Abstract

Introduction
The aim of this study was to investigate the combined effect of low cardiorespiratory fitness and high physical workload on disability pension (DP) due to musculoskeletal disorders (MSD: s).

Methods
279 353 men were followed regarding MSD DP between 2006-2020, ages 45-64 at the start of follow up. Cardiorespiratory fitness was assessed during military conscription, using an ergometer bicycle test, and physical workload was based on a job-exposure matrix (JEM) linked to occupational titles in 2005. DP cases were taken from register data. Cox regression models estimated the combined association with MSD DP.

Results
Workers with the combination of the highest level of physical workload and the lowest level of cardiorespiratory fitness showed the highest risk (HR 6.21 95% CI 4.93-7.83); higher than would be expected from adding the effects of the single exposures After adjustment for age, birth year, childhood socioeconomic position, cognitive ability, body mass index, previous unemployment, and education (fully adjusted model), the association attenuated but remained statistically significant (HR 2.39 95% CI 1.87-3.07).

Discussion
Preventive measures targeting both increased cardiorespiratory fitness and a reduced physical workload could help reduce the risk of MSD DP.

Conclusion
The combination of low cardiorespiratory fitness and high physical workload was associated with a higher risk of MSD DP than would be expected from adding the effects of the single exposures.

Abstract

Introduction
Occupational exposure to formaldehyde (FA) has been linked to hematopoietic and nasopharyngeal cancers.

Methods
To further evaluate the biological effects of exposure to FA in humans, we used comprehensive untargeted liquid chromatography with high resolution mass spectrometry (LC-HRMS) to characterize the plasma metabolome of workers (n=43) exposed to relatively high levels of FA [median 8-h time-weighted air level average exposure: 1.3 parts-per-million (ppm) of air] and comparable controls (n=51). Metabolite features associated with FA exposure were identified using a metabolome- wide association study that tested for relationships between metabolite feature intensity and occupational exposure to FA.

Results and discussion
Metabolic pathway enrichment analysis highlighted multiple pathways associated with FA exposure, with significant changes in the carnitine shuttle and in arachidonic acid, fatty acid, nucleic acid, amino acid, steroid, and prostaglandin metabolism. These results suggest possible changes or perturbations from FA exposure in fatty acid uptake, oxidative stress, and pathways related to mitochondrial dysfunction, immune system disorders, and altered cell proliferation, several of which are consistent with previous experimental and human studies. Taken together, our results suggest that occupational exposure to FA was associated with alterations in a number of systemic metabolic processes.

Conclusion
Further study is needed with larger sample sizes to replicate and extend these findings.

Abstract

Introduction
In Japan, a state of emergency was declared four times until December 2022 due to the Covid-19 epidemic. The purpose of this study was to examine the changes in anthropometry and blood test parameters related to lifestyle-related diseases after the Covid-19 outbreak.

Methods
A longitudinal study was employed. A total of 1,198,557 employee who underwent health check-ups at Uguisudani Medical Center from April 1, 2016 to March 31, 2022 in Tokyo, Japan, were analyzed. Data included BMI, waist circumference (WC), systolic and diastolic blood pressure (SBP/DBP), total cholesterol (TC), triglycerides; triacylglycerol (TG), and low- and high-density lipoprotein cholesterol (LDL, HDL), fasting blood glucose (FBG), and uric acid (UA) levels. Descriptive statistics was performed separately for males and females to assess the temporal changes. Ethical approval for this study was obtained from the Dokkyo Medical University Ethics Committee.

Results
Comparing pre-2019 and 2020, SBP/DPB, TC, TG, and LDL increased more than normal and HDL decreased for both men and women after the Covid-19 outbreak. However, comparing data from 2020 and 2021, there is little change or slight improvement.

Discussion and conclusion
The greater deterioration in health check-up results in 2020 was likely due to lifestyle changes, including a decrease in outdoor activity and exercise habits due to voluntary restraint in personal activities. Modest government measures eased the subsequent refraining from personal activities, and the health examination results in 2022 did not deteriorate further. This suggests that social changes due to Covid-19 have a limited impact on health outcomes in Japan.

Published: July 2024

Abstract

Introduction
The assessment of fitness for work aims at evaluating a worker’s capacity to perform a job with or without minimal risk, immediate or future, to his health and safety. After a medical evaluation, the worker will be considered as “Fit”, “Unfit” or “Conditionally fit” if the workplace or tasks call for temporary or permanent adjustments. This study aims at understanding which conditions most commonly require adjustments at the workplace.

Methods
A retrospective cross-sectional analysis focusing on healthcare professionals considered “Conditionally fit” from 2022 to 2023.

Results
From a total of 237 healthcare professionals considered “Conditionally fit”, 86% were women and the majority were hospital aides (44,3%) and nurses (35,4%). Sixty-five percent resulted mainly from musculoskeletal injuries, 13,5% from mental health disorders, 5,9% related to immunosuppression and 3,8% to oncologic disorders.

Discussion
Musculoskeletal injuries continue to be the primary health concern among healthcare professionals, which can be mainly attributed to their exposure to extreme postures and to the growing number of obese patients. Following closely are mental health disorders, which can be a consequence of elevated levels of workplace stress, burnout and demands of shift and night work. Lastly, due to their natural illnesses, immunosuppressed and oncologic workers require a reduction of exposure to biological risks.

Conclusion
Our analysis reflects once again the high prevalence of musculoskeletal and mental health disorders. There is still a necessity of preventive and effective measures to eliminate or minimize the risk, to implement engineering and administrative controls and to improve personal protective equipment.

Published: July 2024

Abstract

Introduction
Insufficient socio-technical and organizational leeways (STOL) are considered as a risk factor for musculoskeletal disorders (MSD) in the ergonomic literature. However, no epidemiological study has investigated this concept. The aim was to identify proxy questions indicating the dimensions of STOL (macro-dimensions of operational leeway in the work situation) available in the work environment and perceived by workers in order to include them in epidemiological occupational health questionnaires.

Methods
The Technique for Research of Information by Animation of a Group of Experts (TRIAGE) was implemented to select questions. Seventy-five questions from French epidemiological questionnaires close to the concept of STOL were identified by an interdisciplinary working group (statistics, ergonomics, epidemiology, occupational medicine). An individual consultation and a group consultation phases followed one another. Twelve experts were solicited individually to express their agreement level, via an online questionnaire, to consider the questions as proxy of STOL. Questions not retained were discussed collectively in two online meetings between the nine experts available, and experts voted via an anonymous online questionnaire to retain (or not) each question.

Results
In total, 42 questions were retained as proxy of STOL: 23 in the individual consultation phase (agreement &gt;83,3%) and 19 in the group consultation phase (agreement &gt;85,7%). The proxy questions will be presented at the congress.

Discussion
To our knowledge, there is no epidemiological study on the association between STOL and MSD while this concept would be of relevance for MSD prevention.

Conclusion
The proxy questions could be useful for epidemiological research and for ergonomic interventions.

Abstract

Introduction
Police officers are regularly exposed to psycho-trauma during routine police work. During the attack, many police officers intervened until the terrorist was neutralized. As there was no process in place to monitor so many police officers medically over such a short period of time, it was decided to set up an epidemiological study within the occupational health department. Police operational support psychologists made themselves available to the officers, but not all of them were consulted. Our aim was to identify officers with post-traumatic stress disorder, depression, suicide risk and to offer them treatment if they had not been consulted themselves.

Methods
Three months after the attack, an online questionnaire was sent to police officers. Questions covered socio-demographic data, occupation, degree of exposure, sleep during the week following the attack, PTSD (PCL-5), depression (PHQ9), and suicidal ideation (Yes/no questions). Of the 475 police respondents, 263 had been exposed to the attack (182 directly) and 212 had not.

Results
The prevalence of partial and complete PTSD in the exposed group was 12.6% and 6.6% respectively. The prevalence of depression was 11.5%. A higher risk of PTSD was present in directly exposed police officers (OR=2.98[1.10-8.12]p=0.03), but not of depression (OR=0.40[0.10-1.10] p=0.08). Conversely, sleep deprivation in the week following the attack was associated with a higher rate of depression (OR=7.92[2.40-26.5]p&lt;0.001) and not PTSD (OR=2.18[0.81-5.91]p=0.13).

Discussion and conclusion
As police officers are exposed to a non-negligible risk of PTSD, it is necessary to set up an organization in the occupational health department to identify these officers, with a particular focus on those directly exposed.

Abstract

Introduction
The tire manufacturing industry is widespread globally, with a high demand for labor. Employees engage in physically demanding work to produce rubber tires. The study was conducted with an aim to assess selected morbidities among tire manufacturing workers in India and recommend measures.

Methods
The retrospective record-based cross-sectional study was conducted over 3 months. Data was obtained from periodic medical examination of employees and was analyzed using SPSS version 23, and Chi-square test was used to assess associations between qualitative variables.

Results
Among the 885 workers screened, all were males. It was observed that 8.1% had obesity with a BMI of 30 and above and 19.6% had deranged blood sugars with random blood sugar &gt;200mg/dl, 6.1% had far vision defect and 15.5% had near vision defect, 6.3% workers had anemia with hemoglobin less than 11 gm%, 17.4% had deranged lipid profile and 12% had abnormal spirometry findings, 3.2% had abnormal audiometry tests, 4% workers were detected with uric acid crystals, 4% worker was detected with calcium oxalate crystals and 11.1% worker had glucose in urine.

Discussion
Tire industry workers suffer from various health problems notably, hematological and auditory and visual impairments, pulmonary function abnormalities and also non-communicable diseases.

Conclusion
This study stresses the need for regular health surveillance of workers to detect any deviations from heath along with information, instruction and training on use of appropriate PPE. Lifestyle modifications such as exercise and healthy diet should be inculcated amongst the workers to prevent non-communicable diseases along with good hydration during working periods.
P-129 EPIDEMIOLOGICAL STUDY IN HEALTHCARE WORKERS ON PRIVAT HOSPITAL IN BRASÍLIA BETWEEN JANUARY 2019 AND DECEMBER 2022
Authors: Cavalcanti Celso , Pinke Rodolfo 
Published: July 2024

Abstract

Introduction
This study aims to show the variations in the most important pathologies in four years of observation of health workers at a private hospital in Brasília.

Methods
The database of medical certificates presented by sick workers was organized in a table relating the CID groups, number of workers and days absent classified from 2019 to 2022. The frequency was testing normality by Shapiro-Wilk and then applying the Wilcoxon test, we found no significant statistical differences and we used the IBM SPSS Statistics version 25 program.

Results
We observed 3,946 health workers with 23,796 days of work absent and a frequency of 6 days per worker. The ICDs with the highest number of days absent were in descending order: B, M, S, Z, F, J and U. The highest frequencies were F and S. We observed that of the respiratory diseases with ICDs B, J and U combined they represent 44 % of total days absent.

Discussion
Respiratory diseases were ranked fifth in 2019, however with the emergence of the COVID pandemic it became more relevant with ICD U and B. Even with the immunization for COVID of almost all hospital workers, we still observed the strong influence of ICD B and U. ICD F had the highest frequency in this group.

Conclusion
The COVID virus and its mutations continued to influence worker absences and maintaining the worker outreach program is important for controlling and reducing respiratory illnesses. After the four waves of COVID, we observed that the mental health of workers was affected.

Published: July 2024

Abstract

Introduction
This study investigates whether mental disorders in childhood impacts i) high school drop-out during adolescence, and ii) NEET in their early twenties. Secondly, it assesses to what extent the effect of mental disorders on NEET is mediated by high school drop-out and the effect of the mental health and employment status of the parents.

Methods
Longitudinal nationwide register data from Statistics Netherlands were used for persons born in 1994. These included medication prescription for mental disorders (ages 12-15 years), high school dropout (ages 16-19 years) and participation in education or employment (NEET, age 21-26 years). Additionally, mental health and employment status of the parents will be included, these results will follow later. Linear and logistic regression analyses were performed on the association between mental disorders and NEET and between mental disorders and having a high school dropout period. Causal mediation analysis was used to assess to what extent the effect of mental disorders on NEET could be reduced by eliminating high school dropout.

Results
Taking medication for mental disorders was strongly associated with a longer NEET period (β 17.4, 95% CI 16.7;18.0) and also increased the risk of having a high school dropout period (OR 2.3). Having a high school dropout period significantly contributes to having a longer NEET period among persons with mental disorders (NIE 1.5, 95% CI 1.4;1.7).

Conclusion
Mental disorders in childhood are strongly associated with a longer NEET period in early adulthood, which can be reduced by preventing high school dropout.

Published: July 2024

Abstract

Introduction
Elevated blood pressure (BP) is related to lifestyles and is prevalent among firefighters, but evidence is limited to non-Asian populations. We validated a revised 7-item Mediterranean-diet-based lifestyle score (MEDI-Lifestyle) and utilized it to examine Taiwanese firefighters’ lifestyle and its association with BP.

Methods
A cohort-based online survey investigated 548 firefighters in Tainan, Taiwan during mid-May 2023. After excluding non-adults, those with missing essential information, and outliers, we analyzed 486 (88.7%) participants. Retests were done five weeks later in a subsample (n=22). We calculated the test-retest intraclass correlation coefficient (ICC) for reliability and the Spearman’s correlation coefficient (ρ) between the Insomnia Severity Index (ISI) and MEDI-Lifestyle for concurrent validity. Multiple linear regression models were built to examine the associations between the MEDI-Lifestyle and BPs. Participants’ BPs were measured following a standard protocol. The R software 4.3.1 and SAS 9.4 were used for analyses. National Yang Ming Chiao Tung University’s Institutional Review Board approved the study (NYCU112057AE).

Results
The test-retest ICC was 0.44 (95% CI: 0.035–0.72). The MEDI-Lifestyle was negatively correlated with the ISI (ρ= -0.208, P&lt; 0.001). After multivariable adjustment, a one-point increment in MEDI-Lifestyle was associated with 1.3 and 1.4 mmHg decrement in systolic and diastolic BP, respectively (both P&lt; 0.05).

Discussion
Using the MEDI-Lifestyle to assess Asian firefighters’ lifestyle and its association with BPs is a valid and novel approach. Future research is warranted to establish a causal relationship between MEDI-Lifestyle and BP.

Conclusion
With fair reliability and validity, the MEDI-Lifestyle, which is negatively associated with BP, is applicable to Taiwanese firefighters.
O-087 FACILITATORS AND BARRIERS FOR THE IMPLEMENTATION OF PREVENTIVE TASKS BY OCCUPATIONAL PHYSICIANS AND STRATEGIES TO OVERCOME THESE – AN IMPLEMENTATION MAPPING APPROACH
Authors: Pees Suzanne Orhan , Van Oostrom Sandra , Schaafsma Frederieke , Proper Karin 
Published: July 2024

Abstract

Introduction
Work-related mental health problems are a major and growing public and occupational health issue. This underlines the need for prevention, in which occupational physicians have a key role. However, implementation of preventive tasks can still improve. The aim of this study is therefore to identify facilitators and barriers for the implementation of preventive tasks by occupational physicians and to develop strategies to support the implementation.

Methods
This study follows the systematic approach of Implementation Mapping. First, a literature search was performed to identify facilitators and barriers. These factors were clustered in nine themes and scored by stakeholders on the aspects of importance and changeability. In addition, the stakeholders proposed strategies to counteract the barriers, which were scored on the aspects of expected impact and feasibility.

Results
The most important barriers are: insufficient knowledge about prevention among employees and employers, insufficient multidisciplinary collaboration and insufficient knowledge and skills of the occupational physician. Facilitators for the execution of prevention are: combining preventive tasks with other tasks and delegating preparatory tasks to other professionals involved in the organization, such as the prevention officer. Strategies proposed for occupational physicians to overcome the barriers are visiting the workplace to increase visibility, including multidisciplinary collaboration in contracts with OHS and highlighting best practices with regard to prevention.

Discussion and conclusion
These findings will be used to develop a peer support based intervention for occupational physicians, which will be evaluated in a cluster randomized controlled trial.

Abstract

Introduction
Occupational skin injuries (OSI) are frequent and underestimated. Working in manufacturing settings is particularly prone to this type of accident. To develop appropriate prevention strategies, risk assessment is essential. The aim of our study is to describe the particularities of OSI, analyze them and propose appropriate prevention actions.

Methods
We carried out a cross-sectional study in a pastry-making factory. Quantitative analysis of OSI was performed by calculating the frequency rate FR, the frequency index FI and the severity rate SR, main indicators of work-related injuries. Qualitative analysis was conducted using the causal-tree method.

Results
The study included 47 employees who had been victims of OSI. The average age was 38.3±10 years. Average job seniority was 12.7±7.8 years, and 72.3% of the individuals occupied manual tasks. Among 52 recorded OSI, wounds counted for 63.5% and burns for 36.5%. Hands were most affected (86.5%). Four cases of second-degree burns were recorded, covering an average body surface of 1.75%. The FR, IF and SR indicators were 3195, 36.2 and 25.9, respectively. The causal-tress analysis enabled us to retrace the deeper facts that contributed to their occurrence.

Discussion
Agri-food industries are particularly known for the use of heat sources and handling sharp utensils. This suggests that OSI are frequent in this sector. In Tunisia, among reported occupational injuries, wounds and burns are the most frequent, and hands are usually the most affected site.

Conclusion
OSI in the agri-food sector require greater attention. Rigorous analysis will enable targeted prevention through technical and organizational measures, employee training and information
