Messing Keywords: Pressure-pain threshold; Standing; Sitting; Working posture; Arterial blood pressure; Pain; Sex differences Abstract: North American workers usually stand while working, and prolonged standing is associated with discomfort and cardiovascular problems. Since prolonged sitting is also associated with health problems, and standing postures differ as to mobility and access to seating, it is desirable to identify an optimal mix of postures. As a step towards this identification, it is desirable to develop indicators of potential health effects that respond to changes in work requirements. We observed 65 subjects who usually stood at work, in four types of workplaces. Pressure-pain threshold (PPT) recorded on the plantar surface was used as an indicator of discomfort and arterial blood pressure was used as an indicator of cardiovascular effects. PPT after work was significantly lower than that before work. Sitting for even a small part of the day appeared to be protective. The effects of static vs. dynamic work on PPT and arterial blood pressure may differ.

A study describes self-reported usual working postures in a population and their associations with other working conditions and demographic variables. The analyses in the study conducted were limited to respondents with paid employment who had at least 6 months seniority in their current jobs, comprising 9,425 subjects.

Objective: Workers' attempts to accommodate family needs may be considered illegitimate in the paid work sphere. Their attempts at work-family balancing (WFB) in that sphere can remain invisible, even when those attempts require considerable energy. Since identification of WFB strategies can potentially lead to suggestions to improve management practices, we report an attempt to find them in the work sphere. Participants: 14 care aides in a Québec residence for seniors and 2~schedule managers were recruited. Methods: Qualitative ergonomic analysis was employed. 24 hours observation; interviews of nursing and human resources staff; qualitative ergonomic analysis by two researchers; feedback collected from meetings with management and union. Strategies for schedule choice were compared between care aides with heavier vs. lighter family responsibilities. Results: For workers with heavier family responsibilities, choice of work schedules was almost entirely conditioned by family considerations, leaving little leeway to manage workers' own health protection. Conclusions: Family constraints affected activity at work, and strategies for handling family constraints could potentially be affected by changes in work organization. Managers should encourage full discussion of work-family balancing strategies if they wish to adapt their working conditions to the workers, and ergonomists should include this balancing as a facet of work activity, despite possible negative consequences.

Language barriers are often cited as a factor contributing to ethnic inequalities in occupational health; however, little information is available about the mechanisms at play. The authors describe the multiple ways in which language influences occupational health in a large garment factory employing many immigrants in Montreal. Between 2004 and 2006, individual, semi-structured interviews were conducted with 15 women and 10 men from 14 countries of birth. Interviews were conducted in French and English, Canada's official languages, as well as in non-official languages with the help of colleague-interpreters. Observation within the workplace was also carried out at various times during the project. The authors describe how proficiency in the official languages influences occupational health by affecting workers' ability to understand and communicate information, and supporting relationships that can affect work-related health. They also describe workers' strategies to address communication barriers and discuss the implications of these strategies from an occupational health standpoint. Along with the longer-term objectives of integrating immigrants into the linguistic majority and addressing structural conditions that can affect health, policies and practices need to be put in place to protect the health and well-being of those who face language barriers in the short term.

Women suffer many health problems related to their work, but attempts to improve their situation face obstacles at two levels: recognition of their problems and ability to organize to prevent them. Recognition by occupational health specialists has been delayed due in part to: A perception that women's issues have been included in research focussed on male workers; pressure to deal with more visible issues of mortality and well-established illness; ignorance of women's working conditions; methodological biases and inadequacies. Recognition by unions is slowed when women and their concerns are absent from union membership and/or governing structures. Feminist health advocates have not often participated in these struggles, due to social class differences and difficulties in linking with some male-dominated unions. Also, due to the wide variety of hazardous working conditions, they do not emerge from population-based analyses of health determinants in the same way as do domestic violence, tobacco or poverty. The authors describe three alliances necessary for successful research, policy and practice in women's occupational health: between feminist and working-class organizations; between feminists and occupational health scientists; between researchers and women workers.

Prolonged standing is described as uncomfortable by exposed workers, but the discomfort has not been linked to precise descriptions of workplace activity. We observed 10 sales and kitchen workers ("group 1") who worked standing. We compared the plantar pain-pressure threshold (PPT) of "group 1" (10 standing workers) to that of "group 2" (11 researchers who could choose their posture freely). Group 1 spent an average time of 62% standing still compared to 5% for group 2. Despite the fact that group 1 were primarily confined to defined areas and stood for 62% of the time, their mean time standing still was only 7 s. They walked 35% of the time, but 57% of walking sequences were only one or two steps. Group 1 PPT declined by 23% over the work day compared to 5% among group 2 (p < 0.05, ANOVA). Foot PPT is a promising quantitative indicator of effects of standing work. [ABSTRACT FROM AUTHOR]

Work is organized based in part on the perceptions, by managers and workers, of workers, their abilities and the characteristics of the work to be done. Physical tasks in factories and services have often been divided into 'light' and 'heavy', a division that often corresponds formally or informally to gender. We have observed the work of cleaners on wards and in offices in an acute-care hospital, using several indicators of workload to identify and characterize typical work situations. 'Heavy' work was characterized by neutral postures, walking, repetitive movements involving the articulations of the upper limb pushing a 1-6 kg (wet or dry) mop, with occasional more intense effort. 'Light' work was characterized by flexed postures, walking, rapid repetitive movements involving the articulations of the upper limb and light weights (dusting) or 1-3 kg weights (emptying wastebaskets), with more occasional intense effort. We did not discover any compelling reason to divide cleaning into 'light' and 'heavy' work. Task assignment by sex may appear to be a solution to excessive job demands which would be better addressed by job re-design. [ABSTRACT FROM AUTHOR]

Objective: Occupational health researchers have often treated gender as a confounder in epidemiologic studies, but gender may influence exposure profiles. This study investigated gender differences in occupational hazard exposures within the same occupation., Methods: We analyzed the 6 th Korean Working Conditions Survey (2020), a nationally representative dataset from South Korea. After restricting the study population to 22 511 full-time wage workers, we assessed 18 self-reported occupational exposures (4 physical, 4 chemical, 1 biological, 6 musculoskeletal, 3 psychosocial). To create matched samples, each man was matched with woman in the same occupational and industrial codes using `nearest neighbor matching` based on the propensity scores, considering age, education, employment status, the number of subordinates, and company size. This resulted in a matched study population of 3918 male and 3918 female workers in 403 occupations. Conditional logistic regression was applied to examine gender differences within the same occupation, adjusting for other covariates., Results: We found persistent gender differences in occupational hazard exposures, even after matching of men and women within the same occupation and industry based on propensity scores. Men reported a higher prevalence of exposure to physical (eg, loud noise) and chemical factors (eg, chemical products), while women were more likely to be exposed to psychosocial factors (eg, handling angry clients). The findings on musculoskeletal factors were mixed, with men being more exposed to standing and women to repetitive hand movements., Conclusions: Gender should be considered when planning interventions to reduce occupational harmful exposures, even within the same occupation.

Objective: Conducting participatory research (PR) aimed at improving health implies considering inequitable power relations, including those related to sex/gender (S/G). This necessitates specific skills and methods and may be challenging especially since guidelines are scarce. Our objective was to perform a scoping review to provide a typology of existing guidelines for researchers on how to take account of S/G in the context of PR in public health, with a focus on occupational and environmental health., Methods: All steps of the research were conducted with the collaboration of an advisory committee, following PR principles. Nineteen documents were retained from 513 references identified in nine scientific databases and grey literature between 2000 and 2020. Data on recommendations were extracted and coded qualitatively. Cluster analysis based on similarities in recommendations proposed in the documents identified four types: (1) empowerment-centered; (2) concrete action-centered; (3) macrosystem-centered; and (4) stakeholder-centered., Synthesis: Many sources gave pointers on how to include S/G during data collection and analysis or during the dissemination of findings, but there was a dearth of suggestions for building partnerships with stakeholders and producing sustainable S/G sociopolitical transformations. Occupational health PR showed less similarities with other public health subfields including environmental health PR. Power relationships with workplace stakeholders generated specific obstacles related to S/G integration that require further attention. Intersectionality and reflexive practices emerged as overarching themes., Conclusion: This review provides helpful guidelines to researchers at different stages of planning PR, ranging from familiarizing themselves with S/G approaches to anticipating difficulties in their ongoing S/G-transformative PR., (© 2023.

Taking account of sex and gender in occupational health studies poses statistical challenges. Other sociodemographic variables, such as racialization, class, and age, also affect the relations between workplace exposures and health and interact with sex and gender. Our objective was to perform a critical review of conventional and emerging statistical tools, examining whether each analysis takes account of sociodemographic variables (1) in a way that contributes to identification of critical occupational determinants of health (2) while taking account of relevant population characteristics to reflect intersectional approaches to health and (3) using sample sizes and population characteristics available to researchers. A two-step search was conducted: (1) a scientific watch concerning the statistical tools most commonly used in occupational health over the past 20 years; (2) a screening of the 1980-2022 literature with a focus on emerging tools. Our examination shows that regressions with adjustment for confounders and stratification fail to reveal the sociodemographic mechanisms that interact with occupational health problems, endangering the identification of occupational risks. Multilevel (notably MAIHDA) analyses, decision tree, cluster, and latent analyses are useful methods to consider when seeking to orientate prevention. Researchers should consider methods that adequately reveal the mechanisms connecting sociodemographic variables and occupational health outcomes., Competing Interests: The authors declare no conflict of interest.

This article aims to analyse the integration of sex and gender (s/g) by ergonomics students during their internship at the master's degree level, following training sessions on s/g issues in the workplace. This exploratory research used a descriptive mixed-methods design, encompassing evaluation of students' intention to use the content from the training ( n  = 13 students), and a multiple case study ( n  = 5 ergonomics interventions). The results show that while students found the training relevant, they only minimally integrated s/g in their interventions and when they did, it was primarily from an anthropometric and physiological perspective. In addition to discussing the training format limitations, the article discusses barriers to this integration: combining learning about s/g issues with learning about activity analysis is challenging; employers' and workers' organisations may be reluctant to approach s/g issues; and it is difficult for an ergonomist to integrate these issues when the employer's request does not specify it. Practitioner summary: This article aims to analyse the integration of s/g by ergonomics students during their internships. Findings show that they only minimally considered s/g. The discussion examines s/g training, organisational obstacles to inclusion of s/g during interventions, and how ergonomists can consider s/g in their practice.

Ergonomists intervene to improve work for all workers and adapt jobs to a range of worker characteristics. But their mandate rarely includes explicit attention to the distribution of worker demographics, to divisions among workers, or to discrimination on the basis of sex/gender or racialisation. A decades-long collaboration between ergonomists and the women's committees of three union confederations in Québec, Canada led to several instances where ergonomists had to confront situations involving sexism or racism, not foreseen during their training. This article will explore four problematic situations and suggest solutions, including paying more attention to teamwork, considering gender during ergonomics training, and developing a code of practice for ergonomics interventions. Practitioner summary: Workplace inequities related to sex/gender, racialisation and other sources of social inequity can affect job performance and workers' health. As such, do ergonomists need to consider them during an intervention? How? We analyse four situations encountered during interventions and suggest more attention to understanding workplace dynamics and promoting team function.

Background: The International Ergonomics Association (IEA) is an international federation of associations created in 1959, whose mission is to extend the scope of ergonomics research and intervention to all spheres of society in order to improve human well-being., Objective: This article presents an overview of the main research papers that were presented at the 21st Triennial IEA 2021 Conference., Method: A total of 23 talks, from nine countries, were presented over four sessions. These papers were summarized based on reading the abstracts and taking notes at the time of the oral presentation., Results: The themes of these sessions were: 1) Knowledge Transfer, Gender and Ergonomics 2) Approaching Ergonomic Interventions with a Sex/Gender Lens: Designing Training for Ergonomists 3) Ergonomic Studies of Atypical Work and Vulnerable Population Through a Sex/Gender Lens: Toward Better Understanding of Context and Risks, for Better Prevention and 4) Gender and Occupational Risks (Part 1: Exposure and Risk Perception; Part 2: Strategies to Manage Risk)., Conclusion: Ergonomists are beginning to understand that they have the qualifications and legitimacy to play a role in reducing workplace health inequities and helping to make workplaces inclusive and rich of all the workers' diversity. The four sessions of the Gender and Ergonomics TC have moved ergonomics practice a step closer to that goal.

Background: Women report more work-related pain and neck/shoulder musculoskeletal disorders than men. For the same absolute workload, due to lower strength, females generally work at a higher relative intensity, which could induce more fatigue. However, the arm's anthropometric load (AL) of men is higher. Therefore, simply lifting their arm could be more fatiguing. Sex as a variable is formed of many constructs, and analyses can become muddied by their differing responses to fatigue. No studies have considered AL, when comparing how fatigue affects men and women. The purpose was to determine if including the arm's AL in the statistical analysis would impact findings of sex-specific effects of shoulder fatigue on muscle EMG., Methods: Fifty-five (29m/26f) participants completed a repetitive pointing task (RPT) at shoulder height until they reported fatigue of 8+ on the BORG CR-10 scale. Muscle activities were measured using surface electrodes placed over the anterior deltoid (AD) and upper trapezius (UT) muscles. Muscle activity amplitude was quantified using root mean square (RMS). First- and last-minute data were used to assess change from no-fatigue (NF) to fatigue-terminal (FT) conditions. AL was calculated using sex-specific body parameter equations. General estimating equations (GEE) were used to determine the effects of sex and fatigue on RMS values, while including AL in the GEE., Results: There was no sex difference in time to reach fatigue. A significant main effect of sex on RMS was observed (χ 2 (1) = 4.17, p = 0.04) when including AL as a covariate. Females displayed a significantly higher percentage change in AD RMS from NF to FT, compared to males (p = 0.03), when AL was included in the GEE. No sex differences in UT were observed., Conclusions: This sex difference emerged when AL was included as a covariate, suggesting that sex-associated anthropometric differences may contribute to sex differences in the fatigue response. Differences in the impact of AL on AD compared to UT could be explained by differences in their respective mechanical roles or muscle fiber content. Anthropometrics may be useful to include as covariates in future research to separate individual anthropometric differences from sex differences.

At the 2018 IEA conference, the Gender and Work Technical Committee organized three symposia with over 20 presentations. Overall, these contributions positioned ergonomics as a theoretical and pragmatic approach developing innovative methods to integrate sex/gender analysis into the construction and evaluation of interventions. This special issue of Applied Ergonomics includes diverse approaches to the consideration of sex and gender in ergonomics, including methods in accident analysis, musculoskeletal disorders, work-family interactions, work schedule analysis, prevention programs and evaluation of interventions. The contents are summarized in this introduction., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2019 Elsevier Ltd.

The aim of this article is to examine the impacts of incorporating sex and gender (s/g) analysis in integrated knowledge translation (iKT) initiatives in the field of ergonomics and occupational health. The article presents findings based on a retrospective analysis of twelve intervention-research (IR) studies, including a thematic content analysis of in-depth interviews conducted with 15 researchers involved in these IRs. The findings offer an overview of various categories of impacts, such as changes in partners' views, in workplace settings and conditions, in practices and policies, and in economic outcomes. In these types of IR, health effects measurement is not the main objective, and direct health outcomes are difficult to assess. Explicitly talking about sex/gender led more often to system-level changes but less often to workplace-level changes, compared to interventions where sex/gender was not identified as a specific object of the intervention., (Crown Copyright © 2019.
