High leisure‐time physical activity reduces the risk of long‐term sickness absence

Leisure-Time Physical Activity to Reduce Risk of Long-Term Sickness Absence Across Diverse Subgroups in the Working Population-A Prospective Cohort Study of 68,000 Participants

BACKGROUND

There is a dearth of knowledge regarding the relationship between engaging in moderate and vigorous physical activity and long-term sickness absence (LTSA), particularly among various population subgroups such as individuals of different ages or body mass indices. We aimed to evaluate the prospective associations of moderate and vigorous leisure-time physical activity with the risk of LTSA in the general working population.

METHODS

A prospective cohort study with a 2-year register follow-up was conducted, where 68,222 representative workers from Denmark completed a questionnaire about work environment, lifestyle, and health. Data on LTSA (≥6 consecutive weeks of sickness absence) were obtained from the Danish Register for Evaluation of Marginalization. We used Cox regression for the statistical analysis, adjusting for relevant confounding factors. We also performed age- and BMI-stratified analyses.

RESULTS

In the fully adjusted model, 2 to 4 hours per week of moderate activity (hazard ratios [HR] = 0.87; 95% CI, 0.77 to 0.99) and ≥2 hours per week of vigorous activity reduced LTSA risk compared with no physical activity. However, 2 to 4 hours per week of vigorous activity (HR = 0.84; 95% CI, 0.76 to 0.91) provided the greatest risk reduction. In the total sample, the complete absence of vigorous activity was associated with increased risk of LTSA (HR = 1.13; 95% CI, 1.05 to 1.22). In stratified analyses, the results were consistent for workers <50 years (HR = 1.14; 95% CI, 1.03 to 1.26), ≥50 years (HR = 1.13; 95% CI, 1.02 to 1.26), and those with a BMI ≥ 25 (HR = 1.16; 95% CI, 1.06 to 1.28). The complete absence of moderate activity was not associated with LTSA.

CONCLUSION

Vigorous leisure-time physical activity appears to be more important than moderate activity to prevent LTSA.

Associations Between Active Commuting and Sickness Absence in Finnish Public Sector Cohort of 28 485 Employees

Active commuting can be beneficial for health. We examined whether active commuting by walking or cycling was associated with a lower risk of sickness absence in a Finnish public sector cohort of 28 485 employees. We used negative binomial regression to test associations of weekly active commuting in kilometers (no, low, moderate, and high dose) with all-cause sickness absence. Sickness absence data from employers registers comprised the number of (1) sickness absence days, (2) short (1-9 days) and (3) long (≥ 10 days) sickness absence episodes during 12- and 24-month follow-ups. The models were adjusted for sociodemographic factors, lifestyle risk factors, and previous sickness absence. To demonstrate absolute risk, we calculated sex- and age-adjusted incidence for sickness absence per 100 person years for each active commuting exposure group. The associations of cycling and walking were additionally studied in separate analyses. Compared to passive commuters (no active commuting), high dose of active commuting (mean of 61 km/week) was associated with an 8%-12% lower relative risk of sickness absence days and an 18% lower relative risk of long episodes. The absolute rate of sickness absence per 100 person-years was up to 452 days and 10 long episodes lower in the high-dose active commuters group. In the further analyses separating cyclists and walkers, similar reduced risks were observed only among high-dose cyclists. Our findings suggest that regular active commuting by bicycle has potential for reducing sickness absence by reducing the risk of long sickness absence episodes.

Sex-Specific Associations Between Lifestyle Factors and Sick Leave in the Serbian Working Population: Findings from the National Health Survey

Background/Objectives: Sick leave is influenced by various modifiable lifestyle factors and sex differences. This study investigates the associations between body mass index, fruit and vegetable consumption, physical activity, smoking, and alcohol consumption and sick leave among Serbia's working population, with emphasis on sex differences. Methods: Data from the 2019 National Health Survey of Serbia were analyzed, involving a sample of 4652 individuals. Chi-square tests and logistic regression models assessed the relationships between lifestyle factors and sick leave. Results: Among the participants, 15.8% reported sick leave in the past 12 months, with higher rates among women in both short-term (13.9% vs. 10.6%) and long-term (3.4% vs. 2.2%) sick leave. This study identifies obesity (OR = 2.6), poor dietary habits (fruit OR = 2.1; vegetables OR = 2.8), smoking (OR = 1.9), and risky alcohol consumption (OR = 4.1) as key predictors of sick leave in men, while smoking (OR = 1.8) and risky alcohol consumption (OR = 3.1) are major predictors in women. The inconsistent association between diet, physical activity, and sick leave may be attributed to differences in reporting accuracy, differing definitions of healthy intake, or the influence of unmeasured lifestyle factors. Conclusions: Smoking and risky alcohol consumption increase the odds of sick leave for both sexes. Interventions targeting smoking cessation and mitigating risky alcohol consumption could significantly decrease sick leave rates. While fruit and vegetable consumption, along with physical activity, showed inconsistent effects in both sexes, further studies are warranted to elucidate their roles.

Perceived health outcomes of recreation and happiness: exploring the mediating role of resilience

Introduction

Previous research has shown that leisure activities can positively influence perceived health outcomes by increasing individuals' levels of physical activity. Yet, little has been discovered about the mechanisms that are driving this association. This study was conducted with the aim of examining the relationship between perceived health outcomes of recreation and happiness as well as the mediating effect of resilience.

Methods

The study comprised a total of 451 adult individuals residing in seven different geographical regions of Turkey, who were included using a convenience sampling method, and the data were collected between March and June 2023. Respondents completed assessments utilizing the Perceived Health Outcomes of Recreation, Brief Resilience Scale, and The Oxford Happiness Questionnaire-Short Form. Data analysis was executed employing the PROCESS macro for SPSS.

Results

The study's findings revealed that perceived health outcomes of recreation had a positive effect on both happiness (β = 0.146, [95% CI: 0.106, 0.186]) and resilience (β = 0.156, [95% CI: 0.107, 0.205]). Resilience had a positive effect on happiness (β = 0.435, [95% CI: 0.362, 0.507]). Furthermore, the relationship between perceived health outcomes of recreation and happiness was partially mediated by resilience (β = 0.068, [95% CI: 0.042, 0.096]).

Conclusion

As a result, participating in leisure activities has been found to have a positive impact on perceived health outcomes, which in turn positively affects both happiness and resilience. Additionally, psychological resilience can be said to partially mediate the relationship between perceived health outcomes of recreation and happiness.

Does the distribution of musculoskeletal pain shape the fate of long-term sick leave? A prospective cohort study with register follow-up

ABSTRACT

Although multisite pain can markedly reduce work ability, the relevance of the bodily pain distribution as a predictor of long-term sick leave is still unknown. This study aimed to investigate the association between musculoskeletal pain distributions and long-term sick leave in the general working population of Denmark and included 66,177 currently employed wage earners without long-term sick leave during the prior 52 weeks. Participants reported whether they had pain in the lower extremity (hips/knees), upper extremity (neck/shoulders), or the low back. The analysis controlled for age, sex, year of survey reply, educational level, occupational group, psychosocial work factors, body max index, smoking, leisure-time physical activity, and mental health confounders. The results demonstrated that the risk of long-term sick leave increased with the number of pain sites. Compared with no pain, localized pain in any body region increased the risk/hazard by 25% to 29% (HR [95% CI]: 1.29 [1.07-1.54] for pain only in the low back), whereas pain in 2 regions increased the risk by 39% to 44% (HR [95% CI]: 1.41 [1.18-1.69] for pain in the low back + hips/knees). Workers reporting pain in all 3 regions experienced a 72% increased risk (HR [95% CI]: 1.72 [1.55-1.91]). Thus, the number of pain regions seems to matter more than the exact pain location. The spatial extension of musculoskeletal pain in workers functions as a gradient system, where pain spread throughout the body is an independent indicator of the high risk of long-term sick leave.

The effect of exercise therapy as a tool for preventing and treating musculoskeletal disorders among school-aged children: a randomised controlled trial

BACKGROUND

Children spend a lot of time in school, and there are many ergonomic hazards and postural malalignments that put children at greater risk of developing musculoskeletal disorders (MSDs). This study aimed to investigate the effect of exercise therapy on preventing and treating musculoskeletal disorders among school-aged children.

METHOD

This randomised controlled trial included 212 (121 boys and 91 girls) school-aged children aged 13-15 years assigned to treatment (n = 106) and prevention (n = 106) groups, where the treatment group contained individuals with MSDs and prevention group contained individuals without MSDs. In each group, half of the individuals received exercise therapy (50 min per session, four times per week, for an 8-week), and others continued their daily lives. MSDs and physical activity were assessed by the Teen Nordic Musculoskeletal Screening Questionnaire and the International Physical Activity Questionnaire-Short Form, respectively, at baseline and after the experimental protocol.

RESULTS

There was a statistically significant reduction in the frequency of MSDs in the treatment group and occurring MSDs in the prevention group (P ≤ .05). Also, there was significant improvement in all variables of walking, moderate physical activity, vigorous physical activity, and total in intervention groups spatially in students who received exercise therapy (P ≤ .05).

CONCLUSIONS

This study demonstrated the effectiveness of exercise therapy in reducing and preventing MSDs and improving physical activity levels among school-aged children aged 13-15 years.

Musculoskeletal pain intensity and risk of long-term sickness absence in the general working population: A prospective cohort study with register follow-up

Determining predictors of sickness absence could allow for better screening, guidance, and development of preventive efforts aimed at those in increased risk. This study aimed to determine the prospective association between musculoskeletal pain intensity and risk of incident register-based long-term sickness absence in the general working population, as well as to determine the population attributable fraction. Drawing on data from a nation-wide questionnaire survey, this prospective cohort study followed a representative sample of the Danish general working population without recent long-term sickness absence (≥6 consecutive weeks) (n = 69,273) for long-term sickness absence up to two years (mean follow-up: 93 weeks) in a national register. The predictor was musculoskeletal pain intensity in the neck/shoulder and low-back during the preceding three months rated on an 11-point numerical rating scale from 0 to 10. The weighted incidence of long-term sickness-absence was 8.9% during two-year follow-up (n = 6165). We observed a clear dose-response association between musculoskeletal pain intensity of the neck/shoulder or low-back and the risk of incident long-term sickness absence, with a lower threshold of increased risk of 4 and 3 (scale 0-10) for neck/shoulder (HR (95% CI): 1.25 (1.09-1.42)) and low-back pain (HR (95% CI): 1.13 (1.00-1.29)), respectively. Prevention of pain intensities at or above 4 out of 10 could potentially prevent 17% (population attributable fraction, PAF (95% CI): 16.8 (13.6-20.1)) of the total long-term sickness absence in the general working population. Large-scale interventions to prevent and manage musculoskeletal pain need to be documented and implemented.

The moderating role of physical activity on the relationship between work intensity and depressive symptoms among the employees

Our aim was to examine the associations between work intensity and depressive symptoms among the working population, as well as to identify the impact of physical activity (PA) on these relationships. Spearman correlation analysis was conducted to analyze the correlations among work intensity, PA, and depressive symptoms. Working hours and working days were positively correlated with depressive symptoms (r = 0.108, 0.063; all p values were <0.001). Regular PA, exercise time, exercise frequency, and exercise years were negatively correlated with depressive symptoms (r = -0.121, -0.124, -0.152, -0.149; all p values were <0.001) and working days (r = -0.066, -0.050, -0.069, -0.044; all p values were <0.001), working hours (r = -0.113. -0.106, -0.161, -0.123; all p values were <0.001). Working days was positively correlated with working hours (r = 0.512, p < 0.001). Different levels of PA alleviated the effect of working hours or working days on depressive symptoms. Working hours seemed to be more correlated with depressive symptoms than working days. The results suggest that PA at any level could buffer against the effects of work intensity and might prove a helpful strategy for improving mental health issues among employees.

Effectiveness of eHealth Interventions Targeting Employee Health Behaviors: Systematic Review

BACKGROUND

The number of people with noncommunicable diseases is increasing. Noncommunicable diseases are the major cause of disability and premature mortality worldwide, associated with negative workplace outcomes such as sickness absence and reduced work productivity. There is a need to identify scalable interventions and their active components to relieve disease and treatment burden and facilitate work participation. eHealth interventions have shown potential in clinical and general populations to increase well-being and physical activity and could be well suited for workplace settings.

OBJECTIVE

We aimed to provide an overview of the effectiveness of eHealth interventions at the workplace targeting employee health behaviors and map behavior change techniques (BCTs) used in these interventions.

METHODS

A systematic literature search was performed in PubMed, Embase, PsycINFO, Cochrane CENTRAL, and CINAHL in September 2020 and updated in September 2021. Extracted data included participant characteristics, setting, eHealth intervention type, mode of delivery, reported outcomes, effect sizes, and attrition rates. Quality and risk of bias of the included studies were assessed using the Cochrane Collaboration risk-of-bias 2 tool. BCTs were mapped in accordance with the BCT Taxonomy v1. The review was reported according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) checklist.

RESULTS

In total, 17 randomized controlled trials met the inclusion criteria. The measured outcomes, treatment and follow-up periods, content of eHealth interventions, and workplace contexts had high heterogeneity. Of the 17 studies, 4 (24%) reported unequivocally significant findings for all primary outcomes, with effect sizes ranging from small to large. Furthermore, 53% (9/17) of the studies reported mixed results, and 24% (4/17) reported nonsignificant results. The most frequently targeted behavior was physical activity (15/17, 88% of the studies); the least frequently targeted behavior was smoking (2/17, 12% of the studies). Attrition varied greatly across the studies (0%-37%). Risk of bias was high in 65% (11/17) of the studies, with some concerns in the remaining 35% (6/17). Interventions used various BCTs, and the most frequently used were feedback and monitoring (14/17, 82%), goals and planning (10/17, 59%), antecedents (10/17, 59%), and social support (7/17, 41%).

CONCLUSIONS

This review suggests that, although eHealth interventions may have potential, there are still unanswered questions regarding their effectiveness and what drives the mechanism behind these effects. Low methodological quality, high heterogeneity and complexity, the characteristics of the included samples, and often high attrition rates challenge the investigation of the effectiveness and the making of sound inferences about the effect sizes and significance of the results. To address this, new studies and methods are needed. A megastudy design in which different interventions are evaluated in the same population over the same period on the same outcomes may solve some of the challenges.

The association between physical activity and musculoskeletal disorders-a cross-sectional study of teachers

Purpose

Combined with insufficient physical activity (PA) prolonged and improperly performed sedentary work can lead to musculoskeletal disorders (MSDs). The aim of this study was (I) to evaluate the self-reported level of PA and the prevalence of MSDs in male and female teachers, and (II) to investigate the association between PA and MSDs in teachers in Polish primary and secondary schools.

Methods

The study included 254 teachers from primary and secondary schools from Upper Silesia, Poland, excluding physical education teachers. The level of PA was assessed using the Seven-Day Physical Activity Recall (SDPAR). A standardized Nordic Musculoskeletal Questionnaire (NMQ) was used to assess the prevalence of MSDs.

Results

A similar percentage of female (80%) and male (90%) teachers met the WHO recommendations on moderate-intensity PA. The recommendations on performing vigorous-intensity PA were met by significantly (p = 0.002) less female than male teachers (50% and 75% respectively). Lower back disorders during the last 12 months and the last 7 days (57% and 45%, respectively) were the most commonly reported MSDs by teachers, followed by neck (53%, 40%), upper back (39%, 28%), and knee disorders (37%, 26%). The highest pain intensity was experienced by the teachers in the lower back and neck. Teachers with a greater number of MSDs were less likely to engage in vigorous-intensity PA and total PA than those with fewer painful areas of the body. Pain intensity in the neck, knees, upper- and lower back, and wrists/hands was negatively related to moderate and total PA. BMI negatively correlated with total PA, moderate-intensity PA vigorous-intensity PA, and high vigorous-intensity PA.

Conclusions

The study revealed the association between PA and MSDs in studied teachers. The most of the studied teachers met the WHO recommendation, and women were less likely to perform vigorous and high-vigorous PA than men. The lower back and neck disorders were the most common among the teachers.

Leisure, Mental Health, and Life Satisfaction among Older Adults with Mild Cognitive Impairment

Objectives: Little research has investigated the relationship between types of leisure activities and mental health outcomes among older adults with mild cognitive impairment (MCI). The purpose of this study was to investigate how certain leisure activities are associated with life satisfaction, anxiety, loneliness, happiness, and positive and negative affect. Methods: In this study, we used the 2020 Health and Retirement Study Core Early data and conducted a hierarchical regression analysis to investigate the different effects of the 3 types of leisure activities on the mental health of older adults with MCI (N=901). Results: We found that leisure-time physical activity was the strongest predictor of enhanced life satisfaction, positive affect, and happiness, and reduced anxiety and loneliness. In addition, sedentary leisure was associated with reduced anxiety and loneliness and increased happiness. Conclusions: These findings suggest that engagement in leisure-time physical activity and sedentary leisure can be instrumental in promoting the life satisfaction and mental health of older adults with mild cognitive impairment.

Psychosocial Working Conditions and Subsequent Sickness Absence-Effects of Pain and Common Mental Disorders in a Population-Based Swedish Twin Sample

OBJECTIVE

To investigate pain and/or common mental disorders (CMDs) in the associations between psychosocial working conditions and sickness absence (SA) while controlling familial confounding.

METHODS

Prospective Prospective twin cohort study included survey data for pain and CMD, register data for SA and psychosocial working conditions. The follow-up from 2005 to 2016 of 28,916 twin individuals for first incident SA spell measured as the main International Classification of Diseases version 10 (ICD-10) diagnosis groups (F00-F99, I00-I99, and M00-M99), or the duration. We used regression models to obtain odds ratio (OR), incidence rate ratio (IRR), or relative risk ratio (RRR) with 95% confidence intervals (CI).

RESULTS

The covariate adjusted models of 9156 SA spells indicated almost no statistically significant associations between psychosocial working conditions and SA.

CONCLUSIONS

Psychosocial working conditions were not associated with SA while familial confounding could not be ruled out.

The relationship between telework from home and employee health: a systematic review

BACKGROUND

Globalization and technological progress have made telework arrangements such as telework from home (TWFH) well-established in modern economies. TWFH was rapidly and widely implemented to reduce virus spread during the Coronavirus disease (COVID-19) pandemic, and will probably be widespread also post-pandemic. How such work arrangements affect employee health is largely unknown. Main objective of this review was to assess the evidence on the relationship between TWFH and employee health.

METHODS

We conducted electronic searches in MEDLINE, Embase, Amed, PsycINFO, PubMed, and Scopus for peer-reviewed, original research with quantitative design published from January 2010 to February 2021. Our aim was to assess the evidence for associations between TWFH and health-related outcomes in employed office workers. Risk of bias in each study was evaluated by the Newcastle-Ottawa Scale and the collected body of evidence was evaluated using the the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.

RESULTS

We included 14 relevant studies (22,919 participants) reporting on 28 outcomes, which were sorted into six outcome categories (general health, pain, well-being, stress, exhaustion & burnout, and satisfaction with overall life & leisure). Few studies, with many having suboptimal designs and/or other methodological issues, investigating a limited number of outcomes, resulted in the body of evidence for the detected outcome categories being GRADED either as low or very low.

CONCLUSIONS

The consisting evidence on the relationship between TWFH and employee health is scarce. The non-existence of studies on many relevant and important health outcomes indicates a vast knowledge gap that is crucial to fill when determining how to implement TWFH in the future working life.

Sport and physical activity participation in the workplace: the role of employees' self-perception

Purpose

Despite preventive efforts from some companies to offer some sport and physical activity (SPA) to their employees, French participation rates remain very low, which limit impacts in terms of health and economic benefits. The aim of this study was to better understand the factors influencing SPA participation in the workplace.

Design/methodology/approach

A cross-sectional study was conducted based on an electronic questionnaire survey disseminated to 24 companies based in France that offered SPA to their employees. An independent sample t-test was conducted to explore the differences between the most common facilitating and constraining factors, in relation to “being a sporty person” self-perception, leisure-time physical activity (LTPA) level and demographic information. Predictors of SPA in the workplace were determined using a binomial logistic regression.

Findings

A total of 1,318 employees completed the survey, of which 60% were women, mostly highly educated and white collar. “Being a sporty person,” self-perception has been a predictor of SPA participation in the workplace.

Practical implications

More multicomponent work-based interventions, including incidental physical activity, might be necessary to increase participation and overcome time constraint.

Originality/value

Although SPA participation in the workplace is considered to promote numerous positive organizational and individual consequences, this is the first study to assess the associations between facilitating and constraining factors of SPA participation in the workplace setting and physical self-perception.

The lost productivity cost of absenteeism due to COVID-19 in health care workers in Iran: a case study in the hospitals of Mashhad University of Medical Sciences

Background

Human resources management plays an important role in social development and economic growth. Absence from work due to health problems can make obstacles to the growth of economy. This study conducted aimed to estimate the absenteeism costs of COVID-19 among the personnel of hospitals affiliated to Mashhad University of Medical Sciences in Mashhad, Iran.

Methods

This cross-sectional study was conducted between February 19, 2020, and September 21, 2020. The absenteeism costs were calculated using the human capital approach. Finally, we applied the linear regression to assess the impact of variables on the lost productivity of absenteeism due to COVID-19 among the personnel of hospitals affiliated to Mashhad University of Medical Sciences.

Results

The results of this study showed that 1958 personnel had COVID-19. The total of absenteeism days in our study were 32,209 days, with an average of 16.44 absenteeism days. Total costs due to absenteeism were estimated to be nearly $1.3 million, with an average of $671.4 per patient. The results of regression model showed that gender (male), age (> 50 years), employment Type (non-permanent) and monthly income had a positive relationship with the absenteeism cost. Also, there are a negative significant relationship between absenteeism cost with job (physicians) and work experience.

Conclusions

Absenteeism costs of COVID-19 in the hospitals of Mashhad University of Medical Sciences represent a significant economic burden. The findings of our study emphasize the emergency strategies to prevent and control COVID-19 among the healthcare workers. It can decrease the economic impacts of COVID-19 and improve human resources management during the COVID-19 pandemic.

Metabolic syndrome and the increased risk of medically-certified long-term sickness absence: a prospective analysis among Japanese workers

BACKGROUND

Metabolic syndrome (MetS) has been associated with various chronic diseases which may lead to long-term sickness absence (LTSA), but there is lacking information on the direct association between MetS and LTSA. The present study aimed to investigate the all-cause and cause-specific associations between MetS and the risk of medically-certified LTSA among Japanese workers.

METHOD

We recruited 67,403 workers (57,276 men and 10,127 women), aged 20-59 years, of 13 companies in Japan, during their health check-ups in 2011 (11 companies) and 2014 (2 companies), and followed them up for LTSA events (≥ 30 consecutive days) until March 31, 2020. MetS was defined according to the Joint Interim Statement. A Cox proportional hazards regression model was used to estimate hazard ratio (HR) and its 95% confidence interval (CI) for LTSA associated with MetS and its components.

RESULTS

During 408,324 person-years of follow-up, 2,915 workers experienced LTSA. The adjusted HR for all-cause LTSA was 1.54 (95% CI, 1.41-1.68) among those with vs without MetS. In cause-specific analysis, HRs associated with MetS significantly increased for LTSA due to overall physical disorders (1.76), cardiovascular diseases (3.16), diseases of the musculoskeletal system and connective tissue (2.01), cancers (1.24), obesity-related cancers (1.35), mental, behavioral and neurodevelopmental disorders (1.28), reaction to severe stress and adjustment disorders (1.46) and external causes (1.46). The number of MetS components were also significantly associated with increased LTSA risk.

CONCLUSION

MetS was associated with an increase in the risk of LTSA due to various diseases among Japanese workers.

Musculoskeletal disorders and the physical activity of territorial army soldiers during the COVID-19 pandemic

BACKGROUND

The aim of this study was to assess the occurrence of self-reported musculoskeletal disorders (MSD) among Polish territorial army soldiers during the COVID-19 pandemic and to investigate whether there was a relationship between occupational physical activity (OPA), leisure time physical activity (LTPA), and MSD.

METHODS

The study used a cross-sectional design with a sample of 373 territorial army soldiers ages 18-55 who had not previously suffered from COVID-19 and were not convalescents. The symptoms prevalence data was collected using the standardized Nordic Musculoskeletal Questionnaire. OPA and LTPA data was collected using the Seven-Day Physical Activity Recall (SDPAR).

RESULTS

The OPA, LTPA, and total physical activity (PA) among the studied soldiers was very diverse and the mean level of PA was relatively high. A total of 56 and 40% of territorial army soldiers had experienced pain or other discomfort in one or more of nine body regions during the past 12 months and during the past 7 days, respectively. The most common MSD among Polish territorial army soldiers were low back pain, followed by pain in the neck and knees.

CONCLUSIONS

The study revealed that the OPA of the studied soldiers, especially vigorous-intensity and high vigorous-intensity OPA, was associated with a higher prevalence of MSD in several regions of the body, i.e. the lower back, elbows, wrists or hands, hips or thighs, and ankles or feet. Along with the increase in energy expenditure on total PA, a greater percentage of respondents experienced low back pain. Vigorous and high vigorous-intensity PA may contribute to the occurrence of MSD.

Leisure-Time Physical Activity Reduces the Risk of Long-Term Sickness Absence Among Older Healthy Female Eldercare Workers

PURPOSE

This study aimed to examine the association between leisure-time physical activity (PA) and risk of long-term sickness absence (LTSA).

DESIGN

Data on LTSA (≥3 consecutive weeks during a 1-year follow-up) were acquired from the Danish Register for Evaluation of Marginalization and linked to a questionnaire via personal identification number.

SETTING

Eldercare workers from 36 Danish municipalities.

SUBJECTS

Data were retrieved from 4605 healthy Danish female eldercare (i.e., workers assisting senior citizens with daily activities and health) aged 19 to 69 years, who answered a questionnaire on health, and work environment in 2005.

MEASURES

Calculated risk of LTSA and its association with self-reported leisure-time PA.

ANALYSIS

A Cox proportional hazards model was used to calculate adjusted hazard ratios (HR) and 95% confidence intervals (95% CI).

RESULTS

Eldercare workers showed significantly reduced risk of LTSA when performing moderate (HR = 0.67, 95%CI 0.47-0.96), and vigorous leisure-time PA (HR = 0.45, 95%CI 0.25-0.81) (reference group: sedentary). In subgroup analyses, females over 45 years showed a risk reduction of LTSA for moderate (HR = 0.54, 95%CI 0.32-0.90), and vigorous leisure-time PA (HR = 0.43, 95%CI 0.18-0.99), whereas younger eldercare workers did not show significant risk reductions for either moderate (HR = 0.86, 95%CI 0.51-1.43) or vigorous leisure-time PA (HR = 0.50, 95%CI 0.21-1.16) in the fully adjusted model.

CONCLUSIONS

The results indicate that moderate and, particularly, vigorous leisure-time PA reduced risk of LTSA in eldercare workers aged over 45 years.

Work-Time Compositions of Physical Behaviors and Trajectories of Sick Leave Due to Musculoskeletal Pain

We aimed to investigate the association between work-time compositions of physical behavior and sick leave trajectories due to musculoskeletal pain over one year. We conducted a secondary analysis using the data of 981 workers in a Danish prospective cohort (DPHACTO 2012–2014). At baseline, we assessed physical behaviors (sitting, standing, light physical activity (LIPA), and moderate-to-vigorous physical activity (MVPA)) at work and during leisure, using accelerometers. Over 1 year follow-up, workers reported sick-leave days due to musculoskeletal pain at 4-week intervals. Four distinct trajectories of sick leave were previously identified in this cohort (“no sick leave”, “few days—increasing trajectory”, “some days—decreasing trajectory”, “some days—increasing trajectory”), and used as an outcome in multinomial regression models with work-time compositions as predictors, adjusted for compositions of behavior during leisure, age, sex, body mass index, and smoking habits. More time spent sitting relative to the other behaviors was negatively associated with the trajectory of few days—increasing sick leave (p = 0.004), while time in LIPA was positively associated with the trajectory of some days—increasing sick leave (p = 0.009). Standing and MVPA were not significantly associated with sick leave trajectories. In conclusion, work-time compositions with more sitting relative to the other behaviors had lower risk for an increasing trajectory of sick leave due to pain, while compositions with more LIPA had higher risk. This may have implications for prevention of pain-related sick leave in blue-collar workers.

Timing matters: worker absenteeism in a weekly backward rotating shift model

OBJECTIVES

We analyze the impact of the positioning of shifts (morning, afternoon, night) on worker absenteeism in a large German automobile plant.

METHODS

Using a completely balanced panel of 153 organizational units over the 2-year-period 2009 to 2010 (i.e. 104 consecutive weeks with 15,912 unit-week-observations) we estimate a series of GLM and Fixed Effects models.

RESULTS

Our main finding is that during afternoon shifts absence rates are significantly higher than during either morning or night shifts and that absence rates are particularly high during the afternoon shift immediately following the 3 weeks of consecutive night shifts. We attribute our first finding to the "social opportunity costs" of working and the second one to a "tax evasion effect".

CONCLUSIONS

When designing new shift models, firms should try to anticipate their workers' reaction to avoid unintended incentives.
