The physical activity paradox: a longitudinal study of the implications for burnout

Purpose This study investigates the independent and interactive associations of physical job demands and three types of off-job physical activity (during transportation, household, and recreation) with burnout. We use a recently proposed new conceptualization and assessment of burnout including core and secondary burnout symptoms. We predicted that physical job demands would be positively and the three types of off-job physical activity would be negatively related to burnout. Further, we hypothesized that the negative relations between the three types of off-job physical activity and burnout would be stronger for employees with low (vs. high) physical job demands. Methods To test our hypotheses, we conducted a two-wave survey study among a heterogeneous sample of full-time workers (N = 355), using a longitudinal design with a half-year time lag. We tested cross-sectional, prospective and longitudinal relations. Results Hierarchical regression analyses partly confirmed our predictions. Cross-sectionally and prospectively, it was shown that physical job demands were positively related to burnout symptoms. In addition, off-job physical activity was negatively related to primary and secondary burnout symptoms among employees with low physical job demands and positively related to burnout symptoms among employees with high physical job demands. However, these relationships disappeared when investigated longitudinally. Conclusion Together, these findings suggest that not all off-job physical activities can prevent burnout, and that potential positive effects of physical activity during off-job time may depend on employees’ physical activity level at work.

Suddenly Working From Home!

The Corona crisis and the lockdown in the spring of 2020 had various effects on working life in Europe. In this three-wave study, we assessed the trajectories of job demands and resources of 302 employees 2 weeks before the lockdown, over 1 week after lockdown start, and 6 weeks following the beginning of the lockdown. We applied a pre-post follow-up design with 129 employees who switched to telecommuting and a control group of 173 employees who remained in their on-site workplace. Results from the repeated-measures MANCOVA indicate that, despite various general changes to job characteristics because of the Corona crisis, telecommuting changes contributed to significant changes only in communication opportunities and – before Bonferroni correction – in physical job demands. These results may imply that the most visible massive switch to telecommuting of many employees during the first phase of the Corona crisis is only one explanatory factor for general changes to job characteristics.

Promoting Opioid Awareness Through a Union-Based Peer Training Model

Work factors, including physical job demands, appear to be risk factors for opioid overdoses. We collaborated with unions representing workers in high-risk occupations and offered resources to develop tailored educational interventions for their members. An ironworkers’ local, a statewide nurses’ union, and a Teamsters local union participated, at levels higher than we had anticipated. The three unions trained 285 workers, including apprentices, stewards, and those nearing retirement. Short surveys assessed pre- and post-training knowledge, attitudes, confidence in helping others, and related domains. Seventy percent of respondents reported heavy or very heavy physical demands at work, and one-half had experienced work-related pain. After training, participants reported more knowledge about opioids, less concern about stigma related to help-seeking, and more ability to provide help to a co-worker struggling with opioids. Peers with recovery experience provided a unique contribution to training. Tailored job-specific and peer-delivered educational interventions may be able to reduce the potential impact of opioids on working people.

Upper extremity strength: Normative reference data among uninjured employees

BACKGROUND: Extremity strength testing is used to determine the ability of industrial employees to perform a physically demanding occupation safely, evaluate post-injury impairment, and monitor return to function after injury. There is an unmet clinical need for a robust and granular source of normative reference values to serve as a resource for baseline data on upper extremity isometric strength. OBJECTIVE: Develop normative reference data for upper extremity strength among industrial employees and investigate associations between strength and physical job demands. METHODS: Upper extremity strength data from 107,102 industrial employees were collected post-hire. In this study, isometric tests for pinch; hand grip; wrist pronation and supination; and flexion of the wrist, elbow, and shoulder strength were retrospectively analyzed in relationship to sex, age, and job level. Associations between strength scores and five levels of work, defined the United States Department of Labor’s Dictionary of Occupational Titles by level of physical difficulty (1–5), were determined. RESULTS: Higher strength scores were positively associated with more physically demanding job levels (P < 0.001), and there was a progressive increase in strength scores with increased physical job demands for both sexes (P = 0.0002). All strength scores differed significantly by decade of age (P < 0.001). All scores except for pinch strength demonstrated a moderate or high positive correlation with job level (r≥0.50). CONCLUSIONS: The normative reference upper extremity strength data collected in this study for industrial employees may be useful for evaluating rehabilitation and recovery following injury or illness. In order to utilize normalized strength data as a post-injury reference, it is important to consider job level in addition to age and sex, as these variables are highly correlated with baseline upper extremity strength.

Distributions of Job Physical Exposure Data in a Pooled Study of Low Back Pain Prospective Cohorts

Low back pain (LBP) is a common health problem and a major cause of lost productivity in workplaces. Lifting and lowering (LL) activities have traditionally been regarded as risk factor for LBP. In the literature, very little data have been reported describing industrial workers’ exposures to measured job physical demands using comprehensive and quantitative method, such as the revised NIOSH lifting equation (RNLE). This study pooled physical exposure data for the RNLE commonly collected in three independent LBP prospective studies. In total, over one million subtasks (i.e., lifting/lowering activities) were included in this pooled study. Examination of the pooled dataset revealed an increased data distribution of the physical job demands quantified by the RNLE. Research using the pooled dataset will improve the overall statistical power and help address the weaknesses identified in previous studies.

Changes in autonomy, job demands and working hours after diagnosis of chronic disease: a comparison of employed and self-employed older persons using the English Longitudinal Study of Ageing (ELSA)

BackgroundModifications in working conditions can accommodate changing needs of chronically ill persons. The self-employed may have more possibilities than employees to modify their working conditions. We investigate how working conditions change following diagnosis of chronic disease for employed and self-employed older persons.MethodsWe used waves 2–7 from the English Longitudinal Study of Ageing (ELSA). We included 1389 participants aged 50–60 years who reported no chronic disease at baseline. Using fixed-effects linear regression analysis, we investigated how autonomy, physical and psychosocial job demands and working hours changed following diagnosis of chronic disease.ResultsFor employees, on diagnosis of chronic disease autonomy marginally decreased (−0.10, 95% CI −0.20 to 0.00) and physical job demands significantly increased (0.13, 95% CI 0.01 to 0.25), whereas for the self-employed autonomy did not significantly change and physical job demands decreased on diagnosis of chronic disease (−0.36, 95% CI −0.64 to –0.07), compared with prediagnosis levels. Psychosocial job demands did not change on diagnosis of chronic disease for employees or the self-employed. Working hours did not change for employees, but dropped for self-employed (although non-significantly) by about 2.8 hours on diagnosis of chronic disease (−2.78, 95% CI −6.03 to 0.48).ConclusionImprovements in working conditions after diagnosis of chronic disease were restricted to the self-employed. This could suggest that workplace adjustments are necessary after diagnosis of chronic disease, but that the self-employed are more likely to realise these. Policy seeking to extend working life should consider work(place) adjustments for chronically ill workers as a means to prevent early exit from work.

Factors Affecting Prolonged Working Life for the Older Workforce: the Swedish Case

The aim of this paper is to uncover some of the mechanisms that could make the older workforce willing and able to stay employed. Our focus is on work-related factors that predict the probability of staying in employment despite entitlement to old-age pension. The analyses are based on data from the first and second waves of the Panel Survey of Ageing and the Elderly (PSAE). The focus is on employed persons aged 52–59 years in 2002/2003 and the probability that they were still employed in 2010/2011.The analysis focuses on the work situation for the respondents in 2002–2003. Our analysis shows that physical job demands (negatively) and job satisfaction (positively) have an effect on the probability of staying. However, a counteracting force seems to be a norm to quit related to aging, emphasized by the institutionalized pension system, and the values and preferences connected to life as a pensioner.
