Abstract: BACKGROUND: The COVID-19 global pandemic brought several challenges to occupational safety and health practice. One of these is the need to (re)assess the occupational risks, particularly, biological risks. OBJECTIVE: The purpose of this work is to promote guidance to occupational safety and health practitioners when conducting a biological risk assessment in this context. METHODS: The main steps of the biological risk assessment are explained with some inputs regarding the novelty posed by SARS-CoV-2 and an example of a qualitative risk assessment method is presented. Also, its application to two different activities was exemplified. RESULTS: …In both cases, the assessment considered that vulnerable workers were working from home or in medical leave. The results showed low or medium risk level for the assessed tasks. For medium risk level, additional controls are advised, such maintain social distancing, sanitize instruments/equipment before use, use proper and well-maintained PPE (when applicable), and promote awareness sessions to spread good practices at work. Employers must be aware of their obligations regarding biological risk assessment and OSH practitioners must be prepared to screen and link the abundance of scientific evidence generated following the outbreak, with the technical practice. CONCLUSIONS: This paper could be an important contribution to OSH practice since it highlights the need to (re)assess occupational risks, especially biological risk, to ensure a safe return to work, providing technical guidance.

Abstract: BACKGROUND: Burnout and professional satisfaction is an often an overlooked component for healthcare outcomes; the COVID-19 pandemic represents an unprecedented stressor that could contribute to higher levels of burnout. OBJECTIVES: Our primary objective was to evaluate the association of a battery of fulfillment, job satisfaction change, COVID-19 concerns, and coping measures. Our secondary objective was to determine whether the fulfillment and coping measures differed by gender and by experience levels among a battery of physician specialties. METHODS: The study was a purposive sample of convenience. Study participants included all trainees and attending orthopedic surgeons from our …academic institution; all participants were invited to complete a survey built around a validated measure of professional fulfillment aimed at assessing response to acute change and stressors. We performed univariate statistics and a matrix correlational analysis to correlate different survey domains with variables of interest. RESULTS: The survey was sent electronically to 138 individuals; 63 surveys were completed (response rate = 45.7%). Twenty-seven (42.8%) individuals met the threshold criteria for fulfillment whereas 10 (15.9%) met the threshold for burnout. We found that surgeon perspectives on COVID-19 were not associated with burnout or professional fulfillment. Burnout was inversely associated with professional fulfillment (R  = –0.35). Support seeking was noted to be correlated with professional fulfillment (R  = 0.37). CONCLUSIONS: Stressors related to COVID-19 pandemic were not correlated with physician burnout and fulfillment. This held true even when stratifying by gender and by attending vs. trainee. Continued efforts should be implemented to protect against physician burnout and ensure professional fulfillment for Orthopedic surgeons. Show more

Abstract: BACKGROUND: The COVID-19 pandemic has put health systems under unprecedented pressure, challenging their workforce, especially nurses. OBJECTIVE: The current paper presented a review of the early literature concerning emerging nursing challenges during the early stages of the COVID-19 pandemic. METHODS: A systematic search of the published literature between January and May 2020 was carried out in Medline, Science Direct, and Google Scholar to identify relevant quantitative and qualitative studies. RESULTS: Twenty-two original articles were retrieved, the majority of which were survey studies from China. Synthesis of the evidence resulted in four overarching themes including …“being physically and mentally drained in the face of fear and uncertainty,” “shortage of personal protective equipment and usability issues,” “psychosomatic disturbances among nurses,” and “moderators to mitigate nurses’ challenges.” CONCLUSIONS: Providing care for demanding COVID-19 patients, nurses experienced a gruelling situation, during which a significant amount of psychological and physical distress was inflicted to them. However, receiving proper support from their organization and society could improve the condition substantially. Further research is required to explore the impact of the COVID-19 pandemic on nurses, especially from Western countries. Show more

Abstract: BACKGROUND: Nurses experience loneliness, anxiety, fear, fatigue, sleep disorders, and other physical and mental health problems due to their close contact with patients in cases of epidemic diseases. Among nurses in Turkey, we want to explore how anxiety, psychological health, and social isolation affect nurses’ quality of life. OBJECTIVES: This study aimed to investigate the effects of the COVID-19 pandemic on the quality of life (COVID-19 EQLS), State-Trait Anxiety Inventory (STAI-1 and STAI-2), psychological health, and social isolation among nurses. It also aimed to identify whether the influence of trait anxiety, psychological health, and social isolation are stronger …than the direct influence of state anxiety on nurses’ quality of life during the pandemic. METHODS: A cross-sectional study design and STROBE guidelines were implemented. In this study, 638 nurses in Turkey were included using simple random sampling. The participants completed the STAI-1 and STAI-2 and COVID-19 EQLS online-form. The parallel-serial mediation model was used to examine the relationships between the determined variables. RESULTS: Psychological health, psychological effects of social isolation, and trait anxiety fully mediated the relationship between state anxiety and quality of life of nurses. The total indirect effect of the confidence interval of bootstrapping was statistically different from zero. CONCLUSIONS: Trait anxiety, psychological health, and social isolation were the main factors with statistically significant indirect effects on the quality of life of Turkish nurses in this study.

Abstract: BACKGROUND: COVID-19 increased psychological and physical complaints, including anxiety, depression, and pain. OBJECTIVE: We aimed to examine anxiety, depression, and musculoskeletal complaints that may occur in healthcare workers during the COVID-19 pandemic. METHODS: Data were cross-sectional, collected by the online questionnaire method consisted of demographic questions, Generalized Anxiety Disorder (GAD-7), Patient Health Questionnaire (PHQ-9), Nordic Musculoskeletal System Query (NMQ), and Visual Analogue Scale (VAS). RESULTS: Among the groups, the number of doctors in the frontline group, the fear of being infected, the number of tests performed, and personal protective equipment were higher than the …second-line group (p  < 0.05). It was found that 73.4% of the participants had anxiety, 83.5% had depression, and 94.9% had musculoskeletal pain. It was observed that there was no statistically significant difference between the applied scale scores between the groups (p  > 0.05). About musculoskeletal system complaints of the participants, neck pain presence was determined as 73.4% in the last 12 months, and upper back pain was the highest with 61.4% in the last week. Neck (p  < 0.005) and upper back pain (p  = 0.04) parameters in the last seven days of the NMQ scale applied to the participants were found to be statistically significantly higher in the contact group. CONCLUSIONS: Anxiety, depression, and musculoskeletal pain of healthcare workers were found to be high. While neck and back pain was the most common in musculoskeletal complaints, it was found that these pains were higher in the frontline group. In this regard, healthcare professionals can be given psychological support and exercise training. Show more

Abstract: BACKGROUND: Robots are gaining attention as a potential solution to aging. OBJECTIVE: The purpose of this study is to explore the attitude of robot assistance in Activities of Daily Living (ADLs) among elderly people living independently. METHODS: The one-on-one interview, buddy robot video and questionnaire survey were used to analyze mean, median, range, and the test results of non-parametric statistical methods such as Wilcoxon sign-rank test statistic and one-sample Wilcoxon sign-rank test statistic, so as to explore the attitude of the elderly living independently towards robot-assisted ADLs and the acceptance of the use of robots in …32 ADLs. RESULTS: The results showed that there were significant differences in the attitudes, usability and ease of use of elderly people towards robot assistance before and after watching the Buddy Robot video and they had a more positive attitude after watching the video. According to the results, the elderly was more receptive to the use of robots in activities such as “reminding to carry objects” and “reminding to take medicine”, while they were less receptive to the use of robots in the group or private activities such as “playing mahjong” and “taking a bath”. CONCLUSIONS: The results showed that the elderly had a positive attitude towards the use of robot-assisted ADLs, and there were differences in the acceptance of robot-assisted ADLs. The results are helpful to understand the assistance needs and attitudes of the elderly, and provide a reference for the design of assistive robots that meet user needs, and ultimately improve the ability of the elderly to live independently at home.

Abstract: BACKGROUND: Cadmium (Cd) exposure in environmental and occupational settings is a major public health concern. Cd exposure is associated with the production of free radicle and reactive oxygen species. The aim of the present study is to evaluate the effect of occupational exposure to Cd on oxidative stress and pro-inflammatory biomarkers in the workers. METHODS: 100 occupationally exposed individuals working in the metal handicraft industry and welding industry were recruited from the industrial area of Jodhpur, Rajasthan. Blood Cd levels were estimated using atomic absorption spectroscopy. Serum Total Antioxidant Capacity (TAC), Catalase (CAT), Superoxide Dismutase (SOD), and Malondialdehyde …(MDA) levels were measured by colorimetric method to assess oxidative status and serum IL-6 and TNF-α were measured by ELISA to assess inflammatory status. RESULTS: The median Cd levels in the study population was 2.40μ g/L, with welders having significantly higher Cd levels than metal handicraft workers. Among the oxidative stress markers, TAC and CAT were significantly lower, while MDA was significantly higher in subjects with high Cd levels. The Cd levels showed a significant negative and positive correlation with TAC and MDA, respectively. IL- 6 and TNF-α did not show a significant difference between the study groups, but both had an inverse correlation with antioxidant enzymes. CONCLUSION: Occupational exposure to even low levels of Cd may result in oxidative stress in workers primarily via decrease in antioxidant enzymes and increasing lipid peroxidation. Increased oxidative stress in turn may result in immune cell activation which may result in increased concentration of pro-inflammatory cytokine in the exposed workers. Show more

Abstract: BACKGROUND: Implementing workplace accommodations is an effective means of retaining employees with mental health conditions. However, the process is poorly understood and poorly documented. OBJECTIVE: The purpose of this research is to explore the interactive process of negotiating workplace accommodations from the perspective of employees with mental health conditions and workplace stakeholders. METHODS: We interviewed employees across Canada who self-identified as having a mental health condition requiring accommodations, and six stakeholders at various workplaces across Canada who are involved in providing accommodations. Data were analyzed using a qualitative descriptive approach to identify key …themes. RESULTS: The findings highlight that the process of negotiating accommodations is non-linear, interactive, and political. The process is shaped by organizational and political factors and collaboration between stakeholders. CONCLUSIONS: The negotiation process is a combination of social, relational and political factors. Clear and accessible accommodation policies, workplace awareness and specific workplace training on how to implement accommodations are needed to optimize the accommodation process for all involved.

Abstract: BACKGROUND: The prevalence of working-aged stroke survivors is increasing yearly. Stroke is an expensive disease, causing financial burden to the government, the family and caregivers of the patient, thus making it imperative for working-aged stroke survivors to work to remain financially independent. Survivors’ need to work necessitates occupational therapists to shift their focus from basic activities of daily living, to rehabilitating work. OBJECTIVES: This study aimed to determine the perceptions of occupational therapists working with younger stroke survivors in public hospitals and clinics in Gauteng South Africa, about rehabilitating working-aged stroke survivors’ work ability. METHODS: …Ethical clearance was obtained. A qualitative research design was used to obtain narrative, descriptive data from six focus groups. Therapists from public healthcare settings, who had more than six months’ experience and had worked in neurological rehabilitation within the six months preceding the focus group, were invited to participate. Focus groups were audio recorded and transcribed. Inductive content analysis was used to identify themes and categories. RESULTS: Few participants are involved in rehabilitating younger stroke survivors’ work ability or facilitating return to work (RTW). The study identified perceived barriers and enablers to rendering OT services that meet working-aged stroke survivors’ needs. CONCLUSIONS: Despite enabling employment equity laws in South Africa, OTs working in the public sector appear to experience a sense of futility when trying to rehabilitate young stoke survivors to RTW. Fragmentation of the public sector and limited resources impede successful RTW for working-aged stroke survivors. Survivors’ employment status and motivation to RTW facilitated rehabilitating work ability. Show more

Abstract: BACKGROUND: Evidence for the adoption and acceptance of assistive devices for ladder lifting tasks by workers is scarce. OBJECTIVE: This study aims to investigate the technology acceptance and usability of a powered and automated cargo management system (RazerLift® ) used by workers who need to lift ladders as part of their daily duties, as compared to mechanical cargo management systems (traditional). METHODS: We used a one-way repeated measures design in this study. Our primary outcome variable was a usability performance measurement measured as time (in seconds) for unloading and loading ladders using both systems. Our secondary …outcome was technology acceptance, measured using questionnaires with a 5-point Likert scale: “strongly disagree (1)” to “strongly agree (5)”. RESULTS: The participants conducted the combined unloading and loading time using the powered and automated system (RazerLift® ) 20.85 seconds faster than the traditional system (p -value = 0.000, t-value (df) = –5.730 (6), d  = 2.713). Overall, the RazerLift® system (mean = 44.28, SD 5.58) had a higher technology acceptance compared to the traditional system (mean = 30.00, SD 7.91), (p  = 0.041, t-value (df) = 6.589 (6), d  = 4.60). CONCLUSIONS: The RazerLift® was more time efficient compared with the traditional system, and (2) the RazerLift® was superior in terms of technology acceptance compared to the traditional system.

Abstract: BACKGROUND: Almost 25%of workers in the European Union suffer from back pain, and 23%complain of muscle pain. Sixty-two percent of workers carry out repetitive operations with their hands or arms, 46%work in painful or tired positions and 35%carry or handle loads. OBJECTIVE: This study aimed to translate, culturally adapt and validate the Italian version of the Cornell Musculoskeletal Discomfort Questionnaire (CMDQ-I). METHODS: Translation and cultural adaptation procedures followed international guidelines. Participants were recruited from among the personnel components of the Italian Air Force, who were between 18 and 65 years old. Cronbach’s alpha and the intraclass …correlation coefficient (ICC) were calculated to assess internal consistency and stability, respectively. The CDMQ-I was administered together with the Visual Analogic Scale (VAS), and the validity was evaluated using Pearson’s correlation coefficient. RESULTS: All CDMQ-I items were either identical or similar in meaning to the original version’s items. The scale was administered twice with a retest after seven to 10 days to 66 participants. Cronbach’s alpha was higher than 0.761, and the ICC ranged between 0.737 and 0.952. Pearson’s correlation coefficient showed positive and significant correlations (p  > 0.01). CONCLUSIONS: The study produced an Italian version of the CMDQ with good reliability and validity. This scale is a useful tool to investigate the frequency and intensity of musculoskeletal disorders in various categories of workers. Show more

Abstract: BACKGROUND: Neck discomfort and pronounced neck flexion have been associated with smartphone use. OBJECTIVE: Eye glasses with a 90 deg prism in each lens were investigated as a potential intervention to reduce awkward head and neck postures during activities involving viewing the device. METHODS: Sixteen smartphone users with neck pain and 9 asymptomatic users performed a texting task on a smartphone with and without the prism glasses, in sitting and standing postures in a laboratory setting. RESULTS: Cervical erector spinae and upper trapezius muscle activity, head posture and motion, performance, …discomfort and other subjective perceptions were assessed. Prism glasses reduced neck extensor muscle activity, neck flexion, and head tilt compared to the direct view. In the symptomatic group, the intervention produced less neck and shoulder discomfort compared to the direct view. CONCLUSIONS: This intervention could offer an alternative way of interacting with a smartphone while texting in stationary postures, by reducing exposure to pronounced flexed neck and head posture commonly seen in users, and thereby could reduce neck discomfort associated with smartphone use.

Abstract: BACKGROUND: Spinal pain is one of the leading causes of morbidity globally. There is an increase in the number of children and adolescents who experience spinal pain and the lifetime prevalence of adolescent spinal pain varies between countries. In Africa, one in two adolescents experiences spinal pain and the prevalence is increasing. OBJECTIVE: This study reports on the knowledge and perspectives of school-attending children, adolescents, teachers, and parents/guardians regarding spinal health. METHODS: We conducted a descriptive qualitative case study with an interpretative and phenomenological approach. Data coding, management and analysis was done using ATLAS.ti computer software. …RESULTS: Ninety-three participants (66 women and 27 men) were enrolled in the study. The barriers associated with students’ spinal health were multifactorial, including low levels of physical activity, dangerous gameplay, sports risks, poor ergonomics, school bags, insufficient knowledge, and pregnancy risks. Participants proposed strategies to improve spinal health including the provision of students’ lockers, advice on appropriate school bag types, embedding spinal education in the curriculum, general advocacy for spinal health, and integration of technology in teaching and learning. CONCLUSION: There is a need for further engagement on school-based spinal health promotion programs that consider local socio-economic, educational, and cultural factors. Show more

Abstract: BACKGROUND: Switzerland’s Ordinance on Maternity Protection at Work (OProMa) requires that companies take the necessary measures to ensure that pregnant employees can continue working without danger. OBJECTIVE: To investigate the extent of compliance with OProMa within companies in French-speaking Switzerland as well as factors which facilitate and obstruct the ordinance’s implementation. METHODS: A stratified random telephone survey of 202 companies from the healthcare and food industry was conducted. Descriptive and correlational statistics were calculated. Responses to open questions were analysed thematically. RESULTS: Only a minority of companies performed risk analyses or adapted employees’ workstations, …as per the legislation. OProMa was implemented more effectively in larger companies than smaller ones, in public rather than private ones, in the healthcare sector rather than the food industry, and when the person responsible for the wellbeing of pregnant employees within the company had undergone specific training on the subject. Data extrapolation suggested that only 2% of pregnant employees in French-speaking Switzerland’s food industry and 12% in its healthcare sector are properly protected according to OProMa’s provisions. CONCLUSIONS: Maternity protection in French-speaking Switzerland’s companies urgently requires improvement. In addition to the apparent need for stronger incentives and for monitoring of companies, our findings indicate a need to provide them with resources to meet OProMa’s provisions. Show more

Abstract: BACKGROUND: Sleep apnoea is a diagnosed condition in which appurtenances interrupt breathing whilst sleeping. The consequence of obstructive sleep apnoea (OSA) includes road traffic accidents due to drowsiness, systemic hypertension, heart disease, diabetes mellitus and neurocognitive disorders. This condition extends the duration of recovery phase after traumatic brain injury. OBJECTIVE: This study was intended to assess the knowledge and attitude towards OSA and compare it among dental and medical undergraduate students of University Sains Malaysia (USM). METHODS: In this study, a total of 216 clinical undergraduate students (36 from each year; 108 from medical and 108 …from dental school) of University Sains Malaysia (USM) Health campus were recruited for the study by non-probability stratified random sampling method. Total study period was October 2017 to October 2018. A self-administered questionnaire was used to assess the sociodemographic status and OSAKA questionnaire was used to assess knowledge and attitude regarding sleep apnoea of the respondents. Descriptive analysis was carried out to assess the knowledge and attitude of OSA amongst dental and medical undergraduate students of USM. The Mann–Whitney U test was carried out to compare the knowledge and attitude of OSA amongst dental and medical undergraduate students of USM. RESULTS: Our study findings revealed that 0.9 %and 6.5 %of the dental undergraduate students and medical undergraduate students could answer all the questions correctly regarding knowledge of OSA. Based on the assessment of the difference between medical and dental students in terms of knowledge towards OSA patients, significant difference was observed at the significance level of 95%, where p  < 0.05 but no difference found in attitude towards OSA. However, significant difference was found towards attitude on treating OSA patients p  < 0.05. CONCLUSIONS: A difference was observed in the knowledge and attitude on OSA between dental and medical undergraduate students in USM; however, medical undergraduate students had better knowledge and attitude towards OSA than dental students.

Abstract: BACKGROUND: Musculoskeletal disorders are very prevalent among dentists. Of these disorders, carpal tunnel syndrome (CTS) is notable. OBJECTIVE: The aim of this study was to investigate the relationship between the occupational and non-occupational risk factors and CTS among dentists. METHODS: It is a cross-sectional study. We evaluated 106 dentists from dental schools in Tehran. We collected data by a general questionnaire, a hand diagram, and physical examination. A nerve conduction velocity (NCV) test was used to confirm the diagnosis of CTS. The analysis was performed using an independent T -test and logistic regressions on SPSS software. …RESULTS: The prevalence of CTS among dentists was 17.9%. Significant risk factors of CTS included: vibration exposure greater than two hours per day (OR: 2.5), a wrist diameter ratio of greater than 0.7 (OR: 10.14), and female sex (OR: 13.38). CONCLUSIONS: Exposure to the hand-arm vibration should be considered as an occupational risk factor for CTS in dentists. Female dentists should take more preventive measures. Show more

Abstract: BACKGROUND: Using objective anthropometric measurement data and anthropometric ratios, grip strength and hand functionality can be evaluated. OBJECTIVE: The aim of this study was to obtain anthropometric measurements regarding the forearm and hand, to evaluate the hand functionality in addition to hand and finger grip strengths, and to investigate the correlation between these values. METHODS: One-hundred eight-four subjects between 18 and 25 years were included in the study. Forearm and hand anthropometric measurements and ratios were measured. Hand and lateral grip strengths were evaluated. Jebsen Taylor Hand Function Test (JTHFT) was used to assess hand functionality. …RESULTS: A statistically weak and consistently negative correlation between the ratios of forearm length to forearm/wrist circumferences and the ratio of hand length to metacarpal head circumference and hand-lateral grip strengths was found. There was a statistically weak and consistently negative correlation between these ratios and the subtests of JTHFT. It was shown that there was a statistically weak–moderate positive correlation between the hand-lateral grip strengths and JTHFT subtests. CONCLUSIONS: In conclusion, when evaluating grip strength and hand functionality, forearm and hand anthropometric measurements and ratios, which could affect the results, should be considered.

Abstract: BACKGROUND: In office environments, thermal comfort is one of the most significant factor affecting employees’ performance. OBJECTIVE: This study aimed to determine the effects of exposure to low air temperatures on human cognitive performance, physiological responses, and thermal perceptions during mental work. METHODS: Twenty-four volunteers with an age range of 18–30 years participated in this study. The subjects were exposed to four different air temperatures (10, 14, 18, and 22°C) in a climate chamber based on a within-subject design. The n-back, CPT, and PVT tests were employed to evaluate some basic aspects of cognitive performance. Body …physiological responses and the subjective thermal comfort were also measured. RESULTS: When the thermal condition deviated from relatively neutral temperature, the subjects’ cognitive responses significantly disturbed (P  < 0.05), such that the response accuracy was more affected by reduction of air temperature. The blood pressures and heart rate, galvanic skin response, and respiration rate increased as the air temperature decreased (P  < 0.05), such that the galvanic skin response as a stress indicator was more affected. In the test configurations, as a result of decrease in air temperature of 1°C, the finger and body skin temperatures reduced to 0.74°C and 0.25°C, respectively. CONCLUSIONS: The findings confirmed that low thermal condition can considerably affect cognitive performance and physiological responses during some office work tasks. The subjects’ thermal comfort votes proposed that air temperature lower than 14 °C can be intolerable for employees during routine mental work. It is suggested that personalized conditioning systems should be used to provide individual thermal comfort in moderate cold air conditions. Show more

Abstract: BACKGROUND: The safety and health of healthcare workers employed in pathology laboratories and exposed to formaldehyde (FA) is a matter of concern worldwide, as several health effects have been observed in workers resulting from exposure to FA, both short and long-term. OBJECTIVE: The study was aimed to describe the strategy implemented in a hospital pathology laboratory to minimize workers’ exposure to FA through interventions to working environment and workforce. METHODS: The NIOSH 2016 method for detecting gaseous FA was adopted to perform personal and area active sampling of FA. The samples were subsequently analyzed by High …Performance Liquid Chromatography. The exposure to FA was measured before and after improvement interventions. RESULTS: The pre-intervention step showed FA levels exceeding the threshold limit values (TLV) established by ACGIH, both the time-weighted average (TLV-TWA) and short term exposure limit (TLV-STEL); after the improvement interventions, the median concentrations of personal and area FA sampling were respectively of 0.025 ppm (Range = 0.023–0.027) and 0.023 ppm (Range = 0.022–0.028) and significantly lower than pre-intervention step (p  < 0.05) and below the TLV-TWA and TLV-STEL established by ACGIH. CONCLUSIONS: In our study the workers’ involvement in the risk management of FA exposure together with engineering improvements revealed a strategic way to minimize the FA pollution in the studied laboratory. Healthcare companies should consider the need to ensure the workers’ participation in the management of occupational hazards, including FA, to reach the goal of healthy workplaces. Show more

Abstract: BACKGROUND: Rest breaks are an organizational measure to reduce the high risk of upper limb work-related musculoskeletal disorders (UL-WMSDs) to which slaughterhouse workers are subject. OBJECTIVE: To analyze the effect of different work-rest schedules on ergonomic risk in poultry slaughterhouse workers. METHODS: A total of 36 repetitive tasks was selected in a Brazilian slaughterhouse. Using the Occupational Repetitive Action (OCRA) Checklist, the level of exposure of workers to risk factors of UL-WMSDs in two work-rest schedules was evaluated. In the real condition, 6 rest breaks of 10 minutes were performed, and in the simulated condition, 3 …rest breaks of 20 minutes. RESULTS: The right side of the body presented a higher score on the OCRA Checklist (72%of the tasks) than the left side (p  = 0.037) in the real condition. Additionally, the OCRA score (18.3±2.5) was significantly lower (p  < 0.001) than the simulated condition (21.9±3.0). It was verified that the risk level in simulated condition remained the same in 13 (36%) tasks, while in 23 (64%) tasks there was an increase in the risk level. CONCLUSIONS: Work-rest schedule of 6 breaks of 10 minutes was better than 3 breaks of 20 minutes to reduce the risk of UL-WMSDs in poultry slaughterhouse workers. Show more

Abstract: BACKGROUND: Long-haul truck drivers are disproportionately exposed to metabolic risk; however, little is known about their metabolic health and the role of physical activity and other risk factors in metabolic outcomes. OBJECTIVE: This study compares truck drivers’ insulin sensitivity, and associations between metabolic risk factors and insulin sensitivity, with those of the general population. METHODS: Survey, anthropometric, and biometric data were collected from 115 long-haul truckers, which were then compared to the general population data using the National Health and Nutrition Examination Survey (NHANES) dataset. The quantitative insulin sensitivity check index (QUICKI) was used to estimate …insulin sensitivity. RESULTS: Truck drivers had lower QUICKI scores than the general population cohort. Sagittal abdominal diameter and exercise were predictive for QUICKI among combined cohorts. Waist circumference and perceived health were more predictive for QUICKI among truck drivers, and sagittal abdominal diameter and income were more predictive for QUICKI among the general population. CONCLUSIONS: Long-haul truckers appear to represent a subset of the general population regarding the impact of physical activity and other metabolic risk factors on QUICKI. Accordingly, comprehensive efforts which target these factors are needed to improve truckers’ physical activity levels and other metabolic risks. Show more

Abstract: BACKGROUND: Psychosocial risks and work-related stress are one of the most complex, most significant and most challenging problems that organizations around the world are facing. Stress negatively affects all participants in the organization and significantly contributes to negative health consequences and economic outcomes. OBJECTIVE: With timely identification and adequate assessment of psychosocial risks, it is possible to create healthy workplaces and healthy organizations where employees are satisfied and motivated. The paper will present the results of the research of psychosocial risks on a large sample of respondents in the Republic of Serbia. METHODS: A questionnaire was …distributed to 1,212 participants of which 1,140 answered all the questions asked. Data from the questionnaire were analyzed using multiple regression analysis, Kolmogorov-Smirnov test, Spearman’s correlation coefficient and Pearson’s chi-square test (χ2). RESULTS: The results of multiple regression analysis showed that all psychosocial risks taken together are statistically significantly (p < .001) and explain 24%of the variance of the criteria. CONCLUSIONS: Psychosocial risks identified as statistically significant predictors are Labor Demands, Interpersonal Relations, Lack of Support, Work Role and Job Uncertainty. All predictors are statistically significant predictors at the level.01. Show more

Abstract: BACKGROUND: Previous studies have shown high rates (47–72%) of self-reported work-related musculoskeletal disorders (WRMDs) in surgeons of the head and neck. Physical requirements in the workplace, individual factors (e.g. poor posture, obesity) and psychosocial factors have been identified as risk factors. Establishing biomechanical risk factors may help prevent further development of WRMDs in this population. OBJECTIVE: The purpose of this critical review was to source studies that identified the biomechanical risk factors for WRMDs in this surgical sub-specialty. METHODS: Searches were conducted of Medline, CINAHL, and AMED databases from 1980 until September 2018. RESULTS: …A total of 182 article were identified. Exclusion criteria lead to 163 full-text articles being screened, generating a total of 6 articles for review. The aims of the included studies varied significantly. Surgeons spend the majority of operating time in static, asymmetrical positions. Surgical loupes/headlamps significantly increased cervical spine loading. Articulated surgical arm supports provided optimal ergonomic conditions. Performing surgical operations with the surgeon in standing or sitting had no effect on task performance or demand. Physical fatigue was also measured in both positions. CONCLUSIONS: A combination of equipment-based and patient/surgeon position-based factors predispose surgeons to biomechanical risk factors. Studies of greater methodological quality are required. Show more

Abstract: BACKGROUND: In November 2016, the government of India declared 86%of the total money in circulation as demonetized. This policy was brought into effect overnight, and it had great macro socioeconomic impact not only on the economy of the country but on the common people, especially the socioeconomically challenged. While several researchers have focused on, and continue to investigate, the effects of demonetization on the economy, its impact on the psychosocial health of workers has not yet been studied. OBJECTIVE: To provide an exploratory investigation of the psychosocial consequences of demonetization on the workers in Indian tea gardens. …METHODS: A qualitative research approach was employed. Face-to-face interviews were conducted with seven key informants (clinicians and executives/managers), and 36 tea garden workers were involved in six focus groups. Collected data were analyzed using the Template Analysis technique. RESULTS: From the data analysis, five main themes emerged concerning the psychosocial factors involved in demonetization effects: socioeconomic changes, organizational consequences, workplace interpersonal relationships, work-family interface, and psychophysical symptoms. CONCLUSIONS: This preliminary study highlighted the significant impact that demonetization had on tea gardens at both the organizational and individual levels. Show more

Abstract: BACKGROUND: Several studies have suggested that trait and ability-based measures of emotional intelligence (EI) contribute to the promotion of well-being in adults. However, this relationship has not been sufficiently explored among adolescents. OBJECTIVE: The present study aims to: i) investigate the associations between EI dimensions and well-being indicators (self-esteem, life satisfaction and social anxiety) in adolescents; and ii) analyze the effect of sex and age on dimensions of EI. METHODS: The sample consisted of 1066 adolescents (57.9%girls and 42.1%boys), aged between 11 and 18 years (M = 14.36; SD = 1.58). Participants completed sociodemographic and validated psychosocial measures. …RESULTS: Correlation analysis indicated that EI dimensions (self-emotion appraisal, use of emotions and regulation of emotions) were positively and moderately correlated with self-esteem and life satisfaction, whereas associations between EI and social anxiety dimensions were small and negative. Boys reported higher levels of self-emotion appraisal, use of emotions and regulation of emotions, whereas girls showed higher levels of other-emotions appraisal. Age was negatively associated with the use of the emotions dimension and positively correlated with the emotional appraisal of others, although both correlation coefficients were small. CONCLUSIONS: Our study findings suggest the need and importance of implementing emotional education practices during adolescence. Show more

Abstract: OBJECTIVE: This article aims to demonstrate the ways in which port workers collectively respond to task demands, work organization and functional turnover instituted in a Portuguese port. METHODS: Based on both the theoretical debate on the cooperative aspects during the performance of the activity and the contextual research matrix of the activity ergonomics, the investigation conducted focused on the room for maneuvering that is assigned to the work teams and, more specifically, how collective action materializes more visibly in the elaboration of new rules of action with a view to the arbitration between the preservation of health, the …guarantee of safety and the response to the required performance levels. RESULTS: The results of the analysis of port activity make evident the development of a high degree of operational synchronization between the professional skills articulated in the team, specialized communication in certain work subprocesses, and strategies for collective surveillance of risks.

Abstract: BACKGROUND: Work-related mental health problems are a primary cause of disability and lead to the absence of 500,000 workers each week in Canada. There is a growing body of literature suggesting integrated approaches of prevention are necessary to improve mental health at work. The involvement of numerous stakeholders inclusive of government agents, employers, and workers is recommended. However, only minimal information is available to suggest actions workers may adopt toward an integrated approach of prevention to improve mental health at work. OBJECTIVE: The aim of the study was to identify behaviors workers may adopt to foster mental health …at work. METHODS: Following a descriptive qualitative research design, semi-structured interviews were conducted with researchers, professionals, and workers. Data were analyzed using a template analysis strategy. RESULTS: A total of 49 concrete behaviors were identified, grouped into ten sub-themes, and three broad themes. These main themes identify those behaviors that appear to be useful throughout the prevention continuum: 1) adopting a reflexive practice, 2) acting for one’s own mental health, and 3) acting for mental health of others. CONCLUSIONS: In harmony with the integrated prevention approach, this study offers a framework to organize workers’ concrete actions contributing to mental health. Show more

Abstract: BACKGROUND: There are a few studies conducted on job stress dimensions and their relationship with Low Back Pain (LBP) among Iranian nurses. OBJECTIVE: The aim of the current study was to investigate the association between job stress dimensions assessed via Demand-Control-Social Support (DCS) and Effort-Reward Imbalance (ERI) models and prevalence of LBP among Iranian hospital nurses. METHODS: In this cross-sectional study, 495 randomly selected nurses of Shiraz University of Medical Sciences (SUMS) participated. Demographic/occupational questionnaire, the Persian version of the Job Content Questionnaire (P-JCQ) and the Persian version of the ERI Questionnaire (P-ERIQ) were used for …data collection. Data were analyzed by SPSS software (version 19) using descriptive statistics, independent sample t -test, and logistic regression. RESULTS: The LBP prevalence was found to be 69.9%. The means±standard deviations of job stress dimensions were obtained as follows: decision latitude: 64.67±6.82, physical job demands: 15.52±2.6, social support: 23.18±3.65, psychological job demands: 38.02±4.98, effort: 8.73±2.62, reward: 23.12±5.31, over-commitment: 12.25±3.09, and effort-reward ratio: 0.86±0.3. The findings revealed that the work experience (OR = 1.56), psychological job demands (OR = 1.082), and effort-reward ratio (OR = 3.43) were predictors for LBP among the study population. CONCLUSION: The prevalence rate of LBP among studied nurses was high. About half of nurses had high psychological demands, low decision latitude and low social support. Based on the effort-reward ratio, nurses had experienced high level of stress. Interventional programs and coping strategies for reduction of work-related stress and, subsequently, prevention of LBP are recommended among hospital nurses. Show more

Abstract: BACKGROUND: Low back pain (LBP) is common in personal care attendants because this profession requires much physical work. Information about the prevalence of LBP and LBP-associated risk factors in this group is limited. OBJECTIVE This study aimed to investigate the 1-year prevalence of LBP and identify LBP-associated factors in female hospital-based personal care attendants. METHODS: Forty-seven female hospital-based personal care attendants were recruited. The Nordic Musculoskeletal Questionnaire was used to investigate the prevalence of LBP during the recent 12 months. Participants completed a personal traits and associated factors questionnaire. Physical fitness and the knowledge test of …body mechanics were assessed. Multivariable logistic regression analysis was used to explore LBP-associated factors. RESULTS: The 1-year prevalence of LBP was 46.8%. The strongest LBP-associated risk factor was poor abdominal muscle endurance, followed by insufficient knowledge on the test of body mechanics and higher psychological stress. CONCLUSIONS: The results demonstrate that the prevalence of LBP in female hospital-based personal care attendants appears to be high. Preventive programs should be initiated to reduce LBP-associated risk factors, such as improving abdominal muscle endurance, providing education in the proper use of body mechanics, and providing psychological intervention services for female hospital-based personal care attendants.
