The purpose of a cross-sectional study was to investigate factors influencing the quality of life among Thai workers in textile dyeing factories. Samples included 205 Thai workers from five textile dyeing factories located in the suburban area of Bangkok in Thailand. Data were collected with a self-administered questionnaire. Scales of the questionnaire had reliability coefficients ranging from 0.70–0.91. The results revealed that the overall quality of life among workers was most likely between good and moderate levels, and the percentage-mean score was 74.77. The seven factors associated with the overall quality of life were co-worker relationships, safety at work in the dimension of accident prevention, job characteristics, supervisory relationships, welfares, marital status, and physical environment. Furthermore, co-worker relationships, accident prevention, and marital status were three considerable predictors accounted for 23% of the variance in the overall quality of life among workers in textile dyeing factories.

Poverty reduction interventions through cash transfers and microcredit have had mixed effects on mental health. In this quasi-experimental study, we evaluate the effect of a living wage intervention on depressive symptoms of apparel factory workers in the Dominican Republic. Two apparel factories in the Dominican Republic. The final sample consisted of 204 hourly wage workers from the intervention (99) and comparison (105) factories. In 2010, an apparel factory began a living wage intervention including a 350% wage increase and significant workplace improvements. The wage increase was plausibly exogenous because workers were not aware of the living wage when applying for jobs and expected to be paid the usual minimum wage. These individuals were compared with workers at a similar local factory paying minimum wage, 15-16 months postintervention. Workers' depressive symptoms were assessed using the Center for Epidemiologic Studies-Depression Scale (CES-D). Ordinary least squares and Poisson regressions were used to evaluate treatment effect of the intervention, adjusted for covariates. Intervention factory workers had fewer depressive symptoms than comparison factory workers (unadjusted mean CES-D scores: 10.6 ± 9.3 vs 14.7 ± 11.6, p = 0.007). These results were sustained when controlling for covariates (β = -5.4, 95% CI -8.5 to -2.3, p = 0.001). In adjusted analyses using the standard CES-D clinical cut-off of 16, workers at the intervention factory had a 47% reduced risk of clinically significant levels of depressive symptoms compared with workers at the comparison factory (23% vs 40%). Policymakers have long grappled with how best to improve mental health among populations in low-income and middle-income countries. We find that providing a living wage and workplace improvements to improve income and well-being in a disadvantaged population is associated with reduced depressive symptoms.

The aim of this work was to determine the reactivity of furniture factory workers to microbial allergens associated with wood dust. Allergological examinations by skin and precipitin tests were performed in 48 workers employed in a factory producing furniture from fibreboards and chipboards, and in 32 healthy urban dwellers not exposed to organic dusts (referents). The skin test was performed by the intradermal method with the saline extracts of the cultures of 3 microbial species (Rahnella sp., Arthrobacter globiformis, Aspergillus fumigatus) associated with wood dust. Skin reactions were recorded after 20 minutes, 8 hours and 24 hours and graded 1-4, depending on the diameter of the reaction. The agar-gel test for the presence of precipitins in serum was performed with the extracts of 15 microbial isolates. The furniture factory workers showed a high skin response to the extracts of environmental microbes. The frequency of early grade 2 reactions (diameter 10 mm) to the extract of Rahnella sp. was 64.6% among furniture workers, being significantly higher (p < 0.001) compared to reference group (18.7%). High frequencies of grade 2 reactions in furniture workers were also found with the extracts of A. globiformis and A. fumigatus (52.1% and 62.5%, respectively). The frequencies of grade 2 delayed (after 8 h) and late (after 24 h) reactions to Rahnella sp. in furniture workers were non-specifically high (97.9%/93.7%) while the response rates to A. globiformis and A. fumigatus were much lower (10.4%/25.0%, and 4.2%/37.5%, respectively). In agar-gel test for detection of precipitins, in most cases very low percentages of positive reactions (0-2.1%) were noted in furniture factory workers. The only exception was a high percentage of positive reactions (27.1%) to the antigen of Pseudomonas maltophilia, which was significantly greater in furniture workers compared to the reference group (p < 0.01). The obtained results suggest that early allergic reactions to microorganisms associated with wood dust are common among workers of furniture industry, which may increase a potential risk of work-related disease in this occupational group.

The present study aimed to find out the utilization prevalence of dental care services among factory workers over a period of one year and factors associated with utilization of dental care services. This was a cross-sectional analytic study. The study population was factory workers in Nava Nakorn Industrial Estate randomly sampled using Probability Proportion to Size Cluster Sampling Method. The tool was a questionnaire about utilization of dental care services. Among the sample group of 1,500 workers from 16 factories, almost 2/3 (63.9%) had never used any dental care services in the previous year while only 36.1% did. A multivariable logistic regression analysis showed that workplace, accommodation, tooth decay, toothache history, transportation, experience in using social security fund for dental care services, availability and accessibility of dental care services, brushing teeth regularly after meals, using dental care services regularly in a dental clinic, and agreement with the idea that a tooth extraction and medication by a dentist could reduce the risk of progression of disease, statistical significance (p-value < 0.05), were factors associated with the utilization of dental care services at R2 (The Nagelkerke R Square) 0.38. That the prevalence of the factory workers who did not use dental care services during the last one year was 63.9 percent. This study identified three groups of factors associated with the utilization of dental care services as: 1) Predisposing factors, 2) Enabling factors, and 3) Need factors.

Hazardous factories: Nigerian evidence.

The past 15 years have seen an increasing governmental and corporate concern for the environment worldwide. For governments, information about the environmental performance of the industrial sector is required to inform macro-level decisions about environmental targets such as those required to meet UN directives. However, in many African, Asian, and Latin American countries, researching and reporting company environmental performance is limited. This article serves as a contribution to filling the gap by presenting evidence of physical and chemical risk in Nigerian factories. One hundred and three factories with a total of 5,021 workers were studied. One hundred and twenty physical and chemical hazards were identified and the result shows a high number of workers exposed to such hazards. The study also reveals that workers' awareness level of chemical hazards was high. Yet the danger was perceived in behavioral terms, especially by manufacturing firms, which tend to see environmental investment in an increasingly global economy as detrimental to profitability.

Indian tea industry workers are exposed to various exposures at their workplace. To investigate the respiratory health of Indian tea industry workers. We administered a respiratory questionnaire to and measured lung function in workers of 34 tea gardens and 46 tea factories. We used correlation matrices to test the association between their respiratory symptoms and lung functions. The garden workers complained of shortness of breath 3 times higher than the factory workers. However, nasal allergy was more predominant among the factory workers compared to garden workers (69.6% vs 41.2%, p=0.02). The factory workers had higher total (median 107.3% vs 92.9%, p=0.05, as measured by R at 5 Hz) and peripheral airway resistance (143.8% vs 61.1%, p=0.005, as measured by R at 5-20 Hz) than the garden workers. Respiratory symptoms were inversely associated with airway obstruction as measured by the ratio between forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) and positively correlated with increased overall airway reactance among the workers. Respiratory symptoms and increased allergen susceptibility of Indian tea industry workers due to occupational exposures warrant routine systematic surveillance of their workplace air quality and health monitoring.

Background Chronic respiratory symptoms including chronic cough, chronic phlegm, wheezing, shortness of breath, and chest pain are manifestations of respiratory problems which are mainly evolved as a result of occupational exposures. This study aims to assess determinants of chronic respiratory symptoms among pharmaceutical factory workers. Methods A case control study was carried out among 453 pharmaceutical factory workers with 151 cases and 302 controls. Data was collected using pretested and structured questionnaire. The data was analyzed using descriptive statistics and bivariate and multivariate analysis. Result Previous history of chronic respiratory diseases (AOR = 3.36, 95% CI = 1.85–6.12), family history of chronic respiratory diseases (AOR = 2.55, 95% CI = 1.51–4.32), previous dusty working environment (AOR = 2.26, 95% CI = 1.07–4.78), ever smoking (AOR = 3.66, 95% CI = 1.05–12.72), and service years (AOR = 1.86, 95% CI = 1.16–2.99) showed statistically significant association with chronic respiratory symptoms. Conclusion Previous history of respiratory diseases, family history of chronic respiratory diseases, previous dusty working environment, smoking, and service years were determinants of chronic respiratory symptoms. Public health endeavors to prevent the burden of chronic respiratory symptoms among pharmaceutical factory workers should target the reduction of adverse workplace exposures and discouragement of smoking.

OBJECTIVES: To evaluate the risk of cancer and other diseases among workers engaged in aircraft manufacturing and potentially exposed to compounds containing chromate, trichloroethylene (TCE), perchloroethylene (PCE), and mixed solvents. METHODS: A retrospective cohort mortality study was conducted of workers employed for at least 1 year at a large aircraft manufacturing facility in California on or after 1 January 1960. The mortality experience of these workers was determined by examination of national, state, and company records to the end of 1996. Standardised mortality ratios (SMRs) were evaluated comparing the observed numbers of deaths among workers with those expected in the general population adjusting for age, sex, race, and calendar year. The SMRs for 40 cause of death categories were computed for the total cohort and for subgroups defined by sex, race, position in the factory, work duration, year of first employment, latency, and broad occupational groups. Factory job titles were classified as to likely use of chemicals, and internal Poisson regression analyses were used to compute mortality risk ratios for categories of years of exposure to chromate, TCE, PCE, and mixed solvents, with unexposed factory workers serving as referents. RESULTS: The study cohort comprised 77,965 workers who accrued nearly 1.9 million person-years of follow up (mean 24.2 years). Mortality follow up, estimated as 99% complete, showed that 20,236 workers had died by 31 December 1996, with cause of death obtained for 98%. Workers experienced low overall mortality (all causes of death SMR 0.83) and low cancer mortality (SMR 0.90). No significant increases in risk were found for any of the 40 specific cause of death categories, whereas for several causes the numbers of deaths were significantly below expectation. Analyses by occupational group and specific job titles showed no remarkable mortality patterns. Factory workers estimated to have been routinely exposed to chromate were not at increased risk of total cancer (SMR 0.93) or of lung cancer (SMR 1.02). Workers routinely exposed to TCE, PCE, or a mixture of solvents also were not at increased risk of total cancer (SMRs 0.86, 1.07, and 0.89, respectively), and the numbers of deaths for specific cancer sites were close to expected values. Slight to moderately increased rates of non-Hodgkin's lymphoma were found among workers exposed to TCE or PCE, but none was significant. A significant increase in testicular cancer was found among those with exposure to mixed solvents, but the excess was based on only six deaths and could not be linked to any particular solvent or job activity. Internal cohort analyses showed no significant trends of increased risk for any cancer with increasing years of exposure to chromate or solvents. CONCLUSIONS: The results from this large scale cohort study of workers followed up for over 3 decades provide no clear evidence that occupational exposures at the aircraft manufacturing factory resulted in increases in the risk of death from cancer or other diseases. Our findings support previous studies of aircraft workers in which cancer risks were generally at or below expected levels.   PMID:10615290

Coffee processing causes organic dust exposure which may lead to development of respiratory symptoms. Previous studies have mainly focused on workers involved in roasting coffee in importing countries. This study was carried out to determine total dust exposure and respiratory health of workers in Tanzanian primary coffee-processing factories. A cross sectional study was conducted among 79 workers in two coffee factories, and among 73 control workers in a beverage factory. Personal samples of total dust (n = 45 from the coffee factories and n = 19 from the control factory) were collected throughout the working shift from the breathing zone of the workers. A questionnaire with modified questions from the American Thoracic Society questionnaire was used to assess chronic respiratory symptoms. Differences between groups were tested by using independent t-tests and Chi square tests. Poisson Regression Model was used to estimate prevalence ratio, adjusting for age, smoking, presence of previous lung diseases and years worked in dusty factories. All participants were male. The coffee workers had a mean age of 40 years and were older than the controls (31 years). Personal total dust exposure in the coffee factories were significantly higher than in the control factory (geometric mean (GM) 1.23 mg/m3, geometric standard deviation (GSD) (0.8) vs. 0.21(2.4) mg/m3). Coffee workers had significantly higher prevalence than controls for cough with sputum (23% vs. 10%; Prevalence ratio (PR); 2.5, 95% CI 1.0-5.9) and chest tightness (27% vs. 13%; PR; 2.4, 95% CI 1.1-5.2). The prevalence of morning cough, cough with and without sputum for 4 days or more in a week was also higher among coffee workers than among controls. However, these differences were not statistically significant. Workers exposed to coffee dust reported more respiratory symptoms than did the controls. This might relate to their exposure to coffee dust. Interventions for reduction of dust levels and provision of respiratory protective equipment are recommended.

This research reports on a pilot industrial hygiene study that was performed at four footwear factories and two equipment factories in Thailand. Workers in these factories were exposed through inhalation and dermal contact to a large number of organic vapors from solvents and cements that were hand applied. In addition, these workers were exposed to highly toxic isocyanates primarily through the dermal route. A total of 286 personal air samples were obtained at the four footwear factories using organic vapor monitors; individual job tasks were monitored using a real-time MIRAN Spectrometer. A total of 64 surface, tool, or hand samples were monitored for isocyanates using surface contamination detectors. Real-time measurements were also obtained for organic vapors in two equipment factories. From 8% to 21% of the workers sampled in each footwear factory were overexposed to mixtures of chemicals from solvents and cements. Up to 100% of the workers performing specific job tasks were overexposed to mixtures of chemicals. From 39% to 69% of the surface samples were positive for unreacted isocyanates. Many of the real-time measurements obtained in the equipment factories exceeded occupational exposure limits. Personal protective equipment and engineering controls were inadequate in all of the factories.

Abstract The socialist factory, as the ‘incubator’ of the new socialist (wo)man, is a productive entry point for the study of socialist modernization and its contradictions. By outlining some theoretical and methodological insights gathered through field-research in factories in former Yugoslavia, we seek to connect the state of labour history in the Balkans to recent breakthroughs made by labour historians of other socialist countries. The first part of this article sketches some of the specificities of the Yugoslav self-managed factory and its heterogeneous workforce. It presents the ambiguous relationship between workers and the factory and demonstrates the variety of life trajectories for workers in Yugoslav state-socialism (from model communists to alienated workers). The second part engages with the available sources for conducting research inside and outside the factory advocating an approach which combines factory and local archives, print media and oral history.

Shoe manufacturing workers are exposed daily to an extensive range of potential physical and chemical occupational hazards. Shoe manufacturing in Indonesia is one of the industrial sectors that has shown sustained growth amongst the newly industrialized countries (NICs). In this study, we investigated the possible potential exposure of the workers to physical and occupational hazards and determined the prevalence of occupational skin diseases at a shoe manufacturing factory in Indonesia. A cross-sectional study on the observation of the working process and an inventory and risk assessment of exposure to the chemicals used. Classification of chemicals as potential sensitizers/irritants and qualitative assessments of these chemicals were done. Workers were examined and interviewed using the Nordic Occupational Skin Questionnaire-2002/LONG. The risk of Occupational skin diseases (OSD) at the shoe factory was mainly related to the exposure of the workers' skin to potential physical and chemical hazards in hot and humid environmental conditions. From a total of 514 workers, 8.5 % reported current OSD and 4.8 % reported a history of OSD. Occupational skin diseases were diagnosed in 29 % of the workers by dermatologists and 7.6 % had an occupational contact dermatitis (OCD). Of the 39 workers with contact dermatitis, 33 consented to being patch tested, 14 (3 %) workers showed a positive results and considered as having an occupational allergic contact dermatitis (OACD) and 25 (4.9 %) had an occupational irritant contact dermatitis (OICD). We observed a repeated and prolonged exposure of the workers to numerous physical and chemical skin hazards at this factory.

The effects of outsourcing on occupational health and safety: a comparative study of factory-based workers and outworkers in the Australian clothing industry.

Outsourcing has become increasingly widespread throughout industrialized societies over the past 20 years. Accompanying this has been a renewed growth in home-based work, sometimes using new technologies (telework) but also entailing a re-emergence of old forms, such as clothing outwork, used extensively 100 years ago. A growing body of research indicates that changes to work organization associated with outsourcing adversely affect occupational health and safety (OHS), both for outsourced workers and for those working alongside them. This study assessed the OHS implications of the shift to home-based workers in the Australian clothing industry by systematically comparing the OHS experiences of 100 factory-based workers and 100 outworkers. The level of self-reported injury was over three times higher among outworkers than factory-based workers undertaking similar tasks. The most significant factor explaining this difference was the payment system. All outworkers were paid solely by the piece, whereas factory workers were paid either under a time plus production bonus system or solely on a time basis. While the incidence of injury was far higher among outworkers, factory-based workers paid under an incentive system reported more injuries than those paid solely on a time basis. Increasing injury was correlated with piecework payment systems.

To identify the occupational hazard factors in an accumulator factory, to analyze the status of internal and external lead exposure and evaluate the impact of lead exposure on the health of workers in the accumulator industry, and to provide a theoretical basis for improved lead exposure criteria and technical support for the control of lead contamination in the accumulator industry. An on-site investigation was carried out to monitor and evaluate the lead fume and dust in the workplaces of an accumulator factory, and occupational health examination was performed in all workers. The occupational hazard safeguards in the accumulator factory were unadvanced. The contamination of lead fume and dust was serious. The abnormal rate of blood lead was up to 79.80%, and many workers developed anemia and mild peripheral nerve disease. Lead contamination is serious in the accumulator factory, leading to poor health of workers. It is essential to take effective control measures, improve the working environment, provide occupational health education, increase workers' self-protection awareness, and periodically conduct occupational hazard monitoring and health surveillance. The government must reinforce occupational health supervision of such enterprises.

Concerns about the nutritional status of Cambodian garment workers were raised years ago but data are still scarce. The objectives of this study are to examine the nutritional, hemoglobin and micronutrient status of female workers in a garment factory in Phnom Penh, Cambodia, and to assess if body mass index is associated with hemoglobin and/or micronutrient status. A cross-sectional survey was conducted among 223 female workers (nulliparous, non-pregnant) at a garment factory in Phnom Penh. Anthropometric measurements were performed and blood samples were taken to obtain results on hemoglobin, iron, vitamin A, vitamin B12 and inflammation status (hemoglobinopathies not determined). Bivariate correlations were used to assess associations. Overall, 31.4% of workers were underweight, 26.9% showed anemia, 22.1% showed iron deficiency, while 46.5% had marginal iron stores. No evidence of vitamin A or vitamin B12 deficiency was found. Body mass index was associated with serum ferritin (negative) and serum retinol-binding protein (positive) concentrations, but not strongly. A comparison between underweight and not underweight workers resulted in distinctions for iron deficiency and iron deficiency anemia, with a higher prevalence among not underweight. The prevalence of underweight, anemia and poor iron status was high. Young and nulliparous female garment workers in Cambodia might constitute a group with elevated risk for nutritional deficiencies. Strategies need to be developed for improving their nutritional, micronutrient and health status. The poor iron status seems to contribute to the overall prevalence of anemia. Low hemoglobin and iron deficiency affected both underweight and those not underweight. Despite the fact that body mass index was negatively associated with iron stores, true differences in iron status between underweight and not underweight participants cannot be confirmed.

A comparison between underweight and not underweight workers resulted in distinctions for iron deficiency and iron deficiency anemia, with a higher prevalence among not underweight. Conclusions: The prevalence of underweight, anemia and poor iron status was high. Young and nulliparous female garment workers in Cambodia might constitute a group with elevated risk for nutritional deficiencies. Strategies need to be developed for improving their nutritional, micronutrient and health status. The poor iron status seems to contribute to the overall prevalence of anemia. Low hemoglobin and iron deficiency affected both underweight and those not underweight. Despite the fact that body mass index was negatively associated with iron stores, true differences in iron status between underweight and not underweight participants cannot be confirmed.

Examination of the records of employees leaving an electronics factory over three-and-a-half years showed that a significantly greater proportion left the shop floor (where soldering took place) because of ill health than left the stores and office areas. This difference was largely due to work-related respiratory disease in those whose job was soldering. Shop floor workers leaving for health reasons also had increased sickness certification due to respiratory illness compared to stores and office workers. These findings suggest that work-related respiratory illness is a significant cause of morbidity and loss of employment in solderers working at the factory and that this has been a longstanding problem with its onset before the first recorded cases of occupational asthma caused by solder flux containing colophony.

The results of a survey on workers potentially exposed to cobalt in the Bergamo Province are reported. Its aim is to assess the number of workers at risk of developing respiratory disease due to the inhalation of metallic cobalt. Interest was shown after an examination of 11 cases of 'hard metal disease', which we diagnosed, in workers who came from different production areas and had different degrees of exposure. A first group of 45 factories with potential cobalt exposure was identified by consulting the archives of the Local Sanitary Units (USSL) and of the Chamber of Commerce, and by use of the telephone directory and requesting information from the producers and users of Widia tools. A second group of 2039 factories was selected from those industrial activities where we had previously ascertained the presence of grinding operations using hard metal tools with diamond wheels. This study is related to all the factories in the first group and 10% of the factories in the second group. More than 304 inspections were carried out. In this context 403 exposed workers were identified. Workplace air measurements (250 samples) and biological monitoring (> 600 samples) to determine the exposure levels to cobalt were performed. The results show an unexpected diffuse occupational exposure in different production areas where the airborne cobalt is frequently underestimated and higher than the TLV.

Castor bean allergy in the upholstery department of a furniture factory.

In this study, undertaken to identify the cause of allergy in several upholstery workers in a furniture factory, the workers were handling several different materials, including glue, silicone spray, upholstery fabrics, and felt. Radio-allergo-sorbent test (RAST) assays showed that sera from sensitised workers contained specific IgE towards the felt; however, further investigations using RAST showed that the allergen was not the felt itself but a contaminant of the felt. The felt was manufactured from sacks, some of which had been used to store castor beans. The sera with raised IgE to the felt also had raised IgE to the castor bean extract. By means of RAST inhibition we confirmed that castor bean allergens in the felt were solely responsible for the raised IgE in the sera. The in-vitro RAST results were found to correlate well with the in-vivo pick tests and clinical symptoms. PMID:7272244

Liquid epoxide resins, solvents and solvent-modified epoxide resins, as well as hardeners for epoxide resins, appear to be skin and mucosa irritants of different intensity and possibly have allergenic properties. Therefore, it is required that the employees are qualified and industrial safety rules are followed when these substances are in use in the manufacturing process. Our study evaluated the state of dentition and analysed the loss of teeth in the workers of the laminate and composite materials department of aircraft factory. The research has been carried out in a group of 114 workers, which consisted of 88 men and 26 women 20 to 61 years old. The control group consisted of 41 workers of the administration department in the aircraft factory who did not have any contact with chemical compounds. The workers in the studied group are characterised as having an unsatisfactory state of dentition, as shown by the high rate of lost teeth (74 %). Statistically significant difference between the studied group and the control was found when the relationship between the number of lost molar teeth in women in the studied group and those in the control group is taken into consideration, a statistically significant difference appears to refer to teeth 46 and 27. The same statistically important correlation between men in the control and studied groups concerns teeth 16. The research data shows that incisor teeth are the least frequently extracted teeth in the whole population studied. Statistically significant differences can be noted for teeth 21 and 23 between the women in the control group and those in the studied one. Future studies are necessary to assess the potential relationship between the loss of teeth among workers of the department of laminate and composite materials of aircraft factory and their workplace.

One of the most common procedures for risk assessment of upper limb work-related musculoskeletal disorders (UL-WMSDs) in Italy is the OCRA synthetic index, which is recommended as the preferred method in the ISO standard 11228-3. The aim of the survey was to assess the risk of UL-WMSDs due to repetitive strain and movements in thirty factories of the sofa industry located in a large geographic area of southern Italy. The most characteristic working tasks of the manufacturing process were studied: filling preparation workers, leather-cutting operators, sewing and upholstery-assembly workers. The single tasks were carried out almost exclusively manually, with features of a handicraft approach. Data were collected through questionnaires and video tape recordings in each factory. The mean value of the OCRA index of every group of factories was calculated by weighting the values of the index of each single task group with the number of the workers. Figures obtained in the different factories showed values of the OCRA index ranging between 4 and 15. A 2,9 OCRA value was attributed to a low exposure group. Even though the work tasks analyzed were characterized by long duration of the manufacturing cycle (between 5 and 60 min), a particular but rigorous application of the OCRA procedures made it possible for a detailed risk assessment to be made for each of the working groups analysed.

Women in Bangladesh experience high rates of Intimate Partner Violence (IPV). IPV is more prevalent against income earning women compared to their non-earning counterparts, and Workplace Violence (WPV) is also common. Such violence is a violation of women's rights, and also constrains them from contributing to their personal growth, household, community and the economy at large. There is limited evidence on what works to prevent IPV and WPV amongst garment workers. This paper describes an evaluation of HERrespect, an intervention which aims to reduce IPV and WPV against female garment workers in and around Dhaka, Bangladesh. The trial employs a quasi-experimental design, with four intervention and four control factories. In the intervention factories a randomly selected cohort of married female line workers, a cohort of male line workers, and all middle management staff received the intervention. The intervention strategies involved (1) gender transformative group-based training for workers and management staff; (2) joint session between workers (15 female and male) and middle-management staff; (3) factory-wide activities; (4) awareness raising among top management; (5) factory policy review and development and 6) a community based campaign. For the evaluation, a cohort of randomly selected female workers and a cohort of selected management staff have been established. All workers (n = 800) and management staff (n = 395) from these cohorts were interviewed at baseline using two different questionnaires, and will be interviewed in the endline, 24 months post-baseline. Intention to treat analysis will be used for assessing the impact of HERrespect, comparing the intervention and control factories. To our knowledge this is the first study that seeks to evaluate the impact on IPV and WPV, of group sessions with female workers, male workers, and management; factory-wide campaigns and a community intervention among female garment workers in Bangladesh. Apart from informing programmers and policy makers about intervention effectiveness in reducing IPV and WPV against female garment workers this study will also present evidence on an intervention tailored to the situation in the garment sector, which makes HERrespect scalable.

Pay Matters: The Piece Rate and Health in the Developing World.

PubMed

Davis, Mary E

Piece rate pay remains a common form of compensation in developing-world industries. While the piece rate may boost productivity, it has been shown to have unintended consequences for occupational safety and health, including increased accident and injury risk. This paper explores the relationship between worker pay and physical and emotional health, and questions the modern day business case for piece rate pay in the developing world. The relationship between piece rate and self-reported measures of physical and emotional health is estimated using a large survey of garment workers in 109 Vietnamese factories between 2010 and 2014. A random effects logit model controls for factory and year, predicting worker health as a function of pay type, demographics, and factory characteristics. Workers paid by the piece report worse physical and emotional health than workers paid by the hour (OR = 1.38-1.81). Wage incentives provide the most consistently significant evidence of all demographic and factory-level variables, including the factory's own performance on occupational safety and health compliance measures. These results highlight the importance of how workers are paid to understanding the variability in worker health outcomes. More research is needed to better understand the business case supporting the continued use of piece rate pay in the developing world. Copyright © 2016 The Author. Published by Elsevier Inc.

The aims of this study were to investigate the relations of occupational exposures in tile industry to lung function and to evaluate potential interaction between smoking and tile dust exposure containing silica. A cross-sectional study of 232 workers (response rate 100%) in a tile factory and 76 office workers (response rate 73%) from four factories in Thailand was conducted in 2006-2007. Participants answered a questionnaire and performed spirometry. Factory workers had lower spirometric functions than office workers, especially those with high dust exposure. There was a dose-response relation between duration of dust exposure and FEV1 and FVC, the adjusted effect of ≥ 21 years of exposure on FEV1 being -240 ml (-100 to -380) and on FVC -300 ml (-140 to -460). The adverse effect of dust on lung function was larger in current smokers suggesting synergism between smoking and tile dust exposure. This study provides evidence that long-term exposure to dust in tile industry is related to lung function reduction. There was a suggestion of synergistic effect between dust exposure and smoking. Tile factories should consider measures to reduce dust exposure and arrange spirometry surveillance for workers with such exposure. Smoking cessation should be promoted to prevent harmful effects of occupational tile dust exposure.

Workers in Mexico's maquiladoras (assembly plants) are mainly young, single women, many of whom could benefit from emergency contraceptive pills (ECPs). Because ECPs are readily available in Mexico, women who know about the therapy can obtain it easily. Do maquiladora workers know about the method? Could worksite programs help increase awareness? To investigate these questions, we conducted a five-month intervention during which workers in three maquiladoras along the Mexico-United States border could attend educational talks on ECPs, receive pamphlets, and obtain kits containing EC supplies. Among the workers exposed to our intervention, knowledge of ECPs increased. Reported ECP use also increased. Although our intervention apparently increased workers' knowledge and use, the factory proved to be a difficult intervention setting. Problems we experienced included a factory closure and management/staff opposition to certain project elements. Future studies should continue to investigate work-site interventions and other strategies to reach workers.

Plastic resins are complex chemicals that contain toluene diisocyanate (TDI) and/or trimellitic anhydride (TMA), which cause occupational allergies (OA), including respiratory allergies. Serum IgGs against TDI and TMA have been suggested as potential markers of the exposure status and as exploring cause of OA. Although TDI-specific IgG has been examined for suspected OA, TMA-specific IgG is not commonly evaluated in a urethane foam factory. This study therefore investigated both TDI- and TMA-specific IgGs in suspected OA patients and to evaluate the usefulness of the measurement of multiple chemical-specific IgG measurement for practical monitoring. Blood samples were collected from two male workers who developed respiratory allergies supposedly caused by occupational exposure to TDI and/or TMA for the presence of TDI- and TMA-specific IgGs. In addition, blood samples from 75 male workers from a urethane foam factory, along with 87 male control subjects, were collected in 2014 and tested for the same IgGs in 2014. The presence and levels of TDI- and TMA-specific serum IgGs were measured using dot blot assays. We found that controls had mean concentrations of TDI- and TMA-specific IgGs of 0.98 and 2.10 μg/mL, respectively. In the two workers with respiratory allergies, the TDI-specific IgG concentrations were 15.6 and 9.51 μg/mL, and TMA-specific IgG concentrations were 4.56 and 14.4 μg/mL, which are clearly higher than those in controls. Mean concentrations of TDI- and TMA-specific IgGs in the factory workers were 1.89 and 2.41 μg/mL, respectively, and are significantly higher than those of the controls (P < 0.001 and P < 0.026 for TDI- and TMA-specific IgGs, respectively). The workers suspected of OA showed an evidently high level of TDI- and TMA-specific IgG, and these levels in workers at the urethane foam factory were also significantly higher than those in controls. In conclusion, the measurement of TDI- and TMA-specific IgG among workers using plastic resins is helpful to monitor their exposure status.

Occupational IgE sensitisation to phytase, a phosphatase derived from Aspergillus niger.

1999-07-01

Phytase is a phosphatase derived from Aspergillus niger that enhances phosphate bioavailability in the gut, and therefore has been increasingly used as an animal feed additive since the early 1990s. The aim of this study was to assess whether work related respiratory symptoms among workers in a so called premix factory producing animal feed additives, could be due to type I (mediated by immunoglobulin E (IgE) allergic sensitisation to phytase. Preparations of specific IgE against phytase as used in the factory were assessed by enzyme immunoassay (EIA) in serum samples of 11 exposed workers who regularly handled the enzyme, in 11 office and laboratory workers of the same plant (non-exposed internal controls), and in 19 laboratory animal workers as external controls. The factory workers also completed a questionnaire on common and work related respiratory symptoms. Depending on the cut off level in the EIA for IgE, and the preparation used as coated allergen, antiphytase sensitisation was found in one to four of the 19 external controls, in one to five of the 11 internal controls, and in four to 10 of the 11 exposed workers. Strongest IgE reactions were found in four exposed workers who reported work related respiratory symptoms, particularly wheezing, and in one internal control who possibly had become sensitised because the structure of the factory building did not preclude airborne exposure in the offices and corridors of the plant. Experiments with inhibition EIA for IgE showed that (a) phytase of another commercial source was only partially cross reactive with phytase as used in the premix factory, and (b) phytase used as an animal feed additive did not cross react with common mould extracts, except for extracts from the species of origin, Aspergillus niger. The amount of IgE binding phytase in Aspergillus niger was estimated to be between 0.1% and 1% of the extractable mould proteins. Phytase is a potentially important new occupational allergen causing specific IgE immune responses among exposed workers. Such IgE sensitisation could probably be the cause of work related asthmatic and other respiratory symptoms if no effective measures are taken to prevent airborne occupational exposure at sites where phytase is handled, particularly during addition of enzyme preparations to animal feed.

Exposure to benzene in air is a concern in Thailand, particularly since it was observed that the incidence of blood-related cancers, such as leukemia and lymphoma, has increased in the past few decades. In Bangkok, the mean atmospheric levels of benzene on main roads and in schools were 33.71 and 8.25 ppb, respectively, while in gasoline service stations and petrochemical factories the mean ambient levels were 64.78 and 66.24 ppb, respectively. Cloth vendors (22.61 ppb) and grilled-meat vendors (28.19 ppb) working on the roadsides were exposed to significantly higher levels of benzene than the control group (12.95 ppb; p<0.05). Bangkok school children (5.50 ppb) were exposed to significantly higher levels of benzene than provincial school children (2.54 ppb; p<0.01). Factory workers (73.55 ppb) and gasoline service attendants (121.67 ppb) were exposed to significantly higher levels of benzene than control workers (4.77 ppb; p<0.001). In accordance with the increased benzene exposures, levels of urinary trans,trans-muconic acid (MA) were significantly increased in all benzene-exposed groups. In school children, the levels of MA were relatively high, taking into account the much lower level of exposure. Blood benzene levels were also significantly increased in Bangkok school children (77.97 ppt; p<0.01), gasoline service attendants (641.84 ppt; p<0.05) and factory workers (572.61 ppt; p<0.001), when compared with the respective controls. DNA damage, determined as DNA strand breaks, was found to be elevated in gasoline service attendants, petrochemical factory workers, and Bangkok school children (p<0.001). The cytogenetic challenge assay, which measures DNA repair capacity, showed varying levels of significant increases in the numbers of dicentrics and deletions in gasoline service attendants, petrochemical factory workers and Bangkok school children, indicating a decrease in DNA repair capacity in these subjects.

Background Vietnam has experienced a strong wave of migrants to urban and industrialized areas. This is a challenge for both local and national governments, which need to address the problems of the poor and socially marginalized, including providing housing for rural-to-urban migrants. Poor housing and the economic burden of house renting are increasingly recognized as determinants of both physical and mental health. Objectives This paper examined the association between renting accommodation and income satisfaction and living conditions of female workers in light manufacturing industries in Vietnam. Methods A cross-sectional study was implemented with quantitative survey of 2,818 female workers in 10 light manufacturing factories in 3 industrial zones by a self-administered questionnaire. Results Over 38% of female workers had to rent accommodation. The average expense for accommodation, water and electricity accounted for 30.1% of renters' income, which is 7.2% (CI 95%, 5.3–9.3%) higher than for non-renters. A higher proportion of renters than non-renters considered their income was unstable and insufficient for living costs. In addition, only 7.2% of renters reported that their living conditions were suitable, notably lower than non-renters (22.4%). Conclusion The study showed the economic burden of renting accommodation on workers' income satisfaction and living conditions. The findings have implications for an adequate housing access strategy for workers including the integration of housing development in the planning and development of industrial zones and factories.

Wolf, D L

The commercialization of agriculture, increasing landlessness, and an expanding labor class in rural areas of Java are all the result of industrialization. This work discusses the effect of female employment on marriage patterns of women working in rural factories. The central point is that employment has not only increased the financial autonomy of these women, but also increased the level of control they have over the choice of marriage partners. The data set used for analysis consisted of the observations of all factory workers and all non-factory females age 15-24 located in an agricultural village. The observations were make over a 15 month period between 1981-83. A follow up visit was made in 1986 and the following conclusions were then made: 1) the village study gave detailed data, but the data set was not large enough, thus a follow up study that encompasses more people is called for; 2) young rural female factory workers are more likely to chose their marriage partners than those engaged in traditional village labor. Of those that married and worked in factories, their fertility rate was significantly lower, compared to non-factory workers. Factory workers also had different family structures, because they spent less time living in extended families because of a larger income for the couple. This study indicates that increased economic control results in increased life decision control. This changed the daughter's economic relationship with her family and gives her more control in marriage decisions.

The aim of this study is to find out the causes of skin diseases in one-third of the staff of a perfume factory, in which 10 different perfume sprays were being manufactured. Site inspection, dermatological examination and patch testing of all 26 persons at risk with 4 perfume oils and 30 ingredients of them. The results showed 6 bottlers were found suffering from allergic contact dermatitis, 2 from irritant contact dermatitis, 12 workers showed different strong reactions to various fragrances. The main causes of allergic contact dermatitis were 2 perfume oils (12 cases) and their ingredients geraniol (12 cases), benzaldehyde(9), cinnamic aldehyde (6), linalool, neroli oil, terpenes of lemon oil and orange oil (4 each). Nobody was tested positive to balsam of Peru. Job changes for office workers, packers or printers to other rooms, where they had no longer contact with fragrances, led to a settling. To conclude, automation and replacement of glass bottles by cartridges from non-fragile materials and using gloves may minimize the risk.

Methyl alcohol poisoning has been mainly reported in community. Two cases of methyl alcohol poisoning occurred in a small-sized subcontracted factory which manufactured smartphone parts in Korea. One young female patient presented with dyspnea and visual disturbance. Another young male patient presented with visual disturbance and myalgia. They treated with sodium bicarbonate infusion and hemodialysis for metabolic acidosis. In addition, he received ethyl alcohol per oral treatment. Her and his urinary methyl alcohol concentration was detected as 7.632 mg/L, 46.8 mg/L, respectively, although they were treated hemodialysis. Results of the working environment measurement showed that the concentration of methyl alcohol (1030.1-2220.5 ppm) in the air exceeded the time weighted average (200 ppm). They were diagnosed with optic neuropathy due to methyl alcohol poisoning and still have visual impairment. Workers who hired as dispatched employees in a small-sized subcontracted factory were exposed to high concentrations of methyl alcohol. The workplace had poor ventilation system. In addition, workers did not wear proper personal protect equipment. Working environment measurement and annual chekups for workers were not performed. They were in a blind spot to occupational safety and health. More attention is needed to protect vulnerable workers' health.

Tobacco use is considered to be global pandemic. The study was done to assess the effectiveness of smoking cessation intervention among workers by motivational interviewing among handicraft factories, Jodhpur, Rajasthan. An interventional study was carried out among 400 handicraft factory workers on the basis of inclusion and exclusion criterion. Twenty one handicraft factories were taken into consideration. Training, Standardization and Calibration of Examiners was carried out in the public health department. The structured pre-tested proforma and Fagerstrom questionnaire was used to record the data. Four sessions of intervention were given to workers. Follow ups were carried out after 1 month, 3month and 6month. Paired t-test was used to compare Fagerstrom/smoking analysis mean scores among study and control groups before and after intervention. showed that in study group, a percentage change of +1.2%, seen in high dependence category and -1.5 in very high dependence and after 6 months the change was+14.2%, 18.7%, -19.2% in Very low dependence, Low dependence, Medium dependence, -11.8% was seen in high dependence category and -1.8 in very high dependence. When comparison was done among Fagerstrom/smoking analysis mean scores among study subjects before and after intervention. It was found that there was a significant difference between the mean scores of Fagerstrom/smoking analysis between baseline - 3 months, 3 months to 6 months and 6 months to 9 months among study group as compared to control group. Tobacco addiction produces neurological and behavioural change, optima; approach involving behavioural change and pharmacotherapy are needed.

Nuclear anomalies in the buccal cells of calcite factory workers

PubMed Central

2010-01-01

The micronucleus (MN) assay on exfoliated buccal cells is a useful and minimally invasive method for monitoring genetic damage in humans. To determine the genotoxic effects of calcite dust that forms during processing, MN assay was carried out in exfoliated buccal cells of 50 (25 smokers and 25 non-smokers) calcite factory workers and 50 (25 smokers and 25 non-smokers) age- and sex-matched control subjects. Frequencies of nuclear abnormalities (NA) other than micronuclei, such as binucleates, karyorrhexis, karyolysis and ‘broken eggs', were also evaluated. Micronuclei and the other aforementioned anomalies were analysed by two way analysis of covariance. The linear correlations between the types of micronucleus and nuclear abnormalities were determined by Spearman's Rho. There was a positive correlation between micronuclei and other types of nuclear abnormalities in accordance with the Spearman's Rho test. Results showed statistically significant difference between calcite fabric workers and control groups. MN and NA frequencies in calcite fabric workers were significantly higher than those in control groups (p < 0.05). The results of this study indicate that calcite fabric workers are under risk of significant cytogenetic damage. PMID:21637497

A survey was made of a random sample of workers from the machine shops, assembly lines, and stock and store departments of an automobile factory. Among the 1,223 men seen, representing 97% of the sample, the prevalence of non-infective skin diseases was 14·5%. Skin diseases were classified into four groups: `dermatitis' and `folliculitis' of occupational origin, endogenous `eczemas', and miscellaneous skin diseases. Slightly more than half of all the skin diseases seen were considered to be occupational in origin. In this population the prevalence of skin disease was more than four times that based on patients attending the factory medical department. An unsuspected cause of allergic dermatitis was found on the assembly lines, where the incidence of dermatitis was significantly higher than among the non-production workers. The prevalence of folliculitis was significantly higher among production than non-production workers. There was no significant difference in the prevalence of `eczema' or the miscellaneous skin diseases in the various occupational groups. Among European workers fair men were more prone to skin disease than darker men. In another factory, a West Indian and Asiatic group of workers had a significantly lower prevalence of skin diseases than a group of Europeans doing similar work. Folliculitis was more prevalent among the younger workers and those recently employed in the factory; there was no obvious association between age and length of service and the occurrence of other types of skin disease.

Vulnerability to Human Immunodeficiency Virus (HIV) infection among factory workers is a global problem. This study investigated the effectiveness of an intervention to increase AIDS knowledge, perceived accessibility to condoms and condom use among young factory workers in Thailand. The intervention was a workplace program designed to engage the private sector in HIV prevention. A cross-sectional survey conducted in 2008 to measure program outcomes in factories in Thailand was used in this study. The workplace intervention included the development of policies for management of HIV-positive employees, training sessions for managers and workers, and distribution of educational materials and condoms. A multi-level analysis was used to investigate the effect of HIV/AIDS prevention program components at the workplace on HIV/AIDS knowledge, perceived accessibility to condoms and condom use with regular sexual partners among 699 young factory workers (aged 18-24 years), controlling for their individual socio-demographic characteristics. Interventions related to the management and services component including workplace AIDS policy formulation, condom services programs and behavioral change campaigns were found to be significantly related to increased AIDS knowledge, perceived accessibility to condoms and condom use with regular partners. The effect of the HIV/AIDS training for managers, peer leaders and workers was positive but not statistically significant. With some revision of program components, scaling up of workplace interventions and the engagement of the private sector in HIV prevention should be seriously considered.

HIV/AIDS has become a full-blown development crisis affecting all sectors of the economy in most developing countries. Its social and economic consequences are felt widely not only in health but in education, industry, agriculture as well as transport. The study attempted to estimate the changes in worker's output and attendance associated with advancing HIV infection, and direct costs incurred by a fiber products factory due to illness and death related to HIV/AIDS. The study is a retrospective cohort with accounting method of cost estimation. The study subjects were factory workers enrolled in a cohort study of HIV incidence and progression in Akaki, Ethiopia since February 1997. The mean incentive earnings were not significantly different between HIV positives and negatives at baseline (in 1997). However, in the following years (1998, 1999 and 2000) the incentive earnings of HIV positives were significantly lower than the incentive earnings of HIV negatives. Trend analysis showed that advancing HIV infection, as measured by drop in CD4 count and increasing viral load, is associated with reduction in productivity and increased sick leave days. The study has shown that there is a direct negative impact of HIV infection on the productivity of factory workers and recommends institution of ART centers and programs in work places to mitigate the socio economic impact of the pandemic.

Potential health effects related to wood dust from the rubber tree, which produces natural rubber latex, have not been previously investigated. The main aim of this study was to investigate the relations of rubber tree dust exposure to respiratory and skin symptoms, asthma and lung function. A cross-sectional study was conducted among 103 workers (response rate 89%) in a rubber tree furniture factory and 76 office workers (73%) in four factories in Thailand. All participants answered a questionnaire and performed spirometry. Inhalable dust levels were measured in different work areas. Factory workers showed increased risk of wheezing, nasal symptoms and asthma compared to office workers. There was a dose-dependent increase in wheeze and skin symptoms in relation to dust level. Significantly increased risks of nasal symptoms (adj OR 3.67, 95% CI 1.45 to 9.28) and asthma (8.41, 1.06 to 66.60) were detected in the low exposure category. Workers exposed to ethyl cyanoacrylate glue had significantly increased risk of cough, breathlessness and nasal symptoms. There was dose-dependent reduction in spirometric lung function with wood dust level. This study provides new evidence that workers exposed to wood dust from the rubber tree experience increased risk of nasal symptoms, wheeze, asthma and skin symptoms and have reduced spirometric lung function. Exposure to cyanoacrylate is related to significantly increased respiratory symptoms. Results suggest that the furniture industry using rubber tree wood should implement appropriate exposure control measures to reduce wood dust exposure and cyanoacrylate glue exposure to protect their employees.

The number of foreign workers in Japan, especially temporary workers, has been increasing recently. However, little is known about the mental health status of the foreign workers working temporarily in Japan. We examined the depressive symptoms in 81 Chinese factory workers and attempted to identify the determining factors. The subjects were requested to complete individual questionnaires on sociodemographic variables (sex, age group, and residence period in Japan), working condition variables (number of working days per week and working hours per day), health administration variables (health checkups and health education), a social support variable (interpreters at workplace), and health behavior variables (alcohol consumption, current smoking, and regular exercise). The 20-item Center for Epidemiologic Studies Depression scale (CES-D) was used to measure the depressive symptoms. Of all the subjects, 95% and 84% received health checkups and health education, respectively, at their workplaces. The results of multiple linear regression analysis showed that long working hours per day were significantly associated with high CES-D score. Further, we found that older age (30-49 yr) was marginally associated with high CES-D score. Health administration considering working time and age would be important for decreasing depressive symptoms among foreign workers.

Reports on the cardiorespiratory fitness and body composition of male workers engaged in processing of tea leaves in factories within the tea-estates of West Bengal, under the influence of physiological workload, are quite scanty. This cross-sectional study was conducted to evaluate morphometric characteristics based on physiological status and physical fitness of tea factory laborers who are continuously exposed to tea dust in their work environment for more than two years. Subjects were divided into control and tea garden workers groups. Height and weight were measured and the body mass index (BMI) was computed. Physiological parameters such as resting heart rate, blood pressure, fitness variables like physical fitness index (PFI), energy expenditure (EE), handgrip strength and anthropometric parameters like mid-upper arm (MUAC), thigh circumference (TC), head circumference (HC) and waist-to-hip ratio (WHR) were measured. Body surface area (BSA), BMI, body fat percentage and fitness variables (PFI, EE) showed significant difference (p < 0.05) between the two groups. Anthropometric measures (MUAC, TC, HC, WHR) reflected poor status among laborers. The present study shows that the majority of workers had ectomorph stature, good physical fitness, but had poor nutritional status (BMI and WHR).

The role of psychosocial and physical work factors in predicting health related quality of life (HRQOL) has not been investigated among Iranian industrial workers. The present study is designed to assess these relationships among Iranian workers from steel and cosmetic factories. A cross-sectional study was conducted among 280 workers from two factories. Psychosocial and physical work factors and HRQOL were measured by the Persian translations of the following questionnaires: Job Content Questionnaire (JCQ) and the World Health Organization Quality of Life-Brief (WHOQOL-Brief). An instrument was developed to assess socio-demographic, health, and other work-related factors. The data were analyzed using independent t-tests, Pearson product moment correlation and hierarchical multiple regression. Results revealed that the respondents generally had poor HRQOLs especially in the environmental domain. The steel factory workers who were exposed to higher levels of occupational risk factors suffered from poorer HRQOL compared to the cosmetic factory workers. The results of hierarchical regression for all participants revealed that social support, sleep quality, work schedule, smoking and exercise were significant predictors of all domains of HRQOL. To improve the worker's HRQOL, intervention programs should focus on promoting social support, sleep quality, exercise and smoking habits. Moreover, reducing hazardous work environments should be considered an important intervention to promote HRQOL.

Lifestyle factors, sometimes associated with physical health and mortality, have also been known to be associated with mental health status. This study seeks to correlate behavioral lifestyles with major components of mental health among Japanese factory workers. We administered the 28-item version of the General Health Questionnaire (GHQ-28) and a questionnaire concerning eight personal health practices to 2,132 male and 668 female factory workers at a camera-manufacturing company in Japan. There were strong negative relationships of a higher total number of favorable lifestyles as indicated by the Health Practice Index (HPI) to psychological distress and its components: somatic symptoms, anxiety-insomnia, and social dysfunction. After controlling for the effects of confounding factors that included age, marital status, and somatic condition, multiple logistic regression analysis indicated that five of the eight health factors among male workers--mental stress, nutritional balance, eating breakfast regularly, physical exercise, and working hours--were significantly related to the grade of psychological distress or its three components. Among female workers, five health practices, i.e., mental stress, physical exercise, sleeping hours, working hours, and cigarette smoking, were significantly associated with the grade of psychological distress or its three components. Good health practices might be individually and as a whole associated with better mental health status in factory workers.

Occupational asthma in electronics workers caused by colophony fumes: follow-up of affected workers.

PubMed

Burge, P S

1982-05-01

Thirty-nine electronics workers were investigated by bronchial provocation testing to soldering fluxes containing colophony and were followed up one to four years later. At presentation and on follow-up each worker had nonspecific bronchial reactivity measured with inhaled histamine, and also had detailed measurements of lung function and estimation of total immunoglobulin levels. They completed a questionnaire designed to detect residual disability. The workers were divided into three groups. Twenty had left work after their initial diagnosis, eight had been moved to alternative work within their original factories, and 11 were thought to have asthma unrelated to colophony exposure as they failed to react to colophony at presentation. Histamine reactivity had returned to normal in half the workers who had left their original factories, but in only one worker who had moved within her original factory. This suggested that the nonspecific bronchial reactivity to histamine was the result rather than the cause of the occupational asthma, and that indirect exposure at work was sufficient to delay recovery of histamine reactivity. However, only two of the 20 affected workers who had left their original factories were symptom free on follow-up, and most had a considerable reduction in their quality of life by continuing asthma, which was particularly provoked by exercise, respiratory infections, and nonspecific irritants. Continuing symptoms may have been caused by domestic sources of colophony, or possibly the failure to eliminate colophony from the lungs.

Many workers suffer from low-back pain. Type and severity of spinal complaints have relationship with work load. Lack of adherence to ergonomics recommendations among the important causes of low-back pain. To assess the effect of 3 ergonomics training programs on the prevalence of lowback pain among workers of an Iranian automobile factory. In a parallel-design 4-arm randomized clinical trial, 760 active workers of an automobile factory were studied. 503 workers were found eligible and randomized into 3 intervention groups (n=252), and a control group (n=251). The intervention groups consisted of 3 arms: 84 workers were educated by pamphlet, 84 by lectures, and 84 by workshop. Nordic questionnaire was used to determine the prevalence of spinal complaint before and 1-year after the interventions. The trial is registered with the Iranian Randomized Clinical Trial Registry, number IRCT2013061213182N2. Out of 503 workers, 52 lost to follow-up leaving 451 workers for analyses. The prevalence of low-back pain at the baseline was not significantly different among the studied arms. 1-year after the interventions, the prevalence did not change significantly from the baseline values for the lecture and pamphlet group. However, the prevalence of LBP experienced during the last year significantly (p=0.036) decreased from 42% to 23% in participant took part in the workshop. Training of automobile factory workers in ergonomics is more effective by running workshop than giving lecture or disseminating pamphlet.

Fifty-three workers in a battery factory, 52 solderers in a television factory, and 50 embroidery workers (a reference group) were studied. The average air lead levels of the three workplaces were 0.578 mg/m3, 0.002 mg/m3, and 0.001 mg/m3, respectively. Adverse effects in terms of clinical manifestations and biochemical criteria were evident among the battery factory workers. A significant dose-response relationship existed between the toxic effects and the air lead levels. The solderers showed no apparent abnormalities in comparison with the embroidery workers. The early clinical manifestations were dysfunction of the central nervous system, indigestion, arthralgia, and myalgia in the extremities. A positive association was observed between the prevalence of fatigue, mild abdominal pain, and arthralgia and the blood lead (PbB), urinary lead (PbU), and zinc protoporphyrin (ZPP) levels. The symptomatic threshold values of PbB, PbU, and ZPP were 30 micrograms/dl (1.5 mumol/l), 0.045 mg/l (0.2 mumol/l), and 40 micrograms/dl (0.7 mumol/l), respectively. The PbB, PbU, free erythrocyte protoporphyrin, and ZPP levels and the blood aminolevulinic dehydratase ratio could be used as indicators of lead exposure, although ZPP is preferred for a preventive monitoring program. The motor and sensory conduction velocities of the median nerve were slower in the exposed groups than in the reference group. No effects on behavioral function were observed among the solderers.

Between 1958 and 1982, NL Industries manufactured components of enriched (EU) and depleted uranium (DU) at a factory in Colonie NY, USA. More than 5 metric tons of DU was deposited as microscopic DU oxide particles on the plant site and surrounding residential community. A prior study involving a small number of individuals (n=23) indicated some residents were exposed to DU and former workers to both DU and EU, most probably through inhalation of aerosol particles. Our aim was to measure total uranium [U] and the uranium isotope ratios: (234)U/(238)U; (235)U/(238)U; and (236)U/(238)U, in the urine of a cohort of former workers and nearby residents of the NLI factory, to characterize individual exposure to natural uranium (NU), DU, and EU more than 3 decades after production ceased. We conducted a biomonitoring study in a larger cohort of 32 former workers and 99 residents, who may have been exposed during its period of operation, by measuring Total U, NU, DU, and EU in urine using Sector Field Inductively Coupled Plasma - Mass Spectrometry (SF-ICP-MS). Among workers, 84% were exposed to DU, 9% to EU and DU, and 6% to natural uranium (NU) only. For those exposed to DU, urinary isotopic and [U] compositions result from binary mixing of NU and the DU plant feedstock. Among residents, 8% show evidence of DU exposure, whereas none shows evidence of EU exposure. For residents, the [U] geometric mean is significantly below the value reported for NHANES. There is no significant difference in [U] between exposed and unexposed residents, suggesting that [U] alone is not a reliable indicator of exposure to DU in this group. Ninety four percent of workers tested showed evidence of exposure to DU, EU or both, and were still excreting DU and EU decades after leaving the workforce. The study demonstrates the advantage of measuring multiple isotopic ratios (e.g., (236)U/(238)U and (235)U/(238)U) over a single ratio ((235)U/(238)U) in determining sources of uranium exposure.

Today, many raw materials used in factories may have a dangerous effect on the physiological system of workers. One of them which is widely used in the polyurethane factories is diisocyanates. These compounds are widely used in surface coatings, polyurethane foams, adhesives, resins, elastomers, binders, and sealants. Exposure to diisocyanates causes irritation to the skin, mucous membranes, eyes, and respiratory tract. Hexamethylene diamine (HDA) is metabolite of hexamethylene diisocyanate (HDI). It is an excretory material by worker's urine who is exposed to HDI. Around 100 air samples were collected from five defined factories by midget impinger which contained dimethyl sulfoxide absorbent as a solvent and tryptamine as reagent. Samples were analyzed by high-performance liquid chromatography with EC\\UV detector using NIOSH 5522 method of sampling. Also, 50 urine samples collected from workers were also analyzed using William's biological analysis method. The concentration of HDI into all air samples were more than 88 microg/m(3), and they have shown high concentration of pollutant in the workplaces in comparison with NIOSH standard, and all of the workers' urine were contaminated by HDA. The correlation and regression test were used to obtain statistical model for HDI and HDA, which is useful for the prediction of diisocyanates pollution situation in the polyurethane factories.

The main objectives of this cross-sectional descriptive study were to identify the prevalence of musculoskeletal symptoms and workstation biomechanical risk levels for garment workers in Kandal Province, Cambodia. This cross-sectional descriptive study used multistage sampling techniques to select 714 workers from three garment factories among 22 medium-size factories (250-1,000 workers). Face-to-face interviews and direct observation using the rapid upper limb assessment scale (RULA) were used to collect data. The response rate was 98.3% (702/714), and the majority (89.3%) of the respondents were female. Ninety-two percent (95% CI=90.0-94.0) of the workers reported musculoskeletal symptoms in at least one body region in the previous 12 months and 89.0% (95% CI=86.7-91.3) of the workers reported such symptoms in the past seven-day period. The neck, shoulder, and lower back were the most affected body regions. In addition, the RULA data showed that 81.2% of the workers' postures were rated as action level 3, indicating that investigation and change were required soon, and that 7.5% their postures were rated as action level 4, indicating that investigation and change were required immediately. Cambodian garment workers reported a high prevalence of musculoskeletal symptoms in upper body regions, and their workplaces were rated as high risk ergonomically.

Occupational exposure to cotton dust, fibers, metal fumes and different chemicals used in the aparrel manufacturing industries cause a wide range of physical and psychological health problems in the garment workers that may also affect their immune function. To assess the immune system function in garment workers. A total of 45 workers of a garment factory, and 41 control subjects, not exposed to the garment working environment were enrolled in this study. In the study subjects, the complement system function was assessed as bactericidal activity on Escherichia coli DH5α cells using the standard plate count method. Serum complement components C3 and C4 were measured by immunoprecipitation, and IgG was measured by immunonephelometry. The bactericidal activity of serum complement in the garment workers (range: 93.5%-99.9%) was significantly (p<0.01) lower than that in the controls (range: 98.6%-100%). The heat-inactivated serum of the workers showed a significantly enhanced bactericidal activity. In the garment workers, the mean levels of complement C3, and C4 were 1.75 and 0.26 g/L, respectively that were close to those of the controls. The mean IgG level in the garment workers was 13.5 g/L that was significantly (p<0.001) higher than that in the controls. Working in a garment factory may affect the immune system.

The main objective of this study is to assess the health hazards due to radon gas accumulation and to compare the concentrations in different kinds of workplaces, in the city of Adapazarı, one of the most important industrial cities of Turkey. For this purpose, radon activity concentration measurements were carried out in schools, factories, offices and outdoors using CR-39 solid state nuclear track detectors (SSNTD). Results show that the mean radon activity concentrations (RAC) in schools, offices and factories were found to be 66, 76 and 27 Bq/m3, respectively, with an outdoor concentration of 14 Bq/m3. The average concentrations were found to decrease as follows for different types of industries: automotive > electronic > metal > textile. Because the maximum measured radon concentrations are 151 Bq/m3 in the schools, 173 Bq/m3 in the offices and 52 Bq/m3 in the factories, the limits of ICRP are not exceeded in any of the buildings in the region. In addition, the estimated mean annual effective doses to the people in the workplace, students, office workers and factory workers have been calculated as 0.27, 0.63 and 0.20 mSv/y, respectively for the region.

As a first step in designing an AIDS prevention program at a large factory in Kinshasa, Zaire, we collected information on attitudes towards human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS) from factory foremen and their wives. Trained moderators conducted twelve focus group discussions (from November through December 1987) that addressed knowledge, attitudes and beliefs about HIV infection and AIDS. In general, participants were familiar with HIV infection and AIDS and considered these conditions leading health problems in Kinshasa. Although participants had a fairly accurate understanding of the causes of HIV infection, modes of transmission and preventive measures, many myths and misconceptions existed. Many participants did not believe that condom use would consistently prevent infection through sexual intercourse. Participants strongly favored the counseling of seropositive persons but showed less consensus about whether the spouse of a seropositive person should be notified of the partner's test result. Participants predicted that couples in which one member is seropositive and the other is not would experience marital discord and friction with family, neighbors and co-workers. These findings were applied to the development of a counseling and educational program for seropositive factory employees and their spouses.

Glass factory workers are often exposed to the hazardous environment that leads to deleterious oral health and subsequently, general health. We planned to determine the effects of the particulates present in the milieu on the tooth wear among workers. To assess tooth wear among glass factory workers in Jaipur, Rajasthan, India. A descriptive cross-sectional survey was conducted among 936 glass workers in Jaipur, Rajasthan, India from January-June 2014. A survey proforma was designed for tooth wear evaluation with the help of WHO Oral Health Assessment form 2013 (for adults). Information regarding oral health practices, adverse habits and dietary habits, demographic details was gathered and clinical parameters were recorded. The Chi-square test, t-test, One-way Analysis of Variance and a Stepwise multiple linear regression analysis. The most prevalent form of erosion was enamel erosion (589, 62.93%) with few subjects of deeper dentinal erosion and the difference was statistically significant (p=0.001). Dental erosion was found to be higher among males compared to females. Years of experience and educational status were identified as best predictors for dental erosion. It was concluded that there was considerable evidence of dental erosion found among the factory workers. Due to ignorance on social, cultural and health aspects, professional approach with regular dental care services for detection of early symptoms and planning of preventive strategies is warranted.

Job strain has become a major concern because of its potential impacts on worker well-being and performance. This cross-sectional study aimed to assess the prevalence of, and examine factors associated with, job strain among workers in a rubber-glove factory, in a central province of Thailand. A total of 200 workers aged 18-55 yr, who had worked at the factory for at least 6 months, completed the Job Content Questionnaire (JCQ) (Thai Version). Two of 5 scales in the JCQ were used to measure job strain, i.e.; job control and psychological job demand. The prevalence of job strain was 27.5%. Multiple logistic regression analysis indicated two variables significantly associated with job strain: low supervisor social support (adjusted OR=3.08; 95%CI: 1.38-6.91) and high job insecurity (adjusted OR=2.25; 95%CI: 1.04-4.88). Effective training for supervisors, to create good relationships among workers and supervisors, and ensuring steady and secure jobs for good employees, are necessary.

Study of two cohorts of workers exposed to methyl methacrylate in acrylic sheet production

OBJECTIVES—To study mortality among 4324 workers at two United Kingdom factories, Darwen, Lancashire and Wilton, Cleveland, producing polymethyl methacrylate (PMMA) sheet. The Darwen factory is still active, but the Wilton one was closed in 1970. Also, to investigate patterns of mortality after exposure to methyl methacrylate; in particular, mortality from colon and rectal cancer.
METHODS—All male employees at the Darwen factory with a record of employment in 1949-88 and all men ever employed at the Wilton factory (1949-70) were investigated. The vital status of both cohorts was ascertained on 31 December 1995. The exposure of 1526 subjects at the Darwen plant who were engaged from 1949 onwards could be characterised. The mean duration of exposure was 7.6 years at 13.2 ppm (8 hour time weighted average), although exposures in some work groups were as high as 100 ppm. It was not possible to calculate the cumulative exposure of workers first employed at the Darwen plant before 1949 or workers at the Wilton factory.
RESULTS—In the Darwen cohort, 622 deaths were identified and a further 700 deaths in the Wilton cohort. Mortalities for the cohort were compared with national and local rates and expressed as standardised mortality ratios (SMRs). In the subcohort of Darwen workers with more than minimal exposure to MMA, reduced mortalities compared with national and local rates, were found for all causes (SMR 94), and colorectal cancer (SMR 92), but mortality from all cancers was slightly increased (SMR 104). No relations were found with cumulative exposure to MMA. In the subcohort of Wilton workers, mortality from all causes of death was significantly reduced (SMR 89), but mortality from all cancers (SMR 103) and colorectal cancer (SMR 124) were increased. The excess of colorectal cancer was confined to employees with less than 1 year of employment.
CONCLUSION—The study provided no clear evidence that employment at the factories or exposure to MMA had adversely affected the mortalities of workers.

The main aim of the study was to propose a model for predicting the peak expiratory flow rate (PEFR) of Nigerian workers in a cement factory. Sixty randomly selected non-smoker and healthy workers (30 in production sections, 30 in the administrative section of the factory) participated in the study. Their physical characteristics and PEFR were measured. Multiple correlations using SPSS version 16.0 were performed on the data. The values of PEFR, using the obtained model, were compared with the measured values using a two-tailed t test. There were positive correlations among age, height and PEFR. A prediction equation for PEFR based on age, height, weight and years of exposure (experience) was obtained with R² = .843 (p < 0.001). The developed model will be useful for the management in determining PEFR of workers in the cement industry for possible medical attention.

Titanium dioxide (TiO2) particles are used for surface coating and in a variety of products such as inks, fibers, food, and cosmetics. The present study investigated possible respiratory and cardiovascular effects of TiO2 particles in workers exposed to this particle at high concentration in a factory in China. The diameter of particles collected on filters was measured by scanning electron microscopy. Real-time size-dependent particle number concentration was monitored in the nostrils of four workers using condensation particle counter and optical particle counter. Electrocardiogram was recorded using Holter monitors for the same four workers to record heart rate variability. Sixteen workers underwent assessment of the respiratory and cardiovascular systems. Mass-based individual exposure levels were also measured with personal cascade impactors. The primary particle diameter ranged from 46 to 562 nm. Analysis of covariance of the pooled data of the four workers showed that number of particles with a diameter <300 nm was associated positively with total number of N-N and negatively with total number of increase or decrease in successive RR intervals greater than 50 ms (RR50+/-) or percentage of RR 50+/- that were parameters of parasympathetic function. The total mass concentration was 9.58-30.8 mg/m3 during work, but significantly less before work (0.36 mg/m3). The clear abnormality in respiratory function was not observed in sixteen workers who had worked for 10 months to 13 years in the factory. The study showed that exposure to particles with a diameter <300 nm might affect HRV in workers handling TiO2 particles. The results highlight the need to investigate the possible impact of exposure to nano-scaled particles on the autonomic nervous system.

“Habits of employees”: smoking, spies, and shopfloor culture at Hammermill Paper Company.

PubMed

Wood, Gregory

2011-01-01

As cigarette smoking expanded dramatically during the early twentieth century, it brought more and more workers into conflict with the policies and demands of the manufacturers who employed them. As this paper shows, addiction to nicotine ignited daily struggles over workers’ shopfloor rights and the ability of employers to set rules, establish discipline, and monitor behavior. A specific set of records from the archives of the Hammermill Paper Company, a paper manufacturer once based in Erie, Pennsylvania, provide a unique opportunity to explore the impact of cigarette consumption on labor relations during the era of mass production, as two nosy factory spies probed and documented worker actions and attitudes in the summer of 1915. As a result of their intelligence gathering, the spies discovered a factory-wide work culture rooted in the addictive pleasure of cigarette smoke. This discovery worried them. Worker-smokers needed to dampen their hunger for nicotine with frequent, and often clandestine, breaks from work, typically in defiance of “no-smoking” rules, employer designations for the uses of factory space, and bosses’ demands for continuous production. Highlighting the intersections of the histories of labor, smoking, and addiction, this paper argues that cigarettes were a key battleground in workers’ and managers’ intensifying struggles over who really controlled the industrial shopfloor during the early 1900s.

A Q fever outbreak was declared in February 2016 in a company that manufactures hoists and chains and therefore with no apparent occupational-associated risk. Coxiella burnetii infection was diagnosed by serology in eight of the 29 workers of the company; seven of them had fever or flu-like signs and five had pneumonia, one requiring hospitalisation. A further case of C. burnetii pneumonia was diagnosed in a local resident. Real-time PCR (RTi-PCR) showed a widespread distribution of C. burnetii DNA in dust samples collected from the plant facilities, thus confirming the exposure of workers to the infection inside the factory. Epidemiological investigations identified a goat flock with high C. burnetii seroprevalence and active shedding which was owned and managed by one of the workers of the company as possible source of infection. Genotyping by multispacer sequence typing (MST) and a 10-loci single-nucleotide polymorphism (SNP) discrimination using RTi-PCR identified the same genotype (MST18 and SNP type 8, respectively) in the farm and the factory. These results confirmed the link between the goat farm and the outbreak and allowed the identification of the source of infection. The circumstances and possible vehicles for the bacteria entering the factory are discussed.

Behavioral determinants of occupational exposure to chemical agents.

Meijman, T F; Ulenbelt, P; Lumens, M E; Herber, R F

1996-01-01

In the demand-control model (see T. Theorell & R. A. Karasek, 1996), it is hypothesized that workers in active jobs (high demands-high decision latitude) can exert effective coping strategies when confronted with environmental stessors. Thus, when exposed to similar levels of a chemical agent, lower concentrations of this agent in blood could be expected in these workers in comparison with workers in passive jobs. This theory was tested in 2 studies of lead-exposed workers: 18 male Caucasian workers from an electric accumulatory factory and 18 male Caucasian workers from a lead smelting factory. The results did not follow the hypothesized outcomes. In the work environment of the workers in active jobs, lower concentrations of lead in air were measured, but higher levels of lead in blood were observed in these workers. The opposite was true of workers in passive jobs. Differences in hygienic behavior at work may explain these unexpected results.

A sociomedical survey of 975 workers employed in an electronic instrument factory was carried out by standardized interview and aimed at defining the relationship between some psychosocial working conditions and the occurrence of headaches. The findings showed different patterns of headaches in specific occupational categories with workers exposed to different psychosocial stresses. Headaches were more frequent in those who became nervous during their work, those who were often in conflict with their co-workers, and those holding managerial posts.

The seafood processing industry has been developing and providing marked contribution to Vietnam's economic growth in recent years. However, information on working conditions and their impacts to workers' health in this sector, focusing on musculoskeletal problems in female workers, has been poorly documented. This paper examines the prevalence of after-shift musculoskeletal disorder symptoms (A-MSDS) and work-related factors in female workers in a seafood processing factory in Vietnam. As part of a comprehensive study, a cross-sectional survey was implemented in one seafood processing factory in the center of Vietnam in 2014. A self-administered questionnaire was completed by 394 female workers to collect information about their A-MSDS state, demographic characteristics, health status and work conditions. Descriptive analysis and logistic regression were applied to describe and analyse the results. Nearly four-fifths of female workers experienced MSDs in at least one body part (77.7%) and 20.1% of them had MSDs in all investigated regions. The prevalence of A-MSDS in different body parts markedly varied, with the proportion of pain in the hips and lower extremities being as high as 53.3%, followed by pain in the shoulders and upper extremities (42.6%) and the neck (41.1%). A humid working environment, exposure to vibration and chemicals as well as taxing task demands and work organizations were found to significantly contribute to the increased risk of after-shift musculoskeletal disorders in female workers. Approximately 80% of female workers in the seafood processing factory experienced musculoskeletal pains after work, especially in the hips, extremities, neck and shoulders which were contributed by work conditions and task demands.

Study recommends measures to reduce induced abortion among young women in the Republic of Korea.

PubMed

1994-01-01

A study supported by the Program in the Republic of Korea involved 500 unmarried female adolescents and young adults selected from three categories: (a) factory workers living in industry-affiliated housing who participated in the project's special information program; (b) entertainers and sex workers working in bars and similar enterprises; and (c) women who sought an induced abortion in hospitals or private clinics. The average age of the women in each group was 22 years, 23 years, and 24 years, respectively. Most of the women had 12 years of schooling or more, and reported that their ideal age to enter marriage was 25 years. Korean society is generally very traditional, but among the factory workers cohabitation by unmarried couples is quite common and is gaining social acceptance. Among the women who reported a previous unwanted pregnancy, 85% said that they had not used a contraceptive before. Among the sex workers, contraceptive use was 53%, but still 66% had had an unwanted pregnancy. Among the factory workers contraceptive prevalence was 21%, and 36% reported having had an unwanted pregnancy. Among those seeking an abortion, only 20% had been using a method at the time of conception with 15% reporting contraceptive failure. Previous abortion experience was highest among abortion seekers (76%), followed by sex workers (45%), and the factory workers (11%). An argument is made for legalization of abortion in the country given that most abortions take place under unsafe conditions. Sex education is also recommended in schools and making family planning services available to adolescents, particularly to single women working in the industrial sector. The results have been discussed with labor unions and workers' organizations.

To investigate the occupational hazards among Chinese female workers in the electronics industry, the authors systematically sampled a total of 8,300 female workers at random across 4 provinces in a variety of electronics factories. A detailed questionnaire was used to collect information on occupational hazards and the occurrence of occupation-related diseases. The results show that 4,283 female workers (51.9%) were exposed to 1 or more occupational hazards. The most common chemical hazard was organic solvent, and the second most common was heavy metals. The ergonomic hazards included repetitive movements, poor standing posture, and the lifting of heavy goods. More than 60% of the female workers self-reported occupation-related diseases. These results showed that occupational health hazards were common in the electronics industry in China and that they caused serious occupation-related health problems for the female workers therein.

Background Glass factory workers are often exposed to the hazardous environment that leads to deleterious oral health and subsequently, general health. We planned to determine the effects of the particulates present in the milieu on the tooth wear among workers. Aim To assess tooth wear among glass factory workers in Jaipur, Rajasthan, India. Settings and Design A descriptive cross-sectional survey was conducted among 936 glass workers in Jaipur, Rajasthan, India from January-June 2014. Materials and Methods A survey proforma was designed for tooth wear evaluation with the help of WHO Oral Health Assessment form 2013 (for adults). Information regarding oral health practices, adverse habits and dietary habits, demographic details was gathered and clinical parameters were recorded. Statistical Analysis The Chi–square test, t–test, One-way Analysis of Variance and a Stepwise multiple linear regression analysis. Results The most prevalent form of erosion was enamel erosion (589, 62.93%) with few subjects of deeper dentinal erosion and the difference was statistically significant (p=0.001). Dental erosion was found to be higher among males compared to females. Years of experience and educational status were identified as best predictors for dental erosion. Conclusion It was concluded that there was considerable evidence of dental erosion found among the factory workers. Due to ignorance on social, cultural and health aspects, professional approach with regular dental care services for detection of early symptoms and planning of preventive strategies is warranted.

Depleted and enriched uranium exposure quantified in former factory workers and local residents of NL Industries, Colonie, NY USA

DOE Office of Scientific and Technical Information (OSTI.GOV)

Arnason, John G.

Background: Between 1958 and 1982, NL Industries manufactured components of enriched (EU) and depleted uranium (DU) at a factory in Colonie NY, USA. More than 5 metric tons of DU was deposited as microscopic DU oxide particles on the plant site and surrounding residential community. A prior study involving a small number of individuals (n=23) indicated some residents were exposed to DU and former workers to both DU and EU, most probably through inhalation of aerosol particles. Objectives: Our aim was to measure total uranium [U] and the uranium isotope ratios: {sup 234}U/{sup 238}U; {sup 235}U/{sup 238}U; and {sup 236}U/{supmore » 238}U, in the urine of a cohort of former workers and nearby residents of the NLI factory, to characterize individual exposure to natural uranium (NU), DU, and EU more than 3 decades after production ceased. Methods: We conducted a biomonitoring study in a larger cohort of 32 former workers and 99 residents, who may have been exposed during its period of operation, by measuring Total U, NU, DU, and EU in urine using Sector Field Inductively Coupled Plasma - Mass Spectrometry (SF-ICP-MS). Results: Among workers, 84% were exposed to DU, 9% to EU and DU, and 6% to natural uranium (NU) only. For those exposed to DU, urinary isotopic and [U] compositions result from binary mixing of NU and the DU plant feedstock. Among residents, 8% show evidence of DU exposure, whereas none shows evidence of EU exposure. For residents, the [U] geometric mean is significantly below the value reported for NHANES. There is no significant difference in [U] between exposed and unexposed residents, suggesting that [U] alone is not a reliable indicator of exposure to DU in this group. Conclusions: Ninety four percent of workers tested showed evidence of exposure to DU, EU or both, and were still excreting DU and EU decades after leaving the workforce. The study demonstrates the advantage of measuring multiple isotopic ratios (e.g., {sup 236}U/{sup 238}U and {sup 235}U/{sup 238}U) over a single ratio ({sup 235}U/{sup 238}U) in determining sources of uranium exposure. - Highlights: • Biomonitoring study of residents and former workers exposed to DU in Colonie NY. • Urine (99 residents+32 former workers) analyzed for depleted uranium (DU). • DU detected in 84% of workers and 8% of residents >30 years after plant closed. • Enriched uranium detected in 6% of former workers based on isotope ratios.« less

To implement and evaluate a public-private partnership model involving garment factories to reduce the tuberculosis (TB) burden in this workforce. We used operational research to develop and evaluate a mechanism for effective and sustainable TB control in workplaces in three areas of Dhaka, Bangladesh. Strategies, protocols, guides and tools were developed with stakeholders. We assessed the impact of the project using quantitative and qualitative measures: changes in TB outcomes were calculated using standard indicators based on factory and DOTS centre records; changes in TB care-seeking behaviour were assessed using qualitative in-depth interviews with factory managers and medical personnel, and focus group discussions with factory workers, including TB patients. The project brought positive changes in knowledge, attitudes and practices of managers, workers and health care providers on TB care and control. During 2008-2010, a total of 3372 workers from a workforce of 69,000 were referred for sputum microscopy and 598 were diagnosed with smear-positive TB, 145 of whom received care at their workplace. The overall treatment success rate was 100%. It is feasible to engage factories in TB control activities in Bangladesh, and thereby increase case notifications and improve treatment outcomes.

To assess the prevalence of musculoskeletal symptoms and their association with sociodemographic risk factors among female garment factory workers in Sri Lanka. 1058 randomly selected female garment factory workers employed in the free trade zone of Kogalla, Sri Lanka were recruited to complete two interviewer-administered questionnaires assessing musculoskeletal symptoms and health behaviors. Musculoskeletal complaints among female garment workers in the FTZ of Kogalla are less common than expected. Sociocultural factors may have resulted in underreporting and similarly contribute to the low rates of healthcare utilization by these women. 164 (15.5%) of workers reported musculoskeletal symptoms occurring more than 3 times or lasting a week or more during the previous 12-month period. Back (57.3%) and knee (31.7%) were the most common sites of pain. Although most symptomatic women reported that their problems interfered with work and leisure activities, very few missed work as a result of their pain. Prevalence correlated positively with increased age and industry tenure of less than 12 months. Job type, body mass index, and education were not significant predictors of musculoskeletal symptoms.

Baby factories taint surrogacy in Nigeria.

2016-01-01

The practice of reproductive medicine in Nigeria is facing new challenges with the proliferation of 'baby factories'. Baby factories are buildings, hospitals or orphanages that have been converted into places for young girls and women to give birth to children for sale on the black market, often to infertile couples, or into trafficking rings. This practice illegally provides outcomes (children) similar to surrogacy. While surrogacy has not been well accepted in this environment, the proliferation of baby factories further threatens its acceptance. The involvement of medical and allied health workers in the operation of baby factories raises ethical concerns. The lack of a properly defined legal framework and code of practice for surrogacy makes it difficult to prosecute baby factory owners, especially when they are health workers claiming to be providing services to clients. In this environment, surrogacy and other assisted reproductive techniques urgently require regulation in order to define when ethico-legal lines have been crossed in providing surrogacy or surrogacy-like services.

2011-11-01

The aim of this study was to examine the factorial validity of the Job Expectations Questionnaire (Cuestionario de Expectativas Laborales CEL) in a sample of Mexican workers. Following a cross validation approach, two samples were used in the study. The first sample consisted of 380 professionals who mainly performed administrative work in the Health Services in Puebla-Mexico. The second sample comprised 400 health professionals from the Hospital de la Mujer in Puebla-Mexico. Exploratory factor analysis yielded a three-factor solution, accounting for 51.8% of the variance. The results of confirmatory factorial analysis indicate that the three-factor model provided the best fit with the data (CFI = .96, GFI = .95, NNFI = .95, RMSEA = .04), maintaining the structure with 12 items. The reliability of the questionnaire and the diverse subscales showed high internal consistency. Significant correlations were found between job expectations and autonomy, vigor, dedication, and absorption, providing evidence of its construct validity. The evaluation of the psychometric qualities confirms this questionnaire as a valid and specific instrument to measure job expectations.

To investigate risks to hard metal tool sharpeners, 80 factories in the Lombardia Region (North Italy) were selected and examined. The scope of the survey consisted of verifying and quantifying that risk, so as to be able to control it and reduce it as far as is possible. We singled out a group of 12 factories, comprising approximately 750 workers 60 of whom were exposed to cobalt, in which operations such as sharpening with diamond grinding stones are normally carried out. In those factories, the risk was quantified by determining the concentration of cobalt in dust, collected by means of personal and fixed samplers (23 measurements) during sharpening operations. The station had no local ventilation device; sharpening is mainly performed wet and has been found to present a greater risk than those where sharpening is exclusively performed dry. Results were confirmed by biological monitoring which showed the presence of cobalt excreted in exposed workers' urine collected at the end of the work shift.

In-Factory Learning - Qualification For The Factory Of The Future

Quint, Fabian; Mura, Katharina; Gorecky, Dominic

2015-07-01

The Industry 4.0 vision anticipates that internet technologies will find their way into future factories replacing traditional components by dynamic and intelligent cyber-physical systems (CPS) that combine the physical objects with their digital representation. Reducing the gap between the real and digital world makes the factory environment more flexible, more adaptive, but also more complex for the human workers. Future workers require interdisciplinary competencies from engineering, information technology, and computer science in order to understand and manage the diverse interrelations between physical objects and their digital counterpart. This paper proposes a mixed-reality based learning environment, which combines physical objects and visualisation of digital content via Augmented Reality. It uses reality-based interaction in order to make the dynamic interrelations between real and digital factory visible and tangible. We argue that our learning system does not work as a stand-alone solution, but should fit into existing academic and advanced training curricula.

[Health problems and illness of female workers in textile industries].

PubMed

Soonthorndhada, K

1989-07-01

This paper examines 3 major health-related issues: 1) existing health problems and illnesses resulting from physical environmental conditions at workplaces; 2) female workers' perception on illness and health protection; and 3) the relationship between illness and risk factors. The study area is textile factories in Bangkok and its peripheries. Data are drawn from the 1987 Survey of Occupational Health and Textile Industrial Development in Thailand: Effect on Health and Socioeconomics of Female Migrant Workers. This study shows that about 20% of female workers have ill-health problems and illness after a period of working mainly due to high levels of dust and noise, and inadequate light. These conditions are hazardous to the respiratory system (resulting in cough and chest tightness), the hearing system (pains as well as impaired and hearing loss), eye systems (irritation, reduced visual capacity) and skin allergy. Such illnesses are intensified in the long- run. The analysis of variances reveals that education, section of work, perception (particularly mask and ear plug) significantly affect these illnesses. This study concludes that health education and occupational health should be provided in factories with emphasis on health prevention and promotion.

Sexual behavior and perceived risk of HIV/AIDS among young migrant factory workers in Nepal.

PubMed

Puri, M; Cleland, J

2006-03-01

To analyze the sexual behavior, perceived risk of contracting STIs and HIV/AIDS, and protective behaviors of migrant workers aged 14-19 years in carpet and garment factories in the Kathmandu Valley, Nepal. A common assumption in Nepal is that young migrant workers experience an increase in vulnerability. Moving away from the social controls of family and community, they become exposed to a mixed-gender environment and therefore might initiate sex earlier or have more casual encounters than might otherwise be the case. The analysis is based on a representative sample survey of 1050 factory workers. Information was also obtained from 23 in-depth case histories. Both bivarite and multivariate techniques were applied to identify the factors associated with involvement in risky sexual behavior. Despite religious and cultural restrictions, one in five boys and one in eight unmarried girls reported experience of sexual intercourse. Early sexual experimentation, multiple partners, and low and irregular use of condoms are not uncommon. Instances of sexual exploitation by factory owners or managers were documented but were rare. Most nonregular sex partners were described as friends from the same factory or community. Despite high-risk behavior, relatively few young people considered themselves to be at risk of getting STIs or HIV/AIDS. Information on the possible consequences of unsafe sex is inadequate. Programs aimed at promotion of safer sex practices and life skill training that facilitates communication and utilization of sexual health services should target vulnerable migrant young people.

Most workers in auto part factories in Thailand are usually exposed to excessive noise in their workplace. This study aimed to assess the level of occupational noise-induced hearing loss and investigate risk factors causing hearing loss in auto part factory workers in the welding units in Thailand. This was a cross-sectional study. One hundred eighty subjects were recruited from 356 workers in the welding unit of three factories. Sixty eligible subjects in each factory were selected by systemic random sampling. The subjects were interviewed using a face-to-face questionnaire. Noise exposure levels and audiograms were measured by a noise dosimeter and an audiometer, respectively. The findings confirmed that noise exposure levels of 86-90 dB (A) and exceeding 90 dB (A) significantly increased the risk of hearing loss in either ear. A noise exposure level exceeding 90 dB (A) significantly increased the prevalence of hearing loss in both ears. Regarding, a 10-pack-year smoking history increased the prevalence of hearing loss in either ear or both ears. In addition, subjects with employment duration exceeding 10 years significantly developed hearing loss in either ear. The engineering control or personal control by wearing hearing protection device should be used to decrease noise exposure levels lower than 85 dB (A) for 8 h. Moreover, if the exposure level reaches 85 dB (A) for 8 h, the employer needs to implement a hearing conservation program in the workplace.

Follow up study of workers manufacturing chrysotile asbestos cement products.

1986-01-01

A cohort study has been carried out of 2167 subjects employed between 1941 and 1983 at an asbestos cement factory in England. The production process incorporated the use of chrysotile asbestos fibre only, except for a small amount of amosite during four months in 1976. Measured airborne fibre concentrations available since 1970 from personal samplers showed mean levels below 1 fibre/ml, although higher levels had probably occurred previously in certain areas of the factory. No excess of lung cancer was observed in the mortality follow up by comparison with either national or local death rates, and analyses of subgroups of the workforce by job, exposure level, duration of employment, duration since entry, or calendar years of employment gave no real suggestion of an asbestos related excess for this cause of death. There was one death from pleural mesothelioma and one with asbestosis mentioned as an associated cause on the death certificate, but neither is thought to be linked to asbestos exposure at this factory. Other suggested asbestos related cancers, such as laryngeal and gastrointestinal, did not show raised risks. Although the durations of exposure were short in this study, the findings are consistent with two other studies of workers exposed to low concentrations of chrysotile fibre in the manufacture of asbestos cement products which reported no excess mortality.

This study investigated the effects of working night shifts on social and family life by examining changes in workers' daily life before and after a change in their shifts. Subjects were 40 women aged 27-59 years, working at a dish factory. During the health examination of night workers in autumn of 2000, the subjects were directly interviewed about changes in their lives induced by the shift change. Question parameters consisted of 8 items including 30 sub-items related to social and family life, such as sleep, rest, meals, sports, family time, hobbies, neighborhood association and social activities. The subjects selected one of four response categories: "becoming worse", "no change", "becoming better" and "difficult to determine." With regard to the percentage of "becoming worse", meal-related items ranked high in all of the shift types. "Family time" and "hobbies" showed high percentages in the subjects transferring from day shifts to night shifts, and in those transferring from early-morning shifts to night shifts. "Rest", "sports" and "hobbies" showed high percentages in the subjects transferring from night shifts to midnight shifts. Decreased sleeping hours were confirmed in all of the shift types, while the subjects tended to sleep more soundly. As the workers transfer to shifts at earlier hours, they were obliged to make sacrifices in various aspects of their social and family life. Therefore, much assistance in this regard should be given to them.

To study the effect of occupational exposure, smoking, and drinking on lymphocyte DNA damage in bus manufacturing workers, 346 employees (106 women and 240 men) from six job categories (welders, mechanics, painters, and assembling, auxiliary and managerial workers) in a bus manufacturing factory in Guangzhou were included. Significant differences of tail moment among the six job categories were found (P=0.003) with adjustment for age and gender. Smoking increased tail moment significantly (3.14 (2.89-3.40) versus 2.79 microm (2.63-2.97), P=0.023). Analysis of covariance showed that occupational exposure (P=0.001) and smoking (P=0.019) had significant effect on tail moment after adjusting for all factors, whereas age and gender had no effect on DNA damage. Stratified analysis showed that painters (P=0.002), auxiliary workers (P=0.011), and mechanics (P=0.044) had larger tail moments than managerial workers after adjusting for age, gender, smoking, and drinking.

Global evidence demonstrates that inequitable gender norms negatively influence key health outcomes (e.g., violence, HIV/STI), and the importance of male involvement in prevention efforts. The China Family Planning Association and PATH partnered to develop and evaluate a gender-focused behavior change communication intervention for HIV and violence prevention. Eight participatory education sessions-adapted for the Chinese setting-were implemented in factories and schools. Baseline and endline surveys with participants (219 male factory workers and 496 male vocational students) were conducted. Support for (in)equitable norms was measured by the Gender Equitable Men Scale, as well as partner violence and communication. Focus groups with male and female workers/students, teachers, and factory managers were used to corroborate findings. At baseline, many workers and students supported inequitable gender norms, with workers generally being more inequitable. At endline, significant positive changes in gender-related views (e.g., reduction from 42% to 18% of workers agreeing that "a woman should tolerate violence in order to keep her family together") and behaviors (e.g., reduction from 15% to 7% of students reporting partner violence over the past 3 months) were reported. Results suggest that a relatively low intensity intervention can influence important gender norms and related behaviors.

The Majority of the Migrant Factory Workers of the Light Industry in Shenzhen, China May Be Physically Inactive.

Physical inactivity is a strong risk factor of non-communicable diseases (NCD). In China, there are 250 million migrant factory workers, who are susceptible to physical inactivity and hence NCD because of work nature and setting. With random stratified sampling, 807 such workers of the light industry were recruited in Shenzhen, China and completed a self-administered questionnaire with informed consent. The prevalence of inadequate physical activity (defined according to the World Health Organization's recommendation on level of moderate/vigorous physical activity) was 95.4%. Of all participants, 69.1% showed "a very low level of physical activity" (VLLPA), defined as ≤30 minutes of weekly moderate/vigorous physical activity, which was significantly associated with female sex (Odds ratio [OR]=1.65), lower education level (OR=0.10 to 0.33, primary education as the reference group) and married status (OR=0.63, single status as the reference group). Adjusted for these factors, perceived social support (Adjusted OR=0.87) was negatively associated with VLLPA, while job stress due to workload, which was significant in the univariate analysis (OR=0.98), became non-significant (p=0.184). Significant interaction between perceived social support and perceived job stress onto VLLPA was found (p=0.044), implying that the negative association between job stress and VLLPA, which might reflect a potential response to cope with stress by performing exercises, was stronger among those with weaker social support. The extremely low level of physical activity rings an alarm, as it implies high risk of NCD, and as there are no existing programs promoting physical activity in this group. Interventions need to take into account social support, potential coping to job stress, and structural factors of the factory setting, while involving factories' management.

Respiratory symptoms and pulmonary function were examined among 89 rubberwood furniture factory workers. Acute and chronic irritant symptoms were assessed, lung function was measured both pre- and post-shift and personal inhalable dust exposure determined. The only symptoms with a significant increase among high dust level-exposed workers (>1 mg/m(3)) were those related to nasal irritation. High dust level-exposed workers had a significant cross-shift decrease in forced expiratory volume in 1 second/forced vital capacity (FEV(1)/FVC) compared with low dust level-exposed workers and increases in inhalable dust concentration levels (mg/m(3)) were significantly associated with decreases in the peak expiratory flow (PEF) across the work shift. For percent predicted pulmonary function levels, a significant decrement in PEF was found for high versus low rubberwood dust level-exposed workers, after controlling for confounders. These findings suggest the need for an occupational standard for rubberwood dust in Thailand.

Incense and joss stick are generally used in the world. Most products were made in small household factories. There are many environmental and occupational hazards in these factories. To evaluate the workplace environmental and occupational hazards in small household incense and joss stick factories in Roi-Et, Thailand. Nine small household factories in rural areas of Roi-Et, Thailand, were studied. Dust concentration and small aerosol particles were counted through real time exposure monitoring. The inductively coupled plasma optical emission spectrometry (ICP-OES) was used for quantitative measurement of heavy metal residue in incense products. Several heavy metals were found in dissolved dye and joss sticks. Those included barium, manganese, and lead. Rolling and shaking processes produced the highest concentration of dust and aerosols. Only 3.9% of female workers used personal protection equipment. Dust and chemicals were major threats in small household incense and joss stick factories in Thailand. Increasing awareness towards using personal protection equipment and emphasis on elimination of environmental workplace hazards should be considered to help the workers of this industry.

1999-03-01

A two years retrospective analysis of patients diagnosed as contact allergic dermatitis with positive patch test attending the Dermatology clinic was performed. Of the 346 patients with a positive patch test, 14% had occupational dermatitis. This condition affected mainly young and inexperienced workers. An inverse relationship was seen between age and prevalence of occupational allergic dermatitis. Allergic hand dermatitis was the commonest presentation in occupational allergic dermatitis. This was followed by dermatitis of the exposed skin (face, neck, hands and forearms). The common sensitising agents identified were rubber chemicals and nickel. The two main groups at risk were factory workers and medical personnel. The common allergens found in factory workers were epoxy resin, pewter, nickel and rubber chemicals. Exposure dermatitis occurred in patients working in the pewter industry. Two thirds of medical personnel with hand dermatitis were allergic to rubber gloves. One year follow up after patch testing showed that 19% of patients still suffered from chronic dermatitis. Dermatitis improved in 34% of patients. Forty-seven percent were cured and stopped attending the clinic after patch testing and adequate counselling.

Neurotoxic effects of n-hexane on the human central nervous system: evoked potential abnormalities in n-hexane polyneuropathy.

Chang, Y C

1987-01-01

An outbreak of n-hexane polyneuropathy as a result of industrial exposure occurred in printing factories in Taipei area from December 1983 to February 1985. Multimodality evoked potentials study was performed on 22 of the polyneuropathy cases, five of the subclinical cases, and seven of the unaffected workers. The absolute and interpeak latencies of patterned visual evoked potential (pVEP) in both the polyneuropathy and subclinical groups were longer than in the normal controls. The pVEP interpeak amplitude was also decreased in the polyneuropathy cases. Brainstem auditory evoked potentials (BAEP), showed no difference of wave I latency between factory workers and normal controls, but prolongation of the wave I-V interpeak latencies was noted, corresponding with the severity of the polyneuropathy. In somatosensory evoked potentials (SEPs), both the absolute latencies and central conduction time (CCT) were longer in subclinical and polyneuropathy cases than in the unaffected workers and normal controls. From this evoked potentials study, chronic toxic effects of n-hexane on the central nervous system were shown. PMID:3031221

The nonsteroidal anti-inflammatory drug carprofen was used in humans in the 1980s, before its withdrawal due to adverse effects. It re-emerged for veterinary uses, for which it is still widely prescribed, in the 1990s. There has been one previous report published of photoallergic contact dermatitis (PACD) in a pharmaceutical factory worker exposed to carprofen. Investigation of carprofen as a cause of PACD in pharmaceutical factory workers presenting with facial dermatitis. Photopatch testing to carprofen dilutions in two pharmaceutical factory workers and three healthy volunteer controls using the European consensus methodology. This was followed by testing of eight further employees, referred by occupational health services, in the same factory. The index patient suspected a problem with carprofen and was found to have PACD to carprofen. The second patient presented with a widespread, although especially photoexposed site, dermatitis and was initially labelled as having an 'unclassified dermatitis'. Only subsequently was her exposure (indirect; she did not work in the packaging section of the factory like the first patient) to carprofen recognized and testing confirmed both contact allergy and PACD to carprofen. One of three healthy volunteer controls had an active photoallergy sensitization event to carprofen starting 10 days after photopatch testing. Three of eight factory employees subsequently referred because of skin problems had carprofen PACD. Carprofen is a potent photoallergen. These cases emphasize the importance of photopatch testing, and considering agents not included in standard series, when investigating patients presenting with a photoexposed site dermatitis.

An industrial process such as wheat processing generates significant noise which can cause adverse effects on workers and the general public. This study assessed the noise level at a wheat processing mill in Ilorin, Nigeria. A portable digital sound level meter HD600 manufactured by Extech Inc., USA was used to determine the noise level around various machines, sections and offices in the factory at pre-determined distances. Subjective assessment was also mode using a World Health Organization (WHO) standard questionnaire to obtain information regarding noise ratings, effect of noise on personnel and noise preventive measures. The result of the study shows that the highest noise of 99.4 dBA was recorded at a pressure blower when compared to other machines. WHO Class-4 hearing protector is recommended for workers on the shop floor and room acoustics should be upgraded to absorb some sounds transmitted to offices.

This study aims to quantify dust exposure among the workers in four different industrial settings: rice mills, flour mills, oil mills, and tea factories and to compare the obtained data with the permissible exposure limit (PEL) of Indian Union Ministry of Labour as well as to compare the dust exposure across activities and seasons. RespiCon(TM) particle sampler was used for collecting dust concentration in the breathing zone of the workers. In total, 149 workers participated in the study and 204 samples were collected. Samples were collected in the vicinity of different processing operations. Samples in the rice mills were collected for two consecutive years in two seasons; however samples from other industries were collected for 1 year. The results indicate that geometric mean (GM) of dust exposure was significantly (P < 0.0001) different among industrial settings. Respirable dust were 8.22, 5.76, 2.98, and 6.34mg m(-3) and total dust exposure were 81.05, 111.02, 56.68, and 39.85mg m(-3) in the rice mills, oil mills, flour mills, and tea factories, respectively. Considerable variations in dust exposure were observed in different activities in the rice and oil mills; however variation was relatively less in the flour mills and tea factories. In the rice mills, dust concentration was higher in winter than those obtained in autumn and it is significantly different (P < 0.05) for inhalable dust and total dust. Positive correlation was obtained in thoracic dust (r (2) = 0.94) and inhalable dust (r (2) = 0.97) with total dust and thoracic dust with inhalable dust (r (2) = 0.89). The results show that majority of the workers are exposed to higher level of respirable dust as compared to the PEL, while total dust exposure to all the workers were higher than the PEL; thus, immediate reduction of dust exposure among the workers is necessary for preventing respiratory system impairment. © The Author 2015.

Various work-related issues including mental health have been described for the electronic industry. Although East Asian countries play important roles in the electronics industry, the association between job demands and emotional symptoms has been rarely examined. The present study recruited 603 workers from either office or clean room environments in an electronics factory in Taiwan. Their personal factors, work-related factors, and emotional symptoms were assessed by a self-administered questionnaire. The symptoms of depression and hostility were reported in 24.88% and 24.38% of the subjects, respectively, while 14.93% reported both. A multivariate analysis showed that, overall, women workers were more likely to have emotional symptoms than male workers (odds ration (OR) = 1.50, 95% CI = 1.02-2.18). Among clean room workers, working under high pressure (OR = 1.84, 95% CI = 1.05-3.21), conflicting demands (OR = 2.15, 95% CI = 1.30-3.57), and social isolation at work (OR = 2.99, 95% CI = 1.23-7.30) were associated with emotional symptoms. The findings suggest that in the Asian electronics industry, for women, working under high pressure, conflicting demands, and social isolation at work are risk factors for emotional symptoms, especially for clean room workers. Further large-scale, longitudinal studies are necessary to confirm and prevent the mental health problems in this fast-evolving, highly competitive industry.

This study investigated the correlation between knowledge, attitude and practices on HIV and AIDS in the context of Nepal.The study was conducted among the 404 respondents; selected from the transport workers, garment factory workers, brick factory workers and health workers. It was non-experimental cross sectional study based on descriptive as well as correlational research design. Simple random technique was used to select the respondents. Survey was conducted to collect the primary data and r value was used to analyze the correlation between variables. Finding shows that 391 (96.8%) respondents have heard about HIV and AIDS; among them 388 (95.8%) respondents were mentioned that they had knowledge of way of HIV transmission also. Total 50 out of 171 unmarried (29.2%) respondents had pre-marital sexual experience. It was found that only 71 (25.6%) respondents had used the condom during their first time sexual intercourse.There was significant association (p=.000) found between the knowledge on way of HIV transmission and occupation of respondents, similarly relationship found (r = .815, p = .000 (2-tailed) between marriage age and age of first time sexual intercourseof respondents. But there was no relationship (r = .097 and p =.106 (2-tailed) found between Knowledge on way of HIV transmission and sex with non-regular sex partners. Data showed that safer sex practices was low than the level of knowledge. The educational status of respondents shows the positive association with attitude towards the necessary to have knowledge of HIV and AIDS.

The purpose of this study has been to assess ambient bisphenol A (BPA) levels in workplaces and urine levels of workers and to establish a BPA database for different populations in Malaysia. Urine samples were collected from plastic factory workers and from control subjects after their shift. Air samples were collected using gas analyzers from 5 sampling positions in the injection molding unit work area and from ambient air. The level of BPA in airborne and urine samples was quantified by the gas chromatography mass spectrometry - selected ion monitoring (GCMS-SIM) analysis. Bisphenol A was detected in the median range of 8-28.3 ng/m³ and 2.4-3.59 ng/m³ for the 5 sampling points in the plastic molding factory and in the ambient air respectively. The median urinary BPA concentration was significantly higher in the workers (3.81 ng/ml) than in control subjects (0.73 ng/ml). The urinary BPA concentration was significantly associated with airborne BPA levels (ρ = 0.55, p < 0.01). Our findings provide the first evidence that workers in a molding factory in Malaysia are occupationally exposed to BPA. Int J Occup Med Environ Health 2017;30(5):743-750.

In this study, cardiometabolic risk associated with betel-quid, alcohol and cigarette use, based on a simple index-lipid accumulation product (LAP), was investigated in Taiwanese male factory workers. Male factory workers were recruited during their annual routine health examination at a hospital in south Taiwan. The risk of cardiometabolic disorders was estimated by the use of LAP, calculated as (waist circumference [cm]-65)×(triglyceride concentration [mmol/l]). Multiple linear regression analyses were conducted to assess the risk factors of natural logarithm-transformed LAP. Of the 815 participants, 40% (325/815) were current alcohol users, 30% (248/815) were current smokers and 7% (53/815) were current betel-quid users. Current betel-quid use, alcohol use, older age, lack of exercise and higher body mass index were found to be significant and independent factors associated with natural logarithm-transformed LAP. Betel-quid and alcohol, but not cigarette use, were independent risk factors of logarithm-transformed LAP, adjusting for age, exercise and body mass index in male Taiwanese factory workers. LAP can be considered as a simple and useful method for screening of cardiometabolic risk. © The Author 2014.

Pulmonary function and symptoms in workers exposed to wood dust.

PubMed Central

Shamssain, M H

1992-01-01

BACKGROUND: Exposure to wood dust can cause a variety of lung problems, including chronic airflow obstruction. METHODS: Forced vital capacity (FVC), forced expiratory volume in one second (FEV1), forced expiratory ratio (FEV1/FVC x 100), forced expiratory flow (FEF), forced mid expiratory flow (FMF), peak expiratory flow (PEF), and respiratory symptoms (cough, phlegm, breathlessness, wheezing, and nasal symptoms) were recorded in 145 non-smoking workers (77 male, 68 female) exposed to wood dust in a furniture factory in Umtata, Republic of Transkei, and 152 non-smoking control subjects (77 male, 75 female) from a bottling factory with a clean environment. RESULTS: After adjustment for age and standing height the forced expiratory indices were significantly lower in the exposed male workers than in the control subjects. FEF and PEF in the exposed men were 81.3% and 89.4% of predicted values and were lower than other indices. FVC in exposed men showed a significant inverse correlation with exposure (expressed in number of years of employment). The FVC was reduced by 26 ml per year of employment. The proportion of men with an FEV1/FVC below 70 was higher in exposed workers than in control subjects and higher in the exposed workers with more years of employment. The exposed workers had more respiratory symptoms than the control subjects, the prevalence, especially of cough and nasal symptoms, increasing with the increase in the number of years of employment. CONCLUSION: Workers exposed to pine and fibre dust have more respiratory symptoms and a greater risk of airflow obstruction. PMID:1549828

Cullen, M R; Checkoway, H; Alexander, B H

1996-11-01

Four cases of pituitary adenoma among employees at a primary aluminum production factory were identified over a five year period by a community physician. The objective of this investigation was to determine whether there has been a comparable high incidence in other aluminum factories, and if particular jobs, departments, or activities in the industry are associated with higher rates of the disease. Pituitary adenoma in employees at all United States factories of the company for the years 1989-94 was assessed by a search of a health data information bank and an insurance data base covering present and past employees of the corporation. The incidence in the aluminum workers was estimated and compared with the workers in the index plant. A nested case control study was conducted to compare employment histories of identified cases with those of age and sex matched controls selected from the health information data base. 25 cases, including the index cases, were identified which had been diagnosed during the period 1989-94. The resulting rate of 10.4/100,000 person-years was much lower than that at the index plant. Case-control analysis showed no coherent pattern of location, department, or job significantly associated with risk. In particular, jobs and departments associated with exposures common to aluminum smelting-such as coal tar pitch volatiles and fluorides-were shown to be uncommon among cases compared with age and sex matched controls. Overall, despite the unprecedented cluster at a single plant, no strong evidence was found that the rate of pituitary adenoma is increased in aluminum workers generally. We found no association with any work activity or location in the industry to suggest a work related or exposure related cause for the disease.

The development of occupational health services in Norway is explored by making a case study of both a chocolate factory and a cement factory. The study shows how different motives and ideological positions promoted the industrial health service. Prominent among them were a social and political philosophy, those of welfare capitalism, as an alternative to socialism and state policy in building the affluent society and the move toward improvements of production. All leading to a growing interest in the human factor in industry, where the medical officer should help to shape a satisfied, rational and productive worker in a healthy work environment.

The MRI technique has been used in diagnosis of manganism in humans and non-human primates. This cross-sectional study was designed to explore whether the pallidal signal intensity in T1-weighted MRI correlated with Mn levels in the blood compartment among Mn-exposed workers and to understand to what extent the MRI signal could reflect Mn exposure. A group of 18 randomly selected male Mn-exposed workers of which 13 were smelting workers with high exposure (mean of airborne Mn in work place: 1.26 mg/m3; range: 0.31–2.93 mg/m3), and 5 power distribution control workers with low exposure (0.66 mg/m3 and 0.23–0.77 mg/m3) from a ferroalloy factory, and another group of 9 male subjects as controls from a non-smelting factory who were office or cafeteria workers (0.01 mg/m3 and 0–0.03 mg/m3) were recruited for neurological tests, MRI examination, and analysis of Mn in whole blood (MnB), plasma (MnP) or red blood cells (MnRBC). No clinical symptoms and signs of manganism were observed among these workers. MRI data showed average increases of 7.4% (p < 0.05) and 16.1% (p < 0.01) in pallidal index (PI) among low- and high-exposed workers, respectively, as compared to controls. Fourteen out of 18 Mn-exposed workers (78%) had intensified PI values, while this proportion was even higher (85%) among the high Mn-exposed workers. Among exposed workers, the PI values were significantly associated with MnRBC (r = 0.55, p = 0.02). Our data suggest that the workers exposed to airborne Mn, but without clinical symptoms, display an exposure-related, intensified MRI signal. The MRI, as well as MnRBC, may be useful in early diagnosis of Mn exposure. PMID:16978697

This cross-sectional study was designed to explore whether the pallidal signal intensity in T1-weighted MRI correlated with Mn levels in the blood compartment among Mn-exposed workers and to understand to what extent the MRI signal could reflect Mn exposure. A group of 18 randomly selected male Mn-exposed workers of which 13 were smelting workers with high exposure (mean of airborne Mn in work place: 1.26 mg/m3; range: 0.31-2.93 mg/m3), and 5 power distribution control workers with low exposure (0.66 mg/m3 and 0.23-0.77 mg/m3) from a ferroalloy factory, and another group of 9 male subjects as controls from a non-smelting factory who were office or cafeteria workers (0.01 mg/m3 and 0-0.03 mg/m3) were recruited for neurological tests, MRI examination, and analysis of Mn in whole blood (MnB), plasma (MnP) or red blood cells (MnRBC). No clinical symptoms and signs of manganism were observed among these workers. MRI data showed average increases of 7.4% (p<0.05) and 16.1% (p<0.01) in pallidal index (PI) among low- and high-exposed workers, respectively, as compared to controls. Fourteen out of 18 Mn-exposed workers (78%) had intensified PI values, while this proportion was even higher (85%) among the high Mn-exposed workers. Among exposed workers, the PI values were significantly associated with MnRBC (r=0.55, p=0.02). Our data suggest that the workers exposed to airborne Mn, but without clinical symptoms, display an exposure-related, intensified MRI signal. The MRI, as well as MnRBC, may be useful in early diagnosis of Mn exposure.

Econophysics of a ranked demand and supply resource allocation problem

We present a two sided resource allocation problem, between demands and supplies, where both parties are ranked. For example, in Big Data problems where a set of different computational tasks is divided between a set of computers each with its own resources, or between employees and employers where both parties are ranked, the employees by their fitness and the employers by their package benefits. The allocation process can be viewed as a repeated game where in each iteration the strategy is decided by a meta-rule, based on the ranks of both parties and the results of the previous games. We show the existence of a phase transition between an absorbing state, where all demands are satisfied, and an active one where part of the demands are always left unsatisfied. The phase transition is governed by the ratio between supplies and demand. In a job allocation problem we find positive correlation between the rank of the workers and the rank of the factories; higher rank workers are usually allocated to higher ranked factories. These all suggest global emergent properties stemming from local variables. To demonstrate the global versus local relations, we introduce a local inertial force that increases the rank of employees in proportion to their persistence time in the same factory. We show that such a local force induces non trivial global effects, mostly to benefit the lower ranked employees.

Glues are strong, liquid adhesive derived from animal tissues. It has been shown that glue sniffing is associated with demyelinating polyneuropathy. The low molecular weight agents which cause occupational lung disease have generally included the isocyanates exposure to which could result in asthma among workers. Toluene is also used widely in glue and adhesive industry and households where toluene exposure and abuse can occur. To study some respiratory and neurological disorders that may arise in workers in a bone glue factory in Queisna industrial zone, Menoufyia governorate, Egypt. In a historical cohort study, the exposed participants (n = 50) were recruited from workers in a bone glue factory in Queisna industrial zone, Menoufyia governorate. The unexposed group was selected from workers' relatives who had never worked in glue industry. All participants completed a pre-designed questionnaire on personal and occupational histories. Pulmonary function tests as well as electromyography (EMG) were performed for all participants. Urinary hippuric acid was also measure in all participants. The prevalence of cough, asthmatic attacks and paresthesia were significantly higher among exposed than unexposed participants. Abnormal spirometric measurements (particularly towards obstruction), abnormal EMG and positive urinary hippuric acid were significantly more prevalent among exposed than unexposed group. Spirometry and EMG should be included in the periodic medical examination for exposed workers for early detection of respiratory and neurological disorders. Urinary hippuric acid could be a useful indicator of the nerve conduction abnormalities and should be measured periodically for these workers.

Objective. This paper aimed to determine the standardised incidence ratio (SIR) of malignant pleural mesothelioma (MPM) in workers exposed to asbestos in Taiwan. Methods. All workers employed in asbestos-related factories and registered by the Bureau of Labour Insurance between 1 March, 1950, and 31 December, 1989, were included in the study and were followed from 1 January, 1980, through 31 December, 2009. Incident cases of all cancers, including MPM (ICD-9 code: 163), were obtained from the Taiwan Cancer Registry. SIRs were calculated based on comparison with the incidence rate of the general population of Taiwan and adjusted for age, calendar period, sex, and duration of employment. Results. The highest SIR of MPM was found for male workers first employed before 1979, with a time since first employment more than 30 years (SIR 4.52, 95% CI: 2.25–8.09). After consideration of duration of employment, the SIR for male MPM was 5.78 (95% CI: 1.19–16.89) for the workers employed for more than 20 years in asbestos-related factories. Conclusions. This study corroborates the association between occupational asbestos exposure and MPM. The highest risk of MPM was found among male asbestos workers employed before 1979 and working for more than 20 years in asbestos-related factories. PMID:26290869

The general and cancer mortalities of rubber workers at a large tyre factory were studied in an area of marked regional variation in death rates. Three quinquennial intakes of male rubber workers engaged between January 1946 and December 1960 formed a composite cohort of 6454 men to be followed up. Over 99% were successfully traced by December 1985. The cohort analysis used both national and local rates as reference statistics for several causes. Between 1951 and 1985, a national standardized mortality ratio (SMRN) of 101 for all causes (based on 2556 deaths) was noted, whereas the local standardized mortality ratio (SMRL) was only 79. For all cancers, the figures were 115 (SMRN) and 93 (SMRL), for stomach cancer they were 137 (SMRN) and 84 (SMRL), and for lung cancer they were 121 (SMRN) and 94 (SMRL). No outright excesses against the national norm were observed for other cancers except for larynx, brain and central nervous system and thyroid cancer and the leukaemias. Excesses were statistically significant for cancer of the gallbladder and the bile ducts, for silicotuberculosis (SMRN = 1000) and for the pneumoconioses (SMRN = 706). Deaths from cerebrovascular diseases, chronic bronchitis and emphysema showed statistically significant deficits using either norm. These results from a large factory cohort study of rubber workers, followed for over three decades, demonstrate the marked discrepancy that can result from using only one reference statistic in areas of significant variation in mortality patterns.

Crespi d'Adda is a late 19th century company town established around a textile factory by Cristoforo Benigno Crespi and his son Silvio. It was an ideal model of company residency being a self-sufficient microcosm equipped with all the services needed by a community where the life of workers and their families was revolving around the factory and the working requirements. It was the expression of philanthropic and patronizing enlightened entrepreneurs at that time, committed in protecting workers' life inside and outside the factory, resulting into a more affectionate and productive manpower. Silvio Benigno Crespi developed an extensive activity to improve working conditions, with special reference to accident prevention and work-related diseases, as well as night work in factories, weekly day off, reduction of working hours: we can say that in some ways he was concerned also with psychosocial risks.

This study aimed to explore the association between shift work and work-related injuries. We collected data on workers from an electronics factory. This cross-sectional study included 13,610 subjects, who were assessed based on a self-reported questionnaire about their shift work experiences, work-related injuries, and other covariates. Multiple logistic regression models were used to evaluate the associations between shift work and work-related injuries and were estimated using the odds ratio. We found that the current and past shift workers, compared to non-shift workers, were associated with a 2.7- and 1.7-fold higher risk of work-related injury. There was a dose-response relationship between shift work duration and work-related injury among current female shift workers. Shift work increased the risk of work-related injuries, and the impact could be different depending on gender.

North American workers usually stand while working, and prolonged standing is associated with discomfort and cardiovascular problems. Moving may alleviate the problems, but optimum mobility is unknown. The effects of variations in mobility were explored among (1) 34 health care workers whose symptoms of orthostatic intolerance (OI) were recorded after work; (2) 45 factory and laundry workers. Postures were observed over a workday and blood pressure (BP) and heart rate (HR) of both groups were recorded before and after work. Among health care workers, 65% manifested OI symptoms. In a multiple logistic regression, presence of >or= 1 symptom of OI was associated with static postures and being female (p=0.001). More static standing was associated with a larger drop in BP (p=0.04) in both populations. The results suggest that more static standing postures are associated with OI and musculoskeletal symptoms and with a subclinical drop in BP.

Trichloroethylene (TCE) is an important volatile organic compound once widely used in industry throughout the world. Occupational exposure to TCE can cause a number of health hazards such as allergic reactions and genetic damage. The purpose of this study was to evaluate occupational exposure to TCE, by analysis of the air in the breathing zone and of urine from workers employed in a clock manufacturing factory. A subjective symptom survey was conducted by using a self-administered questionnaire to evaluate the health hazards. Micronucleus (MN) frequency, based on the cytokinesis-block micronucleus assay (CBMN) in peripheral blood lymphocytes, (PBLs) was used as a biomarker for chromosome damage. A total of 244 participants, including 171 workers occupationally exposed to TCE and 73 non-exposed control employees, working mainly in office jobs in the same factory, were enrolled in this study. Analyses of airborne TCE concentrations in the workplace, and of urinary trichloroacetic acid (TCA) of the workers and controls, were performed by Gas Chromatography-Electron Capture Detector (GC-ECD) using the modified headspace technique. The average concentration of TCE in the workplace breathing zone was 27.83 ± 6.02 ppm. The average level of urinary TCA of the exposed workers and controls was 14.84 ± 1.62, 2.95 ± 0.28 mg/L. The frequency of MN/1000BN was 7.029 ± 0.39, significantly higher than for those in the control group (3.57 ± 0.31, p = 0.001). According to multiple linear regression analysis, the results indicated that urinary TCA levels correlated with the increased MN in exposed workers (r = 0.285, p < 0.001). The prevalence rate of subjective symptoms in the exposed group was 9.61-11.76 times higher than the rate of the non-exposed group (p < 0.001). It was found that skin (29.6%) and respiratory symptoms (21.1%) were the most frequent among the exposed workers. In conclusion, these results indicate that increased micronucleus frequency is associated with occupational trichloroethylene exposure. The use of TCE in the factory is threatening workers' health.

Of 22 workers in a ski factory, occupational allergic contact dermatitis was found in 8. 6 were sensitive to epoxy resin compounds, i.e., epoxy resins, hardeners or diluents, 1 to cobalt in glass-fiber reinforcements, and 1 to formaldehyde in a urea-formaldehyde glue and a lacquer. 4 workers had irritant contact dermatitis from epoxy resin compounds, lacquers, sanding dust, or glass-fiber dust. 3 had contact allergy from a new sensitizer, diethyleneglycol diglycidyl ether, in a reactive diluent. Immediate transfer of workers sensitized to epoxy resin from epoxy exposure prevents aggravation of their dermatitis and broadening of the sensitization to epoxy hardeners, diluents and other compounds.

Male migrant workers display high risk sexual behavior and have been shown to have higher prevalence of sexually transmitted infections (STIs), which make them more vulnerable to HIV infection. We aimed to estimate the prevalence of self-reported STIs and delineate their determinants among male migrant factory workers in Faridabad, Haryana. Male workers in two selected factories, who were aged ≥18 years, were born outside Haryana (destination), and who had migrated to Haryana after the age of 15 years were eligible. Socio-demographic information, HIV/AIDS knowledge and behavior, and self-reported STI symptoms in the last 1 year were ascertained by face-to-face interview. Determinants of STIs were identified by regression analysis. Totally 755 eligible workers participated. Mean ± SD age was 31.4 ± 8.2 years and migration duration was 9.5 ± 6.7 years. At least one STI symptom was reported by 41.7% of the participants (burning micturition- 35%, inguinal bubos-5.2%, genital ulcers- 2.6%, urethral pus discharge- 1.3%). Factors associated with STIs were higher age at migration, lower HIV/AIDS knowledge, paid sex in the last year, non-use of condoms during the last non-spousal sex, and unfavorable intention to use condom. Prevalence of self-reported STIs among these migrant men was high. Targeted Interventions among migrant workers need to be strengthened for control and prevention of STIs.

Hazarding health: experiences of body, work, and risk among factory women in Malaysia.

In the 1970s, Malaysia launched an export-oriented development strategy as a means of financing the nation's modernization. The success of the strategy hinged significantly on intensive recruitment of women for factory employment. I draw on descriptive qualitative research, including interviews (51), surveys (106), and ethnography in Malaysia to investigate factory women's experiences of work and work-related health risks. Discourse analysis surfaced a latent consciousness of bodily changes in relation to work. A grounded theory analysis showed a compromised access to occupational risk knowledge that may bear negatively on women's well-being and the role women's new labor identities played in mediating the meanings of work and risks. Given the predominance of women workers in low-end manufacturing globally, I aimed to contribute to theoretical and applied understandings of gender, globalization, and health.

To study the range of urinary levels of 4,4'-methylenedianiline (MDA), a metabolite of methylenediphenyl diisocyanate (MDI), across factories in the polyurethane industries and to evaluate the validity of this biomarker to assess MDI occupational exposure. Workers exposed to MDI, as well as non-occupationally exposed subjects, were studied and pre- and post-shift urine samples were collected from 169 workers of 19 French factories and 120 controls. Details on work activities and practices were collected by a questionnaire and workers were classified into three job categories. The identification and quantification of the total urinary MDA were performed by high-performance liquid chromatography with electrochemical detection (HPLC/EC). For all the factories, MDA was detectable in 73% of the post-shift urine samples. These post-shift values, in the range of <0.10 (detection limit)-23.60 microg/l, were significantly higher than those of the pre-shift samples. Urinary MDA levels in the control group were in the range of < 0.10-0.80 microg/l. The degree of automation of the mixing operation (polyols and MDI) appears as a determinant in the extent of exposure levels. The highest amounts of MDA in urine were found in the spraying or hot processes. The excretion levels of the workers directly exposed to the hardener containing the MDI monomer were significantly higher than those of the other workers. In addition, skin exposure to MDI monomer or to polyurethane resin during the curing step were always associated with significant MDA levels in urine. Total MDA in post-shift urine samples is a reliable biomarker to assess occupational exposure to MDI in various industrial applications and to help factories to improve their manufacturing processes and working practices. A biological guiding value not exceeding 7 microg/l (5 microg/g creatinine) could be proposed in France.

The purpose of this study is to assess whether occupational exposure to substances used in the cosmetic factories may cause effects on the liver and blood counts in exposed workers. The study included 48 exposed workers and 86 unexposed controls. All workers included in the study underwent blood count, white blood count, total, direct and indirect bilirubin, transaminases, alkaline phosphatase and cholinesterase. The differences between the means and frequencies were compared using the Student's t-test and chi-square test with Yates correction and were considered significant when the p value was <0.05. The analysis of the results shows that 35.4% of workers in the cosmetics industry had liver test values above the range. We noted a statistically significant higher prevalence of GPT (p <0.05) and total bilirubin (p <0.05) in the workers of the cosmetics industry compared with the control group. The results obtained suggest that occupational exposure to low doses of substances used in the cosmetic industry is able to influence some liver parameters in occupationally exposed workers.

Six volunteers (two office and four cadmium (Cd)-exposed workers, all nonsmokers) from an electric condenser factory participated in a study involving the measurement of cadmium in air and in dust, the evaluation of hand and mouth contamination by cadmium, and the determination of fecal cadmium. The mean levels of total airborne cadmium measured with static and personal samplers were for the exposed workers 9.5 and 16.7 microgram/m3, respectively, and for the office workers 0.3 and 0.5 microgram/m3, respectively. In the office workers, hand contamination by Cd hardly changes over the workday (less than 10 microgram/hand), whereas in the exposed workers important hand contamination by Cd was observed (up to 1,200 microgram/hand during the workday and up to 300 microgram/hand before lunch or before leaving the factory). Mouth contamination by Cd is rather similar in both groups on Monday morning, but increases 20- to 50-fold on Friday afternoon in the Cd workers against a slight increase for the office workers. The concentration of Cd in the feces was not much different between Sunday and Friday in the office workers, whereas in the exposed workers it was higher on Friday than on Sunday. There is suggestive evidence from a comparative study of fecal cadmium in two Cd-exposed volunteers who carried out their jobs with and without gloves that direct cadmium intake from hand contamination may contribute to the overall Cd absorption. A limited study in a glassware factory (As2O3 exposure) involving the measurement of total airborne arsenic, the determination of urinary arsenic, and the evaluation of hand and mouth contamination by arsenic before and after the workshift suggests that the high urinary arsenic levels (300 microgram/g creatinine) are likely to be more related to an increased oral intake from contaminated hands than to an increased absorption from the lungs.

The effect of chronic cyanide exposure in the electroplating sections of three factories employing 36 workers was studied and compared with a control group. The concentration of cyanides to which the workers were exposed was measured. The regression line showing the relationship between thiocyanates in urine and the concentration of cyanides in the air was plotted. Increased percentages of haemoglobin and lymphocyte count were present in all exposed workers, in addition to punctate basophilia in 28 workers. Cyanmethaemoglobin was found to be characteristic. Apart from other complaints, two men with psychosis similar to one case reported in therapeutic thiocyanate intoxication were found. Twenty of the workers had thyroid enlargements to a variable degree and consistency, in two of whom it resembled lymphadenoid goitre. Thyroid 131I uptakes at 4 and 24 hours were significantly higher than in the controls, while 131PBI was unchanged. The reason for this iodine deficiency-like action is discussed. PMID:1156569

Several substances used in rubber processing are known to be genotoxic. Workers in a rubber tyre factory, exposed to a broad spectrum of contaminants such as benzo[a]pyrene, benzo-fluoranthene, naphthalene, acetonaphthene, alkenes and 1,3-butadiene have been regularly examined for several years: chromosomal aberrations in lymphocytes, mutagenicity of urine (by use of the Ames test) and various parameters of blood and urine were assessed. An elevated level of mercapturic acid derivatives was found in the urine of employees, which is indicative of environmental exposure to toxicants with alkylating activity. We have now extended this study by examining genotoxicity with the modified Comet assay in parallel with chromosomal aberrations and micronucleus formation as well as immunological endpoints. Twenty-nine exposed workers from this factory were compared with 22 non-exposed administrative staff working in the same factory, as well as with 22 laboratory workers. The absolute numbers of peripheral leukocytes were significantly higher in the exposed group than in either of the control groups (p < 0.001). The erythrocyte mean cell volume was significantly higher in exposed workers in comparison with laboratory controls (p < 0.05). Percentages of lymphocytes, polymorphonuclear leukocytes, monocytes and eosinophils were not altered. The proliferative response of T- and B-cells to mitogen treatment when calculated per number of lymphocytes and adjusted for smoking, age and years of exposure did not differ between exposed and control groups. Endogenous strand breaks (including alkali-labile sites) and altered bases (formamidopyrimidine glycosylase- and endonuclease III-sensitive sites) were measured by the Comet assay in lymphocyte DNA. Exposed workers had significantly elevated levels of DNA breaks compared with office workers (p < 0.00001) or with laboratory controls (p < 0.00001). Micronuclei occurred at significantly higher frequencies in the exposed group than in controls (p < 0.00001), though the frequencies were all within the normal range. Significant correlations were seen between individual values of strand breaks, micronuclei and chromatid/chromosome breaks and certain immunological parameters.

The frequency of MN/1000BN was 7.029 ± 0.39, significantly higher than for those in the control group (3.57 ± 0.31, p = 0.001). According to multiple linear regression analysis, the results indicated that urinary TCA levels correlated with the increased MN in exposed workers (r = 0.285, p < 0.001). The prevalence rate of subjective symptoms in the exposed group was 9.61-11.76 times higher than the rate of the non-exposed group (p < 0.001). It was found that skin (29.6%) and respiratory symptoms (21.1%) were the most frequent among the exposed workers. In conclusion, these results indicate that increased micronucleus frequency is associated with occupational trichloroethylene exposure. The use of TCE in the factory is threatening workers’ health.

Processing of coir, which is the fibre obtained from the husk of the coconut, is a dusty procedure; 779 workers in two coir processing factories in Sri Lanka were examined clincally and radiographically for evidence of respiratory disease. Respiratory symptoms were present in 20 (2-6%) of them, which is no higher than in the general population. Respiratory disease such as asthma, chronic bronchitis, byssinosis, and pulmonary tuberculosis which may occur from occupational exposures were considered, but there was no evidence to suggest a definite association between these conditions and coir dust. Twenty-two workers had abnormal chest radiographs, but when compared with a control group of 591 workers from an engineering firm where lesions were found in 20 cases, there was no significant difference. In the opinion of the medical officer, management and workers of the large factory investigated, coir dust does not produce any respiratory disability. The chemical composition of coir dust is similar to that of sisal which is also relatively inert.

The purpose of this research was to study factors affecting musculoskeletal disorders. The sample population of the study was 528 factory workers from the frozen food industry, as well as a controlled group of 255 office workers. The samples were collected during interviews using the Nordic questionnaire to assess musculoskeletal disorders, and to assess the risk by the rapid upper limb assessment and rapid entire body assessment techniques. The findings of the study were that most symptoms were found in the dissecting department, higher than in the controlled group. The details of the symptoms were, accordingly: elbow pain (adjusted odds ratio, 35.1; 95% CI [17.4, 70.9]). Regarding the risk of alcohol drinking, workers were exposed to more risks when alcohol was consumed. It is suggested that workers' health should be monitored regularly. People who work in a cold environment should be encouraged to wear body protection and to avoid drinking.

Twenty-two workers had abnormal chest radiographs, but when compared with a control group of 591 workers from an engineering firm where lesions were found in 20 cases, there was no significant difference. In the opinion of the medical officer, management and workers of the large factory investigated, coir dust does not produce any respiratory disability. The chemical composition of coir dust is similar to that of sisal which is also relatively inert. PMID:1125129

Certain occupations are reported to be associated with a high risk for carpal tunnel syndrome (CTS). In this study, we investigated the development of CTS in iron-steel industry workers. Subjects were recruited from a factory of 650 workers and assessed by means of history, physical examination and electrophysiological testing. Seventy-nine subjects from the factory and 53 healthy controls with occupations unrelated to heavy physical work were assessed. None of the worker group had electrophysiological evidence of CTS. One subject in the control group has electrophysiological evidence of CTS. In the worker group, all sensory nerve conduction velocities and ulnar nerve action potential amplitudes in both hands and distal motor latencies were statistically different. In our study, among a group of heavy labourers, no cases of CTS were detected. However, all electrophysiologic parameters of workers were different from controls. Our results point to a diffuse, but subclinical injury of peripheral nerves under heavy physical work conditions, instead of a local effect such as CTS.

Objectives: Latex product manufacturing is an important industry in south-east Asia but has the potential for considerable occupational exposure of workers to latex allergens. Although exposure to latex allergens can result in adverse health reactions, few studies to characterize this exposure have been conducted to date. This study therefore aimed to characterize current airborne inhalable dust and the specific allergen, Hev b 6.02, exposures in this industry in Thailand. Methods: Workers were recruited from three factories in the southern part of Thailand. Full-shift inhalable dust personal air sampling was conducted using IOM sampling heads equipped with polytetrafluoroethylene filters at a 2.0 l min−1 flowrate. After weighing to determine inhalable dust levels, filters were extracted and analysed for Hev b 6.02 using an enzyme immunometric assay. Results: Two hundred and seventy-five workers agreed to participate, resulting in a total of 292 measurements. Geometric mean (GM) personal exposure to inhalable dust was 0.88mg m–3, but individual exposures up to 12.34mg m–3 were measured. The pattern of exposure was similar across factories, with highest exposures in the stripping (GM 2.08–4.05mg m–3 for the 3 factories) and tumbling departments (1.11–2.17mg m–3). Within-worker (day-to-day) variability contributed 92% to total variability. The Hev b 6.02 exposure pattern was similar with time-weighted average GM exposure levels in the oldest factory ranging from 8.7mg m–3 in the laboratory to 30.2mg m–3 in the stripping department. In contrast to inhalable dust exposure, total exposure variability was primary driven by variability between workers (67%). Conclusions: Workers in these latex product factories get routinely exposed to measurable Hev b 6.02 levels, which may give rise to increased incidence of allergic symptoms and occupational asthma. Also, in this measurement campaign a 10mg m–3, but not 15mg m–3, occupational exposure limit for inhalable dust was occasionally exceeded. Highest Hev b 6.02 exposures were found in the stripping and tumbling departments, which would be natural targets for interventions aimed at reducing exposure. PMID:24569810

Personal exposures to ammonia and acute respiratory effects were determined in workers at a urea fertilizer factory in Bangladesh. Full-shift personal exposure to ammonia was measured using a PAC III direct reading instrument and Drager diffusion tubes. Respiratory symptoms were elicited by a questionnaire study (n = 113), and preshift and postshift lung function (FVC, FEV1, and PEFR) were tested using spirometry (n = 88). Urea plant workers had higher mean exposure to ammonia and prevalence of acute respiratory symptoms than did workers in the ammonia plant. The symptoms with highest prevalence in the urea plant were chest tightness (33%) and cough (28%). FVC and FEV1 decreased significantly across the work shift among urea plant workers. The higher level of exposure to ammonia in the urea plant was associated with an increased prevalence of respiratory symptoms and an acute decline in lung function.

Sweat or no sweat: foreign workers in the garment industry in Malaysia.

PubMed

Crinis, Vicki

2010-01-01

In the last decade factory owners, in response to brand-name Corporate Social Responsibility (CSR) parameters, have joined associations that verify (through a monitoring and audit system) that management does not exploit labour. There have been no reports of violations of codes of conduct concerning Malaysian workers but for foreign workers on contract there are certain areas that have been reported. These areas, including trade union membership, the withholding of workers' passports and unsuitable accommodation, generally escape notice because auditors who monitor factory compliance do not question the terms of contracts as long as they comply with national labour standards. This paper is based on research with foreign workers in Malaysia and argues that despite the success of the anti-sweatshop movement in a global context, the neo-liberal state in Malaysia continues to place certain restrictions on transnational labour migrants which breach garment industry codes of conduct. Available evidence does not support the assumption that CSR practices provide sufficient protection for both citizen and foreign workers on contract in the garment industry.

Asbestosis in an asbestos composite mill at Mumbai: A prevalence study

PubMed Central

Murlidhar, V; Kanhere, Vijay

2005-01-01

Background Of an estimated 100000 workers exposed to asbestos in India, less than 30 have been compensated. The reasons for such a small number are: refusal by management sponsored studies to grant medical certifications to workers suffering from occupational diseases, lack of training for doctors in diagnosis of occupational lung diseases, deliberate misdiagnosis by doctors of asbestosis as either chronic bronchitis or tuberculosis and the inherent class bias of middle class doctors against workers. The aim of the study was to identify workers suffering from Asbestosis (parenchymal and pleural non-malignant disease) among the permanent workers of the Hindustan Composites Factory and assess their disability and medically certify them, whereupon they could avail of their basic rights to obtain compensation and proper treatment. Methods The study was conducted by the Occupational Health and Safety Centre and the Workers' Union. Asbestosis was diagnosed if they had an occupational history of asbestos exposure for at least 15 years and showed typical radiographic findings. Results Of 232 workers in the factory, 181 participated in the survey. 22% of them had asbestosis. All the asbestos affected workers had at least 20 years of exposure. 7% had rhonchi, 34% had late basal inspiratory rates, 82% had more than 80% of Forced Expiratory Volume in the first second (FEV1)/Forced Vital capacity (FVC) ratio and 66% had FVC less than 80% of the predicted value. On radiology 7% had only pleural disease, 10% had both pleural and parenchymal disease and 82% had only parenchymal disease. The association of pleural disease with chest pain was statistically significant. Conclusion We found the prevalence of asbestosis among exposed workers to be less than that anticipated for the number of years of exposure due to "Healthy Worker Effect". We suggest that all affected asbestos workers (including those who have been forced to leave) in India be medically certified and compensated. We also recommend better control of asbestos use in India. We also implore the management to provide all information about the work process and its hazards, conduct medical checkups as mandated by law and give the medical records to the workers.

3-(Bromomethyl)-2-chloro-4-(methylsulfonyl)-benzoic acid (BCMBA) has not previously been identified as a respiratory sensitiser. We detected two cases who presented respiratory and urticaria symptoms related to BCMBA and had positive skin prick tests to the agent. Subsequently, we conducted outbreak investigations at the BCMBA-producing factory and performed clinical examinations to confirm occupational diseases. The outbreak investigations included observations of work processes, assessment of exposure, a medical survey with a questionnaire and skin prick tests with 0.5% BCMBA water solution on 85 exposed workers and 9 unexposed workers. We used specific inhalation or nasal challenge and open skin application test to investigate BCMBA-related occupational asthma, rhinitis and contact urticaria. We identified nine workers with respiratory and/or skin symptoms and positive skin prick tests to BCMBA in a chemical factory. A survey among chemical factory workers indicated a BCMBA-related sensitisation rate of 8% among all exposed workers; the rate was highest (25%) among production workers in the production hall. Sensitisation was detected only in workers with the estimated highest exposure levels. Six cases of occupational asthma, rhinitis and/or contact urticaria caused by BCMBA were confirmed with challenge tests. Asthma-provoking doses in specific inhalation challenges were very low (0.03% or 0.3% BCMBA in lactose). We identified a new low molecular weight agent causing occupational asthma, rhinitis and contact urticaria. A typical clinical picture of allergic diseases and positive skin prick tests suggest underlying IgE-mediated disease mechanisms. Stringent exposure control measures are needed in order to prevent BCMBA-related diseases. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

"Controlling ourselves, by ourselves": risk assemblages on Malaysia's assembly lines.

PubMed

Root, Robin

2008-01-01

Since the early 1990s, the Malaysian government has identified factories as high risk for HIV and AIDS. Signaling epidemiological concerns over the rising rates of HIV among factory workers, a significant proportion of whom are women, the label also appeared to reconstitute stereotypes of factory women as dangerously sexual and of factories as immoral spaces. Drawing on ethnographic research in the export processing zones of Penang, Malaysia in the mid-1990s, I examine the meanings and experiences of HIV risk among factory women themselves. Data were analyzed using discourse and grounded theory methods, the former to identify women's multiple modes of rationalizing HIV risks, and the latter to theorize the sources and significance of women's HIV risk assemblages. The heuristic of assemblages as localized knowledge spaces helped to show that biomedical and socioreligious risk lexica operated not as fixed epistemological categories but as situational resources in women's risk scripts. Overall, women desired multiple risk knowledges to help them "control themselves by themselves," a project of reflexive self-shaping mediated by the diverse and discordant discourses of gender, ethnicity, and modernity in Malaysia that shaped how HIV risks were engendered and experienced.

To disclose the effects of chromium (Cr) on olfactory function, olfactory threshold tests were conducted on 27 male plating workers (Cr workers) with signs and symptoms of olfactory irritation but without nasal septum perforation or ulcer and on 34 male control subjects in Korean plating factories. The Cr workers had been exposed to Cr fume for 0.9 to 18.2 (mean 7.9) years; their blood Cr concentrations (0.16-3.69, mean 1.29 microg/dl) were significantly higher than those of the 34 control subjects (0.04-1.95, mean 0.55 microg/dl). Scores on recognition thresholds among the Cr workers were significantly higher than those of the control subjects (p < 0.05) and related positively and significantly to the exposure periods of the 27 Cr workers (p < 0.05). Olfactory thresholds were not significantly different between the Cr workers with and without nasal signs or symptoms, except that the scores on the recognition threshold were significantly higher in those experiencing difficulty with smell (p < 0.05). It is suggested that olfactory threshold is affected by Cr without development of nasal septum perforation or ulceration.

Bangladesh has made significant progress in reducing maternal mortality. Many factors have contributed to this; one is the socio-economic development of the country. The ready-made garment industry is at the forefront of this development creating employment for many women. However, the work environment has the potential to create health problems, particularly for vulnerable groups such as pregnant women. This paper explores perceptions of health problems during pregnancy of factory workers, in this important industry in Bangladesh. This study was conducted in four factories using qualitative research methods to provide a view of pregnant workers' health risks beyond a bio-medical approach. Data was collected through in-depth interviews of pregnant workers and observations of their homes and workplaces. Further, key informant interviews with factory health care providers, government officials and employers revealed different perspectives and experiences. Data was collected in the local language (Bengali), then transcribed and analysed using a framework analysis approach. Female workers reported that participation in paid work created an opportunity for them to earn money but pregnancy and the nature of the job, including being pressured to meet the production quota, pressure to leave the job because of their pregnancy and withholding of maternity benefits, cause stress, anxiety and may contribute to hypertensive disorders of pregnancy. This was confirmed by factory doctors who suggested that developing hypertensive disorders during pregnancy was influenced by the nature of work and stress. The employers seemed focused on profit and meeting quotas and the health of pregnant workers appeared to be a lower priority. This study found that the government lacks the resources to understand the extent of the problem or the level of compliance with maternity related regulations. These results indicate the vulnerability of female workers to physical and mental stress at work and associations with their health problems during pregnancy. It identifies the deficiencies of family, workplace and health service support for these pregnant workers, highlighting the urgent need for government and non-government organisations to work with this important export industry to improve health surveillance and monitoring and the enforcement of existing laws to protect the rights and conditions of pregnant women.

To report the cases of four patients with bronchiolitis caused by exposure to artificial butter flavoring at a cookie factory in Brazil. We described the clinical, tomographic, and spirometric findings in the four patients, as well as the lung biopsy findings in one of the patients. All four patients were young male nonsmokers and developed persistent airflow obstruction (reduced FEV1/FVC ratio and FEV1 at 25-44% of predicted) after 1-3 years of exposure to diacetyl, without the use of personal protective equipment, at a cookie factory. The HRCT findings were indicative of bronchiolitis. In one patient, the surgical lung biopsy revealed bronchiolitis obliterans accompanied by giant cells. Bronchiolitis resulting from exposure to artificial flavoring agents should be included in the differential diagnosis of airflow obstruction in workers in Brazil.

Headache disorders are the most common complaints worldwide. Migraine, tension-type and cluster headaches account for majority of primary headaches and impose a substantial burden on the individual, family or society at large. The burden is immense on workers, women and children in terms of missing work and school days. There are few studies that show relatively lower prevalence of primary headaches in Africa as compared to Europe and America. There might be many reasons for this lower prevalence. The objective of this study is to determine the prevalence and burden of primary headaches among the Akaki textile factory workers, which may provide data for the local and international level toward the campaign of lifting the burden of headache worldwide. The overall 1-year prevalence of all types of primary headaches was found to be 16.4%, and that of migraine was 6.2%. The prevalence of migraine in females was 10.1% while it was 3.7% in males. The prevalence of tension-type headaches was found to be 9.8%. This was 16.3 % in females as compared to 5.7% in males. The burden of the primary headaches in terms of lost workdays, gross under recognition and absence of effective treatment is tremendous. In conclusion, the prevalence of primary headaches in the Akaki textile mill workers is significant, particularly in females, and the burden is massive, in a place of poverty and ignorance. We recommend the availability and administration of specific therapy to the factory workers with primary headaches, and community based well-designed study for the whole nation's rural and urban population.

China is facing an emerging epidemic of syphilis, and the cities in south China are most affected. Knowledge is a key factor in the prevention of syphilis infection, however, little is reported about how much people know about syphilis. This study was aimed at assessing peoples' awareness status in a city located in south China. Six populations were recruited for this study, including urban residents, factory workers, college students, pregnant women, female sex workers (FSWs), and men who have sex with men (MSM). A questionnaire designed by the National Center for Disease Control and Prevention was used to assess participants' awareness of syphilis knowledge. About 5% of participants were randomly selected to conduct a telephone survey for confirming the validity of fieldwork. The study recruited 3470 participants, and 61.2% of participants were assigned to the awareness group. College students had the smallest percentage of awareness at 51.7% (371/718), followed by FSWs at 53.9% (200/371), factory workers at 56.0% (381/679), urban residents at 65.4% (435/665), pregnant women at 66.0% (451/683), and MSM at 81.1% (287/354). Multivariate logistic regression analysis showed that MSM and FSWs-but not factory workers and pregnant women-had more awareness of syphilis knowledge when comparing with urban residents; however, college students presented less awareness of syphilis knowledge than urban residents. Participants of younger age, of female gender, with lower education levels and without Shenzhen hukou possessed less awareness of syphilis knowledge than those of older age, of male gender, with higher education levels and with Shenzhen hukou respectively. The percentages of awareness on syphilis knowledge found in this study are far from the benchmark set in the national 10-year plan. Tailored interventions for different subgroups to increase syphilis awareness are urgently warranted.

Due to increasing usage of chemicals in various industries, occupational exposure of women with these materials is unavoidable. Nowadays, some studies indicate adverse effects of exposure to these chemicals, especially organic solvents on the reproductive system of females. This study aimed to assess the relationship between spontaneous abortion and occupational exposure to organic solvents mixture in pharmaceutical industry. This study was carried out in a pharmaceutical factory located in the suburb of Tehran in 2010. During the study, married women who were working in the factory laboratory units and had exposure to mixed organic solvents were compared with married women who were working in the packing units of the factory without occupational exposure to organic solvents in terms of spontaneous abortion frequency and duration of pregnancy using statistical methods. In this study, the frequency of spontaneous abortion in employees with and without exposure to organic solvents mixture was 10.7 and 2.9% respectively. This study showed that even after adjustment for confounding factors, there was a significant correlation between spontaneous abortion and occupational exposure to organic solvents mixture and this correlation increased with increasing levels of exposure to organic solvents. Also, a significant correlation was observed between occupational exposure to mixed organic solvents and waiting time to become pregnant (TTP). Furthermore, this study showed that even after adjustment for confounding variables, shift workers were significantly more affected by spontaneous abortion compared to daytime workers (P < 0.001). Also, in our study, synergistic effect between shift working and occupational exposure to organic solvents mixture on spontaneous abortion was seen. According to the results of this study, since there is probability of spontaneous abortion resulting from occupational exposure to various chemicals including organic solvents, recommendation to review the status of occupational exposure of workers can be helpful in improving fertility consultations and reproductive health.

Fiberglass is extensively used due to its properties of thermal, acoustic and electrical insulation, and also to reinforce other materials such as plastics. Irritant contact dermatitis to fiberglass is a well established occupational dermatose and is due to penetration of small fragments in the cornified layer of the skin. On the other hand, allergic contact dermatitis (ACD) is rare and is more often triggered by sensitivity to the additives and resins used in the manufacture of fiberglass products. We report a case of ACD to fiberglass in a factory worker of fiberglass reinforced products.

Exposure to asbestos minerals has been associated with a wide variety of adverse health effects including lung cancer, pleural mesothelioma, and cancer of other organs. It was shown previously that asbestos samples collected from a local asbestos factory enhanced sister chromatid exchanges (SCEs) and chromosomal aberrations in vitro using human lymphocytes. In the present study, 22 workers from the same factory and 12 controls were further investigated. Controls were matched for age, sex, and socioeconomic state. The peripheral blood lymphocytes were cultured and harvested at 48 hours for studies of chromosomal aberrations and at 72 hours for SCE frequency determinations. Asbestos workers had a raised mean SCE rate and increased numbers of chromosomal aberrations compared with a control population. Most of the chromosomal aberrations were chromatid gap and break types.

Detailed mappings of the external exposures which can be received by the workers in two NORM industrial factories located at the South-West of Spain have been performed: one devoted to the production of phosphoric acid, and the other devoted to the production of titanium dioxide pigments. In most places of the analyzed factories, the external exposures are moderated, although in some specific points, and associated to the presence of scales, their values are clearly higher. Nevertheless, under normal running conditions, the contribution of the external exposures to the effective doses received by the workers is lower than 1 mSv/y becausemore » the worker occupancy factors values are very low in the places with the highest external exposures.« less

The Majority of the Migrant Factory Workers of the Light Industry in Shenzhen, China May Be Physically Inactive

PubMed Central

Lau, Joseph T. F.; Wu, Anise M. S.; Tse, Vincent W. S.; Zhou, Shenglai

2015-01-01

Physical inactivity is a strong risk factor of non-communicable diseases (NCD). In China, there are 250 million migrant factory workers, who are susceptible to physical inactivity and hence NCD because of work nature and setting. With random stratified sampling, 807 such workers of the light industry were recruited in Shenzhen, China and completed a self-administered questionnaire with informed consent. The prevalence of inadequate physical activity (defined according to the World Health Organization’s recommendation on level of moderate/vigorous physical activity) was 95.4%. Of all participants, 69.1% showed “a very low level of physical activity” (VLLPA), defined as ≤30 minutes of weekly moderate/vigorous physical activity, which was significantly associated with female sex (Odds ratio [OR]=1.65), lower education level (OR=0.10 to 0.33, primary education as the reference group) and married status (OR=0.63, single status as the reference group). Adjusted for these factors, perceived social support (Adjusted OR=0.87) was negatively associated with VLLPA, while job stress due to workload, which was significant in the univariate analysis (OR=0.98), became non-significant (p=0.184). Significant interaction between perceived social support and perceived job stress onto VLLPA was found (p=0.044), implying that the negative association between job stress and VLLPA, which might reflect a potential response to cope with stress by performing exercises, was stronger among those with weaker social support. The extremely low level of physical activity rings an alarm, as it implies high risk of NCD, and as there are no existing programs promoting physical activity in this group. Interventions need to take into account social support, potential coping to job stress, and structural factors of the factory setting, while involving factories’ management. PMID:26244514

The association of malignant mesothelioma (MM) and nonoccupational asbestos exposure is currently debated. Our study investigates environmental and domestic asbestos exposure in the city where the largest Italian asbestos cement (AC) factory was located. This population-based case-control study included pleural MM (histologically diagnosed) incidents in the area in 1987-1993, matched by age and sex to two controls (four if younger than 60). Diagnoses were confirmed by a panel of five pathologists. We interviewed 102 cases and 273 controls in 1993-1995, out of 116 and 330 eligible subjects. Information was checked and completed on the basis of factory and Town Office files. We adjusted analyses for occupational exposure in the AC industry. In the town there were no other relevant industrial sources of asbestos exposure. Twenty-three cases and 20 controls lived with an AC worker [odds ratio (OR) = 4.5; 95% confidence interval (CI), 1.8-11.1)]. The risk was higher for the offspring of AC workers (OR = 7.4; 95% CI, 1.9-28.1). Subjects attending grammar school in Casale also showed an increased risk (OR = 3.3; 95% CI, 1.4-7.7). Living in Casale was associated with a very high risk (after selecting out AC workers: OR = 20.6; 95% CI, 6.2-68.6), with spatial trend with increasing distance from the AC factory. The present work confirms the association of environmental asbestos exposure and pleural MM, controlling for other sources of asbestos exposure, and suggests that environmental exposure caused a greater risk than domestic exposure.

Tobacco control and cessation interventions are among the most cost effective medical interventions but health systems in low resource countries lack the infrastructure to promote prevention and cessation among tobacco users. Workplace settings have the potential to provide opportunities and access for tobacco prevention interventions. This is a single group study evaluating tobacco use prevention and cessation through a structured three stage intervention program for tobacco users comprising education on harmful effects of tobacco, oral cancer screening and behavior therapy for tobacco cessation at the worksite. All the 739 workers who were invited participated in tobacco awareness program and were screened for oral pre cancer lesions. 291 (39.4%) workers were found to be users of tobacco in some form. Education, gender and alcohol use (p<0.0001) were some of the factors associated with tobacco user status. The prevalence of clinical oral precancer lesions among tobacco users was 21.6%. Alcohol consumption (p<0.001), the type of tobacco consumed (p<0.018), personal medical history of chronic diseases (p<0.007) and combined use of alcohol and tobacco (p<0.001) were some factors found to be associated with presence of oral pre cancer lesions. An integrated approach for worksite based tobacco use prevention with oral cancer screening program showed good acceptance and participation and was effective in addressing the problem of tobacco consumption among the factory workers.

Background Humans living near industrial point emissions can experience high levels of exposures to air pollutants. Map Ta Phut Industrial Estate in Thailand is the location of the largest steel, oil refinery, and petrochemical factory complexes in Southeast Asia. Air pollution is an important source of oxidative stress and reactive oxygen species, which interact with DNA and lipids, leading to oxidative damage and lipid peroxidation, respectively. Objective We measured the levels of malondialdehyde–deoxyguanosine (dG) adducts, a biomarker of oxidative stress and lipid peroxidation, in petrochemical workers, nearby residents, and subjects living in a control district without proximity to industrial sources. Design We conducted a cross-sectional study to compare the prevalence of malondialdehyde-dG adducts in groups of subjects experiencing various degrees of air pollution. Results The multivariate regression analysis shows that the adduct levels were associated with occupational and environmental exposures to air pollution. The highest adduct level was observed in the steel factory workers. In addition, the formation of DNA damage tended to be associated with tobacco smoking, but without reaching statistical significance. A nonsignificant increase in DNA adducts was observed after 4–6 years of employment among the petrochemical complexes. Conclusions Air pollution emitted from the Map Ta Phut Industrial Estate complexes was associated with increased adduct levels in petrochemical workers and nearby residents. Considering the mutagenic potential of DNA lesions in the carcinogenic process, we recommend measures aimed at reducing the levels of air pollution. PMID:20056580

The objective of this study was to determine the prevalence rate and possible aetiological factors of premalignant skin lesions observed among paraquat manufacturers. A total of 228 workers in 28 factories were interviewed and independently examined by a dermatologist during site inspection in 1985. Information concerning past working experience, current toxic exposures, other risk factors of hyperpigmented macules and keratosis, and the past and present manufacturing processes of each factory was collected. Sixty nine cases of hyperpigmented macules and 17 of hyperkeratosis were found. Typical macules were irregular in shape, pin head size, hyperpigmented, with or without hyperkeratosis, and usually distributed symmetrically over the forearms, hands, neck, and upper chest, where exposure to sunlight was maximal. Six patients with hyperkeratotic lesions subsequently had biopsies performed and two showed Bowenoid changes. Eighty per cent (28 cases) and 67% (38 cases) of workers developed hyperpigmented macules if they had ever been engaged in bipyridine centrifugation and crystallisation, respectively; there were three workers 3% with such lesions among those who performed packaging or administrative jobs, or both. There was a significant trend (p less than 0.0001) for workers to develop hyperpigmented macules and hyperkeratosis the longer they had been exposed to centrifugation or crystallisation, or both, independent of age and the duration of exposure to sunlight. Evidence is presented to suggest that sunlight is a necessary cofactor and that the aetiological agent was produced during high temperature sodium process of bipyridine synthesis, and possibly bipyridine isomer(s).

A cross-sectional survey of the wood furniture industry was conducted in southern Thailand in February 1993. The aim was to examine the manufacturing process, occupational hazards at the workplace, workers' demographic characteristics, period of employment, incidence rate of work related injury and some reproductive history of workers. Altogether 69 managers and 1,000 workers participated in the study. There are 2 main types of wood industry, rubberwood and hardwood. The rubberwood industry is semi-automated with advanced technology, has a female-dominated workforce of 200-300 workers per factory and overseas-market orientation. The hardwood industry is based in small-scale workplaces ranging from 20 to 60 workers, domestic-market orientation and has a male-dominated workforce. Most of the workers were young, single, of low education and were high turnover rate laborforce, with arduous work and long working hours per week. Solvent was the most frequent chemical exposure. The person-year incidence of chemical exposure in female workers was higher than in male workers for every group of chemicals. The incidence of accidents was twice as high as the official rate. The standardized fertility ratio of female wood workers was only 51.6% of that of the Thai female population. There was a high abortion rate among women who became pregnant inside the wood industry compared to that among pregnancies outside the wood factory. Wood industry workers were exposed to occupational hazards and accident-prone work conditions.

Health and safety training program has been applied to prevent work-related musculoskeletal disorders (MSDs) in workplace. We evaluated the effectiveness of participatory training and didactic training programs on MSD prevention among frontline workers in Shenzhen, China. The authors randomly assigned 918 workers from intervention factories to receive participatory training (intervention group), and 907 workers from intervention factories and 1,654 workers from control factories to receive didactic training (control_1 group, control_2 group, respectively) from June 1, 2008 to November 30, 2009. Participants were asked to report experience of ache, pain or discomfort in 10 body parts at baseline and 1 year after training. Data were analyzed to compare the MSD prevalence 1 year before and 1 year after training in different groups from 2009 to 2010. The follow-up rate was 61 % (2,120/3,479) at 1 year after training. In the year after training, there were no statistically significant changes in the proportion of workers who reported MSD in any body part. MSD prevalence rates in the intervention group reduced from 16.8 to 9.9 % for lower extremities (χ(2) = 13.102, p < 0.001) and from 12.9 to 8.3 % (χ(2) = 9.433, p = 0.002) for wrist and finger at 1 year after training. However, the rates did not change significantly for upper back, lower back, neck, shoulder and elbow in the intervention group and for all 10 body parts in two control groups. Overall, the training programs did not seem to prevent the occurrence of MSD among frontline workers. However, participatory training might be effective to reduce MSD in the lower extremities and wrist and finger.

Global literature has suggested a negative impact of acculturative stress on both physical and mental health among international migrants. In China, approximately 20 percent of its population is rural-to-urban migrant workers and there are significant cultural differences between rural and urban societies, but no data are available regarding the acculturative stress of Chinese migrant workers. This study aimed to explore the forms and contexts of acculturative stress among Chinese migrant workers. Qualitative data were collected from four focus group discussions with 17 Chinese rural-to-urban migrant workers and three individual interviews with three medical professionals who provided mental health services for factory-workers in Shenzhen, China. The data in the current study showed that rural-to-urban migrant workers in China had experienced various forms of acculturative stress including difficulties in adapting to the environment, work-related stress, family-related stress, financial hardship, and lack of sense of belonging to cities. Rural-to-urban migration in China is a challenging transition with significant acculturative stress and demands for major adjustments among migrant workers. The assessment and management of acculturative stress is a necessary first step in providing mental health services to migrant workers.

1992-01-01

Comparative analysis of some basic lung indices obtained from a screening investigation of the flow volume curve by using two techniques, with a nose clip and without a nose clip, was made on a cohort of 86 workers in a factory shop for the production of bearings. We found no statistically significant differences between the indices obtained by the two techniques. Our study showed that the FVC and FEV1 obtained in workers without using nose clips were equal to or better than those obtained using nose clips in 60% of the workers. The reproducibility of the two methods was similar. The analysis of the data has shown that the flow volume curve investigation gives better results when performed without a nose clip, especially in industrial conditions.

To study job stress and upper limb biomechanical overload due to repetitive and forceful manual activities in a factory producing high fashion clothing. A total of 518 workers (433 women and 85 men) were investigated to determine anxiety, occupational stress (using the Italian version of the Karasek Job Content Questionnaire) and perception of symptoms (using the Italian version of the Somatization scale of Symptom Checklist SCL-90). Biomechanical overload was analyzed using the OCRA Check list. Biomechanical assessment did not reveal high-risk jobs, except for cutting. Although the perception of anxiety and job insecurity was within the normal range, all the workers showed a high level of job strain (correlated with the perception of symptoms) due to very low decision latitude. Occupational stress resulted partially in line with biomechanical risk factors; however, the perception of low decision latitude seems to play a major role in determining job strain. Interactions between physical and psychological factors cannot be demonstrated. Anyway, simultaneous long-term monitoring of occupational stress features and biomechanical overload could guide workplace interventions aimed at reducing the risk of adverse health effects.

The application of data mining to explore association rules between metabolic syndrome and lifestyles.

PubMed

Huang, Yi Chao

This study used an efficient data mining algorithm, called DCIP (the data cutting and inner product method), to explore association rules between the lifestyles of factory workers in Taiwan and the metabolic syndrome. A total of 1,216 workers in four companies completed a lifestyle questionnaire. Results of the questionnaire survey were integrated into the workers' health examination reports to form an attribute database of the metabolic syndrome. Among the association rules derived by DCIP, 80% of those on the list of the top 15 highest support counts are corroborated by medical literature or by healthcare professionals. These findings prove that data mining is a valid and effective research method, and that larger sample sizes will likely produce more accurate associations connecting the metabolic syndrome to specific lifestyles. The rules already verified can serve as a reference guide for the health management of factory workers. The remaining 20%, while still lacking hard evidence, provide fertile ground for future research.

The purpose of this study was to evaluate grouping schemes for exposure to total dust in cement industry workers using non-repeated measurement data. In total, 2370 total dust measurements taken from nine Portland cement factories in 1995-2009 were analyzed. Various grouping schemes were generated based on work process, job, factory, or average exposure. To characterize variance components of each grouping scheme, we developed mixed-effects models with a B-spline time trend incorporated as fixed effects and a grouping variable incorporated as a random effect. Using the estimated variance components, elasticity was calculated. To compare the prediction performances of different grouping schemes, 10-fold cross-validation tests were conducted, and root mean squared errors and pooled correlation coefficients were calculated for each grouping scheme. The five exposure groups created a posteriori by ranking job and factory combinations according to average dust exposure showed the best prediction performance and highest elasticity among various grouping schemes. Our findings suggest a grouping method based on ranking of job, and factory combinations would be the optimal choice in this population. Our grouping method may aid exposure assessment efforts in similar occupational settings, minimizing the misclassification of exposures. © The Author 2015.

Assessment and evaluation of the health-related quality of life of industrial workers is an important research focus. This descriptive correlational study identifies the predictors of health-related quality of life using a random sampling of industrial workers (n = 640) from construction factories in Amman Governorate in Jordan using demographic characteristics, a health and work-related factors questionnaire, and the World Health Organization Quality of Life-Brief scale. Results showed that industrial workers had good physical health but a poor working environment. There was a statistically significant relationship between educational level, conflict between work and individual life and work and social life, working hours, and workload, and all domains of health-related quality of life. Overall, educational level was the main predictor for all domains of health-related quality of life. Such results confirm the need to develop appropriate interventions and strategies to improve workers' health-related quality of life. Furthermore, developing an integrated approach among policymakers, employers, and work organizations to enhance industrial workers' occupational health programs could be effective. © 2017 John Wiley & Sons Australia, Ltd.

2010-07-01

To determine site-specific cancer incidence among women spinning-weaving and dyeing-finishing workers in the largest flax textile factory in Lithuania. The cancer incidence of a cohort of 3447 women workers from a flax textile factory was investigated for the period 1978-2002. All subjects were employed at the plant in the period 1957-2000 for a minimum of 12 months. Standardised incidence ratios (SIRs) were estimated by use of the corresponding national rates. SIRs were calculated for the spinning-weaving and dyeing-finishing work categories, and for two durations of employment categories (<10 years, > or =10 years). The cancer SIRs among spinning-weaving and dyeing-finishing workers were 0.84 (95% CI 0.69 to 1.00) and 0.90 (95% CI 0.52 to 1.44). An incidence deficit for non-melanoma skin cancer was found for the spinning-weaving unit (SIR 0.45, 95% CI 0.18 to 0.92). The risk of oral cavity and pharynx cancer was significantly increased in spinning-weaving unit workers with <10 years of employment (SIR 5.71, 95% CI 1.56 to 14.60). A significant excess of thyroid cancer and nervous system cancer was found among dyeing-finishing workers. The overall cancer and non-melanoma skin cancer incidence rate among flax spinning-weaving workers was lower compared with the Lithuanian population. The present findings lend some support to an excess of thyroid and nervous system cancers among dyeing-finishing workers and of oral cavity and pharynx cancer in spinning-weaving workers.

Worker programs and resource use: Evidence from better work jordan

NASA Astrophysics Data System (ADS)

Robins, Nathan

This paper examines data collected for the Better Work program in Jordan which aims to protect laborers in the garment industry from poor working conditions. Data are examined to look for benefits to the factories participating in the program beyond improved compliance with labor law. In particular, potential impacts to firm energy use are examined and correlations are tested between electricity use rates and measures of worker outcomes and a number of factory traits such as size and production input costs. Evidence was found to back up work done in Vietnam with regard to resource use and distribution of electricity expenses. It was also found that the type of data being collected is not ideal for examinations of energy, and more direct methods are desirable, and that considerable production obstacles are worker skill level, electricity prices, and to a greater degree in Jordan than in previously examined countries, water prices.

Altogether 14,650 workers employed at least for 1 year a the textile factory in Alytus, Lithuania, were included in the cohort and followed during the period from 1978 to 1997. The standardized incidence ratio (SIR) for men was 1.28. The incidence of esophagus cancer was significant higher (SIR 3.42). It increased only slightly for lung (SIR 1.35). In the women cohort, SIR was 1.05. However, there was a significant increase of the incidence of gallbladder cancer (SIR 3.19). Among textile-processing (spinning and weaving departments) women workers, we found elevated total cancer incidence (SIR 1.35), incidence of breast cancer (SIR 1.49), and cervical cancer (SIR 1.82). In this cohort increased SIR values were observed for more than 10 years since first exposure for all cancer (SIR 1.70) and cervical cancer (SIR 2.44).

Thaumatin is a sweetener and flavor modifier commonly used in the food industry. Likewise, gum arabic is widely used as a food stabilizer and thickening agent. We report here that a powder mixture composed of 10% thaumatin and 90% gum arabic led to allergic symptoms in the upper airways in occupationally exposed individuals: four of eight workers of a chewing gum factory exposed to this powder mixture had pronounced rhinitis. A positive skin prick test result for pure thaumatin was obtained in all four individuals with rhinitis of whom two also had a positive skin prick test result for pure gum arabic and gum arabic-specific IgE. Subsitution of a powdered thaumatin with a liquid form reduced symptoms among the rhinitic workers. Although gum arabic is a well-known potential allergen, we were unable to find prior documentation of allergic symptoms to thaumatin when it is used in the food industry. © 2017 Wiley Periodicals, Inc.

2007-11-01

This article explores the extent of, and factors associated with, sexual harassment of young female migrant workers in the carpet and garment factories in Kathmandu Valley. Information is drawn from a survey of 550 female workers aged 14 to 19 and 12 in-depth case histories. Bivariate and multivariate techniques were applied to identify the factors associated with harassment. The survey found that 1 in 10 young women had experienced sexual harassment or coercion. Those who were exposed to pornographic movies were more likely than those with no exposure to any kind of movies to report sexual harassment. Perpetrators included coworkers, boyfriends, employers, and relatives. Case histories revealed that the inability of young women to communicate effectively with their peers and sex partners, lack of self-esteem, job insecurity, and other socioeconomic problems made them vulnerable to these abuses. The results suggest the need for advocacy and a range of factory-based interventions.

2002-01-01

This paper explores workers' experiences and understandings of occupational health hazards in the electronics industries of northern Thailand. Women form the bulk of the lower-level workforce as operators responsible for assembling the parts that make up microchip components. Drawing data from 16 months of research in workers' dormitories, formal and informal interviews and questionnaire surveys, in this paper I explore how gender relations are central to the organization and experience of work in these industries. I identify "work process" health hazards resulting from the physical working environment, and "workplace" health hazards relating to the organizational and social pressures of the working environment. Musculoskeletal pain, eye strain, chemical exposure, stress, improper use of safety equipment and accidents all impact upon women workers' health. Additionally, risk behaviors such as amphetamine and alcohol use, and unprotected sex, are associated with the social context of factory work.

This article examines data from a study on garment-factory workers in Bangladesh to explore the implications of work for the early socialization of young women. For the first time, large numbers of young Bangladeshi women are being given an alternative to lives in which they move directly from childhood to adulthood through early marriage and childbearing. Employment creates a period of transition in contrast to the abrupt assumption of adult roles at very young ages that marriage and childbearing mandate. This longer transition creates a period of adolescence for young women working in the garment sector that is shown to have strong implications for the women's long-term reproductive health.

In cooperation with the IRCCS Fondazione Maugeri and the IRCCS Fondazione Ospedale Maggiore Policlinico - EPM-CEMOC, of Milan, the Local Health Unit in Bari, Italy carried out a research project, sponsored partly by the Italian Ministry of Health, on upper limb work-related musculoskeletal disorders (UL-WMSDs) in a specific manufacturing sector, the upholstered furniture industry. This "sofa district" is widely represented with approximately 14,000 workers and 500 factories over a wide geographic area of southern Italy. Advanced technology in the manufacturing process is combined with workers performing intensive arm-hand tasks. The aim of the study included: a) assessment of exposure to repetitive strain and movements of the upper limb in a representative sample of the factories using the OCRA method, b) analysis of the annual prevalence and incidence rates, c) definition of possible improvement via ergonomic solutions in the various factories. Via a network of occupational physicians a total of more than 6000 subjects were examined over a 5-year period. Case-definition was assessed through standardized procedures. A detailed description of the manufacturing process of the upholstered furniture industry and of the characteristics of the working population is provided Exposed groups at risk were:filling preparation workers, leather-cutting operators, sewing and upholstery-assembly workers. Data collected in private companies of different size in this extensive industrial "sofa area" emphasize the importance of prevention through adequate ergonomic solutions and the need to improve training programmes covering the whole area.

This study estimates job-related risks among common low wage occupations (cleaning, construction, food service, cashier/baggers, and factory workers) held by predominantly Haitian, El Salvadorian, and Brazilian immigrants living or working in Somerville, Massachusetts. A community-based cross-sectional survey on immigrant occupational health was conducted between 2006 and 2009 and logistic regression was used to assess the job-related risks among the most common low wage occupations. Construction workers reported significantly higher health risks, and lower access to occupational health services than the other occupations. Compared to cashier/baggers, the reference population in this study, cleaners reported significantly lower access to health and safety and work training and no knowledge of workers' compensation. Factory workers reported significantly lower work training compared to cashier/baggers. Food service workers reported the least access to doctors compared to the other occupations. We found significant variability in risks among different low wage immigrant occupations. The type of occupation independently contributed to varying levels of risks among these jobs. We believe our findings to be conservative and recommend additional inquiry aimed at assuring the representativeness of our findings. © 2013 Wiley Periodicals, Inc.

In 2015, workers dismantling a fluorescent lamp factory in Korea were affected by mercury poisoning from exposure to mercury vapor. Eighteen out of the 21 workers who participated in the demolition project presented with symptoms of poisoning and, of these, 10 had persistent symptoms even at 18 months after the initial exposure to mercury vapor. Early symptoms of 18 workers included a general skin rash, pruritus, myalgia, sleep disturbance, and cough and sputum production. Following alleviation of these initial symptoms, late symptoms, such as easy fatigue, insomnia, bad dreams, and anxiety disorder, began to manifest in 10 out of 18 patients. Seven workers underwent psychiatric care owing to sleep disturbance, anxiety disorder, and depression, and three workers underwent dermatologic treatment for hyperpigmentation, erythematous skin eruption, and chloracne-like skin lesions. Furthermore, three workers developed a coarse jerky movement, two had swan neck deformity of the fingers, and two received care at an anesthesiology clinic for paresthesia, such as burning sensation, cold sensation, and pain. Two workers underwent urologic treatment for dysfunction of the urologic system and impotence. However, symptomatic treatment did not result in satisfactory relief of these symptoms. Awareness of the perils of mercury and prevention of mercury exposure are critical for preventing health hazards caused by mercury vapor. Chelation therapy should be performed promptly following mercury poisoning to minimize damage.

To examine the effect of autism spectrum (AS) tendencies and psychosocial job characteristics on health-related quality of life (HRQOL) among factory workers. A questionnaire survey was administered to 376 Japanese factory employees from the same company (response rate: 83.6%) in 2010. Psychosocial job characteristics, including job demand, job control, and social support, were evaluated using the Job Content Questionnaire (JCQ). AS tendencies was assessed using the Autism-Spectrum Quotient (AQ), and HRQOL was assessed using the Medical Outcomes Study Short-Form General Health Survey (SF-8). Associations were investigated using multiple logistic regression analysis adjusted for confounders. In the multivariate analysis, AQ was positively (odds ratio [OR]: 3.94; 95% confidence interval [CI]: 1.70-9.73) and social support in the workplace was inversely (OR: 0.25; 95% CI: 0.10-0.57) associated with poor mental HRQOL. No significant interaction was observed between AQ and JCQ subitems. Only social support was inversely associated with poor physical HRQOL (OR and 95% CI for medium social support: 0.45 and 0.21-0.94), and a significant interaction between AQ and job control was observed (p=0.02), suggesting that high job control was associated with poor physical HRQOL among workers with high AQ, whereas low job control tended to be associated with poor physical HRQOL among others. Our results suggest that AS tendencies have a negative effect on workers' HRQOL and social support is a primary factor in maintaining HRQOL. Moreover, a structured work environment can maintain physical HRQOL in workers with high AS tendencies since higher job control will be stressful.

Background: The establishment of staff canteens is expected to improve the nutritional situation of Cambodian garment workers. The objective of this study is to assess the nutritive value of low-price model lunch sets provided at a garment factory in Phnom Penh, Cambodia. Methods: Exemplary lunch sets were served to female workers through a temporary canteen at a garment factory in Phnom Penh. Dish samples were collected repeatedly to examine mean serving sizes of individual ingredients. Food composition tables and NutriSurvey software were used to assess mean amounts and contributions to recommended dietary allowances (RDAs) or adequate intake of energy, macronutrients, dietary fiber, vitamin C (VitC), iron, vitamin A (VitA), folate and vitamin B12 (VitB12). Results: On average, lunch sets provided roughly one third of RDA or adequate intake of energy, carbohydrates, fat and dietary fiber. Contribution to RDA of protein was high (46% RDA). The sets contained a high mean share of VitC (159% RDA), VitA (66% RDA), and folate (44% RDA), but were low in VitB12 (29% RDA) and iron (20% RDA). Conclusions: Overall, lunches satisfied recommendations of caloric content and macronutrient composition. Sets on average contained a beneficial amount of VitC, VitA and folate. Adjustments are needed for a higher iron content. Alternative iron-rich foods are expected to be better suited, compared to increasing portions of costly meat/fish components. Lunch provision at Cambodian garment factories holds the potential to improve food security of workers, approximately at costs of <1 USD/person/day at large scale. Data on quantitative total dietary intake as well as physical activity among workers are needed to further optimize the concept of staff canteens. PMID:28754003

This study investigated the intensity of cigarette consumption and its correlates in China among urban male factory workers, a cohort especially vulnerable to tobacco exposure, one that appears to have benefitted little from recent public health efforts to reduce smoking rates. Data were collected from men working in factories of Kunming city, Yunnan, China, who are current daily smokers (N = 490). A multinomial logistic regression was conducted to examine the factors in association with smoking intensity in light, moderate, and heavy levels. Light smoking correlated with social smoking, smoking the first cigarette later in the day, self-reported health condition, and quit intention. Heavy smoking was associated with purchase of lower priced cigarettes, difficulty refraining from smoking, and prehypertensive blood pressure. Even in regions where smoking is highly prevalent, even among cohorts who smoke heavily, variation exists in how cigarettes are consumed. Analyses of this consumption, with special consideration given to smoking intensity and its correlates, can help guide tobacco-control strategists in developing more effective interventions. © 2013 APJPH.

Monsanto Corp., a factory where monochlorobenzene (MCB) was produced; was surveyed. The factory employed 1300 persons, including 14 workers involved in MCB production. The factory produced over 100,000,000 pounds of MCB in a year. The MCB process equipment was outdoors, and no ventilation system was noted. Equipment consisted of a 10-year-old closed system. During most of the operation, the workers remained indoors in a control-room block house located in the middle of the MCB production facility. A portable, total organic vapor analyzer was used to sample vapor concentrations on the walk-through survey. Less than 3 parts per million (ppm) totalmore » hydrocarbons, calibrated as MCB were detected. Charcoal tube air samples were also collected for 4.5 hours in the MCB area. They were in the 1 to 2ppm range for benzene and MCB. The author concludes that there is insignificant exposure to MCB, but that the facility requires further investigation. The author recommends additional monitoring to determine combined solvent exposure and exposure to nitrochlorobenzene, one of the products derived from MCB.« less

Studies 1 and 2 assessed performance on a battery of dorsolateral prefrontal cognitive ability (D-PFCA) tests, personality, psychometric intelligence, and academic performance (AP) in 2 undergraduate samples. In Studies 1 and 2, AP was correlated with D-PFCA (r=.37, p<.01, and r=.33, p<.01, respectively), IQ (r=.24, p<.05, and r=.38, p<.01, respectively), and Conscientiousness (r=.26, p<.05, and r=.37, p<.01, respectively). D-PFCA remained significant in regression analyses controlling for intelligence (or g) and personality. Studies 3 and 4 assessed D-PFCA, personality, and workplace performance among (a) managerial-administrative workers and (b) factory floor workers at a manufacturing company. Prefrontal cognitive ability correlated with supervisor ratings of manager performance at values of r ranging from .42 to .57 (ps<.001), depending on experience, and with factory floor performance at pr=.21 (p=.02), after controlling for experience, age, and education. Conscientiousness correlated with factory floor performance at r=.23.

A positive association of socioeconomic position and health is well established in high-income countries. In poorer nations, however, higher income individuals often have more cardiovascular risk factors (including obesity) than do those with less income. Our study goal was to estimate the effects of receiving a living wage (340% higher income) on short-term changes in consumption and cardiovascular risk factors among low-wage workers in a middle-income country. This cross-sectional study matched workers at an apparel factory (n=105) in the Dominican Republic with those at a similar factory (n=99) nearby, 15 months after the intervention factory introduced a substantially higher living wage. Statistical matching on non-time varying individual characteristics (childhood health, childhood living conditions, work experience, demographic factors) strengthened causal inference. Primary outcomes were blood pressure (systolic and diastolic), pulse rate, body mass index and waist circumference. Secondary outcomes were dietary consumption and spending on services, consumables and durable goods. Receiving the living wage was associated with increased consumption of protein, dairy, soda and juice and sugars, but not with cardiovascular risk factors. Intervention factory workers spent more on grocery items and household durable goods. While having a higher income in a middle-income country might be expected to increase obesity and its associated health risks, the current study found no short-term negative associations. There may be possible longer-term negative health consequences of increases in consumption of soda, juice and sugars, however. It is important to consider complementary interventions to support healthy dietary intake in areas with increasing wages.

Tobacco dust mainly contains nitrosamines, which are readily absorbed by the body tissues like skin, respiratory epithelium, and mucous membrane of mouth, nose and intestines. Exposure to tobacco dust is known to affect the respiratory tracts in humans. In the present study, cytogenetic effects of exposure to tobacco dust are evaluated in 154 male tobacco factory workers and 138 age and sex matched controls by analysing chromosomal aberrations in their peripheral blood lymphocytes. The workers were in the age group of 20-55 years and were employed in the tobacco processing factory for 1-32 years. Heparinised blood samples were collected from workers and control subjects and lymphocyte cultures were carried out by using standard technique. Slides were prepared and 150 metaphases were screened for each sample for various structural and numerical types of abnormalities. A statistically significant increase was observed in the frequencies of chromosomal aberrations in non-smoking and smoking exposed groups when compared to the respective controls. An increase in the frequencies of chromosomal aberrations was also observed with increase in years of service in the exposed subjects.

To investigate the prevalence of vitamin A deficiency among adolescent female factory workers in Bangladesh, and examine the association between various factors and vitamin A status. A cross-sectional study. Garment factories in Dhaka city, Bangladesh. Three hundred and eighty eight adolescent girls aged 12-19 y from ten garment factories were selected randomly for the present study. Information on socio-economic conditions and usual pattern of dietary intake were obtained by interview. Anthropometric data and blood samples were collected following the interview. By NCHS reference standard, 15.5% of the participants were thin (< 90% Wt/Ht) and about 7% overweight (> 120% Wt/Ht). In about 56%, serum vitamin A level was below the adequate level of 1.05 mumol/l, with 14% having vitamin A deficiency (< 0.70 mumol/l). Forty four per cent of the participants were found to be anaemic (haemoglobin < 120 g/l). Food frequency data on vitamin A rich foods revealed that a large percentage of the participants do not take eggs (41%), milk (64%), liver (85%) and sweet pumpkin (85%); while about 40% of the girls take dark green leafy vegetables (DGLV) and 17% take small fish at least four servings a week. The girls who consumed four or more servings per week of DGLV had significantly higher serum vitamin A level than the girls who took three servings or less. There was a significant positive association between the level of serum vitamin A and frequency of intake of DGLV (r = 0.12; P = 0.023). When age, level of education, percapita income, haemoglobin concentration, serum protein concentration, menstruation at the time of blood collection, prevalence of current morbidity, frequency of intake of egg, milk, small fish, DGLV, liver and sweet pumpkin were accounted for by multiple regression analysis, a strong relationship was found for serum vitamin A concentration with age, menstruation, haemoglobin level and frequency of intake of DGLV. For every unit change in the frequency of consumption of DGLV, there was 0.013 mumol/l change in serum vitamin A level whilst taking other factors into account. The data show that there is a high prevalence of subclinical vitamin A deficiency among the adolescent female garment factory workers in Bangladesh, although the anthropometric indices suggest that they do not suffer from acute under nutrition. Consumption of DGLV appears to have an important relation with the vitamin A status of these girls.

Weekly dose of Iron-Folate Supplementation with Vitamin-C in the workplace can prevent anaemia in women employees

Joseph, Bobby; Ramesh, Naveen

2013-01-01

Objective: To assess if a weekly dose of iron and folic acid along with vitamin C, in the workplace would reduce the prevalence of anaemia. Methodology: A multi-pronged intervention was carried out to reduce the prevalence of anaemia among workers of 7 apparel manufacturing factories using a regime consisting of a supervised single dose of albendazole (400mg) followed by a weekly dose of dried ferrous sulphate (150mg), folic acid (0.5mg) and vitamin C (100mg). Workers were provided information on the causes of anaemia and its prevention. The total duration of the intervention was 16 weeks. Haemoglobin levels of a randomly selected sample of workers were tested before and after the intervention using a computerized non-cyan-meth-haemoglobin method. Results: Of the 10810 workers who were enrolled a sample of 515 workers was randomly selected for the blood investigations. At the end of the intervention (18 weeks after the first blood sample was collected) only 361 out of the 515 who had been enrolled a little more than 16 weeks earlier still remained in the factories and among women 279 out of 385 enrolled were still working in the factories. In the 385 unmatched samples the number of anaemic women had reduced from 141 before the intervention to 79 after - mean haemoglobin increasing from 12.2 to 13.0 (p < 0.001) and in the 279 paired samples prevalence of anaemia had reduced from 105 to 58 - mean haemoglobin increasing from 12.1 to 13.0 (p < 0.001). Conclusions: Our results demonstrated that in resource poor regions, where prevalence of anaemia is high, the workplace may be considered an ideal location to give a weekly supervised dose of iron, folic acid and vitamin C to effectively tackle the problem and probably improve worker efficiency.

A study on the oral health status of 198 factory workers (in Antara Steel, Pasir Gudang, Johor) was carried out in November 1986. The subjects were predominantly male (94%) and Malay (91%) with an average age of 27.4 years. The prevalence of caries was 87.4% with a mean DMFT of 7.1 + 5.4. There were 3 subjects with full upper, lower dentures and 16 subjects with partial dentures. Two subjects examined needed dentures but were not wearing them. Thirty five (17.7%) of those examined needed urgent extractions, and 8 needed emergency treatment for fillings. Enamel opacities were found in 141 subjects (75.6%) but only 9 were aware of these defects. Dental health was very poor with 72% examined needing scaling. Seventeen (9%) had gross supra and subgingival calculus. There was a total of 107 (54%) smokers and heavy nicotine stains were found in 41 (20.7%), of the population examined. Examination of soft tissues showed 111 (56%) subjects with recurrent aphthous ulcers whilst 15 (7.6%) suffered from herpes labialis. Five subjects (2.5%) suffered from denture stomatitis whilst the prevalence of other soft tissue lesions was very low.

Childhood leukaemia and ordnance factories in west Cumbria during the Second World War.

PubMed

Kinlen, L

2006-07-03

Much evidence has accumulated that childhood leukaemia (CL) is a rare response to a common, but unidentified, infection and in particular that situations involving the unusual mixing of urban and rural groups (approximating to, respectively, groups infected with, and susceptible to, the relevant microorganism) can produce localised epidemics with consequent increases of the infrequent leukaemic complication. During the Second World War, explosives production factories were built and operated at Drigg and Sellafield, and a shell filling factory at Bootle, in west Cumbria, England, requiring substantial numbers of construction workers to be brought into this remote and isolated area. Following the design of an earlier study of CL near large (post-war) rural construction sites, mortality from this disease was investigated with the help of the Office of National Statistics, in the area around these Cumbrian factories where local workers largely lived, during the construction period and with particular reference to the overlapping construction and operational phase when the mixing of local and migrant workers would have been greatest. An excess of leukaemia deaths at ages 1-14 was found during the construction period (observed 3; observed/expected (O/E) 2.2, 95% confidence interval (CI): 0.6, 6.0), which was more marked and statistically significant during the overlap with operations (O 3; O/E 4.5, 95% CI: 1.1, 12.2), especially at ages 1-4 (O 2; O/E 7.1, CI: 1.2, 23.6). A previous investigation did not detect this excess because it considered only a small part of west Cumbria that omitted the communities where most of the workforce lived, having incorrectly attributed the post-war expansion of the village of Seascale (situated between Drigg and Sellafield) to the wartime ordnance factories. The present findings are consistent with the results of the earlier study of rural construction projects and with the general evidence that marked rural-urban population mixing increases the risk of CL.

The upholstered furniture industry, the so-called "triangle of the sofa industry", is a geographic area of national and strategic economic importance in southern Italy. The single tasks are carried out mostly manually, with the characteristics of a handicraft approach. The aim of the survey was to assess the prevalence of upper limb work-related musculoskeletal disorders (UL-WMSDs) in 30 factories of the sofa industry located in a large geographic area of the Puglia and Basilicata Regions. In the period 1 January-31 December 2003 a network of occupational physicians investigated a population of 5.477 subjects (exposed n=3481, controls n=1996, M=3865, F=1612) in 30 different factories of the area. More than 60 percent of the total workforce studied was employed in large-sized companies (>500 employees). The following work tasks were considered: filling preparation workers, leather-cutting operators, sewing and upholstery-assembly workers. Case-definition was assessed through standardized procedures: symptoms by questionnaire plus physical and laboratory/imaging findings. Cumulative prevalence rates of UL-WMSDs as at 31 December 2003 reached values of up to 30% in high risk groups. Prevalence rates showed good correlation with the concise OCRA index used for assessment of exposure to repetitive strain and movements of the upper limb. The most frequently occurring disorders were tendon-related cysts and wrist tendonitis. Shoulder disorders were more frequent in male and female leather-cutting operators. This survey showed a significantly high prevalence of UL-WMSDs in sofa industry workers. It did not seem to be confirmed in this study that there was a greater female susceptibility to UL-WMSDs with the exception of carpal tunnel syndrome: gender difference seems to be less relevant at increasing levels of occupational exposure to repetitive movements and exertion of the upper limbs.

This study evaluated the associations between job strain and arginase I in 378 healthy Japanese factory workers by a cross-sectional study measuring nitric oxide (NO)-related parameters (arginase I, L-arginine, exhaled nitric oxide (FeNO), and NOx), clinical parameters, and job strain using a Japanese version of the Job Content Questionnaire by Karasek. Arginase I and FEV1% were negatively correlated with job strain and positively correlated with job control and social support. FeNO and hs-CRP were negatively correlated with job strain. Multiple regression analysis showed negative association of arginase I with job strain and positive association with job control and social support in females. It is concluded that serum levels of arginase I may be useful biomarkers for the diagnosis of job stress in healthy female workers, although many factors can be influencing the data. PMID:28403218

To investigate mortality among workers of an Italian rubber tire factory employed between 1954 and 2008. This cohort study included 6246 men, totaling 190,512 man-years of observation. Employment data were obtained from personnel records, whereas vital status and causes of death were ascertained from local authorities. We computed standardized mortality ratios (SMRs) using national and regional death certification rates. Mortality was significantly lower than expected for all cancers (SMR = 79) and all causes (SMR = 85). The SMRs were 99 for cancer of stomach, 78 for lung, 121 for urinary bladder, 116 for lymphoma, and 89 for leukemia, none being significant. Decreased mortality emerged for cancers of the oral cavity and pharynx (SMR = 45), esophagus (SMR = 29), colorectum (SMR = 71), liver (SMR = 57), and kidney (SMR = 33). This study shows no excess cancer risk among male rubber tire workers employed after 1954.

An analysis of the mortality of a cohort of 6629 workers employed from 1906 to 1981 in a rubber tyre factory in northern Italy (978 deaths and over 133,000 man-years at risk) showed that the all cause mortality ratio was slightly lower than expected (0.91). Overall cancer mortality was close to expected (275 v 259.4) but there were significant excess rates for two cancer sites: pleura (9 observed v 0.8 expected, which may be due to the use of fibre containing talc) and bladder (16 observed v 8.8 expected). Death rates were not raised for other sites previously associated with employment in the rubber industry, such as cancers of the lung and brain, leukaemias, or lymphomas. The substantially reduced relative risk of pleural cancer among workers first employed after 1940 (RR = 0.05 compared with before 1940) probably reflected improvements in working conditions over more recent periods. For cancer of the bladder, the relative risk was also lower for workers first engaged after 1940. Thus no appreciable risk for any disease was apparent for workers employed over the past four decades. Analysis for each of the 27 job categories showed a substantial excess for cancer of the pleura in the mechanical maintenance workers (4 observed v 0.17 expected); an excess of cancer of the lung (21 v 13.48) was also present in this job category.

Migrant workers in low-resource settings may experience multiple types of workplace and security-related stressors. This study explores the relationship between these stressors and adverse mental health outcomes, through a study of migrant workers from Myanmar, working in agriculture, factory, and sex industries in and around Mae Sot, Thailand. Respondent-driven sampling was used to recruit a total sample of 589 male and female migrants. Trained data collectors administered a survey, which included measures of workplace and security-related stressors, and depression and anxiety symptoms. Multivariate regression models were conducted separately for depression and anxiety symptoms. For male agricultural workers, security stressors (β = 1.9, p = .001) are associated with an increase in depression symptoms and coercive working conditions are associated with an increase in anxiety symptoms (β = .8, p = .000). For female agricultural workers, daily hassles and stressors were associated with both depression (β = 1.5, p = .000) and anxiety (β = .5, p = .027), and barriers to exit (β = 3.0, p = .005) and security stressors (β = .9, p = .010) were significantly associated with increased depression symptoms. In the factory subsample, sexual assault and abuse (depression: β = 2.7, p = .009; anxiety: β = 2.8, p = .002) and daily hassles and stressors (depression: β = .7, p = .007; anxiety: β = .7, p = .001) were both significantly associated with increased depression and anxiety symptoms for males. Other categories of stressors similarly showed different associations with mental health outcomes between occupational groups, and between male and female migrant workers. The differing influences of stressors on mental health between the three occupational groups, and between males and females, indicate the need for targeted and tailored approaches to reduce specific stressors and improve services to address mental health needs. Prevention and response need to recognize the differences in working conditions, vulnerabilities, and needs between occupational groups, and between male and female migrant workers.

To estimate the prevalence and identify correlates of anthropometry and clinical risk factors for cardiovascular diseases (CVDs) among ready-made garment (RMG) of workers, majority are females, come from low-socioeconomics conditions. Population-based cross-sectional study with 614 individuals aged ≥18 years were recruited from six different RMG factories. In total, of 313 male (46%) and 301 of female (56%) workers had body mass index (BMI) in the overweight and obese range as per Asian cut off values with corresponding reflection in waist hip ratio (WHR). High proportion of male 84% (95% confidence interval 81-87) had smoking habits. The prevalence of hypertension (HTN), dyslipidemia were 24% vs 15%; 56% vs 43% among males and females respectively. Prevalence of diabetes was 7.3% (5.3-9.4) and pre-diabetes was 10.6% (8.2-13) and it showed female preponderance (4.5% male vs 10.3% female). In multivariable logistic regression HTN showed significant association with age, gender, BMI; glycemic status with age, genderand WHR; dyslipidemia with BMI and WHR. A substantial proportion of RMG workers are at an increased risk of CVDs which need focused attention to reduce smoking (among males) and body-weight and central obesity, particularly in females.

To research the effect of 27.2 MHz radiofrequency radiation on electrocardiograms (ECG), 225 female workers operating radiofrequency machines at a shoe factory were chosen as the exposure group and 100 female workers without exposure from the same factory were selected as the control group. The 6 min electric field strength that the female workers were exposed to was 64.0 ± 25.2 V/m (mean ± SD), which exceeded 61 V/m, the International Commission on Non-Ionizing Radiation Protection reference root mean square levels for occupational exposure. A statistical difference was observed between the exposed group and the control group in terms of the rate of sinus bradycardia (χ(2)  = 11.48, P = 0.003). When several known risk factors for cardiovascular disease were considered, including smoking, age, alcohol ingestion habit, and so on, the exposure duration was not an effective factor for ECG changes, sinus arrhythmia, or sinus bradycardia according to α = 0.05, while P = 0.052 for sinus arrhythmia was very close to 0.05. We did not find any statistical difference in heart rate, duration of the QRS wave (ventricular depolarization), or corrected QT intervals (between the start of the Q wave and end of the T wave) between the exposed and control groups. Occupational exposure to radiofrequency radiation was not found to be a cause of ECG changes after consideration of the confounding factors. Copyright © 2012 Wiley Periodicals, Inc.

Background: Male migrants act as a bridge for transmitting infection from core risk groups to general population and hence this group becomes essential for the HIV control program. Migrant workers constitute a large proportion of workforce in India and HIV/AIDS epidemic in them would cause huge economic losses. Objectives: The aim of this study was to ascertain the HIV-risk behavior among male migrant factory workers. Materials and Methods: This was a cross-sectional facility based survey conducted in 2011. Male migrant workers aged ≥18 years, who were born outside Haryana, who had moved to current location after 15 years of age, who had worked in the current factory for at least one year, who were willing to participate and able to give valid consent were eligible. A consecutive sampling was done. Descriptive, bivariate and multiple logistic regression analyses were done. Results: A total of 755 male subjects completed the interview. About 21.5% had experienced non-spousal sexual intercourse in last one year. Nearly 60% did not use a condom at the last non-spousal sex. Factors associated with recent non-spousal sex were being unmarried, younger age at migration, recent migration to Haryana, greater number of places migrated and lesser total duration of migration and those associated with non-use of condom at the last non-spousal sex were older age, lower education, lesser number of places migrated and lower level of HIV/AIDS knowledge. Conclusion: Unprotected, recent non-spousal sex was common among male migrants, which could increase their HIV/AIDS vulnerability. PMID:25861172

Nocturnal 6-hydroxymelatonin sulfate excretion in female workers exposed to magnetic fields

DOE Office of Scientific and Technical Information (OSTI.GOV)

Juutilainen, J; Stevens, Richard G.; Anderson, Larry E.

The objective of this study was to determine whether daytime occupational exposure to extremely low frequency magnetic fields (MFs) suppresses nocturnal melatonin production. Sixty female volunteers were recruited. Thirty-nine worked in a garment factory, and 21 office workers served as a reference group. Exposure assessment was based on the type of sewing machine used and MF measurements around each type of machine. Eye-level MF flux density was used to classify the operators to higher (> 1 microT) and lower (0.3-1 microT) exposure categories. A third group of factory workers had diverse MF exposures from other sources. The reference group hadmore » average exposure of about 0.15 microT. Urine samples were collected on Friday and Monday for three consecutive weeks. Melatonin production was assessed as urinary 6-hydroxymelatonin sulfate (6-OHMS) excretion. The ratio of Friday morning/Monday morning 6-OHMS was used to test the hypothesis that melatonin production is suppressed after 4 days of occupational MF exposure with significant recovery during the weekend. Possible chronic suppression of melatonin production was evaluated by studying exposure-related differences in the Friday values by multivariate regression analysis. The Monday/Friday ratios were close to 1.0, suggesting that there is no increase in melatonin production over the weekend. The average 6-OHMS excretion on Friday was lower among the factory workers than in the reference group, but no monotonous dose-response was observed. Multivariate regression analysis identified MF exposure, smoking, and age as significant explanatory variables associated with decreased 6-OHMS excretion.« less

Working outside daylight hours (7 am to 7 pm) is called shift work. Shift work is a common practice in many industries and factories such as steel industries, petroleum industries, power plants, and in some services such as medicine and nursing and police forces, in which professionals provide services during day and night. Considering the contradictory reports of different studies, we decided to evaluate the effect of shift work on cholesterol and triglyceride (TG) levels through a historical cohort on steel industry workers. This retrospective cohort study was performed on all the staff of Isfahan's Mobarakeh Steel Company between years 2002 and 2011. There were 5773 participants in this study. Data were collected from the medical records of the staff using the census method. For analysis of data, generalized estimating equation (GEE) regression was used. The results showed a significant difference in cholesterol levels between shift workers and day workers on the first observation (P < 0.001), yet no such difference was observed for TG (P = 0.853). Moreover, the results showed that the variables of age, work experience and BMI were not similar between shift workers and day workers. Therefore, to remove the effect of such variables, we used GEE regression. Despite the borderline difference of cholesterol between regular shift workers and day workers, this correlation was not statistically significant (P = 0.051). The results for TG also showed no correlation with shift work. According to the findings of this study, there is no relationship between shift work and changes in serum TG and cholesterol. The lack of relationship can be due to shift plans for shift workers, nutrition, or the "Healthy Heart project" at Isfahan Mobarakeh Steel Company.

This paper presents a new cognitive assistive technology, nonlinear contextually aware prompting system (N-CAPS) that uses advanced sensing and artificial intelligence to monitor and provide assistance to workers with cognitive disabilities during a factory assembly task. The N-CAPS system was designed through the application of various computer vision and artificial intelligence algorithms that allows the system to track a user during a specific assembly task, and then provide verbal and visual prompts to the worker as needed. A pilot study was completed with the N-CAPS solution in order to investigate whether it was an appropriate intervention. Four participants completed the required assembly task five different times, using the N-CAPS system. The participants completed all of the trials that they attempted with 85.7% of the steps completed without assistance from the job coach. Of the 85.7% of steps completed independently, 32.5% of these were completed in response to prompts given by N-CAPS. Overall system accuracy was 83.3%, the overall sensitivity was 86.2% and the overall specificity was 82.4%. The results from the study were positive in that they showed that this type of technology does have merit with this population. Implications for Rehabilitation It provides a concise summary of the importance of work in the lives of people with intellectual disabilities and how technology can support this life goal. It describes the first artificially intelligent system designed to support workers with intellectually disabilities. It provides evidence that individuals with intellectual disabilities can perform a work task in response to technology.

Contact Eczema Caused by True Teak (Tectona Grandis)

An epidemiological study of occupational contact eczema in a furniture factory is presented. The localization, distribution, and clinical features of the skin lesions were characteristic of contact eczema caused by a sensitizing or irritating dust. True teak—Tectona grandis—was the cause of the skin condition. That teak is a fairly potent sensitizer and also contains primary irritants is fully confirmed by the present study. About half the employees who were heavily exposed to teak dust suffered from eczema and/or severe itching. Only 8% of those with slight exposure to teak dust experienced skin symptoms. Patch tests with native teak dust moistened with water were applied on 10 “controls” and 112 workers who were exposed to teak in various working procedures. Moistened teak dust produced toxic reactions in 20·5%, while native teak dust did not have primary irritant effects and was, therefore, considered to be the substance of choice for patch testing; 18·7% of the workers showed an allergic skin reaction to native teak dust. The diagnosis of allergic contact eczema was made in 12·5%, and 6·2% were considered to have latent allergy. Primary irritant (contact) eczema was considered to be present in four individuals who had experienced acute, transitory, eczematous eruptions during the hot part of the summer when they perspired freely. In these cases the patch test to native teak dust was negative. Desensitization or “hardening” was observed in four workers. In most cases the skin lesions were not severe enough to cause sickness absence. The cause of the relatively high percentage of sensitization to teak among the workers in the factory is discussed. The importance of suitable prophylactic measures is stressed. PMID:14459786

Health effects of occupational exposure to lead were investigated among 92 exposed workers in lead-acid battery factory and 40 nonexposed workers serving as a control group from an oil mill in Khartoum North industrial area. The two groups were closely similar in age, stature, body weight, and socioeconomic conditions. A highly significant increase (P<.01) was recorded in blood lead, urinary coproporphyrin, and basophilic stippled red blood cells of the exposed group in comparison to the control group. Central nervous system symptoms (insomnia, fatigue, weakness, and drowsiness) were reported by 50% and other symptoms such as abdominal colic and constipation weremore » reported by 41% of the exposed group. Blue line on the gum was detected only on 2% of the exposed group. Strong associations between exposure to lead and the prevalence of central nervous system symptoms, abdominal colic, and constipation were recorded. Exposure to exceedingly high levels of lead in the working environment causes adverse health effects.« less

The objective of this study was to assess factors affecting lung function among 685 workers in the rubberwood (Hevea brasiliensis) furniture industry in the Chonburi and Rayung provinces of eastern Thailand. Study data were gathered using questionnaires, by sampling wood dust, and by spirometry. The mean wood dust exposure level in the factories was 4.08 mg/m3 (SD = 1.42, range: 1.15-11.17 mg/m3). The mean overall percent of predicted forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and FEV1/FVC values were 84 % (SD = 13.41), 86 % (SD = 14.40), and 99% (SD = 10.42), respectively. Significant negative correlations were found between mean dust exposure levels and FVC (p = 0.0008), and FEV1/FVC% (p < 0.001), but not FEV1 (p = 0.074). An association between decline in lung function and wood dust levels among wood workers suggests that rubberwood dust exposure negatively affects lung function.

The study aimed to conduct an ergonomic intervention on a conventional line (CL) in a semiconductor factory in Malaysia, an industrially developing country (IDC), to improve workers' occupational health and safety (OHS). Low-cost and simple (LCS) ergonomics methods were used (suitable for IDCs), e.g., subjective assessment, direct observation, use of archival data and assessment of noise. It was found that workers were facing noise irritation, neck and back pains and headache in the various processes in the CL. LCS ergonomic interventions to rectify the problems included installing noise insulating covers, providing earplugs, installing elevated platforms, slanting visual display terminals and installing extra exhaust fans. The interventions cost less than 3 000 USD but they significantly improved workers' OHS, which directly correlated with an improvement in working conditions and job satisfaction. The findings are useful in solving OHS problems in electronics industries in IDCs as they share similar manufacturing processes, problems and limitations.

ABSTRACT Spontaneous abortions in hospitals were analysed from two sources—membership files of the Union of Rubber and Leather Workers (about 10 000 women) and records of the personnel of a rubber factory (about 1600 women). Two frequencies of spontaneous abortions were calculated for each population analysed: rate (No spontaneous abortions X 100/No pregnancies) and ratio (No spontaneous abortions X 100/No births). The two frequencies were increased for all union members compared with all Finnish women. The frequencies, however, did not appreciably differ when the pregnancies occurred during union membership as compared with the pregnancies before or after membership. The frequency of spontaneous abortions was higher for the short-time union members than for those employed for longer periods, but the increased frequency did not correlate with union membership. The employees of a rubber factory had slightly fewer spontaneous abortions on average than the community population. The women employed in the rubber factory for three to 23 months were found to have appreciably higher frequencies of spontaneous abortions than the women employed for longer periods. The present study showed the feasibility of using cases of spontaneous abortions in hospitals in an occupational study with longitudinal employment data. Women with short periods of employment appeared to have more spontaneous abortions than those with longer periods of employment suggesting the presence of selection mechanisms, perhaps with some analogies to the “healthy worker effect” in occupational mortality studies. The presence of such selection mechanisms deserve serious consideration in occupational reproductive epidemiology. PMID:6824605

Assess the exposure to volatile organic compounds (VOCs)in furniture handicraft factories workers in two populations of Sucre (Sincelejo and Sampués), North of Colombia.Identify possible signs and/or symptoms related to exposure to these contaminants. This was an analytical cross sectional study (2011), using a questionnaire. Study population consisted of 66 individuals, 41 exposed and 25 controls. Personal samples were collected for concentration quantifying of benzene, toluene, ethylbenzene and xylenes (both groups) and contrasting them with health effects possible attributed to these contaminants. The concentrations of benzene, toluene and m/p-xylene were higher in the exposed group (9.5 mg/m(3), 8.1 mg/m(3) and 12.1 mg/m(3))compared with the control group (0.2 mg/m(3), 0.3 mg/m(3) and 0.03 mg/m(3)). Muscular pain 82.9 % (PR=3.8; CI95%:1.2-11.8) and somnolence 65.9 % (PR=4.9; CI95%:1.7-14.7)were associated with a higher exposure.Factor such as mixtures of solvents (thinner) in the work and vehicles' traffic can contribute to these results. Several sources contribute to increases personal exposure of VOCs in furniture handicraft factories workers North of Colombia. Additionally, excessive use of these compounds may be generating adverse effects on the health of workers.

Isocyanates are one of the most commonly reported causes of occupational asthma; however, the risks of developing isocyanate asthma in modern production facilities remain poorly defined. We evaluated TDI exposure and respiratory health among an inception cohort of workers during their first year of employment at a new polyurethane foam production factory. Forty-nine newly hired workers were evaluated pre-employment, 6-months, and 12-months post-employment through questionnaire, spirometry, and TDI-specific serology. Airborne TDI levels were monitored by fixed-point air sampling and limited personal sampling. Qualitative surface SWYPE™ tests were performed to evaluate potential sources of skin exposure. Airborne TDI levels overall were low; over 90% of fixed-point air measurements were below the limit of detection (0.1 ppb). Over the first year of employment, 12 of the 49 original workers (24.5%) were lost to follow-up, no additional workers were enrolled, and seven of the 49 original workers (14.2%) developed either new asthma symptoms (N = 3), TDI-specific IgG (N = 1), new airflow obstruction (N = 1) and/or a decline in FEV1  ≥ 15% (N = 3), findings that could indicate TDI-related health effects. The prevalence of current asthma symptoms was significantly higher in the workers lost to follow-up compared to those who completed the 12-month follow-up (25% vs. 2.7%; P = 0.04). The findings suggest possible early TDI-related health effects in a modern polyurethane production plant. These findings also highlight the need for further longitudinal evaluation of these workers and the challenges of studying workers at risk for isocyanate asthma. © 2014 Wiley Periodicals, Inc.

Background: Mental health disorders affect around 500 million people worldwide. In India, around 10–12% of people are affected by a mental disorder either due to stress, depression, anxiety, or any other cause. Mental health of workers affects the productivity of the workplace, with estimates putting these losses to be over 100 million dollars annually. Aims: The study aims to measure depression, anxiety, and stress levels of workers in an industry and to investigate if it has any effect on productivity of the firm. Materials and Methods: The study utilized a cross-sectional design and was conducted among workmen of the firm. A sociodemographic based questionnaire and a mental health screening tool -Depression Anxiety Stress Scale (DASS)-21 were used for the same. A total of 90 completed questionnaires were analyzed for the study. The data was analyzed for central tendencies as well as for any associations and correlations. Results: The study showed that none of the workers had a positive score for depression. It also showed that around 36% of the workers had a positive score for anxiety and 18% of the workers had a positive score for stress on DASS-21 scale. The odds ratio between stress and number of leaves taken by a worker in the last 3 months suggested a dose–response relationship, but was statistically insignificant. Conclusion: The study found a prevalence rate of around 18–36% for anxiety and stress amongst the workers at the factory. Large-scale studies will help understand the effect mental health status has on the Indian workplace. PMID:26257479

Contemporary mushroom factories are places where there is a substantial risk of the occurrence of respiratory allergy. The aims of this investigation were to estimate its causative agents and to evaluate the contribution of innate immune response in mushroom workers who cultivate Hypsizigus marmoreus (Bunashimeji). Cross-sectional and follow-up studies were performed in the factory. We investigated CD1b, CD3, CD4, CD8, CD14, CD45RO, CD62L and CD161 expression in peripheral blood mononuclear cells (PBMC) by flow cytometry, and serum levels of interleukin (IL-2), IL-4, granulocyte-macrophage colony stimulating factor (GM-CSF), IL-13 and interferon (IFN)-γ by enzyme-linked immunosorbent assay (ELISA). Co-culture experiments of PBMC with spore extracts were also performed. Percentages of CD1b+ monocytes, natural killer (NK), NK T and CD4+ T cells were increased in the workers compared with controls. Increases in Th2 type cells, Th2/Th1 ratio and serum IL-13 and decreased IFN-γ were detected, indicating a Th2-biased status of the workers. The follow-up study showed that monocytes and NK cells increased soon after employment while CD4+ T, Th2 and NK T cells increased gradually as employment time lengthened. Serum precipitating antibody to the mushroom antigen could be detected at a later stage. Co-cultivation of PBMC with the spore extracts induced much higher CD1b expression, and suppressed secretion of Th1 cytokine in culture supernatants. These results indicate that the mushroom antigen contains highly immunogenic substances which stimulate PBMC into a Th2-biased in vivo status, and innate immune cells might also play a critical role in developing respiratory allergy in mushroom workers.

With the advent of the deep economic crisis in Argentina on 2001, the recovery of companies through to the creation of the Cooperatives Working Self-Management or Factories Recovered by its workers was constituted as one of the ways in which the salaried disobeyed the increasing unemployment. When the companies turn into recovered factories they tend to leave of side practices that have been seen like imposed by the previous organization and not understanding them as a primary condition for the execution of his tasks. Safety and ergonomics are two disciplines that are no longer considered relevant to the daily work. Therefore this investigation aims to revalue, undergo semantic to give back to a place in every organization analyzed. This research developed a self-diagnostic tool for working conditions, and the environment, present in the recovered factories.

In this article, I use a new book about Jean Piaget to introduce a new historical method: examining "psychological factories." I also discuss some of the ways that "Great Men" are presented in the literature, as well as opportunities for new projects if one approaches the history of the discipline differently and examines the conditions that made that greatness possible. To that end, the article includes many details about Piaget that have never before been discussed in English. Attention is drawn, in particular, to Piaget's collaborators: the hundreds of workers at his factory in Geneva, many of whom were women. (PsycINFO Database Record (c) 2012 APA, all rights reserved).

In urban China, more single women are becoming pregnant and resorting to induced abortion, despite the wide availability of temporary methods of contraception. We developed and piloted a workplace-based intervention to promote contraceptive use in unmarried female migrants working in privately owned factories. Quasi-experimental design. In consultation with clients, we developed a workplace based intervention to promote contraception use in unmarried female migrants in a privately owned factory. We then implemented this in one factory, using a controlled before-and-after design. The intervention included lectures, bespoke information leaflets, and support to the factory doctors in providing a contraceptive service. 598 women participated: most were under 25, migrants to the city, with high school education. Twenty percent were lost when staff were made redundant, and implementation was logistically complicated. All women attended the initial lecture, and just over half the second lecture. Most reported reading the educational material provided (73%), but very few women reported using the free family planning services offered at the factory clinic (5%) or the Family Planning Institute (3%). At baseline, 90% (N = 539) stated that contraceptives were required if having sex before marriage; of those reporting sex in the last three months, the majority reporting using contraceptives (78%, 62/79) but condom use was low (44%, 35/79). Qualitative data showed that the reading material seemed to be popular and young women expressed a need for more specific reproductive health information, particularly on HIV/AIDS. Women wanted services with some privacy and anonymity, and views on the factory service were mixed. Implementing a complex intervention with a hard to reach population through a factory in China, using a quasi-experimental design, is not easy. Further research should focus on the specific needs and service preferences of this population and these should be considered in any policy reform so that contraceptive use may be encouraged among young urban migrant workers.

Shift work (SW) can affect worker health and productivity. Working at night, workers often accumulate fatigue and are less productive. In Brazil, laws have been drafted aiming to reduce night work and rotating shift hours. In order to slash costs, companies have been looking for new arrangements to improve productivity under these conditions. The purpose of this study was to examine management changes and their outcomes in a large glass factory located in an industrial region of Brazil. The results show that the management, seeking equal productivity among shifts, focused its efforts mainly on distributing employee expertise. The arrangement resulted in 12 different groups that combine to serve three fixed shifts. A same shift can be served by more than one group, and the members of a same group share days off on different days. There was no statistically significant productivity difference among the three shifts. The on-site examination showed that part of the production was held by the workers and transferred to the next shift in order for them to be able to meet the management's performance rate requirements. The finding shows how a Brazilian cultural trait (resistance without conflict) is used to drive coping in SW.

We assessed the exposure of semiconductor workers to extremely low frequency-magnetic fields (ELF-MF) and identified job characteristics affecting ELF-MF exposure. These were demonstrated by assessing the exposure of 117 workers involved in wafer fabrication (fab) and chip packaging wearing personal dosimeters for a full shift. A portable device was used to monitor ELF-MF in high temporal resolution. All measurements were categorized by operation, job and working activity during working time. ELF-MF exposure of workers were classified based on the quartiles of ELF-MF distribution. The average levels of ELF-MF exposure were 0.56 µT for fab workers, 0.59 µT for chip packaging workers and 0.89 µT for electrical engineers, respectively. Exposure to ELF-MF differed among types of factory, operation, job and activity. Workers engaged in the diffusion and chip testing activities showed the highest ELF-MF exposure. The ELF-MF exposures of process operators were found to be higher than those of maintenance engineers, although peak exposure and/or patterns varied. The groups with the highest quartile ELF-MF exposure level are operators in diffusion, ion implantation, module and testing operations, and maintenance engineers in diffusion, module and testing operations. In conclusion, ELF-MF exposure among workers can be substantially affected by the type of operation and job, and the activity or location. PMID:29614730

We investigated the effects of 12-hour shift work for five to seven consecutive days and overtime on the prevalence of severe sleepiness in the automobile industry in Korea. [Correction added after online publication 28 Nov: Opening sentence of the summary has been rephrased for better clarity.] A total of 288 randomly selected male workers from two automobile factories were selected and investigated using questionnaires and sleep-wake diaries in South Korea. The prevalence of severe sleepiness at work [i.e. Karolinska Sleepiness Scale (KSS) score of 7 or higher] was modeled using marginal logistic regression and included theoretical risk factors related to working hours and potential confounding factors related to socio-economic status, work demands, and health behaviors. Factors related to working hours increased the risk for severe sleepiness at the end of the shift in the following order: the night shift [odds ratio (OR): 4.7; 95% confidence interval (CI): 3.6-6.0)], daily overtime (OR: 2.2; 95% CI: 1.7-2.9), weekly overtime (OR: 1.6; 95% CI: 1.0-2.6), and night overtime (OR: 1.6; 95% CI: 0.8-3.0). Long working hours and shift work had a significant interactive effect for severe sleepiness at work. Night shift workers who worked for 12 h or more a day were exposed to a risk of severe sleepiness that was 7.5 times greater than day shift workers who worked less than 11 h. Night shifts and long working hours were the main risk factors for severe sleepiness among automobile factory workers in Korea. Night shifts and long working hours have a high degree of interactive effects resulting in severe sleepiness at work, which highlight the need for immediate measures to address these characteristics among South Korean labor force patterns.

Factors related to overweight were examined in a cross-sectional survey that included 1612 women workers from 10 large electronics assembly factories in Peninsular Malaysia. Respondents were Malaysian citizens, direct production workers below the supervisory level, and had worked at least a year in the factory where they were presently employed. Heights and weights were taken to calculate the body mass index (BMI). Weights and BMI increased with increasing age. After adjusting for age, odds ratios for overweight were significantly raised for married women in relation to not married women (OR 1.5, 95% CI=1.15-2.02), lower secondary education in relation to higher than upper secondary education (OR 1.8, 95% CI=1.06-3.14), monthly income RM800-999 (OR 1.7, 95% CI=1.21-2.45) and >/=RM1,000 (OR 1.8, 95% CI=1.23-2.72) in relation to

Few studies have examined the incidence of malignant mesothelioma (MM) associated with distinct sources of asbestos exposure (occupational, familial, or environmental). We assessed the impact of asbestos exposure-global and by source-on the incidence of MM in Broni, an Italian town in which an asbestos cement factory once operated (1932-1993). Based on data collected by the Lombardy Mesothelioma Registry, we calculated the number of observed and expected MM cases among workers, their cohabitants, and people living in the area in 2000-2011. We identified 147 MM cases (17.45 expected), 138 pleural and nine peritoneal, attributable to exposure to asbestos from the factory. Thirty-eight cases had past occupational exposure at the factory (2.33 expected), numbering 32 men (26 pleural, six peritoneal) and six women (four pleural, two peritoneal). In the families of the workers, there were 37 MM cases (4.23 expected), numbering five men (all pleural) and 32 women (31 pleural, one peritoneal). Among residents in Broni or in the adjacent/surrounding towns, there were 72 cases of pleural MM (10.89 expected), numbering 23 men and 49 women. The largest MM excess was found in the towns of Broni (48 observed, 3.68 expected) and Stradella (16 observed, 1.85 expected). This study documents the large impact of the asbestos cement factory, with about 130 excess MM cases in a 12-year period. The largest MM burden was among women, from non-occupational exposure. Almost half of the MM cases were attributable to environmental exposure. Copyright © 2014 Elsevier Ltd. All rights reserved.

To analyze the relationship between joint of heat and noise, and metabolic syndrome in a steel rolling factory workers. A total of 590 steel workers were selected as subjects by cluster sampling method from workers of a steel factory. They were investigated by face to face way with the unified questionnaire which contents included personal information, occupational history, personal history, habits and other factors. Furthermore, height, weight, waist circumference and blood pressure were measured. Referring to the 2005 International Diabetes Federation (IDF) issued by the metabolic syndrome (MS) worldwide uniform definition combines waist diagnosis MS. A database was built by Epidata 3.0 software, and data was analyzed by SPSS 17.0. 571 steel workers were from 22 to 60 years, mean age (41.2 -7.9) years old. The prevalence of metabolic syndrome in steel workers was 17.9%. The prevalence of metabolic syndrome of those who exposed to high temperature was 18.8%, higher than that of those who did not expose to high temperature (5.3%), there was a statistically significant difference (P < 0.05). The prevalence of metabolic syndrome of those who exposed to noise was 20.6%, higher than that of those who did not exposed to noise (14.0%) (P < 0.05). After adjusting for the effects of confounding factors, the prevalence of MS those who exposed to high temperatures and noise is 1.118 times as high as that of those who did not exposed to high temperatures and noise. The combined effects of heat and noise is related to the increasing prevalence of MS of steel workers.

Background. Cement dust inhalation is associated with deleterious health effects. The impact of cement dust exposure on the peak expiratory flow rate (PEFR), liver function, and some serum elements in workers and residents near cement factory were assessed. Methods. Two hundred and ten subjects (50 workers, 60 residents, and 100 controls) aged 18–60 years were studied. PEFR, liver function {aspartate and alanine transaminases (AST and ALT) and total and conjugated bilirubin (TB and CB)}, and serum elements {lead (Pb), copper (Cu), manganese (Mn), iron (Fe), cadmium (Cd), selenium (Se), chromium (Cr), zinc (Zn), and arsenic (As)} were determined using peak flow meter, colorimetry, and atomic absorption spectrometry, respectively. Data were analysed using ANOVA and correlation at p = 0.05. Results. The ALT, TB, CB, Pb, As, Cd, Cr, Se, Mn, and Cu were significantly higher and PEFR, Fe, and Zn lower in workers and residents compared to controls (p < 0.05). Higher levels of ALT, AST, and Fe and lower levels of Pb, Cd, Cr, Se, Mn, and Cu were seen in cement workers compared to residents (p < 0.05). Negative correlation was observed between duration of exposure and PEFR (r = −0.416, p = 0.016) in cement workers. Conclusions. Cement dust inhalation may be associated with alterations in serum elements levels and lung and liver functions while long term exposure lowers peak expiratory flow rate. PMID:26981118

The risk of musculoskeletal disorders for workers due to repetitive movements during tomato harvesting.

PubMed

Cecchini, M; Colantoni, A; Massantini, R; Monarca, D

2010-04-01

Tomatoes are the most common crop in Italy. The production cycle requires operations in the field and factory that can cause musculoskeletal disorders due to the repetitive movements of the upper limbs of the workers employed in the sorting phase. This research aims to evaluate these risks using the OCRA (occupational repetitive actions) index method This method is based firstly on the calculation of a maximum number of recommended actions, related to the way the operation is performed, and secondly on a comparison of the number of actions effectively carried out by the upper limb with the recommended calculated value. The results of the risk evaluation for workers who manually sort tomatoes during harvest showed a risk for the workers, with an exposure index greater than 20; the OCRA index defines an index higher than 3.5 as unacceptable. The present trend of replacing manual sorting onboard a vehicle with optical sorters seems to be appropriate to reduce the risk of work-related musculoskeletal disorders (WMSDs) and is supported from both a financial point of view and as a quality control measure.

Welding is a major industrial process used for joining metals. Occupational exposure to welding fumes is a serious occupational health problem all over the world. The degree of risk to welder's health from fumes depends on composition, concentration, and the length of exposure. The aim of this study was to investigate workers' welding fume exposure levels in some industries in Jeddah, Saudi Arabia. In each factory, the air in the breathing zone within 0.5 m from welders was sampled during 8-hour shifts. Total particulates, manganese, copper, and molybdenum concentrations of welding fumes were determined. Mean values of eight-hour average particulate concentrations measured during welding at the welders breathing zone were 6.3 mg/m(3) (Factory 1), 5.3 mg/m(3) (Factory 2), 11.3 mg/m(3) (Factory 3), 6.8 mg/m(3) (Factory 4), 4.7 mg/m(3) (Factory 5), and 3.0 mg/m(3) (Factory 6). Mean values of airborne manganese, copper, and molybdenum levels measured during welding were in the range of 0.010 mg/m(3)-0.477 mg/m(3), 0.001 mg/m(3)-0.080 mg/m(3) and 0.001 mg/m(3)-0.058 mg/m(3) respectively. Mean values of calculated equivalent exposure values were: 1.50 (Factory 1), 1.56 (Factory 2), 5.14 (Factory 3), 2.21 (Factory 4), 2.89 (Factory 5), and 1.20 (Factory 6). The welders in factories 1, 2, 3, and 4 were exposed to welding fume concentration above the SASO limit value, which may increase the risk of respiratory health problems.

The prevailing symptoms among the approximately 60 affected predominantly female employees, was nausea. Environmental evaluation revealed that a potential hazard exists to employees from exposure to nickel and cadmium dusts. Workers in 4 departments showed levels of cadmium and nickel in hair and urine above those found in the control group; workers in 2 of the 4more » departments also showed excessive symptomatology and physical findings indicating upper respiratory irritation. Air samples also showed some excessive levels of cadmium and nickel particularly in these same 2 departments. However, medical evaluation of employees failed to demonstrate any apparent serious occupationally induced illness.« less

Why do workers behave unsafely at work? Determinants of safe work practices in industrial workers.

To explore the relation between safety climate (workers' perceptions regarding management's attitudes towards occupational safety and health) and workers' behaviour at work. Cross sectional survey of workers at the pottery industry in Castellon, Spain. Sampling was stratified by plant size and workers' gender, according to data on the working population at this setting. A total of 734 production workers were interviewed. Information was collected on safety climate and workers' behaviour towards occupational risks with a specific questionnaire. A safety climate index (SCI, scale 0-100) was constructed adding scores for each item measuring safety climate in the questionnaire. Workers' unsafe behaviour was analysed for the different safety climate index levels. Mean score for SCI was 71.90 (SD 19.19). There were no differences in SCI scores according to age, gender, education, children at charge, seniority at work, or type of employment. Small workplaces (<50 workers) showed significantly worse SCI (mean 67.23, SD 19.73) than the largest factories (>200 workers). Lower levels of SCI (SCI <50) were related to workers' unsafe behaviours (full/high accord with the statement "I excessively expose myself to hazards in my work", adjusted odds ratio ORa 2.79, 95% CI 1.60 to 4.88), and to lack of compliance with safety rules (ORa 12.83, 95% CI 5.92 to 27.80). Safety climate measures workers' perception of organisational factors related to occupational health and safety (for example, management commitment to risk prevention or priorities of safety versus production). In this study these factors are strongly associated with workers' attitudes towards safety at work. Longitudinal studies can further clarify the relation between safety climate and workers' behaviour regarding occupational safety and health.

Improving productivity levels: family planning services for factory workers.

In May 1984, the Minister of Manpower in Indonesia, the Chairman of the BKKBN, and representatives of the employers' and workers' organizations of Indonesia issued a joint decree pledging that they would work together to enhance the implementation of the family planning program among workers in the organized sector. 1 objective of the decree is to improve workers' productivity and the standard of living of workers and their families by implementing a family planning program. 1 baseline survey and a clinic-based survey in 5 provinces revealed that 90% of women workers are between 21-40, or are of reproductive age, and are sexually active. Only about 50% are practicing family planning; the other 50% are afraid to practice family planning due to potential side effects of various methods. This fear was most often caused by negative rumors spread by unsatisfied family planning clients. Placing materials for family planning promotion such as instructional posters and video programs advertising contraceptive services in the work setting may increase knowledge and help alleviate some of this fear. Other studies of family planning services show that employees prefer female medical doctors or midwives as service providers, employees are willing to pay for services (but can only afford a small fee), and family planning service points should be near employees' work sites.

Rescue workers and trauma: Assessing interaction among risk factors after a firework factory explosion.

PubMed

Romano, Eugenia; Elklit, Ask

This study investigates which factors had the biggest impact on developing distress in rescue workers who were involved in a firework factory explosion. Four hundred sixty-five rescuers were assessed using items investigating demographic factors, organizational variables, social support, personality variables, and distress symptoms. Correlation and regression analyses were performed. Our final model provided 70 percent of the predictive model for post-traumatic stress disorder (PTSD) severity. Waiting time, lack of rest, problems at work, and perceived level of danger seemed to have the highest impact on protective factors. In addition to perceived life danger and personality, small organizational factors seem to play an important role in the prediction of PTSD. The importance of such factors needs further investigation in future research, contributing to a better organization in the field of disaster management.

A pilot hazardous airborne carbonyls study was carried out in Hong Kong and the Mainland of China. Workplace air samples in 14 factories of various types of manufacturing and industrial operations were collected and analyzed for a panel of 21 carbonyl compounds. The factories can be classified into five general categories, including food processing, electroplating, textile dyeing, chemical manufacturer, and petroleum refinery. Formaldehyde was invariably the most abundant carbonyl compound among all the workplace air samples, accounting for 22.0-44.0% of the total measured amount of carbonyls on a molar basis. Acetone was also found to be an abundant carbonyl in workplace settings; among the selected industrial sectors, chemical manufacturers' workplaces had the highest percentage (an average of 42.6%) of acetone in the total amount of carbonyls measured in air. Benzaldehyde accounted for an average of 20.5% of the total amount of detected carbonyls in electroplating factories, but its contribution was minor in other industrial workplaces. Long-chain aliphatic carbonyls (C6-C10) accounted for a large portion (37.2%) of the total carbonyls in food-processing factories. Glyoxal and methylglyoxal existed at variable levels in the selected workplaces, ranging from 0.2% to 5.5%. The mixing ratio of formaldehyde ranged from 8.6 to 101.2 ppbv in the sampled workplaces. The observed amount of formaldehyde in two paint and wax manufacturers and food-processing factories exceeded the World Health Organization (WHO) air quality guideline of 81.8 ppbv. Carcinogenic risks of chronic exposure to formaldehyde and acetaldehyde by the workers were evaluated. The lifetime cancer hazard risks associated with formaldehyde exposure to male and female workers ranged from 2.01 x 10(-5) to 2.37 x 10(-4) and 2.68 x 10(-5) to 3.16 x 10(-4), respectively. Such elevated risk values suggest that the negative health impact of formaldehyde exposure represents a valid concern, and proper actions should be taken to protect workers from such risks. Many carbonyl species (e.g., formaldehyde, acetaldehyde, and acrolein) are air toxins and they pose public healt risks. The scope of this investigation covers 21 types of carbonyls based on samples collected from 14 different workplaces. Findings of the study will not only provide a comprehensive assessment of indoor air quality with regard to workers' healthy and safety, but also establish a theoretical foundation for future formulation of intervention strategies to reduce occupational carbonyl exposures. No similar study has been carried out either in Hong Kong or the Mainland of China.

Metabolic syndrome (MetS) is a major health risk in Thailand. Although it is reported that females have a higher rate of MetS than males, very few peer-led intervention studies have been conducted on specific groups, such as seamstresses, at risk of MetS. This study aimed to evaluate the effect of a peer-led intervention program on reducing MetS risk factors in individuals working in Thai Uniform Sewing Military Factories. A quasiexperimental program was introduced using a pre- and posttest design that was applied to female sewing factory workers selected for this research. All participants had at least one of the key MetS symptoms. The experimental group (N=50 participants) received 12 weekly peer-led individual support discussion sessions that included both dietary and physical activity (PA) advice and the control group (N=50 participants) followed their usual daily routines. The Student's t -test and the Pearson's chi-squared test were used to compare the differences of baseline data and analysis of variance was used for analysis of the data after intervention. The results showed that after 3 months of participation, when compared to the control group, the experimental group had significantly improved systolic blood pressure (BP) ( P =0.04), diastolic BP ( P <0.001), PA ( P =0.05), knowledge scores of MetS, perception of MetS and risk factors ( P <0.001), and stress assessment ( P =0.002). Waist circumference, body mass index, and Food Frequency Questionnaire score were not significantly different but still improved. Findings from this study suggest that a peer-led support program can be introduced as an effective means of improving the behaviors of mostly sedentary factory workers at risk of MetS caused by working habits that are detrimental to health.

Concentrations and length distributions of uncoated and coated amphibole fibres in the lungs of 27 workers at the Leyland, Nottingham, and Blackburn gas-mask factories were measured after death with the light microscope using the membrane filter technique. Measurements were also made on a worker exposed to crocidolite at the Chemical Defence Experimental Establishment, Porton, and on three miners from the Wittenoom mine in Western Australia where the crocidolite used in the manufacture of military respirators is reputed to have originated. In selected cases, fibre concentrations and dimensions were also measured with the electron microscope. All but two subjects died with a mesothelial tumour. Fibre concentrations ranged from 7 x 10(4) to almost 10(9) fibres/g dry weight. There appeared to be no relation between latent period and fibre concentration. The significance of the wide range of fibre concentrations which was associated with the development of mesothelial tumours is discussed and also the relation between the relative frequency and dimensions of uncoated and coated fibres.

2000-01-01

A cross sectional study was carried out to evaluate the extent of occupational health problems focusing on some aspects of musculoskeletal symptoms among batik workers in Kelantan, Malaysia. The workers selected must have been in that industry for at least one year. Using cluster sampling, 202 workers were selected from 21 factories. More than half (60.2%) of the workers had been troubled with musculoskeletal symptoms at work. The most common symptoms were pain over the shoulders (41.0%), lower back (34.4%) and ankle (34.4%). Duration of employment, younger age group, prolonged standing and awkward working task were among contributing factors. It is therefore necessary to improve on both ergonomic and psychosocial environments of batik workers in order to prevent these musculoskeletal symptoms. PMID:22977385

To guide the development of targeted interventions for the prevention of work-related back pain, this manuscript estimates the prevalence of back pain and its association with a variety of risk factors among Almeda textile factory production works from March to April 2015. An institutional-based cross-sectional study was carried out in Almeda textile factory, North Ethiopia. Randomly selected workers were administered a structured questionnaire about their socio-economic status, lifestyle, working conditions, back pain and selected risk factors. The data was entered to Epi Info 3.5.4 version and analyzed using SPSS version 16. Descriptive statistics were done to characterize the study participants. Bivariate and multiple logistic regressions were fitted to control confounding variables. Adjusted odds ratio with 95% confidence intervals was computed. The prevalence of work-related musculoskeletal disorders was 53.1%. Gender, age, years of service, lack of physical activity, unavailability of adjustable chair, work-load and poor light were significantly associated with increased risk of back pain. The high prevalence of work-related back pain disorder implies that; habit of doing physical exercise, availing adjustable chair and light at the working place, are key issues which require specific interventions.

A right to live: girl workers in the Bangladeshi garment industry.

PubMed

Wahra, G N; Rahman, F

1995-06-01

According to a survey conducted in 1989, there are 772 approved and registered garment factories in Bangladesh. These factories employ approximately 300,000 individuals, 90% of whom are women. A more recent estimate in a Bangladeshi newspaper, however, posits that up to five million people are directly or indirectly dependent upon the garment industry. Many of the women who work in Bangladesh's garment factories are under age 15 years. In some countries, such as the US, the employment of such young individuals constitutes a violation of child labor laws. Therefore, under the Harkin Bill, the US will no longer import garments produced by children younger than age 15 years. Many garment workers under age 15 years have already been put out of work or will soon be terminated. The authors explain that while the intent of the Harkin Bill may be to protect children, it is difficult to adopt the moral high ground in a poor country like Bangladesh. Regardless of one's age in Bangladesh, having a job may be the only way to survive. No job often means no food or shelter. The authors discuss women in the garment industry, one girl's case, alternative employment opportunities, and the future.

To compare the usefulness of determining unchanged forms of volatile organic compounds (VOCs), namely toluene (TOL), ethylbenzene (EB) and xylene (XYL), in urine with the effectiveness of the already used biomarkers of occupational exposure. Surveys were conducted in two workplaces (paint factory and footwear factory). In total, 65 subjects participated in the study. Air samples were collected using individual samplers during work shift. Urine and blood samples were collected at the end of work shift. Urine samples were analyzed for unchanged compounds and selected metabolites, while blood samples were tested for unchanged compounds. VOCs in blood and urine were determined by solid phase microextraction gas chromatography (SPME-GC-MS). In the paint factory, the geometric mean (GM) concentrations of VOCs in the air ranged as follows: 0.2-4.7 mg/m(3) for TOL, 0.4-40.9 mg/m(3) for EB and 0.1-122.6 mg/m(3) for XYL. In the footwear factory, the GM concentration of TOL in the air amounted to 105.4 mg/m(3). A significant correlation (p < 0.05) was observed between VOCs in blood, urine and air. The regression analyses performed for paint factory workers showed that TOL-U and TOL-B were better biomarkers of exposure (r = 0.72 and r = 0.81) than benzoic acid (r = 0.12) or o-cresol (r = 0.55). The findings of the study point out that the concentration of unchanged VOCs in urine can be a reliable biological indicator of low level occupational exposure to these compounds.

Dental erosion, and specifically its symptoms, has long been studied in Japan as an occupational dental disease. However, in recent years, few studies have investigated the development of this disease or labor hygiene management aimed at its prevention. As a result, interest in dental erosion is comparatively low, even among dental professionals. Our investigation at a lead storage battery factory in 1991 found that the work environmental sulfuric acid density was above the tolerable range (1.0mg/m(3)) and that longterm workers had dental erosion. Therefore, workers handling sulfuric acid were given an oral examination and rates of dental erosion by tooth type, rates of erosion by number of working years and rates of erosion by sulfuric acid density in the work environment investigated. Where dental erosion was diagnosed, degree of erosion was identified according to a diagnostic criterion. No development of dental erosion was detected in the maxillary teeth, and erosion was concentrated in the anterior mandibular teeth. Its prevalence was as high as 20%. Rates of dental erosion rose precipitously after 10 working years. The percentages of workers with dental erosion were 42.9% for 10-14 years, 57.1% for 15-19 years and 66.7% for over 20 years with 22.5% for total number of workers. The percentages of workers with dental erosion rose in proportion to work environmental sulfuric acid density: 17.9% at 0.5-1.0, 25.0% at 1.0-4.0 and 50.0% at 4.0-8.0mg/m(3). This suggests that it is necessary to evaluate not only years of exposure to sulfuric acid but also sulfuric acid density in the air in factory workers.

Physical and psychological health problems of garment workers in the Fiji.

Chand, Anand

2006-09-01

This paper unravels the physical and psychological health problems of garment workers in Fiji. It is based on research work done between 1997-2007. Majority of the garment workers are women. The main physical health problems faced by workers are: 'Occupational fatigue syndrome', body pains, obesity, and bladder and kidney problems. The major psychological problems work stress and depression. Work stress and depression are caused by 'intensification of work' to meet daily targets, strict factory rules and regulations, poor pay, poor working conditions, in-human abuse, and fear of job loss. Since garment workers do not have much education and skills they have no other option but to work for the garment industry and suffer in silence.

2002-01-01

The effect of schistosomiasis on quality of life (QOL) and productivity of workers was examined. In a textile factory in Alexandria, Egypt, personal, occupational and sociodemographic data were collected from 172 workers with schistosomiasis and 172 workers without schistosomiasis. Several indicators of productivity and the World Health Organization QOL brief were used to determine the impact of schistosomiasis. The disease affected the general, physical and independence, psychological and spiritual, and social domains of QOL. Although the productivity score of workers with schistosomiasis did not differ significantly from the control group, they had significantly lower additional hours of work and lower total incentives/month. A significant relationship was found between severity of schistosomiasis and QOL domains and productivity indicators.

Thirty-eight workers from a factory producing nickel-cadmium and other types of batteries came to us for medical evaluation. They included 21 women and 17 men (seniority 2-20 years, age range 31-63 years), and represented a self-selected subset of 700-900 ever-employed and 200+ recently or currently employed workers in the factory. Thirty-four worked on the nickel-cadmium assembly line. Symptoms and signs included: headache in 34; weakness, fatigue and lassitude in 26; dizziness in 16; pruritus and skin eruptions in 37; gingivitis, teeth loss and caries in 34; nasal congestion, nosebleeds and anosmia in 30; cough, phlegm production, wheezing and shortness of breath in 26; "asthma" in 14; bone pain in 18; urinary frequency, beta 2 microglobulinuria and kidney stones in 17; and sterility or multiple abortions (33) in 8 of 21 women. One additional patient had died from an "amyotrophic lateral sclerosis-like syndrome", while CT scans in six workers revealed brain atrophy. One other worker had leukemia, and two had died from cancer (lung and pancreas). Those who had worked for more than 10 years had more symptoms and signs than shorter-term employees, especially neurological illness, bone pain and urinary tract problems, including beta 2 microglobulinuria. Past blood and urinary cadmium levels were in the range of 1.6-8.7 micrograms/dl and 8-306 micrograms/l, respectively. Our findings indicated that: a) health risks for workers were not confined to the nickel-cadmium assembly line or to older workers, b) hazardous exposures still existed and illness appeared in new workers after a clean-up and intervention program, and c) exposures involved increased risks for renal disease and cancers. Finally, there is a need to control exposures and determine health risks in the full cohort of those ever employed, in the workers' children, and in the surrounding environment (air, ground, water) due to the dumping of waste from the plant.

Individuals who work with pine in the furniture industry may be exposed to monoterpenes, the most abundant of which are α-pinene, β-pinene, and Δ(3)-carene. Monoterpenes are suspected to cause dermatitis and to harm the respiratory system. An understanding of the predictors of monoterpene exposure is therefore important in preventing these adverse effects. These predictors may include general characteristics of the work environment and specific work operations. We sought to assess the extent to which workers are exposed to monoterpenes and to identify possible predictors of monoterpene exposure in the pine furniture industry in Denmark. Passive measurements of the levels of selected monoterpenes (α-pinene, β-pinene, and Δ(3)-carene) were performed on 161 subjects from 17 pine furniture factories in Viborg County, Denmark; one sample was acquired from each worker. Additionally, wood dust samples were collected from 145 workers. Data on potential predictors of exposure were acquired over the course of the day on which the exposure measurements were recorded and could be assigned to one of four hierarchic ordered levels: worker, machine, department, and factory. In addition to univariate analyses, a mixed model was used to account for imbalances within the data and random variation with each of the hierarchically ordered levels. The geometric mean (GM) monoterpene content observed over the 161 measurements was 7.8 mg m(-3) [geometric standard deviation (GSD): 2.4]; the GM wood dust level over 145 measurements was 0.58 mg m(-3) (GSD: 1.49). None of the measured samples exceeded the occupational exposure limit for terpenes in Denmark (25 ppm, 150 mg m(-3)). In the univariate analyses, half of the predictors tested were found to be significant; the multivariate model indicated that only three of the potential predictors were significant. These were the recirculation of air in rooms used for the processing of wood (a factory level predictor), the presence of a supplementary cold air intake (departmental level), and the operation of a glue press (machine level). However, only one factory of the 17 examined used a supplementary cold air intake, and while very high monoterpene levels were observed there, this may be due to factors other than the supplementary intake. In contrast to the situation with wood dust, we found that the bulk of the variation in the data (65%) was attributable to variability on the factory level, with comparatively little being due to the departmental (16%) and machine (0.5%) levels. The fixed terms in the model accounted for 31.8% of the total variance. The predictors of monoterpenes are not the same as those for wood dust exposure; this has implications for the implementation of preventative measures in factories. In order to decrease monoterpene exposure, efforts should be focused on minimizing the recirculation of air in rooms used for woodworking and on increasing awareness of the importance of effective ventilation and enclosure when operating a glue press.

How is flow experienced and by whom? Testing flow among occupations.

The aims of this paper are to test (1) the factorial structure of the frequency of flow experience at work; (2) the flow analysis model in work settings by differentiating the frequency of flow and the frequency of its prerequisites; and (3) whether there are significant differences in the frequency of flow experience depending on the occupation. A retrospective study among 957 employees (474 tile workers and 483 secondary school teachers) using multigroup confirmatory factorial analyses and multiple analyses of variance suggested that on the basis of the flow analysis model in work settings, (1) the frequency of flow experience has a two-factor structure (enjoyment and absorption); (2) the frequency of flow experience at work is produced when both challenge and skills are high and balanced; and (3) secondary school teachers experience flow more frequently than tile workers.

Presenteeism has received increasing attention in occupational health research but the evidence for its association with perceived leadership is scant. To assess the association of perceived leadership and presenteeism among industrial workers. Survey responses from employees on perceived leadership were linked to the personnel register of a food industry company. The Presenteeism Scale method was used to determine the presenteeism percentage. Perceived leadership was measured as a composite variable of six individual items on motivating and participating leadership. Generalized linear models were used to determine the association of perceived leadership with presenteeism. There were 847 participants. The majority of office workers of both genders reported better perceived leadership than factory workers. We found that perceived poor leadership was associated with a higher likelihood of presenteeism (rate ratio (RR) 1.64, 95% confidence intervals (CIs) 1.51-1.78). However, there was variation amongst and within occupational groups and genders, with a higher risk of presenteeism amongst male factory workers (RR 2.28, 95% CI 2.02-2.52) than female office workers. Leadership was found to be significantly associated with presenteeism, with a greater risk of presenteeism in those reporting poor perceived leadership. The association between levels of perceived leadership and presenteeism was stronger in men than women. Organizations should focus on motivating leadership practices to reduce the risk of presenteeism, especially among men. © The Author 2017.

Rural-to-urban female migrant workers have a lower quality of life compared to the general population. Improving these conditions remains highly challenging. This paper reports the health-related quality of life (HRQoL) of the female migrant workers in an educational project. In this before-and-after study, a community-based health education intervention was developed to improve female migrant workers' HRQoL and job satisfaction. A factory was selected as the location to implement the trial, using a before-and-after design. The education intervention included distribution and free access to study materials, monthly lectures, and counseling. The primary endpoint was HRQoL, and gynecological disease and job satisfaction were secondary endpoints. We assessed HRQoL at baseline and at 6-month follow-up using the Health Survey Short Form (SF-36). Compared to the baseline assessment, the participants at the 6-month survey reported higher General Health scores (standardized-β coefficients (Betas) of β = 0.056; P <0.001), Vitality scores (β = 0.066; P <0.001), Mental Health scores (β = 0.062; P <0.001), mental component summary scores (β = 0.040; P <0.001), and job satisfaction (Odds Ratio [OR] 2.104, 95% confidence interval [CI] 1.837-2.408; P <0.01). A community-based educational intervention, targeted at female migrant workers, appears effective in improving HRQoL and job satisfaction.

The purpose of this descriptive correlational study was to identify knowledge levels and performance frequency of breast self-examination (BSE) and to examine variables related to breast cancer screening behaviors in a sample of Turkish women. Data were collected from a convenience sample of 103 Muslim female workers at a hazelnut factory in Ordu city, Turkey, using an adapted version of Champion's revised Health Belief Model Scale. Results showed that 26.2% of the women reported knowledge of BSE and 4.3% reported that they perform BSE. Higher health motivation, higher perceived self-efficacy of BSE, marital status, and familial breast cancer history were significantly associated with BSE performance. Higher levels of health motivation and higher perceived self-efficacy of BSE were also significantly associated with knowledge of BSE.

N-hexane neuropathy in offset printers.

1993-01-01

In an offset printing factory with 56 workers, 20 (36%) developed symptomatic peripheral neuropathy due to exposure to n-hexane. Another 26 workers (46%) were found to have subclinical neuropathy. The initial change in the nerve conduction study was reduced amplitude of the sensory action potentials, followed by reduced amplitude of the motor action potentials, reduction in motor conduction velocities and increase in distal latencies. These changes indicate primary axonal degeneration with secondary demyelination. Sural nerve biopsy in a severe case showed giant axonal swellings due to accumulation of 10nm neurofilaments, myelin sheath attenuation and widening of nodal gaps. The development of neuropathy bore no direct relationship to the duration of exposure, hence factors such as individual susceptibility may be important. Optic neuropathy and CNS involvement were uncommon and autonomic neuropathy was not encountered. Images PMID:8505647

2015-10-01

The aim of this study was to determine the effect of circadian rhythm disruption on cardiovascular autonomic regulation by examining potential differences in heart rate variability (HRV) between day- and night-shift workers. The study population consisted of 162 workers who worked both day and night shifts in two automobile manufacturing companies who underwent ambulatory 24-h electrocardiogram recording and completed questionnaires and sleep diaries. Both time and frequency domain indices of HRV were compared. HRV parameters (mean RR, SDNN, RMSSD, pNN50, TP, HF, LF, LF/HF ratio) reflecting sympathetic and parasympathetic modulation varied less with activity in night-shift workers. Circadian rhythm-mediated changes in autonomic regulation of the cardiovascular system were blunted in night-shift workers, which could contribute to an increased risk for cardiovascular disease in overnight workers.

Increased urinary excretion of thioether in new rubber workers

PubMed Central

Kilpikari, I; Savolainen, H

1982-01-01

ABSTRACT Urinary excretion of thioether before starting work and in the early work period in a rubber factory was measured in urine samples collected after one, two to four, and five or more months of starting work. The study population consisted of 84 new workers. The urinary excretion of thioether decreased after one month's exposure and increased thereafter up to five months. Measurement of urinary thioethers in groups of new workers is therefore informative of exposure to alkylating agents only after several months from starting work. This effect may be mediated by the induction of the pertinent metabolic pathway. PMID:7138800

Bladder tumours in rubber workers: a factory study 1946-1995.

Veys, C A

2004-08-01

Prior to December 1949, some British rubber industry workers were inadvertently exposed to the human bladder carcinogen beta-naphthylamine, which was present as a contaminant (at 0.25%) in antioxidants used in manufacturing. This study follows a composite cohort of 6450 men employed at a large tyre factory either during the 'at-risk' period or just after it. A group of 2090 at-risk men (employed 1945-1949) and 3038 men, first employed only after January 1950, when the carcinogen had been removed, were followed for their bladder cancer morbidity and mortality experiences. Fifty-eight tumours were registered for those at risk, whereas only 33.9 were expected at national standardized registration rates [SRRN = 171 and 95% confidence interval (CI) = 130-221]. Thirty-nine bladder tumours were reported for the post-1950 intake, whereas 38.3 were expected (SRRN = 102 and 95% CI = 72-139). The use of mortality data did not reveal any underlying hazard because 12 of the 58 at-risk workers with tumours were still alive at the study end date. In only 16 instances was bladder cancer actually certified as the underlying cause of death. Plotting cases by their location of work on a factory plan assisted the interpretation. A statistically significant elevated risk of bladder cancer for the exposed workforce was evident, but this reversed when the carcinogen was removed from processing in October 1949. The use of morbidity (incidence) data in long-term studies of occupational bladder cancer should be the required methodology if the hazard and risk are not to be underestimated.

The aim of the study was to assess occupational exposure to bisphenol A in Finland. Five companies took part in the research project: two paint factories (liquid and powder paints), a composite product factory, a thermal paper factory, and a tractor factory. Exposure was assessed by measuring total bisphenol A excretion (free and conjugated) from urine samples, and its concentrations in the air. The results revealed the specific work tasks in two of five companies in which significant occupational exposure to bisphenol A may occur. In the manufacturing of liquid paint hardener, urine samples collected after the working day showed bisphenol A levels of up to 100-170 µg l-1. Workers in thermal paper manufacturing were also exposed to bisphenol A, especially those working in the manufacture of coating material and operating coating machines. Median concentrations of the post-shift urine samples of coating machine workers were in the range of 130-250 µg l-1. The highest bisphenol A concentrations were in the range of 1000-1500 µg l-1. Recommendations for more effective personal protection resulted in decreased exposure, particularly among coating machine operators. In the rest of the companies, urinary bisphenol A levels were typically in the range of those of the general population. Bisphenol A concentrations in air samples were typically low (<40 µg m-3), except in some short-term duties related to the handling of solid bisphenol A (maximum 17.6 mg m-3). Low air levels, even in the companies with high urinary levels, suggest exposure via dermal contact. According to the results, exposure to bisphenol A may occur particularly in work tasks that involve the use of pure bisphenol A. In these tasks, special attention should be paid to the prevention of skin exposure. Inhalation exposure may become relevant in dusty work tasks. Since skin exposure is of potential concern in these tasks, biomonitoring is recommended as the method for assessing occupational exposure to bisphenol A. © The Author 2017.

Tobacco use is a major public health problem globally. According to the World Health Organization (WHO), tobacco is the second most important cause of death in the world. It is currently estimated to be responsible for about 5 million deaths each year worldwide. In India, it is responsible for over 8 lakh deaths every year. To estimate the prevalence of tobacco use among power loom workers in Mau Aima Town, District Allahabad, UP. Five hundred power loom workers were randomly chosen. Out of them 448 workers were interviewed through a questionnaire survey during May-June 2007. Data on demographics, education, and type of work were collected along with details regarding tobacco use and smoking status, duration of the habit, and daily consumption. Prevalence of tobacco chewing and/or bidi and cigarette smoking, and their sociodemographic correlates, were examined. The overall prevalence of tobacco use was 85.9%; the prevalence of smoking and tobacco chewing were 62.28% and 66.07%, respectively. Statistical analysis showed that smoking is more common in the elderly, while chewing gutka (a type of chewing tobacco) is popular among the younger age-groups. The prevalence of tobacco use among power loom workers is very high compared to that in general population. Immediate intervention programs are warranted to reduce the future burden of tobacco-related morbidity among these workers who are already exposed to the highly polluted environment in power loom factories.

A combination of several factors including a change in the paint application system; a lack of proper hygiene; and inadequate safety measures caused a severe health impact in the workers of some textile painting factories. This outbreak, mainly characterized by respiratory disorders, caused the death of six people and it has been classified as Ardystil syndrome. Fifty-two workers involved in the outbreak and 48 healthy subjects not known to have exposed to the potentially mutagenic agents participated in the study. The program evaluated possible genotoxic damage through the sister chromatid exchange (SCE) cytogenetic biomarker assay. We determined the frequency of SCE, high-frequency cells (HFCs), and a ratio, which can be considered as a new parameter, allowing for the study of the SCE distribution pattern among the chromosomes. There was no statistically significant difference in the SCE frequency and in the mean number of HFCs between the control and the Ardystil-affected groups. However, smoking increased the incidence of all parameters studied in both the case and control groups. This study shows that workers involved in the Ardystil syndrome did not suffer genotoxic damage as measured by SCE and HFCs when compared with the control group.

To evaluate the validity and reliability of the Portuguese language version of a work ability index. Cross sectional survey of a sample of 475 workers from an electrical company in the state of Sao Paulo, Southeastern Brazil (spread across ten municipalities in the Campinas area), carried out in 2005. The following aspects of the Brazilian version of the Work Ability Index were evaluated: construct validity, using factorial exploratory analysis, and discriminant capacity, by comparing mean Work Ability Index scores in two groups with different absenteeism levels; criterion validity, by determining the correlation between self-reported health and Work Ability Index score; and reliability, using Cronbach's alpha to determine the internal consistency of the questionnaire. Factorial analysis indicated three factors in the work ability construct: issues pertaining to 'mental resources' (20.6% of the variance), self-perceived work ability (18.9% of the variance), and presence of diseases and health-related limitations (18.4% of the variance). The index was capable of discriminating workers according to levels of absenteeism, identifying a significantly lower (p<0.0001) mean score among subjects with high absenteeism (37.2 points) when compared to those with low absenteeism (42.3 points). Criterion validity analysis showed a correlation between the index and all dimensions of health status analyzed (p<0.0001). Reliability of the index was high, with a Cronbach's alpha of 0.72. The Brazilian version of the Work Ability Index showed satisfactory psychometric properties with respect to construct validity, thus constituting an appropriate option for evaluating work ability in both individual and population-based settings.

Benzene, formaldehyde (FA) and trichloroethylene (TCE) are ubiquitous chemicals in workplaces and the general environment. Benzene is an established myeloid leukemogen and probable lymphomagen. FA is classified as a myeloid leukemogen but has not been associated with non-Hodgkin lymphoma (NHL), whereas TCE has been associated with NHL but not myeloid leukemia. Epidemiologic associations between FA and myeloid leukemia, and between benzene, TCE and NHL are, however, still debated. Previously, we showed that these chemicals are associated with hematotoxicity in cross-sectional studies of factory workers in China, which included extensive personal monitoring and biological sample collection. Here, we compare and contrast patterns of hematotoxicity, monosomy 7 in myeloid progenitor cells (MPCs), and B-cell activation biomarkers across these studies to further evaluate possible mechanisms of action and consistency of effects with observed hematologic cancer risks. Workers exposed to benzene or FA, but not TCE, showed declines in cell types derived from MPCs, including granulocytes and platelets. Alterations in lymphoid cell types, including B cells and CD4+ T cells, and B-cell activation markers were apparent in workers exposed to benzene or TCE. Given that alterations in myeloid and lymphoid cell types are associated with hematological malignancies, our data provide biologic insight into the epidemiological evidence linking benzene and FA exposure with myeloid leukemia risk, and TCE and benzene exposure with NHL risk.

Few studies have systematically investigated the impact of past occupational dust exposure on mental health. We examined whether retired factory workers exposed to any of the 4 dusts of silica, cement, coal and asbestos had more depressive symptoms and anxiety in southern China, which has experienced rapid economic development. We used data from the Guangzhou Biobank Cohort Study phase 3. Exposures, lifestyle, symptoms and medical history of the participants were assessed with a structured interview. Self-reported intensity and duration of past occupational dust exposure were used to derive cumulative exposure. Outcome measures were assessed by the 15-item Chinese version of the Geriatric Depression Scale (score ≥5) and the single-item on anxiety. The results revealed that 359 workers were exposed to at least one of the 4 dusts and that 1,253 were unexposed (controls). After adjustment of multiple confounders, greater risks of depressive symptoms were associated with high exposure to silica (odds ratio (OR) of 3.12, 95% CI of 1.17-8.31) and asbestos (OR of 6.90; CI of 1.29-36.75). Risks of anxiety were higher in those with low or high exposures to dust (OR of 2.01 and CI of 1.04-3.87 and OR of 2.29 and CI of 1.30-4.03, respectively) and cement (OR of 3.20 and CI of 1.27-8.07 and OR of 2.30 and CI of 1.09-4.87, respectively), and those with high exposure to silica (OR of 5.29, CI of 1.76-15.92). Past occupational exposures to silica, cement, coal and asbestos dusts were associated with adverse mental health outcomes in retired factory workers. The mechanism underlying the relationship between occupational exposures and psychological symptoms in later life needs to be further studied.

Little information exists about possible adverse health effects associated with workplace exposure to opiate compounds. We have previously reported opiate-specific IgG antibodies, positive epicutaneous tests, and pulmonary function decrements in workers exposed occupationally to opiates. In the present work, we extended these findings to investigate the effect of occupational opiate exposure on lymphocyte subpopulations and mitogen-induced lymphoblastogenesis. Thirty-three opiate-exposed workers and 8 nonexposed control workers were evaluated for lymphocyte subpopulation absolute numbers and percentages, by evaluating cell surface antigen expression with flow cytometry. A complete blood count with differential, common clinical chemistry parameters, and serum immunoglobulin levels were also evaluated. Opiate-exposed workers showed significantly (p < .05) increased absolute numbers and percentages of HLA-DR+ cells (MHC class II histocompatibility antigen), significantly (p < .01) decreased percentages of T helper-inducer (CD4+) cells, and significantly (p < .05) decreased numbers of basophils, compared with nonexposed opiate workers from the same factory. A trend toward reduction in the T helper-inducer (CD4+)/T cytotoxic-suppressor (CD8+) lymphocyte ratio was also evident. There was also a significant decrease in lymphocyte activity stimulated by pokeweed mitogen (p < .05) in opiate-exposed workers. These data indicate that occupational opiate exposure may change the number and types of circulating peripheral blood leukocytes, or alternatively, alter the expression of receptors on the surface of these cells. In addition, occupational opiate exposure appears to decrease the sensitivity of B-cells to pokeweed mitogen stimulation.(ABSTRACT TRUNCATED AT 250 WORDS)

Exposures to extremely low frequency (ELF) magnetic fields have not been documented extensively in occupations besides the work environments of electric or telephone utilities. A 1980-1993 study of childhood acute lymphoblastic leukemia (ALL) in Québec, Canada, gathered detailed information about the occupations of 491 mothers of ALL cases and mothers of a similar number of healthy controls. This information was combined with published data on the intensities of ELF magnetic fields associated with sources or work environments to estimate ELF magnetic field exposures for a wide range of jobs commonly held by women. Estimated exposures for 61 job categories ranged from 0.03 to 0.68 microT; the 25th, 50th, and 75th percentiles were 0.135, 0.17, and 0.23 microT, respectively. By job category, the most highly exposed jobs (>0.23 microT) included bakery worker, cashier, cook and kitchen worker, electronics worker, residential and industrial sewing machine operator, and textile machine operator. By work environment, the most highly exposed job categories were electronics worker in an assembly plant (0.70 microT) and sewing machine operators in a textile factory (0.68 microT) and shoe factory (0.66 microT). These results provide new information on expected levels of exposure in a wide range of jobs commonly held by women.

BTEX are important environmental pollutants, harmful to human through respiratory inhalation, digestive tract and skin contact, and also have teratogenic, mutagenic and carcinogenic effects. BTEX were detected in multi-media to identify their distributions and assess their human health risk in a pesticide factory in Hebei province. Purge and trap GC-MS, adsorption/thermal desorption GC chromatography and the health risk assessment model were applied, and corresponding management measures were proposed. The results showed that BTEX existed in soil, dust, air, groundwater and wastewater. The concentration of BTEX in dust of the production area was 7.33 mg x kg(-1), in particular the concentration of toluene was 5.64 mg x kg(-1), exceeding the Canadian industrial land standard. Building three scenarios for working more than 10 years, 20 years and 30 years, the total non-carcinogens index was 4.19 x10(-3), 8.25 x 10(-3) and 1.22 x 10(-2), respectively, all lower than 1; the carcinogens index of benzene was 1.70 x 10(-7), 3.34 x 10(-7) and 4.92 x 10(-7), respectively, all lower than 10(-6). It indicated that there was no significant non-carcinogens and carcinogens hazard to workers inside the factory, but they might be exposed to more health risks if their work experience increase. Finally, recommendations for improving the environmental quality and personnel security in the factory were proposed based on the research results.

[Application of health questionnaires for health management in small- and medium-sized enterprises].

Two kinds of health questionnaires, the Todai Health Index (THI) and Cumulative Fatigue Index (CFI), were applied as a screening device for health management of workers belonging to small-medium sized enterprises. A total of 495 workers composed of 452 male workers of a glass-bottle manufacturing factory and 43 male workers of a soft-drink bottling factory were the subjects of the present study. It was found that the two kinds of health questionnaires were different from each other and have their own characteristics. Twelve scales of THI were grouped into two, the first consisting of ten scales (SUSY, RESP, EYSK, MOUT, DIGE, IMPU, MENT, DEPR, NERV, and LIFE) and the second consisting of two scales (AGGR and LISC). Nine categories of CFI were grouped into one by using principal factor analysis. It was confirmed that the twelve scale scores of THI obtained at small-medium sized factories differed from those scale scores of a reference group investigated at a large-sized enterprise. It is on the basis of the scales of aggressiveness and lies and also of the scale of mental unstability which characterizes workers, locality, job (clerical or field work), and size of industry (large or small sized) that the difference could be evaluated. Urban life characterized by a life style of staying up late at night and waking up late in the morning has been reflected on the scale of life irregularity. Irregularity of life induced by transformation of working schedule, such as two or three shifts of work and overtime, was also reflected on this scale. Two scales of THI test, i.e., many subjective symptoms and digestive organ complaints, seemed to be the representative scales indicating a close relation between work load and health level. The discriminant score for diagnosis of psychosomatic diseases is considered to be one of the most useful assessments of the individual's health condition. As mentioned above, THI is recommended as a convenient assessment method for health management of workers and for screening individuals or groups requiring health management from the total respondents belonging to small-medium sized enterprises where health administrators or professionals for health services are not available. A combined use of THI and CFI is more effective in evaluating health status of field workers than the independent use of one of these two tests, because the causal relationship between work load and health status cannot be satisfactorily observed, only through THI.

Unilateral pseudogynecomastia: an occupational hazard in manual metal-pressing factories?

Five cases of unilateral occupation-related pseudogynecomastia are presented. All the patients in these cases worked in the same metal-pressing factory. One patient with grade 4 unilateral gynecomastia in the right breast presented to the authors' outpatient department asking persistently for surgery. He also reported that all his male colleagues working in the same business (a total of 5) had different degrees of unilateral gynecomastia. Their line of work involved holding a long round rod under the axilla and then pressing the distal end of it firmly against a spinning metal plate. The patient underwent a superior pedicle breast reduction, with 1,800 ml of tissue removed from his right breast. Unfortunately, the patient experienced partial nipple loss. However, he was satisfied with the final result, and good symmetry was achieved. All five patients who worked in the same metal-pressing factory presented with unilateral gynecomastia and were examined in our department. Their average age was 51.4 years. All the patients had normal hormonal and biochemical status, and the results of screening for toxins and heavy metal exposure were negative. All the patients were heavy smokers. At examination, none of the patients had nipple discharge or retraction, skin changes, galactorrhea, or lymphadenopathy. Examination showed one patient with grade 4, three patients had grade 2, and one patient with grade 1 unilateral gynecomastia. The authors believe that gynecomastia may be considered an occupational risk in analogous metal-pressing factories because all the workers in this factory presented with some degree of unilateral gynecomastia. However, they emphasize that this may simply be an observational phenomenon without a true cause and effect relationship.

From Danger and Motherhood to Health and Beauty: Health Advice for the Factory Girl in Early Twentieth-Century Britain1

LONG, VICKY; MARLAND, HILARY

A survey of government reports and the archives and journals of other agencies interested in industrial health in early twentieth-century Britain has led us to conclude that, in addition to apprehension about the potentially harmful impact of industrial work on the reproductive health of women, there was a great deal of interest in the health of young, unmarried girls in the workplace, particularly the factory. Adopting a broader time frame, we suggest that the First World War, with its emphasis on the reproductive health of women, was an anomalous experience in a broader trend which stressed the growing acceptability of women’s work within industry. Concern with girls’ health and welfare embraced hygiene, diet, exercise, recreation, fashion and beauty within and outside of the workplace, as well as the impact of the boredom and monotony associated with industrial work. The health problems of young women workers tended to be associated with behaviour and environment rather than biology, as were anxieties about the impact of work on morals, habits and character. Efforts to ensure that young female factory workers would be equipped to take their place as citizens and parents, we argue, often dovetailed rather than diverged with the ‘boy labour’ question.

We assessed the risk of liver injuries following low doses of N,N-dimethylformamide (DMF) below threshold limit values (20 mg/m) among leather industry workers and comparison groups. A cohort of 429 workers from a leather factory and 466 non-exposed subjects in China were followed for 4 years. Poisson regression and piece-wise linear regression were used to examine the relationship between DMF and liver injury. Workers exposed to a cumulative dose of DMF were significantly more likely than non-exposed workers to develop liver injury. A nonlinear relationship between DMF and liver injury was observed, and a threshold of the cumulative DMF dose for liver injury was 7.30 (mg/m) year. The findings indicate the importance of taking action to reduce DMF occupational exposure limits for promoting worker health.

Bisphenol A (BPA) is widely used in epoxy resins in China. There are few reports on the adverse health effects of occupational exposure to BPA. This study examined associations between urinary BPA concentrations in workers and laboratory parameters for health status. Spot urine checks at the end shift on Friday were used for cross-sectional analysis of BPA concentrations, and blood or urinary markers of liver function, glucose homeostasis, thyroid function and cardiovascular diseases were measured. The 28 participants were workers in two semiautomatic epoxy resin factories. The average urinary BPA concentration was 55.73±5.48 ng/ml (geometric mean ± geometric SD) (range 5.56-1934.85 ng/ml). After adjusting for urine creatinine (Cr), it was 31.96±4.42 μg/g Cr (geometric mean ± geometric SD) (range 4.61-1253.69 μg/g Cr). BPA feeding operators showed the highest concentrations, over 10 times those of the crushing and packing and office workers. Higher BPA concentrations were associated with clinically abnormal concentrations of FT3, FT4, TT3, TT4, thyroid-stimulating hormone, glutamic-oxaloacetic transaminase and γ-glutamyl transferase. Workers with higher BPA concentrations showed higher FT3 concentrations (linear trend: p<0.001). Bivariate correlation tests for laboratory analytes within normal limits showed FT3 to be positively associated with logged BPA concentrations, r=0.57, p=0.002. FT4 was positively associated with lactate dehydrogenase, r=0.45, p=0.020, and insulin was positively associated with thyroid-stimulating hormone with r=0.57, p=0.009. Higher occupational BPA exposure, reflected in urinary concentrations of BPA, may be associated with thyroid hormone disruption.

Aerosolization of fish proteins during seafood processing has been identified as a potential route for allergic sensitization and occupational asthma among workers involved in high-risk activities. The aim of this study was to develop immunological assays for the quantification of aerosolized fish antigens in a fish-processing factory. Polyclonal antibodies to the main fish species processed in the factory (anchovy and pilchard) were generated in rabbits and compared by ELISA inhibition assay and immunoblotting. These antisera were utilized to develop ELISA assays for the detection of fish antigens. The ELISA inhibition assays were evaluated by analyzing environmental air samples collected from three areas in a fish-processing factory: pilchard canning, fish meal production and lobster processing. By immunoblotting, the rabbit polyclonal antibodies demonstrated IgG antibody binding patterns comparable with IgE antibodies of fish-sensitized patients, particularly in regard to the major fish allergens parvalbumins. The sensitivity of the fish-specific ELISA assays developed was 0.5 microg/ml. The ELISA inhibition assays were able to differentiate between the two different fish species of interest but did not recognize a crustacean species. Notable differences in exposure levels to canned pilchard and anchovy antigens were demonstrated in the three different working areas of the factory, with assays having a detection limit as low as 105 ng/m(3). These ELISA-based assays are sensitive and specific to quantify differential exposure levels to fish antigens produced during fish processing, making it possible to investigate exposure-disease response relationships among workers in this industry.

Objectives In the cotton industry of Pakistan, 15 million people are employed and exposed to cotton dust, toxic chemicals, noise and physical hazards. The aim of this study was to determine the prevalence of health symptoms, particularly respiratory symptoms, and to measure cotton dust and endotoxin levels in different textile factories of Faisalabad, Pakistan. Methods A cross-sectional investigation was performed in a representative sample of 47 cotton factories in the Faisalabad region in Punjab, Pakistan. Respiratory symptoms of 800 workers were documented by questionnaire. Occupational safety in the factories was assessed by a trained expert following a checklist, and dust and endotoxin levels in different work areas were measured. Results Prevalence of respiratory disease symptoms (fever, shortness of breath, chest tightness and cough) was generally high and highest in the weaving section of the cotton industry (20–40% depending on symptoms). This section also displayed the poorest occupational safety ratings and the highest levels of inhalable cotton dust (mean±SD 4.6±2.5 vs 0.95±0.65 mg/m3 in compact units). In contrast, endotoxin levels were highest in the spinning section (median 1521 EU/m3), where high humidity is maintained. Conclusions There are still poor working conditions in the cotton industry in Pakistan where workers are exposed to different occupational hazards. More health symptoms were reported from small weaving factories (power looms). There is a dire need for improvements in occupational health and safety in this industrial sector with particular focus on power looms. PMID:25838509

To update the mortality experience of employees of a factory that produced cellulose triacetate film base at Brantham in the United Kingdom and generate information on the effects of exposure to methylene chloride, in particular, mortality from cardiovascular disease and cancers of the lung, liver and biliary tract, pancreas and brain. All 1,785 male employees with a record of employment at the film factory in 1946-1988 were followed through 2006, including 1,473 subjects exposed to methylene chloride on average for 9 years at a concentration of 19 ppm (8 h time-weighted average). A total of 559 deaths occurred during the follow-up period. In the subcohort of workers exposed to methylene chloride, substantially reduced mortalities compared with national and local rates were found for all causes, all cancers, and all the principal cancer sites of interest except for brain cancer. There was a small excess of brain cancer deaths (8 observed and 4.4 expected), but no evidence of an association with exposure to methylene chloride. Lung cancer mortality was significantly reduced in exposed workers, even compared to the low mortality rate in the local population (SMR 55). In contrast, mortality from ischaemic heart disease in exposed workers was slightly increased compared with local rates (SMR 102), but was lower in active employees (SMR 94; local rates), where a direct effect of exposure to methylene chloride should be concentrated. The study provided no indication that employment at the plant, or exposure to methylene chloride, had adversely affected the mortalities of workers.

Physical activity has been recommended as a strategy for improving sleep. Nevertheless, physical effort at work might not be not the ideal type of activity to promote sleep quality. The aim of this study was to evaluate the effects of type of job (low vs. high physical effort) and life-style on sleep of workers from an Amazonian Extractivist Reserve, Brazil. A cross-sectional study of 148 low physical activity (factory workers) and 340 high physical activity (rubber tappers) was conducted between September and November 2011. The workers filled out questionnaires collecting data on demographics (sex, age, occupation, marital status and children), health (reported morbidities, sleep disturbances, musculoskeletal pain and body mass index) and life-style (smoking, alcohol use and practice of leisure-time physical activity). Logistic regression models were applied with the presence of sleep disturbances as the primary outcome variable. The prevalence of sleep disturbances among factory workers and rubber tappers was 15.5% and 27.9%, respectively. The following independent variables of the analysis were selected based on a univariate model (p<0.20): sex, age, marital status, work type, smoking, morbidities and musculoskeletal pain. The predictors for sleep disturbances were type of job (high physical effort); sex (female); age (>40 years), and having musculoskeletal pain (≥5 symptoms). Rubber tapper work, owing to greater physical effort, pain and musculoskeletal fatigue, was associated with sleep disturbances. Being female and older than 40 years were also predictors of poor sleep. In short, these findings suggest that demanding physical exertion at work may not improve sleep quality.

The Decoy Effect as a Nudge: Boosting Hand Hygiene With a Worse Option.

PubMed

Li, Meng; Sun, Yan; Chen, Hui

2018-05-01

This article provides the first test of the decoy effect as a nudge to influence real-world behavior. The decoy effect is the phenomenon that an additional but worse option can boost the appeal of an existing option. It has been widely demonstrated in hypothetical choices, but its usefulness in real-world settings has been subject to debate. In three longitudinal experiments in food-processing factories, we tested two decoy sanitation options that were worse than the existing sanitizer spray bottle. Results showed that the presence of a decoy, but not an additional copy of the original sanitizer bottle in a different color, drastically increased food workers' hand sanitizer use from the original sanitizer bottle and, consequently, improved workers' passing rate in hand sanitary tests from 60% to 70% to above 90% for 20 days. These findings indicate that the decoy effect can be a powerful nudge technique to influence real-world behavior.

In a car factory employing 203 women machinists making seat covers more women complained of respiratory symptoms after the introduction of a new seat cover fabric, cropped nylon backed with flame-bonded polyurethane foam (CNPF). 68 women working in the trim shop were studied on the first day back at work after a week's holiday and then at the end of a working week; the incidence of wheezing and/or shortness of breath was greater than expected but there was no difference between peak flow rates. A second study of 192 of the 203 women working in the trim shop confirmed this recent increase in incidence of asthmatic symptoms and showed that significantly more machinists who had worked with this new fabric had a reduced peak flow rate than machinists who had not. Asthma developed in one subject when she was working in the factory sewing CNPF, when she was handling this fabric in the challenge cabinet in the laboratory, and on challenge with toluene di-isocyanate in the laboratory. Airways resistance increased in 3 other workers after exposure to CNPF in the laboratory. Low concentrations (between 0.0003 to 0.003 ppm) of toluene di-isocyanate were found in the air around this fabric. 4 of 9 women with symptoms had IgE antibodies to toluene di-isocyanate.

In two female workers (nonsmokers) and in one male worker (a smoker) employed in the same mill with a history of asbestosis, bronchogenic lung carcinoma type adenocarcinoma (women), respectively anaplastic carcinoma (a man) had developed. All the three patients worked in the same area in a spinning-mill. The duration of exposure to asbestos was relatively short (10 to 15 years) in female workers, while the duration of exposure to asbestos was much longer in a male worker (29 years), although it was intermittent. Dyspnea was the main and the only discomfort. In accordance with the International Labour Organization (ILO) classification, a chest radiograph revealed the lesions of s/t 1/2 and s/t 2/1 features. There was also a ventilation deficit (very decreased carbon monoxide diffusing capacity).

To form a new assessment method to evaluate postural workload comprehensively analyzing the dynamic and static postural workload for workers during their work process to analyze the reliability and validity, and to study the relation between workers' postural workload and work-related musculoskeletal disorders (WMSDs). In the study, 844 workers from electronic and railway vehicle manufacturing factories were selected as subjects investigated by using the China Musculoskeletal Questionnaire (CMQ) to form the postural workload comprehensive assessment method. The Cronbach's α, cluster analysis and factor analysis were used to assess the reliability and validity of the new assessment method. Non-conditional Logistic regression was used to analyze the relation between workers' postural workload and WMSDs. Reliability of the assessment method for postural workload: internal consistency analysis results showed that Cronbach's α was 0.934 and the results of split-half reliability indicated that Spearman-Brown coefficient was 0.881 and the correlation coefficient between the first part and the second was 0.787. Validity of the assessment method for postural workload: the results of cluster analysis indicated that square Euclidean distance between dynamic and static postural workload assessment in the same part or work posture was the shortest. The results of factor analysis showed that 2 components were extracted and the cumulative percentage of variance achieved 65.604%. The postural workload score of the different occupational workers showed significant difference (P<0.05) by covariance analysis. The results of nonconditional Logistic regression indicated that alcohol intake (OR=2.141, 95%CI 1.337-3.428) and obesity (OR=3.408, 95%CI 1.629-7.130) were risk factors for WMSDs. The risk for WMSDs would rise as workers' postural workload rose (OR=1.035, 95%CI 1.022-1.048). There was significant different risk for WMSDs in the different groups of workers distinguished by work type, gender and age. Female workers exhibited a higher prevalence for WMSDs (OR=2.626, 95%CI 1.414-4.879) and workers between 30-40 years of age (OR=1.909, 95%CI 1.237-2.946) as compared with those under 30. This method for comprehensively assessing postural workload is reliable and effective when used in assembling workers, and there is certain relation between the postural workload and WMSDs.

A young man was sent to our emergency unit because he had suffered from vomiting and cold sweating for 2 days. At the time he was admitted, he had no acute abdominal pains or gastrointestinal symptoms, and a physical examination revealed nothing but a faster heart rate and moist, flushing skin. The patient had worked for 6 years at a plastic bottle-recycling factory, but none of his co-workers had the same symptoms. Nevertheless, because the plant also recycled pesticide bottles, we suspected organophosphate pesticide intoxication. The patient's plasma acetylcholinesterase level was checked, revealing 1498.6 microU/L (normal range: 2,000-5, 000) on the first day and 1,379 microU/L on the second day. Upon questioning, the patient recalled that one of his shoe soles had been damaged and that his foot had been wet from walking all day in rain collected on the factory floor on the day that his symptoms first occurred. We conducted a study in the change of preshift and postshift acetylcholinesterase levels among six of his co-workers on a rainy day. We used the Wilcoxon signed rank test to compare the preshift and postshift plasma acetylcholinesterase levels; no significant difference was revealed (p = 0.600), leaving contamination via the damaged shoe sole suspect. We reviewed the literature on organophosphate intoxication; pesticide bottle-recycling factories were reported to be at a low risk of organophosphate toxicity in the working environment. However, because the potential risk of intoxication is still present, protective equipment such as clothing, gloves, and water-proof shoes should be worn, and employees should be educated on the potential risks.

Background The Malaysian Ministry of Health promotes breast self-examination (BSE) for all women, and Pap smear screening every three years for all sexually active women ages 20 years and above. The objectives of this paper were to examine the practice of these two screening tests among women production workers in electronics factories, and to identify factors related to practice. Methods This was a cross-sectional survey of women production workers from ten electronics factories. Data was collected by a self-administered questionnaire from a total of 1,720 women. The chi-square test, odds ratio and binomial logistic regression were used in bivariate and multivariate analysis. Results Prevalence rates were 24.4% for BSE once a month, and 18.4% for Pap smear examination within the last three years. Women who were significantly more likely to perform BSE every month were 30 years and older, Malays, with upper secondary education and above, answered the BSE question correctly, and had a Pap smear within the last three years. The proportion of women who had a Pap smear within the last three years were significantly higher among those who were older, married, with young children, on the contraceptive pill or intra-uterine device, had a medical examination within the last five years, answered the Pap smear question correctly, and performed BSE monthly. Conclusion Screening practice rates in this study were low when compared to national rates. Socio-demographic and health care factors significantly associated with screening practice are indicative of barriers which should be further understood so that more effective educational and promotional strategies could be developed.

There has been a dramatic increase in internal migrant workers in China over recent decades, and there is a recent concern of poor mental health particularly amongst younger or "new generation" migrants who were born in 1980 or later. A cross-sectional study was conducted in Guangzhou city between May and July in 2012. Mental wellbeing was measured using the World Health Organization Five-item Well-Being Index Scale and the 36 Item Short Form Health Survey mental health scale. Linear and logistic regression models were used to investigate the differences between migrant workers and their urban counterparts and between younger and older migrants. Migrant workers (n = 914) showed a small but significant advantage in mental wellbeing compared to their urban counterparts (n = 814). There was some evidence for age modification effect (p for interaction = 0.055-0.095); better mental wellbeing in migrants than urbanites were mainly seen in the older compared to the younger group, and the difference attenuated somewhat after controlling for income satisfaction. Older migrants showed better mental health than younger migrants. Factors that were independently associated with poor mental health in migrants included being male, longer working hours, and income dissatisfaction, whilst older age, factory job, high income, and increased use of social support resources were associated with reduced risk. Efforts to promote mental health amongst migrant workers may be usefully targeted on younger migrants and include measures aimed to improve working conditions, strengthen the social support network, and address age-specific needs.

This article presents cross-sectional investigation results of ophthalmological effects for the occupational exposure to carbon disulfide of workers at a large viscose fibre factory in the middle part of China. The total of 271 exposed subjects (191 males, 80 females) and 133 workers (93 males, 40 females) not exposed to any toxic agent in the working environment underwent ophthalmological examination. The self-administered questionnaire collected data on the medical history and ophthalmological complaints during the past three months. The ophthalmologic examination included routine examination for retinal capillary anomalies and and color vision with the FM 100-Hue test method. Nearly all subjects did not use respirators, smocks or aprons, gloves or other personal protective devices during work time. The average personal CS2 exposure level in the present study was 13.7-20.05 mg/m3. The FM 100-Hue test results showed that the total error scores of the exposed group, whether male or female, were higher than that of the control, the discrimination of the green and blue zones was also impaired significantly. A fundus examination showed no retinal capillary anomalies or other serious ophthalmological symptoms that may be related to effects of CS2. In conclusion, color vision was disturbed in workers exposed to CS2, at levels below the present threshold value. Reduced color discrimination may be attributed to long-term carbon disulfide exposure and suggests that health surveillance of workers exposed to carbon disulfide should include the FM 100-Hue Test as a sensitive and easy method.

Depression is a growing health issue in both developed and developing countries. General unawareness at the population level, lack of training among health care providers and scarcity of resources including treatment opportunities may conceal the real burden of depression in developing countries, and more epidemiological studies on its prevalence and risk factors are critically needed. This study reports the prevalence of depression and its associated risk factors among female garment factory workers in Bangladesh - a major supplier country of clothes for the Western market. This research should generate useful evidence for national and international stakeholders who have an interest in improving health, safety and well-being of outsourced factory workers. A survey was conducted on a sample of 600 lower socio-economic status working women including garment workers. This survey collected data on demographic and health profile of these workers. The primary outcome was depression as measured by Patient Health Questionnaire 9. It also obtained data on traumatic life events and post-traumatic stress disorder. The prevalence of depression was 23.5%: 20.9% among garment workers and 26.4% among others. Part-time employment (odds ratio-OR): 2.36, 95% confidence interval (95% CI): 1.01-5.51), chronic pain (OR: 1.67, 95% CI: 1.01-2.78), two or more traumatic life events (OR: 6.43, 95% CI: 2.85-14.55) and dysuria (OR: 2.50, 95% CI: 1.02-6.15) were found to be significantly associated with depression among these workers in multivariate regression model. Depression prevalene lowered by 11% among these workers for every additional monthly earning of 1,000 taka (US$12). Depression is a multifaceted health issue with many personal, social, economic and health determinants and consequences. This study demonstrates that the prevalence of moderate-to-severe depression among working women in Bangladesh is quite high. Prevention and treatment of depression in developing countries and societies can reduce suffering, lower incidence of suicide, and prevent economic loss. Creating awareness on outsourced workers' poor mental health may help in developing initiatives to protect and preserve their well-being.

With this premise, then, in order to identify bottlenecks and other engineering problems that could cause discomfort and motivation lack among workers, leading directly to the loss of the product quality, the assembly sector of women's shoes factory was characterized.

History of asbestos related disease

Bartrip, P

2004-01-01

The first medical article on the hazards of asbestos dust appeared in the British Medical Journal in 1924. Following inquiries by Edward Merewether and Charles Price, the British government introduced regulations to control dangerous dust emissions in UK asbestos factories. Until the 1960s these appeared to have addressed the problem effectively. Only then, with the discoveries that mesothelioma was an asbestos related disease and that workers other than those employed in the dustiest parts of asbestos factories were at risk, were the nature and scale of the hazard reassessed. In Britain, America, and elsewhere new and increasingly strict regulations were enacted. PMID:14970292

An outbreak of dermatitis in a car assembly factory is described; it affected 50 workers who handled rubber weatherstrips coated with an adhesive. The adhesive was found to contain para-tertiary butyl phenol (P.T.B.P.) formaldehyde resin. Of those patch tested 70% gave positive reactions to the adhesive and 65% to the resin. Improved methods of handling and personal protection succeeded in arresting the occurrence of dermatitis. Barrier creams gave no protection in these circumstances. The episode illustrates the different preventive control methods which have to be tried when dealing with a simple skin hazard which cannot be abolished. Images PMID:5904100

To investigate the current supply and use of personal protective equipment (PPE) among rural-to-urban migrant workers in small and medium enterprises (SMEs) in Zhongshan and Shenzhen, China and the influential factors for the use of PPE, and to provide a basis for better occupational health services and ensuring the health of migrant workers. Multi-stage sampling was used to select 856 migrant workers from 27 SMEs in Zhongshan and Shenzhen, and face-to-face questionnaire survey was conducted in these subjects. Statistical analysis was performed by one-way analysis of variance, chi-square test, and logistic regression. Of all migrant workers, 38.67%were supplied with free PPE by the factory, and this rate varied across industries (furniture industry: 45.81%; electronic industry: 31.46%) and SMEs (medium enterprises: 42.13%; small enterprises: 39.20%; micro enterprises: 22.16%); 22.43% insisted on the use of PPE. The logistic regression analysis showed that factors associated with the use of PPE included sex, age, awareness of occupational health knowledge, and the size of enterprise. The rates of supply and use of PPE among migrant workers are low. The larger the enterprise, the better the supply of PPE. Male gender, being elder, and high occupational health knowledge score were favorable factors for the use of PPE, while small enterprise size was the unfavorable factor for the use of PPE.

Behavioral surveys help interpret the magnitude of HIV/AIDS. We analyzed indicators of knowledge on HIV/AIDS and condom use among sub populations selected for behavioral surveillance in Ethiopia. We used 2005 HIV/AIDS behavioral data from ten target groups. These were female sex workers, defense forces, police force, pastoralists, truck drivers, intercity bus drivers, road construction workers, teachers, factory workers and people in ANC catchment areas. Data from 14,524 individuals were analyzed. The majority were males (63.6%). Overall, knowledge of the three preventive methods, misconceptions and comprehensive knowledge was 57%, 75% and 18.5%, respectively. Female sex workers and the defense force showed some behavioral change in using a condom during the most recent sexual encounter and consistently used a condom with non-regular sexual partners and paying partners. Women, pastoralists and the illiterate were less likely to use condom. Misconceptions about the transmission of HIV were high and comprehensive knowledge about HIV & AIDS was low, particularly among pastoralists. Consistent condom use and condom use during the last sexual encounter were high among both female sex workers and defense force employees, both with paying and non-regular sexual partners. This might be a positive sign, though a considerable proportion in each target group did not report using a condom during sex with non-regular partners.

One century ago, the landmark fire at the Triangle Shirtwaist Factory in New York City claimed the lives of 146 garment workers and helped spur the adoption of fire safety measures and laws targeting dangerous working conditions. Since that time, continuing advances have been made to address the threat of fire-in workplace fire safety practices and regulations, in training and safety requirements for firefighters and first responders, and in hazard communication laws that enhance disaster planning and response. Recent high profile events, including the West, Texas fertilizer plant explosion, derailments of fuel cargo trains, and garment factory fires in Bangladesh, have brought renewed attention to fire as a workplace health and safety issue and to the unevenness of safety standards and regulatory enforcement, in the United States as well as internationally. In this article, we provide an overview of fire as a workplace health and safety hazard and an introduction to the essays included in this special issue of New Solutions on fire and work. © 2015 SAGE Publications.

Air pollution and its adverse health effect represent a global issue. Long term or permanent exposure at low doses of toxic material may increase the number of new appeared severe respiratory diseases and may aggravate most of the existing chronic cases. In the present study, the main toxic aerosols released by the greatest chemical factory in Transylvania were analyzed and their health impacts were measured. We have used in our trial biologic monitoring 1786 employees from a chemical factory in a transversal descriptive study. In the same time, we have noticed environmental determination of air quality and also, we have checked the health status and other 90 cases from a nonchemical factory. In this factory there are also pneumotrop harms. Results of our study give useful information regarding workers health status, with possibility to make pollution-medical condition association: there was no significant association between occurrence of decreased lung function tests and exposure of chemical irritants compared to the second investigated factory. Exposure to pneumotrope hazards imposes safeguards to protect health and biological monitoring has proven absolutely necessary to do so. Last but not least, lifestyle monitoring is to be effective.

Migrant workers have become a vital labor supply to China's economy. Their migration process and work conditions may influence their health and work ability. The work ability of migrant workers in China and the influence of the migration process on work ability have not been explored extensively in previous studies. The objective of this study is to evaluate the association of migration characteristics and work-related factors with work ability among migrant workers in the Pearl River Delta. In this cross-sectional survey, the study population consisted of 907 migrant workers from ten factories in the Pearl River Delta who were exposed to organic solvents during work. The primary dependent variable of the study was work ability, measured by the Work Ability Index (WAI). The independent variables were individual characteristics, migration characteristics, and work-related factors. Logistic regression models were used to determine the influence of different factors on work ability and three dimensions of WAI. The result shows that among migration characteristics, social support was significantly associated with all three dimensions of the work ability index. Permanent migration intention and longer length of migration were negatively associated with the mental resource dimension of WAI. WAI was also influenced by individual and work-related factors. The findings of this study suggest that expanding migrants' social networks and social support systems in their work place or living community, (i.e. expanding the functions of labor unions) would be an effective way to improve migrant workers' work ability. Improving of migrant workers' physical and psychosocial related work environments would also increase their work ability.

Prediction of hearing loss in noisy workplaces is considered to be an important aspect of hearing conservation program. Artificial intelligence, as a new approach, can be used to predict the complex phenomenon such as hearing loss. Using artificial neural networks, this study aims to present an empirical model for the prediction of the hearing loss threshold among noise-exposed workers. Two hundred and ten workers employed in a steel factory were chosen, and their occupational exposure histories were collected. To determine the hearing loss threshold, the audiometric test was carried out using a calibrated audiometer. The personal noise exposure was also measured using a noise dosimeter in the workstations of workers. Finally, data obtained five variables, which can influence the hearing loss, were used for the development of the prediction model. Multilayer feed-forward neural networks with different structures were developed using MATLAB software. Neural network structures had one hidden layer with the number of neurons being approximately between 5 and 15 neurons. The best developed neural networks with one hidden layer and ten neurons could accurately predict the hearing loss threshold with RMSE = 2.6 dB and R(2) = 0.89. The results also confirmed that neural networks could provide more accurate predictions than multiple regressions. Since occupational hearing loss is frequently non-curable, results of accurate prediction can be used by occupational health experts to modify and improve noise exposure conditions.

Epidemiological studies suggest that trichloroethylene (TCE) exposure may be associated with renal cancer. The biological mechanisms involved are not exactly known although nephrotoxicity is believed to play a role. Studies on TCE nephrotoxicity among humans, however, have been largely inconsistent. We studied kidney toxicity in Chinese factory workers exposed to TCE using novel sensitive nephrotoxicity markers. Eighty healthy workers exposed to TCE and 45 comparable unexposed controls were included in the present analyses. Personal TCE exposure measurements were taken over a 2-week period before urine collection. Ninety-six percent of workers were exposed to TCE below the current US Occupational Safety and Health Administration permissible exposure limit (100 ppm 8h TWA), with a mean (SD) of 22.2 (35.9) ppm. Kidney injury molecule-1 (KIM-1) and Pi-glutathione S transferase (GST) alpha were elevated among the exposed subjects as compared with the unexposed controls with a strong exposure-response association between individual estimates of TCE exposure and KIM-1 (P < 0.0001). This is the first report to use a set of sensitive nephrotoxicity markers to study the possible effects of TCE on the kidneys. The findings suggest that at relatively low occupational exposure levels a toxic effect on the kidneys can be observed. This finding supports the biological plausibility of linking TCE exposure and renal cancer.

A hybrid simulation approach for integrating safety behavior into construction planning: An earthmoving case study.

PubMed

Goh, Yang Miang; Askar Ali, Mohamed Jawad

2016-08-01

One of the key challenges in improving construction safety and health is the management of safety behavior. From a system point of view, workers work unsafely due to system level issues such as poor safety culture, excessive production pressure, inadequate allocation of resources and time and lack of training. These systemic issues should be eradicated or minimized during planning. However, there is a lack of detailed planning tools to help managers assess the impact of their upstream decisions on worker safety behavior. Even though simulation had been used in construction planning, the review conducted in this study showed that construction safety management research had not been exploiting the potential of simulation techniques. Thus, a hybrid simulation framework is proposed to facilitate integration of safety management considerations into construction activity simulation. The hybrid framework consists of discrete event simulation (DES) as the core, but heterogeneous, interactive and intelligent (able to make decisions) agents replace traditional entities and resources. In addition, some of the cognitive processes and physiological aspects of agents are captured using system dynamics (SD) approach. The combination of DES, agent-based simulation (ABS) and SD allows a more "natural" representation of the complex dynamics in construction activities. The proposed hybrid framework was demonstrated using a hypothetical case study. In addition, due to the lack of application of factorial experiment approach in safety management simulation, the case study demonstrated sensitivity analysis and factorial experiment to guide future research.

Benzene, formaldehyde (FA) and trichloroethylene (TCE) are ubiquitous chemicals in workplaces and the general environment. Benzene is an established myeloid leukemogen and probable lymphomagen. FA is classified as a myeloid leukemogen but has not been associated with non-Hodgkin lymphoma (NHL), whereas TCE has been associated with NHL but not myeloid leukemia. Epidemiologic associations between FA and myeloid leukemia, and between benzene, TCE and NHL are, however, still debated. Previously, we showed that these chemicals are associated with hematotoxicity in cross-sectional studies of factory workers in China, which included extensive personal monitoring and biological sample collection. Here, we compare and contrast patterns of hematotoxicity, monosomy 7 in myeloid progenitor cells (MPCs), and B-cell activation biomarkers across these studies to further evaluate possible mechanisms of action and consistency of effects with observed hematologic cancer risks. Workers exposed to benzene or FA, but not TCE, showed declines in cell types derived from MPCs, including granulocytes and platelets. Alterations in lymphoid cell types, including B cells and CD4+ T cells, and B-cell activation markers were apparent in workers exposed to benzene or TCE. Given that alterations in myeloid and lymphoid cell types are associated with hematological malignancies, our data provide biologic insight into the epidemiological evidence linking benzene and FA exposure with myeloid leukemia risk, and TCE and benzene exposure with NHL risk.

This is a follow up study on rescue workers participating in the primary rescue during and immediately after the explosion of a firework factory. We aimed to estimate the possible PTSD prevalence at five and 18 months post disaster, determining if the level of PTSD symptoms at 18 months could be predicted from factors measured at five months. We included measures of posttraumatic symptoms, social support, locus of control and demographic questions. The possible PTSD prevalence rose from 1.6% (n = 465) at five months post disaster to 3.1% (n = 130) at 18 months. A hierarchical linear regression predicted 59% of PTSD symptoms variance at 18 months post disaster. In the final regression, somatization explained the greatest part of the symptom variance (42%), followed by locus of control (29%) and major life events prior to and right after the disaster (23%). Rescue workers seemed to be relatively robust to traumatic exposure: The prevalence of possible PTSD in our study was even lower than previous studies, probably because of the less severe consequences of the disaster studied. Furthermore, we found that PTSD symptom level at 18 months post disaster was highly predicted by psychological factors, particularly by somatization. However, further investigations of traumatic responding are required in this population.

To evaluate the effectiveness of an intervention program on promoting the use of contraceptives in migrant population working in factories, and to compare the difference of results between the basic intervention mode and the comprehensive intervention mode. This was an epidemiologic intervention study carried out in each 2 factories in Shenzhen and Dongguan among migrant workers by comparing the effectiveness of a baseline survey and a end-line survey. The basic intervention mode was composed of spreading contraceptives and reproductive health information, conducting education and communication and providing references to access free services from family planning clinics (IEC). The comprehensive intervention mode provided more services on face to face counseling and distributing free contraceptives. The demographic characteristics of subjects before and after surveys were comparable. Whether in the basic group or comprehensive mode group, the awareness of contraceptive/reproductive health knowledge was increased significantly after intervention (P = 0.000), and the pass rate was higher in the comprehensive intervention group (P = 0.000). The self-reported most frequently used contraceptives was condoms. The proportion of using condoms and purchasing condoms was increased after intervention (P = 0.000) from 69.7% and 67.7% before intervention to 84.9% and 90.2% after basic intervention and 87.1% and 95.1% after comprehensive intervention. The proportion of using contraceptives every time was increased from 35.7% before intervention to 38.1% after basic intervention (P = 0.018) and to 42.9% after comprehensive intervention (P = 0.000). Intervention measures based on implementing in factories were effective in promoting contraception among migrant workers, and the integration of counseling and free contraceptive services with IEC was better. Carrying on and extending this kind of intervention measures to other migrant population in similar conditions is suggested.

In the cotton industry of Pakistan, 15 million people are employed and exposed to cotton dust, toxic chemicals, noise and physical hazards. The aim of this study was to determine the prevalence of health symptoms, particularly respiratory symptoms, and to measure cotton dust and endotoxin levels in different textile factories of Faisalabad, Pakistan. A cross-sectional investigation was performed in a representative sample of 47 cotton factories in the Faisalabad region in Punjab, Pakistan. Respiratory symptoms of 800 workers were documented by questionnaire. Occupational safety in the factories was assessed by a trained expert following a checklist, and dust and endotoxin levels in different work areas were measured. Prevalence of respiratory disease symptoms (fever, shortness of breath, chest tightness and cough) was generally high and highest in the weaving section of the cotton industry (20-40% depending on symptoms). This section also displayed the poorest occupational safety ratings and the highest levels of inhalable cotton dust (mean±SD 4.6±2.5 vs 0.95±0.65 mg/m(3) in compact units). In contrast, endotoxin levels were highest in the spinning section (median 1521 EU/m(3)), where high humidity is maintained. There are still poor working conditions in the cotton industry in Pakistan where workers are exposed to different occupational hazards. More health symptoms were reported from small weaving factories (power looms). There is a dire need for improvements in occupational health and safety in this industrial sector with particular focus on power looms. Published by the BMJ Publishing Group Limited.

Endotoxin exposure associated with organic dust exposure has been studied in several industries. Coffee cherries that are dried directly after harvest may differ in dust and endotoxin emissions to those that are peeled and washed before drying. The aim of this study was to measure personal total dust and endotoxin levels and to evaluate their determinants of exposure in coffee processing factories. Using Sidekick Casella pumps at a flow rate of 2l/min, total dust levels were measured in the workers' breathing zone throughout the shift. Endotoxin was analyzed using the kinetic chromogenic Limulus amebocyte lysate assay. Separate linear mixed-effects models were used to evaluate exposure determinants for dust and endotoxin. Total dust and endotoxin exposure were significantly higher in Robusta than in Arabica coffee factories (geometric mean 3.41 mg/m(3) and 10 800 EU/m(3) versus 2.10 mg/m(3) and 1400 EU/m(3), respectively). Dry pre-processed coffee and differences in work tasks explained 30% of the total variance for total dust and 71% of the variance for endotoxin exposure. High exposure in Robusta processing is associated with the dry pre-processing method used after harvest. Dust and endotoxin exposure is high, in particular when processing dry pre-processed coffee. Minimization of dust emissions and use of efficient dust exhaust systems are important to prevent the development of respiratory system impairment in workers.

To determine the cause of acute poisoning occurred in a factory in Yangjiang city, Guangdong province. In a cross-sectional study, interviews were conducted with the administrators of the factory and the local physician. A review was conducted on the water system used for industrial purposes and a separate system used by workers for drinking water. Treatment and discharge of industrial waste water were examined. Face-to-face interview was conducted to identify risk of exposure for illness among workers. A total number of 36 cases were identified in the plant and the attack rate was 16.4% (36/220). The incubation period (time between drinking polluted water and the onset of symptoms) had a median of 90 minutes (range: 30 - 230 minutes). Consuming water at the factory increased the attack rate and a dose-response effect was identified (chi(2)(trend) = 79.115, P < 0.01). The nitrite content of residuals in drinking water exceeded the WHO standard (1 ppm). The accident of acute poisoning was due to drinking water contaminated with sodium nitrite. The prevention of drinking water contaminated by toxic chemicals like sodium nitrite, and the design of industrial and potable water supply system need to be carefully reviewed. Regulations should be developed and enforced to minimize the impact of industrial waste water discharges to guarantee the access to clean drinking water.

Across the United States there has been a spate of legislative bills and initiatives that blatantly stigmatize and discriminate against the lesbian, gay, bisexual, and transgender (LGBT) community. This study was a cross-sectional, exploratory survey designed to measure the attitudes, perceptions, and behaviors of Tennessee social workers and future social workers toward the LGBT population and toward proposed discriminatory legislation. A 3-way factorial ANOVA investigated the effects of political affiliation, religious affiliation, and social contact on the dependent measures. Significant main effects were found. Self-reported political affiliation was found to be the most important factor predicting LGBT acceptance and LGBT respect among this sample.

In Taiwan, secondary copper smelters and zinc recovery plants primarily utilize recovering metal from scrap and dross, and handles mostly fly ash and slag with high temperature to produce ZnO from the iron and steel industry. The materials may contain organic impurities, such as plastic and organic chloride chemicals, and amounts of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) are produced during the smelting process. Therefore, secondary metal recovery industries are major emission sources of PCDD/Fs, which may have been demonstrated to elicit oxidative stress and to involve the production of plasma malondialdehyde (MDA). Many studies have also indicated that the intake of antioxidants, smoking, age and exposure to environmental pollutants may be implicated to DNA damage or lipid peroxidation. This study therefore aims to elucidate the roles of occupational exposure like joining the smelting work, age, smoking and alcohol status, and antioxidant intake on oxidative damage in secondary metal recovery workers in Taiwan. 73 workers were recruited from 2 secondary metal recovery plants. The analysis of 8-hydroxydeoxyguanosine (8-OH-dG) in urine, DNA strand breakage (comet assay) and lipid peroxidation (MDA) in blood samples were completed for all of the workers. The results showed that the older subjects exhibited significantly lower levels of 8-OH-dG and MDA than younger subjects. Our investigation also showed that working departments were in related to plasma MDA and DNA strand breakage levels of nonsmokers, however, the observation become negligible in smokers. And it is implicated that cigarette type might affect 8-OH-dG levels in secondary metal recovery workers. Since, adding to results above, the MDA level in production workers was significantly higher than those in managerial departments, it is important for the employers to make efforts on improving occupational environments or serving protective equipments to protect workers in secondary metal recovery factories.

The provision of reinforcements or boosters to interventions is seen as a logical approach to enhancing or maintaining desired behavior. Empirical studies, however, have not confirmed the effectiveness of boosters nor assessed the optimum number of boosters or the timing for their delivery. This randomized controlled trial contrasted the effect of four booster conditions (a). 30 days; (b). 90 days; (c). 30 and at 90 days; and (d). no boosters of the intervention to increase the use of hearing protection devices (HPDs). A total of 1325 factory workers completed a computerized questionnaire and were randomly assigned to one of three computer-based (tailored, nontailored predictor-based, or control) multimedia interventions designed to increase the use of hearing protection devices. After the intervention, colorful boosters specific to the type of training received were mailed to workers' homes. Posttest measures of use were administered at the time of their next annual audiogram 6 to 18 months after the intervention. RESULTS Repeated measures of analysis of variance (ANOVA) showed a significant main effect for the booster (after 30 days) in the group that received tailored training (F[3442] = 2.722; p =.04). However, in the assessment of the interaction between time (pretest and posttest) and boosters (four groups), the ANOVA did not find significant differences in hearing protection device use for any of the training groups. To assess for significant differences between groups, post hoc comparisons were conducted at the pretest and posttest for the total sample and for the subsample of workers who reported using hearing protection devices less than 100% of the time needed. Sheffé contrasts by intervention group, gender, ethnicity, and hearing ability found no significant changes in the mean use of hearing protection devices for the booster groups. Although the provision of boosters represented a considerable commitment of resources, their use was not effective in this study. However, it would be premature to eliminate boosters of interventions. Further study is needed to explore the effects of different booster types for increasing the use of hearing protection devices, and to assess carefully the effects of boosters on other health behaviors in studies with controlled designs.

The Structural Invisibility of Outsiders: The Role of Migrant Labour in the Meat-Processing Industry

Lever, John; Milbourne, Paul

2016-01-01

This article examines the role of migrant workers in meat-processing factories in the UK. Drawing on materials from mixed methods research in a number of case study towns across Wales, we explore the structural and spatial processes that position migrant workers as outsiders. While state policy and immigration controls are often presented as a way of protecting migrant workers from work-based exploitation and ensuring jobs for British workers, our research highlights that the situation ‘on the ground’ is more complex. We argue that ‘self-exploitation’ among the migrant workforce is linked to the strategies of employers and the organisation of work, and that hyper-flexible work patterns have reinforced the spatial and social invisibilities of migrant workers in this sector. While this creates problems for migrant workers, we conclude that it is beneficial to supermarkets looking to supply consumers with the regular supply of cheap food to which they have become accustomed.

1993-01-01

A noise level dosimetry and audiometric testing were conducted in a cellulose factory to determine the hazardous noise level and the prevalence of noise induced hearing loss among the exposed workers. The noise level was recorded up to 90 db (A) in several working areas. 18 workers, potentially exposed to noise injury, evidenced a significant hearing loss. While no evidence of noise injury was recorded in a control group of 100 subjects. This finding suggest a strict relationship between audiometric tests, the noise level recorded in the working place and the working seniority of exposed employers.

To evaluate the possible influence of mercury vapour on female reproduction, 153 women working in a mercury vapour lamp factory have been compared with 193 women employed in another factory of the same company, where mercury was not used. Both groups of subjects were exposed to stress factors (noise, rhythms of production, and shift work). The production process has been analysed by inspection of the plants and by collective discussions with "homogeneous groups" of workers; a retrospective inquiry into work history and reproductive health events has been subsequently performed by an individual interview. Women exposed to mercury vapour currently not exceeding the time weighted average air concentration of 0.01 mg/m3 declared higher prevalence and incidence rates of menstrual disorders, primary subfecundity, and adverse pregnancy outcome; however, the progression of these problems with the level of exposure to mercury inside the same factory was not always clear. The results of this study neither prove nor exclude the possibility that occupational exposure to this concentration of mercury has a negative effect on female reproduction.

Sharma, Kavya; Zodpey, Sanjay P; Tiwari, Rajnarayan R

2013-07-01

Industrial growth in India has resulted in increased employment opportunities, thereby inflating the size of the workforce engaged in both organized and unorganized sectors. This workforce is exposed to various occupational factors at workplace and hence is susceptible to occupational diseases, which requires trained occupational health manpower. The present study is undertaken to estimate the need and supply gap of occupational health manpower, based on present regulations. The total workforce in the organized sector in India is 26.92 million. There are 254,951 working registered industrial factories in India, with about 11.16 million workers. These factories have employed 6953 factory medical officers (FMOs) and 2308 safety officers (SOs). Hence, for 26.92 million of total workforce engaged in organized sector, we would require a total of 16,728 FMOs and 5619 SOs, thereby estimating the deficit of 58% for FMOs and 59% for SOs based on current ratio of employment.

An unexpected mortality of more than 300 cattle was investigated near a metal recovery factory located in a rural area of the Thane district of India. The factory was engaged in reclaiming lead, aluminum, tin, and zinc from discarded lead storage batteries and soft drink cans. The environmental samples (soil, leaves, grass, slag, water, and sediment), human blood and hair and animal samples (blood, urine, peritoneal fluid, liver, kidney, cow dung, ribs, and femur), collected for analysis revealed toxic levels of lead, cadmium, and chromium. Clinical examination of factory workers and school children revealed cough, fever, gastric problems, abdominal pain, skin lesions (scabies), and blue line on gums. Histopathological examination of animal tissues revealed chronic pathology with lead inclusion bodies in hepatocytes and renal tubules. Based on environmental, clinical, analytical, and histopathological observations, the mortality has been attributed to toxic levels of metals in the body and the malnourished status of the animals.

Serum lipid, uric acid and glucose levels were measured in four groups of Black male factory workers 1 hour after an oral glucose load. These groups comprised non-obese manual, obese manual, non-obese clerical and obese clerical workers. Obese men had significantly higher serum uric acid, total cholesterol and triglyceride levels and lower high=density lipoprotein (HDL) cholesterol levels than non-obese men. Serum glucose and low-density lipoprotein (LDL) cholesterol values were also higher in obese than in non-obese men, but the differences were not significant. Clerical workers had higher levels than manual workers for most of the biochemical variables measured, but only in the case of uric acid was the difference significant. Possible reasons for the fact that the effect of occupation on the variables was slight are briefly discussed.

Given the hazardous nature of the work in steel factories and that the staff has to deal with hazardous equipment and machines, improper sleep quality and drowsiness among the works tackles performance and boosts rate of job accidents. This study is aimed to survey the quality of sleep and sleepiness status and the pertinent factors among the workers in a rolling mill and a steel production company in Tehran, Iran. In a Cross-Sectional study 2011, 180 workers were selected randomly from a rolling mill and a steel production company in Tehran. A questionnaire was designed to collect demographic data and variables of work condition. Pitersborg's sleep quality questionnaire was used to survey quality and problems of Participants' sleep. Epworth Sleepiness questionnaire was used to deals with sleepiness during work, studying, watching TV, or during time spent in public. Average score of sleep quality for the fixed shift staff and changing shift staff were 7.5±2.82 and 8.49±2.95 respectively. Surveys of sleep quality for the two groups of the participants based on T-test showed a significant difference between the two groups so that the changing shift staff group suffered poorer sleep quality (p=0.03). Comparison of average drowsiness scores between the two groups of participants based on Mann-Whitney test showed no significant difference (p>0.005). Chi square test showed a significant difference between severity of drowsiness and type of working shift (p =0.028 and 0.009). Staff in revolving shifts suffers poor sleep quality comparing with staff with fixed working shift. Moreover, type of working shift greatly affects severity of drowsiness as staff at different work shift experienced different level of sleepiness. It is essential to survey sleep disorder of the staff in the industry and pay more emphasis on sleep disorder epidemic in other fields of industry.

About 20% of workers in industrialized countries are shift workers and more than half of them work on night or rotating shifts. Most night workers complain of sleepiness due to lack of adjustment of the circadian rhythm. In simulated night-work experiments, scheduled exposure to bright light has been shown to reduce these complaints. Our study assessed the effects of bright light exposure on sleepiness during night work in an industrial setting. In a cross-over design, 94 workers at a ceramic factory were exposed to either bright (2500 lux) or normal light (300 lux) during breaks on night shifts. We initiated 20-minute breaks between 24.00 and 02.00 hours. Sleepiness ratings were determined using the Stanford Sleepiness Scale at 22.00, 24.00, 02.00 and 04.00 hours. Under normal light conditions, sleepiness peaked at 02:00 hours. A significant reduction (22% compared to normal light conditions) in sleepiness was observed after workers were exposed to bright light. Exposure to bright light may be effective in reducing sleepiness among night workers.

To evaluate pulmonary function and respiratory symptoms in workers engaged in the early manufacturing processes of tea and to identify the associated factors, we conducted a study in a tea production area in Taiwan. We recruited tea workers who engaged in the early manufacturing process in the Mountain Ali area in Taiwan and a comparison group of local office workers who were matched for age, gender, and smoking habits. We performed questionnaire interviews, pulmonary function tests, skin prick tests, and measurement of specific IgE for tea on the participants and assessed tea dust exposures in the tea factories. The 91 participating tea workers had higher prevalence of respiratory symptoms than the comparison group (32 participants). Among tea workers, ball-rolling workers had the highest prevalence of symptoms and the highest exposures of inhalable dusts. At baseline, tea workers had similar pulmonary functions as the comparison group, but compared to the other tea workers ball-rolling workers had a lower ratio of the 1-second forced expiratory volume to forced vital capacity (FEV1/FVC) and a lower maximal mid-expiratory flow rate expressed as% of the predicted value--MMF (%pred). A total of 58 tea workers participated in the on-site investigation and the cross-shift lung function measurements. We found ball-rolling yielded the highest inhalable dust level, panning yielded the highest respirable dust level, and withering yielded the lowest levels of both dusts. Ball-rolling also yielded the highest coarse fraction (defined as inhalable dusts minus respirable dusts), which represented exposures from nose to tracheobronchial tract. During the shift, we observed significant declines in pulmonary function, especially in ball-rolling workers. Multiple regressions showed that age, height, work tasks, coarse fraction, and number of months working in tea manufacturing each year were independent predictors of certain pulmonary function parameters in tea workers. Tea workers engaged in early manufacturing processes of tea have higher prevalence of respiratory symptoms and pulmonary function impairment, which might be related to tea dust exposures, especially the coarse fraction.

Determination of crystalline silica in respirable dust upon occupational exposure for Egyptian workers

Crystalline free silica is considered as a lung carcinogen and the occupational exposure to its dust is a health hazard to workers employed in industries that involve ores of mineral dust. In Egypt, thousands of people work under conditions of silica dust exposure exceeding the occupational exposure limit, as a result the monitoring of this occupational exposure to crystalline silica dust is required by government legislation. The assessment of the later is a multi-phase process, depend on workplace measurements, quantitative analyses of samples, and comparison of results with the permissible limits. This study aims to investigate occupational exposure to crystalline silica dust at 22 factories in Egypt with different industrial activities like stone cutting, glass making, ceramic, and sand blasting. Dust samples were collected from work sites at the breathing zone using a personal sampling pump and a size-selective cyclone and analyzed using FTIR. The sampling period was 60–120 min. The results show that the exposure at each of the industrial sectors is very much higher than the current national and international limits, and that lead to a great risk of lung cancer and mortality to workers.

An analysis has been made of the mortality and cancer incidence of 1168 workers who entered the three factories of the perfumery industry of the Canton of Geneva from their establishment at the turn of the century to the end of 1964. The workers were followed up from their entry until 31 December 1980, at which date 344 were dead and 28 lost to follow up. Among the whole study population only mortality from tuberculosis was significantly raised; there was no significant increase in the incidence of or mortality from any cancer. Analysis by four exposure categories showed a significant excess of deaths from heart disease among the compounders. In addition, two deaths from aplastic anaemia were recorded in chemical process workers exposed to benzene. Further analysis by cohort of entry and by birth cohort indicated that, among the subgroup of men first employed in 1900-29 and born in 1880-99, the mortality from a wide range of causes was significantly increased below the age of 70. This increase is unlikely to be due to an occupational factor as indicated by the absence of an upward trend of mortality with longer exposure. PMID:3978043

Knowledge about breastfeeding among women is very important for healthy children. The present study aims to determine the level of knowledge and factors associated with knowledge on breastfeeding among female garment workers in a selected garment factory in Dhaka city. A cross-sectional study was conducted among 200 female garment workers in the reproductive age group (15-49 years). Data were collected through a pre-tested questionnaire using the face-to-face interview method. Bivariate and multivariate analysis was done to determine the association between sociodemographic variables and knowledge on breastfeeding. The study showed that, overall the level of knowledge regarding breastfeeding is very poor (88%) among the study subjects. Most of the respondents have very poor knowledge regarding advantages of exclusive breastfeeding (89%) and breastfeeding (100%). In contrast, a majority have good knowledge on duration of exclusive breastfeeding (74%) and breastfeeding (66%). No significant association was found between the knowledge score of breastfeeding with remaining socio-demographic variables like age, marital status, family income and expenditure. Education is significantly (p<0.001) associated with a higher total knowledge score of breastfeeding. Women with secondary level of education had a significantly higher (p<0.001) level of total knowledge score than other categories (illiterate, primary and higher secondary) of education. A large proportion of female garment workers had inadequate knowledge regarding breastfeeding. It is also important that health education on breastfeeding is urgently provided to the female garments workers of Bangladesh.

Polycyclic aromatic hydrocarbons exposure (PAHs: (benz[a]anthracene, benzo[a]pyrene, dibenz[a,h]anthracene, benzo[b]fluoranthene, benzo[k]fluoranthene, indeno[1,2,3-cd]-pyrene, fluoranthene, chrysene, pyrene) of policemen on street duty in downtown Budapest and workers repairing the road (asphalting) at a traffic junction and their excretion of PAH metabolites (1-hydroxypyrene, 3-hydroxybenz[a]anthracene, and 3-hydroxybenzo[a]pyrene) were determined. As controls, health-care workers were investigated. In addition PAH pollution of the air of a factory processing asphalt was also measured. The measurements were performed on air samples gained using personal samplers and from urine of end-shift samples using a high-performance liquid chromatography method. It was found that PAH pollution of the most crowded and busy center of Budapest was similar to that of several other cities in the world. PAH exposure of road builders was actually not higher than that of policemen; the slight difference resulted from diverging life-styles. PAH metabolite excretion of smoking health-care workers, road builders, or policemen significantly exceeded that of the nonsmokers. The PAH metabolite values of the three groups engaged in various activities did not show any difference. It was concluded that cancer-related risk due to PAH compounds in the case of policemen on street duty and road builders (asphalting) does not exceed significantly that of workers not exposed occupationally to PAHs in the ambient air, but that smoking is a decisive factor.

To monitor the occurrence of cancer in a recently defined cohort of UK rubber workers. A cohort of 8651 male and female workers from 41 UK rubber factories has been enumerated. All employees had a minimum of 12 months employment and were first employed at one of the participating factories in the period 1982-91. Mortality and cancer incidence data for the period 1983-2004 were compared with expected values based on appropriate national rates. Mortality from lung cancer was close to expectation for males [observed 22, standardized mortality ratio (SMR) 93] and females (observed 2, SMR 70). Mortality from stomach cancer was also unexceptional in males (observed 4, SMR 86) and females (observed 0, SMR 0). Although based on small numbers, significantly elevated mortality was shown for multiple myeloma in males (observed 5, SMR 385) and females (observed 2, SMR 952). All seven of these latter deaths occurred in workers from the general rubber goods (GRG) sector. The findings should be treated with caution as they relate to a relatively early period of follow-up. Nevertheless, they hold out the prospect that the elevated SMRs for stomach and lung cancers reported for historical cohorts of UK rubber workers will not be present in more recent cohorts. The elevated occurrence of multiple myeloma may represent no more than a chance finding. Alternatively, these findings may reflect the presence of an unrecognized occupational cancer hazard in parts of the GRG sector of the UK rubber industry.

Argan is used worldwide in numerous cosmetic products, as this fruit is supposed to have many beneficial properties on health. New cases of allergy can be expected with the growing use of argan. We investigated all workers (9) employed by a cosmetic factory and exposed to argan powder to identify possible allergies related to exposure to argan powder. Patients were investigated in the occupational disease department and, according to their symptoms, underwent pulmonary function testing, methacholine challenge, specific inhalation challenge to argan powder, skin prick tests, and immunoblotting analysis. We report three cases of occupational asthma to argan powder and a probable case of rhinitis. Fifteen argan proteins were recognized by the patients' IgE. Identification of proteins, cross-reactions to nuts, and ELISA inhibition tests suggested that some argan allergens can cross-react in vitro with hazelnut allergens, including 11S globulin and vicilin. High-level exposure to argan powder should be considered to be a potential cause of IgE-mediated allergy, and workers handling argan powder should be carefully investigated. © 2015 John Wiley & Sons A/S.

The Médecins Sans Frontiérs (MSF) established basic occupational health services to diagnose and treat work-related diseases among tannery, metal, plastics and garment workers and families in one of the more polluted areas of the world populated by 600 000 people. In spite of project limitations, an analysis of the 6-month data showed that of the original cohort of 5000, 3200 (64%) came for at least 1 consultation. Among them, 468 (14.6%) were diagnosed with suspected work-related diseases as per defined protocols. Follow-up consultation was performed for 1447 cases of occupational diseases and work-related injuries. The MSF experience begs the need for replication of such services in densely populated urban areas in developing nations like Bangladesh and India, where no specialty occupational health clinics exist in primary care but are desperately needed and where occupational health clinics on factory premises are exclusive to industry workers and are not accessible to communities. 2017 BMJ Publishing Group Ltd.

1987-01-01

Three workers from a color printing factory were admitted to community hospitals in 1985 with manifestations of acute hepatitis. One of the three had superimposed acute renal failure and pulmonary edema. An investigation was subsequently conducted at the plant to determine the etiology of the outbreak and the prevalence of liver disease among the remaining workers. Comprehensive medical evaluations were conducted, which included physical examinations, liver function tests, and serological screening for hepatitis. Seventeen of 25 workers from the plant had abnormal liver function tests 10 days after the outbreak, and a significant association was found between the presence of abnormal liver function tests and a history of recently having worked inside any of three rooms in which an interconnecting air conditioning system had been installed to cool the printing machines. After further investigation, it was determined that the incident occurred following inadvertent use of carbon tetrachloride to clean a pump in the printing machine. A simulation of the pump cleaning operation revealed ambient air levels of carbon tetrachloride of 300-500 ppm. Ultimately, it was concluded that the outbreak was in all likelihood due to the combined use of carbon tetrachloride and isopropyl alcohol in the cleaning operation. This outbreak underscores the importance of adopting appropriate industrial hygiene measures in a rapidly industrializing nation such as Taiwan.

The aim of this study was to assess cancer incidence in a cohort of woodworkers exposed to softwood dust in a Lithuanian wooden joinery products factory. The study population consisted of 1518 workers (1080 men and 438 women) employed in the factory for at least 1 year between 1947 and 1996 and living in Lithuania on 1 January 1978, when the follow-up for cancer incidence began. The follow-up period for cancer was 1978-2007. Cancer risk was assessed by standardised incidence ratios (SIR) with reference to the national population. Overall cancer incidence was not increased among woodworkers. However, the number of mouth and pharynx cancer cases among male woodworkers was significantly increased compared with expected numbers (SIR 2.19, 95% CI 1.17 to 3.74). A higher risk was found for cancer of the buccal cavity than for pharyngeal cancer (SIRs 2.83 and 1.45, respectively). The SIR for larynx cancer was also elevated (SIR 1.39, 95% CI 0.64 to 2.64) among men, while the number of lung cancer cases was higher than expected only among women (SIR 2.07, 95% CI 00.57 to 5.31). This results of this study support the hypothesis that exposure to softwood dust may increase the risk of oral and pharyngeal cancer. No support was found for an increased risk of other respiratory cancers among workers exposed to softwood dust.

To assess wood dust exposures and determinants in joineries and furniture manufacturing and to evaluate the efficacy of specific interventions on dust emissions under laboratory conditions. Also, in a subsequent follow-up study in a small sample of joinery workshops, we aimed to develop, implement, and evaluate a cost-effective and practicable intervention to reduce dust exposures. Personal inhalable dust (n = 201) was measured in 99 workers from 10 joineries and 3 furniture-making factories. To assess exposure determinants, full-shift video exposure monitoring (VEM) was conducted in 19 workers and task-based VEM in 32 workers (in 7 joineries and 3 furniture factories). We assessed the efficacy of vacuum extraction on hand tools and the use of vacuum cleaners instead of sweeping and dry wiping under laboratory conditions. These measures were subsequently implemented in three joinery workshops with 'high' (>4 mg m-3) and one with 'low' (<2 mg m-3) baseline exposures. We also included two control workshops (one 'low' and one 'high' exposure workshop) in which no interventions were implemented. Exposures were measured 4 months prior and 4 months following the intervention. Average (geometric means) exposures in joinery and furniture making were 2.5 mg m-3 [geometric standard deviations (GSD) 2.5] and 0.6 mg m-3 (GSD 2.3), respectively. In joinery workers cleaning was associated with a 3.0-fold higher (P < 0.001) dust concentration compared to low exposure tasks (e.g. gluing), while the use of hand tools showed 3.0- to 11.0-fold higher (P < 0.001) exposures. In furniture makers, we found a 5.4-fold higher exposure (P < 0.001) with using a table/circular saw. Laboratory efficiency experiments showed a 10-fold decrease in exposure (P < 0.001) when using a vacuum cleaner. Vacuum extraction on hand tools combined with a downdraft table reduced exposures by 42.5% for routing (P < 0.1) and 85.5% for orbital sanding (P < 0.001). Following intervention measures in joineries, a borderline statistically significant (P < 0.10) reduction in exposure of 30% was found in workshops with 'high' baseline exposures, but no reduction was shown in the workshop with 'low' baseline exposures. Wood dust exposure is high in joinery workers and (to a lesser extent) furniture makers with frequent use of hand tools and cleaning being key drivers of exposure. Vacuum extraction on hand tools and alternative cleaning methods reduced workplace exposures substantially, but may be insufficient to achieve compliance with current occupational exposure limits. © The Author 2017.

Although a large number of contributing factors of occupational injury causation are explored meticulously to explain the phenomenon of higher occupational injury occurrence in some subjects, it has remained a matter of controversy. In this study, an effort is made to explore whether job security has any contribution in explaining higher susceptibility of some workers. This was a retrospective occupational injury record study conducted in an industry of eastern India. Along with the study of injury records of 5 years, an interview was also conducted involving 726 workers (including permanent and temporary workers both) of the factory. Comparison was made between permanent and temporary workers by using the Mann-Whitney U-test and the chi-square test. A theoretical model of Poisson's distribution was used to compare between expected and real occurrence. Although two worker groups were very similar in relation to age, level of education, habits, and nature of work, accident frequency and severity rates were found to be significantly higher in temporary workers. This study concluded that the higher accident risk of the temporary workers might have been due to the less effective experience as well as due to lack of job security inherent in such workers.

Apart from the use of vibrating tools, little is known about risk factors for Raynaud's phenomenon. However, it has been hypothesized that this disorder may have a multifactorial aetiology, involving potential causal or triggering factors which can be found in the workplace. The objective of the study is to identify individual and occupational risk factors of Raynaud's phenomenon in a population of workers not exposed to vibration, but exposed to cold. The survey was carried out in 1987-1988 in 17 poultry slaughterhouses and six canning factories and included 1474 employees. Data were collected at the annual visit to the occupational health physician. Finger sensitivity to cold and Raynaud's phenomenon were identified from a list of symptoms occurring from exposure to cold. The role of potential risk factors was assessed using multiple logistic regression. A high prevalence of symptoms of finger sensitivity to cold was observed. Raynaud's phenomenon was more common in women than in men, was related to family history of the disease but not to smoking or alcohol consumption. After controlling for non-occupational factors, the following working conditions appeared as risk factors for Raynaud's phenomenon: use of plastic gloves, less than four rest breaks, breaks in an unheated place, continual repetition of the same series of operations, exertion of the arm or hand and being able to think of something else while working. The study showed that a number of working conditions were associated with an increased risk of Raynaud's phenomenon and finger sensitivity to cold. Changes in working conditions might reduce the risk of this disorder in the food processing industry.

Objectives: This paper investigates determinants of wood dust exposure and trends in dust level in the furniture industry of Viborg County, Denmark, using data from two cross-sectional studies 6 years apart. Methods: During the winter 1997/1998, 54 factories were visited (hereafter study 1). In the winter 2003/2004, 27 factories were revisited, and personal dust measurements were repeated. In addition, 14 new factories were included (hereafter study 2). A total of 2303 woodworkers participated in study 1, and 2358 measurements from 1702 workers were available. From study 2, 1581 woodworkers participated and 1355 measurements from 1044 workers were available. Information on occupational variables describing potential determinants of exposures like work task, exhaust ventilation, enclosure and cleaning procedures were collected. A total of 2627 measurements and 1907 persons were included in the final mixed model in order to explore determinants of exposure and trends in dust level. Results: The overall inhalable wood dust concentration (geometric means (geometric standard deviation)) has decreased from 0.95 mg/m3 (2.05) in study 1 to 0.60 mg/m3 (1.63) in study 2, representing a 7% annual decrease in dust concentration, which was confirmed in the mixed model. From study 1 to study 2 there has been a change towards less manual work and more efficient cleaning methods, but on the contrary also more inadequate exhaust ventilation systems. The following determinants were found to ‘increase’ dust concentration: sanding; use of compressed air; use of full-automatic machines; manual work; cleaning of work pieces with compressed air; kitchen producing factories and small factories (<20 employees). The following determinants of exposure were found to ‘decrease’ dust concentration: manual assembling/packing; sanding with adequate exhaust ventilation; adequate exhaust ventilation; vacuum cleaning of machines and special cleaning staff. Conclusions: Despite a substantial drop in the dust concentration during the last 6 years in the furniture industry in Viborg County, further improvements are possible. There should be more focus on improved exhaust ventilation, professional cleaning methods and avoiding use of compressed air. PMID:18407937

The objectives of this study were to develop a questionnaire that evaluates the perception of nursing workers to job factors that may contribute to musculoskeletal symptoms, and to evaluate its psychometric properties. Internationally recommended methodology was followed: construction of domains, items and the instrument as a whole, content validity, and pre-test. Psychometric properties were evaluated among 370 nursing workers. Construct validity was analyzed by the factorial analysis, known-groups technique, and convergent validity. Reliability was assessed through internal consistency and stability. Results indicated satisfactory fit indices during confirmatory factor analysis, significant difference (p < 0.01) between the responses of nursing and office workers, and moderate correlations between the new questionnaire and Numeric Pain Scale, SF-36 and WRFQ. Cronbach's alpha was close to 0.90 and ICC values ranged from 0.64 to 0.76. Therefore, results indicated that the new questionnaire had good psychometric properties for use in studies involving nursing workers. Copyright © 2014 Elsevier Ltd and The Ergonomics Society.

Organized labor and the origins of the Occupational Safety and Health Act.

Asher, Robert

2014-11-01

New Solutions is republishing this 1991 article by Robert Asher, which reviews the history of organized labor's efforts in the United States to secure health and safety protections for workers. The 1877 passage of the Massachusetts factory inspection law and the implementation of primitive industrial safety inspection systems in many states paralleled labor action for improved measures to protect workers' health and safety. In the early 1900s labor was focusing on workers' compensation laws. The New Deal expanded the federal government's role in worker protection, supported at least by the Congress of Industrial Organizations (CIO), but challenged by industry and many members of the U.S. Congress. The American Federation of Labor (AFL) and the CIO backed opposing legal and inspection strategies in the late 1940s and through the 1950s. Still, by the late 1960s, several unions were able to help craft the Occupational Safety and Health Act of 1970 and secure new federal protections for U.S. workers.

Respiratory diseases cause a considerable amount of morbidity and mortality in the world. Pulmonary function tests are important measures for the diagnosis and management of respiratory disorders. Workers in tile and ceramic industry are exposed to high amounts of respiratory pollutants. To identify the changes in spirometric parameters in a 2-year period among tile and ceramic workers in Yazd and compare it with a control group. The study was conducted in 5 tile and ceramic factories selected by cluster sampling between 2009 and 2011 in Yazd, southeastern Iran. Demographic data and spirometric parameters of participants were recorded. Spirometric parameters were significantly reduced during the 2 years. The largest decrease was observed in FVC (≈500 mL) in ball-mill and grinding after 2 years. Decrease in all spirometric parameters was significantly higher in industrial workers than office workers. Respiratory exposure in tile and ceramic industry can significantly affect pulmonary function tests.

Guidelines on Thermal Comfort of Air Conditioned Indoor Environment

NASA Astrophysics Data System (ADS)

Miura, Toyohiko

The thermal comfort of air conditioned indoor environment for workers depended, of course, on metabolic rate of work, race, sex, age, clothing, climate of the district and state of acclimatization. The attention of the author was directed to the seasonal variation and the sexual difference of comfortable temperature and a survey through a year was conducted on the thermal comfort, and health conditions of workers engaged in light work in a precision machine factory, in some office workers. Besides, a series of experiments were conducted for purpose of determinning the optimum temperature of cooling in summer time in relation to the outdoor temperature. It seemed that many of workers at present would prefer somewhat higher temperature than those before the World War II. Forty years ago the average homes and offices were not so well heated as today, and clothing worn on the average was considerably heavier.

The food and agriculture industry employs 14.6% of the female industrial work force in France. Workers are exposed to a variety of environmental and organizational constraints (eg, irregular schedules, cold, uncomfortable postures, repetitive movements). In 1987-1988 a medical examination and questionnaire were administered to 726 workers with menstrual periods in 17 poultry slaughterhouses and six canning factories. Anomalies (irregular cycles, amenorrhea, long cycles) during the previous year were associated with work conditions. After adjustment for relevant nonoccupational variables, irregular cycles were significantly related to schedule variability and cold exposure, amenorrhea was associated with cold exposure, and long cycles with schedule variability. Other parameters such as repetitive work, standing posture, lifting weights, job satisfaction, and hours of domestic work were not associated with cycle anomalies. Cycle anomalies may be a useful indicator of occupational effects on female reproduction, analogous to the use of sperm parameters to warn of effects on male workers.

A case-control interview study on 610 lung cancer patients and 959 controls was conducted among male workers in Anshan Iron-steel Complex. After adjusting for non-occupational risk factors, such as smoking, pulmonary disease, family history of cancer and the consumption of fruit, risks for lung cancer were significantly higher in workers engaged in smelting and rolling (OR = 1.5, 95% CI = 1.1-2.2), in the fire-resistant brick factory (OR = 2.9, 95% CI = 1.4-5.9), in general loading (OR = 2.5 95% CI = 1.0-6.1), and in coking (OR = 3.4, 95% CI = 1.4-8.5) for 15 or more years. Significant dose-response was observed for exposure to total dust and B[a]P, but not for specific chemical components of dust. The lung cancer risk increased 40% in iron and steel workers with long term occupational exposure.

This article describes a particular way developed by employees to respond to the constraints of a very restrictive manufacturing plant: the mutual cooperation. Facing a very strict organizational context, the production workers can only rely on themselves to cope with the constraints of work. In this context, a complex system of strategies is deployed, resulting in a work environment governed by the sense of collaboration and mutual cooperation. The objectives of the implemented strategies, however, go beyond the attempts to reduce the work overload. They may be linked to a way of maintaining high levels of productivity and a way for workers to keep their jobs. We hope to contribute, through this study, to the general knowledge of the strategies developed by workers in production lines in order to minimize the pains.

OBJECTIVES: Little information is available on the quantitative risks of respiratory disease from quartz in airborne dust in the heavy clay industry. Available evidence suggested that these risks might be low, possibly because of the presence in the dust of other minerals, such as illite and kaolinite, which may reduce the harmful effects of quartz. The aims of the present cross sectional study were to determine among workers in the industry (a) their current and cumulative exposures to respirable mixed dust and quartz; (b) the frequencies of chest radiographic abnormalities and respiratory symptoms; (c) the relations between cumulative exposure to respirable dust and quartz, and risks of radiographic abnormality and respiratory symptoms. METHODS: Factories were chosen where the type of process had changed as little as possible during recent decades. 18 were selected in England and Scotland, ranging in size from 35 to 582 employees, representing all the main types of raw material, end product, kilns, and processes in the manufacture of bricks, pipes, and tiles but excluding refractory products. Weights of respirable dust and quartz in more than 1400 personal dust samples, and site histories, were used to derive occupational groups characterised by their levels of exposure to dust and quartz. Full size chest radiographs, respiratory symptoms, smoking, and occupational history questionnaires were administered to current workers at each factory. Exposure-response relations were examined for radiographic abnormalities (dust and quartz) and respiratory symptoms (dust only). RESULTS: Respirable dust and quartz concentrations ranged from means of 0.4 and 0.04 mg.m-3 for non-process workers to 10.0 and 0.62 mg.m-3 for kiln demolition workers respectively. Although 97% of all quartz concentrations were below the maximum exposure limit of 0.4 mg.m-3, 10% were greater than this among the groups of workers exposed to most dust. Cumulative exposure calculations for dust and quartz took account of changes of occupational group, factory, and kiln type at study and non-study sites. Because of the importance of changes of kiln type additional weighting factors were applied to concentrations of dust and quartz during previous employment at factories that used certain types of kiln. 85% (1934 employees) of the identified workforce attended the medical surveys. The frequency of small opacities in the chest radiograph, category > or = 1/0, was 1.4% (median reading) and seven of these 25 men had category > or = 2/1. Chronic bronchitis was reported by 14.2% of the workforce and breathlessness, when walking with someone of their own age, by 4.4%. Risks of having category > or = 0/1 small opacities differed by site and were also influenced by age, smoking, and lifetime cumulative exposure to respirable dust and quartz. Although exposures to dust and to quartz were highly correlated, the evidence suggested that radiological abnormality was associated with quartz rather than dust. A doubling of cumulative quartz exposure increased the risk of having category > or = 0/1 by a factor of 1.33. Both chronic bronchitis and breathlessness were significantly related to dust exposure. CONCLUSIONS: Although most quartz concentrations at the time of this study were currently below regulatory limits in the heavy clay industry, high exposures regularly occurred in specific processes and occasionally among most occupational groups. However, there are small risks of pneumoconiosis and respiratory symptoms in the industry, although frequency of pneumoconiosis is low in comparison to other quartz exposed workers.   PMID:10448318

Brucellosis is an occupational disease affecting workers in butcher shops, the milking and dairy product industry, causing more than 500 000 new cases around the world. As a national statutory B infectious disease in China, morbidity of brucellosis is rapidly increasing in recent years. We report an occupational outbreak of brucellosis infection in a pharmaceutical factory. Exposure was a result of manual operation in the process line, close contact with sheep placentas, insufficient disinfection and repeated using of protective suits and infected by aerosol dissemination. Improved preventive methods, appropriate public health measures and spread of health education would be helpful to prevent the occupational outbreak of brucellosis in future. © 2016 Blackwell Verlag GmbH.

Coke oven workers are regularly exposed to polycyclic aromatic hydrocarbons (PAHs). Benzo[a]pyrene (B[a]P), known as an indicator species for PAH contamination, is a neurobehavioral toxicant. The purpose of the study was to evaluate the relationship between B[a]P exposure, a B[a]P-related urinary metabolite and neurobehavioral function among coke oven workers. Coke oven workers and oxygen factory workers participated in this study. B[a]P exposure was monitored by air sampling pump, and urinary 1-hydroxypyrene (1-OHP) level was detected with high performance liquid chromatography (HPLC). A questionnaire and the neurobehavioral core test battery (NCTB) were administered to all subjects. B[a]P-exposed workers were found to have higher urinary 1-OHP levels and worse NCTB performances on eight items than control workers. B[a]P concentrations were higher in the coke oven plant than that in the controls' workplace. The performances on simple reaction time, correct pursuit aiming, and error pursuit aiming decreased with increasing airborne B[a]P in coke oven workers. There were significant correlations between urinary 1-OHP level and six items of the NCTB. Occupational exposure to B[a]P is associated with neurobehavioral function impairment in coke oven workers.

Two cases of paraoccupational asthma due to toluene diisocyanate (TDI).

PubMed

De Zotti, R; Muran, A; Zambon, F

2000-12-01

Two cases of paraoccupational asthma caused by toluene diisocyanate (TDI) are reported. The first patient was a metal worker in a machine shop situated near a factory producing polyurethane foam. Symptoms at work were not explainable by any specific exposure to irritants or allergens in the work site. As the patient recalled previous occasional work in the adjacent polyurethane factory with accompanying worsening of respiratory symptoms, a specific inhalation (SIC) test was performed with TDI, which confirmed the diagnosis of TDI asthma. The second case was a woman working part time as a secretary in the offices of her son's factory for varnishing wooden chairs. TDI was present in the products used in the varnishing shed. The SIC test confirmed the diagnosis of TDI asthma, despite the fact that the patient's job did not present risk of exposure to the substance. In both patients, symptoms disappeared when further exposure was avoided. These two cases confirm that paraoccupational exposure to TDI must be considered when evaluating patients with asthma not mediated by immunoglobulin E. They also suggest the need for more prospective studies evaluating the health risk for the general population living near polyurethane factories or other firms that use TDI.

Relationship between blood lead level and work related factors using the NIIH questionnaire system.

Saito, Hiroyuki; Mori, Ippei; Ogawa, Yasutaka; Hirata, Mamoru

2006-10-01

Over an 11-yr period (1990-2000), a questionnaire survey on work environmental management and environmental improvement was conducted on 259 lead-handling factories and 7,623 subjects. Labour Inspection Offices identified these factories as requiring environmental improvement, or possessing a desire to improve their working environment. We analyzed factors affecting blood lead levels (PbBs). These factors were gender, age, employment duration, factory size, work environment control (WEC) class, and job categories. The PbB of men was found to be higher than that of women, and may be due to the differences in job distribution. PbB increased along with increasing age and employment duration. PbB declined as the factory size increased. The odds ratio (OR) of PbB higher than 20 microg/dl according to factory size was significantly high even after adjusting for WEC class. This demonstrates that not only the working environment but also safety management was poorer among small-scale factories that large-scale factories. The rise of PbB along with the increase of WEC class confirmed that the results of work environment measurement are correlated with individual exposure levels. The risk of having a 20 microg/dl or higher PbB was different for various lead handling jobs. Smelting or refining lead had the highest risk for lead exposure while painting or baking had the lowest risk. As our study population was not a randomly selected sample, we are unable to generalize our results for workers across Japan. However, we were able to indicate which jobs pose a high-risk and the effectiveness of using the work environment control class as an index of worksite environment levels.

Using chromium and nickel for electroplating is important in many industries. This process induces variable adverse health effects among exposed workers. The aim of this study is to detect the genotoxic effects of combined exposure to chromium and nickel among electroplating workers. This study was conducted on 41 male workers occupationally exposed to chromium and nickel in the electroplating section of a factory compared to 41 male nonexposed individuals, where full history and clinical examination were performed. Laboratory investigations included measurement of serum chromium, nickel, 8-hydroxydeoxyguanosine (8-OHdG), and micronuclei were measured in buccal cells. In exposed workers, serum chromium ranged from 0.09 to 7.20 µg/L, serum nickel ranged from 1.20 to 28.00 µg/L, serum 8-OHdG ranged from 1.09 to12.60 ng/mL, and these results were statistically significantly increased compared to nonexposed group ( P < 0.001). Electroplaters showed higher frequencies of micronuclei in buccal cells when compared to nonexposed (ranged from 20.00 to 130.00 N/1,000 versus 2.00 to 28.00 N/1,000; P < 0.001). Linear regression models were done to detect independent predictors of 8-OHdG and micronucleus test by comparing exposed and nonexposed groups. The model found that exposure to chromium and nickel increases serum 8-OHdG by 4.754 (95% confidence interval [CI]: 3.54-5.96). The model found that exposure to chromium and nickel increases micronucleus by 35.927 (95% CI: 28.517-43.337). Serum 8-OHdG and micronucleus test in buccal cells were increased with combined exposure to chromium and nickel. The current research concluded that workers exposed to nickel and chromium in electroplating industry are at risk of significant cytogenetic damage.

An ergonomics intervention program (EIP) was conducted with male employees working in the pressing and storage sections of a metal autoparts factory in Samut Prakan Province, Thailand. The objectives of this study were to assess the causes of injuries in the pressing and storage sections of that factory, and to improve working conditions by reducing worker injuries from accidents and low back muscular discomfort, using an EIR The study design used a participatory research approach which was quasi-experimental with pretest-posttest evaluations, with a non-equivalent control group. A total of 172 male participants working in Building A were the target group for assessing causes of injury. A retrospective study of official accident information, and questionnaires for general information, health and muscular discomfort, injury frequency rate (IFR), injury severity rate (ISR), medical expenses, and EIP design. Two groups of employees volunteered for the study on muscular back discomfort. The first group of 35 persons volunteered to participate in the EIP (EIP group), and the second 17 persons from Building B did not (non-EIP group). The EIP was composed of 4 major categories: (1) engineering improvement, (2) change in personal protective equipment, (3) environmental improvement, (4) administrative intervention, training, and health education. Low back muscular discomfort was measured through questionnaires on subjective feelings of muscular discomfort, and by surface electromyography (sEMG). Muscle activities were measured by sEMG of the left and right erector spinae and multifidus muscles, and evaluated by multivariate test for dependent samples (paired observation), and multivariate test for two independent samples. After EIP, IFR decreased 65.46%, ISR decreased 41.02%, and medical expenses decreased 42.79%. The low back muscular loads of the EIP group were significantly reduced, with a 95% confidence level (p < 0.05) while those of the non-EIP group were not. Subjective feelings of muscular discomfort, determined by Wilcoxon Signed Ranks test, showed that after applying the EIP to the EIP group, the mean scores for general bodily discomfort and low back muscular discomfort in the EIP group had significantly reduced, while those of the non-EIP group increased, (p < 0.05).

Between September 17 and October 3, 2009, hundreds of workers employed in a manufacturing factory in Shenzhen, a city in south China developed a sudden onset of acute gastroenteritis. A retrospective cohort study is designed to identify the risk factors and control this outbreak. Information on demographic characteristics, working place, the history of contact with a person having diarrhea and/or vomiting, drink water preference and frequency, eating in the company cafeteria or outside the company, hand-washing habits and eating habits is included. Furthermore, in order to find the contamination source, we investigated the environment around the underground reservoir and collected water samples from the junction between municipal supply water system and underground reservoir to test potential bacteria and virus, examine the seepage tracks on the wall of the underground reservoir from the side of septic tank, and check the integrity and attitude of this lid. Relative risk was presented and Chi-square test was performed. All the analyses were performed with OpenEpi software version 2.3.1 online. The cohort study demonstrated that the workers who had direct drink water were 3.0 fold more likely to suffer from acute gastroenteritis than those who consumed commercial bottled water. The direct drinking water, water of the tank of buildings, and the underground reservoir were positive only for norovirus. Norovirus was also detected from stool and rectal swab samples from patients with acute gastroenteritis. The underground reservoir was found to be the primary contamination source. Further environmental investigation showed that the norovirus contaminated substance entered into the underground reservoir via access holes in lid covering this underground reservoir. This acute gastroenteritis outbreak was caused by the secondary supply system contaminated by norovirus in this factory. The outbreak of gastroenteritis cases caused by norovirus frequently occurred in China due to a lack of surveillance and supervision, and due to faults in the construction of such water systems. Therefore, more attentions should pay to the secondary supply water system in China.

To investigate the relationship between genetic polymorphism of X-ray repair cross-complementing gene 3 (XRCC3) and susceptibility to lead poisoning in male lead-exposed workers. Peripheral venous blood and morning urine samples were collected from 326 male lead-exposed workers in a storage battery factory in Fuzhou. Blood lead, urine lead, blood zinc protoporphyrin (ZPP), blood calcium, and blood iron were measured. The genotype of XRCC3 was determined by polymerase chain reaction-restriction fragment length polymorphism method. The relationship between XRCC3 gene polymorphism and susceptibility to lead poisoning in male lead-exposed workers was analyzed. Genetic polymorphism of XRCC3 was seen in the 326 subjects. The frequency distribution of XRCC3 genotypes, XRCC3-241CC (wild type), XRCC3-241CT (heterozygous mutation), and XRCC3-241TT (homozygous mutation), was in accordance with the Hardy-Weinberg equilibrium (P > 0.05). There were no significant differences in urine lead, blood ZPP, blood calcium, and blood iron between the lead-exposed workers with different XRCC3 genotypes (P > 0.05). The workers with XRCC3-241CT/TT had a significantly higher mean blood lead level than those with XRCC3-241CC (P < 0.05). With a blood lead level of 1.90 µmol/L as the cutoff value, the chi-square test and logistic regression analysis showed that the proportion of workers with XRCC3-241CT/TT was significantly higher than that of workers with XRCC3-241CC in the subjects with high blood leads (P < 0.05) and that the risk of high blood lead was significantly higher in the workers with XRCC3-241CT/TT than in those with XRCC3-241CC (OR = 2.34, 95%CI = 1.61 ∼ 5.13); the multivariate linear regression analysis showed that the workers with XRCC3-241CT/TT had high blood lead levels (β = 0.116, P < 0.05), the workers with smoking habit demonstrated marked lead absorption (β = 0.188, P < 0.05), good individual protection could reduce lead absorption (β = -0.247, P < 0.05), and the individuals with low serum Ca²⁺ levels had high blood lead levels (β = -0.145, P < 0.05). When exposed to the same level of lead at workplace, the workers with XRCC3-241CT/TT have a significantly higher blood lead level than those with XRCC3-241CC, so the genotype of XRCC3-241CT/TT accounts for higher susceptibility to lead poisoning.

To evaluate sensitization to chemicals present in work environment after an outbreak of contact dermatitis in workers of vehicle equipment factory, exposed to polyurethane foam, based on 4,4'-diphenylmethane diisocyanate (MDI). From among 300 employees, 21 individuals reporting work-related skin and/or respiratory tract symptoms underwent clinical examination, patch testing, skin prick tests, spirometry and MDI sIgE measurement in serum. Patch tests included isocyanates series, selected rubber additives, metals, fragrances, preservatives, and an antiadhesive agent. Clinical examination revealed current eczema in the area of hands and/or forearms in 10 workers. Positive patch test reactions were found in 10 individuals, the most frequent to diaminodiphenylmethane and 4-phenylenediamine (7 persons). Reactions to an antiadhesive agent were assessed as irritant (5 workers). Except for sensitization to common aeroallergens, no significant abnormalities were found in the remaining tests. Occupational allergic contact dermatitis was diagnosed in 7 workers, irritant contact dermatitis in 10 and coexisiting allergic and irritant contact dermatitis in 3 workers. In workers manufacturing products from polyurethane foam, attention should be paid to the risk of developing contact dermatitis. Skin problems in our study group were attributable probably to insufficient protection of the skin.

The occupational health scenario of workers engaged in the manufacturing sector in India deserves attention for their safety and increasing productivity. We reviewed the status of the manufacturing sector, identified hazards faced by workers, and assessed the existing legislations and healthcare delivery mechanisms. From October 2014 to March 2015, we did a literature review by manual search of pre-identified journals, general electronic search, electronic search of dedicated websites/databases and personal communication with experts of occupational health. An estimated 115 million workers are engaged in the manufacturing sector, though the Labour Bureau takes into account only one-tenth of them who work in factories registered with the government. Most reports do not mention the human capital employed neither their quality of life, nor occupational health services available. The incidence of accidents were documented till 2011, and industry-wise break up of data is not available. Occupational hazards reported include hypertension, stress, liver disease, diabetes, tuberculosis, eye/ hearing problems, cancers, etc. We found no studies for manufacturing industries in glass, tobacco, computer and allied products, etc. The incidence of accidents is decreasing but the proportion of fatalities is increasing. Multiple legislations exist which cover occupational health, but most of these are old and have not been amended adequately to reflect the present situation. There is a shortage of manpower and occupational health statistics for dealing with surveillance, prevention and regulation in this sector. There is an urgent need of a modern occupational health legislation and an effective machinery to enforce it, preferably through intersectoral coordination between the Employees' State Insurance Corporation, factories and state governments. Occupational health should be integrated with the general health services.

Increased mortality rates for oesophageal cancers in women (3 Obs; SMR: 5.41; 95%CI 1.74-16.8) and in men (6 Obs; SMR: 2.16; 95%CI 0.97-4.81), for malignant tumours of pancreas (16 Obs; SMR: 1.65; 95%CI 1.01- 2.70), rectum (11 Obs; SMR: 2.17; 95%CI 1.20-3.92) and kidney (11 Obs; SMR: 1.98; 95%CI 1.10-3.58) in men occupied in plastic processing. in this study, we observed an excess of mortality rates for lung cancer in men of rubber factories and for malignant tumours of the digestive tract, pancreas, and kidney in workers employed in the production of plastic articles. Nevertheless, these results must be interpreted with caution, because exposures to non-occupational risk factors, like tobacco smoke or other occupational exposures outside the companies concerned, are not known. The results suggest to continue epidemiological surveillance.

Background: Exposure-response analyses in occupational studies rely on the ability to distinguish workers with regard to exposures of interest. Aims: To evaluate different estimates of current average exposure in an exposure-response analysis on dust exposure and cross-shift decline in FEV1 among woodworkers. Methods: Personal dust samples (n = 2181) as well as data on lung function parameters were available for 1560 woodworkers from 54 furniture industries. The exposure to wood dust for each worker was calculated in eight different ways using individual measurements, group based exposure estimates, a weighted estimate of individual and group based exposure estimates, and predicted values from mixed models. Exposure-response relations on cross-shift changes in FEV1 and exposure estimates were explored. Results: A positive exposure-response relation between average dust exposure and cross-shift FEV1 was shown for non-smokers only and appeared to be most pronounced among pine workers. In general, the highest slope and standard error (SE) was revealed for grouping by a combination of task and factory size, the lowest slope and SE was revealed for estimates based on individual measurements, with the weighted estimate and the predicted values in between. Grouping by quintiles of average exposure for task and factory combinations revealed low slopes and high SE, despite a high contrast. Conclusion: For non-smokers, average dust exposure and cross-shift FEV1 were associated in an exposure dependent manner, especially among pine workers. This study confirms the consequences of using different exposure assessment strategies studying exposure-response relations. It is possible to optimise exposure assessment combining information from individual and group based exposure estimates, for instance by applying predicted values from mixed effects models.

Children at health risks.

Sekar, H R

1992-01-01

In India, 69% of the children of the working class die, most of whom are child laborers. Economic pressure forces parents to make their children work. Employers want child workers because they can manipulate them and pay them low wages, thereby ensuring their viability. The caste system induces social inequality, inheritance invokes cultural inequality, and patriarchal socialization is responsible for gender inequality, all of which perpetuates exploitation of children by employers. In Sivakasi, an estimated 125,000 children make up the child labor force, comprising 30% of the entire labor force. 75% are from the lowest castes. 90% of child workers are girls because they are more obedient and accept even lower wages than boys, and girls need to save for their dowry. Girls often suffer verbal and physical abuse. Like their parents who were also child workers, child workers are illiterate and work long hours. A small rich elite in Sivakasi controls most of the trading and industrial capital, educational institutions, and voluntary organizations. Employers' agents give parents a loan and use their children's labor as security. Each day, they bring child workers to Sivakasi in factory buses from villages to work at least 12 hour days. They work under hazardous conditions, e.g., working with toxic chemicals. Coughing, sore throat, dizziness, methemoglobinemia, and anemia are common effects of ingestion or inhalation of chlorate dust. Inhalation of sulphur dust causes respiratory infections, eye infections, and chronic lung diseases (e.g., asthma). Fires and explosions are common risks for working children. Factory management seldom undertake fire prevention measures. An extensive survey of the problem of child labor is needed in Sivakasi before systematic planning to protect children could be done. Overall development, especially agricultural development, is needed. Parents, employers, enforcement authorities, trade unions, and social groups need to be sensitized to the abomination of child labor. The government should provide monetary incentives to employers that do not use child labor and disincentives to those that do.

Nested case-control interview studies of lung cancer (610 incident cases), stomach cancer (292 incident cases), and 959 controls were conducted to follow up leads from a proportional mortality analysis of deaths among male workers in a large integrated iron-steel complex in Anshan, China. For lung cancer, after adjusting for the significant non-occupational risk factors (smoking, other pulmonary disease, family history of lung cancer, and low consumption of fruit or tea), risks were significantly elevated for those employed for 15 or more years in smelting and rolling (OR = 1.5, CI = 1.1-2.2), in the fire-resistant brick factory (OR = 2.9, CI = 1.4-5.9), in general loading (OR = 2.5, CI = 1.0-6.1), and as coke oven workers (OR = 3.4; CI = 1.4-8.5). For stomach cancer, after adjusting for consumption of pickled vegetables, prior gastric diseases, family history of stomach cancer, low intake of fruits and vegetables, and education, risks were significantly elevated for those employed for 15 or more years in ore sintering and transportation (OR = 2.1, CI = 1.0-4.4), in the fire-resistant brick factory (OR = 2.5, CI = 1.1-5.8), in general loading (OR = 3.2, CI = 1.2-8.9), as boilerworkers and cooks (OR = 2.6, CI = 1.2-5.6), and as coke oven workers (OR = 5.4, CI = 1.8-16.0). For both lung and stomach cancers, significant dose-response gradients were observed for exposure to total dust and benzo(a)pyrene, but not for specific chemical components of dust. Overall, long-term steel workers with exposure to workplace pollutants had a 40% increased risk of both lung and stomach cancers. These case-control studies confirm many of the occupational findings reported in the proportionate mortality analysis, and suggest avenues for further work to evaluate the carcinogenicity of individual components of dust.

Background Traditionally, women in Bangladesh stayed at home in their role as daughter, wife, or mother. In the 1980s, economic reforms created a job market for poor, uneducated rural women in the ready-made garment industry, mostly located in urban areas. This increased participation in paid work has changed the gender roles of these women. Women’s earnings support their family, but they are also separated from their children, with impacts on their mental health and well-being. This study explores the lived experience of women in Bangladesh working in the ready-made garment industry as they strive to be mothers and family providers, often in high-stress conditions. Methods The study was conducted in two industrial areas of Dhaka over 8 months. Data collection included a literature review, 20 in-depth interviews with married female garment workers, and 14 key-informant interviews with officials from the Ministry of Labour and Employment, health-service providers within the garment factories, factory managers, and representatives of the Bangladesh Garment Manufacturers and Exporters Association. The data collected were analyzed thematically. Results Poverty was a key motivating factor for female migrant workers to move from rural areas. Their children stay in their village with their grandparents, because of their mothers’ work conditions and the lack of childcare. The women reported stress, anxiety, restlessness, and thoughts of suicide, due to the double burden of work and separation from their children and family support. Further, they cannot easily access government hospital services due to their long work hours, and the limited medical services provided in the workplace do not meet their needs. Conclusion In order to improve the health and well-being of female garment workers, steps should be taken to develop health interventions to meet the needs of this important group of workers who are contributing significantly to the economic development of the country.

Background In 1994, a hazardous waste site, polluted by the dumping of solvents from a former electronics factory, was discovered in Taoyuan, Taiwan. This subsequently emerged as a serious case of contamination through chlorinated hydrocarbons with suspected occupational cancer. The objective of this study was to determine if there was any increased risk of breast cancer among female workers in a 23-year follow-up period. Methods A total of 63,982 female workers were retrospectively recruited from the database of the Bureau of Labor Insurance (BLI) covering the period 1973–1997; the data were then linked with data, up to 2001, from the National Cancer Registry at the Taiwanese Department of Health, from which standardized incidence ratios (SIRs) for different types of cancer were calculated as compared to the general population. Results There were a total of 286 cases of breast cancer, and after adjustment for calendar year and age, the SIR was close to 1. When stratified by the year 1974 (the year in which the regulations on solvent use were promulgated), the SIR of the cohort of workers who were first employed prior to 1974 increased to 1.38 (95% confidence interval, 1.11–1.70). No such trend was discernible for workers employed after 1974. When 10 years of employment was considered, there was a further increase in the SIR for breast cancer, to 1.62. Those workers with breast cancer who were first employed prior to 1974 were employed at a younger age and for a longer period. Previous qualitative studies of interviews with the workers, corroborated by inspection records, showed a short-term high exposure to chlorinated alkanes and alkenes, particularly trichloroethylene before 1974. There were no similar findings on other types of cancer. Conclusion Female workers with exposure to trichloroethylene and/or mixture of solvents, first employed prior to 1974, may have an excess risk of breast cancer. PMID:17559641

This study aimed to investigate whether exposure to sunflower pollen (Helianthus annuus) increases both sensitization and respiratory symptoms, and whether or not it affects lung functions in sunflower processing workers. The largest sunflower processing factories in the Thrace region of Turkey participated in this study. Workers from the units directly exposed to sunflower seed enrolled as the study group (n = 102) and workers who were not directly exposed to Helianthus annuus pollen (n = 102) were the control group. Detailed questionnaires covering respiratory and allergic symptoms were completed, and skin prick tests and lung function tests were performed. We found a very high rate (23.5%) of sensitization to Helianthus annuus in the study group compared to the controls (P<0.001). Logistic regression analysis showed that the risk of sensitization to H. annuus was increased 4.7-fold (odds ratio = 4.17, 95%) confidence interval = 1.3-16.7) if subjects were exposed to sunflower pollen in the workplace. While asthmatic symptoms and allergic skin diseases were not different between the two groups, workers in the study group had a higher rate of allergic rhinitis and conjunctivitis (P<0.05). We found that pulmonary function was significantly impaired in the study group (P<0.01). Using a multivariate analysis model, inclusion in the study group was found to be a predictive factor for impairment of lung function (P=0.002). We conclude that sunflower pollen has high allergenic potential, especially when there is close contact, and exposure to sunflower pollen in the workplace can result in impairment in lung function.

Occupational noise-induced tinnitus: does it affect workers' quality of life?

2008-02-01

This prospective study aimed to investigate the quality of life of workers in a steel factory. The study group was composed of 16 male workers with tinnitus and 30 ears. Fifteen male workers without tinnitus and 30 ears were included into the control group. Workers were evaluated by questionnaire, pure-tone audiometry, and the SF-36 Health Survey. In the study group, tinnitus loudness levels (TLLs) were found. In the study group, the domains general mental health and role limitations owing to emotional problems were significantly lower than in the control group. Older age, industrial noise exposure over a long period, higher noise exposure during work, and hearing loss secondary to occupational noise caused workers to experience higher TLLs. Earheadings protected workers more than earplugs, and TLLs were lower. Important factors that affect workers' quality of life are maximum exposed noise levels, daily and total noise exposure time, and exposure to continuous noise. Occupational noise-induced tinnitus mainly causes emotional disability rather than physical disability. Emotionally impaired QOL results may be due to tinnitus-related psychological problems. Workers should have knowledge about the hazardous effects of noise. Periodic health checkups and regular seminars have great importance. Workers must be aware of other ototoxic factors, such as medications and noisy music. In the future, researchers should develop a screening method to detect those with a more hereditary affinity to hearing loss.

Sulfur mustard (SM) and lewisite are vesicant chemical warfare agents that can cause skin blistering and chronic lung complications. During 1929-1945, a Japanese factory produced poisonous gases, which included SM, lewisite and other chemical weapons. The aim of this study was to investigate the chest computed tomography (CT) findings among long-term survivors who worked at this factory. During 2009-2012, we evaluated chest CT findings from 346 long-term survivors who worked at the poison gas factory. Skin lesions were used as an indicator of significant exposure to vesicant agents. Among the 346 individuals, 53 (15%) individuals experienced skin lesions while working at the factory, and chest CT revealed abnormal findings in 179 individuals (52%). Emphysema was the most common CT finding and was observed in 75 individuals (22%), while honeycombing was observed in 8 individuals (2%). Emphysema and honeycombing were more prevalent among individuals with skin lesions, compared to individuals without skin lesions. Multivariate analyses revealed significant associations between the presence of emphysema and skin lesions (p = 0.008). Among individuals who never smoked, individuals with skin lesions (n = 26) exhibited a significantly higher rate of emphysema, compared to individuals without skin lesions (n = 200) (35% versus 7%, respectively; p < 0.001). Among the long-term survivors who worked at the poison gas factory, a history of skin lesions was associated with the presence of emphysema, even among never smokers, which suggests that emphysema might be a long-term complication of exposure to chemical warfare agents.

Post-traumatic stress disorder (PTSD) may be more prevalent and burdensome in developing countries. The goals of this study were to (1) determine the prevalence of PTSD, (2) identify types and number of traumas related to screening positive for PTSD and (3) determine other sociodemographic risk factors and health/medical conditions that may be correlated to PTSD among garment-factory workers and a comparable working population in Bangladesh. A survey was administered to a convenient sample of 607 lower socio-economic status (SES) working women in Bangladesh, 310 of who were garment workers. The primary outcome PTSD was measured by the PTSD Checklist. The Life Events Checklist determined the number and type of traumatic events. The prevalence of PTSD was found to be 17.79% - 7.25% in garment workers and 21.55% in the comparison worker group. In multivariate analysis, PTSD was found to be significantly associated with age, income, chronic pain and number of stressful events. Participants between 45-50 years of age had the greatest odds of reporting PTSD - 15.68 fold (95% confidence interval (CI) = 4.08, 60.29) compared with those younger than 24 years. PTSD was more common in those with lower income (2,000-4,000 taka) (odds ratio (OR) = 1.60; 95% CI = 0.79, 3.26), who had chronic pain (OR = 2.48; 95% CI = 1.51, 4.07) and who experienced over three traumatic life events (OR = 11.25; 95% CI = 4.59, 27.59). The mean number of traumatic events experienced by this entire population was 4.9 with PTSD being more likely in those who experienced physical assault (OR = 6.35; 95% CI = 4.07, 9.90), who caused serious harm or death to someone else (OR = 4.80; 95% CI = 1.36, 16.87) and who had exposure to combat or war (OR = 4.76; 95% CI = 1.17, 19.34). Undiagnosed and untreated PTSD impacts the quality of life and decrease worker productivity among working-age women in this developing country.

The aim of the study was to evaluate health effects of occupational exposure to diisocyanates (DIC) among polyurethane foam products factory workers. Thirty workers had a physical examination, skin prick tests with common allergens, allergen-specific immunoglobulin E (IgE) antibodies to diisocyanates and pulmonary function tests. Concentrations of selected isocyanates in the workplace air samples as well as concentration of their metabolites in the urine samples collected from the workers of the plant were determined. The most frequent work-related symptoms reported by the examined subjects were rhinitis and skin symptoms. Sensitization to at least 1 common allergen was noted in 26.7% of the subjects. Spirometry changes of bronchial obstruction of a mild degree was observed in 5 workers. The specific IgE antibodies to toluene diisocyanate (TDI) and 4,4'-methylenebis(phenyl isocyanate) (MDI) were not detected in any of the patients' serum. Cellular profiles of the collected induced sputum (ISP) did not reveal any abnormalities. Air concentrations of TDI isomers ranged 0.2-58.9 μg/m3 and in 7 cases they exceeded the Combined Exposure Index (CEI) value for those compounds. Concentrations of TDI metabolites in post-shift urine samples were significantly higher than in the case of pre-shift urine samples and in 6 cases they exceeded the British Biological Monitoring Guidance Value (BMGV - 1 μmol amine/mol creatinine). We didn't find a correlation between urinary concentrations of TDI, concentrations in the air and concentrations of toluenediamine (TDA) in the post shift urine samples. Lack of such a correlation may be an effect of the respiratory protective equipment use. Determination of specific IgE in serum is not sensitive enough to serve as a biomarker. Estimation of concentrations of diisocyanate metabolites in urine samples and the presence of work-related allergic symptoms seem to be an adequate method for occupational exposure monitoring of DIC, which may help to determine workers at risk as well as to recognize hazardous workplaces.

Dust exposure and pneumoconiosis were investigated in a South African pottery that manufactured wall tiles and bathroom fittings. This paper describes the objectives of the investigation and presents dust measurement data. x Ray diffraction showed that the clays used by the pottery had a high quartz content (range 58%-23%, mean 38%). Exposure to respirable dust was measured for 43 workers and was highest (6.6 mg/m3) in a bathroom fitting fettler. Quartz concentrations in excess of 0.1 mg/m3 were found in all sections of the manufacturing process from slip production to biscuit firing and sorting. The proportion of quartz in the respirable dust of these sections was 24% to 33%. This is higher than is usually reported in English potteries. Four hundred and six (80%) of the 509 workers employed at the pottery were potentially at risk of occupational lung disease. The finding of large numbers of pottery workers exposed to unacceptable dust concentrations is not surprising as poor dust control was found in all six wall tile and sanitary ware factories surveyed by the National Centre for Occupational Health between 1973 and 1989. Dust related occupational disease can be expected in potters for many years to come. PMID:1637705

The aim of this study is to produce preliminary data about the validation of the "Naples-Questionnaire of Distress at Work" (nQ.DW). This inventory is a new assessment tool in order to evaluate the distress perceived in the working environment by means of the differentiation of the conditions linked to the mobbing from which related to organizational disfunction. The nQ-DW also measures the bio-psycho-social global effects of these two phenomena. The questionnaire has been administered to workers suffering of a psychopathological disturbance related to work distress and to a control group matched for the sociodemographic and working variables. The statistical analysis demonstrated a significant validity and reliability. The degree of internal coherence was satisfactory. The ROC curves allow the determination of a threshold value which allows to separate the workers subjected to mobbing and/or organizational stress from control-workers with an optimal reliability degree. The values of the area under the ROC curves show that the inventory has a high discriminating capacity. Future studies, based on a greater sample size, will be oriented to the analysis of the questionnaire by means of multivariate techniques like the factorial analysis.

Heat exposure can be a health hazard for many Australian workers in both outdoor and indoor situations. With many heat-related incidents left unreported, it is often difficult to determine the underlying causal factors. This study aims to provide insights into perceptions of potentially unsafe or uncomfortably hot working conditions that can affect occupational health and safety using information provided by the public and workers to the safety regulator in South Australia (SafeWork SA). Details of complaints regarding heat exposure to the regulator's "Help Centre" were assembled in a dataset and the textual data analysed thematically. The findings showed that the majority of calls relate to indoor work environments such as kitchens, factories, and warehouses. The main themes identified were work environment, health effects, and organisational issues. Impacts of hot working conditions ranged from discomfort to serious heat-related illnesses. Poor management practices and inflexibility of supervisors featured strongly amongst callers' concerns. With temperatures predicted to increase and energy prices escalating, this timely study, using naturalistic data, highlights accounts of hot working conditions that can compromise workers' health and safety and the need for suitable measures to prevent heat stress. These could include risk assessments to assess the likelihood of heat stress in workplaces where excessively hot conditions prevail.

Malaysian made condoms sold locally as well as exported.

PubMed

1979-01-01

Malaysia, famous for its natural rubber, is also producing condoms made from local rubber. About 40,000 gross of condoms a month are being produced by a factory with about 30 female workers. 30-40% of the production is exported to Europe, Middle East, Asia, Japan, Singapore and South America. The size of the condoms conform to international standards, 49 mm and 52 mm. As there is a greater demand for the 52 mm. condoms overseas, the company produces more of this than the 49 mm. condoms. In April 1975, the Standard Institution and Industrial Research of Malaysia gave its quality control approval to a condom which can hold 5 gallons of water and with thickness varying from 0.03 mm, 0.06 mm. and 0.05-0.07 mm. A 10% tax/piece and a 5% surtax are imposed on imported condoms to protect the local industry from foreign competition. Local condoms are sold tax-free. Pink and black colored condoms appear to be popular among consumers. Although complaints are few, 1 in 10,000 users may suffer from allergic problems because of the silicone oil treatment of the condoms. Another local condom factory which uses Malaysian rubber for condom manufacture is located in Klang, approximately 24 miles from Kuala Lumpur; the factory has 25 workers producing 12,000 gross of lubricated and non-lubricated condoms for local consumption only. There is increasing evidence that condoms are increasing in popularity in Malaysia and that the average consumer is now being more selective in choosing contraceptive methods.

Background: Occupational accidents are a major point of concern in industries. The academic community should take the first step to address the long-neglected concerns of occupational safety. Objective: To assess the prevalence and pattern of occupational accidents. Materials and Methods: A record-based, cross-sectional study was done in three tile factories of Mangalore city, in Karnataka. A total of 416 workers were analyzed for the year 2004, and data regarding age, sex, job duration, type and nature of injury, body parts involved, and time of injury were collected in a prestructured proforma. Statistical Analysis: Proportions, Chi-square test, Univariate and Multivariate analysis. Results: The overall prevalence rate of accidents was found to be 18.5%. It was found that almost around 86% of the accidents had affected the limbs (upper limb 24.7%, lower limb 61%), around half (52%) of the injuries were contributed by superficial injuries, 40% of accidents were due to stepping/striking against objects and while handling. Hand tools and machinery in motion contributed to around 20% of the accidents. Accidents were more common among the younger age group and less-experienced workers. Multiple logistic regression analyses revealed that the age group of 30-39 years had an independent significant association with accidents (OR = 0.21, P = 0.04). Conclusion: Accidents in tile industries are an important occupational health problem in this area of the country. There is a need for proper safety training of the workers. PMID:20606926

Lead induced oxidative cellular damage and long-term persistence of associated adverse effects increases risk of late-onset diseases. CaNa2EDTA chelation is known to remove contaminating metals and to reduce free radical production. The objective was to investigate the impact of chelation therapy on modulation of lead induced cellular damage, restoration of altered enzyme activities and lipid homeostasis in peripheral blood of workers exposed to lead, by comparing the selected biomarkers obtained prior and after five-day CaNa2EDTA chelation intervention. The group of smelting factory workers diagnosed with lead intoxication and current lead exposure 5.8 ± 1.2 years were administered five-day CaNa2EDTA chelation. Elevated baseline activity of antioxidant enzymes Cu, Zn-SOD and CAT as well as depleted thiols and increased protein degradation products-carbonyl groups and nitrites, pointing to Pb induced oxidative damage, were restored toward normal values following the treatment. Lead showed inhibitor potency on both RBC AChE and BChE in exposed workers, and chelation re-established the activity of BChE, while RBC AChE remained unaffected. Also, genotoxic effect of lead detected in peripheral blood lymphocytes was significantly decreased after therapy, exhibiting 18.9% DNA damage reduction. Administration of chelation reversed the depressed activity of serum PON 1 and significantly decreased lipid peroxidation detected by the post-chelation reduction of MDA levels. Lactate dehydrogenase LDH1-5 isoenzymes levels showed evident but no significant trend of restoring toward normal control values following chelation. CaNa2EDTA chelation ameliorates the alterations linked with Pb mediated oxidative stress, indicating possible benefits in reducing health risks associated with increased oxidative damage in lead exposed populations.

The study aimed at measuring exhaled breath malondialdehyde (EBC-MDA) in workers exposed to dust containing silica and at its comparison with the non-exposed control group. The cross sectional, case-control study (N = 50) was performed in a tile and ceramics production factory in Yazd, Iran. EBC-MDA was quantified in exhaled breath of the participants by a lab made breath sampler. Exposure intensity was measured according to the NIOSH 0600 method in selected homogeneous exposure groups. Additionally, spirometry test was conducted to investigate a correlation between EBC-MDA and spirometric findings in the exposed workers. There was no difference in the observed exposure intensities of silica containing dust in different units. However, "coating preparation" was the unit with the highest concentration of dust. Although, the level of EBC-MDA in the cases was slightly higher than in the controls, the difference was not statistically significant (U = 252, p = 0.464). A significant and positive correlation was found between dust exposure intensity in working units and the measured EBC-MDA of workers (r = 0.467, N = 25, p = 0.027). There were also no statistically significant differences among job categories in the exposed group for the values of FEV1% (F(3, 44) = 0.656, p = 0.584), FVC% (F(3, 44) = 1.417, p = 0.172), and FEV1/FVC% (F(3, 44) = 1.929, p = 0.139). The results showed a significant correlation between respirable dust exposure intensity and the level of EBC-MDA of the exposed subjects. However, our results did not show a significant correlation between lung function decreases and EBC-MDA. This work is available in Open Access model and licensed under a CC BY-NC 3.0 PL license.

Prevention and control of tuberculosis in workplaces: how knowledgeable are the workers in Bangladesh?

The National Tuberculosis (TB) Control Programme (NTP) of Bangladesh succeeded in achieving the dual targets of 70 % case detection and 85 % treatment completion as set by the World Health Organization. However, TB prevention and control in work places remained largely an uncharted area for NTP. There is dearth of information regarding manufacturing workers' current knowledge, attitudes and practices (KAP) on pulmonary TB which is essential for designing a TB prevention and control programme in the workplaces. This study aimed to fill-in this knowledge gap. This cross-sectional survey was done in multiple workplaces like garment factories, jute mills, bidi/tobacco factories, flour mills, and steel mills using a multi-stage sampling procedure. Data on workers' KAP related to pulmonary TB were collected from 4800 workers in face-to-face interview. The workers were quite knowledgeable about symptoms of pulmonary TB (72 %) and free- of-cost sputum test (86 %) and drug treatment (88 %), but possessed superficial knowledge regarding causation (4 %) and mode of transmission (48 %). Only 11 % knew about preventive measures e.g., taking BCG vaccine and/or refraining from spitting here and there. Knowledge about treatment duration (43 %) and consequences of incomplete treatment (11 %) was poor. Thirty-one percent were afraid of the disease, 21 % would feel embarrassed (and less dignified) if they would have TB, and 50 % were afraid of isolation if neighbours would come to know about it. Workers with formal education (AOR 1.92; 95 % CI 1.61, 2.29) and exposure to community health workers (CHW) (AOR 31.60; 95 % CI 18.75, 53.35) were more likely to have TB knowledge score ≥ mean. Workers with knowledge score ≥ mean (AOR = 1.91; 95 % CI:1.44, 2.53) and exposure to CHWs either alone (AOR = 42.4; 95 % CI: 9.94, 180.5) or in combination with print media (AOR = 37.35; 95 % CI: 9.1, 180.5) were more likely to go to DOTS centre for treatment . Only around 43 % had sputum examination despite having chronic cough of ≥ 3 weeks duration. The workers had inadequate knowledge regarding its causation, transmission and prevention which may interfere with appropriate treatment-seeking for chronic cough including sputum test. NTP needs to be cognizant of these factors while designing a workplace TB prevention and control programme for Bangladesh.

Mercury vapor is highly toxic to the human body. The present study aimed to investigate the occurrence of neuropsychological dysfunction in former workers of fluorescent lamps factories that were exposed to mercury vapor (years after cessation of exposure), diagnosed with chronic mercurialism, and to investigate the effects of such exposure on the Autonomic Nervous System (ANS) using the non-invasive method of dynamic pupillometry. The exposed group and a control group matched by age and educational level were evaluated by the Beck Depression Inventory and with the computerized neuropsychological battery CANTABeclipse - subtests of working memory (Spatial Span), spatial memory (Spatial Recognition Memory), visual memory (Pattern Recognition Memory) and action planning (Stockings of Cambridge). The ANS was assessed by dynamic pupillometry, which provides information on the operation on both the sympathetic and parasympathetic functions. Depression scores were significantly higher among the former workers when compared with the control group. The exposed group also showed significantly worse performance in most of the cognitive functions assessed. In the dynamic pupillometry test, former workers showed significantly lower response than the control group in the sympathetic response parameter (time of 75% of pupillary recovery at 10cd/m 2 luminance). Our study found indications that are suggestive of cognitive deficits and losses in sympathetic autonomic activity among patients occupationally exposed to mercury vapor.

Energy dispersive X-ray fluorescence technique was employed to determine the concentrations of elements in aerosol samples collected in the working environment of a secondary lead smelting company in Nigeria. Sampling was done using Whatman-41 cellulose filters mounted in Negretti air samplers at 10 locations within the factory. The concentrations of eight elements (K, Ca, Ti, Mn, Fe, Cu, Zn and Pb) were determined. The TSP values ranged from 70 to 7963 μg/m 3 and the concentration of Pb was found to be between 2.98 and 538.47 μg/m 3. The high Pb concentration is a danger signal to the health of the factory workers.

The workplace has been deemed a suitable location for educating many women at once about cancer screening. To determine how group education about early diagnostic methods for breast and cervical cancer effects women's behavior and readiness to receive mammography and Pap smear. This semi-interventional study was conducted at a textile factory in Istanbul, Turkey. Female workers (n= 125) were included in the study. A participant identification form and knowledge evaluation form developed for this study, along with the transtheoretical model, were used to collect data. A 45-min interactive group education was given to the participants. Upon contacting participants 3 months after group education, 15.4% (n = 11) stated that they had since received a mammogram and 9.8% (n = 7) a Pap smear. As suggested by the transtheoretical model, group education increased participants' readiness to receive cancer screening, along with their knowledge of breast and cervical cancer. Group education positively impacted women's knowledge of cancer and their readiness to receive mammography and Pap smear. Group education can potentially create awareness of cancer screening tests among women and improve their readiness to receive such tests.

Acrylates are widely used low-molecular-weight substances, initially introduced in industry in the 1930s and subsequently applied also in medicine and the home. One of their main features is the ability to undergo polymerization. The most commonly used acrylic compounds are cyanoacrylates, methacrylates, and acrylates. To confirm suspicion of occupational disease in a group of workers in an elevator factory. We studied 8 patients with dermatitis of the hands and finger pads. In their work, the patients came into contact with acrylates. Patch testing was applied with an acrylate panel (BIAL-Aristegui, Bilbao, Spain). Seven of the patients (87. 5%) had a positive result with 1% ethylene glycol dimethacrylate. Positive were also observed for 2% hydroxyethyl methacrylate (5 patients, 62. 5%), 1% triethylene glycol dimethacrylate (4 patients, 50%), 10% ethyl methacrylate monomer (3 patients, 37. 5%), 10% methyl methacrylate monomer (2 patients, 25%), 1% ethyl acrylate (1 patient, 12. 5%), and 0. 1% acrylic acid (1 patient, 12. 5%). We highlight the strong sensitizing capacity of acrylates and the importance of taking all necessary preventive measures in industries where these substances are used. Such measures should include avoidance of contact with the product in cases where sensitization has been confirmed.

The aim of this study was to determine if certain occupations or socioeconomic levels are associated with pelvic organ prolapse. Investigators at six American sites performed pelvic organ prolapse quantification examinations on women presenting for routine gynecologic care. Between September 1999 and March 2002, 1,004 patients were examined. Severe pelvic organ prolapse was defined as the leading edge being 1 cm or more beyond the hymeneal ring. The data was analyzed with the Kruskal-Wallis analysis of variance, Bonferroni test, multiple logistic regression, and descriptive statistics. The prevalence of severe pelvic organ prolapse in our group was 4.3%. Women who were laborers/factory workers had significantly more severe prolapse than the other job categories (p < 0.001). Women with annual income of Dollars 10,000 or less had significantly more severe pelvic organ prolapse than other income groups (p < 0.001). These differences persisted even when controlling for age, race, number of deliveries, body mass index >30, and smoking status (all p < 0.001). Laborers/factory worker jobs and an annual household income of Dollars 10,000 or less are associated with severe pelvic organ prolapse.

Introduction: Hearing impairment remains the main occupational health problem in the manufacturing industry, and its contributing factors have not been well controlled. Methods: Unmatched case control and comparative studies were carried out among fertilizer factory workers in Sarawak with the aim of determining contributing factors for hearing impairment. Respondents consisted of 49 cases that were diagnosed from 2005 to 2008 with 98 controls from the same work places. Chi-square test and Mann-Whitney test were used in a univariate analysis to determine the association between hearing impairment and the contributing risks being studied. Results: The results of the univariate analysis showed that hearing impairment was significantly (p<0.05) associated with older age, lower education level, high smoking dose, high occupational daily noise dose, longer duration of service, infrequent used of hearing protection device (HPD), and low perception of sound on HPD usage. Multivariate logistic regression of hearing impairment after controlling for age found the following five variables: occupational daily noise dose ≥50% (OR 3.48, 95% CI 1.36-8.89), ≥15 years of services (OR 2.92, 95% CI 1.16-7.33), infrequent use of HPD (OR 2.79, 95% CI 1.15-6.77), low perception of sound on HPD (POR 2.77, 95% CI 1.09-6.97), and smoking more than 20 packs per year (OR 4.71, 95% CI 1.13-19.68). Discussion: In conclusion, high occupational noise exposure level, longer duration of service, low perception of sound on HPD, infrequent used of HPD, and smoking more than 20 packs per year were the contributing factors to hearing impairment, and appropriate intervention measures should be proposed and taken into considerations.

(1) To investigate the response to a serum antigen-detecting ELISA for cysticercosis and a stool coproantigen test for taeniasis in two rural communities (mountainous and coastal areas) and one group of (peri-)urban factory workers; and (2) to examine clinical features of human cysticercosis in northern Vietnam. Villagers and factory workers and their families were informed and invited to participate in the study. Blood and faecal samples were collected from the participants and a simple questionnaire on taeniasis/cysticercosis completed. Serum was examined for the presence of circulating cysticercus antigen by a monoclonal-based sandwich ELISA. Ag-ELISA positive persons underwent a clinical examination and a computed tomography (CT) scan. Stool samples were examined microscopically for the presence of Taenia eggs and for copro-antigens. Tapeworms were identified following therapeutic expulsion using morphology and PCR-RFLP. Circulating cysticercus antigens, suggesting active infection, were detected in 5.3% (16/303), 0.6% (1/175) and 0.0% (0/229) of the sampled individuals from the mountainous, coastal and urban regions, respectively. Clinical examination and CT scan of the cysticercus antigen positive persons showed that active cysticercosis did not cause severe disease in most cases. Taenia copro-antigens were found in 0.3% (1/297), 1.8% (3/166) and 0.0% (0/228) of the stool samples from the mountainous, coastal and urban communities, respectively. Three tapeworms were expelled after treatment: two Taenia solium and one Taenia saginata. This survey points to a focal distribution of taeniasis/cysticercosis and suggests that human cysticercosis is rather acquired due to close contact with a T. solium carrier and self-infection, than through infection from the environment.

The ontology of the questionnaire: Max Weber on measurement and mass investigation.

PubMed

Brain, R M

2001-12-01

Although contemporary sociologists of science have sometimes claimed Max Weber as a methodological precursor, they have not examined Weber's own writings about science. Between 1908 and 1912 Weber published a series of critical studies of the extension of scientific authority into public life. The most notable of these concerned attempts to implement the experimental psychology or psycho-physics laboratory in factories and other real-world settings. Weber's critique centered on the problem of social measurement. He emphasized the discontinuities between the space of the laboratory and that of the factory, showing how several qualitative and historically conditioned differences between the two settings rendered the transfer of instruments and methods between them highly problematic. Weber's critical arguments prepared the ground for his greatest foray into empirical sociology, a survey he directed for the Verein für Sozialpolitik investigating the conditions and attitudes affecting the lives and performance of industrial workers. Using a different measuring instrument - the questionnaire - Weber tried to implement a concept of social measurement which implied a different ontology, drawn not from natural sciences but from the historical sciences.

Heat stress in glass industry is mainly studied in large and highly mechanized manufacturing Units. To the contrary, few studies were carried out in small factories specialized in hand-made products. To stress the need of combined objective and medical surveys in these environments, this paper deals with a simultaneous climatic and physiological investigation of working conditions in artistic crystal glass factories in Tuscany (Italy). The microclimatic monitoring, through a continuous survey has been carried out in early spring. The main physiological parameters (metabolic rate, heart rate, tympanic temperature and water loss) were measured over the whole shifts. The results show that, despite the arduousness of the working conditions, the heat stress levels are physiologically tolerable. The predictions made using the PHS model at the Analysis level described in ISO 15265 agree closely to the observed values, validating the use of PHS model in these conditions. This model was then used to analyse what is likely to be the situation during the summer. It is concluded that the heat constraint will be very high and that some steps must be taken from the spring to monitor closely the exposed workers in the summer and take measures to prevent any heat accident.

In the present work the chemical compositions of the products used in shoes manufacturing are reported. The data were collected over the period 2004-2007 in 156 shoe factories in Vigevano area during a study aiming the evaluation of safety conditions and occupational exposure to hazardous chemicals of the employees. The study was part of a regional project for "Occupational cancer prevention in the footwear industry". In the first phase of the study an information form on production cycle, products used and their composition was filled during preliminary audit. In the second phase of the study an in depth qualitative/quantitative evaluation of professional exposure was conducted in 13 selected shoe factories. Data analysis showed the increase in use of water-based adhesives at expense of solvent-based adhesives, the reduction to less than 3.5 weight %, and up to 1 weight %, of n-hexane concentration in solvent mixtures, the increase in use of products containing less hazardous ketones, esters, cyclohexane and heptane. Only in very few cases, products containing from 4 to 12 weight% of toluene were used. These data attest a positive trend in workers risks prevention in shoes industry.

To measure the prevalence of dry eye syndrome (DES) among clean room (relative humidity ≤1%) workers from 2011 to 2013. Three annual DES examinations were performed completely in 352 clean room workers aged 20-40 years who were working at a secondary battery factory. Each examination comprised the tear-film break-up test (TFBUT), Schirmer's test I, slit-lamp microscopic examination, and McMonnies questionnaire. DES grades were measured using the Delphi approach. The annual examination results were analyzed using a general linear model and post-hoc analysis with repeated-ANOVA (Tukey). Multiple logistic regression was performed using the examination results from 2013 (dependent variable) to analyze the effect of years spent working in the clean room (independent variable). The prevalence of DES among these workers was 14.8% in 2011, 27.1% in 2012, and 32.8% in 2013. The TFBUT and McMonnies questionnaire showed that DES grades worsened over time. Multiple logistic regression analysis indicated that the odds ratio for having dry eyes was 1.130 (95% CI 1.012-1.262) according to the findings of the McMonnies questionnaire. This 3-year trend suggests that the increased prevalence of DES was associated with longer working hours. To decrease the prevalence of DES, employees should be assigned reasonable working hours with shift assignments that include appropriate break times. Workers should also wear protective eyewear, subdivide their working process to minimize exposure, and utilize preservative-free eye drops.

We assessed the exposure levels of noise, estimated prevalence, and identify risk factors of noise-induced hearing loss (NIHL) among male workers with a cross-sectional study in a liquefied petroleum gas cylinder infusion factory in Taipei City. Male in-field workers exposed to noise and administrative controls were enrolled in 2006 and 2007. Face-to-face interviews were applied for demographics, employment history, and drinking/smoking habit. We then performed the measurements on noise levels in field and administration area, and hearing thresholds on study subjects with standard apparatus and protocols. Existence of hearing loss > 25 dBHL for the average of 500 Hz, 1 kHz, and 2 kHz was accordingly determined for NIHL. The effects from noise exposure, predisposing characteristics, employment-related factors, and personal habits to NIHL were estimated by univariate and multivariate logistic regressions. A total of 75 subjects were involved in research and 56.8% of in-field workers had NIHL. Between the in-field and administration groups, hearing thresholds on the worse ear showed significant differences at frequencies of 4 k, 6 k, and 8 kHz with aging considered. Adjusted odds ratio for field noise exposure (OR=99.57, 95% CI: 3.53, 2,808.74) and frequent tea or coffee consumption (OR=0.03, 95% CI: 0.01, 0.51) were found significant. Current study addressed NIHL in a specific industry in Taiwan. Further efforts in minimizing its impact are still in need.

The genotoxic effects of air pollutant exposures have been studied in people living and working in Map Ta Phut, Rayong province, Thailand, a site where is located the Map Ta Phut Industrial Estate (MIE) one of the largest steel, refinery and petrochemical complex in the South-Eastern Asia. This was done by the conduction of a transversal study aimed to compare the prevalence of bulky DNA adducts in groups of subjects experiencing various degree of air pollution. DNA adduct analysis was performed in the leukocytes of 201 volunteers by the (32)P-postlabelling assay: 79 were workers in the MIE complex, including 24 refinery workers, 40 steel workers and 15 tinplate workers, 72 were people residing downwind in the MIE area and 50 were residents in a control district of the same Rayong province but without industrial exposures. The groups of workers were analyzed separately to evaluate if DNA adduct formation differs by the type of industry. The levels of bulky DNA adducts were 1.17+/-0.17 (SE) adducts/10(8) nucleotides in refinery workers, 1.19+/-0.19 (SE) in steel workers, 0.87+/-0.17 (SE) in tinplate workers, 0.85+/-0.07 (SE) in MIE residents and 0.53+/-0.05 (SE) in district controls. No effects of smoking habits on DNA adducts was found. The multivariate regression analysis shows that the levels of DNA adducts were significantly increased among the individuals living near the MIE industrial complex in respect to those resident in a control district (p<0.05). In the groups of occupationally exposed workers, the highest levels of DNA adducts were found among the workers experiencing an occupational exposure to polycyclic aromatic hydrocarbons, e.g. the steel factory and refinery workers. When we have evaluated if the levels of DNA adducts of the PAH exposed workers were different from those of the MIE residents, a statistical significantly difference was found (p<0.05). Our present study indicates that people living near point sources of industrial air pollution can experiment an excess of DNA adduct formation. The emissions from the MIE complex are the main source of air pollution in this area and can be the cause of such increment in the levels of DNA damage.

To assess the length and quality of sleep among shift workers at Bahir Dar textile mill. A cross sectional study using structured questionnaire that contained sociodemographic variables, duration of work, work schedule, number of sleeping hours, sleep disorders, and associated reasons for such disorders. A textile mill in Bahir Dar, northwest Ethiopia. Three-hundred ninety four random sample of production workers of the mill. Sleep disorders, and the impact of external and home environment on sleep. The mean duration of work in the factory was 25.4 +/- 7.1 years. Ninety-seven per cent of the study population work in a rotating eight hourly shift system. The mean number of hours a worker sleeps after a worked shift was 5.1 +/- 2.3. Two hundred thirty (58.4%) claimed to experience a sleep disorder. Sleep disturbance was significantly associated with rotating shift work, external environmental noise, and working in the spinning department. The majority of the workers in Bahir Dar textile mill experienced sleep disturbances as detailed in the study methodology.

2005-02-01

A participatory ergonomics programme was implemented in an automotive parts manufacturing factory. An ergonomics change team was formed composed of members from management and the organized labour union. It was hypothesized that the physical change projects implemented as part of this process would result in decreased worker exposures to peak and cumulative physical demands and reduced worker perceptions of physical effort and pain severity. A quasi-experimental design was employed, utilizing a sister plant in the corporation as a referent group. A longitudinal questionnaire approach was used to document pre-post changes in worker perceptions. In general, the physical change projects were rated as improvements by workers and were successful at reducing peak and/or cumulative mechanical exposures. However, there were few systematic changes in perceived effort or pain severity levels. Explanations include the confounding effects of differential production rate and staffing changes at the intervention and referent plants and/or insufficient overall intervention intensity due to a relatively short intervention period, plant and team ambivalence towards the process and the low overall impact on exposure of the particular changes implemented.

The aim of this study was to investigate whether exposure to hexavalent chromium induces lipid peroxidation in human. This study involved 25 chrome-plating factory workers and a reference group of 28 control subjects. The whole-blood and urinary chromium concentrations were determined by graphite furnace atomic absorption spectrophotometry. Malondialdehyde (MDA), the product of lipid peroxidation, was determined by high-performance liquid chromatography, and the activities of protective enzymes were measured by ultraviolet-visible spectrophotometry. In the chrome-plating workers, the mean concentrations of chromium in blood and urine were 5.98 microg/L and 5.25 microg/g creatinine, respectively; the mean concentrations of MDA in blood and urine were 1.7 micromol/L and 2.24 micromol/g creatinine. The concentrations of both chromium and MDA in blood and urine were significantly higher in the chromium-exposed workers. The activities of superoxide dismutase (SOD), glutathione peroxidase (GPX), and catalase (CAT) were not markedly different between control and exposed workers. Data suggest that MDA may be used as a biomarker for occupational chromium exposure. Antioxidant enzymic activities are not a suitable marker for chromium exposure.

The food and agriculture industry employs 15% of the female industrial work force in France. Workers in this industry are exposed to a variety of environmental and organizational constraints: cold, uncomfortable postures, assembly-line work, irregular schedules. In 1987 to 1988, a medical examination and questionnaire were administered to 726 menstruating women who had not been pregnant during the 2 previous years, as part of a study of French workers in 17 poultry slaughterhouses and 6 canning factories. Dysmenorrhea during the previous year was more prevalent among younger women and smokers, and less prevalent among users of oral contraceptives. After adjustment for nonoccupational variables, dysmenorrhea was significantly related to several parameters expressing cold exposure and physical work load. Other parameters such as job satisfaction and hours of domestic work were not associated with dysmenorrhea.

5 production operators from 2 factories manufacturing thermosetting coating paint developed work-related skin disorders within 12 months of the introduction of a new powdered paint product. All 5 workers were found to have allergic contact dermatitis from 2 epoxy resin hardeners, both of which were commercial preparations of triglycidyl isocyanurate (TGIC). 2 of the workers had concomitant sensitization to epoxy resin in the standard series and several of the epoxy resin preparations at the workplace. TGIC has been reported as a contact sensitizer both in persons producing the chemical and among end-users of TGIC-containing products. These 5 reported cases document allergic contact dermatitis from commercial TGIC among exposed workers during an intermediate process of powdered paint manufacture. The possibility of substituting this epoxy resin hardener with less sensitizing alternatives should be explored.

A deadly factory fire in Karachi, Pakistan caused the death of 289 workers on September 11, 2012. The havoc played by fire could have been avoided if the concerned authorities had better fire safety measures and strategy. This article presents an exploratory study designed to obtain first-hand information about this issue in which data were collected from 135 organizations within various industries of Pakistan. The results of this study are alarming because most of the organizations are not even equipped with basic fire safety equipment and are devoid of fire exit paths. Incompetence and negligence on the part of government agencies and many stakeholders frequently allows fire to play havoc with the lives of workers in Pakistani organizations, confirming the famous saying 'Parva saepe scintilla contempta magnum excitavit incendium' (A spark neglected has often raised a conflagration).

The occupation of the people can influence the development of metabolic syndrome. To determine the association between metabolic syndrome and its determinants with the job rank in workers of a large car factory in Iran. 3989 male workers at a large car manufacturing company were invited to participate in this cross-sectional study. Demographic and anthropometric data of the participants, including age, height, weight, and abdominal circumference were measured. Blood samples were taken to measure lipid profile and blood glucose level. Metabolic syndrome was diagnosed in each participant based on ATPIII 2001 criteria. The workers were categorized based on their job rank into 3 groups of (1) office workers, (2) workers with physical exertion, and (3) workers with chemical exposure. The study characteristics, particularly the frequency of metabolic syndrome and its determinants were compared among the study groups. The prevalence of metabolic syndrome in our study was 7.7% (95% CI 6.9 to 8.5). HDL levels were significantly lower in those who had chemical exposure (p=0.045). Diastolic blood pressure was significantly higher in those who had mechanical exertion (p=0.026). The frequency of metabolic syndrome in the office workers, workers with physical exertion, and workers with chemical exposure was 7.3%, 7.9%, and 7.8%, respectively (p=0.836). Seemingly, there is no association between metabolic syndrome and job rank.

In 24 April 2013, Rana Plaza - a high-rise building in Bangladesh where garments were being made for the Western markets collapsed. In this study, we report on the surviving workers' physical strength, self-efficacy, and disability level one year after the disaster. This cross-sectional study took place at the Centre for the Rehabilitation of the Paralysed (CRP) which provided care for more than 600 victims. For this study, upper extremity strength among the survivors was assessed by dynamometer hand grip (HG) and lower extremity strength by five time sit to stand test (FTSST). The WHODAS tool measured level of disability and General Self-Efficacy questionnaire measured self-efficacy. Post-traumatic stress disorder (PTSD) prevalence was determined by the PCL-scale. The study recruited 181 injured workers. The mean disability score among them was 49.8 (SD 17.5) and mean self-efficacy score was 24.9 (SD 6.9). In multivariate models, after adjusting for age, gender, education, injury profile, employment, marital status and job category, self-efficacy was found to be higher among those who scored above median HG test score [β= -2.32 (95% CI: -4.63, -0.01)] and FTSST performance score [β= -2.69 (95% CI: -4.93, -0.46)]. The disability level was found to be significantly associated with PTSD score [β = 0.84 (95% CI: 0.62, 1.06)] and self-efficacy score [β= -0.45 (95% CI: -0.78, -0.13)]. There is an immense need to develop and deliver effective post-injury recovery, rehabilitation and return-to-work programs for injured workers in resource poor countries. Implications for Rehabilitation The study findings suggest that one year after the factory disaster in Bangladesh, the injured workers are suffering from a high degree of disability, low physical performance and reporting low self-efficacy. The national and international stakeholders including Western buyers, aid agencies, NGOs, worker advocacy groups, consumer associations and the government of Bangladesh can be updated on the progress made so far. There is an immense need to develop and deliver effective post-injury recovery, rehabilitation and return-to-work programs for injured workers in resource poor countries. International organizations like ILO, WHO, World Bank can help developing countries in building these capacities.

2013-08-01

A study was conducted to measure the effects of attitudes and beliefs on the risk judgments of health care workers. Lack of hand hygiene compliance is a worldwide issue in health care, contributing to infections, fatalities, and increased health care costs. Human factors methods are a promising solution to the problem of compliance, although thus far, the concentration has been on process and engineering methods, such as the design of no-touch sinks. Factors internal to the health care worker, such as their attitudes and beliefs about hand hygiene, have received less attention. For this study, three groups of health care workers completed measures of attitudes, control beliefs, and hand hygiene knowledge. They then provided risk judgments of touching various surfaces via a factorial survey. Attitudes, knowledge, control beliefs, and surface type all predicted the risk judgments of the sample of health care workers, with differences between professional groups. Health care workers perceive less risk when touching surfaces,which may explain historically low rates of hand hygiene compliance after surface contact. Although more research is needed to directly connect risk judgments to failures of hand hygiene, the current results can inform interventions targeting the internal attitudes and beliefs of health care workers.

Occupational dermatoses were investigated in a factory producing rotor blades for wind turbines by an epoxy-based process. In a blinded study design, 603 workers were first interviewed and thereafter clinically examined. Based on a history of work-related skin disease, clinical findings of dermatitis, or both, 325 (53.9%) of the workers were patch tested with a specially profiled occupational patch-test series and the European standard patch-test series. Calculated on all investigated workers, 17.1% of the workers were diagnosed with occupational dermatoses caused by work. Occupational allergic contact dermatitis was found in 10.9% of the workers. The estimated frequency of irritant contact dermatitis caused by work was 6.1%. Dermatitis on the hands was associated with contact allergy to epoxy resin (P = 0.017). The number of days on leave before the clinical examination was negatively associated with the presence of dermatitis (P = 0.001). Among workers employed 7-12 months, the frequency of occupational contact allergy was higher than that among workers employed for

To determine whether occupational exposure of men to hydrocarbons has adverse effects on the quality of their semen. Comparative study. The rubber industry in Mexico City. Forty-eight workers who were exposed to hydrocarbons for 2-24 years and 42 unexposed workers. None. Environmental hydrocarbon concentrations were determined by continuous air monitoring in all areas of the factory. Analyses of semen samples were performed in accordance with World Health Organization criteria. Hydrocarbon concentrations were as follows: ethylbenzene, 220.7-234 mg/m3; benzene, 31.9-47.8 mg/m3; toluene, 189.7-212.5 mg/m3; and xylene, 47-56.4 mg/m3. The number of subjects with ejaculates that had normal characteristics was greater in the unexposed group (76%) than in the exposed group (17%). More abnormal characteristics were found in the semen of exposed workers than unexposed workers, including alterations in viscosity, liquefaction capacity, sperm count, sperm motility, and the proportion of sperm with normal morphology. Some abnormal characteristics correlated with the number of years of exposure to the hydrocarbons. Damage to the spermatogenic process resulting from hydrocarbon exposure was demonstrated by an increased rate of abnormalities in the semen of exposed workers compared with unexposed workers. This information may be useful for conducting future analyses of reproductive risks related to exposure to high concentrations of hydrocarbons.

Shoes factory workers are engaged in ripetitive tasks, often performed in constrained postures and in concomitance of force applied, which result in increased risk of musculoskeletal disorders. Risk assessment and ergonomic interventions are part of the on-site prevention program, which should pertain also to gender and age differences.

Participatory Action-Oriented Training (PAOT) has been known as a practical training methodology for improving health and safety at work, particularly for small- and medium-sized enterprises (SMEs). Our hypothesis is that PAOT is a better approach than a traditional local method, and the objective of this study was to evaluate the efficacy of PAOT and to make suggestions for improvement. An intervention was performed for one year at 20 volunteer SMEs. PAOT was applied in 10 factories, and a traditional local method was applied in the other 10 SMEs as a control. Two cross-sectional studies were performed consisting of a questionnaire and environmental measurements. Data were also collected on the number of factory improvements, productivity, worker income, accidents, and health costs. There were significant improvements among the intervention factories in terms of work environment, number of improvements and health costs between the pre- and post- intervention phases. In terms of productivity, significant increases were seen in the civil engineering, metal, garment, and rice mill industries in the intervention group, while the metal casting and, garment industries in the control group also showed significant increase in productivity. The findings support the idea that a PAOT program produces better outcomes in SMEs. It is recommended that a PAOT program be widely applied to SMEs to improve health and safety. A fuller examination could be obtained with more environmental measurements taken over a much longer period of time, together with data on sickness absence and accidents that have been independently validated.

Workers in the granite industry face an occupational hazard: silicosis due to the crystalline silica present in inhalable dust. As granite can also present a variable, and occasionally significant, content of naturally occurring radionuclides, they may also face a radiological hazard. In order to assess the risk, a granite industry with a quarry and processing factory was selected to assess the occupational exposure. Three main potential pathways were observed: external irradiation, inhalation of granite dust, and radon exposure. The external dose rate was similar to that in a nearby farming area. A slight increment (0.016-0.076 mSv yr -1 ) was observed in the quarry and stockpile, due to quarry faces and granite blocks. The effective dose due to granite dust inhalation was 0.182  ±  0.009 mSv yr -1 in the worst case scenario (3 mg m -3 dust load in air and no use of filter masks). Thus, the mean value of the effective dose from these two pathways was 0.26 mSv yr -1 , lower than the reference level of 1 mSv yr -1 for the general population. The annual mean value of radon concentration in the indoor air was 33 Bq m -3 . However, during granite processing works the radon concentration can increase up to 216 Bq m -3 , due to mechanical operations (sawing, polishing, sanding, etc). This radon concentration was below the 600 Bq m -3 reference level for action in working places. Therefore, workers in this granite factory face no significant additional radiological exposure, and no-one needs to be designated as occupationally exposed and subject to individual dosimetry.

Acute increase in tuberculosis mortality between 1885 and 1910 could be explained by rapidly increased birth rate, consequently large expansion of noninfected population, and gradual increase in opportunity of contact with infectious patients by changing working environments and living conditions. Prevalence of tuberculosis patients was not so few in the beginning of Meiji era. Vicious spiral of increased young susceptibles, many infectious sources and increased opportunity of infection had been continued for long. Lower nutrition from infant to adult, hard work and poor living conditions had worsen prognosis of the patients. Nation-wide tuberculosis control campaign, mainly avoiding contact with patients and contaminated materials had started around 1910 and then issued Factory act which had been improved working conditions in the factories, although the speed was very slow. Tuberculosis mortality began to decrease in 1910s, but sharp temporary rise of tuberculosis mortality was marked in 1918-19 by epidemic of influenza, then the mortality had been declined again. Excess mortality by influenza caused temporary reduction of infectious sources, which had affected mortality rate of tuberculosis in the younger ages after 1920. Large raise-up of wages for factory workers around 1920 and increase trend in income for other workers by economic growth since 1900 had been improved not only working and living conditions, but also dietary life with increased higher intake of animal foods. Female excess deaths from tuberculosis comparing those of males had continued until 1930, then male mortality exceeded females. Mobilization of young women to spinning and textile industries in Meiji and Taisho eras forced to increase in tuberculosis mortality among them.(ABSTRACT TRUNCATED AT 250 WORDS)

Stable circadian rhythm is important for both maternal and fetal health. This retrospective analysis of women in a semiconductor factory evaluated the effect of shift work exposure on childbearing and birth weight. Records of 440 female employees (initial mean age: 28.4 years) including 111 mothers who had 158 live births during the period of observation (1997-2007) were reviewed. The data analyzed included maternal age, general health condition, highest educational level, life-style and occupational factors, as well as newborn gender, birth weight, birth order and gestational age. The childbearing rates of female workers on three different work schedules (consistent daytime work (CDW), intermittent (i-) or persistent (p-) rotating shift works (RSW)) were 32.1%, 20.0% and 25.4%, respectively (P=0.047). After controlling for potential confounding factors, childbearing rates among women with CDW exceeded those of shift workers (odds ratio (OR), 1.7; 95% confidence interval (CI), 1.0-3.0). The birth weights of newborns from mothers on the three work schedules (CDW, i-RSW and p-RSW) were significantly different (3271.7±395.4, 3251.3±460.9, and 2998.5±381.2 g, respectively (P<0.01). Newborns within the lightest birth weight quintile were significantly more likely to be born to mothers with exposure to p-RSW (OR, 4.3; 95% CI, 1.1-16.8). Rotating shift work exposure was significantly associated with decreased childbearing and lighter birth weight in women working in this semiconductor manufacturing factory. Work schedules should be carefully planned for female employees who are pregnant or preparing for pregnancy. Prenatal evaluations for mothers with persistent day-night rotating shift work exposures are especially necessary.

This paper investigates the relation between wood dust exposure in the furniture industry and occupational hygiene variables. During the winter 1997-98 54 factories were visited and 2362 personal, passive inhalable dust samples were obtained; the geometric mean was 0.95 mg/m(3) and the geometric standard deviation was 2.08. In a first measuring round 1685 dust concentrations were obtained. For some of the workers repeated measurements were carried out 1 (351) and 2 weeks (326) after the first measurement. Hygiene variables like job, exhaust ventilation, cleaning procedures, etc., were documented. A multivariate analysis based on mixed effects models was used with hygiene variables being fixed effects and worker, machine, department and factory being random effects. A modified stepwise strategy of model making was adopted taking into account the hierarchically structured variables and making possible the exclusion of non-influential random as well as fixed effects. For woodworking, the following determinants of exposure increase the dust concentration: manual and automatic sanding and use of compressed air with fully automatic and semi-automatic machines and for cleaning of work pieces. Decreased dust exposure resulted from the use of compressed air with manual machines, working at fully automatic or semi-automatic machines, functioning exhaust ventilation, work on the night shift, daily cleaning of rooms, cleaning of work pieces with a brush, vacuum cleaning of machines, supplementary fresh air intake and safety representative elected within the last 2 yr. For handling and assembling, increased exposure results from work at automatic machines and presence of wood dust on the workpieces. Work on the evening shift, supplementary fresh air intake, work in a chair factory and special cleaning staff produced decreased exposure to wood dust. The implications of the results for the prevention of wood dust exposure are discussed.

The most common occupational disease that is compensated by Industrial Accident Compensation Insurance (IACI) in Korea is musculoskeletal disease (MSD). Although complaints about the workers' compensation system have been raised by injured workers with MSD, studies that examine workers' experiences with the Korean system are rare. This paper is a qualitative study designed to examine injured workers' experiences with the workers' compensation system in Korea. The aim of this study is to explore the drawbacks of the workers' compensation system and to suggest ways to improve this system. All workers from an automobile parts factory in Anseong, GyeongGi province who were compensated for MSD by IACI from January 2003 to August 2013 were invited to participate. Among these 153 workers, 142 workers completed the study. Semi-structured open-ended interviews and questionnaires were administered by occupational physicians. The responses of 131 workers were analyzed after excluding 11 workers, 7 of whom provided incomplete answers and 4 of whom were compensated by accidental injury. Based on their age, disease, department of employment, and compensation time, 16 of these 131 workers were invited to participate in an individual in-depth interview. In-depth interviews were conducted by one of 3 occupational physicians until the interview contents were saturated. Injured workers with MSD reported that the workers' compensation system was intimidating. These workers suffered more emotional distress than physical illness due to the workers' compensation system. Injured workers reported that they were treated inadequately and remained isolated for most of the recuperation period. The compensation period was terminated without ample guidance or a plan for an appropriate rehabilitation process. Interventions to alleviate the negative experiences of injured workers, including quality control of the medical care institutions and provisions for mental and psychological care for injured workers, are needed to help injured workers return to work earlier and more healthy.

In the manufacture of zinc oxide the raw material normally used in zinc metal plates. In a factory in which old aeroplane batteries containing zinc mercury amalgam were substituted, it was not realized that mercury vapour was being produced. Of 25 workers exposed, seven developed serious chronic mercury poisoning and were admitted to hospital. The clinical findings in the affected workers are described. They were first treated with penicillamine D, but in all but one case this had to be stopped because of rashes. Little improvement followed a switch to B.A.L. It is suggested that if penicillamine D is used in the treatment of mercury poisoning, steroid cover should be given from the start. PMID:14249900

OBJECTIVES: To describe the prevalence of self reported musculoskeletal complaints in the back, arms or neck, and legs among workers in the spinning industry, and to investigate the relations between these complaints and work related variables. METHODS: An interview based questionnaire survey was carried out in two spinning industry factories in Lithuania. RESULTS: The study group consisted of all workers in production (n = 363). Symptoms of the legs were the musculoskeletal symptom reported most often (61%). Many subjects had arms or neck (55%) or back problems (28%). 20% had experienced pain from all three sites. Almost 25% had had musculoskeletal pain every day and 16% had experienced constant pain during previous year. Packers had the highest risk of arms or neck problems whereas spinners had the highest risk of back or leg problems. Working in a strained posture (bending, work with arms raised up above shoulder level, and repetitive movements of the fingers) was associated with all three complaints. Only arms or neck complaints were associated with age. CONCLUSIONS: Musculoskeletal disorders are a common problem among workers producing gobelin or synthetic thread in Lithuania and working in a strained posture is a risk factor for developing musculoskeletal disorders in three body sites: legs, arms or neck, and back. To better understand the different aspects of physical load as risk factors, a more detailed study of the frequency of postural changes as well as an observation of individually adopted postures would be necessary. This applies to intervention studies in factories of the spinning industry to prevent complaints of the legs and shoulders.   PMID:10474538

Smoking and young women in Vietnam: the influence of normative gender roles.

Smoking in Vietnam, as elsewhere in Asia, is strongly sex-linked. A 1997 national prevalence survey found about half of males but just 3.4% of females used tobacco regularly. Little is known about smoking-related health awareness or attitudes in Vietnam. There is concern that women may take up smoking if rapid social change brings alteration in traditional gender norms that discourage this behaviour. Effective tobacco control depends upon accurate understanding of prevailing knowledge and views. This paper reports on a 1999-2000 collaborative study into smoking attitudes, practices and health awareness, with particular reference to gender norms. A survey, based partly on findings from initial focus groups, was administered to young female students (n = 1018) and factory workers (n = 1002) in Ho Chi Minh City, Vietnam's largest metropolis. Participants were recruited through random cluster sampling. Results indicated that smoking continues to be shunned by the vast majority of young urban students and factory workers, although prevalence was slightly higher than found in national surveys, and there was a moderate degree of experimentation. Perhaps of greater concern was the degree of ambivalence voiced about taking up smoking in the future. Moreover, while nearly all expressed awareness of negative health effects of tobacco, these were vaguely worded and excluded key mortality risks. Gender norms appeared to be strongly enduring, with female non-smoking attributed overwhelmingly to its 'inappropriateness'. Male smoking was seen as normative. Overall, workers (representing a low-income, less-educated population) had higher rates of tobacco use and less health knowledge than students. The paper concludes with a discussion about ramifications for public health interventions.

[Purpose] The purpose of this study was to investigate the effects of a Nintendo Wii exercise program on chronic work-related LBP compared with stability exercise. [Methods] Twenty-four workers participated in this study. All of the participants were diagnosed with chronic LBP by a physician. Participants were randomly assigned to three groups: a control group (CG), lumbar stabilization exercise group (LSE), and Nintendo Wii exercise group (NWE). Participants were treated 3 times a week for 8 weeks. Each session lasted 30 minutes. [Results] The results demonstrated that exercise programs improved significantly physical functions related to LBP. In health-related QOL, the Nintendo Wii exercise program significantly improved both the mental and physical health composites, but other groups had significant improvement only in the physical health composite. [Conclusion] The Nintendo Wii exercise program could be a biopsychosocial intervention for work-related LBP in factory workers.

An epidemiologic study on vaginal colonization of group B streptococcus (GBS) from non-pregnancy women was carried out. Two hundred sixty seven female workers were studied. The carrier rate of GBS in vaginal specimens was 10.86%. Women aged 45 years old and above had more cases with genital tract GBS colonization. Women with vaginal colonization had more history of miscarriage and using IUD. We did not find the positive correlations between vaginal colonization and oral contraceptive, ovarian cyst, hysteromyoma in our study group. Women with gynecologic inflammation had more cases with vaginal GBS colonization. There is a significant increase for women with vaginitis and cervicitis. Serotyping study showed that types III and II were the most frequent GBS types isolated from the carriers. Antibiotic sensitivity test showed that more than half GBS strains were resistant to oxcillin and amikacin.

Tobacco use is the second cause of death and first cause of preventable mortality worldwide. Smoking in the workplace is particularly concerning. Smoking-free workplaces decrease the risk of exposure of non-smoking personnel to cigarette smoke. Recent studies have mostly focused on the effect of daily or non-occupational stressors (in comparison with occupational stress) on prevalence of smoking. Occupational stress is often evaluated in workplaces for smoking cessation or control programs, but the role of non-occupational stressors is often disregarded in this respect. This cross-sectional study was conducted in an automobile manufacturing company. The response of automotive industry workers to parts of the validated, reliable, Farsi version of Musculoskeletal Intervention Center (MUSIC)-Norrtalje questionnaire was evaluated. A total of 3,536 factory workers participated in this study. Data were analyzed using SPSS and P<0.05 was considered statistically significant. The correlation of smoking with demographic factors, occupational stressors and life events was evaluated. The results of logistic regression analysis showed that even after adjusting for the confounding factors, cigarette smoking was significantly correlated with age, sex, level of education, job control and life events (P<0.05). The results showed that of occupational and non-occupational stressors, only job control was correlated with cigarette smoking. Non-occupational stressors had greater effect on cigarette smoking. Consideration of both non-occupational and occupational stressors can enhance the success of smoking control programs. On the other hand, a combination of smoking control and stress (occupational and non-occupational) control programs can be more effective than smoking cessation interventions alone.

We study the effects of low concentrations of mercury vapour on the nervous system of a group of eleven workers of a chloroalkali plant exposed to it. Twenty-three non-exposed workers in the same factory were used as control group. We used clinical and analytic explorations, psychometric tests and evoked potentials to evaluate the subjects. The average Hg in urine of the exposed group was 41.74 micrograms/gr creatinine and the average of the non-exposed group as 9.71 mu/yr. In the exposed group the evoked potentials have found a slowing-down of conduction in all the nervous paths studied (optical, auditive and somatosensory) and in the latency of P300 wave, although this was not statistically significant compared to the control group. Of the psychometric test used, only Rey's Complex Figure Test showed deterioration in the visual memory subtest of the exposed group (p < 0.05) compared to the control group, although in Wechsler's digit span test lower scores were obtained which were close to being statistically significant comparing the averages of the two groups (0.05 < p < 0.051). Bearing in mind these results we think that the amounts of Hg in urine and TLV-TWA (50 micrograms/gr creatinine and 50 micrograms/m3 respectively) accepted by most authors as innocuous should be reduced.

For the past decades, in a world of high competition, firms struggle to regain an advantage over foreign competition. Thus, new management trends, usually based on price reduction, high quality products and speed production are now part of strategic reorganization plans of high impact on work organization particularly in terms of large demands put on workers, and take a heavy toll on workers. Thus the incidence of mental health problems in the work place has risen sharply in recent years and currently counts as one of the leading causes of work absenteeism. A study based on the psychodynamic of work was conducted among machine operators working in a high-technology company in the aviation sector. Important management and technological transformations were recently introduced in the factory. The content analysis of the study shows that the work organization places the operator in a double bind situation. They are caught between an injunction where the capacity of making a high quality product is directly opposed to that demanding speed production. Moreover, severe and arbitrary sanctions are applied when the operators do not comply with either injunction. The operators are put in a deadlock situation that creates fear and anxiety. They are obliged to turn to defensive psychological strategies such as individualism and cheating. Those defensive strategies have negative impacts on social relationships.

Language barriers are often cited as a factor contributing to ethnic inequalities in occupational health; however, little information is available about the mechanisms at play. The authors describe the multiple ways in which language influences occupational health in a large garment factory employing many immigrants in Montreal. Between 2004 and 2006, individual, semi-structured interviews were conducted with 15 women and 10 men from 14 countries of birth. Interviews were conducted in French and English, Canada's official languages, as well as in non-official languages with the help of colleague-interpreters. Observation within the workplace was also carried out at various times during the project. The authors describe how proficiency in the official languages influences occupational health by affecting workers' ability to understand and communicate information, and supporting relationships that can affect work-related health. They also describe workers' strategies to address communication barriers and discuss the implications of these strategies from an occupational health standpoint. Along with the longer-term objectives of integrating immigrants into the linguistic majority and addressing structural conditions that can affect health, policies and practices need to be put in place to protect the health and well-being of those who face language barriers in the short term.
