Abstract

Introduction. About 82% of cases of hearing loss due to employment occur in workers in the manufacturing sector. The prevalence of hearing loss has a permanent impact that can be detected by standard threshold shift (STS). The aim of the study was to determine the relationship between individual and occupational risk factors on the proportion of STS. Methods. The research was a cross-sectional study on employees with noise exposure. The independent variables include individual factors such as age, history of hypertension, history of diabetes mellitus, smoking, body mass index, and occupational factors such as the history of chemical exposures, working period, provision of personal protective equipment (PPE), and working area. Results. The study showed that the associated risk factors were working period (OR 1.9; 95% CI 1.0-3.4), history of diabetes mellitus (OR 17; 95% CI 2.1 -146), and obesity (OR 2.4; 95% CI 1.1-5.0). The variable of history of diabetes mellitus, working period, and BMI accounted for about 12% of the proportion of STS with the main predictive value being the history of diabetes mellitus in multivariate analysis. Conclusion. The proportion of STS in the manufacturing company in the period 2018 to 2020 was 33.5%. The high proportion of STS employees may indicate the need to evaluate the hearing protection program that has been running since 2016. Suggestions for the company including improving employee protection programs, monitoring and evaluating ongoing hearing protection programs, and health programs, especially chronic diseases such as diabetes mellitus and weight loss. .

Abstract

Thyrotoxic Periodic Paralysis (TPP) is an uncommon disorder, characterized by the triad of acute hypokalemia, muscle paralysis, and thyrotoxicosis. Attacks are typically transient, last hours to days, and may be triggered by many conditions, including exposure to heat stress in both indoor and outdoor activities. Indoor workers, especially those working around furnaces, ovens, smelters, and boilers, are at a higher heat stress risk, even higher risk if they have other individual factors such as obesity, dehydration, slower heat acclimation, consume certain medications and presence of underlying diseases. A 48-year-old man presented a sudden onset weakness in all four limbs, associated with admission blood hypokalemia and thyrotoxicosis. No history of either alcohol or high carbohydrate intake consumption, infection, trauma, or heavy exercise. He has been working as a chef in the food procurement unit at a hospital for 28 years, 6 hours/day, six days/week. The results of the heat measurement at the cooking area where he works revealed that the heat stress index was 31,9º C Wet Bulb & Globe Temperature (WBGT).

Abstract

Introduction. Some manufacturing industries employ not only male workers but also female workers, who are required to undergo shift work. Given the altered eating habits as well as metabolic and endocrine profiles of shift workers, this will affect their nutritional needs. Considering that anemia that occurs in female workers is primarily nutritional anemia, this becomes a challenge in the field of occupational nutrition, especially in terms of preparing food for female workers in accordance with their nutritional needs. The aim of the study is to develop a set of FBR for female shift workers using the Linear Programming (LP) approach. Methods. Dietary data were collected in a cross-sectional survey of female shift workers (n=106) working at a textile factory in Sumedang District, West Java, Indonesia, and a market survey in two local markets. Optifood software was used for LP analysis particularly to identify problem nutrients, and nutrient-dense foods, and compare alternative FBRs. The nutrient-dense menu was developed using the identified nutrient-dense foods. Results. The problem nutrients were iron (absolute) and calcium (partial), and the remaining nutrients were still dietary inadequate. The nutrient-dense menu including iron-rich and folate-rich foods can fulfill the nutrient gap for iron from the final FBR (15% RNI of the 7% RNI). Conclusion. The inclusion of a nutrient-dense menu for the female factory workers helped to meet the nutrient gap for iron which is the absolute problem nutrient in the optimized FBR. The promotion of optimized FBR and the provision of a nutrient-dense menu should be part of the occupational nutrition program.

Abstract

Introduction. ECG is widely used for detecting cardiovascular disease in coal mine worker’s medical check-up. As the study has proven, coal mine workers have a double cardiovascular risk from their workplace hazard and their own medical risks as individuals. An early detection and risk assessment method is needed to predict ECG abnormalities in the future. This study will analyze the relationship between ECG abnormality and Framingham Risk Score on coal mine workers’. Methods. We examine ECG result from medical check-up of male coal worker during 2018 and 2021. Using Minnesota Code, we determine ECG abnormality categories in the 2021 result, then compare it with coal handling type worker and Framingham Score in 2018 as the main medical factor. Results. Among 755 male coal workers with normal ECG in 2018, 158 (20,9%) were found with ECG abnormalities in 2021. Cohort’s multivariate study shows that type of coal worker is considered a determinant, but Framingham risk score still has the highest influence (p multivariate

Abstract

Introduction. Sickness absence, which can be caused by an unhealthy lifestyle, is an important productivity parameter for the company. Therefore, there are many wellness programs developed in the workplace in an effort to improve workers’ health, fitness, and productivity. The aim of this study was to assess the effect of a physical training program for fitness improvement (VO2 max value) on sickness absence. Methods. This study was conducted by observing the results of the workers' physical training program in the chemical company during 2018, using a cohort retrospective design. SPSS Statistics version 22.0 was used for analysis, with the chi-square test for bivariate analysis and logistic regression for multivariate analysis. Results. The analysis showed that there was a significant difference between the active group (AG) and inactive group (IG) in improving fitness (adjusted RR 4.82, CI 95% 1.54-15.05) and decreasing sickness absence (adjusted RR 3.46, CI 95% 1.03- 11.57). In addition, it was found that participants with normal weight were more likely to increase fitness compared to participants with overweight or obesity (adjusted RR 3.57, 95% CI 1.09-11.64). Conclusion. Participating in a physical training program has been shown to improve fitness levels and reduce sickness absence. Normal nutritional status is more likely to have improved fitness than overweight or obese.

Abstract

Worldwide have been facing the era of dynamic life with the rapidly changing global situation for decades. This era is colored by volatility, uncertainty, complexity, and ambiguity (VUCA) situation that is aggravated by the COVID-19 pandemic. We have all experienced the VUCA situation with the COVID-19 Pandemic that has lasted over 2 years. The United Nations Development Programme (UNDP)1 report should be a common reference for dealing with situations that are not just uncertain but also called “uncertainty complexes”. So-called because its dimensions take on a new form that has never been seen before in human history. The complexity of such uncertainties includes global instability and Anthropocene inequality, the acceleration of social transformation to cope with global pressures, and widespread and intensive polarization1. The experience of facing the VUCA era and the COVID-19 Pandemic can be a provision to turn these uncertainties into expected ones. One such opportunity is made possible by keeping productive communities through the strengthening of occupational health services. Strengthening occupational health to improve the productive age group health status is a driver of productivity through efforts to prevent and control occupational and environmental health hazards2. Better occupational health services with the occupational medicine best practices are a potent strategy to overcome the raised new emerging and re-emerging potential health hazards. The shifting of the workplace and working hours across time zones are good examples of new emerging potential health hazards. The workplace shifts from the office to “working from home” or “working from anywhere” has become a common thing to implement in various sectors. Changes in the workplace lead to potential health hazards and consequent changes, including ergonomics and psycho-social health risks. The ergonomic risks of working from home and teleworking lead to an increase in work-related musculoskeletal disorders3,4. The psycho-social climate at work also changed. Studies showed psycho-social changes in the workplace during the COVID-19 Pandemic that also cause mental and emotional disorders5. From these studies, we can see that there are changes in Occupational Health risks that need to be controlled. The spread of COVID-19 in the workplace is another form of an unavoidable increase in biological risk amid efforts to defend the economic situation from uncertain threats. Controlling the spread of COVID-19 in the workplace is a good example of the importance of occupational health services6. In the VUCA era, the Occupational Health approach should be continuously improved and promptly adjusted in times to make more effective responses. Research and development of occupational medicine good practices are essential in occupational health services. Then, research results and good practices developed should be published and shared to gain broader beneficiaries. To contribute further, the Indonesian Occupational Medicine Association in collaboration with the Universitas Indonesia and Krida Wacana Christian University-Jakarta, published a journal entitled Occupational & Environmental Journal of Indonesia. We expect this journal to increase the contribution of researchers in the field of health, especially occupational medicine and the environment, through their published research.

Abstract

Background Working in shift especially night shift could alter alertness level, increase fatigue, and working accident. One of the factors that affect the circadian rhythm were melatonin. Melatonin was a hormone that regulate the wake and sleep cycle that have an impact on alertness levels. This study was aimed to find correlation between plasma melatonin and alertness level. Methods A cross-sectional study was conducted on 40 female night shift nurses. Individual characteristics were obtained by self-administered questionnaire. Plasma melatonin concentrations and alertness level was collected twice at night time (11 pm – 00 am) and at morning (7 am − 8 am). Spearman or Pearson test was used to find correlation between melatonin concentrations and Psychomotor Vigilance Test (PVT). Results Mean age was 28.4 (±4.9) years with working experience varied from 1-16 years. Plasma melatonin concentrations among female night shift nurses were higher before working hours than after duty. Range of plasma melatonin value was 10-240 pg/ml and Alertness was in the same manner with average alertness level at night was 301.2 ± 51.6 ms and 293.2± 49.7 ms at morning. There was a weak correlation between plasma melatonin concentration and alertness level difference before and after duty (r = 0.37; p = 0.016). Conclusion There was weak correlation between plasma melatonin and alertness level in night shift workers before and after duty. To Maintain alertness level reduction and melatonin secretion, night shift workers should rest at least 30 minutes during their working hours, always keep the lights on while on duty and should not work more than one shift on the same day, and providing healthy foods.

Abstract

Brominated flame retardants (BFRs) are organohalogen compounds that can inhibit fire formation and delay its spread in manufacturing materials. BFRs are known to be toxic for the environment and humans. BFRs could persist for years prolonging potential exposure and toxicity to living beings. Indonesia had begun to reduce the use, even though some of toxic BFRs are still illegally circulating. This review aims to describe some aspects of BFRs toxicity including the mechanism, its clinical manifestations, and the current possible treatments. Toxicity after BFRs exposure includes endocrine, neurodevelopmental, and genotoxicity. The toxicity is manifested into some clinical conditions such as hypothyroidism, gonadal disturbance, or neurological disorders. Currently no definitive specific treatment is available, so the treatment is focused on primary survey as well as surface decontamination with running water and gastrointestinal decontamination with activated charcoal of some dose if the ingestion is less than 1 hour.

Abstract

VIGILANCE SCREENING TOOLS IN THE WORKPLACE: SCOPING REVIEW ABSTRACT Background: Vigilance performance examination is currently used widely in many disciplines, neurophysiology, sleep medicine, psychology to its application to workers whose daily activities require prime vigilance. A more objective inspection of vigilance has not yet become a routine screening examination for workers to detect decreased vigilance as part of a fit-to-work assessment, but only in the form of research / study using a partial sampling technique. The aim is to provide an overview of vigilance screening tools in the workplace, its terminologies and how the process of maintaining quality such as calibration and validation. Methods: A literature search was independently conducted from the Pubmed database. We are looking for only articles that meet the following criteria: discussions on the terminology of vigilance, or research on workers that use vigilance examination tools, or research that develops its examination tools. Results: Three articles were found that specifically discussed the term vigilance, 30 studies on workers that used vigilance performance examination tools, and 15 studies discussing the development of these tools. The definition of vigilance is still not firmly established and has been used interchangeably and leading to confusion. Workplace research has used product-based smart devices rather than dedicated hardware, as well as a number of studies that have focused on tools development. Conclusion: Vigilance is the capability to be aware of potentially relevant or capability to be sensitive to unpredictable changes in one's environment including a quantitative and a temporal dimension. Although vigilance testing may not pinpoint the exact cause of vigilance decrement, using it as a screening tool in workplace holds great potential. Smart-device-based tools are relatively easy to obtain and inexpensive, but face enormous challenges related to calibration issues, validation issues, manufacturer's service of life, and firmware updates. It's important to consider vigilance screening tools with low-cost, portable, robust, future-proof, and easily validated with clear calibration or validation methods.
