RESUMO

OBJECTIVE: To assess frontal plane motion of the pelvis and lumbar spine during 2 h of seated and standing office work and evaluate associations with transient low back pain. BACKGROUND: Although bending and twisting motions are cited as risk factors for low back injuries in occupational tasks, few studies have assessed frontal plane motion during sedentary exposures. METHODS: Twenty-one participants completed 2 h of seated and standing office work while pelvic obliquity, lumbar lateral bending angles, and ratings of perceived low back pain were recorded. Mean absolute angles were compared across 15-min blocks, amplitude probability distribution functions were calculated, and associations between lateral postures and low back pain were evaluated. RESULTS: Mean pelvic obliquity (sit = 4.0 ± 2.8°, stand = 3.5 ± 1.7°) and lumbar lateral bending (sit = 4.5 ± 2.5°, stand = 4.1 ± 1.6°) were consistently asymmetrical. Pelvic obliquity range of motion was 4.7° larger in standing (13.6 ± 7.5°) than sitting (8.9 ± 8.7°). In sitting, 52% (pelvis) and 71% (lumbar) of participants, and in standing, 71% (pelvis and lumbar) of participants, were considered asymmetric for >90% of the protocol. Lateral postures displayed weak to low correlations with peak low back pain (R ≤ 0.388). CONCLUSION: The majority of participants displayed lateral asymmetries for the pelvis and lumbar spine within 5° of their upright standing posture. APPLICATION: In short-term sedentary exposures, associations between lateral postures and pain indicated that as the range in lateral postures increases there may be an increased possibility of pain.

RESUMO

SUMMARY: The anterior cruciate ligament (ACL) is the most commonly injured knee ligament. Currently there are two commonly used surgical procedures: middle third patellar tendon grafts (bone-patellar tendon-bone: BTB) and semitendinosus autografts or semitendinosus combined with gracilis tendon autografts (ST/G). Purpose. The aim of this study is to compare the rehabilitation results over time of amateur sportsmen who have undergone anterior cruciate ligament (ACL) reconstruction surgery by means of one of the two most commonly used procedures: middle third patellar tendon grafts (bone-patellar tendon-bone: BTB) and semitendinosus and gracilis tendon autografts (ST/G). Method. 30 subjects divided into two groups, (15 BTB and 15 ST / G), were evaluated during rehabilitation and at three follow-up periods (16 weeks, 24 weeks, 2 years). Evaluation involved clinical examination, isokinetic tests, and functional rating scales: Lysholm and IKDC. Results. The clinical evaluation resulted in the following mean values: the value of the Lysholm score was 78 in both group at 16 weeks, 91 in group A and 94 in group B at 24 weeks, 98 in group A and 99 in group B at 2 years; the value of the IKDC score was 14 in group A and 15 in group B at 16 weeks, 12 in group A and 14 in group B at 24 weeks, 14 in group A and 15 in group B at 2 years. No major complications occurred during rehabilatation Conclusions. Subjects in both groups showed good neoligament stability up to the 24-week follow up. At the 2-year follow-up the subjects of group B showed poor neoligament stability that prevented the return to the previous level of sporting activity; all the subjects with high intensity sports activity needed a greater muscle strengthening. No statistically significant differences between the two groups are seen.

RESUMO

The aim of this study was to compare the associations between indicators of energy intake and expenditure with excess weight and obesity in women who work full-time in sedentary and less sedentary jobs. Data were from 3444 participants the Australian Longitudinal Study on Women's Health, who reported their weight, dietary intake, physical activity and occupation in 2009 (baseline), and weight in 2012 (follow-up). Participants were categorised as being in a 'less sedentary' or 'sedentary' job, based on occupational activity patterns. Odds of excess weight (BMI ≥ 25) at baseline and of being obese (BMI ≥ 30) at follow-up, by indicators of energy intake and expenditure, were compared in the two occupational groups. In multivariate analyses, high non-work sitting time and saturated fat intake were associated with increased odds of obesity at 3-year follow-up in both occupational groups. In the sedentary job group, high physical activity (in leisure and transport) was associated with a 51% reduction in odds of obesity (OR 0.49, 95%CI 0.25-0.97). In the less-sedentary job group, energy intake and high soft drink consumption were associated with markedly increased odds of obesity (OR 1.67 95%CI 1.07-2.61; OR 2.08 95%CI1.42-3.05, respectively). In this cohort of young Australian women, sedentariness at work did not markedly affect the prevalence of excess weight or obesity. Indicators of high energy intake and low energy expenditure were associated with increased odds of both excess weight and obesity, regardless of sedentariness of occupational group.

RESUMO

BACKGROUND: Multicomponent workplace-based interventions aimed at reducing sitting time among office workers are becoming increasingly popular. 'Take a Stand!' was such an intervention, reducing sitting time by 71 min after 1 month and 48 min after 3 months. However, it is unclear how the implementation process of 'Take a Stand!' affected these results. The present study explored how individual factors and organizational context influenced implementation and effect in 'Take a Stand!' METHODS: This was a mixed-methods study, combining data from interviews, questionnaires and accelerometers. Directed content analysis was used for analysing interviews with participants, ambassadors and managers from the 10 intervention offices in the 'Take a Stand!' STUDY: Categories for analysis were taken from Framework for Evaluating Organizational-level Interventions. Interview data were combined with questionnaire and activity data, and multilevel analysis was undertaken to assess how changes in sitting time varied depending on the assessed factors. In addition, interview data were used to underpin results from the multilevel analysis. RESULTS: Concurrent institutional changes were found to be a barrier for the intervention by ambassadors, while participants and managers did not find it to be an issue. Management support was consistently highlighted as very important. Participants evaluated ambassadors as being generally adequately active but also, that the role had a greater potential. The motivational and social aspects of the intervention were considered important for the effect. This was supported by regression analyses, which showed that a strong desire to change sitting time habits, strong motivation towards the project, and a high sense of collective engagement were associated to less sitting time at 3 months of about 30 min/8 h working day compared to participants with low scores. Influence from other participants (e.g. seeing others raise their tables) and the use of humour were continuously highlighted by participants as positive for implementation. Finally, the intervention was found to influence the social climate at the workplace positively. CONCLUSION: Individual motivation was related to the sitting time effect of 'Take a Stand!', but the organizational culture was relevant both to the implementation and effect within the office community. The organizational culture included among others to ensure general participation, to uphold management and peer-support, and maintain a positive environment during the intervention period.

RESUMO

Sit-stand desks are popular however many people have standing-induced low back pain (LBP). People with LBP have fewer standing weight shifts compared with back-healthy people. Participants were classified as standing-tolerant or intolerant. Participants were provided sit-stand desks for 12 weeks. Participants were assigned to intervention (graded standing exposure and exercise) or control (no instruction) conditions. Participants reported weekly sitting time and average/worst LBP. Standing weight shifts and LBP were re-assessed post-intervention. All groups decreased sitting time (range: 30-50%) over 12 weeks. Sitting time and average LBP were correlated in all standing-intolerant individuals, worst LBP and sitting time were correlated for intervention group only. All standing-intolerant individuals increased standing weight shifts and decreased LBP after 12-weeks. Standing-intolerant individuals benefitted from 12-weeks of sit-stand desk use regardless of intervention. Motivated individuals with standing-induced LBP may increase standing tolerance with sit-stand desk use. Additional benefits may exist when structured guidance is provided. Practitioner summary: Many people are standing-intolerant due to low back pain (LBP). This lab and field-based study showed some benefits from structured approaches to gradually progress standing time when transitioning to standing work. Using a sit-stand desk for 12 weeks resulted in decreased LBP and sitting time in standing-intolerant people.

RESUMO

OBJECTIVES: There is limited research on the association between sedentary behaviour and breast cancer risk, particularly whether sedentary behaviour is differentially associated with premenopausal and postmenopausal breast cancer. We pooled data from 2 case-control studies from Australia and Canada to investigate this association. METHODS: This pooled analysis included 1762 incident breast cancer cases and 2532 controls. Participants in both studies completed a lifetime occupational history and self-rated occupational physical activity level. A job-exposure matrix (JEM) was also applied to job titles to assess sedentary work. Logistic regression analyses (6 pooled and 12 study-specific) were conducted to estimate associations between both self-reported and JEM-assessed sedentary work and breast cancer risk among premenopausal and postmenopausal women. RESULTS: No association was observed in the 6 pooled analyses, and 10 of the study-specific analyses also showed null results. 2 study-specific analyses provided inconsistent and contradictory results, with 1 showing statistically significant increased risk of breast cancer for self-reported sedentary work among premenopausal women cancer in the Canadian study, and the other a non-significant inverse association between JEM-assessed sedentary work and breast cancer risk among postmenopausal women in the Australian study. CONCLUSIONS: While a suggestion of increased risk was seen for premenopausal women in the Canadian study when using the self-reported measure, overall this pooled study does not provide evidence that sedentary work is associated with breast cancer risk.

RESUMO

BACKGROUND: Evidence shows that prolonged sitting is associated with an increased risk of mortality, independent of physical activity (PA). The aim of the study was to identify correlates of sedentary time (ST) in different age groups and day types (i.e. school-/work day versus non-school-/non-work day). METHODS: The study sample consisted of 1895 Dutch children (4-11 years), 1131 adolescents (12-17 years), 8003 adults (18-64 years) and 1569 elderly (65 years and older) who enrolled in the Dutch continuous national survey 'Injuries and Physical Activity in the Netherlands' between 2006 and 2011. Respondents estimated the number of sitting hours during a regular school-/workday and a regular non-school/non-work day. Multiple linear regression analyses on cross-sectional data were used to identify correlates of ST. RESULTS: Significant positive associations with ST were observed for: higher age (4-to-17-year-olds and elderly), male gender (adults), overweight (children), higher education (adults ≥ 30 years), urban environment (adults), chronic disease (adults ≥ 30 years), sedentary work (adults), not meeting the moderate to vigorous PA (MVPA) guideline (children and adults ≥ 30 years) and not meeting the vigorous PA (VPA) guideline (4-to-17-year-olds). Correlates of ST that significantly differed between day types were working hours and meeting the VPA guideline. More working hours were associated with more ST on school-/work days. In children and adolescents, meeting the VPA guideline was associated with less ST on non-school/non-working days only. CONCLUSIONS: This study provides new insights in the correlates of ST in different age groups and thus possibilities for interventions in these groups. Correlates of ST appear to differ between age groups and to a lesser degree between day types. This implies that interventions to reduce ST should be age specific. Longitudinal studies are needed to draw conclusions on causality of the relationship between identified correlates and ST.

RESUMO

BACKGROUND: Many people work in a sitting position where they have to use their upper extremities and hands. Muscle activity in sitting position is affected by the chair height of, the height of the worktable, and the distance to the working target. OBJECTIVE: The purpose of this study is to investigate differences in muscle activity between men and wemen at different chair heghts and working distances. METHODS: Surface electromyography (EMG) was employed to determine the muscle activity of the upper limbs and the trunk, while an arm-stretching task was performed in a sitting position. RESULTS: Women's muscle activity was higher than that of men in most muscles as the chair height and working distance changed. CONCLUSIONS: As the height of the chair or the working distance was changed, muscle activity was greater in women than in men for most of the muscles analyzed. Under the same conditions, women may feel more muscle fatigue than men, so it is necessary to consider gender in the working environment.

RESUMO

Introduction: Cognitive functions play a crucial role in individual's life since they represent the mental abilities necessary to perform any activity. During working life, having healthy cognitive functioning is essential for the proper performance of work, but it is especially crucial for preserving cognitive abilities and thus ensuring healthy cognitive aging after retirement. The aim of this paper was to systematically review the scientific literature related to the effects of work on cognitive functions to assess which work-related factors most adversely affect them. Method: We queried the PubMed and Scopus electronic databases, in February 2023, according to the PRISMA guidelines (PROSPERO ID number = CRD42023439172), and articles were included if they met all the inclusion criteria and survived a quality assessment. From an initial pool of 61,781 papers, we retained a final sample of 64 articles, which were divided into 5 categories based on work-related factors: shift work (n = 39), sedentary work (n = 7), occupational stress (n = 12), prolonged working hours (n = 3), and expertise (n = 3). Results: The results showed that shift work, occupational stress, and, probably, prolonged working hours have detrimental effects on cognitive functioning; instead, results related to sedentary work and expertise on cognitive functions are inconclusive and extremely miscellaneous. Discussion: Therefore, workplace health and well-being promotion should consider reducing or rescheduling night shift, the creation of less demanding and more resourceful work environments and the use of micro-breaks to preserve workers' cognitive functioning both before and after retirement.

RESUMO

BACKGROUND: Adjustable height sit-stand desks are becoming the norm in many workplaces. It is not known how task type, worker preference, and occupation impact utilization of the adjustable height feature. OBJECTIVE: This survey-based study aimed to determine how task type, preference and occupation affect office workers' sitting and standing behaviors at work. METHODS: Office workers (n = 123) from different occupations completed surveys about actual and preferred positions (sit, stand, either/both) during 39 common tasks from 4 different categories, as well as barriers to use. Each position was analyzed by task type, behavior, and occupation. RESULTS: There were differences between actual and preferred behavior for each position, with participants sitting more and standing less than preferred across all task categories. There were differences between task categories with participants sitting less for generative and routine, and standing more for communication tasks. The highest rates of either/both responses were for routine tasks. Engineers reported the lowest standing rates, and also indicated standing more than preferred. Information Tech and Engineering had the highest either/both responses. Finance reported the highest sitting rates. Personal, task-based and workplace limitations were cited as barriers to preferred use. CONCLUSION: Office workers would prefer to stand more at work. Occupation-specific needs and preferences, as well as types of tasks should be considered when providing workplace standing options.

RESUMO

Background: Physical activity (PA) is beneficial for preventing several conditions associated with underlying chronic inflammation, e. g., cardiovascular disease (CVD) and cancer. While an active lifestyle appears to have anti-inflammatory effects, high levels of occupational PA (OPA) were associated with inflammation and elevated mortality risks. We aimed to summarize the current knowledge (1) on the association between inflammation and OPA and (2) its implications for health and mortality. Methods and results: This mini-review summarized relevant literature published before January 2023 using established scientific databases and sources. For the primary outcome, observational studies (S) reporting immunological effects (O) in subjects (P), with high (I) vs. low OPA (C), were included. For secondary outcomes, i.e., morbidity and mortality associated with inflammatory processes, (systematic) reviews were included. While "active" occupations and "moderate" OPA appear to have beneficial effects, low (particularly sedentary) and "high-intensity" OPA (particularly including heavy lifting tasks) were associated with inflammation and (CVD and cancer-related) mortality; higher leisure-time PA has been almost consistently associated with lower proinflammatory markers and all-cause mortality risks. Workplace interventions appear to counter some of the observed health effects of unfavorable work strain. Conclusion: The few studies addressing OPA "intensity" and inflammatory markers are largely heterogeneous regarding OPA classification and confounder control. Sedentary and "heavy" OPA appear to promote proinflammatory effects. In addition to targeted management of work-related physical strain and hazardous environmental co-factors, occupational health providers should focus on employer-initiated exercise interventions and the promotion of leisure-time PA.

RESUMO

Excessive physical demand at work has traditionally been connected with adverse health outcomes, but excessive sitting is now also being recognised as an occupational hazard and emerging work-related risk. Traditional preventive occupational health and ergonomics programs are useful but limited through reliance on individual behaviour change and time-diversion from productive work. A new 'Goldilocks Work Paradigm' aims to optimise health and productivity by using movements of productive tasks. Using rail driving as a specific case of a highly sedentary and inflexible working environment, we construct a conceptual framework for designing better jobs, arguing that a theoretical amalgamation of the new Goldilocks Work Paradigm with System Thinking, Participatory Ergonomics, and a Risk Management Framework, is needed, for establishing a unified, strategic approach-a 'just right' job design model. We extend this by outlining a practical process of designing better jobs with tools that can be used to achieve it.

RESUMO

The association of physical activity (PA) or sedentary behaviour (SB) with mental health in remotely working software professionals remains unclear. We administered a secondary analysis of physical health variables (PA and SB time during work and non-work days) and mental health variables (stress, anxiety, depression) from a primary study. Ninety-five per cent of the participants (n = 76) did not meet the global PA recommendations. Our study found daily PA time to be negatively associated with stress (ß = -1.57; p = 0.02), anxiety (ß = -1.01; p = 0.04) and depression (ß = -0.68; p = 0.47). Furthermore, the average daily sitting time during the work day was found to be positively associated with stress (ß = 0.28; p = 0.00), anxiety (ß = 0.01; p = 0.04) and depression (ß = -0.68; p = 0.03). Organizational policies should advocate the implementation of PA or SB strategies for improving mental health in remote workers.Trial registrationClinical Trials Registry India identifier CTRI/2021/03/032146.

RESUMO

OBJECTIVES: This systematic review and meta-analysis aimed to assess sedentary work's contribution to breast cancer risk quantitatively using thorough research articles. METHODS: We performed a meta-analysis using a registered protocol in PROSPERO (registration number: CRD42020204629). Literature from PubMed, Embase, and Cochrane involving sedentary work and breast cancer risk was reviewed. We calculated the overall pooled risk ratios (RRs) and 95% CI with a random-effect model from the included studies. Furthermore, we performed stratified analyses by characteristics of studies. RESULTS: Thirty-one studies (13 cohort studies and 18 case-control studies) were included in the analysis. The overall effect of the pooled analysis was an RR of 1.16 (95% CI 1.08-1.23). The results were 1.20 (95% CI 1.10-1.30) and 1.12 (95% CI 1.02-1.23) for cohort and case-control studies. The effect of sedentary work did not seem to be consistently attenuated by controlling body mass index, menopausal status, or experience of hormone replacement therapy. CONCLUSION: The results from this meta-analysis suggest that sedentary behavior within the occupational domain was associated with a 15.5% increased risk of breast cancer. It is essential to reduce the sedentary time spent at work and to secure time for leisure-time physical activity among sedentary workers as a primary preventive measure.

RESUMO

BACKGROUND: Following the declaration of the COVID-19 pandemic by the WHO, many people in the public sector have switched to remote work, including teachers. This could have contributed to the occurrence of back pain in this group. The aim of the study was to assess back pain in a group of teachers before and after the introduction of distance learning due to the COVID-19 pandemic. MATERIAL AND METHODS: The study was based upon an online diagnostic survey and included 361 teachers and university lecturers from 16 provinces of Poland. In order to assess the intensity of pain, a Numerical Rating Scale (NRS) was used. Statistical analysis was performed using IBM SPSS Statistics 26 and Microsoft Excel 2021. The level of statistical significance was adopted on the level p < 0.05. RESULTS: Among the surveyed teachers, the mean degree of declared cervical and lumbar spine pain increased significantly after the COVID-19 pandemic (p < 0.001). The mean value of the declared degree of cervical pain increased from 2.49±2.81 before the pandemic to 5.44±1.83 during the pandemic. Before the pandemic, the mean low back pain intensity was 2.81±2.73 on the NRS, while after the introduction of remote working, it was 5.53±2.20. CONCLUSIONS: There is a relationship between the occurrence of back pain and the change in the nature of work in the group of teachers in connection with the declaration of the COVID-19 pandemic. There has been a statistically significant increase in teachers' back pain intensity since the introduction of distance learning. Depending on the number of hours spent at the computer, the average degree of the declared back pain in the study group increased statistically significantly. There is a need to set the goals of physioprophylaxis and introduce education in the field of ergonomics of computer work in a group of teachers. Med Pr. 2021;72(6):677-84.

RESUMO

This study developed a formula for calculating the predicted VO2 max value using a prototype model of foot-based cardiorespiratory exercise. Forty sedentary workers (20 men and 20 women) were enrolled via consecutive sampling. They underwent direct measurement of VO2 max using spiroergometry as the gold standard; the predicted VO2 max value was calculated using a prototype model of foot-based cardiorespiratory exercise, which was performed on consecutive days. Multivariate linear regression analysis was used to formulate the equation for the predicted VO2 max value by including potential contributing variables: gender, body height, body weight and heart rate. Bland-Altman test was used for assessing the agreement level for the predicted VO2 max value. The equation for the predicted VO2 max value was formulated as 3.2 + 0.15 optimal exercise heart rate -5.5 sexes (0 for men, 1 for women). The agreement level for the formula was acceptable in all measurement result ranges. The formula developed in this study can be used to measure the predicted VO2 max value with an acceptable agreement level.

RESUMO

Although worksite interventions increase physical activity, little is known about their effects on work ability. The objective of this scoping review was to examine the extent, range and nature of interventions to promote work ability by increasing the physical activity or decreasing the sedentary time of sedentary workers in order to identify implications for health promotion at workplaces. We searched Medline, Cochrane Central, and Scopus and identified 29 intervention studies. Using an iterative method, we provided an overview of the study elements and extracted details on study sample, design, intervention content, outcomes, and beneficial effects. Most of the studies (N = 25) were RCTs. Thirteen studies reported beneficial effects on work ability. Tailored and group-based interventions and interventions including environmental actions were often beneficial (9/13). We identified features of feasible and effective interventions for promoting work ability by increasing the physical activity or decreasing the sedentary time of sedentary workers. However, more studies are needed on the sustainability of these effects, and versatile interventions tailored to workers and work demands.

RESUMO

Physical activity (PA) refers to any action produced by skeletal muscle that consumes energy. According to the World Health Organization (WHO), PA is the primary element that can improve health at the community level. Obviously, PA plays an important role in the social, physical, and mental development of men and women, as well as in balancing weight. However, the large-scale negative impacts of physical inactivity on health-related issues are also recognized globally, such as obesity, which is the source of many non-communication diseases (NCDs). In Pakistan alone, 46% of deaths occur due to NCD. The majority of NCD deaths are linked to obesity, and Pakistan is the ninth most obese country in the world. Research on obesity caused by sedentary work in Pakistan is lacking, especially among university employees. To fill this gap, the current study mainly focuses on the rising non-communicable disease (NCD) rates among university employees in Pakistan due to a lack of exercise (obesity, in this case), with the help of a self-designed knowledge, attitude, and practice (KAP) questionnaire. Five universities in the Sindh province of Pakistan were surveyed (n = 276), following the concept of Yin-Yang as a theoretical lens. The results of the current study show that the knowledge, behaviors, and attitudes of university employees have a great influence on their body mass index (BMI). The study shows that Pakistani residents' (especially teaching staff) perceptions and attitudes towards obesity and PA have been instructive, but their practices need to be improved.

RESUMO

There is increasing evidence that subjects who are exposed to long sitting periods suffer from musculoskeletal discomfort and back pain. The underlying mechanism and effective prevention strategies are still largely unknown. In this study, muscle stiffness of the back was measured in 59 office workers who followed their usual desk work regime for 4.5 h in a sitting posture. The sitting period was either followed by an 8-min roller massage intervention or a controlled standing task. Results showed that muscle stiffness increased significantly after the 4.5 h sitting period. When the sitting period was followed by roller massage, the stiffness values dropped slightly below baseline stiffness. In contrast, the stiffness values remained increased when the sitting period was followed by controlled standing. This study indicates that short-duration tissue manipulation can be an effective active break between prolonged sitting periods to prevent musculoskeletal issues, such as musculoskeletal discomfort and back pain.

RESUMO

BACKGROUND: Since desk-dominated work environments facilitate sedentary behavior, office workers sit for 66% of their working days and only 8% succeed in interrupting their prolonged periods of sitting within the first 55 minutes. Yet stretches of long and uninterrupted sitting increase the likelihood of several chronic metabolic and cardiovascular diseases. OBJECTIVE: We therefore developed a computer-based app designed to interrupt periods of prolonged sitting among office employees. METHODS: When developing the intervention, we applied the intervention mapping protocol. This approach for the systematic design of theory and evidence-based behavior change programs consists of 6 steps: creation of a logic model of the problem, creation of a logic model of change, program design, program production, design of an implementation plan, and development of an evaluation plan. RESULTS: Working through all 6 steps has resulted in an individually adaptable intervention to reduce sedentary behavior at work. The intervention, UPcomplish, consists of tailored, half-automatized motivational components delivered by a coach. To register sedentary behavior, the VitaBit (VitaBit Software International BV) toolkit, a wearable accelerometry-based monitoring device, is used. Among others, UPcomplish includes personalized goal setting, tailored suggestions to overcome hurdles, and weekly challenges. The VitaBit toolkit supports the participants to monitor their behavior in relation to self-set goals. CONCLUSIONS: Intervention mapping is a useful protocol not only for the systematic development of a comprehensive intervention to reduce sedentary behavior but also for planning program adherence, program implementation, and program maintenance. It facilitates obtaining the participation of relevant stakeholders at different ecological levels in the development process of the intervention and anticipating facilitators to and barriers of program implementation and maintenance.
