Job satisfaction and job security as moderators in the relationships among job demands, musculoskeletal symptoms, and work performance.

PURPOSE: This study examined whether job satisfaction and job security moderate the path from physical demands and job strain to impaired work performance via musculoskeletal symptoms in the upper extremities (MSUE). Moderation effects on five paths were examined: (1) from job strain to MSUE; (2) from job strain to work performance; (3) from physical demands to MSUE; (4) from physical demands to work performance; (5) from MSUE to work performance. METHODS: This was a cross-sectional study of 669 full-time workers from 9 manufacturing and 3 healthcare facilities. Data were collected via health interviews, on-site physical exposure assessments, and computation of the Strain Index by ergonomists, and self-administered questionnaires on psychosocial factors. Structural equation modeling and zero-inflated negative binomial regression analysis were performed to examine the moderation effect on each path. RESULTS: Job satisfaction moderated the relationship between MSUE and impaired work performance (B = - 0.09, 95% CI: - 0.15, - 0.04) and job security moderated the relationship between physical demands and MSUE (B = - 0.64, 95% CI: - 1.17, - 0.11). Interaction between job satisfaction and MSUE was significant on both the occurrence (OR: 0.92, 95% CI: 0.87, 0.97) and the degrees of impaired work performance (mean ratio: 0.99, 95% CI: 0.97, 0.99), while the interaction between job security and physical demands was significant only on the degrees of MSUE (mean ratio: 0.94, 95% CI: 0.89, 0.99). CONCLUSION: Job satisfaction and job security can, respectively, mitigate the adverse impacts of working with MSUE and physical demands on work performance. Workplace interventions to improve workers' job satisfaction and job security can contribute to their musculoskeletal health and work performance.

Underreporting of work-related low back pain among registered nurses: A mixed method study.

BACKGROUND: Identifying and addressing work-related health problems early is crucial, but workers often perceive barriers in reporting these to management. This study aimed to investigate the factors associated with nurses' reporting of work-related low back pain to their managers and explored the reasons why nurses with patient handling injuries did not report them. METHODS: This study is a concurrent mixed-method analysis of data from two statewide cross-sectional surveys of California registered nurses conducted in 2013 and 2016. The reporting of work-related low back pain to management (n = 288) was examined for associations with individual, occupational, and organizational factors. For qualitative analysis, the reasons for not reporting patient handling injuries were explored using open-ended responses (n = 42). RESULTS: Reporting was associated with BIPOC (Black, Indigenous, and People of Color) men (adjusted odds ratio [AOR]: 1.31, 95% confidence interval [CI]: 1.07-1.59) compared to non-Hispanic White women; being a non-US educated nurse (AOR: 0.90, 95% CI: 0.80-1.01); experiencing greater low back pain (AOR: 1.07, 95% CI: 1.02-1.12); missing work (AOR: 1.38, 95% CI: 1.21-2.62); perceiving high physical workload (AOR: 0.89, 95% CI: 0.81-0.98); perceiving high people-oriented culture (AOR: 1.14, 95% CI: 1.04-1.25); and perceiving high ergonomic practices (AOR: 0.89, 95% CI: 0.81-0.98). Identified themes on the reasons for not reporting injuries included organizational-culture attitudes toward work-related injuries and injury characteristics of musculoskeletal disorders. CONCLUSIONS: The findings indicate a need for management to remove structural barriers and improve organizational practices, and for a culture that promotes trust and open communication between workers and management.

Interaction between physical demands and job strain on musculoskeletal symptoms and work performance.

This study investigated the interaction between physical demands and job strain on musculoskeletal symptoms in upper extremities (MSUE) and work performance. Two years of prospective data were analysed from 713 full-time workers from twelve manufacturing and healthcare facilities in Washington in the United States. Physical exposure was measured by the Strain Index and Threshold Limit Value for hand activity, giving rise to safe, action, and hazardous physical demand groups. Job strain was calculated as the ratio of psychological job demands to job control. Multilevel modelling analysis showed that job strain affected MSUE and limited work performance less in the high physical demand group than the safe group because the protective effect of job control was smaller in these groups. Findings may suggest that high physical demand jobs are structured such that workers have low job control or high physical demand groups experience job strain not adequately captured by psychosocial variables.Practitioner Summary: The effects of job strain and job control on musculoskeletal symptoms in upper extremities and work performance were smaller among workers with higher physical demands. This could imply that high physical demand jobs limit job control or psychosocial variables may not adequately capture job strain among high physical demand groups.

Differences in employment, job characteristics, and work-related perceptions by sociodemographic factors among registered nurses of diverse race/ethnicity.

BACKGROUND: Available research on registered nurses (RNs) indicates that RNs with diverse race/ethnicity are more likely to work in disadvantaged workplaces. PURPOSE: To examine differences in employment, job characteristics and perceptions about work among RNs by sociodemographic characteristics. METHODS: We analyzed data from statewide random samples of California RNs (N=895). FINDINGS: Increased age was associated with increased likelihoods of working part-time, day-shift, and in non-hospital settings and having managerial positions. Asian and Black nurses were more likely to work in urban areas than White nurses. The levels of job demand, job control, job satisfaction, perceived organizational culture, and safety climate were significantly different by sociodemographic characteristics. Greater intention to leave the job was associated with younger age and working in non-hospital settings. DISCUSSION: The findings suggest that differences exist in nurses' employment, job characteristics, and perceptions about their work and work environment by sociodemographic characteristics among RNs of diverse race/ethnicity.

Effects of perceived risk of COVID-19 on fear among visiting workers: Mediating role of perceived stress.

With the creation of a social distancing policy due to coronavirus disease 2019 (COVID-19), home visit workers are under mental stress as they are treated as the source of infection for COVID-19. Since door-to-door rental equipment examiners and gas inspectors must perform their duties even in the COVID-19 situation, they are being discriminated against so severely. The purpose of study was to examine the mediating role of perceived stress on the relationship between risk perception and fear. Data was collected data through labor unions among 275 home visiting workers who examine rental home appliance equipment or inspecting gas. On-line survey was conducted to assess COVID-19 risk perception, fear, perceived stress, and demographic characteristics. The data was analyzed using PROCESS Macro (Model 4). The results of the study showed that stress plays an important role in increasing COVID-19 fears when COVID-19 risk perception increases. Meanwhile, it was found that COVID-19 fear decreased when the level of perceived stress decreased. To reduce the impact of COVID-19 risk perception on COVID-19 fears, appropriate educational programs to reduce stress should be developed for home visit workers. Policymakers need to develop online or mobile Infectious disease education programs for COVID-19 risk at work and establish policies to apply legal education.

Fatigue, Toll-Like Receptor 4, and Pro-Inflammatory Cytokines in Adults With Subarachnoid Hemorrhage: A 6-Month Longitudinal Study.

BACKGROUND: Fatigue is prevalent in subarachnoid hemorrhage (SAH) survivors. Biological mechanisms underlying fatigue post-SAH are not clear. Inflammation may contribute to the development of fatigue. This study aimed to examine the associations between inflammatory markers and fatigue during the first 6 months post-SAH. Specific biomarkers examined included both early and concurrent expression of Toll-Like Receptor 4 (TLR4) messenger RNA (mRNA) and plasma concentrations of pro-inflammatory cytokines, Tumor Necrosis Factor-alpha (TNF-α), Interleukin (IL)1ß, and IL6. METHODS: We conducted a 6-month longitudinal study with a convenience sample of 43 SAH survivors. We collected blood samples on days 2, 3, and 7 and 2, 3, and 6 months post-SAH to assess biomarkers. Fatigue was assessed by the PROMIS Fatigue Scale at 2, 3, and 6 months. Linear mixed models were used to test the associations between early (days 2, 3, and 7) and concurrent (2, 3, and 6 months) TLR4 mRNA expression (TagMan gene expression assays) and TNF-α, IL1ß, and IL6 plasma concentrations (multiplex assays) and concurrent fatigue. RESULTS: 28% of SAH survivors experienced fatigue during the first 6 months post-SAH. Fatigue levels in SAH survivors were higher than those of the U.S. population and consistent during the 6 months. Experience of fatigue during the 6 months post-SAH was associated with higher IL1ß plasma concentrations on day 7 and IL1ß, IL6, and TNF-α plasma concentrations during the 6 months post-SAH. CONCLUSION: Inflammation appears to underlie the development of fatigue in SAH survivors.

Sleep Disturbance and Self-management in Adults With Subarachnoid Hemorrhage: A Qualitative Study.

Subarachnoid hemorrhage (SAH) survivors often experience sleep disturbances. Little is known about sleep-management practices used to improve their sleep. The purpose of this qualitative study was to explore interest in and engagement with self-management practices to promote sleep health in SAH survivors. We conducted a cross-sectional qualitative study using semi-structured interviews with a convenience sample of 30 SAH survivors recruited from a university hospital. We conducted content analysis of interview transcripts. Three themes and 15 subcategories were identified: (1) sleep disturbances (difficulties falling asleep, wake after sleep onset, daytime sleepiness, too much or insufficient sleep, and poor sleep quality); (2) sleep-management practices (exercise, regular sleep schedule, relaxation, keeping busy and staying active, changing beverage intake, taking supplements, taking medications, recharging energy, and barriers to sleep management); and (3) consulting with healthcare providers (discussing sleep problems with healthcare providers). Self-management strategies focusing on health-promoting behaviors may improve SAH survivors' sleep health.

Identifying an Optimal Cut-Off Point for Musculoskeletal Pain in the Upper Extremities to Prevent Lowered Work Performance.

OBJECTIVE: This study identified when musculoskeletal pain (MSP) in the upper extremities indicates lowered work performance to gauge when secondary prevention of musculoskeletal disorders is needed. METHODS: Seven hundred thirty-three subjects from 12 manufacturing or healthcare facilities in Washington state participated. Work performance was measured by the Disabilities of the Arm, Shoulder and Hand work module (DASH-Work). Each DASH-Work score was compared to the mean among U.S. workers to determine if workers had lowered work performance. ROC curve analysis was conducted to find the cut-off in a composite MSP index (summing MSP intensities in shoulders, elbows/forearms, and hands/wrists; range 0 to 24) to detect lowered work performance. RESULTS: The MSP index score of 2 achieved the best balance between sensitivity (0.79) and specificity (0.69) in detecting lowered work performance. CONCLUSIONS: To prevent reduced work performance, moderate or multisite pain may require proper management.
