Abstract [en]

In a context of job rotation, this study determined the extent to which the difficulty of a cognitive task (CT) interspersed between bouts of repetitive, low-intensity work (pipetting) influences recovery from fatigue. Fifteen participants performed three experimental sessions, each comprising 10 repeats of a 7 min + 3 min combination of pipetting and CT. The CT was easy, moderate or hard. Surface electromyography (EMG amplitude of the forearm extensor and trapezius muscles) and self-reports was used to assess fatigability. Perceived fatigue and trapezius EMG amplitude increased during sessions. CT difficulty influenced fatigue development only little, besides forearm extensor EMG increasing more in CT3 than in CT1 and CT2. During CT bouts, fatigability recovered, and to a similar extent irrespective of CT. Thus, CT difficulty influenced recovery of perceived as well as performance fatigability to a minor extent, and may not be a critical issue in job rotation comprising alternating physical and cognitive tasks.

Abstract [en]

The aim of this study was to develop and evaluate calibration models to predict objectively measured time spent sitting, standing and walking during office work from self-reported time-use compositions using a compositional data analysis (CoDA) approach. Ninety-nine office workers (49 women) at the Swedish Transport Administration participated in an intervention study on relocation to activity-based offices. At baseline and at a 3-months follow-up, physical behaviours (sitting, standing and walking) at work were assessed for five days using a thigh-mounted accelerometer (Actigraph) and by self-report (IPAQ). The time-use composition of the three behaviours was expressed in terms of isometric log-ratios (ILR). Calibration models predicting accelerometry-based time-use from self-reported compositions were constructed using linear regression on baseline data, and then validated using follow-up data. The accelerometer data showed that, on average, workers spent 69.9% of their day sitting, 23.7% standing, and 6.4% walking. The corresponding percentages for self-reports were 71.7%, 21.6%, and 7.4%, respectively. Non-calibrated self-reports were biased: the RMS errors obtained from the ILRs expressing sitting, standing and walking were 0.73, 1.09 and 1.05, respectively. Calibration models reduced these errors by 45% (sitting), 56% (standing), and 76% (walking). Validation of the calibration models using follow-up data from the same workers showed calibration remained equally effective; RMS errors were reduced by 55% (sitting), 58% (standing), and 75% (walking). In conclusion, calibration models for compositional time-use data were effective in reducing bias in self-reported physical behaviours at work, and the models remained effective when used on new data from the same workers. Calibrated self-reports may represent a cost-effective method for obtaining physical behaviour data with a satisfying accuracy in large-scale cohort and intervention studies.

Abstract [en]

Objective: To determine the extent to which male and female office workers differ in their time-use composition of sitting behaviors (SB) and physical activity (PA) during work and leisure.

Methods: SB and PA was measured using thigh-worn accelerometers for up to 8 full days in 77 male and 104 female office workers. Daily time-use compositions during work and leisure were described in four exhaustive categories, i.e. sitting in short (<30  min) and long (≥30 min) bouts, standing, and active behaviors. Following a compositional data analysis procedure, isometric log-ratios (ilr) were calculated to express time in sitting relative to non-sitting, short relative to long sitting bouts, and standing relative to active behaviors. Differences between sexes (men and women) and domains (work and leisure) were examined on the basis of these ilrs using ANOVA.

Results: At work, time spent sitting in short bouts, long bouts, standing, and active was, on average, 34%, 36%, 22% and 8% among men and 31%, 37%, 24% and 8% among women. Corresponding proportions during leisure were 34%, 25%, 28% and 13% among men and 29%, 28%, 31% and 12% among women. Time spent sitting relative to non-sitting differed significantly between work and leisure (ilr sitting-vs-non-sitting, partial eta squared=0.09, p<0.01). During leisure, men used proportionally more time than women in short sitting bouts (ilr short-vs-long, partial eta squared=0.06, p<0.01) and spent more time in active behaviors relative to standing (ilr standing-vs-active, partial eta squared=0.04, p<0.01). No significant sex differences were observed during work (p>0.05).

Conclusions:  The leisure behavior observed among men is probably more beneficial for health than that observed for women. However, both men and women spent a major proportion of their time sitting, both at and outside their office work, and they were, in general, only little active. Thus, both men and women could benefit from interventions to reduce SB and increase PA both at work and during leisure.

Abstract [en]

INTRODUCTION: Sit-stand workstations are a popular intervention to reduce sedentary behavior (SB) in office settings. However, the extent and distribution of SB in office workers long-term accustomed to using sit-stand workstations as a natural part of their work environment are largely unknown. In the present study, we aimed to describe patterns of SB in office workers with long-term access to sit-stand workstations and to determine the extent to which these patterns vary between days and workers. METHODS: SB was objectively monitored using thigh-worn accelerometers for a full week in 24 office workers who had been equipped with a sit-stand workstation for at least 10 months. A comprehensive set of variables describing SB was calculated for each workday and worker, and distributions of these variables between days and workers were examined. RESULTS: On average, workers spent 68% work time sitting [standard deviation (SD) between workers and between days (within worker): 10.4 and 18.2%]; workers changed from sitting to standing/walking 3.2 times per hour (SDs 0.6 and 1.2 h-1); with bouts of sitting being 14.9 min long (SDs 4.2 and 8.5 min). About one-third of the workers spent >75% of their workday sitting. Between-workers variability was significantly different from zero only for percent work time sitting, while between-days (within-worker) variability was substantial for all SB variables. CONCLUSIONS: Office workers accustomed to using sit-stand workstations showed homogeneous patterns of SB when averaged across several days, except for percent work time seated. However, SB differed substantially between days for any individual worker. The finding that many workers were extensively sedentary suggests that just access to sit-stand workstations may not be a sufficient remedy against SB; additional personalized interventions reinforcing use may be needed. To this end, differences in SB between days should be acknowledged as a potentially valuable source of variation.

Abstract [en]

Objective: Emerging evidence suggests that excessive sitting has negative health effects. However, this evidence largely relies on research using self-reported sitting time, which is known to be biased. To correct this bias, we aimed at developing a calibration model estimating "true" sitting from self-reported sitting.

Methods: Occupational sitting time was estimated by self-reports (the International Physical Activity Questionnaire) and objective measurements (thigh-worn accelerometer) among 99 Swedish office workers at a governmental agency, at baseline and 3 and 12 months afterwards. Following compositional data analysis procedures, both sitting estimates were transformed into isometric log-ratios (ILR). This effectively addresses that times spent in various activities are inherently dependent and can be presented as values of only 0−100%. Linear regression was used to develop a simple calibration model estimating objectively measured "true" sitting ILR (dependent variable) from self-reported sitting ILR (independent variable). Additional self-reported variables were then added to construct a full calibration model. Performance of the models was assessed by root-mean-square (RMS) differences between estimated and objectively measured values. Models developed on baseline data were validated using the follow-up datasets.

Results: Uncalibrated self-reported sitting ILR showed an RMS error of 0.767. Simple and full calibration models (incorporating body mass index, office type, and gender) reduced this error to 0.422 (55%) and 0.398 (52%), respectively. In the validations, model performance decreased to 57%/62% (simple models) and 57%/62% (full models) for the two follow-up data sets, respectively.

Conclusions: Calibration adjusting for errors in self-reported sitting led to substantially more correct estimates of "true" sitting than uncalibrated self-reports. Validation indicated that model performance would change somewhat in new datasets and that full models perform no better than simple models, but calibration remained effective.

Abstract [en]

Purpose - The purpose of this paper is to 1) describe Lean maturity in primary care using a questionnaire based on Liker’s description of Lean, complemented with observations, and 2) determine the extent to which Lean maturity is associated with quality of care measured as staff-rated satisfaction with care and adherence to national guidelines. High Lean maturity indicates adoption of all Lean principles throughout the organization and by all staff.

Design/methodology/approach - Data were collected using a survey based on Liker’s four principles, divided into 16 items (n = 298 staff in 45 units). Complementary observations (n = 28 staff) were carried out at four units.

Findings - Lean maturity varied both between and within units. The highest Lean maturity was found for ‘adhering to routines’ and the lowest for ‘having a change agent at the unit’. Lean maturity was positively associated with satisfaction with care and with adherence to national guidelines to improve healthcare quality. 

Practical implications - Quality of primary care may benefit from increasing Lean maturity. When implementing Lean, managers could benefit from measuring and adopting Lean maturity repeatedly, addressing all Liker’s principles and using the results as guidance for further development.

Originality/value - This is one of the first studies to evaluate Lean maturity in primary care, addressing all Liker’s principles from the perspective of quality of care. The results suggest that repeated actions based on evaluations of Lean maturity may help to improve quality of care.

Abstract [en]

Objectives

In spite of preventive efforts, organizations and employees face several challenges related to working life and occupational health, such as a substantial prevalence of musculoskeletal disorders, social inequality in health and physical capacity, multi-morbidity, an obesity epidemic and an aging workforce. We argue that a new approach for occupational ergonomics and health is required, going beyond prevention of harm caused by work. We propose the ´Goldilocks Principle´ as a new approach of how productive work can be designed to literally promote health and physical capacity.

Methods                 

Physical (in)activity profoundly influences health and physical capacity, with effects depending on the extent and temporal structure of the (in)activity. Like the porridge, chair and bed that needed to be ‘just right’ for Goldilocks in the fairy-tale of ´The Three Bears´, physical activity during productive work needs to be ‘just right’ for promoting rather than deteriorating health and capacity. In many jobs, physical activity is, however, either ’too much/high/frequent’ or ’too little/low/infrequent’ to give positive biomechanical and cardiometabolic stimuli.

Results

The paper presents the rationale, concept, development, application and prospects of the Goldilocks Principle for how productive work can be designed to promote health and physical capacity.

Conclusions

We envision a great potential to promote health and physical capacity by designing productive work according to the Goldilocks Principle, thus leading to benefits with respect to the current challenges related to working life and occupational health for society, organizations and employees.

Abstract [en]

Objective: Understanding patterns of sedentary and physical activity (PA) behaviour in ‘blue-collar’ workers is an important prerequisite for effective interventions, and reduction of socioeconomic health inequalities. We conducted a systematic review of reported accelerometer data on these behaviours for non-office workers in ‘blue-collar’ industries.

Design: Systematic review.

Data sources: Cinahl, Embase, Medline, PubMed and Scopus (until 6th April 2018).

Eligibility Criteria: Accelerometer measured sedentary, sitting and/or PA behaviours in ‘blue collar’ workers (>10 participants). Two reviewers independently extracted data on participant characteristics, study protocols, and measured behaviours during work and/or non-work time.

Results: Eighteen studies, all from developed world economies, met inclusion criteria. Combined, or specific (construction, transport [drivers], manufacturing, cleaning, postal) industry samples were analysed using a range of devices, positions and analytical techniques (accelerometer counts, METs categories, or pattern recognition algorithms). Unlike office workers, ‘blue-collar’ workers were more sedentary, and less active, during non-work compared to work time (e.g. pattern recognition studies; sitting 5.3 vs 2.8 hours/day; moderate-to-vigorous PA 0.4 vs 0.7 hours/day).  Drivers were the most sedentary (work time 5.1 hours/day; non-work time 8.2 hours/day), with values 45% and 34% higher, respectively, than those reported in other ‘blue-collar’ workers.

Summary/Conclusions: Differences in work versus non-work exposure patterns highlight that translation of sedentary and PA interventions aimed at office workers to ‘blue-collar’ workers might lead to different health results, and thus be inefficient in reducing socioeconomic health inequalities. We also argue for consensus on common measurement and reporting methodologies, to better inform intervention efforts for priority, high risk workers.
