Abstract: BACKGROUND: The bladder compensatory suit (BCS) is important individual protective equipment for pilots’ activities in a high-flying environment. The layout and thermal diffusion ability of the bladder directly affects the thermal comfort of pilots in flight. OBJECTIVE: (1) Established and verified a human–compensatory suit–environment heat transfer model; (2) Used the model to study the human thermal variation of each segment in hot conditions and clothing. METHODS: To verify the two-dimensional heat transfer model, simulated data of body temperature were compared with experimental results under the same conditions (AT: 40/45°C, ordinary clothing). The model could be used …to calculate the temperature variation of each body segment in three environments temperature (28°C, 35°C and 40°C) and three types of clothing (naked, ordinary clothing, BCS). RESULTS: The results showed that: (1) the bladder significantly affected sweating speed and skin temperature, as well as core temperature; (2) the skin temperature of the area covered by the bladder was difficult to reduce by the thermal regulation system. It was because sweat secretion was inhibited, thus, to limit evaporation. CONCLUSIONS: The model could be used as a reference for the thermal protection design of bladder compensatory suit. SUMMARY: The bladder compensatory suit (BCS) is important individual protective equipment for pilots activities in a high-flying environment, and its layout directly affects the thermal comfort. Based on a two-dimensional thermal regulation system model, a body–clothing–environment heat transfer model was established. The model was used to calculate the temperature and sweat variation of each body segment in different environments and clothing. Show more

Abstract: BACKGROUND: Multiple challenges await people with severe physical disability when they are preparing to enter the labour market at the end of the school period. OBJECTIVE: This study aims to better understand the multiple factors that influence the course of disabled youth transitioning into the workforce by gathering perceptions from stakeholders. Methods The study used a qualitative descriptive design with an interpretative description approach to analyze the experiences reported by six school staff, six parents, and three employers. RESULTS: Significant facilitators to the workforce transition were the active involvement of the school’s staff in multiplying outreach …activities between the various external partners. Significant obstacles include the level of help required to complete day-to-day activities at work and student lack of work experience. Government cutbacks were unanimously identified as the prominent obstacle. CONCLUSIONS: The results presented in this study indicate that a successful school to work transition program is dependent on many factors. These factors include the characteristics of the targeted population, the level of involvement from key stakeholders, the willingness of employers to hire this population, as well as program objectives deviating from paid employment. Further development opportunities have proven to be helpful, such as the development of a solid partnership and collaboration between all stakeholders. Show more

Abstract: BACKGROUND: Maintaining adequate working ability of construction workers is of considerable importance for society, as the construction sector is burdened with high prevalence of work-related diseases and health-issues. OBJECTIVE: To determine the number and age of construction workers in Croatia with temporary or permanent work limitation status, as well as to identify the most common health causes of such work limitation. METHODS: A retrospective cross-sectional study was performed using the data from 2534 construction workers, aged between 18 and 65 years, who underwent standardized routine occupational health examinations between 2011 and 2015. Thorough medical history and …medical record reviews, blood and urine analyses, vision parameters and hearing range evaluation, as well as mental health assessment were conducted on every study participant. RESULTS: A total of 210 construction workers (8.29%) received occupational/work limitation status (either temporary or permanent). Four main categories of work limitation were high blood pressure, disorders of the liver and digestive system, hearing loss and amblyopia, comprising 61.69% of all diagnoses. A total of 37.62% of workers with work limitation status had two or more different diagnoses (i.e. co-morbid conditions). Those with work limitation (either temporary or long-term) were significantly older than those fit enough to work (p -value <0.00001). CONCLUSIONS: This type of organized screening represents a significant preventative effort in the construction industry, as workers may become more cognizant of the conditions that may affect their work ability.

Abstract: BACKGROUND: Strategies to increase non-exercise activity thermogenesis (NEAT) through promotion of movement and energy expenditure at desk stations are needed to help overcome ill effects of prolonged sitting. OBJECTIVE: Examine the metabolic rate during three stages of a workstation: sitting, standing, and use of a device (HOVR® ) that promotes leg movement while seated. METHODS: Participants (n  = 16; mean ±standard deviation: age 26.1±6.0 years; BMI 24.7±4.3 kg/m2 ) were tested for VO2 and VCO2 for 15 min at each stage in this order: sitting only, sitting using the HOVR, and standing. Participants performed the same desk …work to keep fine-motor activity consistent for the stages. Data collected during the final 5 min of a stage were averaged and analyzed as steady-state data. To evaluate the effect of each stage on cognitive function, the Stroop word-color test was administered after metabolic assessment as the stage continued. One-way ANOVA with repeated measures was used to compare stages for VO2 (L/min), metabolic equivalents (METs), respiratory exchange ratio (RER), and heart rate (p  < 0.05). RESULTS: The ANOVA revealed significant differences between the mean values for each stage for each dependent variable (p  < 0.05). Post hoc tests indicated VO2 differed for each stage (mean±SD in mL/kg/min: sitting, 4.13±0.56; sitting with HOVR, 4.82±0.74; standing, 4.50±0.53; p  < 0.05). METs followed a similar pattern (sitting, 1.19±0.16; sitting with HOVR, 1.39±0.20; standing, 1.29±0.16; p  < 0.05). An increase in Stroop Test scores was found as the stages progressed (p  < 0.05). CONCLUSION: Modest movement while seated, i.e., use of HOVR, elevated metabolic rate by 17.6% compared to sitting and by 7% compared to standing and might be a reasonable strategy to help elevate NEAT during the workday.

Abstract: BACKGROUND: Pressure on the shoulder can be a major limiting factor to backpack use and poor design can lead to pain and injury. OBJECTIVE: To evaluate the effect of shoulder strap width and load placement in a backpack on the shoulder and axilla. METHODS: A manikin fitted with a backpack load of 20 kg mass and four different width straps (5, 6, 7, and 8 cm) was used. The load was placed high or low. Interface pressure sensors were placed over the shoulder and chest wall at the axilla. RESULTS: A significant interaction was observed between …shoulder strap width and load placement. The positive effect of wide straps on shoulder pressure is greater with high load placement and the benefit of wide straps on axillary pressure is improved with low load placement. Interface pressure decreased significantly from narrow to wide straps. A large difference was noted between interface pressure on high and low load placement with narrow straps; however, as shoulder strap width increased, the difference between the two load placements decreased. CONCLUSION: The least amount of interface pressure was observed with 8 cm shoulder straps and high load placement. These findings should influence design and use of backpacks. Show more

Abstract: BACKGROUND: Notwithstanding efforts by vocational services to assist Australians with mental illness into employment many of these consumers remain unemployed. OBJECTIVE: To inform policymakers and practitioners of a disability employment services reform framework that endeavours to help more consumers who are experiencing mental illness to attain and retain employment. METHODS: Thematic analysis was directed to summarize results obtained from a narrative literature review of disability employment service reforms utilising Scopus, Medline and Pubmed databases and including articles published between 2000 and 2016. RESULTS: Research results reveal a preparative framework covering three levels of disability …employment services reform for consumers with mental illness. CONCLUSION: This research makes important theoretical contributions across three areas. First this study reveals individualised, integrated and outcome-oriented services as dimensions of disability employment services reform that warrant greater government investment, practitioner focus and consumer involvement. Second recognising that none of these service reforms are immune from challenges which may hinder their effectiveness, future research is needed to identify evidence-based mitigation measures. Finally with individualised services positioned at the nucleus of the reform framework, integrated services and outcome-oriented reforms should be operationalised in ways that remain sensitive to the principle of strength-based support.

Abstract: BACKGROUND: Milling machine operators perform physically demanding tasks that can lead to work related musculoskeletal disorders (WRMSDs), but literature on WRMSDs among milling machine operators is scarce. Knowledge of prevalence and risk factors of WRMSDs can be an appropriate base for planning and implementing ergonomics intervention programs in the workplace. OBJECTIVE: This study aimed to determine the prevalence, pattern and associated factors of WRMSDs among commercial milling machine operators in Enugu, Nigeria. METHODS: This cross-sectional survey involved 148 commercial milling machine operators (74 hand-operated milling machine operators (HOMMO) and 74 electrically-operated milling machine operators (EOMMO)), within …the age range of 18–65 years, who were conveniently selected from four markets in Enugu, Nigeria. A standard Nordic questionnaire was used to assess the prevalence of WRMSDs among the participants. Data were summarized using descriptive statistics. RESULTS: There was a significant difference (p  = 0.001) related to prevalence of WRMSDs between HOMMOs (77%) and EOMMOs (50%). All body parts were affected in both groups and shoulders (85.1%) and lower back (46%) had the highest percentage of prevalence. Working in awkward and same postures, working with injury, poor workplace design, repetition of tasks, vibratory working equipments, reduced rest, high job demand and heavy lifting were significantly associated with the prevalence of WRMSDs. CONCLUSIONS: WRMSDs are prevalent among commercial milling machine operators with higher occurrence in HOMMOs. Ergonomic interventions, including the re-design of milling machines and appropriate work posture education of machine operators are recommended in the milling industry. Show more

Abstract: BACKGROUND: Return to work is an important aspect for cardiac rehabilitation following a major cardiac event. OBJECTIVE: The aim was to understand the local prevalence and factors associated with returning to work in Malaysia after a cardiac event. METHODS: A cross sectional design was used. All patients attending the cardiac rehabilitation program after major cardiac event during an 11-months period (2011-2012) were included. Data relating to socio-demographic, work-related, risk factors and acute myocardial infarction were collected. The SF-36 questionnaire was used to assess quality of life. Regression analysis was used to determine the predicting factors to …return to work. RESULTS: A total of 398 files were screened, 112 respondents agreed to participate giving a response rate of 47.3%. The prevalence of returned to work (RTW) was 66.1% [95% CI: 57.2–75.0]. Factors associated with work resumption were age (Adj. OR: 0.92 (95% CI: 0.84–0.99), diabetes mellitus (Adj. OR: 3.70, 95% CI: 1.35–10.12), Mental Component Summary (MCS) score (Adj. OR: 1.05 (95% CI: 1.01–1.09) and baseline angiography findings. Patients with single vessel and two vessel disease were 8.9 times and 3.78 times more likely to return to work compared to those with 3 vessels (Adj. OR: 8.90 (95% CI: 2.29–34.64) and Adj. OR: 3.78, (95% CI: 1.12, 12.74). CONCLUSIONS: We proposed a cardiac rehabilitation program to emphasize mental health as it may improve successful return to work after cardiac event. Show more

Abstract: BACKGROUND: A high prevalence of musculoskeletal disorders and abnormal alignments of the lower extremities (LE) was found for rice farmers. It is important to investigate demographic and work-related risk factors associated with LE pain prior to developing intervention strategies addressing the problematic factors of the highest-risk task. OBJECTIVE: To identify factors associated with LE pain in rice farmers for every stage of the cultivation process. METHODS: Thirty experienced farmers (age of 45.9±6.21 (mean±SD)) rated LE pain experienced before and after each cultivation stage using the Standardized Nordic Questionnaire. Risk factors of pain were characterized based on …expert risk assessment of tasks due to force, posture and motion, in addition to a conventional survey of demographic and other work-related information. RESULTS: Ergonomic risk factors were found to be the strongest predictors of knee and foot pain perception, which induced a substantial increase of pain perception (up to 4.6 times) with varying extent for individual cultivation stages. The highest risk and pain perception was found during the planting performance. Age exhibited significantly positive association with foot pain during planting and harvesting. However, more experienced farmers perceived less foot pain, presumably by developing effective movement strategies. CONCLUSIONS: The findings suggest that the planting process should be subject of further intervention development, especially for older farmers, with focus on reducing force, awkward posture and repetitive movement to minimize risk of LE pain.

Abstract: BACKGROUND: Insurance workers and physiotherapists are important stakeholders in the rehabilitation of workers with an injury and subsequent musculoskeletal pain. Understanding perceptions of roles may facilitate communication between these stakeholders. OBJECTIVE: Increase knowledge around, (i) the self-perception of and (ii) the external perception of the insurance workers and physiotherapists roles in the management of a worker with an injury in an Australian workers’ compensation environment. METHODS: A cross-sectional study assessed the perceptions of insurance workers and physiotherapists related to the roles of these two professions in managing a worker with an injury via questionnaire. Respondents were …also asked about potential communication barriers. RESULTS: Insurance workers (n  = 48) and physiotherapists (n  = 80) reported contrasting role perceptions, with their perception of the other profession leaning towards negative attributes. There was greater alignment of their beliefs of roles in the ‘ideal’ situation. The perception of barriers to communication also differed between the two professions. Effective and efficient communication was identified as a central component of mismatched role perceptions between stakeholders, but recognised as a critical attribute of ‘ideal’ stakeholder roles. CONCLUSION: Insurance workers and physiotherapists self-perception of their roles differs from external perceptions. This information highlights the importance of a shared understanding of stakeholder roles in the management of a worker with an injury. Show more

Abstract: BACKGROUND: Although the relationship between work–life balance (WLB) and health is well known, it has been poorly studied in Korea. OBJECTIVE: This study investigated factors related to WLB for Korean workers, including working time features and the relationships between WLB and health outcomes. METHODS: Data were obtained from the third Korean Working Conditions Survey, which examined a representative working population. This study investigated general characteristics, working time characteristics, work related health, and WLB. A multivariate logistic regression was used to test the associations between WLB and health outcome variables, including general health status, mental health, work-related …risks to health and safety, sickness absenteeism, presenteeism, musculoskeletal disease, headache/eyestrain, and fatigue. RESULTS: General characteristics including gender, age, working sector, occupation, and employment type were found to be related to WLB. Moreover, working time characteristics were found to be strongly related to WLB. In addition, WLB was significantly related to various health outcomes. CONCLUSIONS: Our findings indicate that WLB is strongly related to health outcomes among Korean workers. The results suggest that there is a need for interventions that focus on implementing working time strategies for better health. Show more

Abstract: BACKGROUND: Working in a closed environment for more than 7-8 hours can affect both psychological and physical health among kindergarten workers. OBJECTIVE: To determine the prevalence of musculoskeletal disorders (MSD) and depression as well as the correlation between them, if any, among kindergarten workers. METHODS: In a cross-sectional observation, one hundred and five healthy female staff members (age: 34.27±7.01 year, working duration: 7.42±0.81 hr/d, BMI: 24.50±2.61 kg/m2 (mean±SD)), who have had at least one year of working experience, were selected randomly from 10 kindergartens. The subjects completed both the Cornell musculoskeletal and Patient Health (PHQ-9) questionnaires to …enable the assessments of MSD and depression scores accordingly. The correlation between both questionnaires was then measured to find any links. To assess the reliability of Farsi-language versions of the Cornell questionnaire and PHQ-9, the Inter-class Correlation Co-efficient (ICC) was measured through test-retest with 1-week delay and the prevalence of MSD and depression were subsequently assessed as well. RESULTS: The Inter-class Correlation Co-efficient (ICC) illustrated that the Farsi version of MSD instruments showed high levels of repeatability. The ICC coefficient was (0.932–0.987, p  < 0.001) for the Cornell questionnaire and the Cronbach alpha for PHQ-9 questionnaire was 0.861. The highest severity of pain was related to lower back (30.5%), and after it, neck (27.6%), right shoulder (27.6%) and left shoulder (25.7%) pain, respectively. The results of PHQ-9 questionnaire indicated that 41.9% (n  = 44) of subjects had a severe depression. There was a significant (r  = 0.338, p  < 0.01) relation between depression and MSD. CONCLUSIONS: Prevalence of depression and severity of physical pain was an issue among staff in kindergartens. More study will be needed to define all aspects of this issue. Show more

Abstract: BACKGROUND: The Redesigning Daily Occupations (ReDO™) work rehabilitation method has been found effective, compared with care as usual (CAU), for women with stress-related disorders. OBJECTIVE: To conduct a long-term follow-up of former ReDO™ and CAU participants with respect to sick leave, well-being and everyday occupations 3-4 years after completed work rehabilitation. METHODS: Forty-two women in each group participated. An index day was decided to estimate sick-leave rate, retrieved from register data. Fifty-five women also participated in a telephone interview addressing well-being, everyday occupations and life events. RESULTS: Both groups had reduced their sick-leave rate …further, but no difference between the groups was established. The ReDO™ women perceived a better balance in the work domain of everyday occupations, whereas the CAU group reported more over-occupation. No differences were found on well-being. The groups had experienced similar important life events, affecting the women’s work and private lives. Previous stress and anxiety predicted sick leave at the long-term follow-up. CONCLUSIONS: Although the ReDO™ intervention had speeded up return to work in the immediate follow-up perspective, the CAU had caught up in the longer term. Still, the ReDO™ women exhibited better balance in the work domain. Show more

Abstract: BACKGROUND: Stigma and disclosure are important work-related issues for people living with HIV (PLWH). To gain better understanding and improve the position of PLWH in the labor market, further insight in these issues is needed. OBJECTIVE: This study reviews the scientific evidence related to work-related stigma and disclosure. METHODS: A sensitive literature search was performed in the databases of Medline, Embase, Cochrane Library, Cinahl and Psychinfo for articles published between 1996 and 2016. All studies on PLWH in western countries and investigating disclosure or stigma in relation to work were included. RESULTS: Of the …866 identified studies, 19 met the inclusion criteria: 4 addressed both disclosure and stigma (2 quantitative), 9 addressed only disclosure (4 quantitative) and 7 studies addressed only stigma (4 quantitative). CONCLUSION: This review provides a unique overview of the research on work-related disclosure and stigma, which will enable health care providers to support PWLH to make well-considered decisions. However, the available literature was heterogeneous and in most studies the topics of our interest were secondary outcomes and provided only basic insight. Show more

Abstract: BACKGROUND: In developing countries such as Mexico, the effects of burnout syndrome (BS) are observed in manufacturing industries. However, the relationships among BS, Job Content (JC ), and Musculoskeletal Complaints (MC ) are scarcely studied within the manufacturing sector, even though senior and middle managers are exposed to highly demanding and mentally exhausting situations. OBJECTIVES: The objective of this paper is to determine the relationships among the three BS dimensions, MC , and JC among middle and senior managers of the manufacturing industry in Ciudad Juárez, Mexico. METHODS: The Maslach Burnout Inventory-General Survey …(MBI-GS), the Job Content Questionnaire (JCQ), and the Body Map assessment were administered as data collection instruments. The sample included 361 participants from six industries located in Ciudad Juárez, Mexico. Also, we proposed structural equations models (SEM) to establish the relationships among variables. RESULTS: The questionnaires and the model showed acceptable reliability and quality indices. Emotional exhaustion was the most relevant latent variable, having significant effects on MC and on professional efficacy , and significantly contributing to increasing levels of cynicism . On the other hand, the variable social support showed a negative direct impact on Job Demands and Emotional Exhaustion . CONCLUSIONS: Actions to reduce emotional exhaustion at work include providing a positive and suitable work environment through social support . These strategies help prevent MC and improve professional efficacy , life quality at work, and productivity. Show more

Abstract: BACKGROUND: Depletion of groundwater has increased the depth of bore wells drilled to meet water requirements. Water from these bore wells are accessed by operating submersible pumps with multi-stages. The number of stages of submersible pump directly depends upon the depth of bore well. Health-related risk such as Musculoskeletal Disorders (MSDs) arises during the manual assembly of these pumps in an awkward posture. OBJECTIVE: The objective of this paper is to eliminate or reduce risk in the manual assembly of submersible pumps using virtual postural analysis. Secondary objective is to redesign the existing workstation incorporating ergonomic interventions. …METHODS: It reports a case study in which postural analysis is carried out with the help of Rapid Upper Limb Assessment (RULA) method. RESULTS: It is observed that inserting the stage casing weighing around 1.5 Kg through top end of the shaft is the awkward working posture involving a flexion of the arm about 152°. RULA score (7) indicate a high level of risk exists in the workstation, calling for investigate and change the working posture immediately. In order to reduce this risk, a redesigned workstation has been proposed. CONCLUSION: This study results help in minimizing the awkward postures, thereby reducing the health-related risk. This will also increase the efficiency of the worker and his productivity. Show more

Abstract: BACKGROUND: Knowing the high and low peaks in comfort during a flight could be useful in prioritizing aircraft interior improvements. OBJECTIVE: The first objective of this study was to identify whether there are differences in comfort experiences during different phases of a flight. The second objective of this study was to identify similarities between recalled and real time reported comfort experiences. METHODS: 149 participants were asked to rate the comfort in the different phases of their last flight on a scale from 1–10. Additionally, a combination of a self-reporting design probe and generative interview was used …to investigate the appraisal patterns of emotions in nine passengers. RESULTS: The 149 subjects reported the highest comfort after take-off and arriving at the destination, the lowest while stowing the luggage and during the cruise flight. The qualitative long haul inflight study showed after take-off and while arriving at the destination the most positive emotions and during the cruise flight there is a negative experience phase. CONCLUSIONS: Suggestions are given to improve the cruise flight phase, by for example stimulation of movement or better service. Show more
