Abstract: BACKGROUND: The literature discussing musculoskeletal diseases of inner northeastern workers is scarce, although 67,559 cases were reported in Brazil between 2007 and 2016. OBJECTIVE: This study aimed to evaluate the effect of multiple risk factors that influence the symptoms of work-related musculoskeletal disorders (WMSDs) in wrists, elbows, and shoulders in workers from four different economic sectors. METHODS: A sample included 420 workers from the inner regions of the Brazilian states of Alagoas and Bahia. The Nordic Musculoskeletal Questionnaire was used to capture pain symptoms on both sides of the body (left and right). Sociodemographic variables, items …from the biomechanical exposure and organizational conditional, in addition to other questionnaires (JCQ, COPSOQ II, ERI) were used to assess the characteristics and occupational risks of the respondents. Ordinal logistic regression model was using to identify the relationship between symptoms and factors. RESULTS: This study highlights the psychosocial, biomechanical, occupational, and sociodemographic variables contributed to development of WMSDs. Use of hand-vibrating tool increased the likelihood of symptoms manifesting on the body. On the other hand, high job control and high job insecurity reduced the likelihood of developing symptoms. On the other hand, high job control and job satisfaction reduced the likelihood of developing symptoms. Factors such as age, curved spine, high job insecurity and excessive commitment contributed to the development of WMSDs only on one side of the body. CONCLUSIONS: The development of WMSDs is multifactorial. Sociodemographic, occupational, biomechanical, and psychosocial factors may commonly contribute to WMSD manifesting only on one side of the body more than on both sides. Show more

Abstract: BACKGROUND: Work-related musculoskeletal complaints (WMSCs) are induced or aggravated by work activities and/or work conditions. OBJECTIVE: The aim was to evaluate the impact of work as a massage practitioner, with a special emphasis on WMSCs. METHODS: Massage practitioners were invited to participate in the study through an advert in the rehabilitation medical clinics. The participants completed a self-administered questionnaire, collecting general data and questions about WMSCs. RESULTS: Thirty-seven subjects (88.09%) reported pain in at least one body part in the last 4 weeks. The most common WMSCs was pain in …the neck region (69.04%), followed by pain in the shoulder region (54.76%), upper back (52.38%), lower back (40.48%), wrist-hand (33.33%) and elbow (21.43%). The massage practitioners aged between 21 and 30 years old reported significantly more frequently WMSCs localized in neck, shoulders, wrist-hand, upper back and lower back. CONCLUSIONS: This study shows that WMSCs are widely reported among massage practitioners. The most common complaints were reported in the neck and shoulder regions, especially in younger massage practitioners. Show more

Abstract: BACKGROUND: Companies have tried to carry out interventions in order to mitigate the risks associated with losses in productivity and the health of employees. OBJECTIVE: This intervention trial evaluated the effect of a supervised exercise intervention based on aerobic capacity and strength on well-being at work and capability in performing work tasks. METHODOLOGY: The sample was composed of 67 participants (N = 67, mean age 34.31 years) and investigated a 12-week group physical exercise program in the workplace, two days per week for 50 minutes, which was supervised and based on aerobic endurance and strength. The 67 subjects …were working-age office workers, deemed sedentary and randomized into an intervention (N = 40) or control (N = 27) group. Among them, 33 were men (N = 33; 49.25%) and 34 were women (N = 34, 50.75%). Outcomes were assessed pre- and post-test in both groups. The Mann-Whitney U and Chi-Square tests were performed to compare the characteristics of the intervention and control group. η 2  = z/(n-1) was calculated as effect size rates. RESULTS: The program showed statistically significant effects on strength endurance (P  = 0.020, η 2  = 0.08), the loss of fat percentage (P  = 0.015, η 2  = 0.09), lower limb power (P  = 0.020, η 2  = 0.08) and QoL (P  = 0.0001, η 2  = 0.39 for the physical health outcome, and P  = 0.0001, η 2  = 0.35 for the outcome of total scores of mental health). CONCLUSIONS: The intervention had an impact on the endurance, fat percentage loss and QoL of the workers whose occupations were based on sedentary tasks. Show more

Abstract: BACKGROUND: Sedentary tasks contribute to the deterioration of health and the appearance of chronic diseases. Physical exercise can contribute to the development of health, although the characteristics of the most appropriate program are unknown. OBJECTIVES: This is the second paper of the PRODET® intervention trial evaluating the effect of a supervised group exercise intervention in the worksite based on aerobic capacity and strength lasting 12 weeks. METHODS: The sample was composed of 67 subjects (N = 67, mean age 34.31 years) and the study investigated a 12-week group physical exercise program in the workplace, two days per week …with 50-minute sessions, which was supervised and based on aerobic endurance and strength. The 67 subjects were working-age office workers, deemed as sedentary and randomized into an intervention (N = 40) or control (N = 27) group. Outcomes work ability, depression, anxiety and job satisfaction were assessed with questionnaires pre-and post-test in both groups. RESULTS: The program showed effects on the mental factor of work ability (Z = 2.36, P = 0.019, η 2  = 0.09). However, there were no significant differences in the rest of the results. CONCLUSIONS: The intervention had an impact on the mental factor of work ability in the workers whose occupations were based on sedentary tasks, and reinforcing this variable with an exercise program in the workplace could contribute to reducing the mental factor of work ability.

Abstract: BACKGROUND: The construction industry is one of the most dangerous industries in terms of occupational accidents. Understanding the various factors that affect work-related injuries and deaths in the industry can help develop prevention strategies, improve safety performance and reduce accidents. OBJECTIVES: This applied qualitative study was carried out in several steps to investigate, evaluate and prioritize the causes of occupational accidents in the construction industry. METHODS: In order to extract the most important criteria in construction accidents, the opinions of safety experts and the qualitative Delphi method were used. The Fuzzy Analytic Hierarchy Process (FAHP) was …used to determine the weights of selected criteria and finally, the Fuzzy TOPSIS technique was used to rank the causes of occupational accidents in the construction industry. RESULTS: According to the results, governance, occupational, organizational, individual, and environmental factors were the most determinative options for the cause of construction accidents. Prioritizing the causes of occupational accidents in the construction industry using Fuzzy AHP and Fuzzy TOPSIS showed that governance and environmental factors were the most effective and least effective factors in construction accidents, respectively. CONCLUSIONS: According to the criteria, and based on fuzzy TOPSIS technique, governance factors were determined to be the primary option for occupational accidents in the construction industry. The results of this study indicate that in addition to organizational factors, individual factors, and environmental factors, the government must also play a role in legislation, law enforcement, implementation, and organization of safety training programs.

Abstract: BACKGROUND: Imbalance between flexor and extensor muscles of the trunk could negatively influence spinal stability. OBJECTIVES: Investigate the strength balance between flexor and extensor muscles of the trunk in military firefighters with non-specific chronic low back pain (NSCLBP). METHODS: One hundred and two male firefighters were assessed in an isokinetic dynamometer at 120°/s and 60°/s to investigate the balance ratio between flexor and extensor (F/E) muscles. RESULTS: An F/E ratio of 0.72 (SD: 0.22; 95% CI: 0.67–0.76; SEM: 0.02) was observed at 60°/s and 0.94 (SD: 0.41; 95% CI: 0.85–1.03; SEM: 0.04) at 120°/s. …The mean peak torque of the extensor muscles was 343.1 N.m/Kg (SD: 94.87; 95% CI: 322.8–363.5; SEM: 10.23) at 60°/s and 270.5 N.m/Kg (SD: 113; 95% CI 246.3–294.8; SEM: 12.18) at 120°/s. The mean peak torque of the flexor muscles was 232.4 N.m/Kg (SD: 53.86; 95% CI 220.8–243.9; SEM: 5.81) at 60°/s and 223.8 N.m/Kg (SD: 66.34; 95% CI 209.6–238.1; SEM: 7.15) at 120°/s. All torques generated by the extensor muscles were higher than the flexor muscles (p  < 0.05). CONCLUSIONS: Firefighters with NSCLBP presented a normal F/E balance ratio and higher strength of extensor muscles of the trunk. Show more

Abstract: BACKGROUND: Teachers experience high work-related stress, which can lead to missed workdays and lower quality of life. OBJECTIVE: The objective of this exploratory pilot study was to assess occupational and environmental stressors in public school districts by income level to examine the influence these stressors have on teachers perceived stress and biological stress response. METHODS: Fifty-nine teachers were recruited from four school districts in Michigan (three low-income and one high-income). Participants completed a self-administered survey on teaching stressors, health, and demographics. Stress response was measured through blood pressure, heart rate, and salivary cortisol. Six salivary cortisol …measurements were collected for each participant; three in the afternoon and three in the evening. Each teacher’s classroom and school underwent an environmental assessment on quality and proximity to environmental hazards. RESULTS: Teachers at low-income school districts had significantly higher afternoon cortisol levels, lower self-reported health, higher body mass index, higher perceived teaching stressors, and worked at schools within one km of a greater number of environmentally-contaminated sites, in comparison to their high-income school district counterparts. CONCLUSIONS: This research aims to inform future interventions that could lessen occupational and environmental stressors for teachers, improve teacher health outcomes and retention, and impact student success rates.

Abstract: BACKGROUND: Rice farming is considered the most crucial industry in India, where millions of farmers suffer from LBP. OBJECTIVES: The present study’s primary objectives were to evaluate the prevalence of low back pain among India’s rice farmers and determine the relationship between low back pain and ergonomic risk factors and psychosocial factors encountered by the farmers. METHODS: Socio-demographics, ergonomics risk factors and psychosocial factors that cause LBP among rice farmers were examined. Modified Nordic Musculoskeletal Questionnaire and Oswestry LBP Questionnaire were administered among the farmers to evaluate the LBP. Univariate analysis was done to find out …the odds ratios and 95% confidence intervals among the farmers. RESULTS: The primary findings from this study regarding the psychosocial factors, such as perceived inadequacy of income (84.7%), job demands (78.1%), work demand targets specific productivity (76.5%), rigidity in work methods (75.3%), monotony at work (73.2 %), have a relationship with LBP. The results also revealed that the relationship between the low back pain and ergonomic risk factors, such as repetitiveness (OR- 4.215; 95% CI- 2.551–6.965), working in awkward posture (OR- 85.82; 95% CI- 43.134–170.77), lifting loads (OR- 0.281; 95% CI- 0.125–0.324), pulling loads (OR- 0.274; 95% CI- 0.173–0.434), showed significant relationship with LBP in the univariate analysis. CONCLUSIONS: The prevalence of LBP among rice farmers connected with ergonomic and psychosocial risk factors. The awkward posture, MMH (lifting and carrying) are the main causative factors of LBP.

Abstract: BACKGROUND: Craniocerebral injuries belong to the category of bodily injuries which are characterised by high mortality and a high percentage of permanent effects in the form of disability. The likelihood of this injury exists in the workplace too. Performing works at a height or using high-pressure or mechanical machinery exposes employees to a higher risk of a craniocerebral injury. CASE REPORT: This case study deals with the topic of open craniocerebral trauma suffered by a 20-year-old man who was wearing no head protection at his place of work. It details the management of this trauma at the site …of the accident, during transfer to the hospital and during hospitalisation. CONCLUSION: Fast transport, effective diagnostics and implementation of surgical treatment contributed to a good final result. Show more

Abstract: BACKGROUND: The limited research has focused on the relationship between work-related stress and self-efficacy in relation to mental health problems in nurses. OBJECTIVE: This multi-hospital cross-sectional survey investigated the relationships between work-related stress, self-efficacy and mental health status of hospital nurses in Tabriz, Iran. METHODS: Four hundred hospital nurses completed a questionnaire including demographic and job details, Health & Safety Executive (HSE) Management Standards Revised Indicator Tool (MS–RIT), General Self-Efficacy (GSE–10) scale, and General Health Questionnaire (GHQ–28). A three-step hierarchical logistic regression modelling was used. RESULTS: Work-related stress, self-efficacy and mental health problems …were significantly related to each other. The results of the regression modelling revealed that working overtime and number of patients cared for were significant positive predictors, while job tenure as well as control and relationships dimensions of work stress were significant negative predictors of mental health problems, with the final model explaining 21% of the variance in the outcome measure. Addition of self-efficacy at step 3 did not result in a significant change in the variance from previous steps. CONCLUSIONS: The results provide further support for stress prevention strategies focused at the job (e.g., better organisation of work demands) and organisational (e.g., improving employee participation and involvement in work) levels.

Abstract: BACKGROUND: Musculoskeletal disorders are important health problems due to their high incidence as well as their effects on the society and individuals. OBJECTIVE: The aim of this study was to determine the musculoskeletal disorders experienced by teachers, and to evaluate their relationship with certain factors causing musculoskeletal disorders. METHODS: The cross-sectional study was carried out on 416 teachers working in a provincial center using the face-to-face interview method. RESULTS: Per this 64.9% of the teachers had musculoskeletal disorders, and the pain was mostly localized in the neck region with 55.5%. The work stress scores …of the teachers were found to have a positive and significant correlation with musculoskeletal disorder scores and a negative significant correlation with the satisfaction with life scores (p ≤0.001). In multiple regression analysis, the time spent sitting at a desk, time spent working in a standing position, time devoted to housework, shoe preference, work stress and life satisfaction were determined as effective predictors on musculoskeletal complaints. The model that was developed explained 22.5% of the variance (R2  = 22.5; p ≤0.001). CONCLUSIONS: Due to the prevalence of musculoskeletal disorders among teachers, health-promoting actions are needed in order to raise the awareness of both administrators and teachers in improving working conditions as well as preventing musculoskeletal disorders.

Abstract: BACKGROUND: Although the number of farmers in Korea is declining, the proportion of older farmers aged ≥60 increases. OBJECTIVE: This study aims to analyze gender differences in working conditions, exposure to risk factors, and health problems of older crop farmers aged ≥60. METHODS: This study used data from the 5th Korean Working Conditions Survey (KWCS) data of 818 male and 985 female crop farmers aged ≥60 years. RESULTS: This study showed that older female farmers had higher ratios of living alone (45.0% vs. 13.4%, p  < 0.001), lower education levels (80.7% vs. 53.4%, p  < 0.001), …and lower average incomes (1.565 vs. 2.036 million KRW, p  < 0.001) than that of males. Among subjective scores on the exposure of risk factors, only females’ repetitive motion (4.923) and awkward posture (4.415) scores were higher than that of males’ repetitive motion (4.601) (p  < 0.001) and awkward posture (4.159) scores (p  = 0.001). However, female’s health problem rates on upper limb pain (68.3%), lower extremity pain (67.6%), backache (48.4%), overall fatigue (44.8%), and headache and eyestrain (25.0%) were higher than that of male’s complaint rates on upper limb pain (48.5%) (p  < 0.001), lower extremity pain (53.3%) (p  < 0.001), backache (35.0%) (p  < 0.001), overall fatigue (39.5%) (p  = 0.024), and headache and eyestrain (19.4%) (p  = 0.005). The rate of depression symptoms in females (54.6%), with a high proportion of single-person households, was higher than that of males (46.9%) (p  = 0.001). CONCLUSIONS: The musculoskeletal pains and depression symptoms of older female farmers are prevalent, and efforts and support are required to improve working conditions. Show more

Abstract: BACKGROUND: Paramedics are a high-risk occupational group for posttraumatic stress injuries (PTSI), and increasingly, evidence suggests that organizational factors play a significant role. While several resources for paramedic services to address PTSI exist, there is limited knowledge as to which PTSI-related programs and practices are implemented and how they are perceived in the workplace. OBJECTIVES: This research aimed to explore key informants’ perspectives on existing and desired organizational-wide initiatives for, as well as the challenges and potential solutions to, the primary prevention, early detection and intervention, and disability management of PTSI in Canadian paramedic services. METHODS: …Semi-structured interviews were conducted with 12 key informants from jurisdictions across Canada who have over five years of work experience in prehospital care. Interviews were audio-recorded, transcribed, and analyzed using thematic analysis. RESULTS: Eight recurrent organizational elements (themes) for addressing PTSI emerged: psychologically safe and healthy work culture; consistent supervisor support, mental health training and awareness, opportunities for recovery and maintaining resiliency, recognition of PTSI and its diverse risk factors, access to a variety of support initiatives for PTSI, communication during medical leave, and meaningful work accommodations. CONCLUSIONS: While organizational-wide initiatives were in place for the primary prevention, early detection and intervention, and disability management of PTSI, systemic challenges with coordination, resource allocation, and worker engagement were also identified. These challenges prevented paramedic services from optimally addressing PTSI in their workplace. Integrating considerations from the eight organizational elements to address PTSI into broader existing management systems may have merit in overcoming the systemic challenges. Show more

Abstract: BACKGROUND: To overcome the poor conditions of low-income areas in developing countries like Brazil, Community Health Workers (CHWs) are required to exceed the regular set of formal skills they are used to employ. OBJECTIVE: In this study, we aim at identifying the non-technical skills CHWs must develop to cope with the extraordinary situations that occur in vulnerable communities. METHODS: 41 CHWs based in two primary healthcare clinics in Brazil underwent two rounds of in-depth interviews. The analysis was carried out using the Analytical Hierarchy Process, resulting in the prioritization of social skills according to their calculated …importance to house calls. RESULTS: Among the ten higher-scored skills, we find communication and advocacy skills being of high importance. Civility was found to be the most important attribute, confirming that community action relies strongly on the relationship between health professionals and the community. CONCLUSION: The results of our study contribute primarily to the improvement of community-based primary care programs as it helps to identify major skills required for community action. Show more

Abstract: BACKGROUND: Anthropometric data should be considered for each major population age category, specifically because of the dimension changes occurring during ageing. In elderly subjects, the physical activities and their capabilities become limited. Therefore anthropometric reference data for equipment and system designs is necessary. OBJECTIVES: The aim of the study was to collect data for the body dimensions of an elderly Iranian population and evaluate the related gender and age correlations. METHODS: Nineteen body dimensions were manually measured on a sample size of 317 subjects (167 male and 150 female) from four provinces of Iran. A pilot …preliminary test for assessing test-retest reliability on ten body dimensions using the Intraclass Correlation Coefficient (ICC2 :1)  was performed. Descriptive statistics were reported based on gender and independent samples t -tests to compare the anthropometric dimensions of both genders and age. RESULTS: Results indicated higher dimensions in males, except for hip-breadth (p  = 0.87). In all subjects, increasing age corresponded with: decreased standing shoulder height, eye height, and elbow height; and with sitting height and sitting knee height; while hip-breadth increased. Reliability was acceptable (ICC2.1 >0.88). In the elderly, as with adult subjects, there are significant gender differences in body dimensions, and this should be considered in equipment and system design. Furthermore, this study demonstrated both genders differences and the consequences of aging. CONCLUSIONS: From this pilot data, product designers can consider the anthropometric characteristics for elderly Iranian subjects for equipment and system design. Show more

Abstract: BACKGROUND: Mercury used in dental amalgams constitutes a significant source of chronic exposure to this heavy metal among dentists. Thus, the safety of dental amalgam remains a controversial issue despite its long history of use. In Morocco, most studies about dental mercury were mainly focused on the environmental risk related to the management of mercury-contaminated waste. OBJECTIVE: In order to evaluate the occupational exposure to mercury among liberal dentists practicing in two Moroccan regions, a multidimensional statistical approach was used to analyze the collected data. The main objective was to help establishing a targeted prevention plan aiming to …reduce the mercury exposure among Moroccan dentists. METHODS: Fifteen variables from 146 dentists were elected for a three-step classification procedure: a multiple correspondence analysis followed by a hierarchical ascendant clustering consolidated by the k-Means algorithm. RESULTS: Three homogenous clusters were identified. The most important one includes 57.5% of the population as well as the majority of the risky factors. The characterization of these clusters allows proposing concise guidelines for a targeted preventive plan. CONCLUSIONS: A real mercurial risk has been observed in the studied population. However, its impact on health as well as the efficiency of simple preventive recommendations remains to be unveiled. Show more

Abstract: BACKGROUND: Early studies have revealed the psychological effects of the COVID-19 outbreak on healthcare workers (HCWs). Burnout and psychological outcomes of different medical professions during the pandemic have not yet been addressed. OBJECTIVE: The study aimed to investigate the burnout, depression, anxiety, and psychological distress levels of HCWs, and to determine the predictive factors of burnout in different professions of frontline HCWs during the pandemic. METHODS: This cross-sectional study included 253 HCWs (79 physicians, 95 nurses, and 79 other-HCWs). The Maslach Burnout Inventory, Beck Depression Inventory, Beck Anxiety Inventory, and Impact of Event Scale-Revised, and Sociodemographic …Form were used. RESULTS: Emotional exhaustion was significantly higher in physicians and nurses than in other frontline HCWs. While depersonalization was significantly higher in physicians than nurses / other HCWs, levels of avoidance, hyperarousal and intrusion were found to be higher in other HCWs / nurses than physicians. Depression was the most effective predicting variable for burnout, following age, quarantine, supervisor’s/team leader’s attitude, hyperarousal and avoidance. CONCLUSIONS: It has been observed that depending on the uncertainty and life risk of the pandemic in HCWs involved in the treatment of COVID-19, physicians who are the decision-making authorities in the treatment process used more depersonalization than nurses and other HCWs. Nurses and other-HCWs had significantly higher distress symptoms than physicians. Both future research and psychosocial services should address those with high depressive symptoms as a potentially fragile subgroup for burnout among HCWs, and investigate and develop evidence-based interventions that can provide mental well-being, and prevent burnout.

Abstract: BACKGROUND: The intensive care unit (ICU) is a complex, dynamic, high stress and time-sensitive place. While a variety of rules and regulations provided to reduce medication errors in recent years, many studies have emphasized that medication errors still happen. OBJECTIVE: The purpose of this investigation is to predict, reveal and assess medication errors among surgical intensive care unit (SICU) nurses. METHODS: This study was performed in one of the public hospitals in Shiraz, namely Shahid Faghihi hospital. The human error assessment and reduction technique (HEART) method was adopted to measure and assess medication errors in the …ICU. RESULTS: Findings indicate that ICU nurses perform 27 main tasks and 125 sub-tasks. The results also showed that setting and using DC shock task has the highest human error probability value, and assessment of patients by a nutritionist has the lowest human error probability value. CONCLUSION: Medical errors are key challenges in the ICU. Therefore, alternative solutions to mitigate medication errors and enhance patient safety in the ICU are necessary. Although the technique can be used in healthcare; there is a need to localize the coefficients and definitions to achieve more accurate results and take appropriate controls. Employing experienced people and providing conditions that reduce the possibility of errors in nurses, increasing the number of staff, and developing specialized and simulated training were identified as the most important control strategies to reduce errors in nurses.

Abstract: BACKGROUND: Establishing strategies for improving nursing shortages, which are labor challenges in the current health care industry. OBJECTIVE: This study aimed to examine the correlation between workplace bullying and organizational citizenship behavior (OCB) in nurses and the mediating effects of job satisfaction on this relationship. METHODS: A total of 164 valid samples were obtained. The Negative Acts Questionnaire-Revised, the Minnesota Satisfaction Questionnaire, and an OCB scale were measured. RESULTS: The results indicate that a significantly larger proportion of nurses working in operating rooms (Δ odds ratio, odds = 2.30, p  = 0.043), the emergency room, and …the ICU (Δ odds = 2.79, p  = 0.019) had suffered workplace bullying compared with nurses working in patient wards. No experience of workplace bullying exerted a positive and significant effect on job satisfaction (p  < 0.001), and job satisfaction exerted a positive and significant effect on overall OCB (p  < 0.001). No experience of workplace bullying exerted a significant mediating effect on the influence of job satisfaction on overall OCB (p  < 0.001). CONCLUSIONS: The department of service in which a nurse works influences the occurrence of workplace bullying, previous experience with bullying reduces job satisfaction, and greater job satisfaction promotes higher OCB performance. Based on the study results, we advise that nursing executives address and prevent workplace bullying to increase the job satisfaction of nurses so that nurses are willing to display OCB, apply their expertise, and expand the role and functions of nursing.

Abstract: BACKGROUND: This study compares Canadian and German healthcare workers employment status and wages based on age, gender, and educational training. The German and Canadian healthcare systems are rarely compared, that if such a comparison between the two countries is available, can provide an insight of health workers employment status and how that might affect the wellbeing of elderly. OBJECTIVES: The study investigates the relation of age, gender and post-basic training with annual employment and income of health care workers in Canada and Germany. METHODS: Secondary data on age, gender, post-basic education training, employment status and average …monthly wages/salary was obtained from the German Socioeconomic Panel and the Canadian Survey of Labor and Income Dynamics data. The German dataset comprised 571 healthcare workers, including 219 nurses, 231 elder carers and 121 care assistants. The Canadian dataset comprised 2,580 healthcare workers, including 947 nurses, 493 elder carers and 1,140 care assistants. RESULTS: Primarily, there was a strong relationship between post-basic training and wages for both the Canadian and German samples among elder carers and care assistants. Older healthcare workers (46 years old and above) were generally employed, and age had no predictive power on annual labor earnings. This difference in age was significant among the Canadian than the German nurses. Post-basic training had a significant relation with annual earnings and monthly wages in both the Canadian and German samples. CONCLUSIONS: This study suggests that the socio-demographics of healthcare workers as age, gender and advanced training are associated with their employment opportunities, financial rewards, and better career opportunities. The relationship between demographic variables helps understand the relation of healthcare workers employment dispositions and how it might improve the quality of life of older people in nursing homes, hospitals and elderly private homes in Canada and Germany.

Abstract: BACKGROUND: Many cross-sectional studies have examined the predictors of neck pain among adolescents and working-age populations, but there are limited studies included undergraduate students. OBJECTIVE: To investigate the predictors of neck disability among undergraduate students. METHODS: A cross-sectional study using a self-administered online survey. Students completed the survey that included socio-demographic factors, academic-related factors, health and lifestyle factors, and standardized questionnaires including Neck Disability Index (NDI), 12-Item Short-Form Health Survey (SF-12), Depression Anxiety Stress Scales (DASS-21), and Pittsburgh Sleep Quality Index (PSQI). Students who reported an NDI score higher than 15 were considered as having a …neck disability. A multivariable logistic regression model was used to identify the significant predictors of neck disability. RESULTS: Of all students (n  = 1292), 20.8% reported neck disability. Among all possible predictors, students’ major satisfaction (OR 1.46 [95% CI 1.06–2.01]; p  = 0.019), DASS-21 anxiety score (OR 1.06 [95% CI 1.03–1.09]; p  < 0.001), SF-12 total score (OR 0.89 [95% CI 0.86–92]; p  < 0.001), and PSQI score (OR 1.21 [95% CI 1.15–1.28]; p  < 0.001) were the only significant predictors of neck disability. CONCLUSIONS: Increased levels of academic stressors and anxiety, and decreased levels of quality of life and sleep quality are associated with increased neck disability among undergraduate students.

Abstract: BACKGROUND: Nursing is associated with many stressful situations that can lead to fatigue, reduced efficiency, and physical and mental illness. Safety climate is one of the most important indicators of safety management performance assessment that assesses employees’ attitudes towards safety issues. OBJECTIVE: The purpose of this study was to investigate the relationship between safety climate and occupational fatigue in nurses. METHOD: This descriptive-analytical study was performed on nurses working in hospitals affiliated to Zabol University of Medical Sciences in 2019. 143 nurses were selected by the proportional sampling method and entered the study. Demographic questionnaires, Occupational …Fatigue Inventory (SOFI), and Nurses’ Safety Assessment Questionnaire were used for data collection. Statistical tests, including Independent T -Test, ANOVA, Mann-Whitney U, Kruskal-Wallis, and multivariate analysis of variance (MANOVA) were used to analyze the results using SPSS software version 21, and the multivariate structural equation was used for modeling. RESULTS: The mean scores of safety climate and occupational fatigue were 67.15±12.73 and 85.09±41.49, respectively. Job and demographic variables except for the second job (P -value = 0.065) had a significant effect on the variables of safety climate and occupational fatigue. There were also higher scores for occupational fatigue and all of its subscales in the group of women compared to the group of men. CONCLUSION: The results showed that occupational and demographic variables have significant effects on safety climate and occupational fatigue. There was a significant relationship between demographic variables of age, work experience, and education level with safety climate. There was also a significant relationship between education level, job satisfaction, satisfaction with colleagues and work experience with occupational fatigue. Therefore, paying attention to fatigue and safety climate of nurses in workplaces is recommended. Show more
