs may be both a personal risk factor for work-related injury and a consequence of workplace exposures.

Implications of applying cumulative risk assessment to the workplace

Multiple changes are influencing work, workplaces and workers in the US including shifts in the main types of work and the rise of the 'gig' economy. Work and workplace changes have coincided with a decline in unions and associated advocacy for improved safety and health conditions. Risk assessment has been the primary method to inform occupational and environmental health policy and management for many types of hazards. Although often focused on one hazard at a time, risk assessment frameworks and methods have advanced toward cumulative risk assessment recognizing that exposure to a single chemical or non-chemical stressor rarely occurs in isolation. We explore how applying cumulative risk approaches may change the roles of workers and employers as they pursue improved health and safety and elucidate some of the challenges and opportunities that might arise. Application of cumulative risk assessment should result in better understanding of complex exposures and health risks with the potential to inform more effective controls and improved safety and health risk management overall. Roles and responsibilities of both employers and workers are anticipated to change with potential for a greater burden of responsibility on workers to address risk factors both inside and outside the workplace that affect health at work. A range of policies, guidance and training have helped develop cumulative risk assessment for the environmental health field and similar approaches are available to foster the practice in occupational safety and health.

[Musculoskeletal pain among bus drivers and fare collectors in the Metropolitan Region of Belo Horizonte, Brazil]

Musculoskeletal pain among professionals in the transport sector has been linked to working conditions. The scope of this study was to assess the prevalence of cervical musculoskeletal pain and its relation to pain in other areas (arms, hands and shoulders). The association between neck pain, related to pain in other areas or otherwise, was checked against occupational factors. A cross-sectional, descriptive and analytical study was conducted with 799 bus drivers and 708 fare collectors of the Metropolitan Region of Belo Horizonte, Brazil. The outcome was characterized according to the positive answer to the question about musculoskeletal pain in the anatomical areas studied. The prevalence of neck pain in the sample was highest at 16.3%, followed by pain in the shoulders 15.4%, arms 13.3% and hands 6.3%. The factors associated with musculoskeletal pain in the sample were being female, complaints of disability, perception of threat to safety, vibration, excessive or unbearable noise and sitting in an uncomfortable posture. The results provide clues to transformation of the workplace, thereby contributing to the enhancement of occupational health.

Decreasing Physical Inactivity in the Veterans Health Administration Employee Population

OBJECTIVE

The aim of this study was to describe a comprehensive approach to decrease physical inactivity in the Veterans Health Administration (VHA) employee population.

METHODS

The approach included (1) initiatives to decrease physical inactivity in the workplace; (2) two operational surveys to assess system-wide service provision; and (3) two national employee surveys.

RESULTS

From 2010 to 2012, 86 employee fitness centers were completed in VA medical centers. A grants program (2010 to 2015) funded smaller projects designed to decrease physical inactivity in the workplace. Projects involved the provision of equipment to decrease sedentary behaviors, including stability balls, treadmill and sit-to-stand desks, stairwell projects, and funding for on-site fitness classes, bicycle racks, and outdoor par courses and walking paths among others.

CONCLUSIONS

A comprehensive approach to decrease physical inactivity in VHA employees was successful. Overall, self-reported, age-adjusted physical inactivity in VHA employees decreased from 25.3% in 2010 to 16.1% in 2015.

Work, Health, And Worker Well-Being: Roles And Opportunities For Employers

Work holds the promise of supporting and promoting health. It also carries the risk of injury, illness, and death. In addition to harms posed by traditional occupational health hazards, such as physically dangerous workplaces, work contributes to health problems with multifactorial origins such as unhealthy lifestyles, psychological distress, and chronic disease. Not only does work affect health, but the obverse is true: Unhealthy workers are more frequently disabled, absent, and less productive, and they use more health care resources, compared to their healthy colleagues. The costs of poor workforce health are collectively borne by workers, employers, and society. For business as well as altruistic reasons, employers may strive to cost-effectively achieve the safest, healthiest, and most productive workforce possible. Narrowly focused health goals are giving way to a broader concept of employee well-being. This article explores the relationship between health and work, outlines opportunities for employers to make this relationship health promoting, and identifies areas needing further exploration.

Mortality and Morbidity during Extreme Heat Events and Prevalence of Outdoor Work: An Analysis of Community-Level Data from Los Angeles County, California

Heat is a well-recognized hazard for workers in many outdoor settings, yet few investigations have compared the prevalence of outdoor work at the community level and rates of heat-related mortality and morbidity. This analysis examines whether heat-related health outcomes occur more frequently in communities with higher proportions of residents working in construction, agriculture, and other outdoor industries. Using 2005–2010 data from Los Angeles County, California, we analyze associations between community-level rates of deaths, emergency department (ED) visits, and hospitalizations during summer heat events and the prevalence of outdoor work. We find generally higher rates of heat-related ED visits and hospitalizations during summer heat events in communities with more residents working outdoors. Specifically, each percentage increase in residents working in construction resulted in an 8.1 percent increase in heat-related ED visits and a 7.9 percent increase in heat-related hospitalizations, while each percentage increase in residents working in agriculture and related sectors resulted in a 10.9 percent increase in heat-related ED visits. The findings suggest that outdoor work may significantly influence the overall burden of heat-related morbidity at the community level. Public health professionals and healthcare providers should recognize work and employment as significant heat risk factors when preparing for and responding to extreme heat events.

Integrated Employee Occupational Health and Organizational-Level Registered Nurse Outcomes

OBJECTIVE

The study examined organizational culture, structural supports, and employee health program integration influence on registered nurse (RN) outcomes.

METHODS

An organizational health survey, employee health clinical operations survey, employee attitudes survey, and administration data were collected. Multivariate regression models examined outcomes of sick leave, leave without pay, voluntary turnover, intention to leave, and organizational culture using 122 medical centers.

RESULTS

Lower staffing ratios were associated with greater sick leave, higher turnover, and intention to leave. Safety climate was favorably associated with each of the five outcomes. Both onsite employee occupational health services and a robust health promotion program were associated with more positive organizational culture perceptions.

CONCLUSIONS

Findings highlight the positive influence of integrating employee health and health promotion services on organizational health outcomes. Attention to promoting employee health may benefit organizations in multiple, synergistic ways.

From Policy to Practice: Tobacco Use Cessation for Employees in the Veterans Health Administration

OBJECTIVE

To describe a comprehensive approach to increase tobacco use cessation in the Veterans Health Administration (VHA) employee population.

METHODS

The approach included: 1) national policy; 2) a pilot tobacco use cessation program; and 3) two operational surveys to assess system-wide tobacco use cessation service provision.

RESULTS

The proportion of VHA facilities offering a comprehensive tobacco use cessation program increased from 51% in 2010 to 72% in 2014, with 83% of facilities providing nicotine replacement therapy to employees. The WIN by Quitting Tobacco program was successful; employees who participated in the pilot program quit tobacco at high rates (64% at 1 month post quit date).

CONCLUSIONS

From policy to practice, the comprehensive approach to tobacco use cessation in VHA was successful and may serve as a model for future workplace health promotion and occupational safety and health initiatives.
