Work activity in food service: The significance of customer relations, tipping practices and gender for preventing musculoskeletal disorders

Positive Well-Being, Work-Related Rumination and Work Engagement among Chinese University Logistics Staff

Logistics personnel in Chinese universities are facing unbalanced costs and benefit from overloaded work with minimum wages, which impede school development and their well-being. However, the logistics staff population has been neglected in past investigations pertaining to psychological health conditions. The present study aimed to examine the positive well-being, work-related rumination, and work engagement of logistics staff, their correlations, and the factors affecting well-being in 282 Chinese university logistics staff via the Smith Well-being Questionnaire, the Work-Related Rumination Questionnaire, and the Utrecht Work Engagement Scale. The results indicated low levels of well-being and high levels of work-related rumination and work engagement among Chinese university logistics staff. The presence of positive attitudes towards life and work and high levels of work engagement predicts enhanced well-being, while the presence of negative characteristics and work-related rumination predicts decreased well-being. In situations where the working hours and work duties are challenging to change, universities can regularly schedule psychological counselling sessions for logistics staff to improve their well-being.

Comparing physical work exposures between men and women: findings from 65 281 workers in France

OBJECTIVES

Musculoskeletal disorders (MSDs) are a leading cause of disability and sick leave among workers. Although MSDs are associated with physical exposures, there are gender differences in the prevalence and related disability. This study aimed to compare self-reported physical work exposures by gender for people within the same occupational group.

METHODS

We used cross-sectional data from 65 281 asymptomatic workers aged 18-69 years from the CONSTANCES cohort study (France). We compared 27 physical exposures between men and women in the same occupational groups ('Profession et Categorie Sociale' group) using Mann-Whitney U tests.

RESULTS

Men and women performing the same job often reported different levels of exposure. 38 of 365 occupational groups had a gender difference in reported exposure for 10 or more of 27 physical exposures, with men reporting higher exposures in 79% of these jobs. Women reported higher exposures in nursing and other healthcare professions. The probability that a random man had an exposure value higher than a random woman varied widely, from 8% to 92%, and was highly dependent on occupational groups and the specific exposure.

CONCLUSIONS

Men and women working in the same jobs reported different physical exposures for some jobs and some exposures. Further research should further define and explore these reported differences to improve prevention and research.

How Can Quantitative Analysis Be Used to Improve Occupational Health without Reinforcing Social Inequalities? An Examination of Statistical Methods

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.

Should data on gender and ethnicity inform ergonomics interventions? Lessons from four case studies

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.

Do men and women have different musculoskeletal symptoms at the same musculoskeletal discomfort level?

Owing to biological and social factors, illness-related musculoskeletal symptoms tend to vary between men and women. However, in the past, conceptualised discomfort metrics were applied uniformly to both genders. This study aimed to develop a scale to measure musculoskeletal discomfort that compares the symptoms between men and women. The scale aimed to determine the gender-based response patterns related to symptoms. A total of 707 men and 1302 women reported their symptoms on a body map. Factor analysis and item response theory were used to differentiate the identified symptoms in the construction of a musculoskeletal discomfort scale. Differences in work exposure appeared to explain the symptom patterns between men and women. The scale had eight levels, and it was found that at the same level of discomfort, men and women reported symptoms in different body regions.Practitioner summary: On this discomfort scale, the response patterns of men and women were categorised into eight levels. Symptoms differed by gender at the same musculoskeletal discomfort level. This is in contrast to previous studies in which scales were devised without considering differences between the genders.Abbreviations: WMSDs: work-related musculoskeletal disorders; BMI: body mass index; FA: factor analysis; IRT: item response theory; KMO: Kaiser-Meyer-Olkin; BST: Bartlett's test of sphericity; F: factor loading; h2: communality; α: Cronbach's alpha; ωt: McDonald's omega; ai: parameters of discrimination of the items; bik: parameters of difficulty of response categories; θj: latent trait; RMSEA: root mean square error of approximation; CFI: comparative fit index; TLI: Tucker-Lewis index; odu: musculoskeletal discomfort units; RA: rarely; OF: often; AL: always.

'My whole body is at work': the silence of gendered body techniques in cork industry in an era of automation

Discourses about technological transformation tend to focus on technology, as if its introduction was neutral regarding local variabilities, and the men and women that make it effective. This paper focuses on the technical act. The body is where the technical acts are inscribed and it is through the body that they are exteriorised. The purpose of this paper is to analyse the operative modes associated with the technical acts, from a gender perspective, in the context of the technological transformation in cork industry. The analysis of the work activity performed by men (punching operators) and women (choosers) was supported by observations, collective interviews, and group sessions to validate the results. The findings show male- and female-specific body techniques; how the efficacy of the technical acts contributes to the debate about the limits of technology; and how body techniques and effects on health tend to remain in silence due to automation.Practitioner summary: The reconfiguration of the human-machine relationships hardly leaves room for the analysis of how the body techniques evolve. This paper shows how the efficacy of men and women body techniques contributes to the debate about the limits of technology, even if these uses of one's body entail health costs.

Sex and Gender Differences in Occupational Hazard Exposures: a Scoping Review of the Recent Literature

PURPOSE OF REVIEW

Comparative research on sex and/or gender differences in occupational hazard exposures is necessary for effective work injury and illness prevention strategies. This scoping review summarizes the peer-reviewed literature from 2009 to 2019 on exposure differences to occupational hazards between men and women, across occupations, and within the same occupation.

RECENT FINDINGS

Fifty-eight studies retrieved from eight databases met our inclusion criteria. Of these, 30 studies were found on physical hazards, 38 studies on psychological/psychosocial hazards, 5 studies on biological hazards, and 17 studies on chemical hazards. The majority of studies reported that men were exposed to noise, vibration, medical radiation, physically demanding work, solar radiation, falls, biomechanical risks, chemical hazards, and blood contamination; while women were exposed to wet work, bullying and discrimination, work stress, and biological agents. Within the same occupations, men were more likely to be exposed to physical hazards, with the exception of women in health care occupations and exposure to prolonged standing. Women compared to men in the same occupations were more likely to experience harassment, while men compared to women in the same occupations reported higher work stress. Men reported more exposure to hazardous chemicals in the same occupations as women. The review suggests that men and women have different exposures to occupational hazards and that these differences are not solely due to a gendered distribution of the labor force by occupation. Findings may inform prevention efforts seeking to reduce gender inequalities in occupational health. Future research is needed to explain the reasons for sex/gender inequality differences in exposures within the same occupation.

The health of restaurant work: A historical and social context to the occupational health of food service

The United States currently has over one million restaurants, making food service one of the largest workforces and industry sectors in the nation's economy. Historically, concern for the health of early restaurant workers was tied largely to the hygiene of the food and thus the wellbeing of the customer rather than the individuals preparing the food. The landscape of occupational illness and injury that resulted is fraught with some of the starkest health disparities in wages, discrimination, benefits, injuries, and illness seen among US laborers. These disparities have consistently been associated with social class and economic position. Conditions identified during the early years of restaurant work, before the introduction of occupational safety and health protections, persist today largely due to tipped wages, dependence on customer discretion, and the management structure. Research and intervention efforts to control occupational health hazards should be directed toward the socioeconomic and structural roots of health problems among food service workers in the United States. Such efforts have important implications for enhancing worker protections, improving wages, and restructuring working conditions for restaurant and food service workers. They also suggest opportunities for occupational health practitioners and researchers to contribute to system-level change analysis to address centuries-old occupational health challenges still facing one of the largest sectors of workers in the country.

Impacts of considering sex and gender during intervention studies in occupational health: Researchers' perspectives

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.

Age and sex related differences in shoulder abduction fatigue

BACKGROUND

Injury prevalence data commonly indicate trends of higher rates of work-related musculoskeletal disorders in older workers over their younger counterparts, and for females more than males. The purpose of this study was to investigate age and sex-related differences in manifestations of shoulder muscle fatigue in a cohort of young and older working age males and females, in a single experiment design allowing for direct comparison of the fatigue effects between the target groups.

METHODS

We report upper trapezius muscle fibre Conduction Velocity (CV) as an indicative measure of muscle fatigability, and isometric endurance time, at three levels of shoulder abduction lifting force set relative to participants' maximal strength.

RESULTS

Upper trapezius conduction velocity was significantly different between the young and old groups (p = 0.002) as well as between males and females (p = 0.016). Shoulder abduction endurance time was affected by age (P = 0.024) but not sex (p = 0.170).

CONCLUSIONS

The study identified age-related improvement in muscle fatigue resistance and increased resistance for females over males, contrary to injury prevalence trends. The muscle fatigue effects are most likely explained by muscle fibre type composition. Experimental fatigue treatments of the upper trapezius were tested at exposures relative to the participants' strength. Absolute strength is higher when young and is generally higher for males. The findings of this study point towards age and sex-related differences in strength rather than in muscle fatigue resistance as a primary cause for the differences in the injury trends.

Taking Account of Gender Differences When Designing Interventions in Occupational Health? Lessons from a Study of the "Healthy Enterprise" Standard in Québec: Les différences de genre sont-elles prises en compte lors de la conception des interventions de prévention en santé au travail? Résultats d une étude sur la norme "Entreprises en Santé" dans les entreprises au Québec

The literature shows substantial differences in occupational exposures between men and women, both between and within occupations, but remains very sparse on whether interventions are tailored to gender differences in the workplace. Our objective was to determine whether gender differences are taken into account when designing prevention interventions. This study is part of a project on the evaluation of interventions implemented in the framework of the "Healthy Enterprise" standard in Quebec organizations. Three sets of quantitative and qualitative data were collected in seven organizations and triangulated. Our results show that in the process of elaborating and implementing activities, the main objectives were to reach a maximum number of workers and meet the needs identified in a health and risk diagnosis. Activities were not tailored to the needs of specific subgroups of employees, such as gender or age. Not distinguishing men's and women's situations in this diagnosis may play a role in intervention design. Résumé La littérature montre des différences d'exposition au travail importantes entre les hommes et les femmes, y compris à catégories d'emploi identiques. Les études sur l'adaptation des interventions de prévention aux différences de genre dans les milieux de travail sont quasiment inexistantes dans la littérature. Notre objectif était de déterminer dans quelle mesure les différences de genre sont prises en compte lors de la conception des interventions de prévention. Cette étude fait partie d'un projet d'évaluation des interventions mises en œuvre dans le cadre de la norme «Entreprises en santéé au Québec. Trois séries de données quantitatives et qualitatives ont été collectées auprès de sept organisations et analysées par triangulation. Nos résultats montrent que lors du processus d'élaboration des activités, les principaux objectifs étaient d'atteindre un nombre maximal de travailleurs et de remplir les besoins identifiés dans le diagnostic des risques et de la santé des travailleurs. Le fait que la situation des hommes et des femmes n'ait pas été analysée séparément dans le diagnostic peut avoir joué un râle dans ce résultat. Les activités de prévention n'ont pas été conçues en tenant compte de sous-groupes de travailleurs en fonction du genre ou de l'âge.
