Authors: Manar Nadia , Bouri Hicham El , Laraqui Omar , Deschamps Frédéric , Laraqui Hossini Chakib El Houssine 
Published: July 2024

Abstract

Introduction
“A good sketch is better than a long speech”. The safety poster contributes to prevention through a change in behavior by acting on the sensitivity of those who look at it. The objective was to assess the degree of perception and understanding of worker safety posters

Methods
The study involved 631 people with at least two years of seniority. Four or five INRS posters and one from the Moroccan Ministry of Health were proposed for each of the seven sectors of activity: clothing, carpentry, welding, care, slaughterhouses, electricity and tanning. The themes of the posters relate to the nature of the most frequent risks in each sector. The evaluation of the 32 posters took place in two stages: -the installation of posters according to a reasoned choice according to time and place -a questionnaire in dialectal Arabic followed by an open interview including socio-demographic and professional information, criteria for analyzing the posters (perception, understanding, appreciation, usefulness, impressions aroused, general assessment and suggested improvements).

Results and discussion
illiterate workers prefer clear, simple representations in Arabic (messages written from right to left) and not including technical terms beyond their level of understanding. Metaphors are only understood by a minority of people. Workers prefer images that are adapted and directly related to their daily activities.

Conclusion
The poster remains a preferred prevention medium, but the messages disseminated must be adapted and well understood by the target population. The socio-cultural and religious context influences the perception of the message. It is to be taken into consideration to avoid unexpected interpretations.

Published: July 2024

Abstract

Introduction
This study evaluates the effectiveness and implementation of PerfectFit@Night, an intervention to improve sleep, fatigue and recovery of night workers in healthcare.

Methods
PerfectFit@Night was implemented at twelve hospital departments that moved from the control to the intervention condition with two questionnaire measurements before and two measurements after the intervention. PerfectFit@Night lasted at least 3 months, and consisted of individual components (i.e., e-learning modules and targeted sleep coaching) and environmental elements (i.e., taking naps by using a powernap bed, healthy food provided during night shifts and a workshop on healthy rostering). The primary outcomes were sleep (night shift-related insomnia, sleep quality, sleep duration), fatigue and need for recovery. Mixed model analyses were performed to measure the outcomes over time. The implementation process was evaluated using the framework of Steckler and Linnan based on quantitative and qualitative data. Ethical approval was obtained.

Results
The first preliminary results showed that after three and six months of the intervention, the prevalence of night shift-related insomnia decreased with 11% (95% CI: -0.19, -0.04) and 13% (95% CI: -0.22, -0.05) respectively, while no effects were found for sleep quality and duration. After six months, the likelihood of more fatigue decreased (OR: 0.51, 95% CI: 0.28, 0.94) and the need for recovery decreased (β: -2.45, 95%CI: -4.86, -0.03).

Discussion
The final results of the analyses as well as the implementation of the intervention will be presented at the conference.

Conclusion
The preliminary results showed that PerfectFit@Night showed promising results for improving sleep, fatigue and recovery of night workers in healthcare.
P-525 SLEEP DEPRIVATION IN RESIDENTS. AN ACTIGRAPHIC STUDY ON ANESTHESIOLOGISTS AND OCCUPATIONAL HEALTH PHYSICIANS
Authors: Magnavita Nicola , Vacca Maria Eugenia , Meraglia Igor , Prinzio Reparata Rosa Di , Soave Paolo Maurizio , Stasio Enrico Di , Viti Giacomo 
Published: July 2024

Abstract

Introduction
Sleep deprivation poses a serious threat to doctors’ health and judgment. We sought to determine whether occupational medicine residents (OMRs) who don’t work nights have different physical and mental health than anesthesiology residents (ARs) who work only one night shift per week.

Methods
A questionnaire assessing sleep quality, sleepiness, exhaustion, occupational stress, anxiety, depression, and happiness was administered to a total of 21 ARs and 16 OMRs who were residents at a university general hospital. Residents were also asked to wear an actigraph to record their heart rate, steps taken, and time spent sleeping.

Results
The average amount of sleep time for ARs was 1 hour and 20 minutes less than for OMRs (p 0.001). Multiple regression analysis revealed that sleep quality was the major determinant of daytime sleepiness across the whole group. In addition, ARs were less happy than OMRs and were sleepier during the day.

Discussion
This study demonstrated that resident anesthesiologists who work night shifts, even if the number of such shifts is smaller than what is considered likely to alter biorhythms, sleep significantly less than their colleagues who are not engaged in night shifts and report a higher level of daytime sleepiness.

Conclusion
Given the cross-sectional nature of the study and the small sample size, these results should be interpreted with caution, but they should serve as motivation to encourage residents to practice good sleep hygiene.
P-526 THE IMPACT OF LONG WORKING HOURS AND THE USE OF WORK-RELATED COMMUNICATION DEVICES OUTSIDE REGULAR WORKING HOURS ON COMPUTER VISION SYNDROME AMONG WORKERS INTENSIVELY UTILIZING VISUAL DISPLAY TERMINALS
Authors: Shinhyeong Kim , Kang Seong-Kyu , Choi Won-Jun , Ham Seunghon 
Published: July 2024

Abstract

Introduction
Prior studies have explored psychological strain caused by work-related communication devices used beyond regular working hours. However, research on their direct physical impacts is limited. This study aimed to assess and compare the effects of long working hours and off-hours use of work-related communication devices on computer vision syndrome (CVS) symptoms among workers extensively using visual display terminals (VDTs).

Methods
This study utilized cross-sectional data from the 6th Korean Working Conditions Survey (KWCS), specifically responses from 16,304 workers using VDTs over half of work time. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using logistic regression models, adjusting for gender, age, occupation, education, and income to examine influence of work-related communication device use during off-hours or long working hours on CVS symptoms.

Results
Compared to the reference group, those using work-related communication devices off-hours without long working hours showed higher risk of CVS symptoms (OR: 1.71, 95% CI: 1.57-1.86) compared to those who worked long hours but did not use work-related communication devices during off-hours (OR: 1.36, 95% CI: 1.05-1.76). Furthermore, the group that both worked long hours and used work-related communication devices outside of regular working hours exhibited the highest OR of CVS symptoms (OR: 1.91, 95% CI: 1.65-2.22).

Conclusion
Among VDT-intensive workers, the use of work-related communication devices outside regular working hours is associated with higher risk of CVS symptoms compared to working long hours alone. This suggests that when redefining working hours, it is necessary to consider work-related communication device use outside of working hours with regular work time.
P-527 RELATIONSHIP BETWEEN FLEXIBLE WORK ARRANGEMENT, WORKING HOURS, AND SLEEP PROBLEMS AMONG PAID KOREAN WORKERS
Authors: Han Eunseun , Kang Seong-Kyu , Choi Won-Jun , Ham Seunghon 
Published: July 2024

Abstract

Introduction
Since the COVID-19 pandemic, many companies and the Korean government have promoted flexible work hours. However, there is a lack of adequate research on this topic. This study explores the effects of flexible work arrangements on sleep disorders.

Methods
We analyzed the data from the 6th Korea Working Conditions Survey involving 31,384 workers. Flexible workers were defined by self-set hours. Sleep disorders were categorized as ‘difficulty falling asleep,’ ‘frequent waking during sleep,’ and ‘waking up feeling exhausted and fatigued.’ We used chi-square tests to analyze demographic and job-related differences. A multivariate logistic regression analysis was employed to identify any potential relationship between flexible work schedules and sleep disorders.

Results
The odds ratios were as follows: 1.27 (1.11-1.45) for ‘difficulty falling asleep’, 1.34 (1.19-1.51) for ‘frequent waking during sleep’, and 1.50 (1.36-1.66) for ‘waking up feeling exhausted and fatigued’. On average, flexible workers logged 36.97 (±13.30) hours per week, while non-flexible workers worked for 38.59 (±12.35) hours per week. Additionally, flexible workers reported working at night an average of 9.06 (±8.09) days per month, slightly fewer than the 9.20 (±6.36) days reported by non-flexible workers.

Discussion
Notably, despite having shorter work hours and fewer working at night, flexible workers displayed a significantly higher likelihood of experiencing sleep problems compared to their non-flexible counterparts.

Conclusion
While flexible workers gained advantages from reduced working hours and working at night, they still faced a heightened risk of sleep disturbances. Further research is imperative to determine the causality and underlying factors responsible for this discrepancy.
P-531 PERCEIVED HEALTH IMPACT OF NIGHT WORK – A QUALITATIVE STUDY FROM THE PERSPECTIVE OF NIGHT WORKERS
Authors: Proper Karin , Loef Bette , Van Kerkhof Linda , Bosma Esmee 
Published: July 2024

Abstract

Introduction
A large fraction of the workforce works at night. While epidemiological evidence indicates that night work has a severe impact on health, insight into empirical experiences of night workers themselves is limited. Therefore, the aim of this study was to provide insight into the experiences of night workers on the impact of night work on their physical, mental, and social health. Furthermore, night workers’ views on the appreciation of night work were explored.

Methods
Data was collected through in-depth semi-structured peer-to-peer interviews (n=25). For this, 5 night workers were trained to conduct each 5 interviews with night-working colleagues (peers) about their experiences with the health consequences of night work. Transcripts were analyzed utilizing thematic analysis using inductive, iterative coding. The Consolidated Criteria for Reporting Qualitative Research (COREQ) checklist was followed.

Results
Night workers experienced reduced work capacity and daily functioning, decreased energy and fatigue, decreased sleep quality, decreased concentration and memory and emotional dysregulation, and a mental focus in preparation for the upcoming night work period. Additionally, the experiences showed social challenges, reduced need for social contact and an often-negative impact on the perceived quality of family life. Intra-personal differences were apparent in the appreciation of night work: e.g., increased daytime flexibility, a calmer working atmosphere, versus a lack of social-cultural understanding, and night work as a mandatory labor requirement.

Discussion/Conclusion
The overall experiences unfold a diverse, predominantly adverse, impact of night work on mental, physical, and social health. Furthermore, intra-personal differences in the appreciation of night work need to be contemplated conscientiously.
P-532 VITAMIN D LEVELS IN NIGHT SHIFT WORKERS AND CORRELATION WITH CANCER DISEASES
Authors: Seco Julia , Puig Marina Rovira , Maria Rosa 
Published: July 2024

Abstract

Introduction
Preliminary studies suggest that night shift work is associated with a desynchronization of metabolism of vitamin D, possibly explaining the increased risk of infection, cardiometabolic disorders, and cancer in shift workers.

Methods
This study included 49 male rotating shift workers from a car industry in Barcelona, Spain, sampled twice toward the end of a 3-week night shift (22:00-06:00 h) and a 3-week day shift (06:00-14:00 h) rotation. We collected two blood samples per worker, at the start and end of each shift. We measured levels of 25 (OH)D and 1,25 (OH)D using LC-MS/MS and applied linear mixed models to examine within-person associations between shift work and analytes’ concentrations, comparing samples taken at 06:00 h on a day and night shift, adjusting for hours of daylight.

Results
We observed lower levels of 25 (OH)D in the day shift compared to the night shift. However, levels of 1,25 (OH)D were only detectable in 67% of participants, and lower levels were observed in the night shift compared to the day shift.

Conclusion
Even though night shifts workers have been reported to have higher risk for endocrinometabolic disorders, they have slightly higher levels of 25 (OH)D. The different patterns of 25 (OH)D and specially 1,25 (OH)D need to be further studied given the inconsistency between 25 (OH)D and 1,25 (OH)D. Few studies have annalized 1,25 (OH)D, the active form of vitamin D, which may be a marker for diseases.

Published: July 2024

Abstract

Introduction
Shift work leads to sleep deprivation and sleep disruption of the immune, inflammatory and endocrine systems. Some chronic inflammatory diseases can be decompensated or exacerbated.

Aims
To study the impact of chronic inflammatory diseases on the medical fitness for work.

Methods
Retrospective cross-sectional study which had included shift workers who had consulted the Occupational Medicine Department at the Charles Nicolle Hospital over a seven-year period from January 2016 to June 2023 for a medical decision on their fitness for work.

Results
Among 243 shift workers, 9% (n=28) had chronic inflammatory diseases consulted by our department. The average age was 38 ± 7 years. The sex ratio (M/F) was 0.47. The most common professional sectors were: health (61%), industry (21%) and services (11%).The most occupied positions were: blue collar workers (25%), nurses (25%), doctors (18%).The average professional seniority was 10±6 years [1-22]. The most common chronic inflammatory diseases presented by the patients were: multiple sclerosis (22%), ankylosing spondylitis (18%), rheumatoid arthritis (11%),myopathy (11%) and scleroderma (8%). A definitive avoidance of shift work was indicated in 93% of the cases.

Conclusion
Special medical surveillance for workers with chronic inflammatory diseases by the occupational physician is necessary.

Authors: Asuncion Ronahlee 
Published: July 2024

Abstract

Introduction
The maritime industry is a critical component of the global economy, with Filipino seafarers playing a pivotal role as a skilled and dedicated workforce. However, this demanding profession comes with inherent risks and challenges, leading to various occupational injuries and disabilities.

Methods
This study examined cases related to compensation and disability claims of overseas Filipino seafarers decided by the Philippine Supreme Court from 2010 to 2020. Trends and patterns were identified to determine the common causes of accidents and injuries at sea. Secondary data were likewise used to further support the study.

Results
Findings indicate that compensation cases and disability claims among Filipino seafarers are multifaceted issues influenced by factors such as long working hours, fatigue, insufficient training, and inadequate safety measures on board vessels. Mental health-related claims emerged as a notable concern, highlighting the need for improved support and awareness in addressing psychological well-being at sea.

Discussion
The problem in compensation cases and disability claims of Filipino seafarers is complex and involves several challenges that hinder their access to fair and timely compensation for work-related injuries and disabilities. Seafarers seeking redress are faced with delayed processing, insufficient training and safety measures, mental health concerns, and jurisdictional challenges among others.

Conclusion
Addressing these problems requires collaborative efforts among relevant stakeholders, including government agencies, shipping companies, labor unions, and international organizations. By improving regulations, streamlining processes, enhancing safety measures, and providing better support for seafarers’ well-being, it is possible to ensure fair compensation and improved outcomes for Filipino seafarers facing work-related injuries and disabilities.
O-355 DETERMINANTS OF OCCUPATIONAL INJURIES AMONG INFORMAL CONSTRUCTION ARTISANS IN OSUN STATE NIGERIA. A MIXED-METHODS SURVEY OF CARPENTERS AND BRICKLAYERS
Authors: Ojo Temitope , Naicker Nisha 
Published: July 2024

Abstract

Introduction
Occupational injuries (OI) remains a global health issue, claiming approximately 1000 lives daily. This study assessed the factors influencing OIs among carpenters and bricklayers who are informal artisans in Nigeria.

Methods
This mixed-methods survey was conducted in Osun state Nigeria. The quantitative component entailed a comparative cross-sectional study of 421 bricklayers and 425 carpenters. Information on socio-demographics and, OI prevalence was obtained using a semi structured questionnaire. The qualitative aspect comprised 12 focus group discussions among artisans.

Results
All respondents were male. The mean age was 51.3.7±14.7 years for bricklayers and 50.0±11.5 years for carpenters. The 3-month. prevalence of OI was 39.9% for bricklayers and 51.8% for carpenters. Factors associated with OI among bricklayers included being aged 20-39 years (AOR:6.2, 95%CI:2.7-14.2) and 40-59 years (AOR:2.7, 95%CI:1.4-5.4), earning less than N50,000 ($67) monthly (OR:2.6, 95%CI:1.3-5.5), earning N50,000-N100,000 ($67-$133) monthly (AOR:2.8, 95% CI: 1.3-5.9), and handling ≥200kg per day at work (AOR:1.9, 95% CI:1.1-3.2). For carpenters, factors associated with OI were being aged 20-39 years (AOR:3.7, 95% CI:1.6-8.6), age 40-59 years (AOR:1.9, 95%CI:1.02-3.5), and handling 100-199kg per day at work (AOR:2.1, 95%CI:1.1-3.9). FGD findings revealed that use of substandard building materials, poor use of personal protective equipment and working at heights may predispose to OIs.

Discussion and conclusion
The burden of OI is high among informal construction artisans in Nigeria. Safety interventions should target persons &lt; 60 years, those handling heavy weights at work (&gt;100kg) and bricklayers earning &lt; N100,000 ($133) monthly. Emphasis should also be placed on use of safety equipment and ensuring standards of building materials.

Authors: Samuneva-Zhelyabova Marina , Spiroski Ivan , Markova Rositsa 
Published: July 2024

Abstract

Introduction
Technological processes in the construction industry accompanied by heavy construction equipment are risks for occupational accidents and work-related diseases. The aim of the present study is to set up the correlation between risk factors and the incidence of socially significant diseases.

Materials and methods
For the purpose of the study 362 workers in the construction sector were surveyed. The information obtained was processed using a descriptive and analytical methods. The descriptive statistics and analysis of relationships between individual statistical series were conducted throughout the Pearson 2 test for attributive data, i.e. T--test and Pearson correlation test for numerical series.

Results
All surveyed participants were Male and the mean age of the respondents was 51.1±9.3 years. The working experience of the position held was 26.1±8.2 years. The distribution by job title shows that 278 of the respondents were construction workers and those working in administration were 84. A correlation was established - the higher the prevalence of cardiovascular diseases and arterial hypertension diagnosed by a physician, the higher the blood pressure values among registered construction workers

Discussion
The most common risk factors for the respondents from both groups indicated were the cardiovascular diseases with the possible key role of the work environment factors in the multicausal etiology of the disease.

Conclusion
Measures need to be taken at all levels to reduce cardiovascular diseases among construction workers such as: introducing health promotion programmes aimed at eradicating harmful habits and conducting regular preventive check-ups.
P-547 FATAL OCCUPATIONAL ACCIDENTS IN THE PRIVATE SECTOR IN TUNISIA (2020-2021)
Authors: Houria Amira , Bani Meja , Hamdouni Mongi 
Published: July 2024

Abstract

Introduction
fatal occupational accidents (foas), due to their harmful consequences on both workers and the country’s economy, are a current issue that requires significant attention.

Methods
this was a retrospective study, including all cases of foas reported to the regional offices of the national health insurance fund over a 2-year period (2020-2021).

Results and discussion
we collected 161 cases during the study period, with an average annual rate of 80 accidents and a monthly rate of 6 accidents. A majority of the cases were male (95.65%), with an average age of 44 years and an average work tenure of 6 years, of which 45.3% had less than one year of experience. Unskilled workers were the most affected (65.2%), especially in the construction (27%) and electrical industry and transportation sectors, which were identified as high-risk sectors for foas. Falls from heights were the most common type of accident (21.6%), followed by simple impacts and/or impacts from moving objects (16%) and electrocutions (11.8%). Non-traumatic fatal occupational accidents accounted for 18.6% of cases, with polytrauma in 60.86% of cases.

Conclusion
The consequences of FOAs warrant consideration in terms of occupational risk management and the promotion of prevention involving all stakeholders, including employers, employees, occupational physicians, insurers, and legislators.
