Interventions to promote work ability by increasing physical activity among workers with physically strenuous jobs: A scoping review

Precision prevention in worksite health-A scoping review on research trends and gaps

OBJECTIVES

To map the current state of precision prevention research in the workplace setting, specifically to study contexts and characteristics, and to analyze the precision prevention approach in the stages of risk assessment/data monitoring, data analytics, and the health promotion interventions implemented.

METHODS

Six international databases were searched for studies published between January 2010 and May 2023, using the term "precision prevention" or its synonyms in the context of worksite health promotion.

RESULTS

After screening 3,249 articles, 129 studies were reviewed. Around three-quarters of the studies addressed an intervention (95/129, 74%). Only 14% (18/129) of the articles primarily focused on risk assessment and data monitoring, and 12% of the articles (16/129) mainly included data analytics studies. Most of the studies focused on behavioral outcomes (61/160, 38%), followed by psychological (37/160, 23%) and physiological (31/160, 19%) outcomes of health (multiple answers were possible). In terms of study designs, randomized controlled trials were used in more than a third of all studies (39%), followed by cross-sectional studies (18%), while newer designs (e.g., just-in-time-adaptive-interventions) are currently rarely used. The main data analyses of all studies were regression analyses (44% with analyses of variance or linear mixed models), whereas machine learning methods (e.g., Algorithms, Markov Models) were conducted only in 8% of the articles.

DISCUSSION

Although there is a growing number of precision prevention studies in the workplace, there are still research gaps in applying new data analysis methods (e.g., machine learning) and implementing innovative study designs. In the future, it is desirable to take a holistic approach to precision prevention in the workplace that encompasses all the stages of precision prevention (risk assessment/data monitoring, data analytics and interventions) and links them together as a cycle.

Profiles of work ability and associated factors in young and middle-aged acute myocardial infarction patients: A latent profile analysis

BACKGROUND

The incidence of acute myocardial infarction (AMI) is increasing among young and middle-aged people, and such patients need to be reemployed after AMI events from the individual and society perspectives. However, the situation of employment after AMI was not ideal. Early identification of patients vulnerable to decreased work ability and provided targeted intervention may be beneficial.

OBJECTIVE

To identify the profiles and associated factors of work ability in young and middle-aged AMI patients.

METHODS

A cross-sectional study was conducted in Guangzhou, China, from September 2022 to October 2023. Work ability, self-efficacy for return-to-work, social support, anxiety, and depression were measured by the Work-ability Support Scale (WSS), Return-To-Work Self-Efficacy Questionnaire, Social Support Rating Scale, 7-item Generalized Anxiety Disorder Scale, and Patient Health Questionnaire 9, respectively. We performed latent profile analysis based on three subdomains of the WSS by using Mplus 8.3. Multiple logistic regression was used to identify factors associated with work ability.

RESULTS

A total of 155 participants (aged 48.58±7.153 years, 95.5 % male) were included. We identified three latent profiles of work ability: low work ability (28.1 %), moderate work ability (51 %), and high work ability (20.6 %). The per capita monthly household income, NYHA functional class, total cholesterol, length of hospital stay, social support, and self-efficacy for return-to-work were factors associated with work ability.

CONCLUSION

This study demonstrated different profiles and associated factors of work ability in young and middle-aged AMI patients. It is suggested that healthcare providers identify and monitor associated factors to improve work ability among this subpopulation.

Tiredness after work associates with less leisure-time physical activity

Physical activities and sedentary behaviors take place in different contexts. This study aimed to determine if the context, total score, and leisure-time MET-index assessed by the Baecke questionnaire associate with each other or with sedentary behavior and physical activity outcomes from a 4-week accelerometer measurement in physically inactive adults with overweight. The item "After working I am tired" correlated negatively with items related to leisure-time physical activity and sports participation. The total Baecke Score showed weak but significant correlations with accelerometer-measured sedentary behavior, physical activity, daily steps, and mean activity intensity of the day (r = - 0.33, 0.41, 0.35, and 0.41, respectively). The associations strengthened when the Sport Index was omitted from the Score. The leisure-time MET-Index did not correlate with accelerometer-measured sedentary behavior or physical activity. Tiredness after working associated with less self-reported physical activity during leisure time. This suggests that better recovery from work-related stress could increase leisure-time physical activity, or increasing leisure-time physical activity could reduce tiredness after working. Moreover, among self-reportedly inactive adults with overweight, focusing the questionnaire on work and non-sport leisure time instead of total time might give more accurate estimates of sedentary behavior and physical activity when compared to accelerometry.The study is registered at ClinicalTrials.gov (NCT03101228, 05/04/2017).

Acute Effects of a Warm-Up Intervention on Pain, Productivity, Physical Capacities and Psychological Perceptions Among Vineyard Workers: a Cluster Randomized Trial

PURPOSE

Agriculture is one of the sectors that are the most concerned by musculoskeletal disorders (MSDs). Workplace physical activity programs are one of the most promising solutions to prevent adverse consequences of MSDs such as pain or impairment in physical capacities. The aims of this study were twofold: (1) to investigate the acute effect of a warm-up session on pain, work performance, physical capacities and psychosocial perceptions among vineyard workers; (2) to determine the most beneficial warm-up modality for vineyard workers.

METHODS

A cluster randomized study was implemented among 92 French vineyard workers. A 15 min single session of warm-up was implemented among four groups corresponding to four different conditions: (1) hybrid warm-up intervention (HWU); (2) dynamic warm-up intervention (DWU); (3) stretching warm-up intervention (SWU); (4) no warm-up intervention (CONTROL).

RESULTS

DWU showed significant increased performance (p < 0.05), increased heart rate (p < 0.001), better readiness to work (p < 0.05) and lower workload (p < 0.05) than the CONTROL. HWU showed a better readiness to work (p < 0.01). SWU showed better work quality (p < 0.05). However, the three different warm-up protocols did significantly not differ from the CONTROL group in terms of perceived pain intensity, and physical capacities.

CONCLUSION

The present findings confirm some beneficial acute effects on performance, heart rate and psychological perceptions of a single warm-up session performed before pruning. The DWU seems to be the most beneficial warm-up modality.

Effectiveness of worksite wellness programs based on physical activity to improve workers' health and productivity: a systematic review

BACKGROUND

Although the scientific literature has previously described the impact of worksite programs based on physical activity (WPPAs) on employees' productivity and health in different contexts, the effect of these programs has not been analyzed based on the characteristics or modalities of physical activity (PA) performed (e.g., aerobic exercise, strength training, flexibility). In addition, studies on WPPAs usually report health and productivity outcomes separately, not integrated into a single study. Knowing the health and economic-related impacts of a WPPAs could provide useful information for stakeholders and policy development.

OBJECTIVE

The purpose of this review was as follows: (1) to analyze the effect of different modalities of WPPAs on employees' productivity and health and (2) to investigate the economic impact of WPPAs.

METHODS

This systematic review is registered in PROSPERO (CRD42021230626) and complies with PRISMA guidelines. Only randomized controlled trials from 1997 to March 2021 were included. Two reviewers independently screened abstracts and full texts for study eligibility, extracted the data, and performed a quality assessment using the Cochrane Collaboration Risk-of-Bias Tool for randomized trials. Population, instruments, comparison, and outcome (PICO) elements were used to define eligibility criteria. Eight-hundred sixty relevant studies were found through electronic searches in PubMed, Web of Science, Medline, Scopus, and SPORTDiscus databases. Once the eligibility criteria were applied, a total of 16 papers were included.

RESULTS

Workability was the productivity variable most positively impacted by WPPAs. Cardiorespiratory fitness, muscle strength, and musculoskeletal symptoms health variables improved in all the studies included. It was not possible to fully examine the effectiveness of each exercise modality because of the heterogeneity in methodology, duration, and working population. Finally, cost-effectiveness could not be analyzed because this information was not reported in most studies.

CONCLUSION

All types of WPPAs analyzed improved workers' productivity and health. However, the heterogeneity of WPPAs does not allow to identify which modality is more effective.

Increased physical workload in home care service is associated with reduced recovery from work

OBJECTIVE

This study investigated the physical workload of home care service workers and determined whether the different intensities of physical work strain experienced by home care nurses have different impacts on their recovery from work.

METHODS

Physical workload and recovery were measured among 95 home care nurses based on heart rate (HR) and heart rate variability (HRV) recordings during one work shift and the following night. Differences in the physical work strain were compared between younger (≤ 44-year-old) and older (≥ 45-year-old) employees and between morning and evening shifts. To determine the effects of occupational physical activity on recovery, HRV at all time points (during the workday, when awake and asleep, and whole measurement) in relation to the amount of occupational physical activity was examined.

RESULTS

The average physiological strain during the work shift, measured as metabolic equivalent (MET), was 1.8 ± 0.5. Moreover, the occupational physical demands in relation to maximal capacity were higher for the older employees. The results of the study showed that a higher occupational physical workload reduced the HRV of home care workers during the workday, leisure time, and sleep.

CONCLUSIONS

These data indicate that increased occupational physical workload is associated with reduced recovery among home care workers. Therefore, decreasing occupational strain and ensuring sufficient recovery is recommended.

Self-reported competence level of occupational health care professionals in work ability risk management and analysis

BACKGROUND

The management and analysis of work ability risks is important to support well-being at work and requires multidimensional competence. Competence evaluation in Occupational Health Care professionals' (OHCP) practice is essential for their professional development and promotion of quality of care.

OBJECTIVE

To describe OHCPs' self-reported competence level to manage and analyze work ability risks.

METHODS

A descriptive, cross-sectional study design was applied. The data were collected electronically from May to June 2018 using the Comp-WARMA instrument (scale 1 = poor - 4 = excellent) from Occupational Health Care professionals working in Finnish private medical centers (n = 169, response rate of 10%). The data were analyzed statistically.

RESULTS

The levels of knowledge and skills of OHCP in work ability risk management and analysis were mainly at good level (3.22 on average), but some deficient were still identified. The knowledge and skills of the work ability risk management and analysis were associated with the number of customer organizations they worked with, their attendance of supplementary training regarding work ability risk management and analysis, their amount of work experience, their type of employment, age, and gender.

CONCLUSION

OHCP self-reported competence levels in work ability risk management and analysis was at good level. There is a need for development in all areas of work ability risk management and analysis. OHCP could benefit from in-service education on work ability risk management and analysis. Further validation of the Comp-WARMA instrument in larger sample is needed.

Calibrating a Comprehensive Immune Age Metric to Analyze the Cross Sectional Age-Related Decline in Cardiorespiratory Fitness

Cardiorespiratory fitness (CRF) is essential for sustained work ability in good health, but declines with aging, as does the functionality of the immune system, the latter process commonly referred to as immunosenescence. This study aimed to compare the capacity of immunosenescence biomarkers with chronological age for predicting low CRF in a cross-sectional sample recruited from the regional working population. CRF was determined by submaximal bicycle ergometer testing in a cross-sectional sample of 597 volunteers aged 20-70 years from the 'Dortmund Vital Study' (DVS, ClinicalTrials.gov Identifier: NCT05155397). Low CRF was scored if the ergometer test was not completed due to medical reasons or if the power output projected to a heart rate of 130 bpm divided by body mass was below sex-specific reference values of 1.25 W/kg for females and 1.5 W/kg for males, respectively. In addition to established biomarkers of immunosenescence, we calibrated a comprehensive metric of immune age to our data and compared its predictive capacity for low CRF to chronological age, while adjusting our analysis for the influence of sex, obesity, and the level of regular physical activity, by applying univariate and multiple logistic regression. While obesity, low physical activity, chronological and immune age were all associated with increased probability for low CRF in univariate analyses, multiple logistic regression revealed that obesity and physical activity together with immune age, but not chronological age, were statistically significant predictors of low CRF outcome. Sex was non-significant due to the applied sex-specific reference values. These results demonstrate that biological age assessed by our immunological metric can outperform chronological age as a predictor for CRF and indicate a potential role for immunosenescence in explaining the inter-individual variability of the age-related decline in cardiorespiratory fitness.

Factors Influencing Long-Term Care Workers' Self-Efficacy for Encouraging Residents to Engage in Physical Activity

We aimed to assess work-related factors and their association with long-term care workers' self-efficacy for encouraging and engaging residents in physical activity. Baseline data from a worksite wellness study with 98 workers were used. We used a linear regression model, to assess if job satisfaction, work ability, and social support for staff health behaviors from coworkers and supervisors were associated with staffs' self-efficacy for Function-Focused Care (FFC) and Staffs' Outcome Expectations for FFC. Staffs' social support for healthy behaviors from coworkers was the only factor that was significantly associated with Staffs' Outcome Expectations for FFC and staffs' self-efficacy-FFC, respectively explaining 19% and 14% of the variance. Our findings show that staffs' social support from coworkers is associated with higher self-efficacy for encouraging and engaging residents in physical activity suggests future worksite wellness studies with long-term care workers may wish to consider assessing program impacts on residents' physical activity levels.
