Abstract: BACKGROUND: Aging is a process that includes progressive physiological changes. Grip strength is an important indicator of current health in the elderly. OBJECTIVE: The aim of the study was to examine the correlation between dominant-hand grip strength (HGS) and cognitive function, mid-upper arm circumference, muscle-bone mass, balance, mobility, and daily life activities in elderly individuals living in nursing homes and determine the effect rates of these factors on HGS. METHODS: Seventy-two elderly individuals aged over 65 who lived in a nursing home were included in the study. Dominant HGS and mid-upper forearm circumference were measured. Muscle …and bone masses were measured with bioelectrical impedance analysis. Mid-upper arm circumference was measured using a non-elastic tape. HGS was measured using a hand dynamometer. Cognitive function was evaluated with the Standardized Mini-Mental Test (SMMT); mobility and balance were evaluated with the Timed Up and Go Test (TUGT) and Berg Balance Scale (BBS); the Katz Activities of Daily Living Scale (KATZ ADL) was used to evaluate daily life activities. RESULTS: There was a significant correlation between HGS and muscle and bone masses (p  < 0.001). A significant correlation was found between HGS and TUGT, ADL (p  = 0.001, p  = 0.016). There was no significant correlation between HGS and BBS (p  = 0.2). There was a correlation between HGS and SMMT at the statistical significance limit (p  = 0.055). On HGS, the Body Mass Index had a 64.9% effect; the muscle mass had a 30.9% effect; the TUGT had a 27.7% effect. These parameters were found to explain 59.9% of the variance. CONCLUSION: As a global indicator of muscle strength, HGS can be used to predict age-related functional changes. Approaches to increase physical activity levels in elderly can be effective in reducing age-related negativities. Show more

Abstract: BACKGROUND: Smartphones are very convenient and accessible communication devices. Smartphone usage over long durations with poor posture can lead to musculoskeletal pain in adult users. OBJECTIVE: To compare pain in the neck, shoulder, upper back, lower back, arm, hand, and eye regions. METHODS: Thirty-five asymptomatic adults aged 18-25 years were divided into two groups: 1. use of an innovative smartphone app for the promotion of ergonomic behaviour (app use) and 2. no use of the innovative smartphone app (no app use). Participants sat upright, holding a smartphone with two hands, eyes 30-40 cm away from the screen, …with frequent breaks consisting of stretching the neck and hand muscles while resting the eyes. The task involved taking part in online social networking for a duration of 45 minutes. A body pain chart and the visual analog scale (VAS) were used to evaluate the location and severity of pain. RESULTS: Pain in the neck, shoulder, upper back, arm, and hand regions in the “app use” condition were significantly lower than in the “no app use” condition at 15, 30, and 45 min (p -value<0.05). However, there were negligible differences between the two groups for eye pain, and lower back pain. CONCLUSION: Pain in the neck, shoulder, upper back, and arm regions in adult users in the “app use” condition was less than in the “no app use” condition. We would recommend that adults use the innovative smartphone app to prevent the risk of musculoskeletal pain potentially caused by smartphone usage. Show more

Abstract: BACKGROUND: Job-related psychosocial factors have a substantial effect on the occurrence of adverse events among healthcare professionals. OBJECTIVE: An analytical and descriptive survey was conducted to evaluate the relationship between the occurrence of patient safety incidents and psychological factors. METHODS: The study sample consisted of 177 nurses who were asked about patient safety events over six months. Repetitive patient safety incidents were selected by examining medical records and interviewing specialists. Also, psychological factors were assessed using job content questionnaire (JCQ). RESULTS: Repetitive patient safety incidents were involved medication administration error, pressure ulcer and skin-muscular …injuries, patient falls, inability to CPR patients, blood transfusion reactions, and death due to human error. The findings showed that 92 participants (52%) had at least one case of patient safety incident. Among patient safety incidents, medication administration error and death due to human error had the highest and lowest repletion, respectively. Nurses training, job insecurity and peer support were significant predictors of different aspects of patient safety (p  < 0.05). CONCLUSION: Proper collaboration between new and experienced nurses can have a significant impact to reduce patient safety incidents. In addition, nursing training can be a good way to understand risk points in medical errors. Show more

Abstract: BACKGROUND: There is willingness in Europe to implement the use of a biopsychosocial model such as the International Classification of Functioning, Disability and Health (ICF) for assessing work incapacity. OBJECTIVE: A preliminary study was conducted to investigate the perceptions of medical advisers on the value of structuring clients’ biopsychosocial information in an ICF-based report. METHOD: A sample (n  = 101) received a perception questionnaire after watching two comparative videos based on a clinical case. Questions relating to work incapacity were also asked. The data was analysed using quantitative methods. Comments were also collected. RESULTS: Before …knowing the ICF-based report, 61.96% of the respondents believed a return to work seems possible by providing adapted work or a different job. There is an increase of 8.69 pp (p-value: 0.077) after reading the report. Opening up the initial sample to more insurance physicians (n  = 119), the difference is more significant (p-value: 0.012). Also, 71.9% of respondents believe they have a better view of the client’s biopsychosocial situation after reading the report. Respondents recognise the clinical and diagnostic relevance of ICF but say it cannot be used at the moment for various reasons, such as the time required or the need for a multidisciplinary team and effective coordination. Older respondents are less enthusiastic about the appropriateness of using ICF. CONCLUSION: The respondents identify an added value in having a biopsychosocial based-report. After learning about the report, more physicians see opportunities for professional re-integration than before. The medical advisers and their team must be strengthened and receive a clear role in order to empower them. Show more

Abstract: BACKGROUND: Backpacks used by children is a global concern, because may cause musculoskeletal discomforts and pain. OBJECTIVE: The purpose of this study was to test the usability and effects on gait kinematics wearing the Trunkpack versus a traditional backpack and no backpack. METHODS: Twenty-four children (9 to 11 years old) from a public school participated in this study. The usability was evaluated after a five-week testing period using a questionnaire. Gait kinematics was evaluated (Vicon) when the children were wearing a standard backpack, an optimized backpack (Trunkpack), and no backpack. Both backpacks were loaded with 10% …of body weight. RESULTS: Was observed more trunk, hip and knee flexion when the children carried a standard backpack in comparison using the Trunkpack and not carrying a backpack (p  < 0.01). The Trunkpack and no backpack were similar. The Trunkpack was well accepted by the schoolchildren (81% positive responses), 79% liked the head opening, 88% liked the waist straps, and 83% liked the facility to put and take objects in and out of the Trunkpack. CONCLUSION: Trunkpack requires less postural adjustments during gait than a standard backpack. Gait kinematics with the Trunkpack was comparable to the gait without carrying a backpack. Show more

Abstract: BACKGROUND: New technologies for ships affect many aspects of seafarers’ lives at work. Nowadays, many shipowners provide their ships with internet access for the personal use of the crew. After all these developments, nomophobia is no longer a phenomenon far from seafarers. Nomophobia affects mental health and motivation in seafarers, like all people who can use smartphones. Until now, there has been no study investigating nomophobia in seafarers and its effects on life at sea. OBJECTIVE: This study aimed to determine the prevalence of nomophobia among seafarers and examine the causes and consequences of differences between groups. …METHODS: A previously designed and tested questionnaire was used to determine nomophobia and its effects on seafarers. Three hundred fifty one seafarers participated in the study. ANOVA and T-tests were performed with SPSS 22 package program to find significant differences. RESULTS: Nomophobia differed significantly according to age groups, gender, and education level. Headache and fatigue increased in direct proportion to the level of nomophobia. CONCLUSION: It was found that 65.2% of the seafarers had moderate to severe nomophobia. Show more

Abstract: BACKGROUND: Occupational stress is one of the most important factors affecting nurse performance. However, there is a lack of data about the association between occupational stress and performance. OBJECTIVE: The aim of this study was to determine the occupational stress level and its association with job performance in hospital staff. METHODS: This cross-sectional study was conducted among 400 hospital staff of Tehran University of medical sciences in 2018. Subjects completed the World Health Organization Health and Work Performance questionnaire (WHO HPQ) for demographic and occupational characteristics, and the Short Form of Copenhagen questionnaire. RESULTS: …The demand and individual interface domain received the highest and the lowest score of occupational stress respectively. We found that the median for absenteeism distribution was 16 hours and, in our study, less than 10 % of the nurses had low performance. Working in intensive care units, fewer night shifts, higher income, higher levels of vitality, and social support could decrease absenteeism. In addition, staff who felt more supported and reported lower emotional demands had higher performance. CONCLUSION: Since higher levels of social support could have positive influences on reducing absenteeism and improving performance, it is recommended that hospital managers should be encouraged to use educational programs, coping behaviors, and effective interventions to improve social support. Financial incentives are a factor that could also be used to reduce absenteeism. Show more

Abstract: BACKGROUND: The findings of the effectiveness of physical activity on adults’ cognitive abilities have not yet been transferred into corresponding fields of application. OBJECTIVE: The present study evaluates a motor-cognitive coordination programme in a company to improve employees’ cognitive performance in the short and medium term. METHODS: A total of 67 employees — 32 men and 35 women aged between 19 and 61 years — participated in this study, and 55 completed the study. The sample was randomly divided into an experimental group, which received a motor-cognitive coordination training, and a control group, which received a …relaxation and mobility training. Both groups met for 15-minute sessions three times a week for eight weeks. Before and after the intervention, working memory, attention, information-processing capacity, divergent thinking, and mood were measured. In addition, acute effects regarding attention and mood were tested. RESULTS: The results showed that the motor-cognitive coordination break improves working memory and divergent thinking after eight weeks of intervention, whereas neither the mood nor the information processing speed improved more for the experimental group compared to the control group. The results on the acute increase in attention performance failed to reach significance. CONCLUSION: The new approach of this study was not only the derivation and development of targeted exercises, but also their testing and evaluation in the field of application. Motor-cognitive coordination exercise in the workplace might play an important role in both occupational health management and personnel development, especially for companies that are under highly competitive and innovative pressure.

Abstract: BACKGROUND: The hand anthropometric data is the baseline for design of hand tools and equipment. OBJECTIVE: This study aimed to generate the hand anthropometric database of male and female agricultural workers and compare it with the hand anthropometric data of other regions of India. The use of collected data is illustrated to design hand tools and protective gear. METHODS: Hand anthropometric data were collected from 228 male and 198 female agricultural workers of northeast India. A total of 35 hand dimensions, stature and body mass from different tribes in the age group of 18–60 years were …precisely measured. Measured data were statistically analysed to study the effects of gender, ethnicity, and age on hand dimensions. Correlation coefficients were determined among hand dimensions and linear regression equations were developed between highly correlated dimensions. RESULTS: The results show that all hand dimensions of the male and female subjects are significantly different (p  < 0.01). Most of the hand dimensions were significantly different (p  < 0.05) among different tribes for the male subjects. However, less number of hand dimensions were significantly different among tribes for the female subjects. Age of the subjects has significant effects (p  < 0.01) on dimensions related to thickness, depth and circumference of fingers. The use of these data in the ergonomic design of hand tools and personal protective gear is illustrated to increase safety and comfort as well as efficiency of operators. CONCLUSION: There is a difference in the hand dimensions of different tribes of northeast India. This needs to be considered when designing agricultural hand tools and equipment. Show more

Abstract: BACKGROUND: One of the most important steps for the successful designing, execution, and sustainability of a workplace wellness program is the evaluation stage. OBJECTIVES: The purpose of this research was to create a comprehensive wellness profile through selected and reliable testing protocols used for the evaluation of health, functional capacity, and physical fitness in office employees. METHODS: One hundred office employees (32–55year-old) were evaluated to create a comprehensive wellness profile. Health indices (body composition, blood pressure, respiratory function, lipidemic profile), musculoskeletal pains, functional capacity, physical fitness (cervical, handgrip, back, leg strength, cardiorespiratory fitness), and lifestyle behaviors …(physical activity levels, viewing habits, smoking, alcohol consumption) were measured. Thirty of the participants performed two assessment sessions to examine the reliability of functional capacity and physical fitness indices. RESULTS: A significant proportion of employees were overweight (40.7%) and obese (18.5%). The largest percentage of employees (78%) presented musculoskeletal problems in various areas of the body (higher rates in lower back, neck, and/or hip). A large percentage of the employees (40–65%) showed low-moderate levels in selected indices of health, physical activity (<6000 steps/day), functional capacity and physical fitness, and high levels of unhealthy lifestyle behaviors. The test-retest reliability for the assessment of functional capacity and physical fitness profile was high for all testing variables (ICC = 0.92-0.99; SEM%  = 2.5–4.5). CONCLUSION: The testing protocols are reliable and can be used in conjunction with the reference values created to evaluate selected health and wellness indicators in office-employees. Show more

Abstract: BACKGROUND: In Japan, women’s participation in the workforce has been increasing. However, there are few studies about gender differences in stress factors in the workplace. OBJECTIVES: We aimed to clarify gender differences in psychosocial factors in the workplace related to severe stress. METHODS: In total, 930 male and 339 female employees working in a construction company in Japan participated in this study. We used individual responses to the Brief Job Stress Questionnaire (BJSQ) conducted by their company for the most recent year between 2016 and 2019. Data were categorized by gender, and we extracted the factors …contributing to severe stress using logistic regression. RESULTS: We identified 142 men and 32 women who had severe stress. Logistic regression analysis showed that six factors (“Qualitative job overload”, “Job control”, “Interpersonal conflict”, “Poor physical environment”, “Supervisor’s support”, and “Job satisfaction and life satisfaction”) were significantly associated with the presence of severe stress in men. In women, five factors (“Qualitative job overload”, “Job control”, “Interpersonal conflict”, “Suitable work”, and “Job satisfaction and life satisfaction”) showed a significant association with severe stress. CONCLUSION: Factors associated with severe stress were “Poor physical environment” and “Supervisor’s support” in men, and “Suitable work” in women. Show more

Abstract: BACKGROUND: The dropping out of university students is a serious problem faced by higher education all over the world. Studies have shown that academic hardiness is a positive psychological variable to prevent students from dropping out of university and academic burnout. Psychological hardiness can reduce the dropping out by increasing university students’ academic engagement and academic achievement. OBJECTIVE: This study aims to discover the influence of psychological hardiness on university student’s academic achievement and the mediating role of academic engagement in the relationship between psychological hardiness and academic achievement. A cross-sectional study was conducted among 615 participants. …METHODS: Pearson correlation coefficients were conducted to analyze the relationships between psychological hardiness, academic engagement and academic achievement. Mediation analysis was used to evaluate the mediating role of academic engagement in the relationship between psychological hardiness and academic achievement. RESULTS: The research indicated a closely significant association between psychological hardiness, academic engagement and academic achievement. Psychological hardiness can directly predict academic achievement and can also indirectly predict academic achievement through the intermediary effect of academic engagement. CONCLUSION: This study could have important implications for research by linking psychological hardiness and academic achievement. The results suggest that universities should pay attention to the positive role psychological hardiness plays in improving university students’ academic achievement. This study also benefits the university administrators, especially, those dealing with university students at the risk of dropping out and high academic stress. Show more

Abstract: BACKGROUND: Work-related musculoskeletal disorders (WRMSDs) are a significant occupational health concern in radiographers. OBJECTIVE: This study aimed to describe radiographers’ WRMSDs symptoms prevalence and severity, exploring associations with occupational risk factors. METHODS: A cross-sectional study was conducted to explore WRMSDs symptoms and occupational risk factors in radiographers of Western Switzerland using an online survey, based on the Nordic Musculoskeletal Questionnaire (NMQ). Descriptive statistics were conducted to analyze the collected data, and associative statistics to identify the risk factors related to symptoms. RESULTS: Participants (n  = 359) presented a high prevalence of WRMSDs symptoms in the …last 12 months (94.7%), with a related absenteeism rate of 15.6%. In the last 7 days, symptoms prevalence was 67.7%. The most affected anatomical regions, over both time periods, were the neck (73.0%, 36.8%) and low back (67.4%, 35.7%). Associative statistics underlined risk factors affecting significantly radiographers’ health (OR >2) were the “awkward postures” (OR = 2.86; 95% CI 1.78–4.58) and “feeling anxiety/stress at work” both for low back (OR = 2.38; 95% CI 1.39–4.08), and being a woman for the neck (OR = 2.64; 95% CI 1.51–4.61). CONCLUSIONS: There is a high WRMSDs symptoms prevalence in Western Switzerland radiographers. Radiographers’ work demands namely for awkward postures increases the odds for WRMSDs symptoms presence, affecting predominantly neck, upper and lower back. Our data suggest that further research is needed to implement adapted prevention to this specific context. Show more

Abstract: BACKGROUND: Using both hands is regularly needed for force/torque exertions in many activities, especially when using hand tools. OBJECTIVE: To investigate the effects of tool grip span, workpiece orientation, moving direction, and working height on two-handed wrist U/R deviation torque strength, usability, comfort, and discomfort while using locking pliers. METHODS: Participants (n  = 22) took part in an experimental study which evaluated the effects of tool grip span (4.5–6.5 cm), workpiece orientation (transverse/sagittal), moving direction (clockwise (CW)/counterclockwise (CCW)), and working height (shoulder/elbow/knuckle) on two-handed wrist U/R deviation torque, (dis)comfort, and usability while using locking pliers. RESULTS: …The results showed no significant effect of tool grip span on wrist U/R deviation torque strength, but the locking pliers with 4.5 cm handle grip span led to more comfort and better usability. The two-handed wrist U/R deviation torque strengths were significantly higher in sagittal plane than in transverse plane, and in CW direction than in CCW direction. The highest values of two-handed wrist U/R deviation torque strength in sagittal and transverse planes were exerted in knuckle and elbow heights, respectively. CONCLUSION: The findings can be used to develop guidelines and recommendations with regard to daily and occupational activities which require the use of both hands for force exertion with manual hand tools.

Abstract: BACKGROUND: The weak preventive culture among workers in the construction sector leads to the underestimation of risks posed by the presence or handling of chemical agents on-site and, consequently, harms workers’ health. OBJECTIVE: The objectives of this paper are to classify exposure to chemical agents present or used on-site, determine workers’ perception of said agents and establish the influence that socio-demographic variables have on chemical agent exposure and the perception of such exposure. METHODS: A total of 490 workers in the Spanish construction sector participated in this study. The data were gathered through a self-administered questionnaire …that explored socio-demographic characteristics, the degree of exposure to chemical agents, attitudes toward exposure and the prevention of consequences. The underlying dimensions of perception were researched using an adapted version of the questionnaire used by the Paul Slovic group to apply the psychometric paradigm. RESULTS: The levels of exposure to and handling of chemical agents found in the sample were high and moderate, respectively. The participants were found to have advanced knowledge about the effects of exposure, with the majority of the workers considering the probability of suffering a serious disease to be low. Statistically significant associations were found between the socio-demographic variables identified in the sample and the various exposure characteristics. A factor analysis performed on the underlying dimensions of perception provided a final version of the instrument comprising two factors. CONCLUSION: Measures are needed to improve the preventive culture among workers in the construction sector and reinforce on-site preventive measures aimed at preventing or minimising the consequences of exposure to chemical agents.

Abstract: BACKGROUND: In recent times, Saudi Arabia has experienced growing industrialisation and more opportunities for business requires more human capital if it is to become one of the largest economies in the world and such growth brings with it some health issues. OBJECTIVE: The study aimed to provide analytical illustration of occupational injuries among the workforce in Saudi Arabia. To accomplish the study purpose, four measurements were carried out, the occurrence of occupational injuries, the severity of occupational injuries, the patterns in occupational injuries, and the occupational injuries in relation to the demography of the injured employees. …METHODS: A retrospective study was designed based on a secondary data of occupational injuries (OI) that was obtained from the General Organization for Social Insurance. Descriptive analysis was used to describe the occurrence and the outcome of OI. Multivariate regression was applied to the patterns in OI and to those injuries in relation to the demography of the injured employees. RESULTS: Within two years, Riyadh Province had the highest occurrence of OI (30.6%). Construction and Elementary occupations had the highest occurrence of OI (36.3% and 45.7% respectively). Injuries’ occurrence differed significantly between months. Fridays significantly associated with low injuries. Among demography, injuries differed significantly in relation to the employees’ age. CONCLUSIONS: There was no noticeable decrease in death cases from an earlier local study while they were less compared to other nations (Turkey and South Korea). Compared to other nation, Islamic holidays that are characterized by heat waves were not associated with increased OI. Preventive measures are insufficient. Show more

Abstract: BACKGROUND: Years ago, the use of asbestos in construction materials was common. Although asbestos has been recently banned in many countries, exposure to asbestos during old building demolition is not unexpected. OBJECTIVE: The aim of this study is to assess the concentration of exposure to asbestos and estimate its cancer risk among old building demolition workers. METHODS: In this study, personal air samples were collected during building demolition. The number of asbestos fibers in collected samples were determined according to the NIOSH-7400 standard method. Chemical compositions of fibers were assessed using scanning electron microscopy (SEM). The …carcinogenic risk of exposure to asbestos was determined based on the recommended United State Environmental Protection Agency (USEPA) method and Monte-Carlo simulation used to estimate the probability of cancer. RESULTS: Chemical analysis confirmed the presence of asbestos in collected air samples, and 67% of counted fibers were asbestos. In a number of buildings, workers had exposed to asbestos that was higher than occupational exposure limit (0.10 f/ml). Results of cancer risk estimation showed that cancer risk were considerable among workers. CONCLUSION: Implementation of asbestos risk management program such as separation of asbestos containing material, personal protective equipment’s and use of wet method in demolition could minimize asbestos exposure during old building demolition.

Abstract: BACKGROUND: New York City’s (NYC’s) taxi/for-hire vehicle (FHV) drivers have occupational and demographic characteristics associated with food insecurity (low income, comorbidities, minority race/ethnicity). OBJECTIVE: To analyze food insecurity rates in a sample of NYC drivers and to identify associated factors. METHODS: At health fairs, we recruited a cross-sectional sample of licensed taxi/FHV drivers willing to receive study text messages. Most lacked a primary care provider. Food insecurity prevalence and associations with health and economic indicators were analyzed. RESULTS: Of 503 participants who completed a 2-item food security screener, 39.2% were food insecure. Significantly fewer …food insecure than food secure drivers reported a doctor visit within the past year (48% vs 25%; P  < .001). Food insecure drivers had greater weekly traffic ticket expenditure ($34 vs $24; P  = .02) and were more likely to report insufficient household income (61% vs 39%; P  < .001) and history of depression (14% vs 7%; P  = .02), to have elevated (>200) measured total cholesterol (50% vs 37%; P  = .02), and to have Perceived Stress Scale scores indicating greater stress than food secure drivers (14 vs 11; P  = .002). In a binary logistic regression analysis, drivers who reported that their total household income was enough to meet their basic needs had significantly lower odds of being food insecure (0.695 odds ratio; P  = .016). CONCLUSION: Food insecurity was high in this group of taxi/FHV drivers. Food insecurity interventions are needed and could be occupationally based, with worksite screening and resource navigation. Policies should address improving wages and healthcare access. Show more

Abstract: BACKGROUND: Most ergonomics assessment tools for repetitive task have been used in industries which are mainly focused on assessing the biomechanical risk factors that affect musculoskeletal disorders (MSDs) rather than the psychosocial and work environment risk factors. OBJECTIVE: To develop a tool for Repetitive Task Risk Assessment (RTRA) and Rapid Upper Limb Assessment (RULA) that can identify biomechanical, physical stress and psychosocial risk factors, prioritize risk reduction action and systematic record keeping. METHODS: The study consisted of 2 phases; tool development and evaluation of the contents of risk factors by 7 ergonomic experts and intra-rater and …inter-rater reliability and validity tests of the tool by 1 researcher and 9 Thai practitioners to assess 30 repetitive tasks. RESULTS: RULA was modified by adding more biomechanical risk, combining psychosocial and work environment risk factors lead to MSD become the first prototype of RTRA. The Item-Objective Congruence Index (IOC) validated 20 items on usability of each step of the RTRA ranged between 0.64 and 0.93. The examination of the overall intra-rater reliability was 0.932 (95% CI: 0.862–0.967) and the overall inter-rater was 0.956 (95% CI: 0.909–0.978). CONCLUSION: The tool has high test-retest reliability. There is a suggestion for researchers to understand more on the identification of multiple risk factors in one assessment tool and consider a risk-level rating and scoring for prioritizing risk reduction.
