Workers In Various Occupations Research Articles

Relationship between working hours and sleep quality with consideration to effect modification by work style: a community-based cross-sectional study.

Although longer working hours are associated with lower sleep quality, it is still necessary to work a certain number of hours to make a living. In this study, we investigated the relationship between working hours and sleep quality in a community setting. We then explored how to manage work style while maintaining the sleep quality of workers without markedly reducing working hours. 4388 day-time workers in various occupations living in Ota ward in Tokyo were included in the analysis. The relationship between working hours and sleep quality measured by the Athens Insomnia Scale was examined by ANOVA and linear regression models. Effect modification by work style (work end time, shift in working start and end time, current work from home status, change in work place) on the relationship between working hours and sleep quality was investigated by multivariate linear regression models. Longer working hours were significantly associated with lower sleep quality. The magnitude of the relationship between long working hours and low sleep quality was significantly larger when work end time was later (p for trend of interaction < 0.01) and when working start and end time were shifted later (vs no change, p for interaction = 0.03). The relationship was marginally greater when the proportion of work from home was increased (vs no change, p for interaction = 0.07). A relationship between longer working hours and lower sleep quality was observed among workers. Leaving work earlier or optimizing the work environment at home may diminish the adverse effect of long working hours on sleep quality.

Work-related musculoskeletal disorders: prevalence, associated factors, and impact on quality of life among kitchen workers in hospitality industry, Bahir Dar City, Northwest Ethiopia, 2023.

Work-related musculoskeletal disorders (WMSDs) are considered major public health problems globally, deteriorating the quality of life of workers in various occupations. Kitchen work is reported as among the occupations most prone to these maladies. Nevertheless, prevalence of WMSDs, contributing factors, and impacts on the quality of life of hospitality industry kitchen workers are insufficiently documented in Ethiopia. Therefore, this study aimed to assess the prevalence of WMSDs, their associated factors, and impact on the quality of life of hospitality industry kitchen workers in Bahir Dar city, Ethiopia. An institution-based, cross-sectional study was conducted from 17 April to 17 May 2023. A total of 422 participants were included using a simple random sampling technique. WMSDs were evaluated using an interviewer-administered Nordic standardized questionnaire. The short form-36 questionnaire was used to assess quality of life. The data were collected using the Kobo tool box. SPSS version 26 software was used to perform both bivariable and multivariable binary logistic regression analyses. Independent t-tests were used to show the impact of WMSDs on quality of life scales across groups with and without WMSD symptoms. In this study, the response rate was 98.34% (n = 415). The 1-year prevalence of WMSDs among kitchen workers was 82.7% [95% CI: (79.1, 86.3)]. Age group between 30 and 39 years [AOR: 2.81; 95% CI: (1.46-5.41)], job dissatisfaction [AOR: 2.45; 95% CI: (1.34-4.45)], anxiety [AOR: 2.26; 95% CI: (1.12-4.52)], prolonged standing [AOR: 3.81; 95% CI: (1.58-9.17)], and arm overreaching [AOR: 2.43; 95% CI: (1.34-4.41)] were significantly associated factors with work-related musculoskeletal disorders. Work-related musculoskeletal disorders had a significant impact on all quality of life dimensions, in which the mean SF-36 scores of participants with WMSDs were lower than those of their non-WMSD counterparts. This study revealed that the prevalence of WMSDs was relatively high. Age between 30 and 39 years, job dissatisfaction, anxiety, prolonged standing, and arm overreaching were identified as significant determinants of WMSDs among kitchen workers in hospitality industries. The presence of one or multiple WMSDs, in turn, is associated with worse quality of life dimensions of individuals.

Status of Occupational Health and Safety in Nepal: Current Scenario and Strategies for Improvement

Occupational health is a vital aspect of public health that aims to ensure the well-being of workers in various occupations. It encompasses multiple academic fields, such as occupational medicine, nursing, ergonomics, psychology, hygiene, and safety. Despite global efforts to improve occupational health, access to occupational health and safety (OHS) services remains low in many countries, including South Africa, Zimbabwe, Zambia, Botswana, China, and Nepal. This review paper was conducted through an extensive literature review. Databases such as Science Direct, Springer, NepJol, PubMed, and Google Scholar were searched to access a wide range of scholarly articles, research papers, and reports. The findings reveal that occupational workers face various hazards, including exposure to infectious diseases, radiation, hazardous chemicals, noise, and psychosocial risks. In Nepal, workers in industries such as agriculture, construction, and brick manufacturing are particularly vulnerable to these hazards. Lack of proper safety measures, inadequate access to clean drinking water and sanitation, child labor, and physical strain contribute to the high incidence of work-related diseases and injuries among workers. The study also highlights the policies and initiatives undertaken by the government of Nepal to improve occupational health and safety, including the Labor Act of 1992, the Occupational Safety and Health Project, and the Nepal National Building Code. The study emphasizes the urgent need to improve occupational health and safety conditions in Nepal. It highlights the importance of implementing preventive measures, raising awareness, providing training and education, and establishing standards to protect the health and well-being of workers.

Personal exposure to radiofrequency electromagnetic fields in various occupations in Spain and France

BackgroundA preliminary job-exposure matrix (JEM) for radiofrequency electromagnetic fields (RF-EMF) was created based on self-reported occupational information from a multi-country population-based study of approximately 10,000 participants combined with available measurement data compiled in a source-exposure matrix (spot measurements). In order to address the limited personal occupational RF-EMF measurement data available in the literature, we performed a measurement campaign among workers in various occupations in Spain and France. MethodsPersonal full-shift measurements were conducted using RadMan 2XT™ (Narda) devices. A worker diary was used to capture information on occupational and background sources of RF exposure during the shift. Inclusion of occupations to be measured was initially based on exposure prevalence and level information in the preliminary JEM and expert judgment. ResultsPersonal full-shift measurements were conducted among 333 workers representing 46 ISCO88 occupations. Exposure to electric (E) and magnetic (H) fields was infrequent with >99% of measurements below the detection limit of the device (≥1% of the 1998 ICNIRP standards). A total of 50.2% and 77.2% of workers were ever exposed to E and H fields respectively (having at least one recorded 1-second measurement above the detection limit). Workers in elementary occupations, technicians and associate professionals, plant and machine operators and assemblers had somewhat greater numbers of measurements above the detection limit, higher maximum values and longer exposure durations. A small proportion of measurements were ≥100% of the standards, though these exceedances were brief (generally a few seconds in duration). Female workers and workers reporting use of any RF-EMF emitting source were more likely to have a measured exposure to E and H fields. ConclusionWe conducted personal RF-EMF measurements among workers in various occupations in Spain and France. Overall, RF-EMF exposure ≥1 % ICNIRP was infrequent, despite some intermittent exposures ≥100% observed among workers in some occupations.

Green Skills in the European Labour Markets

This paper aims at exploring the significance of green skills in the European labour market, highlighting their importance for workers in various occupations and fields of the European economy. The European labour market has undergone several significant changes over the past decade as a result of the increased demand for sustainable practices and the need for a green transition. New strategies and policies have lavishly evolved to address the challenges related to climate change and environmental decay. The concept of green skills has thus emerged, referring to the skills, knowledge and competences required for working in a sustainable and environmentally friendly way. In this context, this paper analyses specific aspects of the economic, environmental, and social impact of green skills from the point of view of an increasing demand for green skills in various occupations. It finally examines the benefits of having a well-trained workforce equipped with green skills as well as the level of responsiveness for certain EU member states towards the need to address existential challenges of the green transition.

Hustle: Experiences of making work ‘work’ for non-standard and precariously employed workers in NYC

Abstract Background Precarious and non-standard employment (NSE) has negative implications for workers’ health. As part of a six-country comparative mixed methods case study, this research explores US-based workers’ experiences in NSE and its influences on their health and well-being in a context of weak labor regulations and social welfare programs. Methods To understand US policy context, we analyzed country-level labor regulatory and social protection frameworks using 2019 Organization for Economic Cooperation and Development data. To understand workers’ experiences, we conducted in-depth interviews with NSE workers in various occupations in New York City (N = 40) between January and May 2021. We recruited and screened eligibility via Facebook advertisements and an online questionnaire, respectively. We used deductive and inductive thematic analysis for interview data. Results With heavy reliance on market competition in the US, minimal state regulation and flexible labor markets create less secure employment along with limited government-funded social supports. Workers’ experiences center on the Hustle, i.e., figuring out how to make NSE work for them and their families. They lack healthcare coverage and have low expectations of other supportive employment and social protections (e.g., paid leave). While NSE payoffs (e.g., perceived flexibility) were common for most, almost all experience NSE tradeoffs (e.g., job insecurity and instability) that create stress and overwork, negatively implicating overall health and well-being. These impacts differ by access to resources associated with social location (e.g., immigration status). COVID-19 exacerbated these experiences. Discussion Low expectations of supportive policies of US workers in NSE are linked to the individualized hustle, as they attempt to counter NSE tradeoffs often relying on family to fill those gaps. Over-reliance on privatization for social supports such as healthcare coverage can be detrimental to workers’ health. Key messages

Fatigue and its associated risk factors among shift workers: A systematic review

AbstractShift workers in various occupations are at risk of getting fatigued due to the nature of their work. This study provides a systematic outline of the occurrence of fatigue and its risk factors for shift workers in various industries worldwide within the decade. A systematic review from five literature databases was searched using three keywords, namely fatigue, shift work, and shift workers. The Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines were used, and two reviewers reviewed the titles separately, picked abstracts, full texts, and checked their quality based on the predefined criteria. The search strategy for initial literature resulted in 3829 potential articles, but only 29 articles were included in this review. Differences in the definition of fatigue and the assessment method used were found to have resulted in the different prevalence of fatigue from various studied occupations. Eighteen risk factors divided into sociodemographic, work‐related, and outside of work factors were found. This review demonstrates that fatigue is a significant issue for shift workers with various risk factors involved. Future research in regard to the epidemiology of fatigue should focus on related risk factors. Thus, an appropriate intervention program to reduce fatigue could be developed and executed effectively towards lowering fatigue cases among shift workers.

Risk factors for non communicable diseases among transport and security personnel of a health sciences university in coastal Karnataka

Background: Non communicable diseases (NCDs) are on the rise among workers in various occupations resulting in morbidity and mortality. This study was conducted to assess the various risk factors and associated socio-demographic factors among the security and transport personnel working in a health sciences university in Mangaluru.Methods: It was a cross-sectional study conducted among all the security and transport personnel. Questionnaire based on WHO-STEPS approach was used. Blood pressure (BP) measurements were recorded.Results: Total 167 study participants were enrolled; 57.5% were security and rest were transport personnel. Physical activity was perceived as light by 63.5% participants. Current smokers constituted to 26% and 33.5% consumed alcohol in past 12 months. Eighteen percent of them top salted their food. Among participants who were apparently healthy, 12.5% and 23.4% had raised systolic and diastolic BP. Associations between the areas of residence (p=0.004) and type of occupation (p&lt;0.001) were found to be significant.Conclusions: Prevalence of risk factors of NCDs was high among study participants. Only few study subjects were physically active and majority of them felt that their routine work provided them with light physical activity. Around one third of the participants consumed tobacco and alcohol. Around 1/4th of the study participants who were not known hypertensive, were found with increased levels of blood pressure.

Intestinal parasitic infections among expatriate workers in various occupations in Sharjah, United Arab Emirates.

ABSTRACTIntestinal parasitic infections are prevalent throughout many countries. This study aimed to determine the prevalence of intestinal parasite carriers among 21,347 expatriate workers, including food handlers and housemaids attending the public health center laboratory in Sharjah, UAE. Stool sample collection was performed throughout the period between January and December 2013. All samples were examined microscopically. Demographic data were also obtained and analyzed. Intestinal parasites were found in 3.3% (708/21,347) of the studied samples (single and multiple infections). Among positive samples, six hundred and eighty-three samples (96.5%) were positive for a single parasite: Giardia lamblia (257; 36.3%) and Entamoeba histolytica/Entamoeba dispar (220; 31.1%), respectively, whereas mono-infections with helminths accounted for 206 (29.1%) of the samples. Infection rates with single worms were: Ascaris lumbricoides (84; 11.9%), Hookworm (34; 4.8%), Trichuris trichiura (33; 4.7%), Taenia spp. (27; 3.81%), Strongyloides stercoralis (13; 1.8%), Hymenolepis nana (13; 1.8%), and Enterobius vermicularis (2; 0.28%), respectively. Infections were significantly associated with gender (x 2 = 14.18; p = 0.002) with males as the most commonly infected with both groups of intestinal parasites (protozoa and helminths). A strong statistical association was noted correlating the parasite occurrence with certain nationalities (x 2= 49.5, p <0.001). Furthermore, the study has also found a strong statistical correlation between parasite occurrence and occupation (x 2= 15.60; p = 0.029). Multiple infections were not common (3.5% of the positive samples), although one individual (0.14%) had four helminth species, concurrently. These findings emphasized that food handlers with different pathogenic parasitic organisms may pose a significant health risk to the public.

Physical activity participation and the association with work-related upper quadrant disorders (WRUQDs): A systematic review.

Workers in various occupations often report work-related upper quadrant disorders (WRUQDs). Research has shown that associative factors for WRUQDs include psychosocial and environmental elements, gender and physical activity levels. To date, no review has investigated whether physical activity participation is associated with and/or predicts the development of WRUQDs, so the present study set out to determine this. A systematic review was conducted including searches of PubMed (MEDLINE), EMBASE and CINAHL from inception to 31 March 2017. Quantitative studies, including any outcome measure of physical activity participation and its association with and/or prediction of WRUQDs, were included. One reviewer conducted the search and two reviewers independently assessed eligibility and completed methodological quality assessment using a modified Downs and Black checklist. Data were analysed narratively. Eight studies were eligible for inclusion in the final review. The quality of these ranged from moderate to high quality. Three studies reported no statistical difference between physical activity participation and the risk of developing WRUQD. Three studies reported a negative and one study a positive association between physical activity participation and WRUQDs. One study reported that little or no physical exercise participation was a risk factor for WRUQD. There is limited evidence for a negative association between physical activity participation and the development of WRUQDs. However, this was not a consistent finding across all studies included. Further research is indicated in standardizing diagnostic criteria and the measurement of physical activity participation in this patient population.

Praca emocjonalna a wypalenie zawodowe – analiza porównawcza pracy nauczycieli i pracowników sektora usług komercyjnych

Nowadays more and more employees are required to perform emotional labor (EL) which means that they need to express emotions set by the organizational procedures, simultaneously masking the true feelings. Employees, while performing emotional labor, choose between one of the two strategies (surface acting or deep acting) and this leads to e.g., burnout. As the performance of emotional labor and its consequences depend on the specification of work and chosen strategy, it was assumed that the consequences of EL may be different for workers in various occupations. The authors performed a comparative analysis between teachers (N = 129) and professionals of commercial service sector (N = 136). In the analysis the Polish adaptation of deep acting and surface acting scale (DASAS) and the Polish version of OLBI (Oldenburg Burnout Inventory) were used. The statistical verification of hypotheses showed that employees of commercial service sector show a greater tendency toward choosing surface acting than teachers. Furthermore, in the group of teachers negative consequences are more related to emotional exhaustion, while both components of burnout are at the same level among employees of the other group. In both groups of respondents surface acting leads to the increase in burnout. Emotional labor can lead to a variety of negative consequences, e.g., burnout or psychosomatic diseases. Based on this knowledge, organizations can develop standards for the expression of emotions and preventive actions, such as identification with organization, which can counteract the negative EL consequences.

THE PREVALENCE OF CARPAL TUNNEL SYNDROME AMONG FEMALE DAIRY MILKERS

Introduction: Occupation-related Carpal tunnel syndrome represents one of the major health problems among workers in various occupations throughout the world that possess a complex symptoms resulting from compressing the median nerve at the carpal tunnel. Farmers in Egypt are known to use the traditional manual milking of their cattle which needs bilateral repetitive hand movements. Aim of the work: To determine the prevalence and severity of CTS among farmers who performed hand-milking task of cattle and correlate these findings with working years and work duration per hours. Materials and methods: A structured questionnaire was used to determine demographics; work history, present medications and history of any chronic illness. Clinical examination for CTS symptoms as nocturnal exacerbation, Phalen sign, Tinel sign, sensory hyperalgesia, thenar atrophy and thenar weakness. Electrophysiologic studies were done for 240 female farmers, where half of them were milking their cattle manually the other half is used as control. Both groups are matched for age, and Body Mass Index (BMI). Results: The prevalence and clinical severity of CTS were significantly higher among female farmers who milk their cattle than non milkers in both hands (P<0.001), The median nerve motor and sensory conductive study was significantly higher among milkers than non milkers farmers (P value<0.001). The electrophysiological findings were significantly correlated with the longer years of work and longer working hours. Conclusion: These findings suggest that CTS is a significant occupational health issue for farmers that continue the traditional methods of manual milking. Introduction of automated milking machines may help to reduce this problem among the coming generations of the Egyptian farmers who represents a noticeable part of our community

Ergonomic analysis of construction worker's body postures using wearable mobile sensors

Construction jobs are more labor-intensive compared to other industries. As such, construction workers are often required to exceed their natural physical capability to cope with the increasing complexity and challenges in this industry. Over long periods of time, this sustained physical labor causes bodily injuries to the workers which in turn, conveys huge losses to the industry in terms of money, time, and productivity. Various safety and health organizations have established rules and regulations that limit the amount and intensity of workers' physical movements to mitigate work-related bodily injuries. A precursor to enforcing and implementing such regulations and improving the ergonomics conditions on the jobsite is to identify physical risks associated with a particular task. Manually assessing a field activity to identify the ergonomic risks is not trivial and often requires extra effort which may render it to be challenging if not impossible. In this paper, a low-cost ubiquitous approach is presented and validated which deploys built-in smartphone sensors to unobtrusively monitor workers’ bodily postures and autonomously identify potential work-related ergonomic risks. Results indicates that measurements of trunk and shoulder flexions of a worker by smartphone sensory data are very close to corresponding measurements by observation. The proposed method is applicable for workers in various occupations who are exposed to WMSDs due to awkward postures. Examples include, but are not limited to industry laborers, carpenters, welders, farmers, health assistants, teachers, and office workers.

Impact of work-related musculoskeletal disorders on work ability among workers

To assess the impact of work-related musculoskeletal disorders (WRMDs) on work ability among workers. A total of 1686 workers in various occupations, such as administration and education, were enrolled as subjects using the random cluster sampling method. The WRMDs and work ability of all subjects were evaluated using standardized Nordic questionnaires for the analysis of musculoskeletal symptoms and the Work Ability Index (WAI) scale, respectively. Comparison of work ability and its classification between the disease group and the non-disease group was performed by paired t test, RxC table χ2 test, and the Wilcoxon rank-sum test. The relationship between work duration and work ability was analyzed by the Spearman correlation test and a multi-level model. (1). The work ability of workers in the disease group was significantly lower than that in the non-disease group (P<0.0 1). (2) There were significant differences in work ability between workers with different work durations (<10 years, 10-20 years, and ≥20 years) (F=22.124, P< 0.01). With the increase in work duration, the work ability of workers declined in both groups, and the work ability of workers in the disease group (Spearman coefficient rs=-0. 172, P<0.01) had a more significant decline than that in the non-disease group (Spearman coefficient rs=-0.104, P<0.01). WRMDs were important risk factors for the decrease in work ability among workers. (3) There were significant differences in constituent ratios and levels of work ability classification between the disease group and the non-disease group (χ2=121.097, P<0.01; Z=-10.699, P<0.01). The proportions of workers with poor and medium work ability in the disease group were significantly higher than those in the non-disease group, while the proportion of works with excellent work ability in the disease group was significantly lower than that in the non-disease group. The similar characteristics in constituent ratios and levels of work ability classification could be found between the disease group and the non- disease group in various occupations (P<0.01). WRMDs have a harmful effect on the work ability of workers, and the work ability of workers substantially declines with the increase in exposure time (work duration).

Analysis of Occupational Hazards and Safety of Workers in Selected Working Environments within Enugu Metropolis

Workers in various occupations have been subjected to various enormous pains and sufferings. The workplace is supposed to be the second home of the workers, having put in a lot of hours in the workplace each week. Unfortunately, some of the hazards faced by workers are brought about by the ignorance of the workers, resulting in the workers not adhering to the guiding rules in the occupation. Besides, the employers themselves also contribute towards bring these hazards into place in the working environment. This paper, therefore examined the various hazards faced by workers in various occupations in Enugu Metropolis. Occupations in seven industries of agriculture, building, construction, Energy/ power, communications, Education and transport were studied. Questionnaires were used primarily to collect data. Descriptive statistics of frequency distribution and percentage were used in the analysis of data. The findings included that there was no policy guideline in each of the industries studied in the area. It was recommended among other things that employers should improve working conditions of workers in the industries and organize seminars, education programmes and ergonomic interventions so as to ensure that workers remain healthy.

Could CKD Among Young Male Workers be Driven by Dehydration?

Background: Acute kidney injury (AKI) has been recently identified as a strong driver for future development of chronic kidney disease (CKD). Heat stress and repeated dehydration, associated with strenuous labor in agricultural lowlands has been pointed out as a strong risk factor for repeated AKI which in turn could be responsible for the high prevalence of CKD among agricultural workers both in Nicaragua and El Salvador. Methods: Several cross-sectional studies of kidney function (i.e. estimated glomerular filtration rate, eGFR) among workers in various occupations (including agriculture, fishing, mining, coffee, and services), were carried out in low and high altitudes of Nicaragua and El Salvador. In Nicaragua, specific occupational groups were studied examining dehydration in one day of work. Results: In Nicaragua, the prevalence of reduced eGFR was considerably higher in lowland communities for younger age groups of male individuals (between 30 and 40 years of age) without other identified risk factors. Reduced eGFR was higher among mining (47%) and agricultural (in particular sugarcane) (43%) workers, as compared to a lowland service community and high altitude agricultural communities. In El Salvador it was 18% among men compared to 1% prevalence in the high-altitude communities. Some specific occupations such as sugarcane work and salt mining have shown a considerable increase of serum creatinine level after one day exposure to heat combined with heavy workload. Conclusions: These results indicate the need to increase the investigation of occupations with heavy workload and exposure to high temperature in relation to the CKD epidemic in Central America. This could allow for better understanding of what labor practices may be addressed in order to protect populations exposed to work related heat stress.

Work Ability Index (WAI) and Its Association with Psychosocial Factors in One of the Petrochemical Industries in Iran

In recent decades, work ability index (WAI) has been a common practical tool to measure individuals' work ability in many European, Asian and South American countries. However, there is no study concerning work ability in Iran. The aim of this study was to determine the work ability index in an Iranian petrochemical job setting and to examine its relationship with psychosocial factors. A cross-sectional study was conducted among 420 male workers in various occupations. Work ability was evaluated using the WAI questionnaire developed by FIOH; the Job content questionnaire (JCQ) was used to assess psychosocial factors. The mean WAI score was 39.1 (SD=5.7) among workers in the studied petrochemical industry. Multiple linear regression analysis revealed a significant association between mean WAI score and age, job tenure, educational level, rest and sleep status and vocational education. Moreover, the results showed that skill discretion, coworker support and supervisor support were positively associated with the mean WAI score. On the other hand, it was inversely associated with job demands, job strain and job insecurity. This study was the first research to determine WAI in an important industry in Iran. Overall, work ability was in the "Good" category among the workers in the studied field. On the basis of the WAI guidelines, this level should be maintained and promoted to excellent level by providing supportive countermeasures. The WAI score was significantly associated with psychosocial factors. The results showed that even in heavy physical work, factors such as job insecurity, skill discretion, job strain and social support play an important role in maintaining work ability. A positive combination of "psychosocial characteristics" of the job with "individual resources" can promote work ability in such occupations.

Comparing Disparities in the Health-promoting Lifestyles of Taiwanese Workers in Various Occupations

In Taiwan, workplace health promotion programs have been designed on an organizational basis, and the specific health needs for workers within different occupational categories have not usually been taken into account. This study describes the various levels of overall health promoting lifestyles and health-promoting behaviors of workers within different occupational categories,and examines the effects of occupational category, perceived busyness, and BMI level on overall health-promoting lifestyles and health-promoting behaviors. A cross-sectional survey with convenient sampling, comprising a self-reporting questionnaire (which included the Chinese version of the Health-Promoting Lifestyle Profile), was used to measure the overall HPLP and six health-promoting behaviors (nutrition, health responsibility, self-actualization, interpersonal support,exercise, and stress management). A total of 796 participants were recruited. Multiple regression analysis showed that the various occupational categories sustained significant differences in overall HPLP, nutrition, self-actualization, interpersonal support, and stress management(after controlling for some specific factors). Perceived busyness showed positive effects on the overall HPLP, self-actualization, interpersonal support, and stress management. The obese group had less participation in overall health-promoting lifestyles and stress management when compared with the moderate BMI group. Workplace health promotion practitioners should therefore develop specific strategies to target the laborers and workers who demonstrate obesity.

Urinary 1-hydroxypyrene (1-HP) in environmental and occupational studies—A review

A total of 132 studies were identified, of which 25 studies addressed environmental exposure to polycyclic aromatic hydrocarbons (PAHs) in the general population. Of these 9 studies included children. Of 101 studies among workers in various occupations, 32 studies were in petrochemical industries, 29 studies in foundries, 14 studies in asphalt work, 21 studies working in urban air, 6 studies in combustion, 3 studies in soil remediation, and 2 studies in printing. Environmental and occupational studies were identified through an extensive search of the PubMed database up to November 2006. The aim of this review was to provide an overview of studies using urinary 1-hydroxypyrene (1-HP) as a biomarker of environmental and occupational exposure to PAHs. Hereby, we aim to support the current validation of 1-HP by summarizing the evidence of specific PAH exposure and1-HP associations in humans. Urine from more than 7000 children from 8 countries and 3400 adults from 9 countries were included in the 25 studies assessing environmental exposure to PAH. Among the occupational studies 7500 men and women gave urine samples to assess occupational PAH exposure. When measuring biomarkers in urine, volume (and time) or concentrations of creatinine are often used to standardize for diuresis. To be able to compare the included studies we recalculated the given concentrations to mumol 1-HP/mol creatinine. In conclusion, the highest concentrations of urinary 1-HP are found among workers in petrochemical industries among coke-oven workers. Occupational PAH exposure was the major factor determining high urinary concentration of 1-HP. The highest concentrations were observed among workers in the petrochemical industry at work places in Taiwan and China. To evaluate environmental and low-level occupational exposure to PAH it is crucial to provide knowledge on intra- and inter-individual variation in the evaluation of 1-HP. The highest contribution originates from environmental tobacco smoke, but also different country, cooking culture, and behavior influences urinary of 1-HP.

Dutch Musculoskeletal Questionnaire: description and basic qualities

A questionnaire (‘Dutch Musculoskeletal Questionnaire’, DMQ) for the analysis of musculoskeletal workload and associated potential hazardous working conditions as well as musculoskeletal symptoms in worker populations is described and its qualities are explored using a database of 1575 workers in various occupations who completed the questionnaire. The 63 questions on musculoskeletal workload and associated potentially hazardous working conditions can be categorized into seven indices (force, dynamic and static load, repetitive load, climatic factors, vibration and ergonomic environmental factors). Together with four separate questions on standing, sitting, walking and uncomfortable postures, the indices constitute a brief overview of the main findings on musculoskeletal workload and associated potentially hazardous working conditions. Homogeneity of the indices is satisfactory. The divergent validity of the indices is fair when compared with an index of psychosocial working conditions and discomfort during exposure to physical loads. Worker groups with contrasting musculoskeletal loads can be differentiated on the basis of the indices and other factors. With respect to the concurrent validity, it appears that most indices and factors show significant associations with low back and/or neck shoulder symptoms. This questionnaire can be used as a simple and quick inventory for occupational health services to identify worker groups in which a more thorough ergonomic analysis is indicated.
