Have young workers more injuries than older ones? An international literature review

Occupational injury prevalence and predictors among small-scale sawmill workers in the Sokoban Wood Village, Kumasi, Ghana

BACKGROUND

Sawmill workers are at increased risk of occupational injuries due to their exposure to workplace hazards. However, little is known about the burden of occupational injuries among them in Ghana. Understanding its prevalence and associated factors is necessary to design appropriate interventions to improve workers' health and safety. This study sought to determine the prevalence and factors associated with occupational injuries among small-scale sawmill workers at Sokoban Wood Village, Kumasi.

METHODS

A cross-sectional study was conducted among 138 small-scale sawmill workers from December 2020 to January 2021. Data was collected on demographic and work-related characteristics including age, sex, personal protective equipment (PPE), workspace design, and lighting. The primary outcome was the prevalence of occupational injuries in the 12 months preceding the survey. Logistic regression method was used to assess for independent predictors of occupational injuries, and associations were deemed statistically significant at p < 0.05.

RESULTS

Approximately 66.7% of the workers experienced occupational injuries within the 12 months preceding the study. Cuts (69.6%) were the most commonly reported injuries. Injuries were mainly caused by machine parts/sharp objects (47.8%) and being hit by logs/objects (46.8%). Only 40.7% of the workers reported always using PPE while legs (38.0%) and hands (37.0%) were the most common body parts injured. The worker's monthly income, poor workspace design and poor lighting had increased odds of occupational injuries while an increase in age was associated with a 5% decreased odds of occupational injuries.

CONCLUSION

The prevalence of occupational injuries among the sawmill workers at the Sokoban Wood Village was high, and this calls for prioritization of health and safety at the workplace. Essential measures required include improvements in the safety of machine tools, workspace design and lighting.

Risk self-perception and occupational accidents

INTRODUCTION

This study analyzes the relationship between measures of occupational accidents and workers' perception of risk in the workplace using nationally representative data on workers' characteristics and a complete record of occupational accidents.

METHODS

Regression analyzes addressing both the ordinal nature of the dependent variable and causality were conducted to control for different sociodemographic factors influencing workers' perceptions of occupational risks. Special attention was paid to the risk level of the worker's workgroup, existence of family responsibilities, organizational safety culture, and measures of accident rates.

RESULTS

Individuals showed different perceptions of risk based on their personal and work characteristics. Significant associations were observed between each variable of interest and risk perception. Overall, the results remain robust across specifications addressing both simultaneity and ordinality.

CONCLUSIONS

Employees' "reading" of hazards was not fully aligned with objective information on occupational accidents but depended on individual characteristics. Having family responsibilities or being unionized increased workers' risk perception, whereas belonging to a workgroup with higher accident rates reduced it.

PRACTICAL APPLICATIONS

Knowing how workers perceive risk and how this perception deviates from statistical information on accidents are essential for management to accurately design safety measures. In this regard, specific characteristics such as age, having dependents in the family, or the typology of the workers' workgroup should be taken into account. Greater knowledge of preventive measures will improve the way workers perceive risk, and ultimately contribute to reducing the likelihood of occupational accidents.

Factors affecting work-related non-fatal injuries among aged workers in South Korea

Introduction

The objective of this paper is to investigate whether an aging workforce is associated with an increase in work-related non-fatal injuries and to explore the underlying reasons for this potential increase.

Methods

Aged workers were defined as those who were at least 55-years-old. Work-related non-fatal injuries were assessed in aged and young workers who were registered with the workers' compensation system from 2017 to 2021 of South Korea.

Results

The mean estimated rate of work-related non-fatal injuries of aged workers (0.88/100) was about 2.5-times higher than that of younger workers (0.35/100). Most work-related non-fatal injuries in the older adults were in individuals working in the "construction sector" (36.0%), those with "elementary occupations (unskilled workers)" (45.0%), and those with employment status of "daily worker" (44.0%). "Trip & slip" (28.7%) and "falling" (19.6%) were more frequent types of work-related non-fatal injuries in aged workers relative to young workers. The category of "buildings, structures, and surfaces" was a more frequent cause of work-related non-fatal injuries in aged workers than young workers.

Discussion

The incidence of non-fatal work-related injuries is higher among aged workers compared to their younger counterparts. The increased occurrence of aged workers participating in precarious employment and jobs, along with the greater physical vulnerability, is likely the cause of their higher rate of work-related non-fatal injuries.

Descriptive analysis and a proposal for a predictive model of fatal occupational accidents in Spain

Accidents at work are a problem in today's economic structures, but if they result in the loss of human lives, the economic and social cost is even higher. The development of prevention policies, both at governmental and sectoral level, has led to a progressive reduction of occupational accidents, but number of fatal accidents remain high. The aim of this study is to explore the evolution of fatal accidents at work in Spain for the period 2009-2021, analyse the relationship between the main variables, and propose a predictive model of fatal occupational accidents in Spain. Data for this study are collected from occupational accident reports via the Delt@ (Electronic declaration of injured workers) IT system. The study variables were classified into five groups: temporal, personal, business, circumstances, and consequences. Fatal accidents at work are more common in males and in older workers, especially in workers between 40 and 59 years old. Companies with less than five workers have the highest percentage of fatal accidents, and the transport subsector and that the worker is carrying out his/her usual work have a strong correlation in the fatal accidents. Results can help to the agents involved in the health and safety management to develop preventive measures, and action plans.

Statistical analysis of the severity of occupational accidents in the mining sector

INTRODUCTION

The aim of this paper is to understand the causes of occupational accidents in Spain's mining sector in order to propose action plans and improve future accident rates.

METHOD

This research analyzed a pool of data on 15,032 accidents occurring in the mining sector and reported to authorities between 2013 and 2018. Accidents are divided into three levels of severity: light, serious, and fatal. We study the influence of 12 variables on the accident severity rate in our sample.

RESULTS

The results show that accident severity is related to age, gender, nationality, length of service, economic activity, company size, accident location, days of injury leave, day of the week, deviation, injury, and specific Spanish region. This sector produces a high rate of serious accidents compared to all other sectors; has a male-dominated, older and experienced workforce; and employs mainly Spanish workers. Its activity is concentrated in larger companies and the work involves the use of heavy machinery and dangerous materials. We offer conclusions and future lines of research to help regulators, companies and workers to improve worker safety.

Burden of injury due to occupational accidents and its spatiotemporal trend at the national and subnational levels in Iran, 2011-2018

PURPOSE

The spatiotemporal trend of the burden of injury due to occupational accidents in Iran, 2011-2018 were assessed at the national and subnational levels.

METHODS

The burden of occupational injury was estimated using three datasets of occupational injury data, the employed population, and duration and disability weight of injuries.

RESULTS

The disability-adjusted life years (DALYs), deaths, DALY rate, and death rate (per 100,000 workers) of occupational injury in Iran drastically decreased from 169,523, 2,280, 827, and 11 in 2011 to 86,235, 1,151, 362, and 5 in 2018, respectively. The DALY rates of occupational injury were significantly different by gender and age in a manner that the DALY rate of men was much higher than that of women and the DALY rates by age group in 2018 ranged from 98 for 50 y and over to 901 for 15-19 y. The shares of injury outcomes in the total DALYs in 2018 were as follows: 63.6% for fatal injuries, 17.4% for fracture, 7.9% for open wound, 7.3% for amputation, and 3.8% for other injuries. Over 83% of the DALYs was observed in three economic activity groups of construction, manufacturing, and community, social, and personal service activities. The three provinces with the highest DALY rates in 2018 were Markazi, West Azarbaijan, and East Azarbaijan, respectively.

CONCLUSION

Despite the decreasing temporal trend, the burden of occupational injury in Iran in 2018 was high. The high-risk groups and hot spot provinces should be taken into more consideration for further reduction of the injury burden.

Fatal work accidents in Ecuador from 2014 to 2020: How the age of the deceased worker relates to the accidents' temporal and geographical characteristics

This article analyzes the relationship between the age of male workers deceased in work accidents and temporal (year, month, day of the week, working shifts), geographic (provinces), and economic sector characteristics in which the accidents occurred in Ecuador between 2014 and 2020. Available data on fatal accidents from the Ecuadorian Social Security Institute (IESS) were collected. The results, which report both frequencies and proportions (rates), indicate that fatal accidents have decreased in the period, although the average age of deceased workers has increased. No significant differences were found regarding the month, day of the week, and work shift, nor in the frequency of accidents or the age of the deceased workers. However, differences were found in terms of geographical areas and sectors of economic activity. This study contributes to the literature as it is the first to analyze the temporal and geographical characteristics of fatal accidents about the age of the deceased worker.

Do social influences, awareness, or experience matter? Toward a better understanding of Farm-related Injury Risk Perception among agricultural science college students in Ireland

Introduction

Formal farm safety education/training should be tailored, in terms of the approach, content and delivery, to students undertaking agriculture education and training to enhance Farm-related Injury Risk Perception (FIRP). To this end, this paper assesses factor(s) explaining or predicting levels of FIRP amongst students studying for a degree in agriculture science.

Methods

A cross-sectional online survey was conducted with a nationally representative sample of Bachelor of Agriculture Science (BAgrSc) students (N = 417) (aged 18-20) in Ireland. Descriptive [frequency and cross-tabulations) and inferential (Ordinal Logistic Regression (OLR)] analyses were applied to evaluate the effects of social influences, experience (of farming, of a near-miss or injury), and awareness (of others who were injured or killed on the farm) on FIRP.

Results

The study found that social influences negatively affected FIRP (P < 0.05). A relatively small number of students reported experiencing an injury (n = 56, 13.4%) that resulted in them being unable to participate in educational or social activities. A quarter of the respondents did, however, record experiencing a near-miss/close call (n = 106, 25.4%). A notable proportion (n = 144, 34.5%) of students had personal connections to someone who died as a consequence of a farm-related incident and 56.4% (n = 235) knew someone who was moderately or severely injured. OLR findings established that experiencing a severe injury, having a near-miss or close call, and awareness of a farm-related death or injury positively affects FIRP (P < 0.05).

Conclusions

Perception of farm risks amongst students in Ireland is low. Students who recorded higher levels of risk perception were, however, more likely to report experiencing a near-miss, close call or severe injury, or knowing someone who experienced a farm-related injury or fatality. Farmers, family or friends were found to negatively impact the FIRP and this reflects previous research findings. Our findings highlight the need for education and training programs to enhance opportunities for student peer-to-peer learning through sharing of experiences and/or knowledge of farm injuries and/or fatalities. Such activities will enhance awareness and understanding amongst the general population of students leading to increased FIRP and contribute to a reduction in risk-taking.

Young workers and safety: A critical review and future research agenda

INTRODUCTION

Research on young worker safety often relies on inconsistent definitions of young workers and poorly delineated indicators of occupational safety. This review aims to reconcile these fundamental issues by critically integrating research across disciplines and providing clear directions for future research on young worker safety.

METHOD

We critically review the extant research on young worker safety.

RESULTS

We first reconcile the inconsistent definitions of young workers and specify the indicators of occupational safety used in young worker safety research. We next describe the prevalence of workplace injuries and population-level predictors of these injuries among young workers and then outline other factors that increase young workers' susceptibility to workplace injuries. Finally, we discuss the convergence of many of these issues on family farms-a context commonly studied in young worker safety research.

CONCLUSIONS

Clearer definitions of young workers and indicators of occupational safety can improve the interpretation and comparability of extant research findings. Furthermore, the prevalence of workplace injuries and population-level predictors of injury among young workers are subject to the interactions among age, gender, minority status, and job characteristics. Other factors that increase young workers' susceptibility to injury include young workers' responses to hazardous work, individual differences stemming from young workers' biological and psychological development, managerial attitudes about young workers, and the limited safety training young workers are thus provided, the types of work that young workers typically perform, and the range of social influences on young workers.

PRACTICAL APPLICATIONS

Safety campaigns and safety training should consider interactions among young workers' age, gender, minority status, and job characteristics, rather than considering these features independently.

Cross-Regional Research in Demographic Impact on Safety Consciousness and Safety Citizenship Behavior of Construction Workers: A Comparative Study between Mainland China and Hong Kong

The construction industry has rapidly developed with continuous prosperity in Hong Kong and Mainland China, although accidents still occur with unacceptable frequency and severity. For promoting the safety issue of workers in construction industry, safety citizenship behavior (SCB) and safety consciousness (SC) were considered two influential constructs and further studied with integration of sociodemographic theories by scholars. However, no study has compared the SC and SCB of construction workers in terms of the demographic influence between Mainland China and Hong Kong. To fill this research gap, this study investigated the territorial difference between these two regions by conducting a cross-sectional questionnaire survey with recruitment of 253 Mainland construction workers and 256 Hong Kong construction workers. Significant similarities and differences of SC and SCB performance were revealed in terms of the workers with different genders, education levels, weekly working hours, and ages. This study provides insights into the comparison of demographic influence on SC and SCB of construction workers between Hong Kong and Mainland China, which is unique as it can yield useful managerial knowledge relevant to the personal safety of targeted groups of construction workers with particular demographic characteristics in both regions and contribute the implementation of safety interventions in line with the specific distinction in the territorial aspect.

Construction Accidents in Spain: Implications for an Aging Workforce

Construction workers are getting older. In the European Union, the percentage of workers over 50 grew from 24.7% in 2011 to 31.5% in 2018, in Spain from 20.4% to 31.2%. Objective. Identify trends and detailed patterns of accidents of older construction workers compared to other age groups. Data and Method. We analyzed construction accidents in Spain from 2011 to 2018 (N = 455,491). The number of accidents and lost working days (LWD) were broken down by occupation, seniority, company size, temporal variables (weekday, hour), trigger, and body part injured and compared for different age groups. Results. Although older worker had fewer accidents, the consequences of accidents were more serious. Those over 50 years had 84% more lost working days (LWD) than those under 24 years, 48% more than those between 25 and 39 years, and 21% more than those between 40 and 49 years. (1) Occupation: the percentage of accidents grew with age for supervisors, lorry drivers, and bricklayers. (2) Seniority: the least experienced (less than 6 months) and the most experienced (more than 6 years) had the most LWD. (3) Company size: there are 24.5% of accidents in companies of less than four workers. (4) Trigger: older workers suffered more falls, both from height and at the same level. (5) Time: the percentage of accidents in those over 50 was higher on Thursdays and Fridays, in the afternoons from 4 to 7 p.m., and after four hours of work. (6) Injury: this shows the longest absences for shoulder injuries for those over 50 years, with an average of 70 LWD.

Formation Mechanism and Dynamic Evolution Laws About Unsafe Behavior of New Generation of Construction Workers Based on China's Construction Industry: Application of Grounded Theory and System Dynamics

Construction workers' unsafe behavior is a major cause of safety accidents and injuries, therefore, a profound understanding of the formation process and evolution laws about construction workers' unsafe behavior is conducive to taking measures to prevent incidents. At present, the new generation of construction workers (NGCWs) born after 1980 are gradually becoming the main force at construction sites in China. Given that generational differences of construction workers can cause the discrepancies in their thoughts and attitudes when engaging in safety-related activities, this study aims to investigate the formation mechanism and dynamic evolution laws about NGCWs' unsafe behavior based on the context of China's construction industry. From the perspective of behavior motivation, in-depth semi-structured interviews with 18 NGCWs and 7 grassroots managers were conducted, and data analysis followed a three-step coding process based on grounded theory. Through continuous comparison, abstraction and analysis, the stimulus-organism-response theory was introduced and expanded to construct a three-stage formation mechanism model. On this basis, the causal diagram and stock flow diagram were developed based on system dynamics principles to reflect the dynamic feedback relationships of the factors in the static formation mechanism model, and simulation was carried out using Vensim PLE software. The results show that three types of internal needs and three types of external incentives stimulate corresponding motivations for NGCWs' unsafe behavior. Two types of individual factors, five types of situational factors and behavior result play an influencing role in the decision-making process of externalizing motivation into behavior. Under the synergistic effect of multiple factors, the level of unsafe behavior displays a downward trend, and the rate of decrease is slow first and then fast. Furthermore, among individual factors and situational factors, safety awareness and safety management system have the most significant effect on the level of unsafe behavior, while situational factors play a more obvious role. The findings can provide theoretical support and practical references to China's construction companies and government departments for the purpose of improving NGCWs' unsafe behavior.

Perspective: Young Workers at Higher Risk for Carcinogen Exposures

Young workers, those under the age of 25, are considered a vulnerable working population, primarily due to their increased risk of injury. In this study we investigate if young workers may also be at an increased risk for occupational exposure to carcinogens. Using the 2006 and 2016 Canadian Census of Population and previously obtained CAREX Canada data, this study aimed to identify sectors and occupations that have high proportions of young workers and where potential exists for exposure to known and suspected carcinogens. Key groups where young workers are likely at a higher risk for occupational exposure to carcinogens were identified. Our work shows that young workers in construction, outdoor occupations, and farming are key groups that warrant further investigation. These specific groups are highlighted because of the large number of young workers employed in these sectors/situations, the high number of possible carcinogen exposures, and the potential for higher risk behavior patterns that typically occur in these types of jobs. While there is no data available to develop carcinogen exposure estimates specific to young workers, it is our perspective that young workers are likely at a higher risk for occupational exposure to carcinogens. Our findings identify opportunities to improve the occupational health and safety for this vulnerable population, particularly for young construction workers, farm workers, and outdoor workers.

Occupational Health and Safety Scope Significance in Achieving Sustainability

A safe and healthy working environment is vital for overall sustainability, due to the fact that it affects opportunities of economic and social development. However, according to the International Labour Organization (ILO), despite the international commitment to Occupational Health and Safety (OSH) via the 2030’s Agenda Sustainable Development Goals (SDGs), work-related accidents are still far too common. Work-related mortality accounts for 5% of all deaths worldwide; a toll which has increased dramatically due to the COVID-19 pandemic. Yet, in the context of COVID-19, new demands on the labour market, such as teleworking, adequate protective measures, and proper use of personal protective equipment when physical presence cannot be avoided, are necessitating new approaches to ensure health and safety. Arguably, education can be viewed as a cross-cutting strategy in advance of a culture of safety for future generations, through strengthening skills and broadening knowledge. Indeed, even though education cannot be considered a panacea, related to SDG 4, which seeks to ensure inclusive and equitable quality education and promote lifelong learning opportunities for all, it can be considered a critical component to deal with OSH issues using a preventive, rather than a reactive, approach. Given this fact, European Agency for Safety and Health at Work (EU-OSHA) has stressed the prevention approach through mainstreaming OSH in education at all levels, and in all fields of vocational and academic training. Aware of the potential of universities to provide graduates the broad-based knowledge to produce labour-market skills including OSH, the aim of this study is to contribute to the discussion on mainstreaming OSH into Greek university education, using Harokopio University (HUA) as a case study. For this purpose, a web-based survey was conducted to address HUA’s students, faculty members, and staff OSH knowledge, risks awareness, and attitudes, as well as their perceptions, opinions, and beliefs about the role of OSH for academia. A statistical analysis depicted respondents’ high level of willingness to contribute to the promotion of OSH, while additional evidence suggests a considerable commitment of the respondents to participate in HUA’s OSH-related training and education.

Analysis on the Subdivision of Skilled Mowing Movements on Slopes

Owing to the aging of the rural population in the hilly and mountainous areas of Japan, mowing on narrow ridges and steep slopes is done manually by the elderly—individuals over 65 years of age. Studies have shown that many accidents that occurred during mowing were caused by workers’ unstable posture, especially when mowing on steep surfaces where there is a high risk of falling. It is necessary to analyze the body movements of mowing workers to elucidate the elements related to the risk of falls. Therefore, in this study, based on a high-precision motion-capture device and a series of experiments with elderly, skilled mowing workers, we focused on the movements of mowing. We sought to identify effective and safe mowing patterns and the factors that lead to the risk of falls. In various mowing styles, compared to the stride (S) and downward (D) mowing patterns, the basic (B) and moving (M) patterns were the most efficient; however, the risk of falls was also the highest among these patterns. While mowing, workers need to pay more attention to their arm strength and take appropriate measures to reduce the risk of falls according to their age and physique. The results can be used as data for the development of fall-detection systems and offer useful insights for the training of new mowing workers.

Analysis of Falls from Height Variables in Occupational Accidents

Fall-from-height accidents are linked to severe and fatal consequences for impacted workers. A better understanding of the related variables is necessary to improve worker safety. This study analyzed all fall-from-height occupational accidents recorded in Spain from 2009 to 2019, selected significant variables, and evaluated the influence concerning the seriousness of the falls from height. Based on a total of 290,583 fall-from-height accidents, the study shows that a male inexperienced worker in a small company working in a non-habitual workplace is more likely to suffer fatal consequences once the accident happens. An improved knowledge of fall-from-height accidents will improve safety conditions. The workers should be trained and informed about their specific risk depending on the variables analyzed. Safety training should consider more risky profiles. Results from the current study can help identify suitable fall prevention and risk mitigation actions in safety programs for companies.

Gender differences in teachers' occupational accidents

The authors stated that the main objective of the current research is to analyze the relationship between the gender of injured teachers and independent variables, such as age, place of the accident, absence days, and severity of the injury, to improve women's occupational health and safety. Teachers' accidents recorded in Spain (N = 136,702) from 2003 through 2018 were analyzed by calculating their incidence rates, using statistical tools for independent samples. Gender differences were found in some of the variables studied. Women were more likely to suffer an occupational accident. Compensation per lost working day was found to be statistically lower for women, but no differences based on gender were found in the absence days due to occupational accidents suffered by teachers. The salary gap should be addressed to avoid gender economic discrimination among injured teachers. Preventive strategies should be developed to mitigate the negative difference caused by gender variables.

The prevalence, seriousness, and causes of teenage work accidents: A gender difference?

BACKGROUND

Teenage workers are prone to a higher injury risk than adult workers, and adult men are prone to a higher risk of work injuries than adult women.

OBJECTIVES

This study aims to examine whether gender differences exist in teenage work accidents, the level of the accidents, their causes, and the types of the injuries.

METHODS

A survey was sent to a sample of 2,800 13-19-year-olds, randomly selected from Registers Iceland. The response rate was 48.6%. A chi-square test, CI 95%, was applied to measure gender differences.

RESULTS

In total, 16.3%of the respondents had at least one work accident, and 1.2%, an accident that lead to more than one week's absence from work. No gender differences were observed in the level of the accidents, but appeared in the types of injuries and their causes. Cuts were the most common injuries of the boys, but burns of the girls. Bone fractures were the most serious injuries of the boys, but sprains of the girls.

CONCLUSION

Work accidents among teenagers are a particular threat to public health. Therefore, all stakeholders need to work together to prevent teenage work accidents in the future; and to keep in mind the gender diversity of the group.

Sense of security when new at work: a thematic analysis of interviews with young adult retail workers in Sweden

Purpose

Positive examples of situations in which young adults new at work experience feeling secure in the role as novice in the work force are here focused. The aim is to analyze how young adults who are new to the labor market express having a sense of security in the workplace. The long-term goal is to strengthen the conditions for the health and wellbeing of workers entering the retail labor market.

Design/methodology/approach

Thirteen individual in-depth telephone/video-interviews were conducted with young adults (aged 18–28) working within the retail sector in Sweden. Using a thematic interview schedule, the interviews focused how the interviewees contextualizing stories on being novice at the labor market. The study is based on those parts of the material in which stories on feeling secure was expressed.

Findings

The analysis resulted in two themes: A sense of security is related to carrying out work safely and a sense of security is related to receiving support. The first theme illuminates how work is structured and safety training respectively contributes to a sense of security and the latter reveal how social support from a variety of sources (managers, colleagues and others outside the work environment) contributes to a sense of security when new at work.

Originality/value

Using a health promoting perspective, the study complements the existing perspectives of challenges faced by novices as they enter working life. Also, the study highlights the importance of including relations outside the workplace when searching for the understanding of the experiences of being new at work. The study indicates that focusing on the sense of security by well-structured work, safety training and social support might contribute to the strive for a sustainable working life for young adults.

The Perceived Occupational Stress Scale

Abstract. This article aims to present the development and test the psychometric properties of the Perceived Occupational Stress (POS) scale, a new brief instrument aimed at rating a worker’s perception of feeling stressed at work. Six studies are conducted on an overall sample of 1,805 Italian workers, to examine both the construct and concurrent validity of the POS scale. The results demonstrate the high internal consistency (α = .82) and test-retest reliability ( r = .86) of the POS scale, as well as its structural validity and concurrent validity with the Maslach Burnout Inventory ( r = .68 with Emotional Exhaustion) and the Effort-Reward Imbalance Questionnaire ( r = .62 with Imbalance and r = .51 with Overcommitment). Moreover, the POS scale is determined to uniquely contribute toward predicting stress-related health complaints, over and above indicators of workplace stressors, as measured by the Health and Safety Executive Management Standards Indicator Tool ( R2change = .06). Overall, the present findings indicate that the POS scale is a valid and reliable instrument for self-reporting occupational stress levels, and it could be used together with existing risk assessment measures of stress, to obtain a comprehensive evaluation of work-related stress.

Interventions for return to work following work-related injuries among young adults: A systematic literature review

OBJECTIVE

To provide a review of current knowledge about interventions aimed to facilitate young adults to return to work following work-related injuries.

METHODS

A systematic review of published literature from the year 2010 and onwards was conducted to identify studies examining return to work interventions for young adults (aged 19-29) following work-related injuries using PubMed and Web of Science. Two reviewers conducted the screening process and assessed the study quality using the National Heart, Lung, and Blood Institute assessment tool for Observational Cohort and Cross-Sectional studies. Due to wide heterogeneity and small number of studies retained post-screening, a descriptive summary analysis of the included studies was conducted.

RESULTS

No studies were identified that focused exclusively on interventions for young adults. However, two studies, in which an age category of young adults was available, were included and assessed for quality. The study populations were primarily suffering from work-related injuries in the lower back or lower limbs. Both studies revealed that return to work interventions using a case manager coordinating and providing consultation, advice, and risk management to multidisciplinary teams was associated with lower sick leave days.

CONCLUSIONS

Despite the emerging evidence that young adults have higher rates of work-related injuries compared to older colleagues, information concerning work-related injuries and return to work interventions specifically targeting young workers is still lacking. Further research is therefore needed to develop and evaluate return to work interventions for the population of young adults.

Assessment of ergonomic exposure, work-related occupational injuries, and prevention: Child work in the brickfield industry in India

Child labor is an infraction of fundamental human rights, and it prevents the children's physical, psychosocial, and psychological development. In India, children have been working in different unorganized sectors as paid laborers. Children were found performing a fair amount of manual, rigorous tasks in the brickfield industry due to socioeconomic disadvantages. Child brickfield workers suffered from musculoskeletal pain and injuries due to working with a heavy physical workload, which hampers the overall quality of life. A study had been conducted among these child brickfield laborers from India during 2011-2017. The study found laceration (38.7% male and 36.9% female) as the primary injury followed by sprain and strain, scratches, avulsion, and fractures among child brickfield workers. The study shows that child workers are highly prone to injuries, mainly toe (23.9% male and 28.1% female), hands (22.0% male and 23.4% female), wrists, feet, ankles, and fingers. The injury rate among male and female child brickfield laborers was 7.64 and 9.52 per 1000 workers. The primary source of injuries in brickfields was due to falling from height. Several risk factors, including biomechanical, work stress, may play a key role in work-related injuries among child brickfield laborers.

Assessing disabling and non-disabling injuries and illnesses using accepted workers compensation claims data to prioritize industries of high risk for Oregon young workers

INTRODUCTION

Young workers are especially vulnerable to occupational injuries and illnesses. There is a continued need to investigate injury burden among young workers across demographics and industry to inform targeted interventions. Workers compensation (WC) claims are important for quantifying work-related injuries and illnesses, however published studies have focused on disabling claims. This study extended previous research on Oregon young workers by including the most recent WC claims data to identify patterns of injury and high risk industries.

METHODS

We obtained all accepted disabling claims (N = 13,360) and a significant portion of non-disabling claims (N = 24,660) on workers aged 24 years and under from 2013 to 2018. Claim count, rate and cost were calculated by year, age, gender, industry, and injury type. A prevention index (PI) method was used to rank industries in order to inform prevention efforts.

RESULTS

Average annual disabling and non-disabling claim rates were 111.6 and 401.3 per 10,000 young workers. Workers aged 19-21 (disabling: 119.0 per 10,000 and non-disabling: 429.3) and 22-24 years (115.7 and 396.4) and male workers (145.3 and 509.0) had higher claim rates than workers aged 14-18 (80.6 and 297.0) and female workers (79.8 and 282.9). The most frequent injury types were "struck by/against" (35.6%) and "work-related musculoskeletal disorders (WMSDs)" (19.5%). High risk industries included agriculture, construction, and manufacturing for both genders combined. For female young workers, the highest risk industry was healthcare.

CONCLUSIONS

This study demonstrated the added value of non-disabling WC claims data. Using both disabling and non-disabling data and PI method, agriculture, construction, manufacturing and healthcare industries were identified as priority workplaces to prevent common and costly injuries among Oregon young workers. Practical Applications: While the industries identified are considered hazardous for all workers, findings in this study can guide targeted research and prevention efforts specific to young workers.

Air pollution and occupational accidents in the Community of Madrid, Spain

Spain is the EU member country with the third highest total number of accidents in work and has the third highest incidence rate. We have performed a descriptive analysis of occupational accidents in the Community of Madrid (Spain) between 2005 and 2013 to study the impact of air quality on the prevalence of occupational accidents, clarifying how vulnerable to air pollution outdoor workers are. In order to evaluate the association between each air pollutant and work accidents, a quasi-Poisson generalized additive model was fitted. The accident rate followed a downward and statistically significant trend (p = 0.001). The year with the highest accident rate was 2006, with 4981 occupational accidents per 100,000. Occupational accidents follow a temporary pattern (there are differences in the number of accidents according to the month of the year and to the day of the week). Exposure to PM10 and NO₂ increases the risk of having an accident at work, especially for outdoor workers. An increase of 10 μg/m³ in daily concentration resulted in increases in accidents for outdoor workers of 2.5% for PM10 and 6.4% for NO₂.

Analysis of Thoroughbred horse farm workers' compensation insurance claims in Kentucky: Injury frequency, cost, lost time, and associated occupational factors

BACKGROUND

Thoroughbred horse farm workers self-report a high frequency of work-related injuries and pain. However, an analysis of Thoroughbred horse farm workers' compensation injury claims is absent from the literature, yet may benefit worker safety.

METHODS

We analyzed workers' compensation insurance firm data containing 2276 claims filed between 2008 and 2015. Injury frequency, cost, and lost time per cause, nature, and body part injured were examined qualitatively and via univariate tests. Factors associated with high cost and high duration lost time claims were modeled via multivariable logistic regression.

RESULTS

The average Thoroughbred worker claim cost $4,198 and accrued 10 days lost time, involving strikes (57% of total claims), sprains/strains (34%), and wrist/hand injuries (18%). Injuries primarily occurred on mornings (54%), weekdays (79%), and during the transition from breeding to sales (23%). Jobs with a high level of horse contact had significantly higher cost ($6,487) and higher duration lost time (16.8 days) claims, with significantly higher cost claims on the weekends ($6,471) and from the oldest workers ($7466), vs reference groups. Logistic models indicate significantly increased odds of a high-cost injury among high horse contact jobs (OR = 1.87; 95% C.I. = 1.53-2.29) and older age tertiles (1.38; 1.08-1.75; 1.70, 1.32-2.18). The odds of a high duration lost time injury are significantly increased among high horse contact jobs (1.91; 1.53-2.39) and males (1.50, 1.13-1.98), with significantly reduced odds among the most tenured workers (0.74; 0.56-0.99).

CONCLUSIONS

Our findings elucidate factors to reduce injury frequency, cost, and lost time among Thoroughbred horse farm workers.

Work-related disorders among employees of a federal public university in southern Brazil

Background

Work-related disorders have considerable impact on the health of workers at a high cost for national budgets. Yet these conditions are globally underreported, less than 8% in Brazil. Shortcomings in health policies and records hinder attempts at establishing the health profile of civil servants in Brazil, who represent 8% of the local workforce.

Objective

To establish the profile of federal civil servants with work-related disorders and relate it to diagnoses recorded in Civil Servant Work Accident Reports (CS/WAR) issued at a federal public university in southern Brazil.

Methods

We analyzed 166 CS/WAR; 79.52% corresponded to women, average age 46.46 (SD=10.06), ≥21 years in the job (34.9%), workers at the university hospital (64.46%) and medium- or technical level health care workers (45.78%). Mean duration of sick leave spells was 11.89 (SD=21.33) days. About 41.57% of CS/WAR did not provide an ICD-10 code; 82.5% of the rest corresponded to work accidents, mainly lower extremity injury (31.5%) and 17.50% to occupational diseases, most commonly low back injury and infectious diseases (17.7% each).

Conclusion

The results reinforce the need to improve the record system in public service facilities to enable strategies targeting the main health problems exhibited by this population of workers.

Factors associated with unsafe work behaviours in an Iranian petrochemical company: perspectives of workers, supervisors, and safety managers

BACKGROUND

The petrochemical industry is hazardous, in part because of the inherently dangerous nature of the work conducted, and incidents frequently result in significant financial and social losses. The most common immediate cause of incidents and injuries in this industry is unsafe worker behaviour. Identifying the factors encouraging unsafe work behaviours is the first step in taking action to discourage them. The aim of this study was to (a) explore workers', supervisors' and safety managers' attitudes and perceptions of safety in a petrochemical company in Iran, and (b) identify the factors that discourage safe work behaviours.

METHODS

A qualitative study was conducted by applying the steps described by Graneheim and Lundman (2004). Twenty participants were recruited from an Iranian petrochemical company using a multi-stage approach, with initial purposive sampling followed by snowball sampling to enhance recruitment. Individual face-to-face and semi-structured interviews were conducted to gain an in-depth understanding of factors acting as barriers to safe behaviour. The interviews were recorded and transcribed in Persian and then translated into English. Conventional content analysis was performed.

RESULTS

The main themes emerging from the interviews were: (i) poor direct safety management and supervision; (ii) unsafe workplace conditions; (iii) workers' perceptions, skills and training; and (iv) broader organisational factors.

CONCLUSIONS

The findings give insights into practical organisational measures that can be implemented by management to promote workers' commitment to safety and engage in safe behaviours in their workplace.

Findings and views on occupational safety and health teaching at universities

BACKGROUND

Young employees have often poorer occupational safety and health (OSH) skills and knowledge than older employees. Efforts should be made at different educational levels to strengthen young employees' OSH skills and knowledge.

OBJECTIVE

To analyze OSH perceptions and attitudes among university students and to examine OSH professionals' views on OSH teaching.

METHODS

This explorative study employs an iterative multi-method approach, including a paired comparison questionnaire for university students (N = 104) and OSH professionals (N = 40), an OSH questionnaire for university students (N = 130) and a Delphi survey for OSH professionals (N = 26).

RESULTS

OSH perceptions and attitudes were found to vary widely among the students and some expressed somewhat stereotypical views about OSH. The results confirm the need to improve OSH education. To that end, the study reports concrete practical ideas from OSH professionals.

CONCLUSIONS

The findings confirm the need to augment both the quality and quantity of OSH teaching at university level. Ideas are presented for future OSH teaching, along with recommendations for future studies.

Characterising the Burden of Work-Related Injuries in South Australia: A 15-Year Data Analysis

To characterise the burden of work-related injuries in South Australia, workers’ compensation claim data were obtained from SafeWork South Australia between 2000 and 2014. Descriptive analyses were performed to investigate the burden of work-related injuries by age, gender, occupation, industry, and nature and mechanism of injury. Dunn’s test was used to compare the injury costs and working days lost by industry and occupation. Ordinary linear regression was used to investigate the age-injury cost association. A total of 464,139 workers’ compensation claims were reported during the 15-year period in South Australia, with an overall rate of 4.6 claims per 100 employees, resulting in a total of 20,861,001 working days lost and AU$14.9 billion dollars of compensation payment. Between 2000 to 2014, the annual claim rates, compensation payments, working days lost, and number of work-related death reduced by 59.3, 73.8, 87.1, and 78.6 percent, respectively, while the median compensation payment increased by 67.3% from AU$968 to AU$1620. A 1-year increase in age was associated with a 2.1% (Rate Ratio, RR = 1.021, 95% CI: 1.020–1.022) increase in compensation costs and a 1.3% (RR = 1.013, 95% CI: 1.012–1.020) increase in working days lost. Work-related injury rates are declining in most sectors, however some workers, especially young male technicians and labourers in the community services industry, remain at higher risk. Challenges for workers’ health and safety include the aging labour force, vehicle incidents, and severe injuries among new and foreign-born workers.

Considerations for physical employment standards in the aging workforce

BACKGROUND

If current population and health trends continue, workplace demographics will look significantly different by the turn of the century. Organizations will no longer have a steady pipeline of younger workers and will likely need to rely on older workers to remain competitive in the global marketplace. The future multi-generational workforce will bring with it the challenge of maximizing contributions from each generation whilst at the same time addressing the health, safety and wellbeing needs of all workers.

OBJECTIVE

This review provides an insight into aging and older workers, and presents recommendations to promote worker longevity.

METHODS

This narrative review draws on evidence from 108 published sources.

RESULTS

The relationship between age and work is not simple; factors including the physical nature of the job and worker's health and fitness interact with age to either increase or decrease the potential effect of age. Evidence suggests that the issues arising from an aging workforce can be managed through polices that focus on active aging through: attitude management; flexible working and the provision of occupational health.

CONCLUSION

The integration of such interventions would require company and organizational commitment from the top down with educational programs at all levels to ensure understanding and participation.

Quantitative Risk Assessment of Seafarers' Nonfatal Injuries Due to Occupational Accidents Based on Bayesian Network Modeling

Reducing the incidence of seafarers' workplace injuries is of great importance to shipping and ship management companies. The objective of this study is to identify the important influencing factors and to build a quantitative model for the injury risk analysis aboard ships, so as to provide a decision support framework for effective injury prevention and management. Most of the previous research on seafarers' occupational accidents either adopts a qualitative approach or applies simple descriptive statistics for analyses. In this study, the advanced method of a Bayesian network (BN) is used for the predictive modeling of seafarer injuries for its interpretative power as well as predictive capacity. The modeling is data driven and based on an extensive empirical survey to collect data on seafarers' working practice and their injury records during the latest tour of duty, which could overcome the limitation of historical injury databases that mostly contain only data about the injured group instead of the entire population. Using the survey data, a BN model was developed consisting of nine major variables, including "PPE availability," "Age," and "Experience" of the seafarers, which were identified to be the most influential risk factors. The model was validated further with several tests through sensitivity analyses and logical axiom test. Finally, implementation of the result toward decision support for safety management in the global shipping industry was discussed.

Occupational safety in the construction industry

BACKGROUND

The paper is a research review focusing on occupational safety in the construction industry.

OBJECTIVE

The purpose is to present research that highlights the areas of occupational safety and risks and to identify areas where research is lacking.

METHODS

146 articles from scientific journals, mainly covering the construction industry in Europe, Canada, USA, Australia and Japan have been studied. The findings are presented under 11 categories: accident statistics; individual factors; legislation and regulations; ethical considerations; risk management; leadership, management, organization; competence; safety design; cost-benefit calculations; programs and models; and technical solutions.

RESULTS

The research is dominated by initiatives from researchers and government authorities, while the construction industry only appears as the object for the research. There is a scarcity of research on integrated systems encompassing subcontractors, as well as a lack of research with sociological perspectives on accidents. Furthermore, only a few studies have applied a gender perspective on safety in construction, i.e. there is a need of further research in this particular area.

CONCLUSIONS

A range of initiatives have been taken to increase safety in the construction industry and the initiatives are mainly reported to be successful. There are some cultural differences, but basically researchers present similar results regardless of country.

Summary of Indiana Farm Fatalities Involving Individuals 55 Years and Older—1988–2017

Agriculture has historically been one of the most hazardous of all occupations, with a variety of potential safety risks to workers and even higher risks documented for older agricultural workers. This study was undertaken to document and summarize Indiana farm work-related fatalities involving persons 55 years and older over the 30 year period from 1988 to 2017. Data were mined from the Purdue University Agricultural Safety and Health Program’s Fatality Database that dates back to the 1960s. A total of 388 fatalities involving persons 55 years and older was documented. The average age of the victims was 69.3 years old, and an overwhelming majority of the cases involved males (96.1%). The average number of deaths per year has remained fairly consistent, though it has occasionally been erratic, with an unanticipated increase in the number of documented fatalities over the period 2012–2017. There appeared to be a direct positive correlation between the level or intensity of agricultural production in a county and the frequency of fatalities. The type of fatal injury most commonly reported was crush/run-over, with 229 cases (59%). The most common agent or source of injury involved was tractors, with 157 cases (40.5%). Another noted contributing factor was the high frequency of incidents in which the victim was reported to be working alone at the time of death. Findings will be used to develop evidence-based injury prevention strategies, including the development of agricultural safety training materials and methods more relevant to older farmers. A special emphasis should be placed on reducing the risk of tractor and farm machinery overturns, especially when older, non-roll over protection structure (ROPS) equipped tractors are being operated.

Analysis of Injuries in the Ghanaian Mining Industry and Priority Areas for Research

BACKGROUND

Despite improvements in safety performance, the number and severity of mining-related injuries remain high and unacceptable, indicating that further reduction can be achieved. This study examines occupational accident statistics of the Ghanaian mining industry and identifies priority areas, warranting intervention measures and further investigations.

METHODS

A total of 202 fatal and nonfatal injury reports over a 10-year period were obtained from five mines and the Inspectorate Division of the Minerals Commission of Ghana, and they were analyzed.

RESULTS

Results of the analyses show that the involvement of mining equipment, the task being performed, the injury type, and the mechanism of injury remain as priorities. For instance, mining equipment was associated with 85% of all injuries and 90% of all fatalities, with mobile equipment, component/part, and hand tools being the leading equipment types. In addition, mechanics/repairmen, truck operators, and laborers were the most affected ones, and the most dangerous activities included maintenance, operating mobile equipment, and clean up/clearing.

CONCLUSION

Results of this analysis will enable authorities of mines to develop targeted interventions to improve their safety performance. To improve the safety of the mines, further research and prevention efforts are recommended.

Work Accidents Correlation Analysis for Construction Projects in Northern Greece 2003–2007: A Retrospective Study

Construction project related accidents are critical events and it is imperative that they are analyzed in order to understand and identify their root causes. Therefore, the present study analyzes work accidents on construction projects in northern Greece. The methodological approach firstly includes the collection of accident related data from the “Greek Work Inspection Organization”, which is followed by a descriptive analysis and corresponding codification of available data. The next step includes the creation of an appropriate database in SPSS to accommodate all relevant data and subsequent correlation analysis that aims to identify potential trends and tendencies within the accidents’ sample. The findings highlight the most frequent occurrences regarding construction work related accidents and at the same time identify correlations among the various parameters associated with them. The majority of accidents include inexperienced personnel and workers in the age range of 24–44 years old. Moreover, most accidents occur during the summer and are not fatal. Falls are by far the dominant type of accident, and as a consequence, fractures are the most frequently occurring type of injury. Finally, most accidents occur in the morning, with injuries focusing on the lower parts of the body, and in the presence of general use equipment. The current paper also identified associations among various accident characteristics. These findings could help towards reducing the number and severity of work-related accidents. Improved construction site organization, accompanied by the dedication of management towards health and safety and more frequent inspections, could decrease the number and severity of accidents.

Analysis of the severity of occupational injuries in the mining industry using a Bayesian network

OBJECTIVES

Occupational injuries are known to be the main adverse outcome of occupational accidents. The purpose of the current study was to identify control strategies to reduce the severity of occupational injuries in the mining industry using Bayesian network (BN) analysis.

METHODS

The BN structure was created using a focus group technique. Data on 425 mining accidents was collected, and the required information was extracted. The expectation-maximization algorithm was used to estimate the conditional probability tables. Belief updating was used to determine which factors had the greatest effect on severity of accidents.

RESULTS

Based on sensitivity analyses of the BN, training, type of accident, and activity type of workers were the most important factors influencing the severity of accidents. Of individual factors, workers’ experience had the strongest influence on the severity of accidents.

CONCLUSIONS

Among the examined factors, safety training was the most important factor influencing the severity of accidents. Organizations may be able to reduce the severity of occupational injuries by holding safety training courses prepared based on the activity type of workers.

Investigation into the relationship between fatal work accidents, national income, and employment rate in developed and developing countries

OBJECTIVES

Industrial advances, as a result of globalization, causes many threats to the working life. These threats are generally associated with the level of economic development of countries. While threats from industrialization are decreasing in developed countries, developing countries are still faced with these threats. Therefore, this study aims to examine the relationship between fatal work accidents (FWA), and independent variables which are national income (NI) and employment rate (ER) in a number of selected countries.

METHODS

In this study the relationship between FWA and independent variables which are NI and ER of 18 developed and developing countries and a region, between 2006 and 2015, was analyzed by applying panel data analysis.

RESULTS

According to panel data analysis, whilst a 1% increase in the NI reduces the FWA rate by 1.1%, a 1% increase in the ER results in an increase of approximately 4% in the rate of FWA.

CONCLUSIONS

As a result, there was a negative relationship between the FWA and NI growth and a positive relationship with the ER.

Making errors at work due to sleepiness or sleep problems is not confined to non-standard work hours: results of the 2016 Sleep Health Foundation national survey

Almost one-third of Australians report having made errors at work that are related to sleep issues. While there is significant literature investigating the role of sleep in workplace health and safety in shiftworking and nightwork operations, long working hours, work-family conflict, and commute times getting longer also impact day workers' sleep behaviors and opportunities. The aim of this study was to examine the relationship between sleep duration and disorders, sleep health and hygiene factors, work-related factors and errors at work in Australian workers. From a sample of 1011 Australian adults, age-adjusted binary logistic regression analyses were conducted in 512 workers who provided responses to the question "Thinking about the past three months, how many days did you make errors at work because you were too sleepy or you had a sleep problem?" A number of sleep behaviors and poor sleep hygiene factors were linked with work errors related to sleepiness or sleep problems, with age-adjusted odds of errors (confidence intervals) up to 11.6 times higher (5.4-25.1, p < 0.001) in those that snored, 7.7 (4.6-12.9) times higher in those reporting more than three sleep issues (p < 0.001), 7.0 times higher (3.4-14.8) in short (≤5 hours/night) sleepers (p < 0.021), 6.1 times higher (2.9-12.7) in those staying up later than planned most nights of the week (p< 0.001) and 2.4 times higher (1.6-3.7) in those drinking alcohol ≥3 nights/week before bed (p < 0.001). More than 40% of participants working non-standard hours reported making errors at work, and they were more likely to be young (compared to the main sample of workers) and more likely to engage in work activities in the hour before bed. Sleep factors (other than clinical sleep disorders) were associated with an increased likelihood of sleep-related work errors. Both day workers and those working non-standard hours engage in work, sleep and health behaviors that do not support good sleep health, which may be impacting safety and productivity in the workplace through increased sleepiness-related errors.

The Risk Factor of Age in Construction Accidents: Important at Present and Fundamental in the Future

Occupational accidents in the construction sector are analyzed in this study of the relation between the age of the injured worker, days off work due to the injury, and accident severity. A further aim is to establish whether accumulated fatigue during the working day and throughout the week has a similar effect on all workers, regardless of age. A total of three million four hundred and thirty-eight thousand, one hundred and forty-five (3,438,145) accidents are analyzed in this study; the total of all accidents are notified in Spain by workers from the sector over the period 1996-2015. The results confirmed a direct link between worker age and both days off work due to the injury and accident severity. They also confirmed that the workers injured in accidents in the afternoon hours were older than the workers injured in the morning hours. In consequence, the average number of days off work due to injury following an accident of the older workers was also larger and the accidents are more severe. Likewise, the workers injured on a Friday were of an older average age than those injured on a Monday. In consequence, the average number of days off work due to injury on the last day of the week was also higher and the accidents were of more severity. All the above-mentioned differences were statistically significant.

Occupational Safety and Health Among Young Workers in the Nordic Countries: A Systematic Literature Review

This review aimed to identify risk factors for occupational accidents and illnesses among young workers in the Nordic countries and to attain knowledge on specific vulnerable groups within the young working force that may need special attention. We conducted a systematic review from 1994 to 2014 using five online databases. Of the 12,528 retrieved articles, 54 met the review criteria and were quality assessed, in which data were extracted focusing on identifying occupational safety, health risk factors, and vulnerable groups among the young workers. The review shows that mechanical factors such as heavy lifting, psychosocial factors such as low control over work pace, and organizational factors such as safety climate are all associated with increased injury risk for young Nordic workers. Results show that exposures to chemical substances were associated with skin reactions, e.g., hand eczema. Heavy lifting and awkward postures were risk factors for low back pain, and high job demands were risk factors for mental health outcomes. The review identified young unskilled workers including school drop-out workers as particularly vulnerable groups when it comes to occupational accidents. In addition, apprentices and young skilled workers were found to be vulnerable to work-related illnesses. It is essential to avoid stereotyping young Nordic workers into one group using only age as a factor, as young workers are a heterogeneous group and their vulnerabilities to occupational safety and health risks are contextual. Politicians, researchers, and practitioners should account for this complexity in the education, training and organization of work, and workplace health and safety culture.

Assessing Objective and Verifiable Indicators Associated With Work-Related Stress: Validation of a Structured Checklist for the Assessment and Management of Work-Related Stress

Risk assessment represents an essential part of any successful intervention in health and safety at work. The most prominent European methodologies propose multi-method approaches for identifying the risks associated with work-related stress. Nevertheless, the most widely used method is the self-administered questionnaire. By adapting the UK Management Standards approach, the Italian National Workers Compensation Authority (INAIL) developed a checklist for the assessment of objective and verifiable indicators of work-related stress. This checklist is filled in by a steering group composed of homogenous groups of workers. Through a web-platform developed by INAIL, a considerable amount of data over the last 5 years has been collected throughout Italy. The aims of this study are to examine the psychometric properties as well as the practical validity of the checklist in a wide sample of Italian companies. The sample comprised 5,301 homogeneous groups of workers nested within 1,631 organizations. The checklist measures two main areas: (1) the organizational indicators of work-related stress (sentinel events) and (2) four and six factors related respectively to content and context of work. Multilevel and multivariate analyses revealed that the checklist shows adequate factor structure and criterion validity. Results also demonstrate that small companies and the public and healthcare sector show higher risk levels. These results support the use of the checklist as a structured and generalizable tool for assessing and monitoring the risks associated with work-related stress.

Enhancing safety competencies of young adults: A randomized field trial (RCT)

INTRODUCTION

Young workers are exposed to various occupational hazards, often with limited experience and skills. In this study, we investigated the effects of the Attitude to Work Program on the safety competencies of young workers. Based on the social cognitive theory, the intervention was developed to help young people adopt an active role in preventing occupational hazards and overcoming barriers to safe work.

METHOD

The program was implemented in eight upper secondary-level vocational schools in Finland during 2015. A total of 464 students participated in the cluster randomized field trial. Those in the intervention group (n = 229) participated in the Attitude to Work Program. During the program, students identified and practiced behavioral strategies to prevent occupational hazards. Students in the control condition (n = 235) received written material about the same safety-related topics.

RESULTS

The short-term follow-up showed that the intervention significantly increased safety preparedness and the internal safety locus of control among the students in the intervention condition in comparison to those in the control condition. Students in the intervention condition also showed reduced risk-taking attitudes relative to those in the control condition. Furthermore, those who benefited most from the program were high conscientiousness students. The sensation-seeking level or vocational track did not moderate any of the intervention effects.

CONCLUSION

The results demonstrated that safety competencies can be modified by intervention techniques based on a social-cognitive framework.

PRACTICAL IMPLICATIONS

This study provides tools for school-based safety training and future intervention development. Further research is needed to study the relationships between cognitive factors, safety behavior, and accidents.

Age, Sex, and Genetic and Environmental Effects on Unintentional Injuries in Young and Adult Twins

The aim of this study was to examine the effects of genetic and environment influences and sex on injury involvement using two sets of Finnish twin data. The younger participants were 955 twins born between 1983 and 1987, aged 20 to 24 years. The older participants were 12,428 twins born between 1930 and 1957, aged 33 to 60 years. Within-twin correlations in monozygotic and dizygotic twins suggested that genetic effects play no role in injury involvement among young twins, but do have some effect at older ages. The results indicated that environmental factors have greater importance in injury involvement than genetic factors in the younger twin data set (FT12), whereas in a middle-aged (33-60 years) twin data set, genetic effects explained about quarter of the variance in injury involvement. Sex was a strong contributing factor, with males being generally more prone to injuries than females.

Predicting the outcome of occupational accidents by CART and CHAID methods at a steel factory in Iran

Background: A large number of occupational accidents happen at steel industries in Iran. The information about these accidents is recorded by safety offices. Data mining methods are one of the suitable ways for using these databases to create useful information. Classification and regression trees (CART) and chisquare automatic interaction detection (CHAID) are two types of a decision tree which are used in data mining for creating predictions. These predictions could show characteristics of susceptible people exposed to occupational accidents. This study was aimed to predict the outcome of occupational accidents by CART and CHAID methods at a steel factory in Iran.

Design and methods: In this study, the data of 12 variables for 2127 cases of occupational injuries (including three categories of minor, severe and fatal) from 2001 to 2014 were collected. CART and CHAID algorithms in IBM SPSS Modeler version 18 were used to create decision trees and predictions.

Results: Five predictions for the outcome of occupational accidents were created for each method. The most important predictor variables for CART method included age, the cause of accident and level of education respectively. For CHAID method, age, place of accident and level of education were the most important predictor variables respectively. Furthermore the accuracy of CART and CHAID methods were 81.78% and 80.73%, respectively for predictions.

Conclusions: CART and CHAID methods can be used to predict the outcome of occupational accidents in the steel industry. Thus the rate of injuries can be reduced by using the predictions for employing preventive measures and training in the steel industry.
