To investigate the characteristics and changing trend of occupational hazards in the working environment of a foundry plant from 1987 to 2010. The foundry plant of a large-scale automobile company in Hubei Province, China was chosen as the study site. The data on occupational hazards in the working environment of the foundry plant in the past years were collected, and additional measurements were performed. The means and geometric means of the concentrations of occupational hazards were calculated. The characteristics and changing trend of occupational hazards from 1987 to 2010 were presented. There were dust, chemical, and physical occupational hazards in the working environment of the foundry plant, with silica dust, noise, and heat stress as the main ones. Dust, mainly silica dust, is found in all aspects of foundry. The mean concentration of silica dust was high (3.2∼8.2 mg/m(3)), exceeding the national occupational exposure limit (1 mg/m(3)). The mean concentrations of silica dust varied across different types of work, with higher levels in cast shakeout and finishing, overhead crane operation, and sand preparation. The mean concentration of respirable dust in the foundry plant was low (0.38 mg/m(3)), not exceeding the national occupational exposure limit (0.7 mg/m(3)). There were high concentrations of grinding wheel dust (10.6 mg/m(3)) and welding fume (5.7 mg/m(3)) in cast shakeout and finishing, exceeding the national occupational exposure limit (8 and 4 mg/m(3)). Coal dust was mainly found in melting as well as cast shakeout and finishing, with higher concentration in the former (4.7 mg/m(3). The main chemical occupational hazard in the environment of the foundry plant was formaldehyde (1.23 mg/m(3)), exceeding the national occupational exposure limit (0.5 mg/m(3)). The concentrations of ammonia, phenol, metal fume, sulfur dioxide, hydrogen sulfide, and phosphine in the foundry plant were low. The mean concentration of polycyclic aromatic hydrocarbons was 0.1405 µg/m(3), with a higher level in pouring. The main physical occupational hazards in the working environment of the foundry plant were noise and heat stress. Noise, mainly steady noise, was distributed in all workshops of the foundry plant, with a mean intensity of 85.1 db (A). Noise levels varied across different types of work, higher in cast shakeout and finishing (89.3 db (A)) and moulding (85.4 db (A)). Heat stress mainly existed in overhead crane operation (35.1°C), pouring (33.3°C), and melting (32.8°C). Dust, chemical, and physical occupational hazards co-existed in the working environment of the foundry plant. High concentration of dust was widely distributed in many workshops and across many types of work, but the dust concentration showed a downward trend. Chemical occupational hazards included ammonia, phenol, hydrogen sulfide, and metal fume, most at low concentrations. High-intensity noise was widely distributed in all working positions of foundry process and mainly from equipment operation, collision between parts, and gas injection. High-intensity heat stress mainly existed in overhead crane operation, pouring, and melting.

Foundry work is a risk factor for lung cancer; however, the association with welding is unclear, as smoking is common among metalworkers and may mask the relationship. We evaluated whether history of welding and foundry work, independently and jointly, and employment duration were associated with lung cancer risk in heavy smokers. We analysed data from the National Lung Screening Trial, a prospective randomised trial of 53 454 heavy smokers (>30 pack-years) in the USA. Cox regression models were used to estimate the HRs and 95% CIs of medically/histologically confirmed incident lung cancer during the follow-up period (2002-2009) in relation to history and duration of welding and foundry work assessed via questionnaires, adjusted for screening arm, component study, sex, age, race/ethnicity, education, smoking status and pack-years, body mass index and personal/family medical history. There were 2034 incident lung cancer cases throughout the follow-up. Increasing years of employment in welding (p-trend =0.039) and foundry work (p-trend =0.005) were related to increased lung cancer risk among heavy smokers. Having ever been employed (≥1 yr) as either a welder or foundry worker alone was associated with non-significant increased risks of lung cancer (HR=1.12 (95% CI 0.91 to 1.37) and HR=1.09 (95% CI 0.85 to 1.39), respectively). Further, there was a joint-effect in that those who were ever employed in both occupations had significantly increased risks (HR=1.48 (95% CI 1.08 to 2.04)). Our findings provide further evidence that exposure to welding/metal fumes may be associated with elevated lung cancer risk. NCT00047385. Published by the BMJ Publishing Group Limited.

The Occupational Disease Surveillance System (ODSS) was established in Ontario, Canada by linking a cohort of workers with data created from Workplace Safety and Insurance Board (WSIB) claims to administrative health databases. The aim of this study was to use ODSS to identify high-risk industry and occupation groups for lung cancer in Ontario. Workers in the WSIB lost time claims database were linked to the Ontario Cancer Registry using subjects' health insurance numbers, name, sex, birthdate and death date (if applicable). Several occupations and industries known to be at increased risk were outlined a priori to examine whether ODSS could replicate these associations. Age-adjusted, sex-stratified Cox proportional hazard models compared the risk of lung cancer within one industry/occupation versus all other groups in the cohort. Workers with a lung cancer diagnosis prior to cohort entry were excluded for analysis, leaving 2 187 762 workers for analysis. During the 1983 to 2014 follow-up, 34 661 workers in the cohort were diagnosed with lung cancer. Among expected high-risk industries, elevated risks were observed among workers in quarries/sand pits and construction industries for both sexes, and among males in metal mines, iron foundries, non-metallic mineral products industries and transportation industries. Excess risk was also observed among occupations in drilling/blasting, other mining/quarrying, mineral ore treating, excavating/grading/paving, truck driving, painting, bus driving and construction. This current surveillance system identified several established high-risk groups for lung cancer and could be used for ongoing surveillance of occupational lung cancer in Ontario. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Rogaczewska, T; Matczak, W

1985-01-01

By stationary measurements the levels of cadmium oxide aerosols concentrations in air at particular workplaces related to cadmium production at non-ferrous metals mill have been determined. High concentrations of that compound have been found at such technological operations as unloading of cadmium-bearing raw materials, batching of cadmium sponge in the induction furnace and casting of fused cadmium into moulds. With the personal dosimetry technique, concentrations of that compound in the workers' breathing zone have been determined. Those were within 0.16-1.84 mg/m3, so--above the TLV values. However, those concentrations do not necessarily reflect the occupational exposure magnitude, as the workers had respirators.

Workers exposed to heavy manual material handling (MMH) in a hot working environment succumb to severe physical stress and psychological stress. (1) Recognize the heat load at workplaces of ceramic industry and iron industry, and (2) comparatively examine the characteristics of self-reported physiological responses and heat-health perception among these workers. Cross-sectional prospective study. Workplace microclimate in the ceramic industry and iron industry was monitored. An ergonomic checklist and a questionnaire was used to record self-reported workers' perceptions toward heat stress at workplace (ceramic workers N = 321, iron foundry workers N = 253). The prevalence rates of subjective symptoms among workers of both the industries were compared. Chi-square test was used to examine the association between stressors and health complaints at a significance level set at P < 0.05. Iron foundries recorded higher mean ambient temperature (43.4 ± 3.7°C) and wet-bulb globe temperature (WGBT) index (31.5 ± 0.7°C) as compared to ceramic industries (39.9 ± 3.3°C and 28 ± 1.5°C, respectively). Heavy sweating, elevated body temperature, sleeplessness, excessive thirst, muscular discomforts, and fatigue were prime symptoms recorded among workers of both industries. Skin-related disorders (red face, dry skin, bumps, itching) were significantly higher among iron foundry workers, whereas sleeplessness, high blood pressure, heavy sweating, kidney stone, decreased urination, muscular discomforts, and fatigue were significantly more among ceramic workers. Young workers reported more sweating and fatigue than older workers. A hot work climate and heavy manual labor designate ceramic and iron industries as arduous. Direct contact with hot surface and continuous MMH in tandem with the mechanical pace of production process makes work in ceramic industries more difficult than iron foundries.

Global competition in manufacturing sector demand higher productivity levels. In this context, workers in this sector are set with high output targets, leading to job strain. In addition to the strain, hazardous conditions also prevail in some of the manufacturing processes like foundry activities. This paper attempts to appraise the prevalence of job strain among foundry shop floor workers in India with the help of Demands-Control model [8]. In this study, data was collected through a survey using 49-item Job Content Questionnaire (JCQ) [9], a widely used and well-validated test for job strain. Then the data was subjected to statistical analysis after ascertaining the reliability. This survey has revealed that 25% of workers in foundry were experiencing high job strain. Hazardous working conditions, limited decision making authority, etc. appear to be the main contributing factors for the higher levels of strain.

Background: Crystalline silica is a human carcinogen and its use is widespread among construction, mining, foundries, and other manufacturing industries. Purpose: To evaluate occupational exposure to crystalline silica in Italy. Methods: Data were collected from exposure registries and descriptive statistics were calculated for exposure-related variables. The number of potentially exposed workers was estimated in a subset of industrial sectors. Linear mixed model analysis was performed to determine factors affecting the exposure level. Results: We found 1387 cases of crystalline silica exposure between 1996 and 2012. Exposure was most common in construction work (AM = 0.057 mg/m3, N = 505), and among miners and quarry workers (AM = 0.048 mg/m3, N = 238). We estimated that 41 643 workers were at risk of exposure in the selected industrial sectors during the same period. Conclusions: This study identified high-risk sectors for occupational exposure to crystalline silica, which can help guide targeted dust control interventions and health promotion campaigns in the workplace.

Silicosis is an occupational lung disease which is caused by inhalation and accumulation of crystalline silica particles in the lung. It commonly occurs in workers involved in quarrying, mining, sandblasting, tunneling, foundry work, and ceramics. Pneumothorax is one of the complications of silicosis with pleural involvement. The occurrence of pneumothorax in a patient with silicosis is a rare event, but it may be fatal. The rate of pneumothorax recurrence in silicosis is usually low. We report a case of recurrent secondary spontaneous pneumothorax in silicosis.

To analyze systematically the characteristics of occupational hazards in the foundry, and provide precise data for epidemiology studies and control of occupational hazards in the foundry. Data of airborne dust, chemical occupational hazards and physical occupational agents in environment in the foundry from 1978 to 2008 were dynamically collected. Mean concentration and intensity (geometric mean) of occupational hazards were calculated by job in different years. Main occupational hazards in the foundry were silica, metal fume, noise and heat stress. Silica existed in all of main jobs. The mean concentration of silica before 1986 was an extremely high level of 8.6 mg/m(3), and then remarkably dropped after 1986, with the level of 2.4 mg/m(3) from 1986 to 1989, 2.7 mg/m(3) from 1990 to 2002 and 2.7 mg/m(3) from 2003 to 2008. The trend of silica concentrations by job was consistent with that in general. Silica concentrations among jobs were significantly different, with highest level in melting (4.4 mg/m(3)), followed by cast shakeout and finishing (3.4 mg/m(3)), pouring (3.4 mg/m(3)), sand preparation (2.4 mg/m(3)), moulding (2.1 mg/m(3)) and core-making (1.7 mg/m(3)). Concentration of respirable dust in pouring was highest (2.76 mg/m(3)), followed by cast shakeout and finishing (1.14 mg/m(3)). Mean concentration of asbestos dust in melting was a relative high level of 2.0 mg/m(3). In core-making and sand preparation, there existed emission production of adhesive, with mean concentrations as followed, ammonia (5.84 mg/m(3)), formaldehyde (0.60 mg/m(3)), phenol (1.73 mg/m(3)) and phenol formaldehyde resin (1.3 mg/m(3)) also existed. Benzene and its homologues existed in cast shakeout and finishing, and the level of benzene, toluene, xylene was 0.2 mg/m(3), 0.1 mg/m(3) and 1.3 mg/m(3), respectively. In pouring and melting, there existed chemical occupational hazards, including benzo(a) pyrene, metal fume (lead, cadmium, manganese, nickel, chromium) and gas(hydrogen sulfide, phosphine, sulfur dioxide, carbon monoxide). Mean concentration of benzo(a) pyrene was a low level of 1.80 x 10(-4) microg/m(3). Physical occupational agents in the foundry were noise, heat stress and vibration. Intensity of heat stress was high in melting, pouring and cast shakeout and finishing, with the level of 30 degrees C, 29 degrees C and 26 degrees C, respectively. Noise was high in cast shakeout and finishing and core-making, with the level of 93.1 dB(A) and 89.5 dB(A), respectively. Vibration existed in core-making and cast shakeout and finishing. Compulsory postures included long standing, seating and bowing. Occupational hazards in environment of the foundry are diversified and their concentrations exceed permissible exposure limits stipulated by the national occupational hygienic standards. High-concentrations of dust, metal fume, low-concentrations of variety of chemicals, high-intensity of noise and vibration, heat stress, and harmful compulsory posture, and so on all co-exist in the foundry. Control and protective measures should be strengthened.

Occupational lead poisoning in Ohio: surveillance using workers' compensation data.

Seligman, P J; Halperin, W E; Mullan, R J; Frazier, T M

1986-11-01

To determine the utility of workers' compensation (WC) data in a system for the surveillance of occupational lead poisoning, we reviewed workers' compensation claims for lead poisoning in Ohio. For the period 1979 through 1983, 92 (81 per cent) of the 114 claims attributed to lead met our case definition of lead poisoning. The likelihood that a company had a case of lead poisoning was strongly correlated with the number of claims against the company. Thirty companies accounted for the 92 cases; two companies accounted for 49 per cent of these. Inspection by the Occupational Safety and Health Administration (OSHA) occurred at 14 of these companies, all of which were cited for violations of the OSHA lead standard. Comparison of the Standard Industrial Classification (SIC) codes for the 14 companies inspected by OSHA with the 15 companies not inspected by OSHA revealed that OSHA inspected battery manufacturers, non-ferrous foundries, secondary smelters, and primary lead smelters, but not bridge painters, manufacturers of electronic components, mechanical power transmission equipment, pumps, and paints, nor a sheriff's office where firing range slugs were remelted to make new bullets. Neither the number of cases of lead poisoning at a company nor the size of a company was related to the likelihood of being inspected by OSHA. Claims for WC appear to be a useful adjunct to an occupational lead poisoning surveillance system; their usefulness should be compared to that of other systems such as laboratory reports of elevated blood lead levels in adults.

In European Union every day millions of employees are exposed to noise at work and the risk this can entail. this study presents the sound spectrum in Iasi heavy industry: metal foundries industry, punching and embossing of metal sheets, cold and hot metal processing. it was used a type 2 Sound Level Meter (SLM) and the considered value was the average value over 10 test values in 10 consecutive days for each octave band in common audible frequency range. It is obviously that the large values of sound intensities in the most of frequency octave band exceed maximum admissible and legal values. The study reveals the necessity of hardware, medical and managerial measures in order to reduce the occupational noise and to prevent the hearing acuity damage of the workers.

Polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) have been reported as possible carcinogenic hazards to humans. However, epidemiological studies on their carcinogenic roles are limited. The current study was designed to determine the concentrations and characteristics of PCDD/Fs and evaluate their association with cancer mortality in exposed workers in one automobile foundry factory. PCDD/F levels in factory and surrounding environment were analyzed through air and settling dust sampling. The cancer mortalities among workers in this foundry factory were calculated using data from a cohort study. The results showed that the PCDD/F concentrations of air in workplace ranged 0.36-2.25 pg World Health Organization-Toxic Equivalent (WHO-TEQ) Nm(-3) (average 1.01 pg WHO-TEQ Nm(-3)), which were 1.16-7.26 times higher than those outside the factory. The PCDD/F concentrations of settling dust in the workplace ranged 3.34-18.64 pg WHO-TEQ g(-1) (average 8.25 pg WHO-TEQ g(-1)), which were lower than those just outside the factory (average 16.13 pg WHO-TEQ g(-1)). Furthermore, a cohort study of workers in this factory with average follow-up of 24.52 years showed that cancer was the leading cause of death, with significant elevated mortality (standardized mortality ratio (SMR)=1.70, 95% confidence interval (CI): 1.35-2.13) among workers, when compared with Chinese national mortality. The cancer mortality among front-line workers was increased significantly (adjusted relative risk (RR)=1.73, 95% CI: 1.14-2.60), particularly among melting and casting workers, when compared with that among assistant workers. Our results indicated that there was a dose-response relationship between PCDD/F exposure and cancer mortality among foundry workers. Copyright © 2012 Elsevier B.V. All rights reserved.

Nasal cancer in England and Wales: an occupational survey.

Acheson, E D; Cowdell, R H; Rang, E H

1981-01-01

A national survey of the incidence of nasal cancer in England and Wales during the period 1963-7 with special reference to occupation confirmed the well-known increases in incidence of nasal cancer in cabinet makers and wood machinists, together with the absence of any significant increase in carpenters and joiners, and the increases in boot and shoe operatives and repairers, and in nickel smelters in South Wales. The significant excesses of cases found among coalminers, furnacemen in the gas, coke, and chemical industry, and furnacemen and labourers in foundries may be associated with exposure to coal and coke dust or may be spurious. No excess of nasal cancer was found among male textile workers. Excesses of uncertain significance were found among tailors and dressmakers, bakers and pastry cooks, and printers. Apart from the well-known relationships between adenocarcinoma and work in the furniture and footwear industries there is no definite indication in this survey of any association between a particular histological type of nasal tumour and occupation in England and Wales.

Little is known about the distribution by occupation of chronic illness, disability, morbidity, and lifestyles which put health at risk. To provide a map of the social inequalities in various dimensions of health and lifestyle by social class and for specific occupational groups. To formulate a hypothesis about the mechanisms which generate these inequalities. Prevalence rate ratios and prevalence odds ratios of perceived health, chronic illness, disability, absenteeism, trauma, smoking, and obesity calculated with data from the 1999-2000 Italian ISTAT (Central Statistics Institute) health survey; the study population includes adults (aged over 18 years) employed, or searching for a job, or withdrawn from the workforce. Among workers in manual unskilled labour, construction and agriculture are noted for worse health and more unhealthy lifestyles than average. For example, perceived bad health is more widespread among agricultural labourers (OR = 1.63), masons and construction machine operators (OR = 1.75), transport drivers (OR = 1.40), male caretakers, custodians, janitors and domestic help (OR = 1.46), electro-technicians (OR = 1.44), leatherworkers and shoemakers (OR = 3.58), miners and quarrymen (OR = 2.60), earthenware and stone workers (OR = 2.14), garment and furnishings workers (OR = 1.86); in female workers excess risk for perceived bad health was present among agricultural labourers (OR = 2.08), caretakers, custodians, janitors and domestic helpers (OR = 1.49), waitresses, cooks and bartenders, (OR = 1.44), and textile workers (OR = 1.67). Smoking was more widespread among chemical workers (OR = 1.41), and in miners and quarrymen (OR = 1.30). An excess risk of smoking of 20-25% was evident in spinners, weavers and finishers; masons, (and) builders; waiters, cooks and bartenders; garment and furnishings workers; porters and warehouse workers. The risk was 10% higher among foundry workers and forgers, plumbers, carpenters and welders, and transport drivers. Among women the propensity to smoke was higher among waitresses, cooks and bartenders (OR = 1.37), cleaners, commerce and service workers (OR = 1.22). Other occupational groups with an increased smoking prevalence, where women were less represented, included: chemical workers (OR = 2.25), butchers (OR = 1.97), postwomen (OR = 1.58), plastics workers (OR = 1.56), shippers (OR = 1.37). It can be hypothesized on the one hand that there are factors and mechanisms common to the various occupational groups belonging to the same social class; on the other, there are factors and mechanisms specific to certain occupational categories. The latter can generate specific health subcultures. A greater integration between qualitative and quantitative research is recommended, which would yield better explanations of the observed inequalities.

Amines as occupational hazards for visual disturbance

PubMed Central

JANG, Jae-Kil

2015-01-01

Various amines, such as triethylamine and N,N-dimethylethylamine, have been reported to cause glaucopsia in workers employed in epoxy, foundry, and polyurethane foam industries. This symptom has been related to corneal edema and vesicular collection of fluid within the corneal subepithelial cells. Exposure to amine vapors for 30 min to several hours leads to blurring of vision, a blue-grey appearance of objects, and halos around lights, that are probably reversible. Concentration-effect relationships have been established. The visual disturbance is considered a nuisance, as it could cause onsite accidents, impair work efficiency, and create difficulties in driving back home. Occupational exposure limits have been established for some amines, but there is shortage of criteria. Volatility factors, such as vapor pressure, should be considered in industrial settings to prevent human ocular risks, while trying to reduce levels of hazardous amines in the atmosphere.

Work-related musculoskeletal disorders, job stressors and gender responses in foundry industry.

PubMed

Sharma, Rohit; Singh, Ranjit

2014-01-01

The main aim of this paper was to identify job stressors, gender responses and association of psychosocial work stressors with prevalence of work related musculoskeletal disorders (MSDs) among foundry workers. The data were obtained with ergonomics checklist using Likert scale. The results of this study showed a high prevalence of MSDs among workers. The male workers were more prone to pain in neck while the female workers were more prone to MSDs in upper back and shoulders. Correlation analysis showed significant relationship of dimensions of work aspects with pain and discomfort. It proved that the work-related MSDs are the results of interaction of multiple stressors associated with work and work environment, and other personal factors. ANOVA indicated that the perception of work aspects as stressors differed significantly between male and female workers.

Critical body temperature profile as indicator of heat stress vulnerability.

Extreme climatic heat is a major health concern among workers in different occupational pursuits. People in the regions of western India confront frequent heat emergencies, with great risk of mortality and morbidity. Taking account of informal occupational groups (foundry and sheet metal, FSM, N=587; ceramic and pottery, CP, N=426; stone quarry, SQ, N=934) in different seasons, the study examined the body temperature profiling as indicator of vulnerability to environmental warmth. About 3/4th of 1947 workers had habitual exposure at 30.1-35.5°C WBGT and ~10% of them were exposed to 38.2-41.6°C WBGT. The responses of FSM, CP and SQ workers indicated prevailing high heat load during summer and post-monsoon months. Local skin temperatures (T(sk)) varied significantly in different seasons, with consistently high level in summer, followed by post-monsoon and winter months. The mean difference of T(cr) and T(sk) was ~5.2°C up to 26.7°C WBGT, and ~2.5°C beyond 30°C WBGT. Nearly 90% of the workers had T(cr) within 38°C, suggesting their self-adjustment strategy in pacing work and regulating T(cr). In extreme heat, the limit of peripheral adjustability (35-36°C T(sk)) and the narrowing down of the difference between T(cr) and T(sk) might indicate the limit of one's ability to withstand heat exposure.

Mortality was analyzed for an automotive engine foundry and machining complex, with process exposures derived from department assignments. Logistic regression models of mortality odds ratios (ORs) were calculated for 2546 deaths, and numbers of work-related deaths were estimated. Lung cancer mortality in the foundry was increased where cleaning and finishing of castings was performed (OR, 1.7; 95% CI, 1.15 to 2.4 [at mean exposure duration of exposed cases]) and in care-making after 1967 (OR, 1.5; 95% CI, 1.11 to 2.0). Black workers had excess lung cancer mortality in machining heat-treat operations (OR, 2.5, 95% CI, 1.4 to 4.3) and excess nonmalignant respiratory disease mortality in molding (OR, 2.5; 95% CI, 1.16 to 5.5) and core-making (OR, 2.7; 95% CI, 1.25 to 5.8). Stomach cancer mortality was elevated among workers with metalworking fluid exposures in precision grinding (OR, 2.4; 95% CI, 1.14 to 5.1). Heart disease mortality was increased among all workers in molding (OR, 1.6; 95% CI, 1.09 to 2.3), as was stroke mortality among workers exposed to metalworking fluids (OR, 1.8; 95% CI, 1.22 to 2.7). Malignant and nonmalignant liver disease mortality was elevated in assembly/testing and precision grinding. In this modern foundry, 11% of deaths were estimated to be work-related despite it's being largely in regulatory compliance over its 40-year existence. Machining plant exposures accounted for 3% or more of deaths there.

Uranium particles within the respirable size range pose a significant hazard to the health and safety of workers. Significant differences in the deposition and incorporation patterns of aerosols within the respirable range can be identified and integrated into sophisticated health physics models. Data characterizing the uranium particle size distribution resulting from specific foundry-related processes are needed. Using personal air sampling cascade impactors, particles collected from several foundry processes were sorted by activity median aerodynamic diameter onto various Marple substrates. After an initial gravimetric assessment of each impactor stage, the substrates were analyzed by alpha spectrometry to determine the uranium content of each stage. Alpha spectrometry provides rapid non-distructive isotopic data that can distinguish process uranium from natural sources and the degree of uranium contribution to the total accumulated particle load. In addition, the particle size bins utilized by the impactors provide adequate resolution to determine if a process particle size distribution is: lognormal, bimodal, or trimodal. Data on process uranium particle size values and distributions facilitate the development of more sophisticated and accurate models for internal dosimetry, resulting in an improved understanding of foundry worker health and safety.

A proportionate mortality ratio (PMR) study was conducted using data on workers from three local unions representing an integrated automobile factory composed of forge, foundry, and engine (machine and assembly) plants. Ninety four percent of the death certificates were obtained for all active and non-active workers who died during the period 1 January 1970 to 31 December 1979 and were vested in union and company benefit programmes. Observed numbers of deaths were compared with expected numbers based on two standards, the proportionate mortality among men in the United States 1970-9 and among men in Erie County 1975. There was close agreement between the number of observed and expected deaths by either standard of comparison among white auto workers in the forge and foundry plants. Valid analyses of cause specific mortality among non-whites could be conducted for the foundry plant only. Although there was raised PMR for deaths due to diseases of the circulatory system using the Erie County standard, none of the other cause specific PMRs was significant. Although based on small numbers, the risk of cancer of the lung was significantly high in non-whites under age 50 in the foundry (PMR = 2.6; p less than 0.05). The cause specific PMRs for whites in the engine plant were statistically significant for malignant neoplasms (1.2) and all external causes (0.62) based on the US white male standard. Analysis of cancer specific mortality among white men in the machining/assembly plant showed significant excesses for cancer of the digestive system (PMR=1.5), particularly of the liver (PMR=2.6) and pancreas (PMR=1.9); cancers of the respiratory system (PMR=1.4 using the Erie County standard); and cancer of the urinary bladder (PMR=2.3). Workers employed for more than 20 years showed statistically increased mortality ratios for cancers of the digestive system (1.9), particularly cancer of the pancreas (2.3) and cancer of the rectum (2.8). Individuals whose employment began during or before 1950 exhibited increased PMRs for cancers of the digestive organs (1.8), particularly of the pancreas (2.5) and of the bladder (3.4). Workers whose employment began after 1950, on the other hand, exhibited raised PMRs for cancers of the respiratory system (1.5) and of the kidney (3.2). Since the foundry and forge plants did not start production until 1955, mortality associated with those work settings may be greater in the future. PMID:3970876

In a 3-month period, three men who had worked for 5 to 19 years as welders or grinders of steel castings in a foundry acquired pneumonia caused by Acinetobacter calcoaceticus variety anitratus serotype 7J. Two of the men died, and postmortem examination showed mixed-dust pneumoconiosis with iron particles in the lungs. A calcoaceticus variety anitratus serotype 7J was isolated from the air in the foundry but the source was not found. The prevalence of antibody titers of 64 or greater to the 7J strain was significantly higher among foundry workers (15%) than among community controls (2%) (p less than 0.01).more » Sampling showed that the concentrations of total and metallic particles (especially iron) and of free silica in air inhaled by welders and grinders at the foundry frequently exceeded acceptable levels. These findings suggest that chronic exposure to such particles may increase susceptibility to infection by this organism, which rarely affects healthy people.« less

Vibration syndrome in chipping and grinding workers.

PubMed

1984-10-01

A clear conclusion from these studies is that vibration syndrome occurs in chipping and grinding workers in this country and that earlier reports that it may not exist were probably inaccurate. The careful selection of exposed and control groups for analysis strengthens the observed association between vibration syndrome and the occupational use of pneumatic chipping hammers and grinding tools. In the foundry populations studied the vibration syndrome was severe, with short latencies and high prevalences of the advanced stages. The shipyard population did not display this pattern. This difference can be attributed to variations in work practices but the more important factor seems to be the effect of incentive work schedules. Comparisons of groups of hourly and incentive workers from the shipyard and within foundry populations consistently demonstrated that incentive work was associated with increased severity of vibration syndrome. Excessive vibration levels were measured on chipping and grinding tools. Of the factors studied, reduction of throttle level decreased the vibration levels measured on chipping hammers. For grinders, the working condition of the tool affected the measured vibration acceleration levels. Grinders receiving average to poor maintenance showed higher vibration levels. The results of objective clinical testing did not yield tests with diagnostic properties. To date, the clinical judgment of the physician remains the primary focus of the diagnosis of vibration syndrome. A number of actions can be taken to prevent vibration syndrome. Preplacement medical examinations can identify workers predisposed to or experiencing Raynaud's phenomenon or disease. Informing employees and employers about the signs, symptoms, and consequences of vibration syndrome can encourage workers to report the condition to their physicians promptly. Engineering approaches to preventing vibration syndrome include increased quality control on castings to reduce finishing time and automation of the finishing process. Tool manufacturers can contribute by modifying or redesigning tools to reduce vibration. The technology to reduce vibration from hand tools exists but the engineering application is difficult. Vibration from chain saws has been reduced through changes in design and some companies have begun to redesign jackhammers, scalers, grinders, and chipping hammers. As these become available, purchasers can encourage manufacturers by selecting tools with antivibration characteristics. Vibration from tools currently in use can be controlled by periodically scheduled inspection and maintenance programs for vibrating tools.(ABSTRACT TRUNCATED AT 400 WORDS)

Objective: To assess characteristics of asbestos exposure in respiratory cancer patients in Lithuania. Methods. Information on occupational exposure to asbestos was collected by personal interviews and occupational characteristics were evaluated among 183 lung cancer and mesothelioma patients with cumulative asbestos exposure >=0.01 fibre years hospitalized at the Institute of Oncology, Vilnius. Additionally, some results of workplace air measurements were reviewed. Results. Cases with estimated cumulative exposure >=5 fibre years had worked mainly in the construction industry (49%), installation and maintenance (13%), foundry and metal products manufacturing (6%), heating trades and boilerhouses (6%) as fitters/maintenance technicians, construction workers, welders, electricians or foremen. Typical asbestos materials used by the patients were asbestos powder, asbestos cement sheets and pipes, asbestos cord, brake and clutch linings. Patients were exposed to asbestos when insulating boilers, furnaces, pipes in power stations, industrial facilities, ships, locomotives, buildings, while covering and repairing roofs, at the asbestos cement plant or unloading asbestos products. Most patients with estimated cumulative exposure of >=0.01-4.9 fibre years worked as lorry, bus or tractor drivers and motor vehicle mechanics. In 2002-2007 workplace air asbestos concentrations exceeded the limit value of 0.1 f/cm3 in 11 samples out of 208 measurements. Conclusion. The results of this study indicate that since the 1960s occupational exposure to chrysotile asbestos was extensive in Lithuania.

In the production of building structures for high-rise buildings, the dangerous and harmful factors of foundry production include high concentrations of dust and harmful gases released at various stages of the process. Disperse and elemental compositions of dust determine the hygienic state of the working area of the foundry. According to experts, the presence of dust of less than 10 microns in size in the air increases the danger of getting occupational diseases, such as pneumoconiosis (silicosis), bronchitis, dermatitis, conjunctivitis. The determination of the granulometric composition of the powder sample provided was carried out by the laser diffraction method realized on a laser particle analyzer Fritsch NanoTec «ANALISETTE 22».

This article aimed to investigate the effect of heat stress on cognitive performance and the blood concentration of stress hormones among workers of a foundry plant. Seventy workers within the exposed (35 people) and unexposed (35 people) groups were studied. The wet bulb globe temperature (WBGT) index was measured for heat stress assessment. The cognitive performance tests were conducted using the Stroop color word test (SCWT) before and during working hours. For the assessment of the serum level of cortisol and the plasma level of adrenaline and noradrenaline, blood samples were taken during working hours from both groups. Only for SCWT III was there a significant relationship between heat stress and test duration, error rate and reaction time. The laboratory test results revealed significantly higher concentrations of cortisol, adrenaline and noradrenaline in the exposed subjects than in the unexposed group. There existed a positive correlation between cortisol, adrenaline, noradrenaline and WBGT index and also test duration and reaction time of SCWT III, and number of errors of SCWT I, SCWT II and SCWT III during work. Heat stress can lead to an increase in the blood level of stress hormones, resulting in cognitive performance impairment.

OBJECTIVES--To assess the acute and chronic ophthalmological effects of triethylamine exposure among foundry workers. METHODS--Ocular effects on people currently, previously, and never exposed to triethylamine in a foundry cold box were studied at two points in time. The initial phase included an ocular examination with a slit lamp to assess corneal health, a visual acuity test, and a questionnaire to assess vision symptoms. The follow up included measurements of corneal thickness with an ultrasonic pachymeter and the vision symptoms questionnaire before and after the shift and at the beginning and end of the week. Personal air measurements for triethylamine were also obtained during the follow up. RESULTS--The vision symptoms of blurriness, halos around lights, and blue hazy vision occurred more often in currently exposed workers than those previously or never exposed to triethylamine. Air concentrations of triethylamine ranged from < 0.33 mg/m3 to 20.3 mg/m3. Among currently exposed workers, symptoms were more common among those with exposure to > 10 mg/m3 of triethylamine (odds ratio (OR) = 3.0, 95% confidence interval (95% CI) 0.35-25.6). No differences in corneal thickness were found in currently or previously exposed workers and those never exposed. No increase in corneal thickness was found after v before the shift. CONCLUSION--Despite low concentrations of triethylamine and no corneal oedema, workers exposed to triethylamine reported vision symptoms. Possible explanations for these symptoms without corneal oedema are that triethylamine affects ciliary muscle function or that the corneal oedema was transient and not present when corneal thickness measurements were taken. No chronic effects were found in previously exposed workers. Further research is needed to elucidate the mechanism for the reported vision symptoms, which occurred below the current United States eight hour time weighted standard of 100 mg/m3 and the American Conference of Governmental Industrial Hygienists (ACGIH) recommended value at the time of our study of 40 mg/m3. We recommend that air concentrations be maintained to meet the current recommended ACGIH threshold of 4.1 mg/m3. PMID:7795757

There is an increasing need to evaluate concentrations of nanoparticles in occupational settings due to their potential negative health effects. The Nanoparticle Respiratory Deposition (NRD) personal sampler was developed to collect nanoparticles separately from larger particles in the breathing zone of workers, while simultaneously providing a measure of respirable mass concentration. This study compared concentrations measured with the NRD sampler to those measured with a nano Micro Orifice Uniform-Deposit Impactor (nanoMOUDI) and respirable samplers in three workplaces. The NRD sampler performed well at two out of three locations, where over 90% of metal particles by mass were submicrometer particle size (a heavy vehicle machining and assembly facility and a shooting range). At the heavy vehicle facility, the mean metal mass concentration of particles collected on the diffusion stage of the NRD was 42.5 ± 10.0 µg/m3, within 5% of the nanoMOUDI concentration of 44.4 ± 7.4 µg/m3. At the shooting range, the mass concentration for the diffusion stage of the NRD was 5.9 µg/m3, 28% above the nanoMOUDI concentration of 4.6 µg/m3. In contrast, less favorable results were obtained at an iron foundry, where 95% of metal particles by mass were larger than 1 µm. The accuracy of nanoparticle collection by NRD diffusion stage may have been compromised by high concentrations of coarse particles at the iron foundry, where the NRD collected almost 5-fold more nanoparticle mass compared to the nanoMOUDI on one sampling day and was more than 40% different on other sampling days. The respirable concentrations measured by NRD samplers agreed well with concentrations measured by respirable samplers at all sampling locations. Overall, the NRD sampler accurately measured concentrations of nanoparticles in industrial environments when concentrations of large, coarse mode, particles were low.

There are many studies done to identify the genetic hazard from occupational exposure of workers, but rather little is known about genetic effects in inhabitants of polluted areas. The aim of the study was to examine chromosome aberrations, sister chromatid exchanges and number of micronuclei in lymphocytes of persons living in the close vicinity of a large metallurgical plant. The results were compared with those obtained for the inhabitants of a village located 40 km from the city of Cracow and from the plant. An increased incidence of chromosome aberrations (0.66-4.66%, control 0.78%), sister chromatid exchanges (mean 9.73, control: 6.0) was found in the group living near the steel foundry. The paper also includes some data on measurements of the air pollution in the Nowa Huta region as well as on the amounts of heavy metals in vegetables in this region. Environmental pollution is worsening.

Loskutov, D V; Khamitova, R Ya

Review of the literature shows that currently there is an accumulation of data on the genetic determination of individual susceptibility to adverse industrial factors. Material of the research were high molecular DNA samples isolated from epithelial mouth scrapings in 99 foundry workers. Study of polymorphic variants of interleukin genes was performed by means of the analysis ofproducts of amplification of specific regions of the genome. Homozygous genotype TNF-a (-308A/G) was established to increase the relative risk of shaping of chronic respiratory diseases: with AA alleles - by 6.4 times and GG alleles - by 2.4 times, while the heterozygous genotype (AG) decreases - by 1. 9 times. Polymorphism of gene IL-1β (+3953 T / C) had no significance for the development of respiratory disease. Genotyping interleukins, involved in the inflammatory responses of the bronchopulmonary tract, can be considered as an element ofprimary prevention in industries with a high risk for shaping of respiratory diseases.

OBJECTIVES--To assess airflow limitation in workers exposed long term to metal dust, the prevalence of pleural plaques in those workers exposed in the past to asbestos, the influence of pleural plaques on lung function, and the possible association with airway disease caused by asbestos. METHODS--A cross sectional and longitudinal (seven year) survey of 494 long term (mean (SEM) 21(1) years) workers in a copper refinery was carried out from medical questionnaires, chest radiographs, and forced spirometry. RESULTS--The prevalence of lifetime non-smokers was 19%, current smokers 39%, and ex-smokers 42%. The prevalence of chronic obstructive pulmonary diseases (COPD) (forced expiratory volume in one second (FEV1) < 80% predicted) was 5%, small airway dysfunction (SAD) (maximal mid-expiratory flow (MMEF) < 60% predicted) was 7%, and this did not differ from the control population. The COPD and SAD were associated with cumulative smoking index but not with the cumulative work years at the plant or with any type of work at the plant. The mean (SEM) reduction of FEV1 was 20(7) ml in non-smokers, 26(4) ml in smokers, and 26(5) ml in ex-smokers (P > 0.05). In the smokers and ex-smokers with COPD, the loss of FEV1 was 53(10) (P < 0.02). The prevalence of pleural plaques was 11% (P < 0.0001); pleural plaques were found in older workers with known exposure to asbestos. The pleural plaques were circumscribed and associated with a non-significant 196 ml reduction in forced vital capacity (FVC) and non-significant reduction of FVC over time. The pleural plaques were not associated with COPD or SAD. The cumulative smoking index obtained by a technician did not differ from that by a chest physician. CONCLUSIONS--Despite exposures to asbestos that produced pleural plaques and exposures to metal dusts and foundry fumes the long term workers of this plant did not have excessive prevalence of COPD or SAD. The data suggest that low level long term exposure to metal dusts, gases, and foundry fumes do not necessarily cause respiratory dysfunction, circumscribed pleural plaques with low grades of width and extent do not reduce FVC significantly, and exposure to asbestos dust that produced pleural plaques does not necessarily produce airway dysfunction.

Objective: To investigate the prevalence of occupational diseases and treatment implementation in migrant workers in Hunan, China, and to provide a scientific basis for related departments to develop preventive and treatment measures and social security system for migrant workers. Methods: A retrospective investigation was performed in 2015 to collect the information of occupational diseases in migrant workers, and age, type of work, type of occupational disease, and implementation of employment injury insurance for occupation diseases were analyzed. Results: The migrant workers with occupational diseases accounted for 50.43% (11 280/22 368) of all patients with occupational diseases in Hunan, among whom 99.4% (11 212/11 280) were male workers. The mean age of migrant workers with occupational diseases was 55 years. The types of occupational diseases involved 6 categories such as occupational pneumoconiosis and occupational skin diseases, totaling 42 legal occupational diseases; 98.31% of all migrant workers (11 089/11 280) had occupational pneumoconiosis. The main types of work were underground coal miners (62.42%) , heading drivers (29.79%) , and haulage workers (2.20%) in coal mines and non-coal mines. A total of 27.25% migrant workers with occupational diseases (2 072/7 605) enjoyed employment injury insurance, and 20.84% (1 585/7 605) did not receive any medical or life compensations. Conclusion: The occupational diseases in migrant workers in Hunan are mainly pneumoconiosis, and a large proportion of those with occupational diseases do not enjoy implementation of treatment. Coal mines and non-coal mines are the high-risk areas for occupational diseases in migrant workers and should be the focus of prevention and control.

[On vibration hazards of chipping-hammer operators in an iron foundry. Part 2. Results of the hygienic control].

Harada, N; Matsumoto, T; Yamada, S; Kobayashi, F

1982-01-01

We previously reported that the working and health conditions of vibrating tool operators in an iron foundry were investigated in 1975 and vibration hazards were observed to occur frequently in workers operating chipping-hammers powered by compressed air. After that, we instituted medical treatment for the afflicted workers and improvement of working conditions in the foundry, and have performed annual medical examinations for four years. In this paper, the course of hygienic control and the change in the medical findings of twenty-four chipping-hammer operators are reported. 1. The following measures were taken to improve the working conditions of chipping-hammer operators and therapy for patients (Table 1): (1) The operating time of vibrating tools, including chipping-hammer, was limited to two hours per day. The casting process was improved to diminish the flashes that are the objects of chipping-hammer operation. For the purpose of reducing the vibration transmitted to the operator, a servo-arm that has a servomechanism for the chipping-hammer was developed and introduced. (2) Infrared lamps in the foundry and air curtains at the doorway were installed for keeping the chipping-hammer operating area warm. A warm room was set up in the foundry for providing warmth during rest periods and protective clothing against the cold was provided. (3) Workers who displayed health disturbances by medical examinations were treated during the cold season from November to April by periodic visits to the clinic or extended hospitalization, or transferred to job without vibration exposure, according to their stage of disease. Preventive treatment with vasodilator and bubble bath was performed in winter for the chipping-hammer operators. 2. In order to estimate the effect of these countermeasures, annual medical examinations were conducted in March 1975, March 1976, April 1977 and March 1978. Such subjective symptoms as Raynaud's phenomenon, finger numbness, finger listlessness, heavy-headedness, forgetfulness, irritability and hearing disorder showed a tendency for improvement, but other complaints did not (Tables 2-4). The improvement of Raynaud's phenomenon is considered to be due not merely to the countermeasures but also to reducing the chance of provocation and therefore the countermeasures should not be overestimated as a factor of recovery of vibration hazards. Of the functional tests, a tendency for improvement was recognized in sensory functions and peripheral circulatory functions, but not in motor functions (Tables 5, 6). However, the course of recovery was not fast and some advanced cases, especially those using chipping-hammers for more than ten years, showed less improvement after hospital treatment (Table 7, Fig. 1). This indicates the importance of hygienic control which enables vibration hazards patients to have early diagnosis and treatment. Furthermore, in order to eradicate the vibration hazards in the cast metal industry, a drastic reform of the finishing process is considered to be necessary.

Safety climate and occupational stress are related with occupational accident. The present study tried to identify the differences in safety climate and occupational stress according to occupational accidents experience and employment type (e.g., direct workers and subcontract workers). In this study, we conducted a survey using safety climate scale and Korean Occupational Stress Scale and classified the participants into four groups: direct workers working for accident-free departments, direct workers working for accident departments, subcontract workers working for accident-free departments, and subcontract workers working for accident departments for 2 years within the same workplace in the shipbuilding industry. The direct workers and subcontract workers showed diverse results in subscales of safety climate and occupational stress. This result is supported by existing studies; however, further study is necessary for more supporting evidence and elaborative methodological approach. The necessity of management for safety climate and psychosocial factor such as occupational stress for both direct workers and subcontract workers as a whole is suggested by this study.

Due to an increasing number of workers aged 50 years and above, the number of those employed is also on the rise, and those workers aged 50 and over has exceeded 50% of the total fatal occupational injuries. Therefore, it is necessary to implement the selection and concentration by identifying the characteristics of high-risk groups necessary for an effective prevention against and reduction of fatal occupational injuries. This study analyzed the characteristics of high-risk groups and the occupational injury fatality rate per 10,000 workers among the workers aged 50 and over through a multi-dimensional analysis by sex, employment status of workers, industry and occupation by targeting 4,079 persons who died in fatal occupational injuries from January 2007 to December 12. The share of the workers aged 50 years and above is increasing every year in the total fatal occupational injuries occurrence, and the high-risk groups include 'male workers' by sex, 'daily workers' by worker's status, 'craft and related-trades workers' by occupation, and 'mining' by industry. The most frequent causal objects of fatal occupational injuries of the workers aged 50 years and above are found out to be 'installment and dismantlement of temporary equipment and material on work platforms including scaffold' in the construction industry and 'mobile crane, conveyor belt and fork lifts' in the manufacturing industry.

What jobs are associated with the highest and lowest levels of cigarette use and of lung cancer? Are there gender differences in these jobs? Two data sets-the Epidemiological Follow-up to the National Health and Nutrition Examination Survey (NHEFS) and the California Occupational Mortality Study (COMS) were analyzed to answer these questions. For females, the broad occupations ranking from highest to lowest cigarette use in the NHEFS was: transportation operators, managers, craft workers, service workers, operatives, laborers, technicians, administrative workers, farm owners and workers, sales workers, no occupation, and professionals. The corresponding ranking for males was: transportation operators, no occupation, laborers, craft workers, service workers, technicians, and professionals. The highest-ranking jobs in the COMS were waitresses, telephone operators, and cosmetologists for women, and water-transportation workers, roofers, foresters and loggers for men. Teachers were especially low on all four lists. This study could not determine whether employment within any occupation encouraged smoking or if smokers selected certain occupations. PMID:8982527

The article covers evaluation of work strain in major and auxiliary occupations of by-product coke industry. The study results conclude that occupational activity of by-product coke industry workers, under exposure to occupational hazards, affects the workers' performance. Major occupations workers demonstrate higher level of functional strain of CNS, poor concentration of attention and lower ability to switch over, decreased general performance, vs. the auxiliary occupations workers who demonstrated increased cardiovascular and neuro-muscular strain due to occupational activity.

Studies examining workers' diet according to smaller occupational groups within "large occupational categories" are sparse. The aim of this study was to examine the potential differences in workers' diets based on the classification of workers into smaller occupational groups that comprise "large occupational categories". The subjects of this study were working fathers who had participated in the Japan Environment and Children's Study (N = 38,656). Energy and nutrient intake were calculated based on data collected from the Food Frequency Questionnaire. Occupations were classified according to the Japanese Standard Occupational Classification. Logistic regression analyses were performed to examine the adherence to current dietary recommendations within smaller occupational groups. In particular, significant differences were observed among the categorical groups of "professional and engineering workers", "service workers", and "agricultural, forestry, and fishery workers". In "professional and engineering workers", teachers showed higher odds of adherence to calcium intake recommendations compared with nurses (OR, 2.54; 95% CI, 2.02⁻3.14; p < 0.001). In "agricultural, forestry, and fishery workers", agriculture workers showed higher odds of adherence to calcium (OR, 2.15; 95% CI, 1.46⁻3.15; p < 0.001) and vitamin C (OR 1.90, 95% CI 1.31⁻2.74, p = 0.001) intake recommendations compared with forestry and fishery workers. These findings may be beneficial from a research perspective as well as in the development of more effective techniques to improve workers' diet and health.

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.

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.

Since 1989, blue-collar foreign workers have been permitted to work in Taiwanese industries. Most blue-collar foreign workers apply for jobs in Taiwan through blue-collar foreign workers' agencies. Because blue-collar foreign workers are not familiar with the language and culture in Taiwan, in occupational accident education and hazard prevention, the agencies play an important role in the coordination and translation between employees and blue-collar foreign workers. The purpose of this study is to establish the agencies' role in the occupational accidents education and hazard prevention for blue-collar foreign workers in Taiwan. This study uses a qualitative method-grounded theory-to collect, code, and analyze the data in order to understand the agencies' role in occupational accident education and hazard prevention for blue-collar foreign workers in Taiwan. The results show that the duty of agencies in occupational accident education and hazard prevention includes selecting appropriate blue-collar foreign workers, communicating between employees and blue-collar foreign workers, collecting occupational safety and health information, assisting in the training of occupational safety and health, and helping blue-collar foreign workers adapt to their lives in Taiwan. Finally, this study suggests seven important points and discusses the implementation process necessary to improve governmental policies. The government and employees should pay attention to the education/training of occupational safety and health for blue-collar foreign workers to eliminate unsafe behavior in order to protect the lives of blue-collar foreign workers.

[Croatian and international regulations on the protection and rights of workers exposed to asbestos at work].

PubMed

Zavalić, Marija; Macan, Jelena

2009-11-01

New regulations on the protection and rights of workers occupationally exposed to asbestos were introduced in Croatia in 2007 and 2008. They have been harmonised with the European Union (EU) and International Labour Organization (ILO) regulations, and make a step forward in safety at work, health protection, social rights, and pension schemes for Croatian workers occupationally exposed to asbestos. The 2007 Croatian regulation on the protection of workers from the risks related to exposure to asbestos at work defines and describes activities in which workers can be occupationally exposed to asbestos, defines the threshold value of asbestos in the air at work, defines valid methods for measurement of asbestos concentrations in the air, and establishes measures to reduce asbestos exposure at work or protect the exposed workers. Croatian law regulating obligatory health surveillance of workers occupationally exposed to asbestos from year 2007 defines activities and competent authorities to implement health surveillance of workers occupationally exposed to asbestos and to diagnose occupational diseases related to asbestos. This law also defines "occupational exposure to asbestos", and "occupational asbestos-related diseases", including asbestosis (pulmonary asbestos-related fibrosis), pleural asbestos-related disorders (plaques, pleural thickening, and benign effusion), lung and bronchial cancer, and malignant mesothelioma of serous membranes. These regulations have been harmonised with ILO, Directive 2003/18/EC amending Council Directive 83/477/EEC on the protection of workers from the risks related to exposure to asbestos at work, and with the Commission Recommendation 2003/670/EC concerning the European schedule of occupational diseases. The 2008 Croatian regulation on conditions of health surveillance, diagnostic procedures and criteria for confirmation of occupational asbestos-related diseases "defines the terms and the content of medical examination of workers exposed to asbestos, and criteria for the confirmation of occupational asbestos-related diseases which are harmonised with the Helsinki criteria acknowledged by ILO and EU, particularly concerning the level and length of exposure. Croatian law on compensation of workers occupationally exposed to asbestos from 2007 regulates compensation claims for workers with occupational asbestos-related disease, authorities competent to process these claims, and funds and coefficients for compensation payments. Accordingly, Croatia is responsible for compensation claims payment for workers with occupational asbestos-related disease. The 2007 law on conditions for entitlement to full pension for workers exposed to asbestos at work defines the conditions for fulfilling criteria for retirement pension for workers exposed to asbestos at work.

Occupational skin diseases and prevention among sanitation workers in China.

2015-09-01

Little research has been focused on the health status or the occupational protection awareness of sanitation workers. The policy recommendations on the occupational safety and health of sanitation workers based on the scientific research are also insufficient in developing countries like China. To study the incidence of dermatoses and the relevance with occupational exposure, protection awareness and protective measures among sanitation workers for better management and protection of the sanitation workers. 273 sanitation workers and 113 administrative staff from 11 streets of Wuhan were recruited. Dermatological problems were evaluated and recorded by physical examination. Occupational exposure, protection awareness, the use of protective equipments and personal history of skin disease were assessed by questionnaires. Compared with administrative staff, sanitation workers had much more occupational dermatological problems and had a much higher rate of harmful ultraviolet ray exposure. Young sanitation workers were more aware of occupational self-protection and a relatively higher rate of them using protective equipments compared with old ones. Exposure to multiple health hazards and the poor use of protective equipments are related to skin diseases in sanitation workers. Prejob training of self-protection and the use of protective equipments are recommended.

Tannery workers are at considerable risk of developing occupational contact dermatitis. Occupational skin diseases in tannery workers in newly industrialized countries have been reported, but neither the prevalence of occupational allergic contact dermatitis nor the skin-sensitizing agents were specifically examined in those studies. To assess the prevalence of occupational allergic contact dermatitis in Indonesian tanneries, identify the causative allergens, and propose a tannery work series of patch test allergens. A cross-sectional study in all workers at two Indonesian tanneries was performed to assess the prevalence of occupational contact dermatitis via a questionnaire-based interview and skin examination. Workers with occupational contact dermatitis were patch tested to identify the causative allergens. Occupational contact dermatitis was suspected in 77 (16%) of the 472 workers. Thirteen (3%) of these 472 workers were confirmed to have occupational allergic contact dermatitis. Potassium dichromate (9.2%), N,N-diphenylguanidine (5.3%), benzidine (3.9%) and sodium metabisulfite (2.6%) were found to be the occupationally relevant sensitizers. The sensitization pattern showed some differences from the data in studies reported from other newly industrial countries. We compiled a 'tannery work series' of allergens for patch testing. A number of these allergens may also be considered for patch testing in patients with (leather) shoe dermatitis. © 2012 John Wiley & Sons A/S.

Motor vehicle manufacturing and prostate cancer.

Brown, D A; Delzell, E

2000-07-01

The purpose of this investigation was to evaluate the relation between employment in motor vehicle manufacturing (MVM) and fatal prostate cancer. The study included 322 prostate cancer deaths occurring in 1973 through 1987 and 1,285 controls, selected from a cohort of 126,100 male MVM workers. Men employed in casting operations had an odds ratio of 1.5 (95% CI = 1. 1-2.0). The association was consistent across casting facilities and was attributable primarily to work in core and mold making (OR = 1.5, 95% CI = 1.1-2.2) and metal melting and pouring jobs (OR = 1.9, 95% CI = 1.0-3.6). Other results included ORs of 1.9 (95% CI = 1.0-3.7) for warehousing and distribution operations and 2.1 (95% CI = 1.2-3. 7) for electric and electronic equipment manufacturing. The latter two associations exhibited little internal consistency. The relationships seen in this study were weak and may have been due to chance. Core and mold making and metal melting and pouring foundry operations entail potential exposure to metal dusts and fumes, to polycyclic aromatic hydrocarbons (PAHs), and to other chemicals. However, associations between these exposures and prostate cancer have not been reported consistently, nor have other studies of foundry workers consistently noted an excess of prostate cancer.

Medical expenditures associated with nonfatal occupational injuries among immigrant and U.S.-born workers

PubMed Central

2012-01-01

Background No national study has investigated whether immigrant workers are less likely than U.S.-workers to seek medical treatment after occupational injuries and whether the payment source differs between two groups. Methods Using the 2004–2009 Medical Expenditure Panel Survey (MEPS) data, we estimated the annual incidence rate of nonfatal occupational injuries per 100 workers. Logistic regression models were fitted to test whether injured immigrant workers were less likely than U.S.-born workers to seek professional medical treatment after occupational injuries. We also estimated the average mean medical expenditures per injured worker during the 2 year MEPS reference period using linear regression analysis, adjusting for gender, age, race, marital status, education, poverty level, and insurance. Types of service and sources of payment were compared between U.S.-born and immigrant workers. Results A total of 1,909 injured U.S.-born workers reported 2,176 occupational injury events and 508 injured immigrant workers reported 560 occupational injury events. The annual nonfatal incidence rate per 100 workers was 4.0% (95% CI: 3.8%-4.3%) for U.S.-born workers and 3.0% (95% CI: 2.6%-3.3%) for immigrant workers. Medical treatment was sought after 77.3% (95% CI: 75.1%-79.4%) of the occupational injuries suffered by U.S.-born workers and 75.6% (95% CI: 69.8%-80.7%) of the occupational injuries suffered by immigrant workers. The average medical expenditure per injured worker in the 2 year MEPS reference period was $2357 for the U.S.-born workers and $2,351 for immigrant workers (in 2009 U.S. dollars, P = 0.99). Workers’ compensation paid 57.0% (95% CI: 49.4%-63.6%) of the total expenditures for U.S.-born workers and 43.2% (95% CI: 33.0%-53.7%) for immigrant workers. U.S.-born workers paid 6.7% (95% CI: 5.5%-8.3%) and immigrant workers paid 7.1% (95% CI: 5.2%-9.6%) out-of-pocket. Conclusions Immigrant workers had a statistically significant lower incidence rate of nonfatal occupational injuries than U.S.-born workers. There was no significant difference in seeking medical treatment and in the mean expenditures per injured worker between the two groups. The proportion of total expenditures paid by workers’ compensation was smaller (marginally significant) for immigrant workers than for U.S.-born workers. PMID:22905938

Occupational injuries are the second leading cause of trauma admission in Qatar. Given the wide diversity of the country's migrant worker populations at risk, this study aimed to analyse and describe the epidemiology of these injuries based on the workers nationality residing in Qatar. A retrospective analysis of trauma registry data on occupational-related injuries was conducted. The analysis included all patients [aged ≥18 years] admitted to the Level I Hamad Trauma Center, from January 1, 2010 to December 31, 2013. Out of 6555 trauma admissions, 2015 (30.7%) patients had occupational injury. The admitted Case Fatality Rate (CFR) was 4.3 per 100 occupational injury related trauma admissions. Overall non-fatal occupational injury rate was 37.34 per 100,000 workers, whereas fatal injury rate was 1.58 per 100,000 workers. Most of the workers experiencing occupational injuries were from Nepal (28%), India (20%) and Bangladesh (9%). Fatal occupational injuries were predominately among Indians (20%), Nepalese (19%), and Filipinos/Bangladeshis (both 8%). Filipinos had the highest admitted CFR at 8.2 deaths per 100 trauma admissions with the next highest being Indians and Indonesians (4.2 per 100 trauma admissions). During the study period, the incidence of severe occupational injuries decreased despite a simultaneous increase in the worker population within Qatar. Almost one in four occupational injuries was a major trauma (ISS≥16). Nepalese and Indian workers represented 29% and 18% of all major trauma cases. Non-fatal occupational injuries appear to follow a pattern distinct from fatal ones. High-risk worker populations as defined by those with high admitted CFRs, experiencing the most severe or fatal injuries, must be the focus of targeted risk factor analysis and occupational safety interventions.

Workers in certain occupations may be at an increased risk of a violent-related death such as homicide or suicide. The purpose of this study is to describe rates of violent deaths among Georgia workers by occupation, including cases occurring at work and outside of the workplace, and identify leading circumstances surrounding suicides and homicides for the occupations most at risk. Data from the 2006-2009 Georgia Violent Death Reporting System were used. Occupational text fields were recoded into 23 major occupation categories based on the 2010 Standard Occupational Classification system. Crude rates and standardized mortality ratios for violent deaths (suicides and homicides) were calculated by occupation among Georgia workers aged ≥16 years. The leading circumstances precipitating violent deaths among the high-risk occupations were described. Analyses were conducted during 2012-2013 and 2015. A total of 4,616 Georgia resident workers were victims of a violent death during 2006-2009. Of these deaths, 2,888 (62.6%) were suicides and 1,728 (37.4%) were homicides. Farming, fishing, and forestry occupations had the highest rate of violent deaths at 80.5 per 100,000 workers followed by construction and extraction occupations at 65.5 per 100,000. The most common suicide circumstances among workers were having a current depressed mood, a current mental health problem, and an intimate partner problem. Use of the Violent Death Reporting System provides a unique opportunity to explore violent deaths among workers. This analysis shows the need to ensure that workers have access to workplace and community-based suicide and violence prevention services. Copyright © 2016 American Journal of Preventive Medicine.

Objective: To investigate the association between 5-hydroxytryptamine 2A (5-HT2A) receptor gene polymorphisms and occupational stress in oilfield workers. Methods: Cluster sampling was used to select 826 oilfield workers from January to August, 2013. The SNaPshot single nucleotide polymorphism (SNP) genotyping method was used to determine the genotypes of rs6313, rs1923884, and rs2070040 in 5-HT2A receptor gene, and the Occupational Stress Inventory-Revised Edition was used to analyze occupational stress in these workers. Results: There were no significant differences in occupational stress between groups with different individual characteristics ( P >0.05 ) . As for the comparison of occupational stress scores between workers with different genotypes of each SNP of 5-HT2A receptor gene, the workers with CC and CT genotypes of rs6313 had significantly higher role boundary scores than those with TT genotype ( P <0.05) , and the workers with CC genotype had a significantly higher vocational stress score than those with CT genotype ( P <0.05) ; the workers with CT genotype of rs1923884 had a significantly higher occupational role score than those with CC genotype ( P <0.05) and a significantly higher coping resources score than those with CC and TT genotypes ( P <0.05) ; the workers with AG genotype of rs2070040 had a significantly higher vocational stress score than those with AA genotype ( P <0.05) . The ordinal multinomial logistic regression analysis showed that workers with CT genotype of rs1923884 were susceptible to occupational stress ( OR =1.56, 95% CI 1.10~2.20) . Conclusion: CT genotype of rs1923884 in 5-HT2A receptor gene may be associated with the susceptibility to occupational stress in oilfield workers.

Stuck at the bottom rung: occupational characteristics of workers with disabilities.

PubMed

Kaye, H Stephen

2009-06-01

The proportion of workers reporting disabilities varies tremendously across occupations. Although differences in the occupational distributions may partly explain the large disparities in earnings and job security between workers with and without disabilities, little is known about the reasons that workers with disabilities are underrepresented in certain occupations and overrepresented in others. Using a large, national survey of the US population combined with official data on the skill and experience requirements and occupational risks of 269 occupations, a multilevel regression analysis was performed to identify occupational and individual factors that influence the representation of workers with disabilities across occupations. Models of overall, sensory, mobility, and cognitive disability were constructed for working-age labor force participants, as were models of overall disability for younger, in-between, and older workers. At the occupational level, reported disability is negatively associated with occupational requirements for information and communication skills and with the amount of prior work experience that is required, after controlling for individual factors such as age and educational attainment. Little relationship is found between disability status and a set of occupational risk factors. These findings generally hold true across disability types and age groups. Even after taking into account their lower average educational attainment, workers with disabilities appear to be disproportionately relegated to entry-level occupations that do not emphasize the better-remunerated job skills. Underemployment results in lower wages and less job security and stability. Possible reasons include employer discrimination, low expectations, deficits in relevant skills or experience, and work disincentives.

2016-10-01

The present review focused on the levels and toxicological status of heavy metals especially chromium (Cr) in the exposed workers from different occupational settings around the globe and in Pakistan. It was found that exposed workers from leather tanning and metal plating units showed elevated levels of Cr than the workers from other occupational settings. Cr and other heavy metals level in biological matrices of the exposed workers in different occupational settings revealed that developing countries are severely contaminated. Occupational settings from the Sialkot district, Pakistan exhibited elevated level of Cr in biological entities of the exposed workers. Review suggested that higher level of Cr exposure to the workers enhance the oxidative stress (reactive oxygen species (ROS) and hydroxyl (OH) radical generation) which may cause; cellular and molecular damage such as genotoxicity and chromosomal aberration formations, and carcinogenic effects. This review will help to understand the Cr contamination mechanisms and associated health implications in different occupational settings around the globe in general and particularly to Pakistan. This study will also assist occupational health and safety management authorities to devise or change the Cr recommended exposure limits (REL) for different occupational settings.

Occupational Trajectories and Immigrant Worker Health

PubMed Central

Crollard, Allison; de Castro, A. B.; Tsai, Jenny Hsin-Chun

2013-01-01

During their initial years in the receiving country, many immigrants experience occupational downgrading. Downgrading is a loss of occupational status between one’s last job in the home country and first job in the receiving country, often resulting in overeducation or overqualification. Although the extent and determinants of such occupational trajectories have been characterized, the connection to immigrant worker health has not been widely examined. However, an emerging body of knowledge indicates that negative health outcomes are associated with overeducation and overqualification in general worker populations, suggesting similar experiences by immigrant workers. This article provides an overview of the magnitude and conceptualization of occupational downgrading, overeducation, and overqualification and discusses implications for immigrant worker health. Occupational health professionals should spearhead research efforts on occupational downgrading, raise public awareness about the issue, and serve as advocates for immigrant workers’ rights.

Workers with disabilities have a higher risk of nonfatal occupational injuries than workers without disabilities. The characteristics of these injuries are not well described. Using 1997-2011 National Health Interview Survey (NHIS) data, we compared the nonfatal occupational injuries sustained by U.S. workers with and without disabilities. Overexertion or strenuous movements and falls accounted for 56.7% of all occupational injuries in workers with disabilities, compared with 45.6% in workers without a disability. Workers with disabilities were more frequently injured in the lower extremity (32.3% vs. 26.6%) or torso (22.9% vs. 16.9%). Workers with disabilities sustained more unspecified injuries (13.5% vs. 7.9%) and fewer open wound injuries (15.7% vs. 24.2%) than their counterparts without a disability. U.S. workers with disabilities had a higher rate of occupational injuries and these injuries tended to be more severe and were more likely to be caused by overexertion/ strenuous movement or falls. © 2015 Wiley Periodicals, Inc.

Graham, John R; Shier, Micheal L; Nicholas, David

2016-06-01

Workplace expectations reflect an important consideration in employee experience. A higher prevalence of workplace congruence between worker and employer expectations has been associated with higher levels of productivity and overall workplace satisfaction across multiple occupational groups. Little research has investigated the relationship between workplace congruence and occupational health outcomes among social service workers. This study sought to better understand the extent to which occupational congruence contributes to occupational outcomes by surveying unionised social service workers ( n = 674) employed with the Government of Alberta, Canada. Multiple regression analysis shows that greater congruence between workplace and worker expectations around workloads, workplace values and the quality of the work environment significantly: (i) decreases symptoms related to distress and secondary traumatic stress; (ii) decreases intentions to leave; and (iii) increases overall life satisfaction. The findings provide some evidence of areas within the workplace of large government run social welfare programmes that can be better aligned to worker expectations to improve occupational outcomes among social service workers.

Workplace expectations reflect an important consideration in employee experience. A higher prevalence of workplace congruence between worker and employer expectations has been associated with higher levels of productivity and overall workplace satisfaction across multiple occupational groups. Little research has investigated the relationship between workplace congruence and occupational health outcomes among social service workers. This study sought to better understand the extent to which occupational congruence contributes to occupational outcomes by surveying unionised social service workers (n = 674) employed with the Government of Alberta, Canada. Multiple regression analysis shows that greater congruence between workplace and worker expectations around workloads, workplace values and the quality of the work environment significantly: (i) decreases symptoms related to distress and secondary traumatic stress; (ii) decreases intentions to leave; and (iii) increases overall life satisfaction.

Background This study provides a national profile of occupational fatalities among truck drivers and driver-sales workers. Methods Data from the 2003–2008 Census of Fatal Occupational Injuries were used. Cases were extracted specifically for occupational subcategories included in the Driver/Sales Workers and Truck Drivers occupational category: Driver/Sales Workers, Heavy and Tractor-Trailer Truck Drivers, and Light Truck or Delivery Services Drivers. Results In 2003–2008, the group Driver/Sales Workers and Truck Drivers had 5,568 occupational fatalities, representing 17% of all occupational fatalities in the United States. The majority of these fatalities were in the subgroup Heavy and Tractor-Trailer Truck Drivers (85%) and due to transportation incidents (80%). Older and male drivers had higher fatality rates than their counterparts. Conclusions Findings suggest a need for targeted interventions to reduce highway fatalities among heavy truck drivers. Better employment data are needed to separate the three occupational subcategories by worker characteristic and employment history for use in research and prevention efforts. PMID:24811905

This review considers the state of occupational injury surveillance and prevention among migrant workers in China and suggests areas of focus for future research on the topic. Bibliographic databases were searched for qualitative and quantitative studies on surveillance of and interventions to prevent occupational injury among migrant workers in mainland China. Additional abstracts were identified from the citations of relevant articles from the database search. Studies fitting the inclusion criteria were evaluated, and findings were extracted and summarised. The search uncovered 726 studies in the English-language databases searched, and 3109 in the Chinese database. This article analyses a total of 19 research articles that fit the inclusion criteria with qualitative or quantitative data on occupational injury surveillance and prevention of migrant workers in China. Despite evidence of the vulnerability of migrant workers in the workplace, there is little systematic surveillance of occupational injury and few evaluated interventions. Migrant workers account for a disproportionate burden of occupational injury morbidity and mortality in China. However, data are inconsistent and inadequate to detail injury incidence or to evaluate interventions. The following are suggestions to decrease injury incidence among migrants: strengthen the national system of occupational injury surveillance; focus surveillance and interventions on high-risk occupations employing migrants such as construction, manufacturing and small mining operations; improve occupational safety training and access to appropriate safety equipment; evaluate recent changes in occupational health and safety and evaluate outcome of multi-party interventions to reduce occupational injury among migrant workers.

Objective: To investigate occupational stress in migrant workers in an electronics manufacturing service enterprise and the association between occupational stress and early health effects, such as job burnout, depressive tendency, and insomnia. Methods: In August 2015, stratified random cluster sampling was used to select 1 097 migrant workers in an electronics manufacturing service enterprise. The Job Demand-Autonomy Questionnaire and effort-reward imbalance questionnaire were used to investigate occupational stress with the types of high workload and effort-reward imbalance, and Burnout Inventory, depression scale, and self-management sleep questionnaire were used to investigate the early health effects of occupational stress. Results: In these migrant workers, the detection rates of occupational stress with the types of high workload and effort-reward imbalance were 69.8%(766/1 097) and 11.9%(131/1 097). The multivariate logistic regression analysis showed that the workers who had occupational stress with the types of high workload and effort-reward imbalance had significantly higher risks of job burnout and depressive tendencies than those who did not have these two types of occupational stress ( P <0.01). The workers who had occupational stress with the type of effort-reward imbalance had a significantly higher ability to predict the risks of job burnout and depressive tendencies than those who had occupational stress with the type of high workload ( P <0.01) , as well as a significantly higher risk of insomnia than those who did not have this type of occupational stress ( P <0.01). Conclusion: Occupational stress is the major influencing factor for early health effects, such as job burnout, depressive tendency, and insomnia, in the migrant workers in this electronics manufacturing service enterprise. The workers who have occupational stress with the type of effort-reward imbalance have higher risks of job burnout and depressive tendencies than those who have occupational stress with the type of high workload.

Five workers from a plant manufacturing concrete wall panels and beams were referred to our department because of suspected occupational dermatitis. When patch tested, 3 workers reacted to potassium dichromate. Four workers reacted to ethylenediamine dihydrochloride, without any obvious exposure. Owing to the high proportion of workers with recent-onset skin disease, an investigation of all workers at the plant was initiated. To investigate the prevalence of occupational dermatitis and contact allergy in the workers at the plant. All 24 workers at the plant underwent a clinical investigation and were patch tested. Four cases of allergic occupational contact dermatitis and 3 cases of irritant occupational contact dermatitis were diagnosed. Contact allergy to potassium dichromate was found in 4 workers. All 4 also reacted to ethylenediamine dihydrochloride and/or amines that were present as additives in the cement. Chromate contact allergy can still be found in concrete workers, despite the legislation regulating the amount of hexavalent chromium (chromate) in cement. Occupational contact allergy to amines can be found in workers exposed to cement and concrete, so amines should be tested in these workers. © 2016 John Wiley & Sons A/S.

In the absence of systematic occupational disease surveillance, other data collected by governmental agencies or industry is useful in the identification of occupational diseases and their control. We examined data on occupational diseases reported by non-governmental employees to the national workers' social security organization in Malaysia, 2002-2006. The overall incidence rate of occupational disease was 2.8 per 100,000 workers. There was an increase in the annual number and rates of occupational disease over time. The most frequently reported conditions were hearing impairment (32%) and musculoskeletal disorders (28%). Workers in the non-metallic manufacturing industry had the highest average incidence rate of hearing impairment (12.7 per 100,000 workers) and musculoskeletal disorders (3.5 per 100,000 workers), compared to all other industries. Preventive measures should focus on safety education, engineering control and workplace ergonomics. Enforcing workplace standards and incorporating an ongoing surveillance system will facilitate the control and reduction of occupational disease.

Occupational Health in Community Health Centers: Practitioner Challenges and Recommendations.

Simmons, Juliana M; Liebman, Amy K; Sokas, Rosemary K

2018-05-01

Primary care clinicians may be the only source of occupational healthcare for many low-wage, high-risk workers who experience disproportionate occupational hazards. The authors explored barriers to providing occupational healthcare and recommendations for overcoming these challenges. The team conducted six focus groups and eleven key-informant interviews in two community health centers and among clinicians, community health workers, and other personnel from similar settings. Clinicians reported not utilizing occupational information during clinical encounters and identified competing priorities, limited appointment time, and lack of training as key barriers. They cited workers' compensation as a source of confusion and frustration. However, most participants recognized occupation as an important social determinant of health and expressed interest in additional training and resources. Participants agreed that referral mechanisms for occupational medicine specialists and worker centers and changes in quality performance measures and electronic health records would be useful and that workers' compensation and immigration policies need reform.

To present the costs of fatal and non-fatal days-away-from-work injuries in 50 construction occupations. Our results also provide indirect evidence on the cost exposure of alternative construction workers such as independent contractors, on-call or day labor, contract workers, and temporary workers. We combine data from the Bureau of Labor Statistics on average annual incidence from 2000 to 2002 with updated per-case costs from an existing cost model for occupational injuries. The Current Population Survey provides data on the percentage of alternative construction workers. Construction laborers and carpenters were the two costliest occupations, with 40% of the industry's injury costs. The 10 costliest construction occupations also have a high percentage of alternative workers. The construction industry has both a high rate of alternative employment and high costs of work injury. Alternative workers, often lacking workers' compensation, are especially exposed to injury costs.

Abstract The present study aims to investigate psychological stress and its determinants in Xinjiang field oil workers. Specifically, we aim to elucidate the mechanisms underlying psychological stress by comprehensively and quantitatively evaluating the processes involved in psychological stress, the factors which influence it, and their relationship. The participants were 1200 field oil workers in Xinjiang who had been in service for at least 1 year. A structural equation model based on data from the symptom checklist, social support research scale, personality questionnaire, occupational burnout questionnaire, and occupational stress questionnaire was constructed to investigate the social (environmental) factors that influence physiological stress and the interplay among these factors. The positive incidence of psychological stress in the field oil workers in Xinjiang was 12.54%. The structural equation model indicated that the main factors that influenced psychological stress in these workers included social support (0.077), occupational role (0.165), personal strain response (0.139), personality (0.189), and occupational burnout (0.380). Among these factors, occupational role, personality, and occupational burnout had a relatively strong predictive power for psychological stress reactions. The cortisol level in workers with positive psychological stress was significantly higher than that in workers with negative psychological stress. Occupational stress, personality, and occupational burnout exert an impact on psychological stress in field oil workers. Therefore, interventions to address these factors should be taken to reduce the incidence of psychological stress. PMID:29642166

To investigate the current status of occupational health and related countermeasures in Guangzhou, China. Related data were collected from occupational poisoning accident investigation, diagnosis and identification of occupational diseases, and the occupational disease hazard reporting system, and the statistical data of occupational health in Guangzhou were analyzed retrospectively. The number of enterprises reporting for occupational disease hazards in Guangzhou was 20 890, and the total number of workers was 1 457 583. The number of workers exposed to occupational hazards was 284 233, and the cumulative number of workers with occupational diseases was 1 502. There were many risk factors for occupational diseases in enterprises, and there were a large number of workers with occupational diseases, as well as newly diagnosed cases. From 2001 to 2014, the total number of cases of occupational diseases was 958. The situation for the prevention and control of occupational diseases is grim in Guangzhou. Occupational health supervision and law enforcement should be enhanced, the three-level supervision system should be established and perfected, and the occupational health supervision system with a combination of "prevention, treatment, and protection" should be established and promoted, so as to gradually establish a technical service support system for occupational health.

The objective of this work was to identify the high-risk occupations in Iran and to re-inspect occupations that were related to bladder cancer. In the study, 300 patients suffering from bladder cancer and 500 control individuals were interviewed. Demographic information, occupational history, and history of exposure to chemical compounds such as aromatic amines for each participant were collected. ORs and 95% CIs were calculated using unconditional logistic regression for each occupation. There was a significantly increased risk of bladder cancer among truck and bus drivers (OR = 11.3), skilled agricultural, forestry and fishery workers (OR = 6.0), metal industry workers (OR = 6.0), domestic housekeepers (OR = 5.9), and construction workers (OR = 3.8). The study showed a strong correlation between truck and bus drivers, skilled agricultural, forestry and fishery workers, metal industry workers, domestic housekeepers, as well as construction workers and the increased risk of bladder cancer in these occupations.

Purpose This study aims to investigate the occupational hazards among the abattoir workers associated with noncompliance to the meat processing and waste disposal laws in Terengganu State, Malaysia. Occupational hazards are the major source of morbidity and mortality among the animal workers due to exposure to many hazardous situations in their daily practices. Occupational infections mostly contracted by abattoir workers could be caused by iatrogenic or transmissible agents, including viruses, bacteria, fungi, and parasites and the toxins produced by these organisms. Materials and methods The methodology was based on a cross-sectional survey using cluster sampling technique in the four districts of Terengganu State, Malaysia. One hundred and twenty-one abattoir workers from five abattoirs were assessed using a validated structured questionnaire and an observation checklist. Results The mean and standard deviation of occupational hazards scores of the workers were 2.32 (2.721). Physical, chemical, biological, psychosocial, musculoskeletal, and ergonomics hazards were the major findings of this study. However, the highest prevalence of occupational hazards identified among the workers was injury by sharp equipment such as a knife (20.0%), noise exposure (17.0%), and due to offensive odor within the abattoir premises (12.0%). Conclusion The major occupational hazards encountered by the workers in the study area were physical, chemical, biological, psychosocial, musculoskeletal, and ergonomics hazards. To ensure proper control of occupational health hazards among the abattoir workers, standard design and good environmental hygiene must be taken into consideration all the time. Exposure control plan, which includes risk identification, risk characterization, assessment of workers at risk, risk control, workers’ education/training, and implementation of safe work procedures, should be implemented by the government and all the existing laws governing the abattoir operation in the country should be enforced.

2016-01-01

Objectives Qualitative studies have highlighted the possibility of job loss following occupational injuries for some workers, but prospective investigations are scant. We used a sample of nursing home workers from the Work, Family, and Health Network to prospectively investigate association between occupational injuries and job loss. Methods We merged data on 1331 workers assessed four times over an 18-month period with administrative data that include job loss from employers and publicly-available data on their workplaces. Workers self-reported occupational injuries in surveys. Multivariable logistic regression models estimated risk ratios for the impact of occupational injuries on overall job loss, whereas multinomial models were used to estimate odds ratio of voluntary and involuntary job loss. Use of marginal structural models allowed for adjustments of multilevel list of confounders that may be time-varying and/or on the causal pathway. Results By 12 months, 30.3% of workers experienced occupational injury, whereas 24.2% experienced job loss by 18 months. Comparing workers who reported occupational injuries to those reporting no injuries, risk ratio of overall job loss within subsequent 6 months was 1.31 (95% CI=0.93–1.86). Comparing the same groups, injured workers had higher odds of experiencing involuntary job loss (OR:2.19; 95% CI:1.27–3.77). Also, compared to uninjured workers, those injured more than once had higher odds of voluntary job loss (OR:1.95; 95% CI:1.03–3.67), while those injured once had higher odds of involuntary job loss (OR:2.19; 95% CI:1.18–4.05). Conclusions Despite regulatory protections, occupational injuries were associated with increased risk of voluntary and involuntary job loss for nursing home workers. PMID:26786757

Silicosis is a slowly progressive chronic occupational lung disease, developed after a prolong period of exposure to high concentration of silica dust. In this longitudinal study, we enrolled old and new silicosis patients (n=19; 8 jewellery polishers, 11 from other occupations) seen at our Pulmonary Medicine Department from June 2009 to December 2012 to document the course of illness as per their occupational exposure. Six of the eight jewellery polishing workers had developed silicosis within five years of exposure, while six of the 11 other workers with other occupational exposure had developed silicosis after exposure of 10 years or more. Mean duration of exposure was significantly less among jewellery polishing workers compared to other workers (3.4 +/- 1.7 versus 9.3 +/- 4.1; p=0.001). Mean duration of illness (months) (14.9 +/- 5.8 versus 28.5 +/- 16.5; p=0.040) were significantly less among the jewellery polishing workers compared to other workers. At the end of the study period, all eight jewellery polishing workers with silicosis had died while four of the 11 patients with other occupational exposure had died. Silicosis among jewellery polishing workers was found to be more severe and progressive compared to silicosis due to other occupational exposures, in our study.

A longitudinal and comparative study of psychological distress among professional workers in regulated occupations in Canada.

Cadieux, Nathalie; Marchand, Alain

Although several studies are concerned by the phenomenon of psychological distress at work, few studies have looked at the prevalence of psychological distress among professional workers in the regulated occupations and compare this prevalence with other occupations. This study propose to define regulated occupations by laying out the theoretical boundaries that apply to the practice of these occupations and try to understand how regulated occupations contributed to the experience of psychological distress in the Canadian workforce over time. Multilevel logistical regression analyses on longitudinal data were performed to compare the odds of experiencing psychological distress over time among professional workers in regulated occupations (n=276) and among other professional workers, classified into 6 categories (n=6731), over a 12-year period. The results show that proportion of distress in the workforce decreases for all occupations between Cycle 1 and Cycle 7 of the NPHS, but this decrease is not linear over time. The results show also that regulated occupations present a lower probability of psychological distress only when compared with white-collar workers. These results suggest that occupation contributes little toward understanding the prevalence of psychological distress in the Canadian workforce. Further research needs are also discussed.

Serial peak expiratory flow (PEF) records have been recommended as a first-line investigation in workers suspected as having occupational asthma (OA). To determine which PEF variability index best differentiates workers with OA from non-occupational asthmatics and unaffected irritant-exposed workers. PEF was measured at least four times daily for at least 3 weeks in three groups of subjects: (i) forty healthy grain-exposed farmers and dockers, (ii) forty-two consecutive workers with independently confirmed OA and (iii) forty-eight non-occupational asthmatics. Indices of PEF variability were compared between groups. The difference in mean PEF between rest and work periods best separated the occupational asthmatic workers from the others. The upper 95% confidence limit of this index for grain-exposed workers was 2.8% of predicted PEF (16 l/min) and 3.3% (15 l/min) for non-occupational asthmatics. Sensitivity for diagnosing OA using this index was 70%. An increase in diurnal variation on workdays of >7% had a sensitivity of only 27% for the diagnosis of OA. The difference between maximum PEF on workdays and minimum PEF on rest days had a sensitivity of <10% against non-occupational asthmatic controls. Difference in mean PEF between workdays and rest days is the best simple index for differentiating subjects with OA from those with non-OA or irritant-exposed healthy subjects. Differences >16 l/min are unlikely to be due to significant irritant exposure in healthy workers.

This report provides technical data regarding the reuse of excess foundry sand. The report addresses three topics: a statistically sound evaluation of the characterization of foundry sand, a laboratory investigation to qualify excess foundry sand as a major component in controlled low-strength material (CLSM), and the identification of the best methods for using foundry sand as a replacement for natural aggregates for construction purposes, specifically in asphalt paving materials. The survival analysis statistical technique was used to characterize foundry sand over a full spectrum of general chemical parameters, metallic elements, and organic compounds regarding bulk analysis and leachate characterization. Notmore » limited to characterization and environmental impact, foundry sand was evaluated by factor analyses, which contributes to proper selection of factor and maximization of the reuse marketplace for foundry sand. Regarding the integration of foundry sand into CLSM, excavatable CLSM and structural CLSM containing different types of excess foundry sands were investigated through laboratory experiments. Foundry sand was approved to constitute a major component in CLSM. Regarding the integration of foundry sand into asphalt paving materials, the optimum asphalt content was determined for each mixture, as well as the bulk density, maximum density, asphalt absorption, and air voids at Nini, Ndes, and Nmax. It was found that foundry sands can be used as an aggregate in hot-mix asphalt production, but each sand should be evaluated individually. Foundry sands tend to lower the strength of mixtures and also may make them more susceptible to moisture damage. Finally, traditional anti-stripping additives may decrease the moisture sensitivity of a mixture containing foundry sand, but not to the level allowed by most highway agencies.« less

Occupational segregation and earnings inequality: Rural migrants and local workers in urban China.

PubMed

Zhang, Zhuoni; Wu, Xiaogang

2017-01-01

This article examines the central role of occupation as the "reward packages" in creating earnings disparities between rural migrants and local workers in urban China's labor markets. Analyses of data from the population mini-census of China in 2005 show that, rural migrants' earnings disadvantages are largely attributable to occupational segregation (between-occupation variation) by workers' household registration status (hukou) rather than unequal pay within the same occupations, but surprisingly they enjoy a slight earnings advantage in lower-status occupations (within-occupation variation). Even after controlling for education and other characteristics, occupational segregation by hukou status continues to exist. The occupational segregation is the most severe in government agencies/state institutions and the least severe in the private sector, leading to earnings disparities between rural migrants and urban local workers in different work unit sectors. Our findings shed new light on how government discriminatory policies could affect occupational segregation and thereby create inequality among social groups in urban China.

To understand the status of occupational burnout of colliery migrant workers and its influencing factors. The occupational burnout of 1161 colliery migrant workers in Jinsha County, Guizhou Province was measured with MBI-GS and the self-made questionnaire. All dimensions of MBI-GS Cronbach's α coefficient was in the range of 0.86-0.88, all 15 items of MBI-GS were subjected to factor analysis, and three latent factors were identified, which explained 68.86% of the total variance and consisted with the theory model. The score of occupational burnout of each dimension, differences in different individual characteristics (physical examination, sleep, et al) were statistically significant (P <0.05). The influence factors of occupational burnout of colliery migrant workers were physical examination, chronic disease, smoking, physical exercise, sleep, initial work in coal mine, production post and labor intensity. MBI-GS can be used to study the occupational burnout of colliery migrant workers. Different individual characteristics effect the occurrence of occupational burnout.

Occupational injuries have considerable impact on workers' lives. However, data regarding workers' health-related quality of life (HRQOL) at several years after the injury are lacking. This study assessed workers' HRQOL at 6 years after occupational injury and determined related factors in each HRQOL domain. Workers who sustained an occupational injury in 2009 and who responded to a previous survey at 3 or 12 months after their injury were followed up in 2015. A total of 1715 participants were candidates for this study. The Taiwanese version of the World Health Organization Quality of Life scale-abbreviated version (WHOQOL-BREF) was used to assess their HRQOL. Multiple linear regression analysis identified predictive factors for HRQOL at 6 years after occupational injury. A total of 563 workers completed the questionnaire (response rate, 32.8%). Adverse life events and additional severe occupational injuries that occurred within the follow-up period, and decreased salary after the injury were significant factors for low scores in all domains of the WHOQOL-BREF. In addition, unmarried participants had low scores in the social relationship domain. Workers with family members requiring care scored low in the physical and environment domains. Workers whose injuries had major effects on their physical appearance had low scores in the physical and psychological domains. Workers with unstable employment had low scores in physical, psychological, and environment domains. At 6 years after occupational injury, workers' HRQOL was poor among those whose salaries decreased after the injury, after adjustment for other factors.

Studies indicate that persons employed in various retail occupations such as convenience stores and restaurants experience an increased risk for being a victim of an occupational homicide. A large proportion of workers aged 19 and under are employed in these types of occupations. The purpose of this study was to determine if the workers from this age group employed in retail trades have a significantly greater risk for being a victim of a homicide. Data from the Bureau of Labor Statistics' Census of Fatal Occupational Injuries were analyzed in this study. The cases included in this study were victims of an occupational homicide that occurred during the period of 1992 to 1996. Proportionate mortality ratios were used to identify the industries in which workers aged 19 and under were experiencing significantly higher proportion of fatalities. Relative risks were calculated to determine if, based on the number of person-years of exposure, workers aged 19 and under in retail trades were experiencing a significantly greater relative risk for being a victim of an occupational homicide. Results indicate that workers aged 19 and under experience a significantly greater proportion of fatalities due to violence in the retail trade. Workers 19 years and under employed in retail trade occupations do experience a significantly greater proportion of fatalities than their counterparts in other industries. Prevention strategies presented include providing employee training and implementing various security measures.

The aim of this study was to identify determinants of occupational sunburn in agricultural workers and assess their occupational and recreational sun protection habits. Specific surveys of agricultural workers in Switzerland and France were conducted (N = 1538). Multivariate logistic regressions identified occupational sunburn determinants. Occupational and recreational sun protection habits were estimated and correlated. One-year occupational and recreational sunburn prevalences were 19.8% and 11.5%, respectively. Occupational sunburn increased with having a recent recreational sunburn, highly sensitive skin, young age, high perceived skin cancer risk, using sunscreen, and not wearing a hat. Correlation between protection habits during work and leisure was substantial (rs 0.5 to 0.7). Skin health knowledge was high and pro-tanning attitude moderate. Potentially modifiable sunburn determinants and suboptimal recreational and occupational sun protection practices were identified in agricultural workers. Refining and tailoring sun protection messages targeting the agricultural sector are needed.

In industrializing countries, occupational safety and health have been affected by globalization. However, a lack of reliable data prevents evaluation of this situation. Therefore, we examined industrial distributions and risks of severe occupational injuries among workers in Thailand, which is one of the few industrializing countries that compiles nationwide data. Data on workers who made claims for occupational injuries from 2007 to 2009 were extracted from the Workmen's Compensation Fund records in Thailand. Among 501,334 claimants, we evaluated the industrial distributions of severe occupational injuries (i.e., permanent disability and death). We then examined the associations between industry and those injuries, using proportionate ratios (PRs) between each industrial category and the overall distribution of occupational injuries. The number of workers in manufacturing making claims for severe occupational injuries was the largest among all industrial categories (319,114/501,334 injuries), although the total number of occupational injuries recently declined. Additionally, workers in manufacturing experienced severe occupational injuries more often compared with the overall distribution of occupational injuries. The PRs (95% confidence interval) for manufacturing were 1.17 (1.14-1.20) in men and 1.33 (1.27-1.38) in women. After adjusting for individual characteristics, the results did not substantially change. Manufacturing seems to have the largest burden of occupational injuries in industrializing countries like Thailand.

Occupational injuries constitute a global health challenge, yet they receive comparatively modest scientific attention. Pattern of occupational injuries and its safety precautions among wagon repair workers is an important health issue, especially in developing countries like India. To assess the pattern of occupational injuries and utilization of safety measures among railway wagon repair workshop workers in Jhansi (U.P.). Railway wagon repair workshop urban area, Jhansi (U.P). Occupation-based cross-sectional study. A cross-sectional study was conducted among 309 workers of railway workshop in Jhansi (U.P.) who were all injured during the study period of 1 year from July 2015 to June 2016. Baseline characteristics, pattern of occupational injuries, safety measures, and their availability to and utilization by the participants were assessed using a pretested structured questionnaire. Data obtained were collected and analyzed statistically by simple proportions and Chi-square test. The majority of studied workers aged between 38 and 47 years ( n = 93, 30.6%) followed by 28-37 years ( n = 79, 26%). Among the pattern of occupational injuries, laceration (28.7%) was most common followed by abrasion/scratch (21%). Safety shoes and hat were utilized 100% by all workers. Many of them had more than 5 years of experience ( n = 237, 78%). Age group, education level, and utilization of safety measures were significantly associated with pattern of occupational injuries in univariate analysis ( P < 0.05). Occupational injuries are high and utilization of safety measures is low among workers on railway wagon repair workshop, which highlights the importance of strengthening safety regulatory services toward this group of workers. Younger age group workers show a significant association with open wounds and surface wounds. As the education level of workers increases, the incidence of injuries decreases. Apart from shoes, hat, and gloves, regular utilization of other personal protective equipment was not seen.

Occupational hearing loss is an increasingly prevalent occupational condition worldwide, and has been reported to occur in a wide range of workplaces; however, its prevalence among workers from municipal solid waste landfills (MSWLs) remains less clear. This study aimed to investigate the occupational hearing loss among Chinese MSWL workers. A cross-sectional study of 247 workers from 4 Chinese MSWLs was conducted. Noise and total volatile organic compounds (TVOCs) levels at worksites were determined. We conducted hearing examinations to determine hearing thresholds. A worker was identified as having hearing loss if the mean threshold at 2000, 3000 and 4000 Hz in either ear was equal to or greater than 25 dB. Prevalence of occupational hearing loss was then evaluated. Using unconditional Logistic regression models, we estimated the odds ratios (ORs) of MSWL work associated with hearing loss. According to the job title for each worker, the study subjects were divided into 3 groups, including group 1 of 63 workers without MSWL occupational hazards exposure (control group), group 2 of 84 workers with a few or short-period MSWL occupational hazards exposure, and group 3 of 100 workers with continuous MSWL occupational hazards exposure. Both noise and TVOCs levels were significantly higher at worksites for group 3. Significantly poorer hearing thresholds at frequencies of 2000, 3000 and 4000 Hz were found in group 3, compared with that in group 1 and group 2. The overall prevalence rate of hearing loss was 23.5%, with the highest in group 3 (36.0%). The OR of MSWL work associated with hearing loss was 3.39 (95% confidence interval [CI]: 1.28-8.96). The results of this study suggest significantly higher prevalence of hearing loss among MSWL workers. Further studies are needed to explore possible exposure-response relationship between MSWL occupational hazards exposure and hearing loss.

To explore the effects of occupational stress on neurotransmitters in petroleum workers. 178 petroleum workers with the length of service ≥ 1 year were recruited to the subjects by the questionnaire of OSI-R. The levels of 5-hydroxy tryptamine (5-HT), norepinephrine (NE), neuropeptide Y (NPY) and substance P (SP) in serum were measured. The subjects were classified into 3 groups according to the scores of occupational stress. The levels of 5-HT NE and SP for over 15 working years were higher than those of less than 15 years (P < 0. 05). There were differences (P < 0. 05) on 5-HT, NE, NPY and SP in different occupational stress degree groups, multiple comparison showed high. occupational stress group was higher than those of low occupational stress group. Multivariate correlation analysis showed that the occupational stress and sleep quality component scores correlated positively with the 5-HT, NE and SP (P < 0. 05) and correlated inversely with NPY in petroleum workers (P < 0. 05). Occupational stress in petroleum workers is correlated with serum monoamine and neuropeptides neurotransmitters, and it may affect serum levels of monoamine and neuropeptides neurotransmitters.

Occupational dermatoses contribute to a significant portion of work-related diseases, especially in Asia, where a major portion of the workforce is in the unorganized sector. This review article is focussed on the frequency and pattern of occupational skin diseases reported across Asian countries and type of allergens implicated in different occupations. The literature was searched systematically using key words 'occupational dermatoses,' 'occupational skin disease' and name of each Asian country. Ninty five full-text articles were considered relevant and evaluated. Some of the dermatoses seen in industrial workers in Asian countries are similar to those in Western countries, including dermatoses due to chromate in construction and electroplating workers, epoxy resin, and chromate in painters, wood dust in workers in the furniture industry, azo dyes in textile workers and formaldehyde and chromates in those working in the leather and dyeing industries, dermatoses in domestic workers, chefs and health-care workers. Dermatoses in workers engaged in agriculture, beedi (tiny cigars) manufacture, agarbatti (incense sticks) production, fish processing, carpet weaving, sanitation and those working in coffee plantations and coal mines appear to be unique to Asian countries. Recognition of clinical patterns and geographic variations in occupational skin diseases will provide an impetus to further strengthen future research in these areas, as well as improving their management.

Objective: To understand the status of occupational health surveillance to workers exposed to toxic environment in a city, so as to provide scientific basis for strategy of occupational diseases prevention. Methods: In January 2017, collecting the data of on-the-job poisonous and harmful workers occupational health surveillance in the city from January 1, 2010 to December 31, 2016 in China Information System for Disease Control and Prevention, the trend of occupational health monitoring in the city was analyzed, and the differences between diverseeconomic types, enterprise scale, industry nature and hazard factors were analyzed and compared. Results: The occupational health examination rate showed an overall upward trend in workers exposed to dust in the city from 2010-2016 ( t =3.607, P <0.05) , and the detection rate of occupational contraindications was on the rise in workers exposed to chemical factors ( t =3.071, P <0.05). The detection rate of occupational contraindications and suspected occupational diseaseswere significant in different economic types, enterprise scale, industry nature and hazard factors ( P <0.05). The detection rate of occupational contraindications was the highest among the large enterprises (1.24%) , the manufacturing industry (0.84%) and the state-owned economy (1.49%). The detection rate of suspected occupational diseases (0.04%) and occupational contraindications (1.15%) were the highest in the physical factors. Conclusion: Occupational health monitoring in the city is not optimistic. It is necessary to focuson the occupational health care of manufacturing practitioners, raise the detection rate of suspected occupational diseases, and standard the occupational health check work to protect the occupational health.

The aim of this study was to examine the relationship between occupation and sleep duration, sleepiness, insufficient sleep, and insomnia in day and shift workers (including night work and watches). The study was population-based and cross-sectional, and relied on self-administered questionnaires. It was conducted as part of the 1997-1999 Hordaland Health Study in collaboration with the Norwegian National Health Screening Service. Aged 40-45 years, 7782 participants answered a sleep questionnaire, reporting their occupation and whether or not they were employed in shift work. Our study found differences in sleep duration during the working week between occupational groups; in both shift and day workers. Craft workers, plant operators, and drivers slept less than leaders, and non-personal and personal service workers. Within some occupations (leaders, personal service workers, and plant operators), shift workers slept less than day workers. The mean sleep duration of shift workers was 15 minutes shorter than that of day workers. Rise times, but not bedtimes, were earlier in craft-and construction workers, plant operators, and drivers than in leaders and non-personal and personal service workers, particularly day workers. When adjusted for shift work and working hours - compared to leaders - craft workers, plant operators, and drivers had an increased risk of daytime sleepiness (odds ratio 1.5, 1.8, and 1.8 respectively) and of falling asleep at work (odds ratio 1.6, 2.1 and 2.0 respectively). Shift workers had an increased risk of falling asleep at work and insomnia. Occupation has separate effects on sleep duration and sleep-related problems, independent of the effects of shift work.

In epidemiologic studies that rely on professional judgment to assess occupational exposures, the raters' accurate assessment is vital to detect associations. We examined the influence of the type of questionnaire, type of industry, and type of rater on the raters' ability to reliably and validly assess within-industry differences in exposure. Our aim was to identify areas where improvements in exposure assessment may be possible. Subjects from three foundries (n = 72) and three textile plants (n = 74) in Shanghai, China, completed an occupational history (OH) and an industry-specific questionnaire (IQ). Six total dust measurements were collected per subject and were used to calculate a subject-specific measurement mean, which was used as the gold standard. Six raters independently ranked the intensity of each subject's current job on an ordinal scale (1-4) based on the OH alone and on the OH and IQ together. Aggregate ratings were calculated for the group, for industrial hygienists, and for occupational physicians. We calculated intra-class correlation coefficients (ICCs) to evaluate the reliability of the raters. We calculated the correlation between the subject-specific measurement means and the ratings to evaluate the raters' validity. Analyses were stratified by industry, type of questionnaire, and type of rater. We also examined the agreement between the ratings by exposure category, where the subject-specific measurement means were categorized into two and four categories. The reliability and validity measures were higher for the aggregate ratings than for the ratings from the individual raters. The group's performance was maximized with three raters. Both the reliability and validity measures were higher for the foundry industry than for the textile industry. The ICCs were consistently lower in the OH/IQ round than in the OH round in both industries. In contrast, the correlations with the measurement means were higher in the OH/IQ round than in the OH round for the foundry industry (group rating, OH/IQ: Spearman rho = 0.77; OH: rho = 0.64). No pattern by questionnaire type was observed for the textile industry (group rating, Spearman rho = 0.50, both assessment rounds). For both industries, the agreement by exposure category was higher when the task was reduced to discriminating between two versus four exposure categories. Assessments based on professional judgment may reduce misclassification by using two or three raters, by using questionnaires that systematically collect task information, and by defining intensity categories that are distinguishable by the raters. However, few studies have the resources to use multiple raters and these additional efforts may not be adequate for obtaining valid subjective ratings. Thus, improving exposure assessment approaches for studies that rely on professional judgment remain an important research need.

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.

Shliapnikov, D M; Kostarev, V G

2014-01-01

The article deals with results of a priori and a posteriori evaluation of occupational risk for workers' health. Categories of a priori occupational risk for workers are estimated as high to very high (intolerable) risk. Findings are that work conditions in nonferrous metallurgy workshop result in upper respiratory tract diseases (medium degree of occupational conditionality). Increased prevalence of such diseases among the workers is connected with length of service. The authors revealed priority factors for occupationally conditioned diseases. A promising approach in occupational medicine is creation of methods to evaluate and forecast occupational risk, that enable to specify goal parameters for prophylactic measures. For example, modelling the risk of occupationally conditioned diseases via changes in exposure to occupational factor and length of service proved that decrease of chemical concentrations in air of workplace to maximally allowable ones lowers risk of respiratory diseases from 14 to 6 cases per year, for length of service of 5 years and population risk.

2012-05-01

Our aims were to investigate possible associations between hospitalisation for venous thromboembolism (VTE) and socioeconomic and occupational factors. A nationwide database was constructed by linking Swedish census data to the Hospital Discharge Register (1990-2007). Hospital diagnoses of VTE were based on the International Classification of Diseases. Standardised incidence ratios were calculated for different socioeconomic and occupational groups. A total of 43063 individuals aged >20 years were hospitalised for VTE. Individuals with >12 years of education were at lower risk for VTE. Blue-collar workers, farmers, and non-employed individuals had higher risks for VTE, and white collar workers and professionals lower risks. In males and/or females, risks for VTE were increased for assistant nurses; farmers; miners and quarry workers; mechanics, iron and metalware workers; wood workers; food manufacture workers; packers; loaders and warehouse workers; public safety and protection workers; cooks and stewards; home helpers; building caretakers; and cleaners. Decreased risks were observed for technical, chemical, physical, and biological workers; physicians; dentists; nurses; other health and medical workers; teachers, religious, juridical, and other social science-related workers; artistic workers; clerical workers; sale agents; and fishermen, whalers and sealers. High educational level and several occupations requiring high levels of education were protective against VTE, while the risks for VTE were increased for farmers, blue-collar workers and non-employed individuals. The mechanisms are unknown but it might involve persistent psychosocial stress related to low socioeconomic and occupational status. Copyright © 2011 Elsevier Ltd. All rights reserved.

To evaluate the associations of perception of safety atmosphere at workplace, occupational safety attitude and behaviors with occupational unintentional injury among manufacturing workers. A cross-sectional study was performed and a self-administered questionnaire was used to inquire socio-demographic characteristics, perceived safety atmosphere, occupational safety attitudes, occupational safety behaviors and occupational unintentional injuries among 10585 manufacturing workers selected from 46 enterprises in Guangdong. Structural equation modeling was applied to assess the relationship of the perception of safety atmosphere at workplace, occupational safety attitude, and occupational safety behaviors with occupational unintentional injury. Among 24 pathways supposed in structural equation model, 20 pathways (except for the attitude toward occupational safety, the attitude toward managers' support, the work posture and individual protection) were significantly related to the occupational unintentional injuries. The further analysis indicated that the perceived safety atmosphere might impact the occupational unintentional injuries by the attitude toward occupational safety and occupational safety behaviors. Workers' perception of safety atmosphere indirectly influenced on occupational unintentional injuries through occupational safety attitudes and occupational safety behaviors.

The analysis of the national and international literature reveals a prevalence of around 20% of work-related musculoskeletal disorders in construction workers over 40 years of age. The chronic-degenerative disease in the muscular-skeletal system is important not only for the number of reported cases, but also for the seriousness of the symptoms, which are one of the main causes of evaluations of limited work-suability and unfitness for work. The aim of this study is to improve the quality of the diagnosis of occupational musculoskeletal illnesses and to ensure that the occupational physicians identify such disease, as prescribed by the Italian legislation about safety and health in workplaces. The research involved 57 construction companies located in the Bergamo's province, which employ, in aggregate, 833 workers. A sample of 479 workers, 40, or more, years old (403 Italians and 76 foreigners) was analysed. It was found out that 152 workers had some musculoskeletal disorders but only for 5 of them an occupational disease was already reported. It was necessary to ask the occupational physician for further clinical investigation for 60 employees, which revealed 29 new musculoskeletal occupational diseases in 19 workers. At the end of the study a total of 34 musculoskeletal occupational diseases were diagnosed in 22 workers: it was 4, 6% of the total sample investigated (n. 479) and 14% of those who already had problems (no 152). The results confirm the under-reporting of occupational musculoskeletal diseases in construction workers. The active research is a useful tool for the purposes of verifying the level of health surveillance carried out by occupational physicians. In fact the study highlighted that physicians seem not to be inclined to require additional clinical investigations and not always report occupational diseases.

An updated version of a national surveillance system of traumatic occupational fatalities was used to explore adjusted and unadjusted trends in rates of fatal injury. Data from the national traumatic occupational fatalities surveillance system were combined with data on employment from the United States Bureau of Labor Statistics. Poisson regression was then used to examine trends in rates of occupational fatality injuries while controlling for demographic and workplace characteristics. Adjusted annual changes in rates of fatal injuries ranged from a decline of 6.2% for workers in technical and administrative support occupations--for example, health, science, and engineering technicians, pilots, computer programmers--to an increase of 1.6% in machine operators, assemblers, and inspectors. For industries, annual changes ranged from a decline of 5.3% for workers in public administration--for example, justice, public order, and safety workers--to an increase of 2.6% for workers in the wholesale trade. By comparison, the annual decline over all industries and occupations was 3.1%. In many industries and occupations, an effect modification of annual trends by the age of the worker was also found with the oldest workers experiencing either no decline or a significant increase in rates of fatal injuries. This general pattern of decline, adjusted for the effects of demographic characteristics of the worker population, is encouraging; however, increases in rates of fatal injuries found in particular industries and occupations, suggest appropriate targets for increased injury prevention efforts.

To address the hypotheses that electrical workers are exposed to higher magnetic fields and are at higher risk of leukemia than nonelectrical workers, we performed a registry-based case-control study among men aged 20-64 years with known occupation who were diagnosed with cancer in Los Angeles County between 1972 and 1990. Controls were men with cancers other than those of the central nervous system or leukemia. Magnetic field measurements on workers in each electrical occupation and in a random sample of occupations presumed to be nonelectrical were used to estimate magnetic field exposures for each occupation. Among men in electrical occupations, 121 leukemias were diagnosed. With the exception of electrical engineers, magnetic field exposures were higher among workers in electrical occupations than in nonelectrical occupations. A weakly positive trend in leukemia risk across average occupational magnetic field exposure was observed (odds ratio [OR] per 10 milligauss increase in average magnetic field = 1.2, 95% confidence interval [CI] 1.0-1.5). A slightly stronger association was observed for chronic myloid leukemia, although only 28 cases occurred among electrical workers (OR 10 milligauss increase = 1.6, 95% CI = 1.2-2.0). The results were not materially altered by adjustment for exposure to several agents known or suspected to cause leukemia. Although not conclusive, these results are consistent with findings from studies based on job title alone that electrical workers may be at slightly increased risk of leukemia.

Poisson regression was then used to examine trends in rates of occupational fatality injuries while controlling for demographic and workplace characteristics. RESULTS: Adjusted annual changes in rates of fatal injuries ranged from a decline of 6.2% for workers in technical and administrative support occupations--for example, health, science, and engineering technicians, pilots, computer programmers--to an increase of 1.6% in machine operators, assemblers, and inspectors. For industries, annual changes ranged from a decline of 5.3% for workers in public administration--for example, justice, public order, and safety workers--to an increase of 2.6% for workers in the wholesale trade. By comparison, the annual decline over all industries and occupations was 3.1%. In many industries and occupations, an effect modification of annual trends by the age of the worker was also found with the oldest workers experiencing either no decline or a significant increase in rates of fatal injuries. CONCLUSIONS: This general pattern of decline, adjusted for the effects of demographic characteristics of the worker population, is encouraging; however, increases in rates of fatal injuries found in particular industries and occupations, suggest appropriate targets for increased injury prevention efforts.   PMID:9816383

In the distribution service industry, sales people often experience multiple occupational stressors such as excessive emotional labor, workplace mistreatment, and job insecurity. The present study aimed to explore the associations of these stressors with depressive symptoms among women sales workers at a clothing shopping mall in Korea. A cross sectional study was conducted on 583 women who consist of clothing sales workers and manual workers using a structured questionnaire to assess demographic factors, occupational stressors, and depressive symptoms. Multiple regression analyses were performed to explore the association of these stressors with depressive symptoms. Scores for job stress subscales such as job demand, job control, and job insecurity were higher among sales workers than among manual workers ( p < 0.01). The multiple regression analysis revealed the association between occupation and depressive symptoms after controlling for age, educational level, cohabiting status, and occupational stressors (sβ = 0.08, p = 0.04). A significant interaction effect between occupation and social support was also observed in this model (sβ = -0.09, p = 0.02). The multiple regression analysis stratified by occupation showed that job demand, job insecurity, and workplace mistreatment were significantly associated with depressive symptoms in both occupations ( p < 0.05), although the strength of statistical associations were slightly different. We found negative associations of social support (sβ = -0.22, p < 0.01) and emotional effort (sβ = -0.17, p < 0.01) with depressive symptoms in another multiple regression model for sales workers. Emotional dissonance (sβ = 0.23, p < 0.01) showed positive association with depressive symptoms in this model. The result of this study indicated that reducing occupational stressors would be effective for women sales workers to prevent depressive symptoms. In particular, promoting social support could be the most effective way to promote women sales workers' mental health.

The aim of this study was to estimate prevalence of injury by occupation and industry and obesity's role. Self-reported injuries were collected annually for US workers during 2004 to 2013. Prevalence ratios (PRs) and 95% confidence intervals (CIs) were obtained from fitted logistic regression models. Overall weighted injury prevalence during the previous three months was 77 per 10,000 workers. Age-adjusted injury prevalence was greatest for Construction and Extraction workers (169.7/10,000) followed by Production (160.6) among occupations, while workers in the Construction industry sector (147.9) had the highest injury prevalence followed by the Agriculture/Forestry/Fishing/Mining/Utilities sector (122.1). Overweight and obese workers were 26% to 45% more likely to experience injuries than normal-weight workers. The prevalence of injury, highest for Construction workers, gradually increased as body mass index levels increased in most occupational and industry groups.

We describe the socio-demographic, occupational, and health characteristics of "green collar" workers, a vital and emerging workforce in energy-efficiency and sustainability. We linked data from the 2004 to 2012 National Health Interview Surveys (NHIS) and US Occupational Information Network (O*NET). Descriptive and logistic regression analyses were conducted using green collar worker status as the outcome (n = 143,346). Green collar workers are more likely than non-green workers to be men, age 25 to 64 years, obese, and with less than or equal to high school (HS) education. They are less likely to be racial/ethnic minorities and employed in small companies or government jobs. Green collar workers have a distinct socio-demographic and occupational profile, and this workforce deserves active surveillance to protect its workers' safety. The NHIS-O*NET linkage represents a valuable resource to further identify the unique exposures and characteristics of this occupational sector.

Blue-collar workers have a high risk of occupational contact dermatitis, but epidemiological studies are scarce. To investigate allergic contact dermatitis in blue-collar workers with dermatitis registered by the Danish Contact Dermatitis Group. A retrospective analysis of patch test data from 1471 blue-collar workers and 1471 matched controls tested between 2003 and 2012 was performed. A logistic regression was used to test for associations. The blue-collar workers often had occupational hand dermatitis (p < 0.001). Atopic dermatitis was less commonly observed among blue-collar workers (19.6%) than among controls (23.9%) (p = 0.005). Allergens with a statistically significant association with the occupational group of blue-collar workers were epoxy resins, methyldibromo glutaronitrile, 2-bromo-2-nitro-1,3-propanediol, potassium dichromate, and methylchloroisothiazolinone (MCI)/methylisothiazolinone (MI). The following occupations were additionally identified as risk factors for contact sensitization to MCI/MI and MI, epoxy resins, and potassium dichromate, respectively: painting, construction work, and tile setting/terrazzo work. Contact allergy is a major problem among blue-collar workers. The data indicate a healthy worker effect among blue-collar workers diagnosed with dermatitis, as blue-collar workers were diagnosed significantly less often with atopic dermatitis than were controls. © 2014 John Wiley & Sons A/S.

The Thai Health Promotion Foundation supported the Improvement of Quality of Life of Informal Workers project in Ban Luang District, Amphur Photaram, Ratchaburi Province. There were many informal workers in Ban Luang District. Sweet-crispy fish producers in Ban Luang were the largest group among the sweet-crispy fish producers in Thailand. This project was aimed at improving living and working conditions of informal workers, with a focus on the sweet-crispy fish group. Good practices of improved living and working conditions were used to help informal workers build safe, healthy and productive work environments. These informal workers often worked in substandard conditions and were exposed to various hazards in the working area. These hazards included risk of exposure to hot work environment, ergonomics-related injuries, chemical hazards, electrical hazards etc. Ergonomics problems were commonly in the sweet-crispy fish group. Unnatural postures such as prolonged sitting were performed dominantly. One hundred and fifty informal workers participated in this project. Occupational health volunteers were selected to encourage occupational health and safety in four groups of informal workers in 2009. The occupational health volunteers trained in 2008 were farmers, beauty salon workers and doll makers. The occupational health and safety knowledge is extended to a new informal worker group: sweet-crispy fish producer, in 2009. The occupational health and safety training for sweet-crispy fish group is conducted by occupational health volunteers. The occupational health volunteers increased their skills and knowledge assist in to make safe home and safe community through participatory oriented training. The improvement of living and working condition is conducted by using a modified WISH, Work Improvement for Safe Home, checklist. The plans of improvement were recorded. The informal workers showed improvement mostly on material handling and storage. The safe uses and safe storage of chemicals were introduced among farmers. The awareness of healthcare using personal protective equipments is increased in all groups especially in farmers. Safe home by local occupational health volunteer is proposed to be one effective measure for improvement of quality of life.

To explore the influence of occupational stress on mental health in off-shore oil production. A cross-sectional survey was conducted among 561 Chinese off-shore oil workers. The workers were invited to fill in a self-administered questionnaire exploring their socio-demographic characteristics, occupational stress levels, and 12-item general health questionnaire. A hierarchical multiple regression procedure was used to assess the effects of occupational stress on mental health. After controlling for age, educational level, marital status and years of off-shore work, poor mental health was found to have a significant positive association with seven of the nine identified sources of occupational stress. They were: conflict between job and family/social life, poor development of career and achievement at work, safety problems at work, management problems and poor relationship with others at work, poor physical environment of the work place, uncomfortable ergonomic factors at work, and poor organizational structure at work. All of these occupational stress sources together explained 19.9% of the total variance. The results confirmed that occupational stress was a major risk factor for poor mental health among Chinese off-shore oil workers. Reducing or eliminating occupational stressors at work would benefit workers' mental health.

Several epidemiological studies have suggested that certain paternal occupations may be associated with an increased prevalence of birth defects in offspring. Using data from the National Birth Defects Prevention Study, the authors investigated the association between paternal occupation and birth defects in a case-control study of cases comprising over 60 different types of birth defects (n=9998) and non-malformed controls (n=4066) with dates of delivery between 1997 and 2004. Using paternal occupational histories reported by mothers via telephone interview, jobs were systematically classified into 63 groups based on shared exposure profiles within occupation and industry. Data were analysed using bayesian logistic regression with a hierarchical prior for dependent shrinkage to stabilise estimation with sparse data. Several occupations were associated with an increased prevalence of various birth defect categories, including mathematical, physical and computer scientists; artists; photographers and photo processors; food service workers; landscapers and groundskeepers; hairdressers and cosmetologists; office and administrative support workers; sawmill workers; petroleum and gas workers; chemical workers; printers; material moving equipment operators; and motor vehicle operators. Findings from this study might be used to identify specific occupations worthy of further investigation and to generate hypotheses about chemical or physical exposures common to such occupations.

Occupationally acquired HIV: the vulnerability of health care workers under workers' compensation laws.

PubMed Central

Tereskerz, P M; Jagger, J

1997-01-01

Approximately 800,000 needlesticks and other sharp injuries from contaminated medical devices occur in health care settings each year, of which an estimated 16,000 are contaminated by human immunodeficiency virus (HIV). Health care workers who are occupationally infected by HIV are at risk of being left without workers' compensation coverage. In some states, the definition of an occupational disease is so restrictive that infected health care workers are unlikely to qualify for benefits. For those who are able to meet the definition, compensation is often inadequate. Recourse is also limited by statutory provisions that preclude health care workers from bringing civil suits against their employers. We recommend the amendment of legislation to provide more equitable remedies, including: (1) broadening the definition of occupational disease; (2) eliminating provisions that require a claimant to prove that (a) a specific occupational incident resulted in infection and (b) HIV is not an ordinary disease of life; (3) expanding the time for filing a claim; (4) assuring that lifetime benefits will be provided to the disabled health care worker; and (5) assuring that claims will remain confidential.

Hamajima, N

This paper aims to introduce a measure for use by physicians for stating the degree of probable causal relationship for "Karoshi", ie, a sudden death from cerebrovascular diseases or ischemic heart diseases under occupational stresses, as well as to give a brief description for legal procedures associated with worker's compensation and civil trial in Japan. It is a well-used measure in epidemiology, "attributable risk percent (AR%)", which can be applied to describe the extent of contribution to "Karoshi" of the excess occupational burdens the deceased worker was forced to bear. Although several standards such as average occupational burdens for the worker, average occupational burdens for an ordinary worker, burdens in a nonoccupational life, and a complete rest, might be considered for the AR% estimation, the average occupational burdens for an ordinary worker should normally be utilized as a standard for worker's compensation. The adoption of AR% could be helpful for courts to make a consistent judgement whether "Karoshi" cases are compensatable or not.

We assessed the characteristics of micro-enterprises (businesses with fewer than five workers) focusing on occupational safety and health (OSH) issues. We performed a secondary analysis of data from the Economically Active Population Supplementary Survey and the fourth Korean Working Conditions Survey of 2014. Relative to larger businesses, micro-enterprises employ more women, temporary workers, and older workers (>55 years). In addition, more workers in micro-enterprises held "elementary occupations" (unskilled or under-skilled) or "sales and service jobs." Key sectors of such employment included the sectors of "wholesale and retail trade" and "hotel and restaurants." Furthermore, lower skilled workers in such micro-enterprises more frequently reported exposure to ergonomic risk factors and subsequent musculoskeletal disorders, and they also experienced a much higher fatality rate due to occupational injuries. Our results indicate that Korean workers in micro-enterprises are more vulnerable to OSH problems than workers in larger businesses. © 2017 Wiley Periodicals, Inc.

Lead is a strong neurotoxin. The effects of lead on the activity of the autonomic nervous system, assessed by the use of heart rate variability (HRV) analysis, have not yet been established. To assess the effects of occupational chronic lead exposure on the autonomic nervous system activity. The study group consisted of 22 copper foundry workers (mean age 41.8+/-8.7 years) who had elevated parameters of lead overload and were admitted to the hospital for chelate therapy. The control group consisted of 13 age-matched healthy males. Lead concentration was measured with the use of atomic absorption spectrophotometry, and concentration of free protoporphyrins in erythrocytes (FEP) using a fluorometric method. Each patient underwent 24-hour ambulatory ECG monitoring, and standard short-term as well as long-term HRV parameters were obtained. There were no significant differences between patients and controls in HRV parameters. In the control group, HRV parameters correlated with age. In patients, a significant negative correlation between lead concentration and some short-term HRV parameters calculated during the night was found: SDNN (r=-0.48, p<0.05), TP (r=-0.48, p<0.01) and LF (r=-0.48, p<0.01). In patients, a negative correlation between lead concentration and HFnight/HFday index was found (r=-0.47 p<0.01), whereas in controls this correlation was positive (r=0.66 p<0.05). Overall HRV indices are similar in subjects exposed to lead and in healthy controls. A decrease in the physiological elevation of HF values during the night, together with an increase in lead blood concentration and lack of relationship between age and HRV parameters in workers chronically exposed to lead may suggest disturbances of the autonomic system. In subjects not exposed to lead a decrease in heart rate with an increase in FEP concentration was observed.

Suing the doctor: lawsuits by injured workers against the occupational physician.

PubMed

Postol, L P

1989-11-01

Occupational physicians are beginning to learn that they, like other physicians, can be targets for lawsuits. This article attempts to outline the relationship between the workers' compensation system and occupational physicians' personal liability. Consideration is given to potential liability due to malpractice, negligent interference with a workers' contractual relationship with his or her employer, libel and slander, and unauthorized release of information. The requirements of the Occupational Health and Safety Administration for medical examinations and recordkeeping are also highlighted. Finally, the need to clarify the relationship between the doctor, patient/worker, and employer is analyzed. Once the occupational physician recognizes the areas for liability, he or she can take practical steps to minimize his or her exposure.

We wanted to explore the risk of asthma among male workers of the construction industry. All Finnish male construction industry workers and all those employed in administrative work were followed for asthma incidence through a register linkage in 1986 through 1998. Age-adjusted relative risks (RR) were estimated for 24 construction occupations. The risk was increased in nearly all construction occupations studied, but it was highest among welders and flame cutters (RR 2.34), asphalt roofing workers (RR 2.04), plumbers (RR 1.90), and brick layers and tile setters (RR 1.83). Only 45 (2%) of the cases of asthma among construction workers had been recognized as occupational asthma. Construction industry workers have an increased risk of adult-onset persistent asthma and cases of occupational asthma caused by well-established causative agents have only a minor contribution to this overall asthma excess.

OBJECTIVES The aim of the present study was to evaluate the relation of smoking with anxiety and depression in workers who were exposed to occupational risk factors. For this purpose, working time, smoking status, nicotine dependence, and respiratory functions of the workers who were exposed to physical and/or chemical harmful substances were evaluated and the presence of anxiety/depression was investigated. MATERIAL AND METHODS Male workers who were exposed to occupational risk factors such as solvents, heavy metals, and dust and visited the outpatient clinic for occupational diseases within a one-year period were included. Pulmonary Function Test and Fagerström Test for Nicotine Dependence were performed. Anxiety and depression statuses of the workers were assessed using the Hospital Anxiety and Depression Scale. RESULTS The mean age of 665 male workers was 45 y (range, 38–48 y), and they were most commonly exposed to solvents (45.9%), followed by heavy metal fume/dust (20.9%). Of the workers, 252 (37.9%) had anxiety, 294 (44.2%) had depression, and 171 (25.7%) had both. More than half of the workers in each occupation/exposure group were smokers. Respiratory complaints were present in 34% of the workers. According to the regression analysis, the presence of respiratory system complaints was found to be a significant risk factor for anxiety, depression, and anxiety plus depression. CONCLUSION In conclusion, smoking and anxiety/depression were found to be the conditions affecting more than half of the workers with occupational exposure. PMID:29755811

Background: Dysmenorrhea, dyspareunia, and non-cyclic pelvic pain are health concerns for factory workers in China and may be increased by occupational stress. Objectives: To estimate the prevalence and demographic and occupational factors associated with three types of gynecologic pain among female factory workers in Tianjin. Methods: The study included 651 female workers from three factories in Tianjin, China. Logistic regression models were estimated to determine associations between occupational stress and gynecologic pain. Results: Occupational stress including high job strain, exhaustion, and stress related to working conditions was a risk factor for gynecologic pain. High job strain and poor job security were associated with an increased risk for dysmenorrhea. Compulsory overtime and exhaustion were associated with increased non-cyclic pelvic pain. Working overtime and exhaustion were associated with increased dyspareunia. Conclusions: As China’s population of female factory workers grows, research on the reproductive health of this population is essential. PMID:24804338

Occupational Deaths among Healthcare Workers

Eisenberg, Leon

2005-01-01

Recent experiences with severe acute respiratory syndrome and the US smallpox vaccination program have demonstrated the vulnerability of healthcare workers to occupationally acquired infectious diseases. However, despite acknowledgment of risk, the occupational death rate for healthcare workers is unknown. In contrast, the death rate for other professions with occupational risk, such as police officer or firefighter, has been well defined. With available information from federal sources and calculating the additional number of deaths from infection by using data on prevalence and natural history, we estimate the annual death rate for healthcare workers from occupational events, including infection, is 17–57 per 1 million workers. However, a much more accurate estimate of risk is needed. Such information could inform future interventions, as was seen with the introduction of safer needle products. This information would also heighten public awareness of this often minimized but essential aspect of patient care. PMID:16022771

The Attitude of Construction Workers toward the Implementation of Occupational Health and Safety (OHS)

2018-02-01

Construction industry refers to one of the industries dealing with high accident rate. Besides its outdoor workplace involving many workers who usually work manually, the workers’ work culture and less awareness of occupational health and safety (OHS) are attributed to the high accident rate. This study explores some construction workers who are involved in some construction projects in big cities such as Bandung and Jakarta. The questionnaire-given to the construction workers focusing on stone construction, wood construction, and finishing session-reveals that the construction workers knowledge and understanding of nine Occupational Health and Safety (OHS) aspects reach above 50%. However, does not appear to reflect their knowledge and understanding of Occupational Health and Safety (OHS). The results of Focus Group Discussion (FGD) and an in-depth interview show that the fallacious implementation of Occupational Health and Safety (OHS) is attributed to their traditional “work culture”.

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

While the immigrant collective in Spain has grown considerably in recent years, little is known about working conditions and their corresponding effects on occupational injury in this group. The objective of this study was to compare the incidences for both fatal and non-fatal injuries in foreign workers to that of Spanish workers in 2005, by autonomous community and economic activity. injury data came from the accident registry of the ministry of labor and social issues, and denominators were taken from available social security affiliation statistics from general and coal mining social security system. Incidence indices for fatal and non-fatal occupational injuries for foreign and spanish workers were calculated. In addition, relative risks and their 95% confidence intervals (95% CI) were calculated by autonomous community and economic activity, using spanish workers as the reference group. Overall, relative risk for occupational injury in foreign workers in 2005 was superior to base risk for both fatal (1.34; 95% CI: 1.11-1.62) and non-fatal injury (1.13; 95% CI: 1.13-1.14), though there were important differences by autonomous community and activity sectors. Compared with Spanish workers, risk for occupational injury was higher for foreign workers in industrial activities, while it was lower in construction, commerce and restaurants and hotels. By autonomous community, Aragón and Catalonia showed the highest risks for foreign workers. A higher risk for occupational injury among foreign workers is confirmed, and may be higher than that observed. The differences in risk among economic activities and autonomous communities require more detailed analysis.

Common mental disorders (CMD) have a major impact on both society and individual workers, so return to work (RTW) is an important issue. In The Netherlands, the occupational physician plays a central role in the guidance of sick-listed workers with respect to RTW. Evidence-based guidelines are available, but seem not to be effective in improving RTW in people with CMD. An intervention supporting the occupational physician in guidance of sick-listed workers combined with specific guidance regarding RTW is needed. A blended E-health module embedded in collaborative occupational health care is now available, and comprises a decision aid supporting the occupational physician and an E-health module, Return@Work, to support sick-listed workers in the RTW process. The cost-effectiveness of this intervention will be evaluated in this study and compared with that of care as usual. This study is a two-armed cluster randomized controlled trial, with randomization done at the level of occupational physicians. Two hundred workers with CMD on sickness absence for 4-26 weeks will be included in the study. Workers whose occupational physician is allocated to the intervention group will receive the collaborative occupational health care intervention. Occupational physicians allocated to the care as usual group will give conventional sickness guidance. Follow-up assessments will be done at 3, 6, 9, and 12 months after baseline. The primary outcome is duration until RTW. The secondary outcome is severity of symptoms of CMD. An economic evaluation will be performed as part of this trial. It is hypothesized that collaborative occupational health care intervention will be more (cost)-effective than care as usual. This intervention is innovative in its combination of a decision aid by email sent to the occupational physician and an E-health module aimed at RTW for the sick-listed worker.

Obesity Prevalence by Occupation in Washington State, Behavioral Risk Factor Surveillance System

2014-01-01

Introduction Data that estimate the prevalence of and risk factors for worker obesity by occupation are generally unavailable and could inform the prioritization of workplace wellness programs. The aims of this study were to estimate the prevalence of obesity by occupation, examine the association of occupational physical activity and a range of health behaviors with obesity, and identify occupations in which workers are at high risk of obesity in Washington State. Methods We conducted descriptive and multivariable analyses among 37,626 employed Washington State respondents using the Behavioral Risk Factor Surveillance System in odd numbered years, from 2003 through 2009. We estimated prevalence and prevalence ratios (PRs) by occupational groups adjusting for demographics, occupational physical activity level, smoking, fruit and vegetable consumption, and leisure-time physical activity (LPTA). Results Overall obesity prevalence was 24.6% (95% confidence interval [CI], 24.0–25.1). Workers in protective services were 2.46 (95% CI, 1.72–3.50) times as likely to be obese as workers in health diagnosing occupations. Compared with their counterparts, workers who consumed adequate amounts of fruits and vegetables and had adequate LTPA were significantly less likely to be obese (PR = 0.91; 95% CI, 0.86–0.97 and PR = 0.63; 95% CI, 0.60–0.67, respectively). Workers with physically demanding occupational physical activity had a lower PR of obesity (PR = 0.83; 95% CI, 0.78–0.88) than those with nonphysically demanding occupational physical activity. Conclusion Obesity prevalence and health risk behaviors vary substantially by occupation. Employers, policy makers, and health promotion practitioners can use our results to target and prioritize workplace obesity prevention and health behavior promotion programs. PMID:24406093

The aims of the present study were to analyze the association between incident stroke, occupational class and stress and to examine whether the association is found in both men and women in a prospective study of Japanese male and female workers. A total of 3190 male and 3363 female Japanese community-dwelling workers aged 65 or under with no history of cardiovascular disease were followed. Occupational stress was evaluated using a demand-control questionnaire. The impact on stroke was examined in stratified analyses of occupational classes. We identified 147 incident strokes (91 in men and 56 in women) during the 11-year follow-up period. Men with high strain jobs (combination of high job demand and low job control) were nearly three times more likely to suffer from a stroke than men with low strain jobs (combination of low job demand and high job control). Among male workers in low occupational classes (blue-collar and non-managerial work), job strain was associated with a higher risk of stroke. In contrast, there was no association between job strain and incident stroke among male workers in high occupational classes (white-collar and managerial work). No statistically significant differences were found for stroke incidence among the job characteristic categories in all the female participants. However, significant, over five-fold excess risks were found among white-collar and managerial female workers exposed to high job strain, compared with their counterparts with low strain jobs. Our study of Japanese workers provided supportive evidence for vulnerability to occupational stress among lower occupational class workers in males but not in females. Copyright © 2011 Elsevier Ltd.

This study aimed to investigate the association between occupational clusters and allergic rhinitis (AR). The study was based on data from the Korean National Health and Nutrition Examination Survey (KNHANES: 2007-2015). This study included 46,965 individuals: 20,491 men and 26,474 women. AR was defined as having been diagnosed by a physician. Occupations were classified according to occupational characteristics and skill levels into white (chief executives, senior officials, legislators, managers, professionals, and technicians), pink (clerks, clerical support workers, services and sales workers), blue (craft and related trades workers, drivers, plant and machine operators, assemblers, elementary occupation workers), and green (skilled agricultural, forestry, and fishery workers) categories. We calculated the odds ratios (ORs) and 95% confidence intervals (CIs) of AR according to the occupational clusters by using the chi-squared test and logistic regression. In the study population, 10.7% of the men and 13.5% of the women had AR. The prevalence of AR was highest among white-collar workers, followed by pink, blue, and green-collar workers. Compared to green-collar workers, among men the adjusted ORs of the blue, pink, and white-collar workers were 2.00 (95% CI 1.58-2.53), 2.46 (95% CI 1.91-3.15), and 2.78 (95% CI 2.20-3.51), respectively; and among women were 2.45 (95% CI 1.99-3.02), 2.64 (95% CI 2.15-3.25), and 3.63 (95% CI 2.96-4.47), respectively. This study suggests that AR prevalence is significantly associated with occupational clusters.

Contemporary and futuristic views of pollution control devices in foundries.

Foundry practices are used in contemporary world to produce large volume of components and products. Foundry practices involve the melting of metals and pouring the molten metal into the cavities called molds. On solidification, the metals which assume the shape of molds are removed as castings. Foundries that employ these practices were growing in large number till the middle part of the twentieth century in the world. After the middle part of the twentieth century, the world community begun to realize that, foundries were emitting pollutants which were affecting the health of humans. In order to overcome this situation, several countries in the world promulgated laws stipulating the maximum level of pollutants that can emit by foundries. These laws affected the functioning and growth of foundries. In order to sustain amidst these constraints, foundries begun to install energy efficient melting technologies and pollution control devices (PCDs). In this back ground, this paper reports to assess the contemporary scenario and project the future needs for sustaining the foundries. During the conduct of this literature review, it was discernable that, research papers have reported three categories of researches. In the first category of research papers, the researches reporting the achievement of cleaner production technologies in foundries using PCDs have appeared. In the second category of research papers, the application of cleaner production technology in foundries located in different countries has been examined. In the third category of research papers, the application of efficient melting technologies and PCDs in different clusters of foundries located in different parts of world has been explored. Subsequently implementation technics of Environmental Management System in cleaner production technics in foundries has been described the analysis of the information and knowledge drawn from these three categories of papers has revealed that, researches exploring the sustenance of foundries situated in different parts of world are required to be carried out intensively in future. The outcome of these researchers will be useful to apply the cleaner production technologies that would be suitable for implementation in different foundry clusters to suit the different conditions prevailing with regard to the adoption of efficient melting technologies and PCDs.

2018-06-01

The aim of this review was to identify, appraise and synthesize the best available evidence on the effectiveness of moisturizers, barrier creams, protective gloves, skin protection education and complex interventions (a combination of two or more of the interventions listed here) in preventing occupational irritant hand dermatitis (OIHD) in wet workers, comparing each intervention to an alternative intervention or to usual care (workers' regular skin care regimen). The most significant occupational skin problem potentially encountered in wet work occupations is occupational dermatitis. When the skin comes into contact with hazardous substances at work, this can cause occupational dermatitis. Substances which may cause occupational dermatitis include cleaning products, organic solvents, metalworking fluids, cement, flour, adhesives, other chemicals and even certain plants. Occupational skin disease has adverse effects on quality of life and the long term prognosis for skin health is poor unless workplace exposures are addressed. To date, no systematic review has been undertaken to determine the effectiveness of interventions for the primary prevention of OIHD in wet workers. The review included any workers from healthcare (e.g. nurses, doctors and allied health professionals) and also people in different wet work occupations (e.g. hairdressers, florists, catering workers, metal workers) at similar risk of OIHD. Studies that assessed the following interventions in the primary prevention of OIHD in wet workers at the workplace and at home (before and after work) were included:Types of studies considered were experimental study designs including randomized controlled trials, non-randomized controlled trials, quasi-experimental, and before and after studies. Primary outcome measures were OIHD incidence, and secondary outcome measures were product evaluation and change of occupation because of OIHD versus staying in the occupation. Published and unpublished literature in the English language was sought between 2004 and 2017. The databases searched included: COCHRANE CENTRAL, MEDLINE, CINAHL, AMED and Embase. The search for unpublished studies included: Google Scholar, Open DOAR and Robert Gordon University's thesis database, "OPEN AIR". There were no studies located that met the inclusion requirements of this review. There is currently no evidence available to determine the effectiveness of interventions to prevent OIHD amongst wet workers that met this review's inclusion criteria.

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.

Occupational contact dermatitis (OCD) is a common occupational disease. Evidence suggests that education and training are effective prevention strategies. In spite of these known prevention strategies, workers continue to develop OCD. Little is reported regarding the actual training experience of workers. To examine the training experience of workers with contact dermatitis to identify areas for improvement. Participants were workers being assessed for contact dermatitis in an occupational health clinic. The anonymous survey collected demographics, workplace characteristics, and education and prevention practices. Approximately 80% reported general occupational health and safety training; however, only 49% reported skin-specific training (SST). For workers reporting SST, most received information regarding exposure avoidance, hand washing, and glove use. This content was reported as helpful by at least 50%. Workers who did not receive SST indicated the most important content would be warning signs of skin problems, how to avoid exposure and skin care while using gloves. While the study was anonymous and used self-reported of training experience, the study suggests there are gaps in skin protection training. Addressing these gaps may lead to improved prevention and reduction in OCD. © The Author(s) 2017. Published by Oxford University Press on behalf of the British Occupational Hygiene Society.

1995-08-01

A mobile thermal foundry sand reclamation unit was designed and constructed. This unit consisted of thermal and mechanical sand reclamation equipment installed on the bed of a 50 foot low-boy trailer. It was transported to a number of Midwest foundries for on-site demonstration of the sand reclamation process. This allowed participating foundries to have their own refuse sand (10-100 tons) processed and then reused in production for evaluation. The purpose for building the unit was to demonstrate to foundries through ``hands on`` experience that refuse sands can be reclaimed and successfully reused particularly in regard to product quality. Most ofmore » the participating foundries indicated a high level of satisfaction with the reclaimed sand. Laboratory testing of samples of the used sand, before and after processing by the demonstration unit, verified the usability of the reclaimed sand. One of the foundries participating was a brass foundry, the sand from this foundry contained lead and is classified as a hazardous material. After reclamation the sand was no longer hazardous and could also be reused in the foundry.« less

In the distribution service industry, sales people often experience multiple occupational stressors such as excessive emotional labor, workplace mistreatment, and job insecurity. The present study aimed to explore the associations of these stressors with depressive symptoms among women sales workers at a clothing shopping mall in Korea. A cross sectional study was conducted on 583 women who consist of clothing sales workers and manual workers using a structured questionnaire to assess demographic factors, occupational stressors, and depressive symptoms. Multiple regression analyses were performed to explore the association of these stressors with depressive symptoms. Scores for job stress subscales such as job demand, job control, and job insecurity were higher among sales workers than among manual workers (p < 0.01). The multiple regression analysis revealed the association between occupation and depressive symptoms after controlling for age, educational level, cohabiting status, and occupational stressors (sβ = 0.08, p = 0.04). A significant interaction effect between occupation and social support was also observed in this model (sβ = −0.09, p = 0.02). The multiple regression analysis stratified by occupation showed that job demand, job insecurity, and workplace mistreatment were significantly associated with depressive symptoms in both occupations (p < 0.05), although the strength of statistical associations were slightly different. We found negative associations of social support (sβ = −0.22, p < 0.01) and emotional effort (sβ = −0.17, p < 0.01) with depressive symptoms in another multiple regression model for sales workers. Emotional dissonance (sβ = 0.23, p < 0.01) showed positive association with depressive symptoms in this model. The result of this study indicated that reducing occupational stressors would be effective for women sales workers to prevent depressive symptoms. In particular, promoting social support could be the most effective way to promote women sales workers’ mental health. PMID:29168777

[Occupational risk related to optical radiation exposure in construction workers].

PubMed

Gobba, F; Modenese, A

2012-01-01

Optical Radiation is a relevant occupational risk in construction workers, mainly as a consequence of the exposure to the ultraviolet (UV) component of solar radiation (SR). Available data show that UV occupational limits are frequently exceeded in these workers, resulting in an increased occupational risk of various acute and chronic effects, mainly to skin and to the eye. One of the foremost is the carcinogenic effect: SR is indeed included in Group 1 IARC (carcinogenic to humans). UV exposure is related to an increase of the incidence of basal cell carcinoma, squamous cell carcinoma of the skin and cutaneous malignant melanoma (CMM). The incidence of these tumors, especially CMM, is constantly increasing in Caucasians in the last 50 years. As a conclusion, an adequate evaluation of the occupational risk related to SR, and adequate preventive measures are essential in construction workers. The role of occupational physicians in prevention is fundamental.

To examine nonwage losses after occupational injury among health care workers and the factors associated with the magnitude of these losses. Inception cohort of workers filing an occupational injury claim in a Canadian province. Worker self-reports were used to calculate (1) the nonwage economic losses in 2010 Canadian dollars, and (2) the number of quality-adjusted days of life lost on the basis of the EuroQOL Index. Most workers (84%; n = 123) had musculoskeletal injuries (MSIs). Each MSI resulted in nonwage economic losses of Can$3131 (95% confidence interval, Can$3035 to Can$3226), lost wages of Can$5286, and 7.9 quality-adjusted days of life lost within 12 weeks after injury. Losses varied with type of injury, region of the province, and occupation. Non-MSIs were associated with smaller losses. These estimates of nonwage losses should be considered in workers' injury compensation policies and in economic evaluation studies.

Objective We describe the socio-demographic, occupational, and health characteristics of “green collar” workers, a vital and emerging workforce in energy-efficiency and sustainability. Methods We linked data from the 2004–2012 National Health Interview Surveys (NHIS) and US Occupational Information Network (O*NET). Descriptive and logistic regression analyses were conducted using green collar worker status as the outcome (n=143,346). Results Green collar workers are more likely than non-green workers to be male, age 25–64y, obese, and with ≤ high school education. They are less likely to be racial/ethnic minorities and employed in small companies or government jobs. Conclusions Green collar workers have a distinct socio-demographic and occupational profile, and this workforce deserves active surveillance to protect its workers’ safety. The NHIS-O*NET linkage represents a valuable resource to further identify the unique exposures and characteristics of this occupational sector. PMID:28403016

This study examined the changes in the hematological index caused by low-dose medical radiation exposure in workers in a medical radiation-exposed environment. The cumulative dose was obtained using thermoluminescent dosimeters over a 9-year period, and the changes in hematological index count (red blood cells (RBCs), hemoglobin, platelets, white blood cells (WBCs), monocytes, lymphocytes, neutrophils, basophils, and eosinophils) were examined in both the occupational workers and controls. In total, 370 occupational workers and 335 controls were compared. The analysis led to the following observations: (1) The average cumulative dose in males and females was 9.65±15.2 and 4.82±5.55 mSv, respectively. (2) In both males and females, there was a very low correlation between the occupation period and the cumulative dose (r<±0.25). (3) When the occupation period was longer, the WBC counts both decreased and increased in the male workers and the RBC counts were lower in the workers than in the control group (p<0.05). In females, the WBC counts both decreased and increased in the workers and the eosinophil counts were lower in the workers than in the control group (p<0.01). (4) When the cumulative dose was large, the lymphocyte counts decreased in male workers and the platelet count was lower in the workers than in the control group (p<0.05). In females, the lymphocyte count and RBC count were lower in the workers than in the control group (p<0.05). Abnormal distributions of some blood indices were observed in the occupational radiation workers compared with the controls. Attempts were made to limit radiation exposure to personnel, but the employees did not always follow the preset rules. Actually, the adverse effects of low-level radiation were attributed to probability. Overall, workers should obey the radiation protection regulations provided by the government and a national system of radiation protection is needed.

Objectives Although compensation for occupational injuries and diseases is guaranteed in almost all nations, countries vary greatly with respect to how they organize workers' compensation systems. In this paper, we focus on three aspects of workers' compensation insurance in Organization for Economic Cooperation and Development (OECD) countries - types of systems, employers' funding mechanisms, and coverage for injured workers - and their impacts on the actual frequencies of occupational injuries and diseases. Methods We estimated a panel data fixed effect model with cross-country OECD and International Labor Organization data. We controlled for country fixed effects, relevant aggregate variables, and dummy variables representing the occupational accidents data source. Results First, the use of a private insurance system is found to lower the occupational accidents. Second, the use of risk-based pricing for the payment of employer raises the occupational injuries and diseases. Finally, the wider the coverage of injured workers is, the less frequent the workplace accidents are. Conclusion Private insurance system, fixed flat rate employers' funding mechanism, and higher coverage of compensation scheme are significantly and positively correlated with lower level of occupational accidents compared with the public insurance system, risk-based funding system, and lower coverage of compensation scheme.

Objectives Several epidemiologic studies have suggested that certain paternal occupations may be associated with an increased prevalence of birth defects in offspring. Using data from the National Birth Defects Prevention Study, we investigated the association between paternal occupation and birth defects in a case-control study of cases comprising over 60 different types of birth defects (n = 9998) and non-malformed controls (n = 4066) with dates of delivery between 1997 and 2004. Methods Using paternal occupational histories reported by mothers via telephone interview, jobs were systematically classified into 63 groups based on shared exposure profiles within occupation and industry. Data were analyzed using Bayesian logistic regression with a hierarchical prior for dependent shrinkage to stabilize estimation with sparse data. Results Several occupations were associated with an increased prevalence of various birth defect categories, including: mathematical, physical and computer scientists; artists; photographers and photo processors; food service workers; landscapers and groundskeepers; hairdressers and cosmetologists; office and administrative support workers; sawmill workers; petroleum and gas workers; chemical workers; printers; material moving equipment operators; and motor vehicle operators. Conclusions Findings from this study might be used to identify specific occupations worthy of further investigation, and to generate hypotheses about chemical or physical exposures common to such occupations.

2018-04-01

In 2015, approximately 244 million people were transnational migrants, approximately half of whom were workers, often engaged in jobs that are hazardous to their health. They work for less pay, for longer hours, and in worse conditions than do nonmigrants and are often subject to human rights violations, abuse, human trafficking, and violence. Worldwide, immigrant workers have higher rates of adverse occupational exposures and working conditions, which lead to poor health outcomes, workplace injuries, and occupational fatalities. Health disparities of immigrant workers are related to environmental and occupational exposures and are a result of language/cultural barriers, access to health care, documentation status, and the political climate of the host country. Recommendations on global and local scales are offered as potential solutions to improving the health of immigrant workers.

An epidemiological study of occupational dermatitis in a tyre company and a cement company is reported. Ninety-seven percent of 999 tyre workers and 78% of 151 cement workers were screened by an occupational nurse and subsequently assessed by a specialist dermatologist. Prevalence rates of occupational contact dermatitis were 37 per 1000 and 68 per 1000 in the tyre and cement companies, respectively. Maintenance workers and tyre builders - particularly if they were Yugoslav and female - had high prevalence rates amongst tyre workers. Worker's compensation claim rates for the tyre company are similar to U.K. and U.S. rates for this industry. Prevalence rates of 37 per 1000 can be considered as a lower limit for this industry. The high prevalence rates in the cement company are noteworthy and require further study.

Workers in the temporary staffing industry face hazardous working conditions and have a high risk of occupational injury. This project brought together local workers' centers and university investigators to build a corps of Occupational Health Promoters (OHPs) and to test a survey tool and recruitment methods to identify hazards and raise awareness among workers employed by temporary staffing companies. OHPs interviewed ninety-eight workers employed by thirty-three temporary agencies and forty-nine client companies, working mainly in shipping and packing, manufacturing, and warehousing sectors. Surveys identified workplace hazards. OHPs reported two companies to OSHA, resulting in several citations. Partners reported greater understanding of occupational safety and health challenges for temporary workers and continue to engage in training, peer education, and coalition building.

Research has infrequently looked beyond the injured worker when gauging the burden of occupational injury. We explored the relationship between occupational injury and musculoskeletal disorders (MSDs) among family members of injured workers. We used 2005 and 2006 Truven Health Analytics databases, which contain information on workers' compensation and family healthcare claims. We used descriptive analyses, and negative binomial and two-part models. Family members of severely injured workers had a 15% increase in the total number of MSD outpatient claims and a 34% increase in the mean cost of MSD claims compared to family members of non-severely injured workers within 3 months after injury. Extrapolating cost results to the national level implies that severe occupational injury would be associated with between $29 and $33 million additional cost of family member outpatient MSD claims. Occupational injury can impose a formerly unrecognized health burden on family members of injured workers. Published 2015.

Objectives The aim of this study was to estimate prevalence of injury by occupation and industry and obesity’s role. Methods Self-reported injuries were collected annually for US workers during 2004 to 2013. Prevalence ratios (PRs) and 95% confidence intervals (CIs) were obtained from fitted logistic regression models. Results Overall weighted injury prevalence during the previous three months was 77 per 10,000 workers. Age-adjusted injury prevalence was greatest for Construction and Extraction workers (169.7/10,000) followed by Production (160.6) among occupations, while workers in the Construction industry sector (147.9) had the highest injury prevalence followed by the Agriculture/Forestry/Fishing/Mining/Utilities sector (122.1). Overweight and obese workers were 26% to 45% more likely to experience injuries than normal-weight workers. Conclusion The prevalence of injury, highest for Construction workers, gradually increased as body mass index levels increased in most occupational and industry groups. PMID:27058472

Investigating the status of work ability and occupational stress in 1030 chemistry workers at levels of chemical materials and explore their relationship and influence factors (481 workers of study group, 549 workers of control group). Work ability and occupational stress were measured with the work ability index (WAI) and occupational stress questionnaire (OSQ). The risk factors of work ability decline were evaluated. WAI and OSQ scores scores are significantly different between study group and control group (P < 0.01), and work ability correlated inversely with occupational stress (P < 0.01). The WAI scores are reducing with a higher of the OSQ. The work ability of chemistry-workers became lower with the increasing of age. Variables that influence work ability included the factors of disorder of musculoskeletal function (OR = 2.884), assessment of the current health (OR = 2.651), the diseases (OR = 2.498), emotion status (OR = 2.407), physical load (OR = 1.254) and lack of exercise (OR = 1.956). The stress levels and stress factors had affected work ability in chemistry-workers, and it was suggested that the findings could be helpful for the measures protecting and promoting of work ability on the health of workers.

The construct validity of the Job Content Questionnaire (JCQ) psychological demands scale in relationship to physical demands has been inconsistent. This study aims to test quantitatively and qualitatively whether the scale validity differs by occupation. Hierarchical clustering analyses of 10 JCQ psychological and physical demands items were conducted in 61 occupations from two datasets: one of non-faculty workers at a university in the United States (6 occupations with 208 total workers) and the other of a Belgian working population (55 occupations with 13,039 total workers). The psychological and physical demands items overlapped in 13 of 61 occupation-stratified clustering analyses. Most of the overlaps occurred in physically-demanding occupations and involved the two psychological demands items, 'work fast' and 'work hard'. Generally, the scale reliability was low in such occupations. Additionally, interviews with eight university workers revealed that workers interpreted the two psychological demands items differently by the nature of their tasks. The scale validity was occupation-differential. The JCQ psychological job demands scale as a job demand measure has been used worldwide in many studies. This study indicates that the wordings of the 'work fast' and 'work hard' items of the scale need to be reworded enough to differentiate mental and physical job demands as intended, 'psychological.'

Occupational health management plays an important role in the prevention of provider-to-patient transmission in healthcare workers infected with human immunodeficiency virus (HIV), hepatitis B virus (HBV), and/or hepatitis C virus (HCV). Therefore, the Japan Society for Occupational Health's Research Group on Occupational Health for Health Care Workers has proposed a consensus for the management of healthcare workers infected with HIV, HBV, and/or HCV based on recent evidence for each concerned group. The consensus recommends that: (1) employers in medical institutions should establish a policy of respecting the human rights of healthcare workers, management strategies for occupational blood exposure, and occupational health consultation; (2) occupational health staff should appropriately assess the risk of provider-to-patient transmission of HIV, HBV, and/or HCV infection and rearrange their tasks if necessary. When conducting risk assessment, occupational health staff should obtain informed consent and then cooperate with the physician in charge as well as infection control experts in the workplace; (3) healthcare workers infected with HIV, HBV, and/or HCV should disclose their employment to their treating physician and consult with their doctor regarding the need for special considerations at work; and (4) supervisors and colleagues in medical institutions should correctly understand the risks of HIV, HBV, and HCV infection and should not engage in any behavior that leads to discrimination against colleagues infected with HIV, HBV, and/or HCV.

The study was undertaken to evaluate the environmental exposure to polycyclic aromatic hydrocarbons in subjects living in the area of recycling electronic garbage in Southern China and research the influence of environment smoke tobacco (EST) to people through active and passive smoking. Urinary concentrations of 2-hydroxynaphthalene, 2-hydoxyfluorene, 9-hydroxyphenanthrene, and 1-hydroxypyrene were determined in 141 randomly selected voluntary residents aged 13 to 81 years in two polycyclic aromatic hydrocarbon (PAH)-exposed groups, two control groups, and an EST research group. The concentrations of 2-hydroxynaphthalene, 2-hydoxyfluorene, 9-hydroxyphenanthrene, and 1-hydroxypyrene in PAH-exposed groups are significantly higher (p<0.05) than those of control groups. Mean value of 1-hydroxypyrene in the residents living in the area of recycling electronic garbage (1.1 μmol/mol creatinine) is a little higher than those of iron foundry workers, automobile repair workers, and firefighters. Mean value of 2-hydroxynaphthalene (11.3 μmol/mol creatinine) is much higher than that of shipyard and aircraft maintenance and much lower than some occupational exposure, such as coking batteries, sorting department, and distillation department in coking plant. Some metabolites of PAHs (PAHm) are significantly elevated through active and passive smoking, while the influence of EST to other PAHm is not statistically significant. 2-Hydroxynaphthalene, 2-hydoxyfluorene, 9-hydroxyphenanthrene, and 1-hydroxypyrene in the urine of smokers are, respectively, 3.9, 1.9, 1.4, and 1.9 times to those of nonsmokers. In nonsmokers, passive smokers excreted 1.1, 1.5, 1.9, and 1.5 times of 2-hydroxynaphthalene, 2-hydoxyfluorene, 9-hydroxyphenanthrene, and 1-hydroxypyrene compared to nonpassive smokers.

Employee’s occupational stress and safety performance are highly related, which has been generally recognized by the researchers. We did this research to understand the status of the stress for construction workers, and explore the influence factors of pressure source with characteristics of construction industry. Based on the results of previous studies, we designed questionnaire to collect the influence factors on occupational stressors. The study selected workers from certain construction units at the grass-roots level as sample source. According to the results of the questionnaire, we redesigned the interview outline, and did the semi-structured interviews on workers randomly selected. Finally, we developed a scale which combined the characteristics of construction projects in China. Using SPSS software for factor analysis, reliability analysis, and descriptive statistical analysis, the results show that there are six factors affecting the workers’ occupational stress, including The Work Itself, Family-Work, Career Development, Organization Style, Interpersonal Relationship and Role Management Style. The work itself is the main sources of occupational stress. The results can be used by the construction company to provide guidance for workers to control and manage occupational stress.

Agricultural workers' health depends on many factors: working conditions, security arrangements, medicine, quality of drugs, the environment, etc. Occupational injuries and diseases are also among the factors that can negatively affect their health. To analyze provisions of the international legislation and scientific literature concerning existence of restrictions on impact of occupational injuries and diseases on agricultural workers' health. International acts, data of international organizations and conclusions of scientists have been examined and used in the study. The article also integrates information from scientific journals and monographs from a medical and legal point of view with scientific methods. This article is based on dialectical, comparative, analytic, synthetic and comprehensive research methods. Impact of occupational injuries and diseases on agricultural workers' health has been studied within the system approach, as well as analysis and synthesis. The level of occupational morbidity, traumatism and above all standard of agricultural workers' health depends on the way of occupational safety organization. Working conditions and safety in agricultural industry and therefore the appropriate standard of health remain unsatisfactory in many countries.

To study the relationship between occupational stress and psychological health state among oil workers. 1,230 oil workers in 122 work types of oil industry were selected and written occupational stress questionary(OSQ) and symptom check list (SCL-90). Petroleum workers' psychological health states were poor with increasing occupational stress degree. The scores in physical symptoms(1.87 +/- 0.80, 1.72 +/- 0.70), depression(1.74 +/- 0.76, 1.62 +/- 0.67), horror(1.48 +/- 0.65, 1.39 +/- 0.55) in the high and medium stress group were obviously higher than those in low stress group(1.55 +/- 0.61, 1.43 +/- 0.54, 1.28 +/- 0.46, respectively, P < 0.05). The score of mood state in the high and medium stress group was obviously higher than that in low stress group(P < 0.05). Psychological health states and mood state in the petroleum workers with short service length are significantly poorer than that with long service length(P < 0.01). Occupational stress should affect psychological health state of petroleum workers.

Falls are a leading cause of occupational injury for workers in healthcare, yet the risk factors of falls in this sector are understudied. Falls resulting in workers' compensation for time-loss from work from 2004-2007 for healthcare workers in British Columbia (BC) were extracted from a standardised incident-reporting database. Productive hours were derived from payroll data for the denominator to produce injury rates; relative risks were derived through Poisson regression modelling. A total of 411 falls were accepted for time-loss compensation. Compared to registered nurses, facility support workers (risk ratio (95% CI) = 6.29 (4.56-8.69)) and community health workers (6.58 (3.76-11.50)) were at high risk for falls. Falls predominantly occurred outdoors, in patients' rooms and kitchens depending on occupation and sub-sector. Slippery surfaces due to icy conditions or liquid contaminants were a leading contributing factor. Falls were more frequent in the colder months (January-March). The risk of falls varies by nature of work, location and worker demographics. The findings of this research will be useful for developing evidence-based interventions. STATEMENT OF RELEVANCE: Falls are a major cause of occupational injury for healthcare workers. This study examined risk factors including occupation type, workplace design, work setting, work organisation and environmental conditions in a large healthcare worker population in BC, Canada. The findings of this research should contribute towards developing evidence-based interventions.

There has been increasing interest in dietary health promotion in the workplace. Although many previous studies have focused on dietary habits in specific occupations, variation between occupational groups requires clarification. The present study aimed to examine differences in food and nutrient intake between occupational groups, using detailed classification. A cross-sectional study was conducted using data from the Japan Environment and Children's Study. The study included 38,721 employed Japanese expectant fathers aged between 20 and 65 years. Dietary intake was assessed using a food frequency questionnaire. Occupations were categorized into 11 categories according to the Japan Standard Occupational Classification. Analysis of variance and analysis of covariance were performed to compare dietary intake of occupational groups. Logistic regression analysis was performed to examine the differences in adherence to dietary recommendations across occupations. Dietary intake differed significantly between occupations. Specific dietary intake was observed in security and agricultural workers, who tended to exhibit higher consumption levels for numerous foods and nutrients. In addition, relative to other workers, security workers showed higher intake of dairy products and calcium, and agricultural workers consumed larger amounts of pickles and salt. The study categorized occupations into detailed categories using the Japan Standard Occupational Classification, which facilitated the clarification of overall dietary trends across occupations and identification of specific dietary characteristics in individual occupations. The findings could aid in workplace health promotion.

Occupational Safety and Health and Healthy Housing: A Review of Opportunities and Challenges.

PubMed

Jacobs, David E; Forst, Linda

Occupational safety and health (OSH) risks in construction of healthy housing (HH) have not been examined and collaboration between HH and OSH professionals is inadequate. The World Health Organization is developing international HH guidelines and the International Labour Organization is working to improve OSH in construction globally. We searched for exemplary reports (including gray literature) on construction hazards; preventive measures for occupants and workers; OSH frameworks, laws, and regulations; definitions; and HH. Healthy housing construction typically improves ventilation, moisture and mold, pest control, injury hazards, cleanability, maintenance, accessibility, thermal conditioning, and avoidance of toxic building materials. To date, this work is done without explicit requirements for worker health. Construction is among the most hazardous sectors around the globe, although protective measures are well known, including engineering and administrative controls and provision of personal protective equipment. Residential construction, renovation, repair, and maintenance are fragmented, consisting mostly of small companies without proper OSH training, equipment, and knowledge of HH principles. Residential construction is often undertaken by informal or unauthorized workers, putting them at high risk. Reduced exposure to toxic building materials is an example of a benefit for both workers and occupants if OSH and HH collaboration can be improved. By recognizing that homes under new construction or renovation are both a workplace and a residence, HH and OSH initiatives can apply public health principles to occupants and workers simultaneously. This article publishes key definitions, hazards and interventions common to both fields. A global increase in residential construction and renewed global interest in HH poses both risks and opportunities for primary prevention. Policy and practice interventions can benefit the health of occupants and those who work on their homes. Improvements in legislation, regulation, and international frameworks are needed to maximize OSH and HH collaboration and realize significant cobenefits. Occupational safety and health and HH standards should include requirements to protect both workers and occupants. Because homes can also be workplaces, both workers and housing occupants will receive important cobenefits when OSH and HH standards use proven interventions to protect workers and occupants.

The article covers changes in occupational cardiovascular risk for workers of nonferrous,metallurgy. Findings are that exposure to noise up to 94 dB with length of service increases possible atherosclerosis and metabolic syndrome. With 5 years of service, risk of the predicted conditions increases by 40.5%. When occupational exposure lasts over 5 years, risk of arterial hypertension increases. A group of workers without exposure to occupational factors appeared to have no connection between length of service and metabolic syndrome and arterial hypertension. Risk evolution modelling proved that risk of functional disorders in nonferrous metallurgy workers becomes unacceptable after 5 years of service (cardiovascular disorders are critical).

Immigrant workers in the United States: recent trends, vulnerable populations, and challenges for occupational health.

PubMed

McCauley, Linda A

2005-07-01

Immigrant workers are a rapidly growing segment of the U.S. work force, and these increasing numbers have resulted in a different ethnic mix in the work force than in previous decades. Immigrant workers are not a homogenous group, but are over-represented in low-paying occupations. Their diversity and vulnerability present distinct challenges for occupational health nurses. High-risk occupations in which a large proportion of immigrant workers are hired include agriculture, sweatshops, day laborers, and construction. Initiatives needed to improve the working conditions of this vulnerable population include improved surveillance and research, culturally competent care providers, improved health care access, advocacy, and changes in immigration and health policy.

Depression as a psychosocial consequence of occupational injury in the US working population: findings from the medical expenditure panel survey

PubMed Central

2013-01-01

Background Empirical evidence describing the psychosocial consequences of occupational injury is still limited. The effect of occupational injury on depression might pose unique challenges in workers compared with other kinds of injury. This study aimed to assess the differential impact of workplace injury compared with non-workplace injury on depression over time, and to identify the potential risk factors associated with post-injury depression in the US working population. Methods Using pooled panel data from the Medical Expenditure Panel Survey 2000–2006, a total of 35,155 workers aged 18–64 years who had been followed for about 18 months in each panel were analyzed. Injuries in the 4–5 months before baseline, and subsequent depression incidence during follow-up, were identified using ICD-9 codes for the medical conditions captured in personal interviews. A discrete time-proportional odds model was used. Results A total of 5.5% of workers with occupational injury at baseline reported depression at follow-up, compared with 4.7% of workers with non-occupational injury and 3.1% of workers without injuries. Those with occupational injuries had more severe injuries and required longer treatment, compared with those with non-occupational injuries. Only 39% of workers with workplace injuries were paid Workers’ Compensation (WC). The association between injury and depression appeared to be stronger for workplace injury, and the adjusted odds ratio for depression was 1.72 for those with occupational injury (95% CI: 1.27–2.32), and 1.36 for those with non-occupational injury (95% CI: 1.07–1.65) compared with the no-injury group, after controlling for relevant covariates. Occupational injury was associated with higher odds of developing depression over time. WC as a source of medical payment was associated with 33% higher odds of developing depression (95% CI: 1.01–1.74). Part-time work, shorter job tenure, and long working hours were independently associated with post-injury depression risk. Conclusions Workers with occupational injury were more likely to become depressed than those with non-occupational injury. The psychosocial consequences of occupational injury, including depression, deserve further exploration to adequately support those injured at work. This finding also emphasizes a need for early intervention to reduce the burden of depression associated with occupational injury. PMID:23560685

The restaurant industry is a rapidly growing sector in Singapore and workers in this industry are trained in culinary skills but not on recognition of safety and health hazards and their control measures. Anecdotal clinical evidence has suggested an increased prevalence of occupational dermatoses among restaurant workers. To determine the prevalence and risk factors for contact dermatitis and burns among restaurant, catering and fast-food outlet (FFO) staff. Workers were interviewed and then clinical examination and patch and/or prick tests were conducted in selected individuals. In total, 335 of 457 workers (73% response) were interviewed and 65 (19%) had occupational dermatitis or burns and were examined. Of these, contact dermatitis was the commonest diagnosis, with a 12-month period prevalence of 10% (35 workers) and 3-month period prevalence of 8% (26 workers). All 35 workers had irritant contact dermatitis (ICD) and there were no cases of allergic contact dermatitis. The adjusted prevalence rate ratios of risk factors for ICD were 2.78 (95% CI 1.36-5.72) for frequent hand washing >20 times per day, 3.87 (95% CI 1.89-7.93) for atopy and 2.57 (95% CI 1.21-5.47) for contact with squid. The 3-month period prevalence for burns was 6% (20 workers). Ten workers had other occupational dermatoses such as work-related calluses, paronychia, heat rash and allergic contact urticaria to prawn and lobster. ICD and burns are common occupational skin disorders among restaurant, catering and FFO workers.

Substance abuse is a serious problem, because it affects both workers and young people. Prevalence and consequences of cannabis abuse among construction workers in particular are not well studied in Egypt. To determine the association between non-fatal occupational injuries among construction workers and their demographic and occupational factors and to assess the frequency of cannabis abuse and its relationship to injury severity and workdays lost. A case-control study was conducted at Mansoura Emergency Hospital. Cases were 100 acutely injured male workers. A control group of 90 healthy age-matched workers was selected from 8 construction sites. Workers were interviewed, and a questionnaire was completed that included socio-demographic data, full occupational history, and causes and type of injury. Injury outcome measures included lost workdays and the injury severity score (ISS). Cannabis abuse in injured workers was monitored by preliminary testing of urine and confirmatory testing of blood. Logistic regression analysis revealed that the independent predictors of occupational injuries were rural residence, being a carpenter or painter and past history of injuries. The most common accidents were slipping falls (62%). Confirmed cannabis test was positive in 51.1% of the injured workers. Median days away from work were greater among cannabis users than non-users. The ISS was significantly higher among users compared to non-users ( p < 0.05). Cannabis abuse can increase injury severity and prolong workdays lost. Drug testing is recommended for at-risk construction workers with inadequate safety measures.

Few studies have simultaneously addressed the role of occupational factors, individual characteristics and living conditions in occupational injuries, and to the best of our knowledge none on railway workers. This survey assessed the roles of these factors in various types of injuries and for various jobs in French railway workers. This case-control study was conducted on 1,305 male workers with an occupational injury during a one-year period and 1,305 male controls. A standardized questionnaire was administrated by an occupational physician. Data were analyzed by the logistic regression method. The significant factors found for all the injuries combined were: young age (<30 yr) (adjusted odds ratio 1.47, 95% CI 1.01-2.14), 5 yr or less in present job (1.43, 1.15-1.78), sleep disorders (1.30, 1.08-1.57), current smoker (1.27, 1.08-1.50), and no do-it-yourself or gardening activity (1.23, 1.02-1.48). Young age, sleep disorders, and smoking were common for several types of injuries. The role of these factors differed between various job categories. Among injured workers sick leaves of eight days or over were more frequent in current smokers and overweight subjects. In conclusion, young age, lack of experience, job dissatisfaction, sleep disorders, smoking, and lack of physical activity increase the risk of occupational injuries. The risks induced were related with jobs. Preventive measures concerning work conditions and these factors could be conducted in railway workers generally, and especially in workers most at risk. The occupational physician could make workers more sensitive to these risks and help them to improve their living conditions during medical examinations.

The aim of the present study was to investigate the personal variability in occupational exposure to NO(2), as a marker of exposure to diesel exhaust, and to compare a statistical method of grouping workers in homogenous groups with a grouping performed by a qualified occupational hygienist. Forty-seven workers exposed to motor exhaust in their occupation were included. Personal measurements of NO(2) were performed with diffusive samplers over three full working shifts. The results from the measurements were analysed with a linear mixed effects model, taking both between and within-worker variability into consideration. The workers were divided into occupational groups in different ways in order to find a categorization, with maximal homogeneity in exposure in each group. We used (B)R(0.95) as an estimator of the between-worker variability. To study the effect of the divisions on the fit of the statistical model, we used the Akaike Information Criterion. The geometric mean for NO(2) for all 47 workers was 69 μg/m(3) and the between-worker variability (B)R(0.95) was 23.8. In six successive steps, the 47 workers were divided into up to eight groups, based on observed job characteristics. In the final grouping, seven groups were included with geometric means ranging from 32 μg/m(3) for outdoor workers, to 316 μg/m(3) for the most exposed group (tunnel construction workers). The (B)R(0.95) varied between 2.4 and 6.3. The within-worker variability (W)R(0.95) for the last division differed in the groups from 2.0 to 7.9. The Akaike Information Criterion decreased from 246, if all persons were included in one group, to 174 for the final grouping. The average level of NO(2) varied about 10 times between the different occupational groups, with the highest level for tunnel construction workers (316 μg/m(3)) and lowest for outdoor workers (32 μg/m(3)). For four of the seven groups the between-worker variability was higher than the within-worker variability. Copyright © 2010 Elsevier GmbH. All rights reserved.

To compare occupational psychosocial hazards in green collar versus non-green collar workers. Standard Occupational Classification codes were used to link the 2010 National Health Interview Survey to the 2010 Occupational Information Network Database. Multivariable logistic regressions were used to predict job insecurity, work life imbalance, and workplace harassment in green versus non-green collar workers. Most participants were white, non-Hispanic, 25 to 64 years of age, and obtained greater than a high school education. The majority of workers reported no job insecurity, work life imbalance, or workplace harassment. Relative to non-green collar workers (n = 12,217), green collar workers (n = 2,588) were more likely to report job insecurity (Odds ratio [OR] = 1.13; 95% confidence interval [CI] = 1.02 to 1.26) and work life imbalance (1.19; 1.05 to 1.35), but less likely to experience workplace harassment (0.77; 0.62 to 0.95). Continuous surveillance of occupational psychosocial hazards is recommended in this rapidly emerging workforce.

Marble workers are occupationally exposed to intense environmental marble dust in their workplace. We aimed to investigate the effect of occupational marble dust exposure on nasal mucociliary transport rate (NMTR). Seventeen marble workers and 18 healthy controls were studied. In all subjects, NMTRs were measured by (99m)Tc-MAA rhinoscintigraphy. NMTRs of workers and control groups were compared by statistically. Mean NMTR was found as 9 ± 1.8 mm/min in marble workers whereas mean NMTR of healthy controls was 9.6 ± 2.2 mm/min. There was no statistically significant difference between NMTRs of workers and control groups (p > 0.05). This study has shown that occupationally exposured marble dusts may not cause functional impairment on NMTR in marble workshop workers.

To determine whether specific occupations and industries may be associated with sarcoidosis. A Case Control Etiologic Study of Sarcoidosis (ACCESS) obtained occupational and environmental histories on 706 newly diagnosed sarcoidosis cases and matched controls. We used Standard Industrial Classification (SIC) and Standard Occupational Classification (SOC) to assess occupational contributions to sarcoidosis risk. Univariable analysis identified elevated risk of sarcoidosis for workers with industrial organic dust exposures, especially in Caucasian workers. Workers for suppliers of building materials, hardware, and gardening materials were at an increased risk of sarcoidosis as were educators. Work providing childcare was negatively associated with sarcoidosis risk. Jobs with metal dust or metal fume exposures were negatively associated with sarcoidosis risk, especially in Caucasian workers. In this study, we found that exposures in particular occupational settings may contribute to sarcoidosis risk.

Incidence of non-Hodgkin's lymphoma in different employment categories was evaluated from the Swedish Cancer-Environment Registry, which links cancer incidence during 1961 to 1979 with occupational information from the 1960 census. New associations were found for men employed in shoemaking and shoe repair, porcelain and earthenware industries, education, and other white collar occupations. Several findings supported associations found in other countries, including excesses among woodworkers, furniture makers, electric power plant workers, farmers, dairy workers, lorry drivers, and other land transport workers. Risks were not increased among chemists, chemical or rubber manufacturing workers, or petrochemical refinery workers. Caution must be used in drawing causal inferences from these linked registry data because information on exposure and duration of employment is not available. Nevertheless, this study has suggested new clues to possible occupational determinants of non-Hodgkin's lymphoma. PMID:8431395

Objective: To investigate understand the current status of the sense of coherence and occupational stress in modern service workers, and to analyze the association between occupational stress and the sense of coherence. Methods: From March to April, 2016, 834 modern service workers from 3 companies in Shanghai, China (in air transportation industry, marketing industry, and travel industry) were surveyed by non-ran-dom sampling. The self-completion questionnaires were filled out anonymously given the informed consent of the workers. The occupational stress questionnaire was used to evaluate occupational stress, and the Chinese version of the Sense of Coherence Scale (SOC-13) was used to assess the mental health. Results: The mean score for the sense of coherence of the respondents was 61.54±10.46, and 50.1% of them were self-rated as having occupational stress. There were significant differences in SOC score between groups with different ages, marital status, positions, lengths of service, family per capita monthly income, and weekly work hours ( P <0.05). The occupational stress score differed significantly across groups with different marital status, lengths of service, and weekly work hours ( P <0.05). The scores for working autonomy, social support, and occupational stress differed significantly between groups with different SOC levels ( P< 0.05). There were significant differences in SOC score and the distribution of low-SOC respondents between groups with different levels of working autonomy, social support, and occupational stress. High SOC is a protective factor for occupational stress ( OR =0.39, 95% CI 0.26~ 0.59). Conclusion: Modern service workers in Shanghai have high SOC and moderate occupational stress. Therefore, improving SOC may reduce occupational stress.

Aflatoxins are a metabolite of Aspergillus molds and are widespread in the natural environment. Workers who handle food grains are at increased risk of exposure to aflatoxins and subsequently certain respiratory conditions. In India, more than half of the employed population is engaged in some type of agricultural work, yet little known about the respiratory problems as a result of exposure to aflatoxins among workers who handle food grains in India. The aim of this study was to determine the risk of occupational exposure to aflatoxins in food-grain workers compared to workers who are not occupationally exposed to food grains. Bronchoalveolar lavage (BAL) and serum samples from 46 food-grain workers and 44 non-food-grain workers were analyzed for the presence of aflatoxins. Microscopy and culture of BAL samples were performed to detect Aspergillus species. Aflatoxins were detected in 32·6% of the food-grain workers and 9·1% of non food grain workers (P<0·01). A significant difference was also found in BAL culture for Aspergillus (P<0·01) between the two groups. About 47·8% of the food-grain workers and 11·4% of non-food-grain workers had chronic respiratory symptoms. Occupational exposure to aflatoxins in food-grain workers was found to be associated with the increased presence of respiratory symptoms.

Statistics on occupational accidents provided by the Italian Institute for Occupational Diseases and Accidents (INAIL, Italian acronym) include only events that occurred in workers with regular employment status. The aim of the study was to establish a procedure in order to estimate the rate of occupational accidents in non-European-Union (non-EU) workers with irregular employment status and/or irregular immigrant status. The sources of data were the clinical records of the Emergency Department of San Bonifacio Hospital, and the population data of District 4 of Local Health Authority 20 of Verona, which was considered the catchment area of this hospital. Among 419 cases of accidents occurred in the numerator of the rate. The denominator of the rate was estimated by calculating: (1) the subjects of working age resident in District 4 (= 83714); (2) the total number of non-EU workers, assuming that the percentage was similar to that in San Bonifacio Municipality (= 0.115); the number of irregular non-EU workers, assuming that the percentage was similar to that in north-eastern Italy (= 0.103). Non-EU workers with irregular employment status and/or irregular immigrant status should, according to these calculations, be 992 (= 83714 x 0.115 x 0.103). The rate--147.2 (= 146/992) occupational accidents per 1000 irregular non-EU workers--is more than twice as high as that calculated in 2004 in Italy in regular non-EU workers (approximately 65 accidents per 1000). The difference can be explained by the fact that irregular workers find employment mainly in agriculture, building and the metallurgic industry, which have a high frequency of accidents, and are more willing to accept risky work and longer work shifts. On the assumption that the rate of occupational accidents in the 500,000 irregular workers living in Italy in 2004 was 147.2 per 1000 (as in the catchment area of the San Bonifacio Hospital), the number of accidents would be 73,600, against the 116,000 that occurred among regular non-EU workers in 2004 according to INAIL. Official INAIL statistics on occupational accidents therefore show a considerable underestimation.

Identify the cardiovascular risk factors in a group of workers in the province of Salamanca, protected by external prevention services, as regards exposure to occupational carcinogens, by sector of activity and gender. An observational descriptive epidemiological study was conducted. The sample selection was by stratified random sampling in each entity. The variables collected by questionnaire were, sociodemographic characteristics, exposure to occupational carcinogens, and cardiovascular risk factors (smoking, hypertension, dyslipidemia, and diabetes), using the clinical-work histories as a source of information. Statistically significant differences were observed in cardiovascular risk according to the exposure to occupational carcinogens (p <0.001), primarily among workers in the industry sector. A total of 32% of the workers in the province of Salamanca was exposed to some occupational carcinogen. Women were more exposed in the service sector and men in the agriculture and livestock sector. Nearly one third of the workers belonging to the external prevention services of the province of Salamanca, were exposed to some kind of occupational carcinogens. The most frequent being biological risks, solvent products, and silica, which were above the national mean of exposure. It is important to consider the exposure to occupational carcinogens in the implementation of interventions in the prevention of cardiovascular risk in the work place.

The fast growth of non-standard employment in developed countries highlights the importance of studying the influence of contract type on worker's safety and health. The main purpose of our study is to investigate whether non-standard workers are more injured than standard workers or not. Additionally, other risk factors for occupational accidents are investigated. Data from the Belgian surveys on work ability in 2009 and 2011 are used. During their annual occupational health examination, workers were asked to fill in a self-administered questionnaire. In total, 1886 complete responses are collected and analyzed using logistic regression. Temporary workers did not have higher injury rates than permanent workers [OR 0.5, 95% confidence interval 0.2-1.2]. Low-educated, less-experienced workers and those exposed to dangerous conditions are more frequent victims of occupational accidents. The present data do not support the hypothesis that non-standard workers have more injuries than standard workers. Our results about occupational accidents derived from a non-representative sample of the Belgian workforce and cannot be generalized due to the heterogeneity in job organization and labor regulations between countries. Further research is needed to extend our findings and to seek other factors that may be associated with work accidents.

To investigate possible associations between occupation and hospitalization for systemic lupus erythematosus (SLE) in a nationwide study. A nationwide database was constructed in Sweden by linking the Swedish Census to the Hospital Discharge Register to obtain data on all first hospitalizations with a primary or secondary diagnosis of SLE in adults during the study period (1970 to 2008). Standardized incidence ratios (SIR) and 95% CI were calculated for different occupations. Two cohorts were defined based on occupational titles recorded in Swedish census data in 1970 and 1980. A total of 8921 male and 42290 female hospitalizations for SLE were retrieved in individuals aged over 15 years. High education (> 12 yrs) was associated with a lower risk of hospitalization for SLE among both women (SIR = 0.73) and men (SIR = 0.72). Among men with the same occupation in 2 consecutive censuses, increased risks (SIR) > 2.0 were present among artistic workers (2.52); shop managers and assistants (3.63); miners and quarry workers (6.04); shoe and leather workers (6.93); plumbers (2.21); other construction workers (2.08); glass, ceramic and tile workers (4.43); chimney sweeps (4.54); and military personnel (3.01). Among women with the same occupation in 2 consecutive censuses, no occupation was associated with SIR > 2.0. Occupation may carry significantly increased risk of hospital admission for SLE. Especially among men, several occupations were associated with increased risks for SLE.

Objectives In China, there have been an increasing number of migrant workers from rural to urban areas, and migrant workers have the highest incidence of occupational diseases. However, few studies have examined the impact of occupational stress on job burnout in these migrant workers. This study aimed to investigate the relationship between occupational stress and job burnout among migrant workers. Design This study used a cross-sectional survey. Setting This investigation was conducted in Dongguan city, Guangdong Province, China. Participants 3806 migrant workers, aged 18–60 years, were randomly selected using multistage sampling procedures. Primary and secondary outcome measures Multistage sampling procedures were used to examine demographic characteristics, behaviour customs and job-related data. Hierarchical linear regression and logistic regression models were constructed to explore the relationship between occupational stress and burnout. Results Demographics, behaviour customs and job-related characteristics significantly affected on burnout. After adjusting for the control variable, a high level of emotional exhaustion was associated with high role overload, high role insufficiency, high role boundary, high physical environment, high psychological strain, high physical strain, low role ambiguity, low responsibility and low vocational strain. A high level of depersonalisation was associated with high role overload, high role ambiguity, high role boundary, high interpersonal strain, high recreation, low physical environment and low social support. A low level of personal accomplishment was associated with high role boundary, high role insufficiency, low responsibility, low social support, low physical environment, low self-care and low interpersonal strain. Compared to the personal resources, the job strain and personal strain were more likely to explain the burnout of rural-to-urban migrant workers in our study. Conclusions The migrant workers have increased job burnouts in relation to occupational stress. Relieving occupational stress and maintaining an appropriate quantity and quality of work could be important measures for preventing job burnout among these workers. PMID:27534989

OBJECTIVE: To locate sources of occupational exposure to nasal and bladder carcinogens for surveillance follow up in British Columbia, Canada. METHODS: Incident cases of nasal cancer (n = 48), bladder cancer (n = 105), and population based controls (n = 159) matched for sex and age, were interviewed about their jobs, exposures, and smoking histories. Odds ratios (ORs) were calculated for 57 occupational groups with stratified exact methods to control for age, sex, and smoking. RESULTS: Occupational groups at increased risk of nasal cancer included: textile workers (six cases, OR 7.6); miners, drillers, and blasters (six cases, OR 3.5); welders (two cases, OR 3.5); pulp and paper workers (three cases, OR 3.1); and plumbers and pipefitters (two cases, OR 3.0). Nasal cancer ORs were not increased in occupations exposed to wood dust, possibly due to low exposures in local wood industries. Strongly increased risks of bladder cancer were found for sheet metal workers (four cases, OR 5.3), miners (19 cases, OR 4.5), gardeners (six cases, OR 3.7), and hairdressers (three cases, OR 3.2). Among occupations originally considered at risk, the following had increased risks of bladder cancer: painters (four cases, OR 2.8); laundry workers (five cases, OR 2.3); chemical and petroleum workers (15 cases, OR 1.8); machinists (eight cases, OR 1.6); and textile workers (three cases, OR 1.5). CONCLUSIONS: Occupational groups with increased risks and three or more cases with similar duties were selected for surveillance follow up. For nasal cancer, these included textile workers (five were garment makers) and pulp and paper workers (three performed maintenance tasks likely to entail stainless steel welding). For bladder cancer, these included miners (12 worked underground), machinists (five worked in traditional machining), hairdressers (three had applied hair dyes), and laundry workers (three were drycleaners).

Speech recognition index of workers with tinnitus exposed to environmental or occupational noise: a comparative study

PubMed Central

2012-01-01

Introduction Tinnitus is considered the third worst symptom affecting humans. The aim of this article is to assess complaints by workers with tinnitus exposed to environmental and occupational noise. Methodology 495 workers went through an epidemiological survey at the Audiology Department of the Center for Studies on Workers’ Health and Human Ecology, from 2003 to 2007. The workers underwent tonal and vocal audiometry, preceded by a clinical and occupational history questionnaire. Two-factor ANOVA and Tukey were the statistical tests used. All the analysis set statistical significance at α=5%. Findings There was a higher prevalence of occupational tinnitus (73.7%), a predominance of female domestic workers (65.4%) in cases of environmental exposure, and predominance of male construction workers (71.5%) for occupational exposure. There was a significant difference in workers with hearing loss, who showed a mean speech recognition index (SRI) of 85%, as compared to healthy workers with a mean SRI greater than 93.5%. Signs and symptoms, speech perception, and interference in sound localization with the type of noise exposure (environmental versus occupational) comparisons found no significant differences. Conclusion Studied group’s high prevalence of tinnitus, major difficulties in speech recognition with hearing loss and the presence of individuals with normal hearing with both types of exposure justify the importance of measures in health promotion, prevention, and hearing surveillance. The findings highlight the importance of valuing the patients’ own perception as the first indication of tinnitus and hearing loss in order to help develop appropriate public policies within the Unified National Health System (SUS).

Occupational health programme for lead workers in battery plants

NASA Astrophysics Data System (ADS)

Lee, Byung-Kook

The realization of problems resulting from the exposure to undue high lead levels of workers in lead-using industries, particularly in storage battery plants, has given rise to a new occupational health service, the so-called type specific (harmful agent specific) group occupational health. In 1988, the Korean Ministry of Labor designated the Institute of Industrial Medicine, Soonchunhyang University, as an authorized organization to take care of lead workers in lead industries. The following occupational health services are provided by the Institute: (i) physical health examination; (ii) biological monitoring with zinc protoporphyrin, urine δ-aminolevulinic acid and blood lead; (iii) respiratory protection with maintenance-free respirators; (iv) measurement of the environmental condition of workplaces; (v) health education. A three-year occupational health programme for lead workers has contributed to improvements in the working conditions of lead industries, particularly in large-scale battery plants, and has decreased the unnecessary high lead burden of workers through on-going medical surveillance with biological monitoring and health education schemes. The strong commitment of both employers and the government to improve the working conditions of lead industries, together with the full cooperation of lead workers, has served to reduce the high lead burdens of lead workers. This decreases the number of lead-poisoning cases and provides more comfortable workplaces, particularly in battery plants.

Objective To estimate the prevalence of obesity and the change of prevalence of obesity between 2004–2007 and 2008–20011 by occupation among US workers in the National Health Interview Survey. Methods Self-reported weight and height were collected and used to assess obesity (body mass index ≥ 30 kg/m2). Gender-, race/ethnicity-, and occupation-specific prevalence of obesity were calculated. Results Prevalence of obesity steadily increased from 2004 through 2008 across gender and race/ethnicity but leveled off from 2008 through 2011. Non-Hispanic black female workers in health care support (49.2%) and transportation/material moving (46.6%) had the highest prevalence of obesity. Prevalence of obesity in relatively low-obesity (white-collar) occupations significantly increased between 2004–2007 and 2008–2011, whereas it did not change significantly in high-obesity (blue-collar) occupations. Conclusions Workers in all occupational categories are appropriate targets for health promotion and intervention programs to reduce obesity. PMID:24682108

Emergency Medical Services (EMS) workers are shift workers in a high-risk, uncontrolled occupational environment. EMS-worker fatigue has been associated with self-reported injury, but the influence of extended weekly work hours is unknown. A retrospective cohort study was designed using historical shift schedules and occupational injury and illness reports. Using multilevel models, we examined the association between weekly work hours, crew familiarity, and injury or illness. In total, 966,082 shifts and 950 reports across 14 EMS agencies were obtained over a 1-3 year period. Weekly work hours were not associated with occupational injury or illness. Schedule characteristics that yield decreased exposure to occupational hazards, such as part-time work and night work, conferred reduced risk of injury or illness. Extended weekly work hours were not associated with occupational injury or illness. Future work should focus on transient exposures and agency-level characteristics that may contribute to adverse work events. © 2015 Wiley Periodicals, Inc.

African Immigrants in Low-Wage Direct Health Care: Motivations, Job Satisfaction, and Occupational Mobility.

PubMed

Covington-Ward, Yolanda

2017-06-01

This study explores motivations, job satisfaction, and overall perceived occupational mobility for African immigrants working in low-wage direct health care occupations. The study uses qualitative semi-structured interviews with a sample of thirty African immigrant workers in the greater Pittsburgh metropolitan area. Results show that four major themes captured the motivations of interviewees for doing direct care work: passion for care work, quick money, easily obtained employment, and direct care work as a pathway to other health occupations. The majority of the interviewees were satisfied with their jobs, yet almost all of them saw their occupations as temporary or transitional employment. Most of the interviewees also saw their jobs as lacking occupational mobility. In light of the increased national demand for direct care workers, the growing numbers of immigrants in the direct care labor force, and the high turnover and low retention rates of direct care workers overall, the study suggests that more must be done to make direct care work attractive and rewarding for African immigrant workers.

Working for citizenship: the dangers of occupational deprivation.

PubMed

Hocking, Clare

2012-01-01

To examine published case examples of occupational deprivation in relation to Wilcock's 1989 theoretical proposal that it is caused by economic and political systems, institutional policies, or advances in technology that displace workers. Eleven accounts of occupational deprivation centering on access to or maintenance of a work role. A thematic review of articles reporting access to or maintenance of a worker role as a major concern were located in an electronic search of multiple databases using the keyword `occupational deprivation'. While no examples pertaining to technological change were located, legislation enacted to protect national security or redress the ongoing affects of colonisation, a philosophy of punishing prisoners, and healthcare and employment structures were identified as causes of occupational deprivation. Economic and political systems and institutional policies are confirmed to cause occupational deprivation of worker roles in prison and indigenous populations, migrant workers and older female immigrants, young women displaced by war, refugees and asylum seekers, and people with disabilities. The ongoing economic burden of wasting human potential and the loss of cultural practices that support productive occupations are two negative outcomes.

The aim of this article is to reduce the risk of occupational hazards and improve safety conditions by enhancing hazard knowledge and identification as well as improving safety behavior for freight port enterprises. In the article, occupational hazards to health and their prevention measures of freight port enterprises have been summarized through a lot of occupational health evaluation work, experience and understanding. Workers of freight port enterprises confront an equally wide variety of chemical, physical and psychological hazards in production technology, production environment and the course of labor. Such health hazards have been identified, the risks evaluated, the dangers to health notified and effective prevention measures which should be put in place to ensure the health of the port workers summarized. There is still a long way to go for the freight port enterprises to prevent and control the occupational hazards. Except for occupational hazards and their prevention measures, other factors that influence the health of port workers should also be paid attention to, such as age, work history, gender, contraindication and even the occurrence and development rules of occupational hazards in current production conditions.

The present study examines gender differences in occupations, occupational hazards, and musculoskeletal symptoms in Korean workers. We performed a secondary analysis of data from the fourth Korean Working Conditions Survey (KWCS). Relative to "managers," men who were "craft and related trades workers," "equipment, machine operating and assembling workers," and in "elementary occupations" were more likely to report back pain (ORs: 2.08, 2.33, and 2.71, respectively); women who were "skilled agricultural, forestry, and fishery workers" were more likely to report back pain (OR: 3.96). Back pain was more likely to be reported in men exposed to "carrying/moving heavy loads," "painful/tiring postures," and "repetitive hand/arm movements" (ORs: 1.20, 2.26, and 1.28, respectively). Men and women workers differed in their reporting of ergonomic risk factors, and complaints of musculoskeletal symptoms. Am. J. Ind.

2016-08-01

Cambodia has developed booming textile, garment, tourism, and entertainment service industries since the mid-1990s. The 2007 global financial crisis pushed many garment workers, who lost their jobs, into the entertainment sector. Entertainment workers are typically engaged informally by their employers and are subjected to long working hours, sexual harassment, and violence. Many who sell beverages are forced into excessive alcohol consumption as part of their work. Many are also expected by their employers and clients to provide sexual services. To address unsafe and unhealthy working conditions for these workers, an innovative occupational safety and health regulation was adopted in 2014. This first-of-its-kind occupational safety and health regulation was developed jointly by the Cambodian Ministry of Labour and Vocational Training and employers' and workers' organizations in the entertainment sector. The implementation of this regulation can also be a viable contribution of occupational safety and health to HIV interventions for these workers. © The Author(s) 2016.

Objective: To investigate occupational stress in assembly line workers in electronics manu-facturing service (EMS) and related influencing factors. Methods: From June to October, 2015, a cross-sectional survey was performed for 5 944 assembly line workers in EMS (observation group) and 6 270 workers from other posts (non-assembly line workers and management personnel; control group) using the self-made questionnaire for basic information, job demand-control (JDC) model questionnaire, and effort-reward imbalance (ERI) model questionnaire to collect respondents' basic information and occupational stress. Results: The observation group had significantly lower work autonomy, social support, and work reward scores than the control group (2.72 ± 0.63/3.64 ± 0.68/4.06 ± 0.80 vs 3.00 ± 0.67/3.83 ± 0.68/4.24 ± 0.75, t =23.53, 15.41, and 12.70, all P <0.05) , as well as significantly higher work effort and job involvement scores than the control group (2.34±0.78/2.48±0.78 vs 2.21±0.80/2.33±0.77, t =-9.08 and-10.90, both P <0.05). The observation group had significantly higher proportions of workers with occupational stress determined by JDC and ERI models than the control group (64.5%/12.7% vs 52.6%/9.9%, χ 2 =182.26 and 23.41, both P <0.05). Female sex, migrant workers, working time >60 hours/week, and sleeping time <7 hours/day were major risk factors for occupational stress in JDC model; education background of Bachelor's degree or above, working time >60 hours/week, and sleeping time<7 hours/day were major risk factors for occupational stress in ERI model, while female sex and a high monthly income reduced the risk of occupational stress in ERI model. Conclusion: Assembly line workers in EMS are a relatively vulnerable group and have a high degree of occupational stress. Working time >60 hours/week and sleeping time <7 hours/day are major risk factors for occupational stress.

Stomach cancer and occupation in Sweden: 1971–89

Aragones, N; Pollan, M; Gustavsson, P

2002-01-01

Objectives: To examine the relation between gastric cancer and occupation among men and women gainfully employed in 1970 in Sweden for the period 1971–89 and, more specifically, to evaluate whether any excess of incidence of gastric cancer had also occurred among the subcohort of people reporting the same occupation in 1960 and 1970. Methods: In both sexes and cohorts, relative risks adjusted for age, period of diagnosis, and geographical risk area were computed for occupational codes specified at one, two, or three level (occupational sector, occupational group, and occupation, respectively). Relative risks were calculated with all other occupations as reference and then, to take socioeconomic status into account, solely other occupations within the same occupational sector were used. Results: Among men, occupations with increased risk included miners and quarrymen, construction and metal processing workers, supporting the possible causative role of dusty environments in stomach cancer. In men, the results also provide support for increased risks among electrical and mechanical engineers, fishermen, petrol station workers, motor vehicle drivers, butchers and meat preparers, dockers, freight handlers, launderers and dry cleaners. Furthermore, it is worth noting interesting results for women, whose occupational risks have been studied less. Excess risks were found for practical nurses, cashiers, bank employees, engineering and electronic industry workers, food industry, housekeeping and cleaning workers. Due to the many occupations studied, several significant associations may be expected by chance. Conclusions: The study is explorative but provides support for the relations suggested previously between occupational exposure to dusty environments and stomach cancer, together with some new high risk occupations which should be further studied.

The age-adjusted incidence of cutaneous squamous cell carcinoma (cSCC) in the Nordic countries has increased during the last 60 years, and the identification of occupational variation in the relative risk of cSCC may have preventive implications. We sought to describe variation in the relative risk of cSCC between occupational categories in Finland, Iceland, Norway, and Sweden. This is a historical prospective cohort study based on record linkages between census data for 12.9 million people and cancer registry data from 1961 to 2005. Standardized incidence ratios for cSCC were estimated for 53 occupational categories with the cSCC incidence rates for the national population of each country used as reference. During follow-up, 87,619 incident cases of cSCC were reported to the national cancer registries. In all countries combined, significant increased standardized incidence ratios were observed among seamen, military personnel, public safety workers, technical workers, teachers, transport workers, physicians, dentists, nurses, other health workers, religious workers, clerical workers, administrators, and sale agents (standardized incidence ratios between 1.08 and 1.77). Information on occupation was based on 1 point in time only. The occupational variation of the relative risk of cSCC might be associated with socioeconomic factors, and to some extent to occupational exposures.

2004-03-01

An industry producing rotor blades for wind turbines with an epoxy-based technology had experienced an increasing number of workers with dermatitis, among whom the frequency of occupational contact allergy (OCA) was suspected to be underestimated. To investigate the frequency of OCA by patch-testing with a specially profiled occupational patch test series. 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 an occupational patch test series and the European Standard patch test series. Of the 603 investigated workers, 10.9% had OCA and 5.6% had contact allergy to epoxy resin in the standard test series. Contact allergy to amine hardeners/catalysts was found in 4.1% of the workers. Among the workers with OCA, 48.5% reacted to work material other than epoxy resin in the European Standard patch test series. Approximately 50% of the workers with OCA would not have been detected if only the European Standard patch test series had been used.

The present study aimed to identify the perceptions of gas station workers about physical, chemical, biological and physiological risk factors to which they are exposed in their work environment; identify types of occupational accidents involving gas station workers and; report the development of a socioenvironmental intervention as a tool for risk communication to gas station workers. A quantitative study was performed with 221 gas station workers in southern Brazil between October and December 2010. Data collection was performed between October to December 2010 via structured interviews. The data were analyzed using SPSS 19.0. The participants identified the following risk types: chemical (93.7%), physical (88.2%), physiological (64.3%) and biological (62.4%). In this sample, 94.1% of gas station workers reported occupational accidents, and 74.2% reported fuel contact with the eyes (p < 0.05). It is concluded that workers perceive risks, and that they tend to relate risks with the occurrence of occupational accidents as an indicator of the dangerous nature of their work environment.

This study estimates and compares the prevalence of select physical and chemical exposures among green versus non-green U.S. workers. Methods Data from the U.S. 2010 National Health Interview Survey(NHIS) Occupational Health Supplement were linked to the Occupational Information Network(O*NET) Database. We examined four main exposures:1)vapors, gas, dust, fumes(VGDF);2)secondhand tobacco smoke;3)skin hazards;4)outdoor work. Results Green collar workers were significantly more likely to report exposure to VGDF and outdoor work than non-green collar workers(Adjusted Odds Ratio[AOR]=1.25; 95% CI=1.11–1.40; AOR=1.44(1.26–1.63), respectively). Green collar workers were less likely to be exposed to chemicals(AOR=0.80; 0.69–0.92). Conclusions Green collar workers appear to be at greater risk for select workplace exposures. As the green industry continues to grow, it is important to identify these occupational hazards in order to maximize worker health. PMID:28490043

Is social class standardisation appropriate in occupational studies?

PubMed Central

Brisson, C; Loomis, D; Pearce, N

1987-01-01

Social class standardisation has been proposed as a method for separating the effects of occupation and "social" or "lifestyle" factors in epidemiological studies, by comparing workers in a particular occupation with other workers in the same social class. The validity of this method rests upon two assumptions: (1) that social factors have the same effect in all occupational groups in the same social class, and (2) that other workers in the same social class as the workers being studied are free of occupational risk factors for the disease of interest. These assumptions will not always be satisfied. In particular, the effect of occupation will be underestimated when the comparison group also has job-related exposures which cause the disease under study. Thus, although adjustment for social class may minimise bias due to social factors, it may introduce bias due to unmeasured occupational factors. This difficulty may be magnified when occupational category is used as the measure of social class. Because of this potential bias, adjustment for social class should be done only after careful consideration of the exposures and disease involved and should be based on an appropriate definition of social class. Both crude and standardised results should be presented when such adjustments are made. PMID:3455422

To investigate the influence of several personal and occupational characteristics on the occurrence of occupation injuries, expressed in different categories (minor, serious, fatal and overall) by applying tools that are widely used in economic analyses. Panel data were used to estimate occupational injuries in an aggregate manner: both by regions and occupational categories and by industries and occupational categories. Data on occupational injuries were drawn from the Ministry of Labor and Social Affairs while the remaining information was drawn from the Workforce Population Survey for all quarters from 1999 to 2002. Permanent workers, male workers, public sector employees and those with secondary education or who had received on-the-job training were safer at their workplaces. Male and foreign workers were at greater risk of occupational injuries. The risk of serious or fatal accidents was reduced by greater work experience and was increased by working longer hours. Prevention would help to reduce the risk of accidents in temporary, male, private-sector and foreign workers. To reduce the incidence of serious and fatal accidents, the number of hours worked should be limited, especially in employees without extensive work experience.

Most emerging infectious diseases are zoonotic in origin, with wildlife a frequent source of zoonotic disease events. Although individuals with extensive wildlife contact may be at the greatest risk of contracting novel infectious agents, the occupational risk of those working closely with wildlife has not been well studied. This study assessed the occupational exposures among wildlife health professionals working in multiple countries worldwide. An occupational risk survey of past and present exposures was developed and administered online in a confidential manner to wildlife workers recruited through an ongoing international wildlife pathogen surveillance project. Surveys were completed by 71 participants in 14 countries. Significant lifetime exposures reported included bites from bats and rodents and touching dead animals. Completion of training in occupational safety was reported by 75% of respondents. While gloves were used for most tasks, use of N95 respirators and other personal protective equipment varied by task. Eighty percent of workers reported rabies vaccination. Some respondents indicated interest in enhanced occupational health services targeting their unique needs. Wildlife workers represent an occupational population at risk of zoonotic infection and injury. Enhanced occupational health services targeting wildlife workers could reduce the risk and sequelae of zoonotic exposure and infection.

Depression and post-traumatic stress disorder frequently occur as a consequence of occupational accidents. To date, research has been primarily focused on high-risk workers, such as police officers or firefighters, and has rarely considered individuals whose occupational environment involves the risk of severe, but not necessarily life-threatening, injury. Therefore, the present study was aimed at assessing the psychological consequences of accidents occurring in several occupational settings (e.g., construction and industry). Thirty-eight victims of occupational accidents (injured workers) and 38 gender-, age-, and years of education-matched workers who never experienced a work accident (control group) were recruited. All participants underwent a semi-structured interview administered by a trained psychologist, and then were requested to fill in the questionnaires. Injured workers reported more severe anxious, post-traumatic and depressive symptoms, and poorer coping skills, as compared to controls. In the injured group low levels of resilience predicted post-traumatic symptomatology, whereas the degree of physical injury and the length of time since the accident did not play a predictive role. The results suggest that occupational accidents may result in a disabling psychopathological condition, and that a brief psychological evaluation should be included in the assessment of seriously injured workers.

The purpose of the present study was to identify the association between presenteeism and long working hours, shiftwork, and occupational stress using representative national survey data on Korean workers. We analyzed data from the second Korean Working Conditions Survey (KWCS), which was conducted in 2010, in which a total of 6,220 wage workers were analyzed. The study population included the economically active population aged above 15 years, and living in the Republic of Korea. We used the chi-squared test and multivariate logistic regression to test the statistical association between presenteeism and working hours, shiftwork, and occupational stress. Approximately 19% of the workers experienced presenteeism during the previous 12 months. Women had higher rates of presenteeism than men. We found a statistically significant dose-response relationship between working hours and presenteeism. Shift workers had a slightly higher rate of presenteeism than non-shift workers, but the difference was not statistically significant. Occupational stress, such as high job demand, lack of rewards, and inadequate social support, had a significant association with presenteeism. The present study suggests that long working hours and occupational stress are significantly related to presenteeism.

Background Physical and mental health of workers is threatened due to various events and chronic occupational stress. This study was conducted to investigate the relationship between occupational stress and gastric disease in male workers of the shipbuilding industry. Methods Occupational stress measured among a total of 498 workers of a shipbuilding firm who visited the hospital for health examination using the Korean Occupational Stress Scale (KOSS)-short form, and the relationship between sociodemographic factors, health-related behaviors, occupational stress, and gastric disease, and the distribution of occupational stress by sociodemographic factors in the gastric disease group was examined. Results There was no significant association between gastric disease and total occupational stress score and its seven sub-factors. The analysis showed that risk of gastric disease was significantly higher in the Q1 group in which the stress caused by occupational discomfort among seven sub-factors was lowest than that in the Q4 group (odds ratio, 2.819; 95% confidence interval, 1.151 to 6.908). Analysis only on the gastric disease group showed that the stress score of laborers was higher in the four sub-factors than that of office workers (P < 0.05). Analysis on educational background showed that the scores of the three sub-factors were lower in subjects who's highest level of education was high school (P < 0.01). Conclusion This study suggests that it is necessary to improve the culture of Korean collectivism in the workplace and to manage the occupational stress in the low-educated and laborers. It is recommended for future studies to confirm the causal relationship between occupational stress and gastric disease by large scale studies using a KOSS which appropriately reflects workplace culture.

Few studies have investigated the occupational hazards of municipal solid waste workers, particularly in developing countries. Resultantly these workers are currently exposed to unknown and unabated occupational hazards that may endanger their health. We determined municipal solid waste workers' work related hazards and associated adverse health endpoints. A multifaceted approach was utilised comprising bioaerosols sampling, occupational noise, thermal conditions measurement, and field based waste compositional analysis. Results from our current study showed highest exposure concentrations for Gram-negative bacteria (6.8 × 103 cfu/m3) and fungi (12.8 × 103 cfu/m3), in the truck cabins. Significant proportions of toxic, infectious, and surgical waste were observed. Conclusively, municipal solid waste workers are exposed to diverse work related risks requiring urgent sound interventions. A framework for assessing occupational risks of these workers must prioritize performance of exposure assessment with regard to the physical, biological, and chemical hazards of the job.

Large numbers of workers worldwide work informally. Yet the discipline and practice of occupational health and safety covers largely only formal workers, in formal work places. A comprehensive approach would have to take into account specific hazards faced by those in different occupations, working in "atypical" work places. Local authorities exert significant influence in the provision of infrastructure that impacts on health and safety, such as water and sanitation. Examples from Brazil and Ghana show that positive interventions are possible so long as informal workers are recognized as contributing to the economy. A more inclusive occupational health and safety is most likely to happen in contexts where informal workers have an organized voice and where there are responsive health and safety personnel who understand that the world of work has changed. Some policy interventions that impact on healthy and safe work will need to involve multiple stakeholders and institutions. © The Author(s) 2016.

Occupational statements on death certificates of 2,457 males aged 25-64 who died from bladder cancer in selected coastal and estaurine regions of England and Wales during 1965-1980 were studied. Excess mortality was found for deck and engine room crew of ships, railway workers, electrical and electronic workers, shoemakers and repairers, and tobacco workers. An excess of cases also occurred among food workers, particularly those employed in the bread and flour confectionary industry or involved in the extraction of animal and vegetable oils and fats. Use of a job-exposure matrix revealed elevated risk for occupations in which most workers were exposed to paints and pigments, benzene and cutting oils. PMID:1520596

2005-09-01

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.

As health care provision in the United States shifts to primary care settings, it is vital that new models of occupational health services be developed that link clinical care to prevention. The model program described in this paper was developed at the Union Health Center (UHC), a comprehensive health care center supported by the International Ladies Garment Workers Union (now the Union of Needletrades, Industrial and Textile Employees) serving a population of approximately 50,000 primarily minority, female garment workers in New York City. The objective of this paper is to describe a model occupational medicine program in a union-based comprehensive health center linking accessible clinical care with primary and secondary disease prevention efforts. To assess the presence of symptoms suggestive of occupational disease, a health status questionnaire was administered to female workers attending the UHC for routine health maintenance. Based on the results of this survey, an occupational medicine clinic was developed that integrated direct clinical care with worker and employer education and workplace hazard abatement. To assess the success of this new approach, selected cases of sentinel health events were tracked and a chart review was conducted after 3 years of clinic operation. Prior to initiation of the occupational medicine clinic, 64% (648) of the workers surveyed reported symptoms indicative of occupational illnesses. However, only 42 (4%) reported having been told by a physician that they had an occupational illness and only 4 (.4%) reported having field a workers' compensation claim for an occupational disease. In the occupational medicine clinic established at the UHC, a health and safety specialist acts as a case manager, coordinating worker and employer education as well as workplace hazard abatement focused on disease prevention, ensuring that every case of occupational disease is treated as a potential sentinel health event. As examples of the success of this approach, index cases of rotator cuff tendonitis, lead poisoning, and formaldehyde overexposure in three patients and their preventative workplace follow-up, affecting approximately 150 workers at three worksites, are described. Work-related conditions diagnosed during the first 3 years of clinic operation included cumulative trauma disorders (141 cases), carpal tunnel syndrome (47 cases), low back disorders (33 cases), lead poisoning (20 cases), and respiratory disease (9 cases). This pilot project represents a new model for effective integration of clinical care and occupational disease prevention efforts within a primary care center. It could serve as a prototype for development of such services in other managed and primary care settings.

The contribution of occupation to health inequality

Health is distributed unequally by occupation. Workers on a lower rung of the occupational ladder report worse health, have a higher probability of disability and die earlier than workers higher up the occupational hierarchy. Using a theoretical framework that unveils some of the potential mechanisms underlying these disparities, three core insights emerge: (i) there is selection into occupation on the basis of initial wealth, education, and health, (ii) there will be behavioural responses to adverse working conditions, which can have compensating or reinforcing effects on health, and (iii) workplace conditions increase health inequalities if workers with initially low socioeconomic status choose harmful occupations and don’t offset detrimental health effects. We provide empirical illustrations of these insights using data for the Netherlands and assess the evidence available in the economics literature. PMID:24899789

This study compares health and occupational outcomes following a work-related injury for nonstandard and day-shift workers. National Population Health Survey data were used to explore outcomes 2 years post-work injury. Retrospective-matched cohort analyses examined main effects and interactions of shift schedule and work injury with changes in health, shift schedule, and labor force status. Models were adjusted for respondent characteristics, baseline health status, and occupational strength requirements. Injured nonstandard shift workers reported lower health utility index scores, compared with uninjured and injured daytime workers and uninjured nonstandard-shift workers. No significant interactions between shift and injury were found with schedule change and leaving the labor force. Injured nonstandard-shift workers are as likely to remain employed as other groups, but may be vulnerable in terms of diminished health.

To (1) compare occupational sitting between different socio-demographic, health-related, work-related and psychosocial categories, (2) identity socio-demographic, health-related, work-related and psychosocial correlates of occupational sitting, and (3) examine the moderating effect of work-related factors in the relation between correlates and occupational sitting. Randomly-selected Australian adults completed a web-based survey assessing socio-demographic (country of birth, gender, age, education, income), health-related (general health, weight, physical activity), work-related (employment status, occupational task, occupational classification) and sedentary-specific psychosocial (social norm, social support, self-efficacy, control, advantages, disadvantage, intention) factors, and occupational sitting-time. t-tests, ANOVAs and multiple linear regression analyses were conducted (in 2013) on a sample of employees (n=993). Respondents sat on average for 3.75 (SD=2.45) h/day during work. Investigated correlates explained 41% of the variance in occupational sitting. More occupational sitting was associated with being male, being younger, higher education and income, part-time and full-time employment, sedentary job tasks, white-collar/professional occupations, higher BMI, and perceiving more advantages of sitting less at work. Employment status and occupational classification moderated the association between control to sit less and occupational sitting. A lack of control to sit less was associated with higher occupational sitting in part-time and full-time workers, but not in casual workers; and in white-collar and professional workers, but not in blue-collar workers. Most important contributors to occupational sitting were work-related and socio-demographic correlates. More research is needed to confirm present results. Copyright © 2014 Elsevier Inc.

Study objective: Occupational structure represents the unequal geographical distribution of more desirable jobs among communities (for example, white collar jobs). This study examines joint effects of social class, race, and county occupational structure on coronary mortality rates for men, ages 35–64 years, 1988–92, in upstate New York. Design: Upstate New York's 57 counties were classified into three occupational structure categories; counties with the lowest percentages of the labour force in managerial, professional, and technical occupations were classified in category I, counties with the highest percentages were in category III. Age adjusted coronary heart disease (CHD) mortality rates, 35–64 years, (from vital statistics and census data) were calculated for each occupational structure category. Main results: An inverse association between CHD mortality and occupational structure was observed among blue collar and white collar workers, among black men and white men, with the lowest CHD mortality observed among white collar, white men in category III (135/100 000). About two times higher mortality was observed among blue collar than white collar workers. Among blue collar workers, mortality was 1.3–1.8 times higher among black compared with white workers, and the highest rates were observed among black, blue collar workers (689/100 000). Also, high residential race segregation was shown in all areas. Conclusions: Results suggest the importance of community conditions in coronary health of local populations; however, differential impact on subpopulations was shown. Blue collar and black workers may especially lack economic and other resources to use available community services and/or may experience worse working and living conditions compared with white collar and white workers in the same communities.

The Fukushima Daiichi Nuclear Power Plant (NPP) 1 was severely damaged from the chain reaction of the Great East Japan Earthquake and Tsunami on 11 March 2011, and the consequent meltdown and hydrogen gas explosions. This resulted in the worst nuclear accident since the Chernobyl accident of 1986. Just as in the case of Chernobyl, emergency workers were recruited to conduct a wide range of tasks, including disaster response, rescuing activities, NPP containment, and radiation decontamination. This paper describes the types and efficacy of the various occupational health interventions introduced to the Fukushima NPP radiation workers. Such interventions were implemented in order to prevent unnecessary radiation overexposure and associated adverse health effects and work injuries. Less than 1% of all emergency workers were exposed to external radiation of >100 mSv, and to date no deaths or health adversities from radiation have been reported for those workers. Several occupational health interventions were conducted, including setting of new regulatory exposure limits, improving workers' radiation dosimetry, administration of stable iodine, running an occupational health tracking system, and improving occupational medicine and preventative care. Those interventions were not only vital for preventing unnecessary radiation, but also for managing other general health issues such as mental health, heat illness and infectious diseases. Long-term administration of the aforementioned occupational health interventions is essential to ensure the ongoing support and care for these workers, who were put under one of the most severe occupational health risk conditions ever encountered. © The Author 2014.

2013-01-01

Objective To investigate the feasibility, costs and sample representativeness of a recruitment method that used workers with back injuries as the point of entry into diverse working environments. Methods Workers' compensation claims were used to randomly sample workers from five heavy industries and to recruit their employers for ergonomic assessments of the injured worker and up to 2 co-workers. Results The final study sample included 54 workers from the workers’ compensation registry and 72 co-workers. This sample of 126 workers was based on an initial random sample of 822 workers with a compensation claim, or a ratio of 1 recruited worker to approximately 7 sampled workers. The average recruitment cost was CND$262/injured worker and CND$240/participating worksite including co-workers. The sample was representative of the heavy industry workforce, and was successful in recruiting the self-employed (8.2%), workers from small employers (<20 workers, 38.7%), and workers from diverse working environments (49 worksites, 29 worksite types, and 51 occupations). Conclusions The recruitment rate was low but the cost per participant reasonable and the sample representative of workers in small worksites. Small worksites represent a significant portion of the workforce but are typically underrepresented in occupational research despite having distinct working conditions, exposures and health risks worthy of investigation.

Occupational and environmental exposures mostly represent complexmixture of genotoxic agents, however there is a wide variation in the specificity of biomarkers. Exploration of correlations among biomarkers contributes to the further progress of molecular cancer epidemiology and to the selection of the optimal biomarkers for the investigation of human exposure to carcinogens. The aim of this study was to assess the potential cytogenetic damage associated with occupational exposure to toxic agents among rubber industry workers by using Micronucleus (MN) assay. In the present study 35 occupationally exposed rubber industry workers and 30 controls were investigated for genetic damage. Both the exposed and control individuals were selected from rural areas of South India. Exfoliated Buccal cells were collected from the study population and examined for the presence of MN. Rubber industry workers showed a significant increase in micronucleated cells when compared to controls with respect to their smoking and drinking habits (P< 0.05). The present study suggested that occupational exposure to toxic chemicals in rubber industry can cause genetic damage. MN formation reflects genetic changes and/or events associated with carcinogenesis. Therefore the results of this study indicate that rubber industry workers may be at the risk of cancer. Therefore, it is important to take appropriate measures to protect the workers from occupational hazards.

Background The fast growth of non-standard employment in developed countries highlights the importance of studying the influence of contract type on worker’s safety and health. Objective The main purpose of our study is to investigate whether non-standard workers are more injured than standard workers or not. Additionally, other risk factors for occupational accidents are investigated. Methods Data from the Belgian surveys on work ability in 2009 and 2011 are used. During their annual occupational health examination, workers were asked to fill in a self-administered questionnaire. In total, 1886 complete responses are collected and analyzed using logistic regression. Results Temporary workers did not have higher injury rates than permanent workers [OR 0.5, 95% confidence interval 0.2–1.2]. Low-educated, less-experienced workers and those exposed to dangerous conditions are more frequent victims of occupational accidents. Conclusion The present data do not support the hypothesis that non-standard workers have more injuries than standard workers. Our results about occupational accidents derived from a non-representative sample of the Belgian workforce and cannot be generalized due to the heterogeneity in job organization and labor regulations between countries. Further research is needed to extend our findings and to seek other factors that may be associated with work accidents. PMID:27092408

Objectives: Occupational injuries remain an important unresolved issue in many of the developing and developed countries. We aimed to outline the causes, characteristics, measures and impact of occupational injuries among different ethnicities. Materials and Methods: We reviewed the literatures using PUBMED, MEDLINE, Google Scholar and EMBASE search engine using words: “Occupational injuries” and “workplace” between 1984 and 2014. Results: Incidence of fatal occupational injuries decreased over time in many countries. However, it increased in the migrant, foreign born and ethnic minority workers in certain high risk industries. Disproportionate representations of those groups in different industries resulted in wide range of fatality rates. Conclusions: Overrepresentation of migrant workers, foreign born and ethnic minorities in high risk and unskilled occupations warrants effective safety training programs and enforcement of laws to assure safe workplaces. The burden of occupational injuries at the individual and community levels urges the development and implementation of effective preventive programs. PMID:27051619

Electrical contact is a leading cause of occupational fatality in the construction industry. However, research on the factors that contribute to electricity-related fatality in construction is limited. To characterize, using an adapted Haddon's Matrix, the factors that contribute to electricity-related occupational fatalities in the construction industry in Ontario, Canada. Coroner's data on occupational electricity-related fatalities between 1997-2007 in the construction industry were acquired from the Ontario Ministry of Labour. Using an adapted Haddon's Matrix, we characterized worker, agent, and environmental characteristics of electricity-related occupational fatalities in the province through a narrative text analysis. Electrical contact was responsible for 15% of all occupational fatalities among construction workers in Ontario. Factors associated with said occupational fatalities included direct contact with electrical sources, lower voltage sources, and working outdoors. This study provides a profile of electricity-related occupational fatalities among construction workers in Ontario, and can be used to inform safety regulations.

Thousands of people die each year from cancer due to occupational causes. To reduce cancer in workers, preventive strategies should be used in the high-risk workplace. The effective prevention of occupational cancer requires knowledge of carcinogen agents. Like other areas of healthcare industry, occupational health has been affected by information technology solutions to improve prevention, early detection, treatment and finally the efficiency and cost effectiveness of the healthcare system. Information technology solutions are thus an important issue in the healthcare field. Information about occupational cancer in information systems is important for policy makers, managers, physicians, patients and researchers; because examples that include high quality data about occupational cancer patients and occupational cancer causes are able to determine the worker groups which require special attention. As a result exposed workers who are vulnerable can undergo screening and be considered for preventive interventions.

Occupational health nursing interventions to reduce third-party liability in workplace injuries.

PubMed

Delk, Kayla L

2012-03-01

This article explores general principles of workers' compensation law and the ability to sue third parties for employee injuries by using case law and the treatise Larson's Workers' Compensation Law. This overview provides occupational health nurses with a background on workers' compensation law, who is liable for employee injuries, and how recovery from third parties is distributed between the employer or insurer and the employee. The author then explores interventions that occupational health nurses can implement to reduce employee injury and employer costs for providing workers' compensation. The goal of this article is to stimulate occupational health nurses' critical-thinking and problem-solving skills so they may identify risks and implement cost-effective solutions that will prevent injuries to employees.

Canu, Irina Guseva; Ellis, Elizabeth Dupree; Tirmarche, Margot

2008-01-01

Workers involved in the nuclear fuel cycle have a potential for internal exposure to uranium. The present review of epidemiological studies of these workers aims to elucidate the relationship between occupational internal uranium exposure and cancer risk. Eighteen cohort and 5 nested case-control studies published since 1980 are reviewed. Workers occupationally exposed to uranium appear to be at increased risk of mortality from neoplasms of the lung, larynx, and lymphatic and haematopoietic tissue. Currently available evidence for a positive association between internal exposure to uranium and the risk of cancer is limited. The common weaknesses in reviewed studies include low statistical power and inaccurate assessment of internal exposure to uranium. Further investigations should focus on precise assessment of occupational exposure and address the issue of potential confounders.

High levels of youth employment, workplace hazards, and characteristics unique to adolescents contribute to a relatively high incidence of injuries among teens in the restaurant industry. This article discusses the ProSafety model of injury prevention among teen restaurant workers. Through integration with an existing career and technical education program, the ProSafety project seeks to prevent occupational injuries among the teen worker population through classroom safety education and internship skills reinforcement. ProSafety is the product of an innovative collaboration with occupational health nurses, business professionals, educators, and government. Its approach is derived from Social Cognitive Theory, is consistent with key values and strategies of occupational health nurses, and provides lessons for practitioners seeking to reduce occupational injuries in food service or among other populations of adolescent workers.

Skin disorders comprise more than 35% of all occupationally related diseases. 90-95% of work-related dermatoses are contact dermatitis. Effects of occupational dermatitis in the lives of workers are substantial. To plan any preventive program we need basic statistics of the problem, that we had no reliable one which includes a lot of industries in Iran. Therefore we decided to determine occupational contact dermatitis, and it's subtypes prevalence in various jobs. The objective of this study is determination of occupational contact dermatitis, and it's subtypes prevalence and comparison among various jobs. In this cross -sectional study, we examined 3061 workers of various industries during 2007-2012 and recognized contact dermatitis cases. Irritant and allergic cases were separated according to clinical judgment of physician and patch test using European standard series. We found 271 (prevalence=8.8%) occupational contact dermatitis cases which 247 (91.1%) were irritant, and the rest were allergic. The highest prevalence was in washing powder production and then glaze and paint workers, mechanists and chemical workers were located. There is a great variability for occupational contact dermatitis in various industries and between different countries. These statistics changes during the time by changing in number of workers and their characteristics, variation in material and process and glove use situation. So every country must have a national data bank of occupational contact dermatitis, which must be updated after a period of time.

The objective of this study was to compare occupational variation of the risk of bladder cancer in the Nordic countries and Canada. In the Nordic Occupational Cancer study (NOCCA), 73 653 bladder cancer cases were observed during follow-up of 141.6 million person-years. In the Canadian Census Health and Environment Cohort (CanCHEC), 8170 cases were observed during the follow-up of 36.7 million person-years. Standardised incidence ratios with 95% CI were estimated for 53 occupations in the NOCCA cohort and HR with 95% CIs were estimated for 42 occupations in the CanCHEC. Elevated risks of bladder cancer were observed among hairdressers, printers, sales workers, plumbers, painters, miners and laundry workers. Teachers and agricultural workers had reduced risk of bladder cancer in both cohorts. Chimney-sweeps, tobacco workers and waiters had about 1.5-fold risk in the Nordic countries; no risk estimates for these categories were given from the CanCHEC cohort. We observed different occupational patterns in risk of bladder cancer in Nordic countries and Canada. The only occupation with similarly increased risk was observed among sales workers. Differences in smoking across occupational groups may explain some, but not all, of this variation. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Postal delivery workers spend a large proportion of their work time outdoors, placing them at increased risk of skin cancer. To date, no studies have examined occupational sun safety knowledge and practice within this group in the UK. To describe the occupational sun safety knowledge and practice of UK postal delivery workers and to investigate the association of demographic, personal and occupational factors with knowledge and practice in order to identify potential strategies for improving sun safety in this occupational group. Postal delivery workers completed a questionnaire that collected data on occupational sun safety knowledge and practice in addition to demographic, personal and workplace characteristics. One-way analysis of variances were applied to assess differences in knowledge and practice by these characteristics. A total of 1153 postal delivery workers completed the questionnaire, a 60% response rate. Thirty-three per cent reported receiving sun safety training within the previous 12 months. The majority of respondents reported correct knowledge on three of the six domains and good practice on four of the six behavioural domains. However, only one-fifth of respondents reported wearing sunglasses and ensuring a plentiful intake of water. Knowledge and practice differed significantly according to demographic, personal and workplace characteristics. There is a need to raise the profile of occupational skin cancer in this occupational group and to increase the priority given to occupational sun safety policies alongside targeted and tailored interventions, the effect of which can be evaluated. © The Author 2015.

Smith, P M; Berecki-Gisolf, J

Interest in the relationship between age and serious work injury is increasing, given the ageing of the workforce in many industrialized economies. To examine if the relationship between age and risk of serious musculoskeletal injury differs when the physical demands of work are higher from those when they are lower. A secondary analysis of workers' compensation claims in the State of Victoria, Australia, combined with estimates of the insured labour force. We focused on musculoskeletal claims, which required 10 days of absence or health care expenditures beyond a pecuniary threshold. Regression models examined the relationship between age and claim-risk across workers with different occupational demands, as well as the relationship between occupational demands and musculoskeletal claim-risk across different age groups. Older age and greater physical demands at work were associated with an increased risk of musculoskeletal claims. In models stratified by occupational demands, we observed the relationship between age and claim-risk was steeper when occupational demands were higher. We also observed that the relationship between occupational demands and risk of work injury claim peaked among workers aged 25-44, attenuating among those aged 45 and older. This study's results suggest that although older workers and occupations with higher demands should be the targets of primary preventive efforts related to serious musculoskeletal injuries, there may also be gains in targeting middle-aged workers in the most physically demanding occupations. © The Author 2014.

Injury rate among mining workers in Zimbabwe was 789/1000 workers in 2008. The proportion of severe occupational injuries increased from 18% in 2008 to 37% in 2009. We investigated factors associated with severe injuries at the mine. An unmatched 1:1 case-control study was carried out at the mine, a case was any worker who suffered severe occupational injury at the mine and was treated at the mine or district hospital from January 2008 to April 2010, a control was any worker who did not suffer occupational injury during same period. We randomly selected 156 cases and 156 controls and used interviewer administered questionnaires to collect data from participants. Majority of cases, 155(99.4%) and of controls 142(91%) were male, 127(81.4%) of cases and 48(30.8%) of controls worked underground. Majority (73.1%) of severe occupational injuries occurred during night shift. Underground temperatures reached 500C. Factors independently associated with getting severe occupational injuries included working underground (AOR=10.55; CI 5.97-18.65), having targets per shift (AOR=12.60; CI 3.46-45.84), inadequate PPE (AOR=3.65 CI 1.34-9.89) and working more than 8 hours per shift (AOR=8.65 CI 2.99-25.02). Having targets exerts pressure to perform on workers. Prolonged working periods decrease workers' attention and concentration resulting in increased risk to severe injuries as workers become exhausted, lose focus and alertness. Underground work environment had environmental hazards so managers to install adequate ventilation and provide adequate PPE. Management agreed to standardize shifts to eight hours and workers in some departments have been supplied with adequate PPE.

Risk of occupational radiation-induced cataract in medical workers.

PubMed

Milacic, Snezana

ionizing radiation on the lens of the eye can produce a progressive cataract. Small cumulative doses, over a long time period, can produce adverse effects on the professional capabilities of health workers in the ionizing radiation zone. The aim of this study was to ascertain whether occupational exposure to low levels of ionizing radiation can cause an increase in prevalence of cataract. We compared a group with occupational cataract, consisting of 115 health workers in the ionizing radiation zone, and two control groups: a group of 100 health-care workers in the ionizing radiation zone, with a higher incidence of chromosomal aberrations, but without cataract; and another control group of 26 health-care workers with cataract, outside the zone; all risk factors for the development of cataract were considered: age, sex, diference in profession, duration of occupational exposure, years of service, level of blood sugar, blood pressure, arrhythmias, etc. A more significant incidence of cataract was found in workers in the ionizing radiation zone, where the relative risk was 4.6; p < 0.01. Radiology technicians showed the highest prevalence (63.5%), while physicians-radiologists and pneumologists were second (15.7%) and third (10.3%) respectively; nurses showed a 3.5% incidence and nuclear medicine department workers showed an incidence of only 1.7%. Other risk factors had an effect on the development of cataract (p < 0.05). Occupational exposure to low doses of ionizing radiation, together with other risk factors, is a significant cofactor in the occurrence of cataract as an occupational disease among x-ray exposed health care workers. The categories most at risk are radiology technicians,followed by radiologists.

Worker substance use, workplace problems and the risk of occupational injury: a matched case-control study.

This study examines the tendency toward problem behavior as an explanation for the relationship between problem substance use and occupational injury. The authors used a matched case-control study nested in a cohort of 26,413 workers, in which cases (n = 3,994) were workers suffering an occupational injury. Five controls per case (n = 19,970) were selected from the cohort of workers active on the day of the injury and matched on job type. Conditional logistic regression modeled the association of problem substance use with occupational injury, controlling for problem behaviors and worker characteristics. Problem substance use was indicated indirectly if any of the following were alcohol/drug-involved during the comparison period: Employee Assistance Program visit, excused absence or disciplinary action. Discipline records identified minor (absenteeism) and serious (dishonesty, theft, assault, harassment, disrespect) problem behaviors during the comparison period. The odds of injury among workers with an indicator of problem substance use was 1.35 (p = .015) times greater than the odds among workers without an indicator, controlling for job type and demographics as well as adjusting for exposure. This ratio declined to 1.21 (p = .138) when problem behaviors were also controlled for. Minor and serious problem behaviors were significantly associated with occupational injury (odds ratio [OR] = 1.73, p < .001, and OR = 2.19, p < .001, respectively), controlling for demographics and substance use. The relationship of problem substance use with occupational injury was weak when problem behaviors were controlled for, suggesting that this relationship, observed in previous studies, may be explained by a workers tendency toward problem behaviors. Workplace injury prevention programs should address the expression of problem behaviors as a complement to drug and alcohol deterrent programs.

To investigate the association of workplace occupational mental health (OMH) and related activities with psychological distress of workers in Japan. A total of 121 workplaces and their 3540 workers were surveyed using questionnaires assessing selected workplace OMH activities, demographic characteristics, psychological distress, and psychosocial work environment of the workers. A multilevel analysis was conducted. Promotion of communication correlated significantly and negatively with psychological distress among workers after adjusting for the covariates (P < 0.01). Occupational mental health activities correlated marginally significantly and negatively with psychological distress (P = 0.06). Their moderating effect for the worker-level association between psychosocial work environment and psychological distress was not significant. The findings suggest that promotion of communication in the workplace is associated with reduced psychological distress among workers. In addition, OMH activities may also be useful in reducing psychological distress.

Genetic testing in the workplace holds the promise of improving worker health but also raises ethical, legal, and social issues. In considering such testing, it is critical to understand the perspectives of workers, who are most directly affected by it, and occupational health professionals, who are often directly involved in its implementation. Therefore, a series of focus groups of unionized workers (n=25) and occupational medicine physicians (n=23) was conducted. The results demonstrated strikingly different perspectives of workers and physicians in several key areas, including the goals and appropriateness of genetic testing, and methods to minimize its risks. In general, workers were guided by a profound mistrust of the employer, physician, and government, while physicians were guided primarily by scientific and medical concerns, and, in many cases, by the business concerns distrusted by the workers.

Workers in blue-collar and service occupations smoke at higher rates than workers in white-collar and professional occupations. Occupational stress may explain some of the occupational class differences in smoking and quitting behavior. The purpose of this study is to investigate the contribution of occupational factors to smoking behavior over a ten year period among a multiethnic cohort of urban transit operators, while accounting for demographic factors and alcohol. The sample consists of 654 San Francisco Municipal Railway (MUNI) transit operators who participated in two occupational health studies and biennial medical examinations during 1983-85 and 1993-95. Workers who had initiated, increased, or maintained their smoking over the ten year period were compared to workers who remained non-smokers. Occupational factors included self-rated frequency of job problems (e.g., difficulties with equipment, passengers, traffic), job burnout (i.e., the emotional exhaustion subscale of the Maslach Burnout Inventory), time needed to unwind after work, and years employed as a transit operator. A series of logistic regression models were developed to estimate the contribution of occupational factors to smoking behavior over time. Approximately 35% of the workers increased, initiated, or maintained their smoking over the ten-year period. Frequency of job problems was significantly associated with likelihood of smoking increase, initiation, or maintenance (OR = 1.30; 95% CI 1.09, 1.55). Black operators were significantly more likely to have smoked over the ten-year period compared to operators in other racial/ethnic groups. Understanding the role of work-related stress vis-à-vis smoking behavior is of critical importance for crafting workplace smoking prevention and cessation interventions that are applicable to blue-collar work settings, and for developing policies that mitigate occupational stress.

To assess the temporal trends in occupation specific all causes and cause specific mortality in Japan between 1980 and 2005. Longitudinal analysis of individual death certificates by last occupation before death. Data on population by age and occupation were derived from the population census. Government records, Japan. Men aged 30-59. Age standardised mortality rate for all causes, all cancers, cerebrovascular disease, ischaemic heart disease, unintentional injuries, and suicide. Age standardised mortality rates for all causes and for the four leading causes of death (cancers, ischaemic heart disease, cerebrovascular disease, and unintentional injuries) steadily decreased from 1980 to 2005 among all occupations except for management and professional workers, for whom rates began to rise in the late 1990s (P<0.001). During the study period, the mortality rate was lowest in other occupations such as production/labour, clerical, and sales workers, although overall variability of the age standardised mortality rate across occupations widened. The rate for suicide rapidly increased since the late 1990s, with the greatest increase being among management and professional workers. Occupational patterns in cause specific mortality changed dramatically in Japan during the period of its economic stagnation and resulted in the reversal of occupational patterns in mortality that have been well established in western countries. A significant negative effect on the health of management and professional workers rather than clerks and blue collar workers could be because of increased job demands and more stressful work environments and could have eliminated or even reversed the health inequality across occupations that had existed previously.

Mental disorders in the workplace are a major public health problem. Knowledge of the impact of the psychosocial work environment on mental and behavioral disorders can assist occupational physicians in the identification and description of occupational risk situations, and help to define priority actions. However, no classification for occupational exposure factors is currently available. We aimed to build a thesaurus of "Organizational, Relational, Ethical and other Contributing Factors" (FOREC) linked with the onset of mental and behavioral disorders. The French Agency for Food, Environmental and Occupational Health and Safety (ANSES) initiated and supervised a multidisciplinary working group consisting of the representatives of the main French occupational and public health actors. All decisions were accepted on a consensus basis. This collaborative work led to the classification of occupational exposure factors for mental and behavioral disorders in the workplace. To test this thesaurus in clinical practice, a French multicenter study was implemented. Patients were workers referred to the Occupational Disease Centers for mental health issues at work. Factors contributing to mental and behavioral disorders among workers were identified and coded retrospectively from the worker's point of view using the FOREC thesaurus. We recruited 323 workers, aged 44.9±9.2 years, of which 31.3% were men. The most commonly encountered disorders were generalized anxiety disorders (106 workers, 32.8%) and moderate depressive episodes (86 workers, 26.7%). We identified 1357 factors, i.e. an average of 4.2 factors per worker. Among them, 575 (42.4%) were relational and 515 (37.9%) were organizational. All factors identified during consultations were described in the thesaurus. We built the first thesaurus of "Organizational, Relational, Ethical and other Contributing Factors" (FOREC) that may help to generate profiles of mental and behavioral disorders at work. Encoding and describing these exposure factors, as well as using a worldwide standardized and shared terminology, will help to identify specific workplace prevention programs.

Occupation could affect the distribution of smoking status of workers, and the success of smoking cessation among workers depends partly on worksite conditions. Blue collar workers have been identified as a high-risk group for smoking. The aim of the present study was to examine trends in smoking rates among urban civil servants in Japan according to occupational categories. Subjects were urban civil servants aged 30-59 years. They annually reported smoking status in a questionnaire in a worksite health check-up each year from 2004 to 2011. Urban civil servants reported substantially lower current smoking rates than national smoking rates in Japan (20.2%, 23.8%, and 27.0% for males in their 30s, 40s, and 50s and 2.4%, 6.3%, and 9.5% for females, respectively, in 2011). In analysis by occupational categories, current smoking rates declined among all groups except female white collar workers in their 50s. The current and persistent smoking rates (number of current smokers/[number of ex-smokers and current smokers]) among blue collar workers were higher than those among white collar workers at almost all time points in all age and gender groups. This study found relatively lower current smoking rates among urban civil servants than the national average and higher current and persistent smoking rates in blue collar workers than in white collar workers among them. These results would help to make suitable worksite smoking cessation policies for each occupational category.

Few studies have been aimed at describing organizational and psychosocial conditions of the Italian workforce by occupational group, and they have been mainly conducted within specific occupations. The present study aimed at identifying specific groups of occupations which have unfavourable profiles from the point of view of exposure to specific organizational factors and psychosocial risks, and to physical, chemical and ergonomic risks, and analyzing their distribution by worker age. The analysis was conducted on a sample of 4,195 workers in the Piedmont Region who were members of the CGIL Trade Union (Italian General Confederation of Labour), who answered a self-administered questionnaire in 2000, aimed at assessing chemical, physical, and ergonomic risks, accidents, and psychosocial factors connected with work organization and work tasks. Psychosocial risks were assessed via three scales aimed at measuring the degree of control, psychophysical demands, and worker satisfaction. The proportion of workers exposed to the above mentioned risks was analysed according to occupational group. This group was then compared with all other groups taken together, according to prevalence of high strain condition (combination of high demand and low control) and HSUR condition (High Strain Unfairly Rewarded; combination of high strain and low satisfaction). Among males aged 25-44 years, restricted to the occupation groups with more than ten workers in high strain condition, significantly higher proportions of stress were observed in leather workers and shoemakers, paper factory workers, rubber workers, crane and bridge crane operators, plastic workers, painters, transport drivers and carpenters. For many of these groups, excesses were confirmed for the HSUR condition. Among subjects aged over 44 years, a higher risk for high strain was confirmed in rubber workers, transport drivers and carpenters. In addition, machine tool operators, assembly line and mechanical workers in this age group were exposed to higher risk of stress. In younger women there was a significantly higher risk of both high strain and HSUR conditions in workers employed in the rubber, plastic and the food industries, and in machine tool workers. Such excess risk was confirmed in the latter three categories also among older women. In general, the proportion of male workers classified as working in high strain conditions decreased as age increased, while in women it remained stable. The study allowed evaluation of the differential impact of exposure to physical, chemical, and psychosocial risk factors among occupational groups, thus contributing to the identification and classification of exhausting jobs. The results further showed, particularly among men, a smaller proportion of older workers, compared to younger ones, exposed to harmful physical, chemical, ergonomic and psychosocial conditions, indicating a possible propensity of companies to adapt workplace conditions, organization and internal mobility to worker age.

Few data are available about the prevalence of occupational exposures to agents which can cause occupational asthma or aggravate preexisting asthma (asthmogens). Using potential occupational exposure data from the National Occupational Exposure Survey (NOES) of 1980-1983, we investigated the number of asthmogen exposures, asthmogen-exposure(s) per production worker, and unprotected occupational asthmogen exposures in different industries and occupations. Data for the entire United States were used to generate estimates of occupational exposure at two selected state and local levels. It was estimated that 7,864,000 workers in the surveyed industries were potentially exposed to one or more occupational asthmogen(s) in the United States. The average number of observed potential exposures per asthmogen-exposed worker was 4.4, and varied from 11.9, in the Water Transportation industry, to 1.2 in Local and Suburban transportation. The largest number of observed potential exposures was recorded in the Apparel and Other Finished Products (garment) industry. This work and further analyses using this approach are expected to contribute to a better understanding of the epidemiology of occupational asthma, and to serve as a guide to target future occupational asthma surveillance efforts.

Toxicology testing of fatally injured workers is not routinely conducted. We completed a case-series study of 2005–2009 occupational fatalities captured by Iowa’s Fatality Assessment and Control Evaluation (FACE) Program. The goals of our research were to: (1) measure the proportion of FACE cases that undergo toxicology testing, and describe the factors associated with being tested, and (2) measure the rate of positive toxicology tests, the substances identified and the demographics and occupations of victims who tested positive. Case documents and toxicology laboratory reports were reviewed. There were 427 occupational deaths from 2005 to 2009. Only 69% underwent toxicology testing. Younger workers had greater odds of being tested. Among occupational groups, workers in farming, fishing and forestry had half the odds of being tested compared to other occupational groups. Of the 280 cases with toxicology tests completed, 22% (n = 61) were found to have positive toxicology testing. Commonly identified drug classes included cannabinoids and alcohols. Based on the small number of positive tests, older victims (65+ years) tested positive more frequently than younger workers. Management, business, science, arts, service and sales/office workers had proportionately more positive toxicology tests (almost 30%) compared with other workers (18–22%). These results identify an area in need of further research efforts and a potential target for injury prevention strategies. PMID:24240727

Occupational asthma in maritime environments: an update.

2016-01-01

In 2006 we published our first review based on the available literature on occupational asthma in maritime environments in the "International Maritime Health" journal. Since then, we have obtained a great deal of new knowledge on asthma in seafood workers and fishermen and on the impact of exposures from sulphites preservatives, container fumigants etc. in maritime workers. This review aims to provide an update of the current knowledge base about occupational asthma in a maritime context and to provide recommendations regarding medical surveillance of workers at risk.

Danger and Dignity: Immigrant Day Laborers and Occupational Risk.

PubMed

Rathod, Jayesh M

2016-01-01

The plight of immigrant workers in the United States has captured significant scholarly attention in recent years. Despite the prevalence of discourses regarding this population, one set of issues has received relatively little attention: immigrant workers' exposure to unhealthy and unsafe working conditions, and their corresponding susceptibility to workplace injuries and illnesses. Researchers have consistently found that immigrant workers suffer disproportionately from occupational injuries and fatalities, even when controlling for industry and occupation. Why, then, are foreign-born workers at greater risk for workplace injuries and fatalities, when compared with their native-born counterparts? This Article seeks to develop answers to that question with the aid of empirical research and to build upon a growing interdisciplinary literature. This Article presents findings from a qualitative research study designed to explore the factors that shape occupational risks for immigrants. The study, conducted over several months in 2014, centered on in-depth interviews of eighty-four immigrant day laborers seeking employment in different parts of Northern Virginia. The workers' responses present a complex picture of the immigrant worker experience, reflecting persistent dangers alongside powerful expressions of worker dignity: while the Virginia day laborers continue to encounter significant occupational risks, many comfortably asserted their rights, complicating standard narratives of immigrant worker subordination and vulnerability. The results of the study also point to ongoing economic insecurities, and regulatory failures relating to the provision of training, use of protective equipment, and oversight of smaller worksites. The findings also signal the need for a more holistic approach to workplace regulation that concomitantly examines a range of workplace concerns, including wage violations, hostile work environments, and health and safety risks. Finally, the day laborers' experiences reveal that worker centers are well positioned to insulate immigrant workers from workplace risks, by promoting transparency and accountability in the employer-employee relationship.

Respiratory disease associated with occupational inhalation to hop (Humulus lupulus) during harvest and processing.

There is little published evidence for occupational respiratory disease caused by hop dust inhalation. In the United States, hops are commercially produced in the Pacific Northwest region. To describe occupational respiratory disease in hop workers. Washington State workers' compensation claims filed by hop workers for respiratory disease were systematically identified and reviewed. Incidence rates of respiratory disease in hop workers were compared with rates in field vegetable crop farm workers. Fifty-seven cases of respiratory disease associated with hop dust inhalation were reported from 1995 to 2011. Most cases (61%) were diagnosed by the attending health care practitioner as having work-related asthma. Seven percent of cases were diagnosed as chronic obstructive pulmonary disease, and the remaining cases were diagnosed as allergic respiratory disorders (eg, allergic rhinitis) or asthma-associated symptoms (eg, dyspnea). Cases were associated with hop harvesting, secondary hop processing, and indirect exposure. The incidence rate of respiratory disease in hop workers was 15 cases per 10,000 full-time workers, which was 30 times greater than the incidence rate for field vegetable crop workers. A strong temporal association between hop dust exposure and respiratory symptoms and a clear association between an increase in hop dust concentrations and the clinical onset of symptoms were apparent in 3 cases. Occupational exposure to hop dust is associated with respiratory disease. Respiratory disease rates were higher in hop workers than in a comparison group of agricultural workers. Additional research is needed before hop dust can be confirmed as a causative agent for occupational asthma. Copyright © 2014 American College of Allergy, Asthma & Immunology.

Torén, Kjell; Järvholm, Bengt

2014-05-01

The aim of the present study was to elucidate whether occupational exposure to vapors, gases, dusts, and fumes increases the mortality risk of COPD, especially among never smokers. The study population was a cohort of 354,718 male construction workers; of these, 196,329 were exposed to vapors, gases, dusts, and fumes, and 117,964 were unexposed. Exposure to inorganic dust, wood dust, vapors, fumes, gases, and irritants was based on a job-exposure matrix with a focus on exposure in the mid-1970s. The cohort was followed from 1971 to 2011. Relative risks (RRs) were obtained using Poisson regression models adjusting for age, BMI, and smoking habits. There were 1,085 deaths from COPD among the exposed workers, including 49 never smokers. Workers with any occupational exposure to vapors, gases, fumes, and dust showed an increased mortality due to COPD (RR, 1.32; 95% CI, 1.18-1.47). When comparing different exposure groups, there was a significantly increased mortality due to COPD among those exposed to fumes (RR, 1.20; 95% CI, 1.07-1.36) and inorganic dust (RR, 1.19; 95% CI ,1.07-1.33). Among never smokers, there was high mortality due to COPD among workers with any occupational airborne exposure (RR, 2.11; 95% CI, 1.17-3.83). The fraction of COPD attributable to occupational exposure was 0.24 among all workers and 0.53 among never-smoking workers. Occupational exposure to airborne pollution increases the mortality risk for COPD, especially among never smokers.

Through use of a nationally representative database, we examined the variability in both self-rated health and overall mortality risk within occupations across the National Occupational Research Agenda (NORA) Industry Sectors, as well as between the occupations within the NORA Industry sectors. Using multiple waves of the National Health Interview Survey (NHIS) representing an estimated 119,343,749 US workers per year from 1986 to 2004, age-adjusted self-rated health and overall mortality rates were examined by occupation and by NORA Industry Sector. There was considerable variability in the prevalence rate of age-adjusted self-rated poor/fair health and overall mortality rates for all US workers. The variability was greatest when examining these data by the Industry Sectors. In addition, we identified an overall pattern of increased poor/fair self-reported health and increased mortality rates concentrated among particular occupations and particular Industry Sectors. This study suggests that using occupational categories within and across Industry Sectors would improve the characterization of the health status and health disparities of many subpopulations of workers within these Industry Sectors.

Chatterjee, M

1993-02-01

The Self-Employed Workers' Association (SEWA) has conducted 4 longitudinal, community-based studies to survey the occupational health of self-employed women in Ahmedabad and Indore, India. It included the workers in all stages of research. SEWA staff examined women in readymade garment, bidi, agarbatti, and masala fields. Since SEWA did not use control groups, they could not establish cause and effect relationships. Masala workers had the highest illiteracy rate (66%). At least 50% of all workers (89% of readymade garment workers) worked 8-12 hours/day. Daily wages of most workers did not exceed Rs.10, confirming their low poverty level. The most common occupational health problem while working was pain in the limbs for bidi (63%) and readymade garment workers (80%). They also experienced back pain and headaches. After work, back pain was common among agarbatti (73%) and masala (39%) workers. Masala workers also suffered from blisters and calluses (51%) and burning sensation (45%), particularly in their hands. Gynecological problems (e.g., early periods, white discharge, and burning sensation while urinating) and abdominal pain were common in all 4 groups. These results demonstrated a need for further research on occupational health and gynecological diseases; health facilities to adjust services to meet self-employed workers needs; provision of safe and subsidized tools, safety equipment, benefits (e.g., sick leave and child care), and health insurance; and health education. SEWA recommends that self-employed workers receive identity cards, the government enforce minimum wage laws and regulate working hours, and workers are provided basic amenities (e.g., potable water and sanitation).

Occupational exposure to Mycobacterium tuberculosis. Legal issues in workers' compensation.

PubMed

Evenson, W

1999-08-01

Occupational exposure to TB remains a significant threat in select high risk occupations despite 5 years of declining disease incidence rates in the United States. TB kills more people on a global scale than any other infectious disease. One third of the global population is currently infected with TB. Workers' compensation insurance may be inadequate to cover lost wages and medical bills in cases of occupational exposure to TB if the source patient is unknown. There is a need to reform state laws for workers' compensation so TB infections in high risk employees are presumed to be work related unless a community exposure to the disease is identified.

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

Garcia, A M; Boix, P; Canosa, C

2004-03-01

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.

Occupational dental erosion from exposure to acids: a review.

PubMed

Wiegand, Annette; Attin, Thomas

2007-05-01

Dental erosion is characterized as a disorder with a multifactorial aetiology including environmental acid exposure. The purpose of this article was to summarize and discuss the available information concerning occupational dental erosion. Information from original scientific papers, case reports and reviews with additional case reports listed in PubMed, Medline or EMBASE [search term: (dental OR enamel OR dentin) AND (erosion OR tooth wear) AND (occupational OR worker)] were included in the review. References from the identified publications were manually searched to identify additional relevant articles. The systematic search resulted in 59 papers, of which 42 were suitable for the present review. Seventeen papers demonstrated evidence that battery, galvanizing and associated workers exposed to sulphuric or hydrochloric acid were at higher risk of dental erosion. For other industrial workers, wine tasters and competitive swimmers, only a few clinical studies exist and these do not allow the drawing of definitive conclusions. Occupational acid exposure might increase the risk of dental erosion. Evidence for occupational dental erosion is limited to battery and galvanizing workers, while data for other occupational groups need to be confirmed by further studies.

Risks associated with tendinitis: effects from demographic, socioeconomic, and psychological status among Brazilian workers.

Self-reported tendinitis/tenosynovitis was evaluated by gender, age group, skin color, family income, and educational and psychological status. !The study was carried out in a representative sample of formally contracted Brazilian workers from a household survey. A total of 54,660 participants were included. Occupations were stratified according to estimated prevalences of self-reported injuries. Non-conditional logistic regression was performed, and all variables were analyzed in two occupational groups. The overall prevalence rate of tendinitis/tenosynovitis was 3.1%: 5.5% in high-prevalence occupations (n = 10,726); and 2.5% in low-prevalence occupations (n = 43,934). White female workers between the ages of 45 and 64 years and at a higher socioeconomic level were more likely to report tendinitis/tenosynovitis regardless of their occupational category. An adjusted OR = 3.59 [95% CI: 3.15--4.09] was found between tendinitis/tenosynovitis and psychological status. Among formally contracted Brazilian workers, higher income can imply greater physical and psychological demands that, regardless of occupational stratum, increase the risk of tendinitis/tenosynovitis.

Why change. A look at the current system of disability determination and workers' compensation for occupational lung disease

1982-12-01

Under the current system of disability determination and workers' compensation for occupational lung disease, disabled workers or their survivors can reasonably count on being compensated. However, by rejecting established scientific truth in order to pay workers' compensation in circumstances where disability or death had not been due to occupation, the system has operated unfairly and has undermined public confidence and respect. To gain more scientific integrity and fairness, the system should be changed to provide for adjudication by scientifically informed disability boards. The adversary system sould be retained, however, as needed protection against bias, quackery, and mendacity.

We describe the case of two workers evaluated in our occupational health unit. The first worker was a kitchen aide; the second was a primary care physician. Both had been diagnosed with narcolepsy and had obvious disability.We assessed occupational hazards related to their jobs, analysed their tasks, and performed medical examinations. Afterwards, we offered recommendations to the patients, consisting of avoidance of situations involving a risk of work accidents and improving their sleep habits. Narcolepsy is a rare disorder, but it has important social and occupational consequences. A better understanding of the disease and some work accommodations can help improve the quality of life of affected workers.

Occupational disease and workers' compensation: coverage, costs, and consequences.

PubMed

Leigh, J Paul; Robbins, John A

2004-01-01

Most of the costs of occupational disease are not covered by workers' compensation. First, the authors estimated the deaths and costs for all occupational disease in 1999, using epidemiological studies. Among the greatest contributors were job-related cancer, chronic respiratory disease, and circulatory disease. Second, the authors estimated the number of workers' compensation cases, costs, and deaths for 1999, using data from up to 16 states representing all regions of the country. Unlike the epidemiological studies that emphasized fatal diseases, the workers' compensation estimates emphasized nonfatal diseases and conditions like tendonitis and hernia. Comparisons of the epidemiological and workers' compensation estimates suggest that in 1999, workers' compensation missed roughly 46,000 to 93,000 deaths and 8 billion US dollars to 23 billion US dollars in medical costs. These deaths and costs represented substantial cost shifting from workers' compensation systems to individual workers, their families, private medical insurance, and taxpayers (through Medicare and Medicaid). Designing policies to reduce the cost shifting and its associated inefficiency will be challenging.

Common Mental Disorders among Occupational Groups: Contributions of the Latent Class Model

Martins Carvalho, Fernando; de Araújo, Tânia Maria

2016-01-01

Background. The Self-Reporting Questionnaire (SRQ-20) is widely used for evaluating common mental disorders. However, few studies have evaluated the SRQ-20 measurements performance in occupational groups. This study aimed to describe manifestation patterns of common mental disorders symptoms among workers populations, by using latent class analysis. Methods. Data derived from 9,959 Brazilian workers, obtained from four cross-sectional studies that used similar methodology, among groups of informal workers, teachers, healthcare workers, and urban workers. Common mental disorders were measured by using SRQ-20. Latent class analysis was performed on each database separately. Results. Three classes of symptoms were confirmed in the occupational categories investigated. In all studies, class I met better criteria for suspicion of common mental disorders. Class II discriminated workers with intermediate probability of answers to the items belonging to anxiety, sadness, and energy decrease that configure common mental disorders. Class III was composed of subgroups of workers with low probability to respond positively to questions for screening common mental disorders. Conclusions. Three patterns of symptoms of common mental disorders were identified in the occupational groups investigated, ranging from distinctive features to low probabilities of occurrence. The SRQ-20 measurements showed stability in capturing nonpsychotic symptoms. PMID:27630999

Occupational health and safety among commercial sex workers.

PubMed

Ross, Michael W; Crisp, Beth R; Månsson, Sven-Axel; Hawkes, Sarah

2012-03-01

The concept of occupational health and safety (OHS) for commercial sex workers has rarely been investigated, perhaps because of the often informal nature of the workplace, the associated stigma, and the frequently illegal nature of the activity. We reviewed the literature on health, occupational risks, and safety among commercial sex workers. Cultural and local variations and commonalities were identified. Dimensions of OHS that emerged included legal and policing risks, risks associated with particular business settings such as streets and brothels, violence from clients, mental health risks and protective factors, alcohol and drug use, repetitive strain injuries, sexually transmissible infections, risks associated with particular classes of clients, issues associated with male and transgender commercial sex workers, and issues of risk reduction that in many cases are associated with lack of agency or control, stigma, and legal barriers. We further discuss the impact and potential of OHS interventions for commercial sex workers. The OHS of commercial sex workers covers a range of domains, some potentially modifiable by OHS programs and workplace safety interventions targeted at this population. We argue that commercial sex work should be considered as an occupation overdue for interventions to reduce workplace risks and enhance worker safety.

Noise-induced hearing loss in small-scale metal industry in Nepal.

There has been no previous research to demonstrate the risk of noise-induced hearing loss in industry in Nepal. Limited research on occupational noise-induced hearing loss has been conducted within small-scale industry worldwide, despite it being a substantial and growing cause of deafness in the developing world. The study involved a cross-sectional audiometric assessment, with questionnaire-based examinations of noise and occupational history, and workplace noise level assessment. A total of 115 metal workers and 123 hotel workers (control subjects) were recruited. Noise-induced hearing loss prevalence was 30.4 per cent in metal workers and 4.1 per cent in hotel workers, with a significant odds ratio of 10.3. Except for age and time in occupation, none of the demographic factors were significant in predicting outcomes in regression analyses. When adjusted for this finding, and previous noise-exposed occupations, the odds ratio was 13.8. Workplace noise was significantly different between the groups, ranging from 65.3 to 84.7 dBA in metal worker sites, and from 51.4 to 68.6 dBA in the control sites. Metal workers appear to have a greater risk of noise-induced hearing loss than controls. Additional research on occupational noise-induced hearing loss in Nepal and small-scale industry globally is needed.

Medical monitoring of asbestos-exposed workers: experience from Poland

Abstract In Poland, the use of asbestos was banned in 1997 and asbestos plants have been closed since then. Despite their closure, cases of asbestos-related occupational diseases among former asbestos workers are still being recorded in the Central Register of Occupational Diseases. Between 2001 and 2014, there were 2726 asbestos-related illnesses, classified and reported as diseases associated with occupational exposure to asbestos. In 2000, Poland introduced a programme called Amiantus, targeted at former asbestos-processing plant workers. The programme provided periodic medical examinations to workers and free access to medications for treatment of asbestos-related illnesses. Introduction of the programme provided additional data to generate a reliable estimation of the number of asbestos-related occupational diseases, including cancer. The average latency period for asbestosis, lung cancer and mesothelioma is about 40 years so there may still be some health impact to former workers necessitating follow-up. We present the Polish experience of implementing a medical examination programme for asbestos-exposed workers and provide a list of activities to consider when planning for such a programme.

Rates of occupational injury among immigrant workers are widely believed to be underestimated. The goal of this study was to enhance understanding of the burden of occupational injury and the work organization factors underlying injury among immigrant Latino residential construction workers. Prospective data were obtained from a community-based sample of Latino residential construction workers (N = 107) over a 3-month period. Twenty-eight participants were injured, resulting in an injury incidence rate of 55.0/100 FTE (95% CI = 41.4-71.6) during the 3-month observation period. The injury rate involving days away from work during the observation period was 3.9/100 FTE (CI = 0.2-7.2). Injuries were elevated among roofers relative to framers and general construction workers. Roofers had elevated exposure to a variety of deleterious work organization factors. Although imprecise given the small sample, our results suggest a threefold to fourfold underestimate of the injury burden to immigrant Latino construction workers. Work organization may contribute to elevated rates of non-fatal occupational injury, particularly among roofers. Copyright © 2012 Wiley Periodicals, Inc.

Using data from the National Health and Nutrition Examination Survey (2001-2004), multiple logistic regression was used to investigate associations between industry and occupation and current asthma as defined by positive responses to "Has a doctor or other health professional ever told you that you have asthma?" and "Do you still have asthma?" Workers in mining (17.0%), health-related industries (12.5%), teaching (13.1%), or in health-related occupations (12.6%) had the highest prevalence of asthma. As compared to construction industry workers, workers in mining (aOR = 5.2, 95% CI: 1.1-24.2) or health-related (aOR = 2.3, 95% CI: 1.1-4.8) industries had significantly higher odds of asthma. Our study adds to the increasing evidence that miners, healthcare workers and teachers remain high-risk working populations and appropriate evaluation and control measures are needed to protect these workers. 2010 Wiley-Liss, Inc.

The objective of this paper is to review the available workers compensation and occupational health and safety data and the legal framework in relation to the agricultural industry to explore whether any factors highlight the need to pay special attention to the particular circumstances of those engaged in the industry. This paper explores some of the special features of the agricultural industry, looking first at agricultural worker fatalities and injuries as a matter of ongoing concern for all participants in this industry, government, as well as occupational health and workers compensation authorities. The paper analyses how occupational health and workers compensation laws may have special application to this industry. Finally, the paper considers some workers compensation provisions that have particular application to the agricultural industry. Our survey of the available data and literature leads to the conclusion that the dangerous nature of agricultural work and the special legal and economic framework in which that work is undertaken identify the agricultural industry as presenting Australian Governments and specialist authorities with particular challenges in relation to improving workplace safety and reducing workplace injury.

The aim of this manuscript is to provide an environmental assessment of the creation and use of waste foundry sand (WFS) via an LCA in a foundry for grey cast iron. A life cycle impact assessment was carried out using SimaPro 8. This environmental analysis assessed the impact of creating waste foundry sand (WFS) in a foundry, Hronec (Slovakia, Central Europe). According to BREF, this foundry is classified as an iron foundry with a production capacity greater than 20 t/day with processes typical for grey cast iron foundries. Molten metal is poured into single-use sand moulds. We identified those factors influencing the creation and use of WFS which significantly affect the quality of the environment. The use of WFS from the production of cores in regenerated moulding mixtures with installed circuits brings marked minimisation of material and energy inputs in the processes of creating WFS and it positively influences the consumption of resources and the quality of the ecosystem. Space for lessening the impact of WFS processes upon the consumption of resources and ecosystem quality is mainly found in recycling WFS in the building sector. In the next step, it is necessary to thoroughly verify the eco-toxicological properties of not only the created WFS and other foundry waste, but mainly the building products for which this waste is used. In terms of transportation, it is important that waste is recycled at local level. The processes of creating WFS have a marked influence upon all the selected waste categories (consumption of resources, ecosystem quality, human health). By minimising material inputs into processes and the effective adjustment of production technology, a foundry can significantly lessen the impacts of processes for creating WFS upon the environment.

Fitness for work in health care workers from the prospective of ethics, science and good practices.

PubMed

2012-01-01

Fitness for work (FFW) is the final task of both risk assessment and health surveillance, aimed at protecting workers' health and working capacity. There are numerous specific concerns regarding health care workers. In particular: i) the frequent difficulty in determining at pre-employment/pre-placement examinations the specific task that the individual worker will perform; ii) the prevalence of female workers and the contemporary presence of numerous occupational risk factors that are a potential cause of harmful effects on women's reproductive health; iii) the progressive aging of the staff especially nurses; iv) the risk to third parties, with particular reference to the issues of biological risk and substance abuse, also in relation to shift work, fatigue and occupational stress; v) the increasing number of immigrant workers among support staff In such cases the occupational physician, respecting both ethical principles and regulations and with an appropriate balance between scientific evidence and the precautionary principle, should express a FFW judgment that allows both the adaptation of work to the worker and vice versa, as recommended by the World Health Organization (WHO) and the International Commission on Occupational Health (ICOH). Proper FFW judgment also permits the expected benefits to be achieved, not only for the workers but also for employers, companies and society.

Prevalence patterns of dermatitis among workers offer clues about risk factors and targets for prevention, but population-based estimates of the burden of dermatitis among US workers are lacking. Data from an occupational health supplement to the 2010 National Health Interview Survey (NHIS-OHS) were used to estimate the prevalence of dermatitis overall and by demographic characteristics and industry and occupation (I&O) of current/recent employment. Data were available for 27,157 adults, including 17,524 current/recent workers. The overall prevalence rate of dermatitis among current/recent workers was 9.8% (range among I&O groups: 5.5-15.4%), representing approximately 15.2 million workers with dermatitis. The highest prevalence rates were among I&O groups related to health care. Overall, 5.6% of dermatitis cases among workers (9.2% among healthcare workers) were attributed to work by health professionals. Dermatitis affected over 15 million US workers in 2010, and its prevalence varied by demographic characteristics and industry and occupation of employment. The prevalence rate of work-related dermatitis based on the NHIS-OHS was approximately 100-fold higher than incidence rates based on the Bureau of Labor Statistics' Survey of Occupational Illness and Injury. Published 2012. This article is a U.S. Government work and is in the public domain in the USA.

In China, there have been an increasing number of migrant workers from rural to urban areas, and migrant workers have the highest incidence of occupational diseases. However, few studies have examined the impact of occupational stress on job burnout in these migrant workers. This study aimed to investigate the relationship between occupational stress and job burnout among migrant workers. This study used a cross-sectional survey. This investigation was conducted in Dongguan city, Guangdong Province, China. 3806 migrant workers, aged 18-60 years, were randomly selected using multistage sampling procedures. Multistage sampling procedures were used to examine demographic characteristics, behaviour customs and job-related data. Hierarchical linear regression and logistic regression models were constructed to explore the relationship between occupational stress and burnout. Demographics, behaviour customs and job-related characteristics significantly affected on burnout. After adjusting for the control variable, a high level of emotional exhaustion was associated with high role overload, high role insufficiency, high role boundary, high physical environment, high psychological strain, high physical strain, low role ambiguity, low responsibility and low vocational strain. A high level of depersonalisation was associated with high role overload, high role ambiguity, high role boundary, high interpersonal strain, high recreation, low physical environment and low social support. A low level of personal accomplishment was associated with high role boundary, high role insufficiency, low responsibility, low social support, low physical environment, low self-care and low interpersonal strain. Compared to the personal resources, the job strain and personal strain were more likely to explain the burnout of rural-to-urban migrant workers in our study. The migrant workers have increased job burnouts in relation to occupational stress. Relieving occupational stress and maintaining an appropriate quantity and quality of work could be important measures for preventing job burnout among these workers.

Objective: To investigate the mental health status of railway female workers and related influencing factors, and to provide a scientific strategy for labor protection regulations in railway female workers. Methods: Cluster sampling was used to select 5033 female workers from Jinan, Nanning, Qinghai-Tibet, and Wuhan railway systems in China from January to August, 2016. A uniform reproductive health questionnaire, as well as the Symptom Checklist-90 (SCL-90) , was used to investigate their general information (age, marital status, education level, and family income) , work type (day shift, night shift, or work on shift) , work position, and the presence or absence of exposure to occupational hazardous factors. The score on each factor of SCL-90 and the positive rate of mental health status were calculated. Results: The positive rate of mental health status was 10.6% in railway female workers. The workers exposed to occupational hazardous factors had a significantly higher positive rate of mental health status than those not exposed to occupational hazardous factors (14.20% vs 8.02%, P <0.01) . There were significant differences in the positive rate of mental health status between workers with different ages, marital status, education levels, histories of abortion, or annual family income levels ( P <0.01) . The scores of somatization (1.54±0.62) and horror (1.28±0.47) in SCL-90 were significantly higher than the Chinese adult norm ( P <0.01) . The multivariate logistic regression analysis showed that exposure to occupational hazardous factors, night shift, overwork, and carrying heavy objects were associated with mental health problems ( OR =1.797, 95% CI : 1.393-2.318; OR =0.641, 95% CI : 0.498-0.827; OR =0.586, 95% CI : 0.439-0.783; OR =0.580, 95% CI : 0.378-0.890) . Conclusion: Railway female workers have lower levels of mental health than the general population and are under significant occupational stress. Exposure to occupational hazardous factors, night shift, overwork, and carrying heavy objects are associated with the development of mental health problems in railway female workers.

Bronchial asthma and COPD due to irritants in the workplace - an evidence-based approach

PubMed Central

2012-01-01

Background Respiratory irritants represent a major cause of occupational obstructive airway diseases. We provide an overview of the evidence related to irritative agents causing occupational asthma or occupational COPD. Methods We searched MEDLINE via PubMed. Reference lists of relevant reviews were also screened. The SIGN grading system was used to rate the quality of each study. The modified RCGP three-star system was used to grade the body of evidence for each irritant agent regarding its causative role in either occupational asthma or occupational COPD. Results A total of 474 relevant papers were identified, covering 188 individual agents, professions or work-sites. The focus of most of the studies and the predominant diagnosis was occupational asthma, whereas occupational COPD arose only incidentally. The highest level assigned using the SIGN grading was 2+ (well-conducted systematic review, cohort or case–control study with a low risk of confounding or bias). According to the modified RCGP three-star grading, the strongest evidence of association with an individual agent, profession or work-site (“**”) was found for 17 agents or work-sites, including benzene-1,2,4-tricarboxylicacid-1,2-anhydride, chlorine, platinum salt, isocyanates, cement dust, grain dust, animal farming, environmental tobacco smoke, welding fumes or construction work. Phthalic anhydride, glutaraldehyde, sulphur dioxide, cotton dust, cleaning agents, potrooms, farming (various), foundries were found to be moderately associated with occupational asthma or occupational COPD (“*[+]”). Conclusion This study let us assume that irritant-induced occupational asthma and especially occupational COPD are considerably underreported. Defining the evidence of the many additional occupational irritants for causing airway disorders will be the subject of continued studies with implications for diagnostics and preventive measures.

Objective To compare occupational psychosocial hazards in green collar versus non-green collar workers. Methods Standard Occupational Classification codes were used to link the 2010 National Health Interview Survey to the 2010 Occupational Information Network Database. Multivariable logistic regressions were used to predict job insecurity, work-life imbalance, and workplace harassment in green versus non-green collar workers. Results Most participants were white, non-Hispanic, 25–64 years of age, and obtained greater than a high school education. The majority reported not being harassed at work, no work-life imbalance, and no job insecurity. Relative to non-green collar workers (n=12,217), green collar workers (n=2,588) were more likely to report job insecurity (OR=1.13; 95% CI=1.02–1.26) and work-life imbalance (1.19; 1.05–1.35), but less likely to experience workplace harassment (0.77; 0.62–0.95). Conclusions Continuous surveillance of occupational psychosocial hazards is recommended in this rapidly emerging workforce. PMID:28045790

The purpose of this study was to assess the major risk factors for hypertension in oil workers, and investigate the effect of occupational stress on the incidence of hypertension after controlling for other risk factors. A prospective cohort approach was used following enrollment of 1354 oil workers. The occupational stress experienced by oil workers was higher than for the general population in China. By the end of the cohort study, 231 new cases of hypertension among the oil workers had been diagnosed. The cumulative incidence of hypertension was 17.06%. There were 44, 112, and 75 workers who developed hypertension in the low, intermediate, and high occupational stress groups, which represented a 12.0%, 15.6%, and 20.3% cumulative incidence, respectively (chi-square value = 9.812, p < 0.01). Multivariate Cox proportional hazard model analysis showed that type of work, cigarette smoking, excess body weight, and obesity were risk factors for hypertension ( p < 0.05). After risk factors such as type of work, cigarette smoking, alcohol consumption, and body mass index (BMI) were controlled, the hypertension risk (hazard ratio, HR) in the high occupational stress group was 1.549 (1.072-2.236) compared to the low exposure group, and 2.337 (1.191-4.585) in female subjects. Our study indicated that an increase in occupational stress was associated with an increased risk of hypertension after other factors were adjusted.

To provide evidence for the prevention and treatment of occupational diseases by the analysis of existing major occupational hazards and health conditions of workers in a large shipbuilding factory. Field investigation of occupational conditions was conducted to examine the existence of occupational hazards from 2009 to 2012 in a large shipbuilding factory, and then the results of physical examination among its workers were analyzed. Other than the metal dust (total dust), the levels of other dusts and manganese dioxide were beyond the national standard to various degrees, and through a sampling point detection, it was found that the levels of manganese dioxide exceeded the standard by 42.8%. The maximum time-weighted average concentration in individuals was 27.927 mg/m(3), much higher than the national standard limit. For harmful gas detection in individuals, xylene was 38.4%above the standard level (the highest concentration reached 1447.7 mg/m(3)); moreover, both toluene and ethylbenzene exceeded the national standard at different levels. Among the noise-exposed workers, 71%worked in the environment where the daily noise was above the limit of the national standard (85 dB). Physical examinations in 2010 and 2012 showed that the abnormal rate of audiometry in workers was higher than 15%. Dust (total dust), manganese dioxide, benzene, and noise are the main occupational hazards among the workers in the large shipbuilding factory, and strict protection and control for these hazards should be implemented for the workers in the factory.

Background: Asbestos-related diseases (ARD) are occupational hazards with high mortality rates. To identify asbestos exposure by previous occupation is the main issue for ARD compensation for workers. This study aimed to identify risk groups by applying standard classifications of industries and occupations to a national database of compensated ARD victims in Japan. Methods: We identified occupations that carry a risk of asbestos exposure according to the International Standard Industrial Classification of All Economic Activities (ISIC). ARD compensation data from Japan between 2006 and 2013 were retrieved. Each compensated worker was classified by job section and group according to the ISIC code. Risk ratios for compensation were calculated according to the percentage of workers compensated because of ARD in each ISIC category. Results: In total, there were 6,916 workers with ARD who received compensation in Japan between 2008 and 2013. ISIC classification section F (construction) had the highest compensated risk ratio of 6.3. Section C (manufacturing) and section F (construction) had the largest number of compensated workers (2,868 and 3,463, respectively). In the manufacturing section C, 9 out of 13 divisions had a risk ratio of more than 1. For ISIC divisions in the construction section, construction of buildings (division 41) had the highest number of workers registering claims (2,504). Conclusion: ISIC classification of occupations that are at risk of developing ARD can be used to identify the actual risk of workers’ compensation at the national level.

Lloyd Davies, T. A., Doig, A. T., Fox, A. J., and Greenberg, M. (1973).British Journal of Industrial Medicine,30, 227-231. A radiographic survey of monumental masonry workers in Aberdeen. A survey of radiographic appearances of the lungs of monumental masonry workers in Aberdeen was carried out to determine the present prevalence of abnormalities and to serve as a standard for future comparisons in view of changes in methods of working. No major change could be detected in the status of these granite workers in Aberdeen over the past 20 years but the different methods of survey used by Mair in 1951 and by the present study did not allow of strict comparison. Chest radiographs were reported on by three readers independently using the National Coal Board elaboration of the ILO classification and a score was given to each film using Oldham's method. Multiple regression analysis showed that ϰ-ray changes were related to years in granite but progression was slow in comparison with foundry workers. The prevalence of radiographic appearances of category 1 or greater was 3·0% overall and 4·6% for workers in dusty jobs. Evidence of pneumoconiosis was not observed in workers exposed for less than 20 years. With the environmental control attained the threshold limit values for respirable dust were not often much exceeded. PMID:4353240

The metal leaching characteristics and volatile organic compounds (VOCs) of five different types of waste foundry sands were analyzed with the toxicity characteristic leaching procedure (TCLP) and head space-gas chromatography (HS-GC). Microtox and soil dehydrogenase activity (DHA) tests were then used to evaluate the bio-effects of these waste sands. The results showed that due to the different metals poured and casting materials used to make the sand molds, there was significant difference among the five waste foundry sands in the compositions and concentrations of metal and organic pollutants. The concentrations of Fe in the leachates of iron and steel casting waste foundry sand exceeded the maximal allowable concentrations specified in the National Standard of Drinking Water Quality, whereas the As concentration in the leachate of aluminum casting waste foundry sand exceeded the standard. The five waste foundry sands had quite different compositions and levels of VOCs, which resulted in different levels of inhibition effects on the luminescent bacteria (30% and 95%). Additionally, the soil DHA tests suggested that metal pollutants in waste foundry sands may inhibit the soil microbial activity, whereas organics in the sands may slightly promote the microbial activity. The results of this study indicated that the waste foundry sands may pose considerable threat to the environment when improperly disposed.

National nanotechnology partnership to protect workers

Howard, John; Murashov, Vladimir

Nanotechnology is predicted to improve many aspects of human life. By 2015, it is estimated to represent 3.1 trillion in manufactured goods. Data is emerging that exposure to nanomaterials may pose a health risk to workers. If the economic promise of nanotechnology is to be achieved, ways need to be found to protect nanotechnology workers now. The Occupational Safety and Health Act of 1970 (OSHAct) gave the responsibility to protect workers to the Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health (NIOSH) through research, standards adoption, and standards enforcement. Since 1980, adopting new occupational health standards has grown more complex. The increased complexity has greatly slowed efforts to adopt protective standards for toxic agents that are well-known to pose significant risks. The likelihood of rapidly adopting standards to protect workers from nanomaterials, whose risks are just emerging, seems even more unlikely. Use of the OSHAct's general duty clause to protect workers also seems uncertain at this time. In the interim, a national partnership led by NIOSH involving nanotech manufacturers and downstream users, workers, academic researchers, safety, and health practitioners is proposed. A National Nanotechnology Partnership would generate knowledge about the nature and the extent of worker risk, utilize that knowledge to develop risk control strategies to protect nanotechnology workers now, and provide an evidence base for NIOSH recommendations to OSHA for a nanotechnology program standard at a future date.

The association between occupational exposure and stomach cancer was investigated in a multicenter case-referent study conducted in Spain on 354 histologically confirmed cases and 354 hospital referents, matched by age, gender, and residence. An increased risk of gastric cancer was found for coal mining workers [odds ratio (OR) 11.8], but the number of workers was small, and therefore the 95% confidence interval (95% CI) was wide (95% CI 1.36-103). An increased risk was observed for wood and furniture workers (OR 1.76), construction workers (OR 1.68), and glass and ceramic workers (OR 2.18), but none of these risks were statistically significant. According to an occupation-exposure linkage system an increased risk was found for occupations associated with exposure to silica and mineral dust (OR 1.80, 95% CI 0.90-3.59). All of the OR estimates were adjusted for the confounding factors socioprofessional status and dietary habits. The possibility of a causal association between stomach cancer and coal and mineral dust is supported by the results.

Objective Physical inactivity has been hypothesized as an underlying factor for the association between shift work and adverse health outcomes. We compared leisure-time and occupational physical activity and sedentary behavior between day, night, and non-night shift workers. Methods We identified 612 day workers, 139 night shift workers and 61 non-night shift workers aged 18-65 years (54% men) in two Danish studies: the New method for Objective Measurements of physical Activity in Daily living (NOMAD) and the Danish Physical ACTivity cohort with Objective measurements (DPhacto) between 2011-2013. Sedentary behavior, light, and moderate-to-vigorous physical activity were measured using an accelerometer. Physical activity was expressed as percentage of leisure and work time spent in each activity. Linear regression analyses were used to test differences in physical activity and sedentary behavior between day, night, and non-night shift workers. Results No differences in leisure-time sedentary behavior and physical activity were observed between day and shift workers (P>0.05). Non-night shift workers spent 7.2% [95% confidence interval (95% CI) 2.3-12.1) more time in occupational sedentary behavior than day workers and 5.9% (95% CI -10.1- -1.7) and 1.9% (95% CI -3.7- -0.2) less time in occupational light and moderate-to-vigorous physical activity, respectively. Compared to day workers, night shift workers spent 4.3% (95% CI 2.4-6.1) more time at work in uninterrupted sedentary periods of ≥30 minutes. Conclusions Shift workers had similar leisure-time physical activity patterns as day workers, but were more sedentary at work. Future research should elucidate whether occupational physical inactivity and sedentary behavior contributes to shift work-related adverse health effects.

The identification of industry, occupation, and associated injury costs for worker falls in Kentucky have not been fully examined. The purpose of this study was to determine the associations between industry and occupation and 1) hospitalization length of stay; 2) hospitalization charges; and 3) workers' claims costs in workers suffering falls, using linked inpatient hospitalization discharge and workers' claims data sets. Hospitalization cases were selected with ICD-9-CM external cause of injury codes for falls and payer code of workers' claims for years 2000-2004. Selection criteria for workers'claims cases were International Association of Industrial Accident Boards and Commissions Electronic Data Interchange Nature (IAIABCEDIN) injuries coded as falls and/or slips. Common data variables between the two data sets such as date of birth, gender, date of injury, and hospital admission date were used to perform probabilistic data linkage using LinkSolv software. Statistical analysis was performed with non-parametric tests. Construction falls were the most prevalent for male workers and incurred the highest hospitalization and workers' compensation costs, whereas most female worker falls occurred in the services industry. The largest percentage of male worker falls was from one level to another, while the largest percentage of females experienced a fall, slip, or trip (not otherwise classified). When male construction worker falls were further analyzed, laborers and helpers had longer hospital stays as well as higher total charges when the worker fell from one level to another. Data linkage of hospitalization and workers' claims falls data provides additional information on industry, occupation, and costs that are not available when examining either data set alone.

Health-care workers are at risk of exposure to occupational infections with subsequent risk of contracting diseases, disability, and even death. A systematic collection of occupational disease data is useful for monitoring current trends in work situations and disease exposures; however, these data are usually limited due to under-reporting. The objective of this study was to review literature related to knowledge, risk perceptions, and practices regarding occupational exposures to infectious diseases in Malaysian health-care settings, in particular regarding blood-borne infections, universal precautions, use of personal protective equipment, and clinical waste management. The data are useful for determining improvements in knowledge and risk perceptions among health-care workers with developments of health policies and essential interventions for prevention and control of occupational diseases.

The occupational stress is associated with dissatisfaction, excessive demand at work and personal factors. Those factors can reduce work performance and can predispose workers to various diseases. Workers' health may be protected if there is encouragement to face challenges, which may lessen the impact on psychological and somatic stress and thus have greater personal and professional satisfaction. The aim of this study was to evaluate the association between occupational stress and work engagement. Participated in this study 457 male and female workers of a metallurgical industry. Subjects answered personal data, and the Job Stress Scale and Utrecht Work Engagement Scale were applied. Results showed an association between occupational stress and work engagement (P=0,001). The way the individual deals with his frustrations, or rather the work engagement, is associated with the occupational stress.

Examine uses of US workers' compensation (WC) data for occupational safety and health purposes. This article is a summary of the proceedings from an invitational workshop held in September 2009 to discuss the use of WC data for occupational safety and health prevention purposes. Workers' compensation data systems, although limited in many ways, contain information such as medical treatments, their costs and outcomes, and disability causes that are unavailable from national occupational surveillance sources. Despite their limitations, WC records are collected in a manner consistent with many occupational health and safety surveillance needs. Reports are available on the use of WC data for surveillance and research purposes such as estimating the frequency, magnitude, severity, and cost of compensated injuries. Inconsistencies in WC data can limit generalization of research results.

Although routine workers' health examinations are extensively performed worldwide with important resource allocation, few studies have analyzed their quality. The objective of this study has been to analyze the medical practice of workers' health examinations in Catalonia (Spain) in terms of its occupational preventive aim. A cross-sectional study was carried out by means of an online survey addressed to occupational physicians who were members of the Catalan Society of Safety and Occupational Medicine. The questionnaire included factual questions on how they performed health examinations in their usual practice. The bivariate analysis of the answers was performed by type of occupational health service (external/internal). The response rate was 57.9% (N = 168), representing 40.3% of the reference population. A high percentage of occupational physicians had important limitations in their current medical practice, including availability of clinical and exposure information, job-specificity of tests, and early detection and appropriate management of suspected occupational diseases. The situation in external occupational health services - that covered the great majority of Catalan employees - was worse remarkably in regard to knowledge of occupational and nonoccupational sickness absence data, participation in the investigation of occupational injuries and diseases, and accessibility for workers to the occupational health service. This study raises serious concerns about the occupational preventive usefulness of these health examinations, and subsequently about our health surveillance system, based primarily on them. Professionals alongside health and safety institutions and stakeholders should promote the rationalization of this system, following the technical criteria of need, relevance, scientific validity and effectiveness, whilst ensuring that its ultimate goal of improving the health and safety of workers in relation to work is fulfilled. Other countries with similar surveillance systems might be encouraged by our results to assess how their practices fit the intended purpose. Int J Occup Med Environ Health 2017;30(6):823-848.

Because of the increasing number of older workers, it is important to develop models of work-related constructs for this population. The present article developed a model surrounding occupational self-efficacy, testing its relation to other factors (e.g., intrinsic job motivation), predictors (e.g., self-perceptions of aging), and outcomes (e.g., job satisfaction). Employed adults of ages 50 and older (n= 313) were recruited via organizations and social media sites. Study participants (M= 59.7, SD= 6.1, range = 50–78) volunteered to fill out an Internet survey. Occupational self-efficacy predicted job satisfaction, and intrinsic job motivation fully mediated this relationship. More negative self-perceptions of aging predicted poorer occupational self-efficacy. Occupational self-efficacy also predicted life satisfaction. Expected retirement age and job performance were unrelated to occupational self-efficacy. These findings may inform workplace interventions that seek to maintain or increase older worker job and life satisfaction. PMID:26394821

Background This article introduces some key labor, economic, and social policies that historically and currently impact occupational health disparities in the United States. Methods We conducted a broad review of the peer-reviewed and gray literature on the effects of social, economic, and labor policies on occupational health disparities. Results Many populations such as tipped workers, public employees, immigrant workers, and misclassified workers are not protected by current laws and policies, including worker’s compensation or Occupational Safety and Health Administration enforcement of standards. Local and state initiatives, such as living wage laws and community benefit agreements, as well as multiagency law enforcement contribute to reducing occupational health disparities. Conclusions There is a need to build coalitions and collaborations to command the resources necessary to identify, and then reduce and eliminate occupational disparities by establishing healthy, safe, and just work for all.

To examine the health-related quality of life among workers in 22 standard occupation groups using data from the 2013-2014 US Behavioral Risk Factor Surveillance System. We examined the health-related quality of life measures of self-rated health, frequent physical distress, frequent mental distress, frequent activity limitation, and frequent overall unhealthy days by occupation group for 155 839 currently employed adults among 17 states. We performed multiple logistic regression analyses that accounted for the Behavioral Risk Factor Surveillance System's complex survey design to obtain prevalence estimates adjusted for potential confounders. Among all occupation groups, the arts, design, entertainment, sports, and media occupation group reported the highest adjusted prevalence of frequent physical distress, frequent mental distress, frequent activity limitation, and frequent overall unhealthy days. The personal care and service occupation group had the highest adjusted prevalence for fair or poor self-rated health. Workers' jobs affect their health-related quality of life.

Petrochemical industries are known as sources of many toxic chemicals. Safety and health risks of the petrochemical workers employed at Map Ta Phut Industrial Estate, located in Rayong, Thailand, are potentially high. The research materials consisted of documents emanating from statutory reports on safety in working with toxic chemicals and the results of interviews by questionnaire among 457 petrochemical workers regarding occupational health and safety issues. Most of workers who were working with toxic chemicals had knowledge and awareness of health risks and chemical hazards at work. We found that safe behavior at work through read the safety information among operational workers less than non-operational workers around 10%. Most of workers had perceived occupational health and safety management in their companies. Some companies revealed that they had not been performing biological monitoring of blood or urine for their health examination reports and that workplace exposure monitoring had not correlated well with health examination of workers. Our study suggested that occupational health and safety for petrochemical industries requires standards and guidelines for workers' health surveillance aimed at protection of workers.

The consequences of sleep deprivation and sleepiness have been noted as the most important health problem in our modern society among shift workers. The objective of this study was to investigate the prevalence of sleep disorders and their possible effects on work performance in two groups of Iranian shift workers and nonshift workers. This study was designed as a cross-sectional study. The data were collected by PSQI, Berlin questionnaire, Epworth Sleepiness Scale, Insomnia Severity Index, and RLS Questionnaire. Occupational impact of different sleep disorders was detected by Occupational Impact of Sleep Disorder questionnaire. These questionnaires were filled in by 210 shift workers and 204 nonshift workers. There was no significant difference in the age, BMI, marital status, and years of employment in the two groups. Shift workers scored significantly higher in the OISD. The prevalence of insomnia, poor sleep quality, and daytime sleepiness was significantly higher in shift workers. Correlations between OISD scores and insomnia, sleep quality, and daytime sleepiness were significant. We concluded that sleep disorders should receive more attention as a robust indicator of work limitation. PMID:24977041

Occupational population-based epidemiological data relating to occupational contact allergies in the Chinese clothing industry are limited. To investigate the prevalence of occupational allergic contact dermatitis (OACD) and to identify the causative allergens among clothing employees in China, a cross-sectional study was conducted in 529 clothing employees at 12 clothing factories in Beijing. All employees were subjected to an interview using self-administered questionnaire and skin examination, and those who were diagnosed with occupational contact dermatitis (OCD) were patch tested. In the present survey, we found that the overall 1-year prevalence of OACD among the clothing employees was 8.5%. The 1-year prevalence of OACD among workers (10.8%) was significantly higher than that among managers (3.2%). The lesions were primarily on the hands and wrists in workers, but the face and neck in managers. The major allergens were nickel sulfate and cobalt dichloride in workers and colophony and p -tert-butylphenol formaldehyde resin in managers. In conclusion, workers are at a higher risk of OACD compared with managers in the Chinese clothing industry. In addition to hand dermatitis in workers, airborne contact dermatitis on the face and neck should be also addressed in managers.

2013-01-01

Background Crystalline silica and asbestos are common minerals that occur throughout South Africa, exposure to either causes respiratory disease. Most studies on silicosis in South Africa have been cross-sectional and long-term trends have not been reported. Although much research has been conducted on the health effects of silica dust and asbestos fibre in the gold-mining and asbestos-mining sectors, little is known about their health effects in other mining sectors. Objective The aims of this thesis were to describe silicosis trends in gold miners over three decades, and to explore the potential for diamond mine workers to develop asbestos-related diseases and platinum mine workers to develop silicosis. Methods Mine workers for the three sub-studies were identified from a mine worker autopsy database at the National Institute for Occupational Health. Results From 1975 to 2007, the proportions of white and black gold mine workers with silicosis increased from 18 to 22% and from 3 to 32% respectively. Cases of diamond and platinum mine workers with asbestos-related diseases and silicosis, respectively, were also identified. Conclusion The trends in silicosis in gold miners at autopsy clearly demonstrate the failure of the gold mines to adequately control dust and prevent occupational respiratory disease. The two case series of diamond and platinum mine workers contribute to the evidence for the risk of asbestos-related diseases in diamond mine workers and silicosis in platinum mine workers, respectively. The absence of reliable environmental dust measurements and incomplete work history records impedes occupational health research in South Africa because it is difficult to identify and/or validate sources of dust exposure that may be associated with occupational respiratory disease.

Occupational Health Management in the Lead Industry: The Korean Experience

PubMed Central

2011-01-01

In 1967, the problem of occupational lead exposure came to public attention in Korea. Since then, regular progress has been made in lowering workplace lead exposures, instituting new workplace controls, and implementing health examinations of exposed workers. Past serious lead poisoning episodes made it possible to introduce biological monitoring programs on a voluntary basis in high-lead-exposure facilities in Korea. Industry-specific occupational health services for lead workers in Korea during the last 22 years can be categorized into three phases. During the first phase (1988-1993), efforts were directed at increasing awareness among workers about the hazards of lead exposure, biological monitoring of blood zinc protoporphyrin began, and a respiratory protection program was introduced. During the second phase (1994-1997), a computerized health management system for lead workers was developed, blood-lead measurement was added to biologic monitoring, and engineering controls were introduced in the workplace to lower air-lead levels to comply with air-lead regulations. Finally, during the third phase (1998-present), a new biomarker, bone-lead measurement by X-ray fluorescence, was introduced. Bone-lead measurement proved to be useful for assessing body burden and to demonstrate past lead exposure in retired workers. Occupational health service practice for lead workers, including the industry-specific group occupational health system, has brought considerable success in the prevention of lead poisoning and in reducing the lead burden in Korean lead workers during the last several decades. The successful achievement of prevention of lead poisoning in Korea was a result of the combined efforts of lead workers, employers, relevant government agencies, and academic institutes.

Work disability prevention in rural healthcare workers.

Approximately 20% of healthcare workers in high-income countries such as Australia, Canada and the USA work in rural areas. Healthcare workers are known to be vulnerable to occupational injury and poor work disability outcomes; given their rural-urban distribution, it is possible to compare work disability prevention in rural and urban areas. However, little attention has been paid to work disability prevention issues specific to rural workers, including rural healthcare workers. A comprehensive review of the literature was conducted to identify rural-urban differences in work disability outcomes (defined as the incidence of occupational injury and the duration of associated work absence), as well as risk factors for poor work disability outcomes in rural healthcare workers. The databases MEDLINE, CINAHL, and EMBASE were searched, as were relevant research centers and government agencies, to identify all quantitative and qualitative English-language studies published between 1 January 2000 and 6 October 2009 that discussed occupational injury, work absence duration, work disability management, or risk factors for poor work disability outcomes, for rural workers specifically, or in comparison with urban workers. To ensure inclusion of studies of healthcare workers as a distinct group among other sector-specific groups, a broad search for literature related to all industrial sectors was conducted. Of 860 references identified, 5 discussed work disability outcomes and 25 discussed known risk factors. Known risk factors were defined as factors firmly established to be associated with poor work disability outcomes in the general worker population based on systematic reviews, well-established conceptual models of work disability prevention, and public health literature. Although somewhat conflicting, the evidence suggests that rural healthcare workers experience higher rates of occupational injury compared with urban healthcare workers, within occupational categories. Rural workers also appear to be more vulnerable to prolonged work absence although the data are limited. No studies directly compared risk factors for work disability prevention outcomes between rural and urban healthcare workers. However, potential risk factors were identified at the level of the environment, worker, job, organization, worker compensation system and healthcare access. Important methodological limitations were noted, including unclear definitions of rurality, inadequate methods of urban-rural comparisons such as comparing samples from different countries, and a paucity of studies applying longitudinal or multivariate designs. There is a notable lack of evidence about work disability prevention issues for healthcare workers in rural areas. Available evidence supports the hypothesis that rural healthcare workers are vulnerable to occupational injury, and suggests they are vulnerable to prolonged work absence. They may be particularly vulnerable to poor work disability prevention outcomes due to complex patient needs in the context of risk factors such as heavy workloads, long hours, heavy on-call demands, high stress levels, limited support and workplace violence. Additional vulnerability may occur because their work conditions are managed in distant urban administrative centers, and due to barriers in their own healthcare access. Although rural healthcare workers seem generally at greater risk of injury, one study suggests that urban emergency medical service workers experience a high vulnerability to injury that may outweigh the effects of rurality. Additional research is needed to document rural-urban disparities in work disability outcomes and to identify associated sources and risk factors. Other issues to address are access to and quality of healthcare for rural healthcare workers, streamlining the compensation system, the unique needs of Aboriginal healthcare workers, and the management of prolonged work absence. Finally, occupational injury and work absence duration programs should be tailored to meet the needs of rural workers.

A large and growing population of elderly Koreans with chronic conditions necessitates an increase in long-term care. This study is aimed at investigating the effects of occupational stress, work-centrality, self-efficacy, and job satisfaction on intent to leave among long-term care workers in Korea. We tested the hypothesized structural equation model predicting the intention to quit among long-term care workers in Korea. Survey data were collected from 532 long-term care workers in Seoul, Korea. Results showed that occupational stress was positively associated with intention to leave the job. The study also identified several possible mediators (self-efficacy, work-centrality, job satisfaction) in the relationship between stress and intent to quit. Evidence-based stress management interventions are suggested to help the workers better cope with stressors. Mentoring programs should also be considered for new workers.

Understanding worker health and safety in the rapidly growing legal U.S. cannabis industry is important. Although little published research exists, workers may be exposed to biological, chemical, and physical hazards. This study investigated the Colorado cannabis industry workforce and both physical and psychosocial hazards to worker health and safety. Two hundred and fourteen Colorado cannabis workers completed an online survey after in-person and online recruitment. Participants answered questions about their occupation, job tasks, general well-being, occupational health and safety, cannabis use, and tobacco use. Colorado cannabis workers were generally job secure and valued safety. However, they regularly consumed cannabis, expressed low concerns about workplace hazards, reported some occupational injuries and exposures, and reported inconsistent training practices. Working in the cannabis industry is associated with positive outcomes for workers and their organizations, but there is an imminent need to establish formal health and safety training to implement best practices. © 2018 Wiley Periodicals, Inc.

Data on the economic consequences of occupational injuries is scarce in developing countries which prevents the recognition of their economic and social consequences. This study assess the direct heath care costs of work-related accidents in the Mexican Institute of Social Security, the largest health care institution in Latin America, which covered 12,735,856 workers and their families in 2005. We estimated the cost of treatment for 295,594 officially reported occupational injuries nation wide. A group of medical experts devised treatment algorithms to quantify resource utilization for occupational injuries to which unit costs were applied. Total costs were estimated as the product of the cost per illness and the severity weighted incidence of occupational accidents. Occupational injury rate was 2.9 per 100 workers. Average medical care cost per case was $2,059 USD. The total cost of the health care of officially recognized injured workers was $753,420,222 USD. If injury rate is corrected for underreporting, the cost for formal injured workers is 791,216,460. If the same costs are applied for informal workers, approximately half of the working population in Mexico, the cost of healthcare for occupational injuries is about 1% of the gross domestic product. Health care costs of occupational accidents are similar to the economic direct expenditures to compensate death and disability in the social security system in Mexico. However, indirect costs might be as important as direct costs.

Work fulfills personal values, perhaps differently for males and females. Explored here was the role values play in shaping occupational interests. Study 1 examined children's, adolescents', and adults' (N = 313) occupational values (regarding money, power, family, altruism), occupational interests, and perceptions of values afforded by traditionally masculine and feminine occupations. Results revealed sex differences in occupational values and interests. Furthermore, participants' values predicted their own interests in culturally masculine and feminine occupations. Study 2 used novel jobs and experimentally manipulated prototypical sex of worker and value affordances to disentangle their effects on occupational interests. At all ages, participants' (N = 240) occupational interests were affected by the depicted sex of the workers and by the stated value affordances of the jobs.

The deltaE between restorations and natural teeth as referenced were analyzed. And satisfaction of dentists and patients were evaluated. The deltaE between metal-ceram restorations and natural teeth was 7.13 +/- 0.74. The deltaE between foundry-ceram restorations and teeth was 1.47 +/- 0.84. There were statistical differences between the deltaE (P < 0.01). The satisnatural faction of dentists and patients to the foundry-ceram restorations were higher than to the metal-ceram restorations (P < 0.05). Crystaleye spectrophotometer can provide accurate reference for foundry-ceram restoration, but for metal-ceram restoration it is not accurate.

To estimate the lifetime and 12-month prevalence of occupational exposure to body fluids among health-care workers in Africa. Embase®, PubMed® and CINAHL databases were systematically searched for studies published between January 2000 and August 2017 that reported the prevalence of occupational exposure to blood or other body fluids among health-care workers in Africa. The continent-wide prevalence of exposure was estimated using random-effects meta-analysis. Of the 904 articles identified, 65 studies from 21 African countries were included. The estimated pooled lifetime and 12-month prevalence of occupational exposure to body fluids were 65.7% (95% confidence interval, CI: 59.7-71.6) and 48.0% (95% CI: 40.7-55.3), respectively. Exposure was largely due to percutaneous injury, which had an estimated 12-month prevalence of 36.0% (95% CI: 31.2-40.8). The pooled 12-month prevalence of occupational exposure among medical doctors (excluding surgeons), nurses (including midwives and nursing assistants) and laboratory staff (including laboratory technicians) was 46.6% (95% CI: 33.5-59.7), 44.6% (95% CI: 34.1-55.0) and 34.3% (95% CI: 21.8-46.7), respectively. The risk of exposure was higher among health-care workers with no training on infection prevention and those who worked more than 40 hours per week. The evidence available suggests that almost one half of health-care workers in Africa were occupationally exposed to body fluids annually. However, a lack of data from some countries was a major limitation. National governments and health-care institutions across Africa should prioritize efforts to minimize occupational exposure among health-care workers.

Methods: A total of 728 workers in a petroleum processing enterprise at an altitude of 2850 m were subjected to a survey using Occupational Stress Inventory (OSI) , Work Ability Index (WAI) Scale, Occupational Role Questionnaire (ORQ) , Personal Strain Questionnaire (PSQ) , and Personal Resource Questionnaire (PRQ) from May 2014 to August 2016. Results: Of the 728 workers, 55 (7.6%) had a poor working ability, moderate in 262 (35.9%) , and good in 411 (56.5%). There were significant differences in WAI between the workers with different types of work, sexes, ages, and working years ( P <0.05). There was a significant difference in WAI between different occupational stress groups ( P <0.05). WAI was negatively correlated with ORQ score and PSQ score ( r (s)=-0.387, P <0.05; r (s)=-0.467, P <0.05) and positively correlated with PRQ score ( r (s)=0.343, P <0.05). The multiple linear regression analysis showed that high ORQ score and PSQ score were the inhibitory factors for high WAI ( B =-0.058; B =-0.082) and high PRQ score was a contributing factor for high WAI ( B =0.029) . Conclusion: Occupational stress is an influencing factor for the working ability of workers in the petroleum processing enterprise in the high altitude area. Hypoxia in high altitude area may further reduce the working ability. In order to reduce occupational stress and improve work ability, it should be considered to strengthen skills training, improve the working environment, and pay attention to mental health.

Spectrum of high-resolution computed tomography imaging in occupational lung disease

Damage to the lungs caused by dusts or fumes or noxious substances inhaled by workers in certain specific occupation is known as occupational lung disease. Recognition of occupational lung disease is especially important not only for the primary worker, but also because of the implications with regard to primary and secondary disease prevention in the exposed co-workers. Although many of the disorders can be detected on chest radiography, high-resolution computed tomography (HRCT) is superior in delineating the lung architecture and depicting pathology. The characteristic radiological features suggest the correct diagnosis in some, whereas a combination of clinical features, occupational history, and radiological findings is essential in establishing the diagnosis in others. In the presence of a history of exposure and consistent clinical features, the diagnosis of even an uncommon occupational lung disease can be suggested by the characteristic described HRCT findings. In this article, we briefly review the HRCT appearance of a wide spectrum of occupational lung diseases. PMID:24604929

The aim of this study was to describe outdoor workers' sun-protective practices, workplace sun-safety culture and sun-protective equipment provision; investigate the association of demographic, personal and occupational factors with sun-protective practices; and identify potential strategies for improving workers' sun protection. The present study used a clustered survey design with randomly identified employers in nine occupations. Employees provided questionnaire measures of demographics, personal characteristics (skin type, skin cancer risk perceptions, tanning attitudes, sun-exposure knowledge), personal occupational sun protection practices (exposure reduction, use of sun-protective clothing, sunscreen and shade), workplace sun-protective equipment provision and perceived workplace sun-safety culture. Summative scores were calculated for attitudes, knowledge, workplace provision and culture. A multivariable model was built with worker and workplace variables as plausible predictors of personal sun protection. In this study, 1,061 workers (69% participation) from 112 workplaces provided sufficient information for analysis. Sex, age, prioritized ethnicity, education and risk perception differed significantly between occupational groups (p<0.001), as did workers' sun-protective practices and workplace sun-protection equipment provision and supportive culture. After adjustment, each one-point increase in Workplace Sun-safety Culture 2013Score (range 12 points) was associated with a 0.16 higher Personal Sun-Protection Score (p<0.001), and each one-point increase in Workplace Provision Score (range 4 points) was associated with a 0.14 higher score (p<0.001). Sun Protection Score was significantly associated with skin response to sun exposure (p<0.001), female sex (p=0.021), tanning attitudes (p=0.022) and occupation (p=0.049), but not ethnicity, age education, knowledge or skin cancer risk perception. Protective equipment provision and sun-protective workplace culture are promising components for the development of comprehensive programmes to improve outdoor workers' sun-protective practices.

Prolonged sitting is a health risk for cardiovascular diseases and all-cause mortality, independent of moderate-to-vigorous physical activity. Epidemiological evaluation of occupational sitting has received little attention, even though it may have a potential impact on workers' health. We prospectively examined the association between occupational sitting time and all-cause mortality. Community-dwelling, Japanese workers aged 50-74 years who responded to a questionnaire in 2000-2003 were followed for all-cause mortality through 2011. Cox proportional hazard models were employed to calculate hazard ratios (HR) of all-cause mortality among middle (1- to <3 hours/day) or longer (≥3 hours/day) occupationally sedentary subjects by gender or types of engaging industry ("primary industry" and "secondary or tertiary industry"). During 368,120 person-years of follow-up (average follow-up period, 10.1 years) for the 36,516 subjects, 2209 deaths were identified. Among workers in primary industry, longer duration of occupational sitting was significantly or marginally associated with higher mortality [HR 1.23, 95% confidence interval (95% CI) 1.00-1.51 among men; HR 1.34, 95% CI 0.97-1.84 among women]. No associations were found among secondary or tertiary industry workers (men: HR 0.87, 95% CI 0.75-1.01; women: HR 1.03, 95% CI 0.77-1.39). Occupational sitting time increased all-cause mortality among primary industry workers, however similar relationships were not observed for secondary-tertiary workers. Future studies are needed to confirm detailed dose-response relationships by using objective measures. In addition, studies using cause-specific mortality data would be important to clarify the physiological underlying mechanism.

Occupational skin diseases (OSDs) represent 10-40% of all occupational diseases in many industrialized countries. Young workers are frequently exposed to toxic substances and chemicals in the workplace. The occupational conditions of young workers can impose a high level of risk for the occurrence of OSDs. The Nordic Occupational Skin Questionnaire (NOSQ-2002) was developed in English as a new, comprehensive, standardized tool with which to screen for OSDs. The purpose of this study was to translate the NOSQ-2002 into Turkish and to culturally adapt the long version of the instrument for use with young workers in jobs with high risk for the occurrence of OSDs. Forward and back translations were carried out. Problematic items were modified until the Turkish-language version achieved a satisfactory consensus with the original version of the NOSQ-2002. The final Turkish version was tested in 40 randomly selected young workers with and without OSDs who were studying in the fields of hairdressing, jewelry making, and car mechanics at vocational training schools run by the National Education Ministry. When the original questionnaire had been translated into the target language, a first consensus version was evaluated by an expert panel. The expert panel determined that 36 questions (63.2%) in the Turkish version required some level of modification in order to facilitate clear understanding. Cognitive interviews were then performed. After some modification, the final Turkish version was established and tested among young workers. The new Turkish version of the NOSQ is a comprehensible, reliable, and useful tool that can be applied to young workers in specific occupations. © 2015 The International Society of Dermatology.

Introduction Injury rate among mining workers in Zimbabwe was 789/1000 workers in 2008. The proportion of severe occupational injuries increased from 18% in 2008 to 37% in 2009. We investigated factors associated with severe injuries at the mine. Methods An unmatched 1:1 case-control study was carried out at the mine, a case was any worker who suffered severe occupational injury at the mine and was treated at the mine or district hospital from January 2008 to April 2010, a control was any worker who did not suffer occupational injury during same period. We randomly selected 156 cases and 156 controls and used interviewer administered questionnaires to collect data from participants. Results Majority of cases, 155(99.4%) and of controls 142(91%) were male, 127(81.4%) of cases and 48(30.8%) of controls worked underground. Majority (73.1%) of severe occupational injuries occurred during night shift. Underground temperatures reached 500C. Factors independently associated with getting severe occupational injuries included working underground (AOR = 10.55; CI 5.97-18.65), having targets per shift (AOR = 12.60; CI 3.46-45.84), inadequate PPE (AOR= 3.65 CI 1.34-9.89) and working more than 8 hours per shift (AOR = 8.65 CI 2.99-25.02). Conclusion Having targets exerts pressure to perform on workers. Prolonged working periods decrease workers’ attention and concentration resulting in increased risk to severe injuries as workers become exhausted, lose focus and alertness. Underground work environment had environmental hazards so managers to install adequate ventilation and provide adequate PPE. Management agreed to standardize shifts to eight hours and workers in some departments have been supplied with adequate PPE. PMID:23504270

Workers are exposed to potential irritants and allergens with constant introduction of new industrial chemicals in the workplace. Characterize the final diagnoses, demographics, occupations, exposures, clinical presentations, patch test results, dermatologic histories, and risk factors of workers evaluated for suspected work-related allergic contact dermatitis (ACD). A retrospective chart review of 310 workers' compensation independent medical examinations evaluated for suspected work-related ACD was performed. Workers were seen in a community dermatology clinic in Portland, Oregon, from 2005 to 2014. Evaluation included history, physical examination, patch testing, and further diagnostic workup when indicated. Hand dermatitis was the most common presentation (n = 148, 47.7%). Prevalent occupations included health care workers (n = 51, 16.5%), custodial staff (n = 41, 13.2%), and machinists (n = 36, 11.6%). Allergic contact dermatitis (47.5%) was more common than irritant contact dermatitis (ICD) (38.9%) in those diagnosed as having occupational skin disease (n = 185). The highest-frequency work-related allergens were thiuram mix (21 of 88, 23.9%), carba mix (20 of 88, 22.7%), potassium dichromate (9 of 88, 10.2%), and epoxy resin (9 of 88, 10.2%). Allergic contact dermatitis and ICD are common occupational skin disorders. In this population of workers' compensation referrals, ACD was more common, with 73.3% of those cases work related, compared with 86.7% of ICD. Blue collar work and wet work were risk factors for the development of ACD and ICD.

To investigate the relationship between occupational stress and mental health in offshore oil platform workers and to provide a scientific basis for protection of their mental health. A total of 768 workers on offshore oil platform were surveyed with the Occupational Stress Inventory Revised Edition and Symptom Check List-90 (SCL-90). The total score of Occupational Role Questionnaire (ORQ) for the workers (160.27±24.63) was significantly lower than the national norm (166.52±27.01) (P < 0.01); the total score of Personal Strain Questionnaire (PSQ) (101.96±19.8) was significantly higher than the national norm (92.45±17.33) (P < 0.01). The total score of Personal Resource Questionnaire (PRQ) for the workers was not significantly different from the national norm (P > 0.05), but the items of recreation, social support, and rational/cognitive found significant difference (P < 0.05). The total score of SCL-90 was positively correlated with all items of ORQ and PSQ (P < 0.01) and negatively correlated with all items of PRQ (P < 0.01). The multiple stepwise regression analysis showed that current work seniority, education background, drinking, role overload, role insufficiency, role ambiguity, responsibility, physical environment, and rational/cognitive conduct impacted the score of SCL-90 (P < 0.05). The mental health of workers on offshore oil platform is related to occupational stress, and role overload, role ambiguity, physical environment, and rational/cognitive conduct, etc, are closely associated with the workers' mental health.

Objectives The prevalence of the metabolic syndrome has increased rapidly in South Korea over the past 10 years. However, the occurrence of the metabolic syndrome in workers grouped according to the specific type of work is not well understood in Korea. In this study, we assessed the differences in the prevalence of the metabolic syndrome by occupational group and evaluated the risk of the metabolic syndrome among occupational groups. Methods From the Fifth Korean National Health and Nutrition Examination Survey (2010), 3,303 employed participants were included in this study. The unadjusted and age-adjusted prevalences of the metabolic syndrome were estimated and multiple logistic regression analysis was conducted using the presence of the metabolic syndrome as a dependent variable, and adjusting for age, education level, household income, drinking behavior, smoking status, physical activity, work hours, and work scheduling pattern. Results Among male workers, non-manual workers had the greatest age-adjusted prevalence (26.4%, 95% CI: 22.3-30.5%) among the occupational groups. In a logistic regression analysis, male manual workers had a significantly lower odds ratio for the metabolic syndrome relative to non-manual workers (0.59, 95% CI: 0.41-0.85). Conclusion Our study demonstrated differences in the prevalence of the metabolic syndrome by occupational group and identified the greatest risk for the metabolic syndrome in male non-manual workers.

Total Worker Health™ is defined as a "strategy integrating occupational safety and health protection with health promotion to prevent worker injury and illness and to advance worker health and well-being." This strategy aligns workplace safety with individual behaviors that support healthy lifestyles. The Patient Protection and Affordable Care Act of 2010 presumes that incentive-oriented worksite health promotion provides a critical pathway to reduce group health costs. Because of their scientific and clinical backgrounds, professional nurses are well qualified to educate and assist individuals with healthy lifestyle choices. Occupational health nurses and patient advocates can shape wellness initiatives that best serve both employees and their employers. © 2015 The Author(s).

The high rates of injury among young workers are a pressing public health issue, especially given the demand of the job market for new workers. Young and new workers experience the highest rates of occupational injuries of any age group. Incorporating occupational safety and health (OSH) information into the more than 20 000 vocational and other workforce preparation programs in the United States might provide a mechanism for reducing work-related injuries and illnesses among young and new workers. We assessed the status of including OSH information or training in workforce preparation programs and found there is an inconsistent emphasis on OSH information. PMID:15727967

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.

To investigate the occupational health of the workers simultaneously exposed to acrylonitrile, epoxyethane, epoxypropane, and styrene. A questionnaire survey was conducted in 70 front-line workers simultaneously exposed to acrylonitrile, epoxyethane, epoxypropane, and styrene (exposure group) and 50 managers (control group) in a polyether manufacturer; in addition, air monitoring at workplace and occupational health examination were also performed. The obtained data were analyzed. The female workers in exposure group and the spouses of male workers in exposure group had significantly higher spontaneous abortion rates than their counterparts in control group (P < 0.01). The exposure group had a significantly higher abnormal rate of blood urea nitrogen than the control group (P < 0.01). The workers with different polyether-exposed working years had significantly higher mean levels of DNA damage than the control group (P < 0.01); the workers with not less than 5 and less than 20 polyether-exposed working years and those with not less than 20 polyether-exposed working years had significantly higher mean micronucleus rates than the control group (P < 0.01); there were no significant differences in overall chromosome aberration rate and mean level of DNA damage between each two groups of workers with different polyether-exposed working years (P > 0.05); the workers with not less than 5 and less than 20 polyether-exposed working years and workers with not less than 20 polyether-exposed working years had significantly higher mean micronucleus rates than those with less than 5 polyether-exposed working years (P < 0.01). Simultaneous exposure to acrylonitrile, epoxyethane, epoxypropane, and styrene causes occupational hazards among the workers in polyether manufacturer.

Construction workers are at increased risk of work-related ill-health (WRI) worldwide. To compare the incidence of medically reported WRI in occupations within the UK construction industry according to job title. We calculated standardized incidence rate ratios (SRRs) using WRI cases for individual job titles returned to The Health and Occupation Reporting network by clinical specialists and UK population denominators. We counted frequencies of reported causal exposures or tasks reported by clinical specialists, occupational physicians and general practitioners. We found significantly increased incidence of WRI compared with other workers in the same major Standard Occupational Classification, i.e. workers with similar levels of qualifications, training, skills and experience, for skin neoplasia in roofers (SRR 6.3; 95% CI: 3.1-13.1), painters and decorators (2.1; 95% CI: 1.2-3.6) and labourers in building and woodworking trades (labourers, 6.6; 95% CI: 3.2-13.2); contact dermatitis in metal workers (1.4; 95% CI: 1.1-1.7) and labourers (1.6; 95% CI: 1.1-2.3); asthma in welders (3.8; 95% CI: 2.8-5.0); musculoskeletal disorders in welders (1.7; 95% CI: 1.1-2.8), road construction operatives (6.1; 95% CI: 3.8-9.6) and labourers (2.5; 95% CI: 1.7-3.7); long latency respiratory disease (mesothelioma, pneumoconiosis, lung cancer, non-malignant pleural disease) in pipe fitters (4.5; 95% CI: 3.2-6.2), electrical workers (2.7; 95% CI: 2.4-3.2), plumbing and heating engineers (2.3; 95% CI: 1.9-2.7), carpenters and joiners (2.7; 95% CI: 2.3-3.1), scaffolders (12; 95% CI: 8-18) and labourers (3.3; 95% CI: 2.6-4.1). UK construction industry workers have significantly increased risk of WRI. These data in individual construction occupations can be used to inform appropriate targeting of occupational health resources.

2018-03-06

There is a considerable gap in epidemiological literature about community mental health showing how psychiatric symptoms are associated with job rank, socioeconomic status, and occupational health. We examine data from 4596 employees collected in the United Kingdom's Psychiatric Morbidity among Adults Living in Private Households Survey. There were 939 workers in managerial jobs, 739 in supervisory jobs and 2918 employees in lower ranking jobs. Of the 4596 workers, 2463 had depressive symptoms and 2133 no depressive symptoms. Job rank, household gross income, social class, personal gross income and socio-economic group were significantly associated with general health, occupational health and depressive and avoidant symptoms. Job rank, occupational and physical health also explained the variance in paranoid and avoidant symptoms among the employees. This study shows that severe psychopathology is related to workers' job rank.

High-risk occupations for women exposed to cadmium.

PubMed

Freeman, C S

1994-08-01

Occupational exposures to cadmium are associated with increased risk of lung cancer and renal disease. The Occupational Safety and Health Administration (OSHA) published two standards for cadmium on September 14, 1992 that reduced the permissible occupational exposure limit. In the cadmium industry, women were less likely to be exposed to high levels of cadmium and more likely to hold job titles containing the word "hand" than were men. Only small numbers of female workers were exposed to any level of cadmium. OSHA's risk assessment relied, in part, on morbidity and mortality data from male workers and in part on rodent (animal) data from both sexes. OSHA did not evaluate illness rates specific to female workers. Several factors may alter the risk of these illnesses and their sequelae among workers, including differences in smoking, route of exposures, ability to wear personal protective equipment, and lifestyle.

More immigrants are seeking employment in restaurants. Drawing data from an ethnographic study, this article discusses what and how sociocultural contexts shape the safety and health of immigrant restaurant workers. Eighteen Chinese immigrants from China, Hong Kong, and Taiwan participated in the study. Data generation methods included a questionnaire, individual and focus group interviews, and participant observations. Ethnographic analysis revealed that immigration mechanisms, demands of English proficiency for employment, and existence of networks and ethnic communities shaped the participants' employment choices. Working hours and schedules, interpersonal relationships at work, job design and training, occupational safety and health training, and national events and economy further influenced the participants' occupational experiences and well-being. Issues were noted with job security, mental health, family relationships, and risks for occupational injuries and illnesses. Implications for occupational health nursing research and practice to reduce immigrant workers' vulnerability to poor safety and health outcomes conclude this article.

A cohort of Washington State workers with wage-replacement benefits for back injuries completed baseline and 1-year follow-up telephone interviews. We obtained additional measures from claims and medical records. Among 1263 workers, 174 (13.8%) reported clinically significant weight gain (≥7%) 1 year after occupational back injury. Women and workers who had more than 180 days on wage replacement at 1 year were twice as likely (adjusted odds ratio = 2.17, 95% confidence interval = 1.54 to 3.07; adjusted odds ratio = 2.40, 95% confidence interval = 1.63 to 3.53, respectively; both P < 0.001) to have clinically significant weight gain. Women and workers on wage replacement for more than 180 days may be susceptible to clinically significant weight gain after occupational back injury.

Management system of occupational diseases in Korea: statistics, report and monitoring system.

PubMed

Rhee, Kyung Yong; Choe, Seong Weon

2010-12-01

The management system of occupational diseases in Korea can be assessed from the perspective of a surveillance system. Workers' compensation insurance reports are used to produce official statistics on occupational diseases in Korea. National working conditions surveys are used to monitor the magnitude of work-related symptoms and signs in the labor force. A health examination program was introduced to detect occupational diseases through both selective and mass screening programs. The Working Environment Measurement Institution assesses workers' exposure to hazards in the workplace. Government regulates that the employer should do health examinations and working conditions measurement through contracted private agencies and following the Occupational Safety and Health Act. It is hoped that these institutions may be able to effectively detect and monitor occupational diseases and hazards in the workplace. In view of this, the occupational management system in Korea is well designed, except for the national survey system. In the future, national surveys for detection of hazards and ill-health outcomes in workers should be developed. The existing surveillance system for occupational disease can be improved by providing more refined information through statistical analysis of surveillance data.

Objective: To investigate hearing loss status of blasters, drillers mechanics and so on in underground mining, and put forward suggestion diagnosis of occupational explosive deafness and occupational deafness. Methods: Underground excavation workers in a metal mine were recruited in this study, those with a history of ear disease and non-occupational deafness were all excluded. Finally, the features of pure tone audiometry of 459 noise-exposed workers were analyzed. Results: High-frequency hearing loss occurred on 351workers and the positive detection rate was 74.29%, workers who had both high-frequency and linguistic frequency hearing loss were 51 and the positive detection rate was 11.11%. The positive detection of high-frequency hearing loss in right ear (χ(2)=9.427 and P = 0.024) and in left ear (χ(2)=14.375, P =0.002) was significantly different between different exposure age groups. The positive detection of high-frequency hearing loss of driving group was the highest, followed by blasting group, mining group and machine repair group. The characteristics of the hearing loss caused by drilling noise of the blasting workers with no accident occurred were in line with that of noise-induced hearing loss. Conclusion: The diagnosis grading should be carried out according to the diagnostic criteria of occupational noise-induced deafness for the employees who engaged in the blasting operation with no record of blast accident.

The role of occupational hazards in occupational injury may be mediated by individual factors across various age groups. This study assessed the role of occupational hazards as well as contribution of individual factors to injuries among Indian and French coalminers. We conducted a case-control study on 245 injured workers and on 330 controls without any injuries from Indian coal mines using face-to-face interviews, and a retrospective study on 516 French coalminers using a self-administered questionnaire including potential occupational and personal factors. Data were analyzed using logistic models. The annual rate of injuries was 5.5% for Indian coalminers and 14.9% for the French ones. Logistic model including all occupational factors showed that major injury causes were: hand-tools, material handling, machines, and environment/work-geological/strata conditions among Indian miners (adjusted odds-ratios 2.01 to 3.30) and biomechanical exposure score among French miners (adjusted odds-ratio 3.01 for score the 1-4, 3.47 for the score 5-7, and 7.26 for score ≥ 8, vs. score 0). Personal factors among Indian and French coalminers reduced/exacerbated the roles of various occupational hazards to a different extent depending on workers' age. We conclude that injury roles of occupational hazards were reduced or exacerbated by personal factors depending on workers' age in both populations. This knowledge is useful when designing prevention which should definitely consider workers' age.

The purpose of this study was to analyze a participatory approach to occupational safety and health, and to examine the possibility of applying the concept to the practice and research of occupational safety and health. According to Rodger's method, descriptive data concerning antecedents, attributes and consequences were qualitatively analyzed. A total of 39 articles were selected for analysis. Attributes with a participatory approach were: "active involvement of both workers and employers", "focusing on action-oriented low-cost and multiple area improvements based on good practices", "the process of emphasis on consensus building", and "utilization of a local network". Antecedents of the participatory approach were classified as: "existing risks at the workplace", "difficulty of occupational safety and health activities", "characteristics of the workplace and workers", and "needs for the workplace". The derived consequences were: "promoting occupational safety and health activities", "emphasis of self-management", "creation of safety and healthy workplace", and "contributing to promotion of quality of life and productivity". A participatory approach in occupational safety and health is defined as, the process of emphasis on consensus building to promote occupational safety and health activities with emphasis on self-management, which focuses on action-oriented low-cost and multiple area improvements based on good practices with active involvement of both workers and employers through utilization of local networks. We recommend that the role of the occupational health professional be clarified and an evaluation framework be established for the participatory approach to promote occupational safety and health activities by involving both workers and employers.

We attempted to explore the relationship between working hours and sleep disturbance according to occupation and gender among Korean workers. Data were derived from the third Korean Working Conditions Survey, conducted in 2011 by the Korea Occupational Safety and Health Agency. From a total of 50,032 workers, 34,783 salaried contract workers were selected. Work hours were categorized as <40, 40-48 (reference), 49-60, and >60 h/week. The outcome variable was sleep disturbance, which was assessed by a single question item (During the past 12 months, have you experienced sleep disturbance or insomnia?). Multiple survey logistic regression models were performed after adjusting with age, education level, marital status, self-rated health, salary, shift work, smoking and alcohol drinking. Gender and occupation were stratified in these models. The adjusted odds ratio (OR) for sleep disturbance in male non-manual workers with long work hours (>60 h/week) was 3.017 [95% confidence interval (CI) 1.956-4.653]. In female non-manual workers who work 49-60 working hour per week, the OR was 1.525 (95% CI 1.034-2.249). Long working hours can be a risk factor for sleep disturbance in Korean workers. The association was especially prominent in male non-manual workers.

The aim of this work is to analyse the prevalence of occupational diseases in construction industry, comparing the results of the first years of health surveillance (1996-2000) and today's situation. We compare the prevalence of occupational diseases observed in 1348 workers during the period 1996-2000 (mean age 36,4 years, DS 11,8; mean experience in construction industry 16,9 years, DS 12,3) and the one observed in 795 different workers during 2006 (mean age 38,8 years, DS 11,1; mean experience in construction industry 18 years, DS 16,6). The prevalence of occupational diseases is respectively 12.09% and 12.83%. But analysing the single pathology it's possible to observe important differences between the two groups. In the workers observed in 2006 there is a significant reduction in prevalence of hearing loss caused by chronic exposure to noise and in prevalence of vascular disease caused by hand-arm vibrations: respectively from 94,9 to 79,2 cases/1000 workers and from 6,7 to 2.6 cases/1000 workers. Musculoskeletal diseases instead are increased from 11,1 to 37,7 cases/1000 workers, showing more attention to the problem, better diagnostics ability and more recognition by public insurance agency for occupational diseases.

2013-08-01

There is widespread agreement that work organization is an important element of occupational safety and health, but the health effects of many aspects of work organization are likely to vary considerably across different sectors of work and geographies. We examined existing employment policies and work organization-related research relevant specifically to immigrant workers in the Agriculture, Forestry, and Fishing (AgFF) Sector of the US workforce focusing, when possible, on the southeastern US. A number of specific aspects of work organization within AgFF subsectors have been described, but most of this literature exists outside the purview of occupational health. There are few studies that directly examine how attributes of work organization relevant to the AgFF Sector affect workers', much less immigrant workers', occupational health exposures and outcomes. In contrast to the broader literature, research linking occupational health outcomes to work organization in the AgFF Sector is limited and weak. A systematic program of research and intervention is needed to develop strategies that eliminate or substantially mitigate the deleterious health effects of occupational exposures whose origins likely lie in the organization of AgFF work.

There is little published about the role of individual characteristics in occupational injuries. Construction workers have a high rate of injury; we assessed 11 personal characteristics in this professional sector. A case-control study was conducted on 880 male workers who had had at least one occupational injury during a 2-year period and 880 controls. A questionnaire was administered by an occupational physician. Statistical analysis was made via logistic regression method. Young age (<30 years), sleep disorders and current smoker influenced all the injuries combined. Sleep disorders and young age were common risk factors for several jobs. Physical disabilities and no sporting activity had a role in masons, and 5 years or less in present job in plumbers and electricians only. Sleep disorders influenced both the injuries with and without hospitalization; young age, current smoker, and physical disability influenced those without hospitalization only. Young age, sleep disorders, smoking, disabilities, sporting activity, and experience influenced the occupational injuries. The risk for each worker depended on his job. Occupational physicians could inform the workers of these risks and encourage them to take remedial action. Copyright 2003 Wiley-Liss, Inc.

Occupational ultraviolet radiation (UVR) exposure is a risk factor for skin cancer, and Hispanic individuals are over-represented in a number of outdoor occupations (e.g., farming, landscaping). This study examined predictors of occupational sunscreen use in a group of US Hispanic adults who work outdoors. A population-based sample of outdoor workers (n = 149, 85 % male) completed survey measures regarding their demographics, melanoma risk, perceived skin cancer risk, skin cancer knowledge, and their occupational sunscreen use. Sixty-nine percent of the sample reported never or rarely wearing sunscreen while working outdoors. Being female (p = .02), having a higher level of education (p = .03), and residing at a higher latitude (p = .04) were associated with more frequent sunscreen use. This study highlights the importance of interventions to promote sun protection behaviors among US Hispanic outdoor workers, and identifies potential intervention targets.

What's So Special about STEM? A Comparison of Women's Retention in STEM and Professional Occupations.

We follow female college graduates in the National Longitudinal Survey of Youth 1979 and compare the trajectories of women in science, technology, engineering, and mathematics (STEM)-related occupations to other professional occupations. Results show that women in STEM occupations are significantly more likely to leave their occupational field than professional women, especially early in their career, while few women in either group leave jobs to exit the labor force. Family factors cannot account for the differential loss of STEM workers compared to other professional workers. Few differences in job characteristics emerge either, so these cannot account for the disproportionate loss of STEM workers. What does emerge is that investments and job rewards that generally stimulate field commitment, such as advanced training and high job satisfaction, fail to build commitment among women in STEM.

Vinyl chloride monomer (VCM) is widely used in the production of polyvinyl chloride (PVC) plastics. VCM is recognized as a confirmed human and animal carcinogenic compound. Recent studies have reported poor health of plastic workers, even having exposure at concentrations below the permissible limit to VCM. There has not been any study regarding exposed workers to VCM in Iran. Similarly, no information exists as to the biological monitoring of such workers. The main purpose of this study was to conduct a thorough occupational and biological monitoring of Iranian plastic workers exposed to VCM.A total of 100 workers from two plastic manufacturing plants (A and B) in Tehran along with 25 unexposed workers as controls were studied. The personal monitoring of all nonsmoking workers exposed to VCM at two plastic manufacturing plants (A and B) was performed in the morning shift (8 a.m. to 4 p.m.) according to the National Institute For Occupational Safety And Health method no. 1007.Biological monitoring of workers was carried out through collection of exhaled breath of all exposed and control workers in Tedlar bags and with a subsequent analysis using gas chromatography-flame ionization detector.Not only the mean occupational exposure of workers to VCM at plant A was higher than the respective threshold limit value but also the statistical significance was higher than workers at plant B. Similarly, VCM concentration in exhaled breath of workers at plant A was also statistically significantly higher than at plant B. Correlation of occupational exposure of all workers to vinyl chloride with its concentration in exhaled breath was statistically significant.This is the first study on biological monitoring for exposed plastic workers to VCM using exhaled breath. On the basis of the results in this study, a novel method of biological monitoring of plastic workers was proposed. © The Author(s) 2015.

A survey using a questionaire was conducted to elucidate the employment conditions and a system of occupational health administration status of the disabled workers in private enterprises. The average employment rate of disabled workers was found to be higher in small-scale enterprises, than in large-scale enterprises. Also, the low employment rate was found among cases of spinal cord injuries and hemipregia. The reasons for workers becoming disabled were "private accident and illness" (59.2%) "congenital" (30.6%) and "labor accident" (10.2%). The main physical factor influencing work efficiency of disabled workers was "degree of disability" while "work morale" was found to be the most influential psychological factor. Also it was found that about 50% of private enterprises will accept the reinstatement and employment of spinal cord injury or hemipregia workers. But it will be necessary that the disabled workers are able to do the requested job. However, it is necessary for employers of disabled workers to make various efforts in overcoming situations such as, changes in organization, improvement of occupational health administration staffs and improvements in the working environment and equipment.

[Prevention of occupational solar UV radiation-induced epithelial skin cancer].

2015-03-01

Malignancies of the skin, with an incidence of more than 200,000 newly registered cases/year, are the most frequently notified malignances in Germany. In Europe, squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) account for about 30 cases/100,000 persons and 50-100 cases/100,000 persons, respectively. Ultraviolet (UV) exposure is the main risk factor to induce these cancers. Increased incidence rates were shown for persons having red/blonde hair as well as light eye colour, acquire sun burns easily, hardly tan and develop freckles. The majority of the malignancies and precursor lesions are acquired by UV exposure in leisure time. However, in highly occupationally UV-exposed outdoor workers, UV monitoring revealed that exposure levels are 2-3 times higher compared to the general population. Occupations likely to be highly exposed are farmers, forestry workers, gardeners, landscapers, fishermen and seafarers, construction workers, builders, tin smiths, sport teachers, mountain guides, etc. Recent metaanalyses showed that occupational UV exposure is a relevant and independent risk factor for SCC and to a lesser extent also for BCC. To prevent occupationally caused malignancies of the skin a significant reduction of occupationally acquired UV dosages in outdoor workers is mandatory. Relevant factors influencing the cumulative sun exposure in outdoor workers are the amount of UV exposure, the specific tasks to be performed in the sun as well as the UV protection habits of the workers. Besides adequate behavior, textile protection by headgear and clothing as well as the regular use of sunscreens and sun glasses are important.

Five metal turners employed by an aerospace manufacturer presented to the Birmingham Chest Clinic occupational lung disease unit. Four cases of occupational asthma (OA) due to chromium salt (3) and cobalt (1) were diagnosed by serial peak-expiratory flow measurements and specific inhalation challenge testing. To measure the extent of the outbreak and to provide epidemiological data to ascertain the aetiology. Participants answered a detailed, self-administered questionnaire, designed to detect occupational lung disease. Urine chromium and cobalt excretion, spirometry and exhaled nitric oxide measurements were taken. Those with possible, probable or definite non-OA or OA, after questionnaire, were invited to undertake two-hourly peak flow measurements and received specialist follow-up. A total of 62 workers (95% of workforce) participated. Sixty-one per cent of employees were working in higher metalworking fluid (MWF) exposure areas. Ninety per cent of workers had urinary chromium excretion indicating occupational exposure. Sixty-six per cent of workers reported active respiratory symptoms, although there were no significant differences between exposure groups. Two further workers with probable OA were identified and had significantly higher urinary chromium and cobalt concentration than asymptomatic controls. Eighteen cases of occupational rhinitis (OR) were identified, with significantly raised urinary chromium concentration compared with asymptomatic controls. Chromium salt and cobalt can be responsible for OA and OR in workers exposed to MWF aerosols. Onset of symptoms in those with positive specific challenges followed change in MWF brand. Workers with OA had increased urinary concentrations of chromium and cobalt, and those with OR had increased urinary concentrations of chromium.

This research aimed to determine the prevalence of workplace violence (WPV) against healthcare workers, explore the frequency distribution of violence in different occupational groups, and determine which healthcare occupation suffers from WPV most frequently. Furthermore, the current study aimed to compare risk factors affecting different types of WPV in Chinese hospitals. A cross-sectional design was utilized. A total of 1899 healthcare workers from Heilongjiang, a province in Northeastern China, completed the questionnaire. Of the respondents, 83.3% reported exposure to workplace violence, and 68.9% reported non-physical violence. Gender, education, shift work, anxiety level, and occupation were significantly correlated with physical violence ( p < 0.05 for all correlations). Additionally, age, professional title, and occupation were correlated with non-physical violence, which critically affected doctors. Thus, gender, age, profession, anxiety, and shift work were predictive of workplace violence toward healthcare workers. Doctors appeared to experience non-physical workplace violence with particularly higher frequency when compared to nurses and other workers in hospitals. For healthcare workers, interventions aimed at WPV reduction should be enacted according to the types of violence, profession, and other factors underlying the various types of WPV in hospitals.

The Impact of Physical and Ergonomic Hazards on Poultry Abattoir Processing Workers: A Review.

PubMed

Harmse, Johannes L; Engelbrecht, Jacobus C; Bekker, Johan L

2016-02-06

The poultry abattoir industry continues to grow and contribute significantly to the gross domestic product in many countries. The industry expects working shifts of eight to eleven hours, during which workers are exposed to occupational hazards which include physical hazards ranging from noise, vibration, exposure to cold and ergonomic stress from manual, repetitive tasks that require force. A PubMed, Medline and Science Direct online database search, using specific keywords was conducted and the results confirmed that physical and ergonomic hazards impact on abattoir processing workers health, with harm not only to workers' health but also as an economic burden due to the loss of their livelihoods and the need for treatment and compensation in the industry. This review endeavours to highlight the contribution poultry processing plays in the development of physical agents and ergonomic stress related occupational diseases in poultry abattoir processing workers. The impact includes noise-induced hearing loss, increased blood pressure, menstrual and work related upper limb disorders. These are summarised as a quick reference guide for poultry abattoir owners, abattoir workers, poultry associations, occupational hygienists and medical practitioners to assist in the safer management of occupational health in poultry abattoirs.

Environmental justice: implications for occupational health nurses.

2006-11-01

Through the use of innovative tools, such as clinical mnemonics, exercises in risk and asset mapping, and strategic program development, occupational health nurses can incorporate dimensions of environmental justice (EJ) into the workplace. Occupational health nurses who also take on educational roles can use case studies and network with labor and EJ groups to provide clinical experiences for occupational and environmental health nursing students, thereby integrating EJ into occupational and environmental health nursing practice. Occupational health nurses are well positioned to serve as technical experts within community-based participatory research projects. Occupational health nurses must share their knowledge and experience as members of coalitions that represent workers in their fight for worker health and safety.

This cross-sectional study explored associations of irregular menstruation with occupational characteristics, using secondary analyses of data from 4,731 women aged 19-54 years, collected from a nationally representative sample, the Korea National Health and Nutrition Examination Survey-V during 2010-2012. The associations between irregular menstruation and occupation were explored using multiple logistic regression. Compared to non-manual workers, service/sales workers had a greater odds of irregular menstruation (adjusted odds ratio [aOR]: 1.44; 95percent confidence interval [CI]: 1.04-1.99) as did manual workers and unemployed women (aOR: 1.56; 95percent CI: 1.10-2.22, aOR: 1.46; 95percent CI: 1.14-1.89, respectively). Compared to regular workers, temporary workers and unemployed women had aORs of 1.52 (95percent CI: 1.08-2.13) and 1.33 (95percent CI: 1.05-1.69), respectively. Also, when compared to full-time workers, part-time workers and unemployed women had greater odds of irregular menstruation (aOR: 1.41; 95percent CI: 1.00-2.00 and aOR: 1.29; 95percent CI: 1.03-1.63, respectively). Furthermore, compared to daytime workers, shift workers and unemployed women had greater odds irregular menstruation (aOR: 1.39; 95percent CI: 1.03-1.88 and aOR: 1.28; 95percent CI: 1.04-1.59, respectively). Women with these occupational characteristics should be screened for early diagnosis and intervention for irregular menstruation.

To describe data from the National Health Interview Survey (NHIS), both the annual core survey and periodic occupational health supplements (OHSs), available for examining national trends in worker health. The NHIS is an annual in-person household survey with a cross-sectional multistage clustered sample design to produce nationally representative health data. The 2010 NHIS included an OHS. Prevalence rates of various health conditions and health behaviors among workers based on multiple years of NHIS core data are available. In addition, the 2010 NHIS-OHS data provide prevalence rates of selected health conditions, work organization factors, and occupational exposures among US workers by industry and occupation. The publicly available NHIS data can be used to identify areas of concern for various industries and for benchmarking data from specific worker groups against national averages.

2015-01-01

Objective To identify the factors associated with fatal occupational injuries in Mexico in 2012 among workers affiliated with the Mexican Social Security Institute. Methods Analysis of secondary data using information from the National Occupational Risk Information System, with the consequence of the occupational injury (fatal versus non-fatal) as the response variable. The analysis included 406,222 non-fatal and 1,140 fatal injuries from 2012. The factors associated with the lethality of the injury were identified using a logistic regression model with the Firth approach. Results Being male (OR=5.86; CI95%: 4.22-8.14), age (OR=1.04; CI95%: 1.03-1.06), employed in the position for 1 to 10 years (versus less than 1 year) (OR=1.37; CI95%: 1.15-1.63), working as a facilities or machine operator or assembler (OR: 3.28; CI95%: 2.12- 5.07) and being a worker without qualifications (OR=1.96; CI95%: 1.18-3.24) (versus an office worker) were associated with fatality in the event of an injury. Additionally, companies classified as maximum risk (OR=1.90; CI 95%: 1.38-2.62), workplace conditions (OR=7.15; CI95%: 3.63-14.10) and factors related to the work environment (OR=9.18; CI95%:4.36-19.33) were identified as risk factors for fatality in the event of an occupational injury. Conclusions Fatality in the event of an occupational injury is associated with factors related to sociodemographics (age, sex and occupation), the work environment and workplace conditions. Worker protection policies should be created for groups with a higher risk of fatal occupational injuries in Mexico. PMID:25790063

Chemical exposure in occupational settings and related health risks: a neglected area of research in Pakistan.

Kamal, Atif; Malik, Riffat Naseem; Fatima, Noreen; Rashid, Audil

2012-07-01

In Pakistan a huge number of workers is routinely exposed to various types of chemical contaminants but there is a dearth of information as to the impact of these agents, due to a lack of a routine surveillance system and proper reporting. Prolonged and sometimes acute occupational exposures to varied organic chemicals may result in numerous health related problems. Studies from all over the world have shown adverse health outcomes of chemicals that are commonly used in various occupations. Such chemical exposures are not just confined to the workplace, but the residents surrounding industrial sites also face significant health risks due to indirect chemical exposure. Occupational exposure is a multidimensional risk factor that varies from one occupation to another, and is associated with health decline in workers. Common determinants of workplace hazards include improper, or lack of use of self-protective equipment, active and passive exposure to cigarette smoke as well as the socio-demographic and economic background of workers. There may be more than one cause of occupational stress and psychophysical disturbance among workers such as workload, lower salaries, and lack of social and medical facilities; indeed, their general health is poor. Therefore, in Pakistan, it is particularly important to focus on these issues and set rules and regulations to create occupational hazard awareness among workers, which will promote health safety at work places. If priorities are given to the correct use of self-protective equipment, adopting proper hygiene at the workplace and to avoid smoking, occupational exposures and consequent health risks may be minimized significantly.

2012-01-01

Objectives. We examined the association between US workers’ access to paid sick leave and the incidence of nonfatal occupational injuries from the employer’s perspective. We also examined this association in different industries and occupations. Methods. We developed a theoretical framework to examine the business value of offering paid sick leave. Data from the National Health Interview Survey were used to test the hypothesis that offering paid sick leave is associated with a reduced incidence of occupational injuries. We used data on approximately 38 000 working adults to estimate a multivariate model. Results. With all other variables held constant, workers with access to paid sick leave were 28% (95% confidence interval = 0.52, 0.99) less likely than workers without access to paid sick leave to be injured. The association between the availability of paid sick leave and the incidence of occupational injuries varied across sectors and occupations, with the greatest differences occurring in high-risk sectors and occupations. Conclusions. Our findings suggest that, similar to other investments in worker safety and health, introducing or expanding paid sick leave programs might help businesses reduce the incidence of nonfatal occupational injuries, particularly in high-risk sectors and occupations.

The Study Model for Future Occupational Health (funded by a research grant from the Ministry of Health, Welfare and Labor) is a joint research project involving various organizations and agencies undertaken from 2002 to 2004. Society has undergone a dramatic transformation due to technological developments and internationalization. At the same time a low birth rate and an aging population have resulted in an increase in both the percentage of workers experiencing strong anxiety and stress in relation to their jobs and the working environment and the number of suicides. As a natural consequence, occupational health services are now expected to provide EAP, consulting and other functions that were formerly considered outside the realm of occupational health. In consideration of this background, the present study propose the following issues to provide a model for future occupational health services that meet the conditions presently confronted by each worker. 1. How to provide occupational health services and occupational physicians' services: 1) a basic time of 20 minutes of occupational health services per year should be allotted to each worker and to all workers; 2) the obligatory regulations should be revised to expand the obligation from businesses each with 50 or more employees under the present laws to businesses each with 30 or more employees. 2. Providers of occupational health services and occupational physicians' services: (1) reinforcement of outside occupational health agencies; (2) fostering occupational health consultant firms; (3) development of an institute of occupational safety and health; (4) support of activities by authorized occupational physicians in the field; (5) expanding of joint selection of occupational physicians including subsidy increase and the extension of a period of subsidy to five hears; (6) licensing of new entry into occupational health undertaking. 3. Introduction of new report system: (1) establishment of the obligation to submit reports on risk evaluation and improvement measures; (2) establishment of the obligation to prepare a report on results of medical examinations in all sizes of businesses. 4. Introduction of a merit system into businesses in establishment of a new system: the application of the special merit system of the workers' compensation insurance shall be revised to add occupational health activities, cover business with 20 or more to 100 or less employees and expand the period of application for three years under the present laws to five years. 5. Ensuring of international coordination: harmonization of standards of individual countries for occupational health and safety; thorough (1) ensuring of international agreement on high-level specialist qualifications; (2) mutual recognition of qualifications of occupational physician, nurse, occupational hygienist, ergonomist, and counselor; (3) preparation of guidelines for occupations relating to occupational health businesses.

A trial of a job-specific workers' health surveillance program for construction workers: study protocol

PubMed Central

2011-01-01

Background Dutch construction workers are offered periodic health examinations. This care can be improved by tailoring this workers health surveillance (WHS) to the demands of the job and adjust the preventive actions to the specific health risks of a worker in a particular job. To improve the quality of the WHS for construction workers and stimulate relevant job-specific preventive actions by the occupational physician, we have developed a job-specific WHS. The job-specific WHS consists of modules assessing both physical and psychological requirements. The selected measurement instruments chosen, are based on their appropriateness to measure the workers' capacity and health requirements. They include a questionnaire and biometrical tests, and physical performance tests that measure physical functional capabilities. Furthermore, our job-specific WHS provides occupational physicians with a protocol to increase the worker-behavioural effectiveness of their counselling and to stimulate job-specific preventive actions. The objective of this paper is to describe and clarify our study to evaluate the behavioural effects of this job-specific WHS on workers and occupational physicians. Methods/Design The ongoing study of bricklayers and supervisors is a nonrandomised trial to compare the outcome of an intervention (job-specific WHS) group (n = 206) with that of a control (WHS) group (n = 206). The study includes a three-month follow-up. The primary outcome measure is the proportion of participants who have undertaken one or more of the preventive actions advised by their occupational physician in the three months after attending the WHS. A process evaluation will be carried out to determine context, reach, dose delivered, dose received, fidelity, and satisfaction. The present study is in accordance with the TREND Statement. Discussion This study will allow an evaluation of the behaviour of both the workers and occupational physician regarding the preventive actions undertaken by them within the scope of a job-specific WHS.

Asfaw, Abay; Souza, Kerry

2012-09-01

We examined if injured workers were more likely than noninjured workers to be treated for depression after an occupational injury and estimated the cost paid by group medical insurance. Nearly 367,900 injured and noninjured workers were drawn from the 2005 Thomson Reuters MarketScan data. Descriptive, logistic, and two-part model regression analyses were used. The odds of injured workers being treated for depression within the study period were 45% higher than those of noninjured workers (95% confidence interval, 1.17-1.78). The unconditional average cost of outpatient depression treatment was 63% higher for injured workers than for noninjured workers. Injured workers were more likely than noninjured workers to suffer from depression during the study period. Consequently, additional costs are incurred for treating injured workers' depression; these costs were not covered by the workers' compensation system.

To analyse the relationship between coping strategy and occupational stress in rail freight dispatchers. 115 rail freight dispatchers were investigated by using group sampling method, investigation contents included coping strategies, occupational stressors, strains and personalities. The proportion of using coping strategy in rail freight dispatchers is lower. The scores of job future ambiguity, type A behavior and work locus of control in workers with insufficient coping strategy were higher than those in workers with sufficient strategy (P < 0.05 or P < 0.01), but the score of organization commitment score in workers with insufficient coping strategy was lower than those in workers with sufficient strategy (P < 0.05), the differences of scores of some occupational stressor, strain and personality variables between workers with insufficient and those with sufficient in social support, job-family balance, job involvement coping factors of coping strategy were remarkable significant (P < 0.05 or P < 0.01), the differences of scores of occupational stressor, strain and personality variables between workers with insufficient and those with sufficient in ask, logic and time management factors of coping strategy weren't significant (P > 0.05). Logistic regression analysis showed that risk of being job dissatisfaction and daily life stress in workers with insufficient social support coping was three or four times than those with sufficient coping (OR = 3.06 or 4.38, respectively), risk of being daily life stress in workers with insufficient job involvement coping was three times than those with sufficient coping (OR = 3.26). The proportion of using coping strategy in rail freight dispatchers is lower. Coping strategy has influence on the individual's perception of occuaptional stressors, strains and personalities.

Recognizing occupational effects of diacetyl: What can we learn from this history?

Kreiss, Kathleen

2017-01-01

For half of the 30-odd years that diacetyl-exposed workers have developed disabling lung disease, obliterative bronchiolitis was unrecognized as an occupational risk. Delays in its recognition as an occupational lung disease are attributable to the absence of a work-related temporal pattern of symptoms; failure to recognize clusters of cases; complexity of exposure environments; and absence of epidemiologic characterization of workforces giving rise to case clusters. Few physicians are familiar with this rare disease, and motivation to investigate the unknown requires familiarity with what is known and what is anomalous. In pursuit of the previously undescribed risk, investigators benefited greatly from multi-disciplinary collaboration, in this case including physicians, epidemiologists, environmental scientists, toxicologists, industry representatives, and worker advocates. In the 15 years since obliterative bronchiolitis was described in microwave popcorn workers, α-dicarbonyl-related lung disease has been found in flavoring manufacturing workers, other food production workers, diacetyl manufacturing workers, and coffee production workers, alongside case reports in other industries. Within the field of occupational health, impacts include new ventures in public health surveillance, attention to spirometry quality for serial measurements, identifying other indolent causes of obliterative bronchiolitis apart from accidental over-exposures, and broadening the spectrum of diagnostic abnormalities in the disease. Within toxicology, impacts include new attention to appropriate animal models of obliterative bronchiolitis, pertinence of computational fluid dynamic-physiologically based pharmacokinetic modeling, and contributions to mechanistic understanding of respiratory epithelial necrosis, airway fibrosis, and central nervous system effects. In these continuing efforts, collaboration between laboratory scientists, clinicians, occupational public health practitioners in government and industry, and employers remains critical for improving the health of workers inhaling volatile α-dicarbonyl compounds.

Studies on occupational skin diseases in workers of the automotive industry are few. To investigate the prevalence of occupational skin diseases in workers of the automotive industry. Between September and December 2011, a total of 405 workers from the automotive repair industry in Diyarbakır were interviewed. They were active workers in the repair industry who had been employed for at least six months. Business owners, sellers of spare parts and accounting officers were not included. The employees were examined at their workplaces and the working conditions were observed. Detailed dermatological examination was performed. The mean age of the 405 workers who participated in the study was 27.7 ± 10.3. The mean working time of employees was 13.3 ± 10.4 years. All of the employees were male. Dermatological diseases were not detected in 144 out of 405 workers (35.6%) and at least one condition was diagnosed in 261 (64.4%). The most frequent diagnosis was callus, hyperkeratosis, clavus (27.7%), followed by nail changes (16.8%) and superficial mycoses (12.1%). Contact dermatitis was seen at a rate of 5.9%. Traumatic lesions such as hyperkeratotic lesions and nail changes were found most frequently. Traumatic lesions were common among individuals who did not use gloves. Most nail changes were localized leuconychia, a finding not reported in the studies on automotive industry workers. In accordance with the literature, irritant contact dermatitis was observed in patients with a history of atopy and who had been working for a long time. Occupational skin diseases comprise an important field in dermatology, deserving much attention. Further studies on occupational dermatology are necessary.

Among agricultural workers, especially in the seasonal migratory ones, housing and hygiene related issues, occupational accidents, low levels of education, poverty and absence of social security problems emerge as significant public health problems. This study aims to compare migrant-seasonal workers (MSWs) and resident agricultural workers (RAWs) in terms of socio-demographic characteristics and occupational health and safety in Adana, one of Turkey's most important agricultural cities. This cross-sectional study was conducted on RAWs and MSWs, aged 15-65, operating in the province of Adana. The calculated sample sizes for both MSWs and RAWs were distributed using stratified simple random sampling to five districts of Adana. The mean age of the 798 participating agricultural workers was 34.6 ± 14.2. Of the RAWs, 78.8% and of the MSWs 57.0% were male; 5.8% of RAWs and 32.8% of MSWs were illiterate. The mean number of people in the households of the participating workers was 5.1 for RAWs and 6.6 for MSWs. Of the RAWs, 20.5% were not covered by any social security scheme while this percentage was 35.1% in MSWs. RAWs worked 9.9 h a day while MSWs worked 10.9 h a day. Of the agricultural workers, 12.9% had injuries caused by occupational accidents. Agricultural workers, who are a large part of Turkey's economically active population, do not have healthy and safe working conditions. New regulations in the fields of social security, record keeping, monitoring, supervision, education and occupational health have been implemented recently to solve these problems. Despite the recent improvements there are still some problematic issues in the auditing of the necessary practices.

China has become a major economic influence in Asia and globally. The country is in the position to further develop its workers' insurance and compensation system. This paper aims to introduce the existing workers' compensation policies, explain how these policies guide the operation of the occupational rehabilitation system for injured workers, and suggest ways to further develop an effective and sustainable system for the country. Major government policies and initiative documents and existing literature on occupational rehabilitation were critically reviewed. Shortfalls in our current system were identified and potential further development regimes were propose. Since 2004, China has implemented its national policy on providing timely and comprehensive rehabilitation and return-to-work interventions for workers who are injured at work. The three-tier medical and occupational rehabilitation system appears effective for enabling injured workers to access these services. Such a system is regarded as the most optimal for the country in spearheading the development of quality occupational rehabilitation services, and at the same time incorporating the existing expertise in acute medical care and rehabilitation within the public medical and health system. Problems encountered in the system can be classified under the culture, system and competence building aspects. The future workers' insurance and compensation system can probably put more emphasis on using bio-psychosocial and work disability prevention models in guiding its service development and delivery. Efforts need to be placed on building the competence of professionals in the system who provide services for injured workers. The empowerment of important stakeholders in the workers' insurance and compensation system and their inclusion in the planning of service delivery are crucial for developing a sustainable and effective system for China.

The treatment and prevention of the metabolic syndrome (MetS) is currently one of the major challenges in medicine. The impact of working conditions on metabolic risk has not been adequately studied. Our objective was to compare the prevalence of MetS and metabolic risk in two extremely different occupational groups: firefighters and office workers. A total of 143 male subjects (97 firefighters and 46 office workers) from Germany participated in the study. Anthropometric characteristics, metabolic risk parameters as well as laboratory parameters were collected. MetS was diagnosed according to criteria of the International Diabetes Federation. Sedentary occupation showed a significant tendency towards obesity. Abdominal waist circumference was significantly greater in office workers than in firefighters [5.08 CI (1.44-8.71), p = 0.007]. Concerning metabolic risk factors, abnormal HDL, triglycerides, BMI, blood pressure and waist circumference values were more frequently found in office workers than in firefighters. The MetS was detected in almost 33 % of office workers as compared with only 14 % in firefighters (p = 0.015). Regarding MetS in an international comparison, the prevalence of MetS in German office workers was high and in firefighters it was extremely low. Sedentary occupation as an office worker is associated with a high risk of MetS. Both groups need to be made aware of the metabolic risks, and health promoting concepts such as corporate sports activities or education in healthy nutrition need to be implemented to counteract the development of the MetS and cardiovascular risk factors.

Occupational stress and unhealthy lifestyles are common characteristics of urban workers. The association between health behaviors and job stress of urban Brazilian civil servants was studied. A cross-sectional study included 893 workers. Health markers, the dependent variables, were: Fruit/vegetable (FV) and alcohol (A) intake, physical activity (PA), including at work (PAW), smoking (S), BMI ≥ 25 Kg/m(2). Occupational stress, assessed by Job Stress Scale-Brazilian version, classified employees into: High-strain, Low-strain, Active, and Passive. Prevalence rates and multivariate Poisson models were adopted. On average, employees (mean age = 40.2 years; 69.1% female) reported healthy lifestyle factors: FV (56%); PA (59.7%); S (13.3%); however, 49.4% were overweight. Compared to low-strain, high-strain workers reported higher PAW; passive workers lesser PA and higher PAW. After adjusting for socio-demographics and work characteristics, the occupational stress dimensions were no longer associated to health behaviors. Our results do not support the hypothesis of an effect for occupational stress on urban employees' health behaviors. Copyright © 2012 Wiley Periodicals, Inc.

To explore the nature and severity of occupational injuries among construction workers and its risk factors in Hong Kong. One hundred and twenty-two injured construction workers in a public hospital and an equal number of workmate controls were studied. Contents included socio -demographic characteristics, the availability and use of safety equipment, smoking and alcohol consumption, etc. Abbreviated injury scale (AIS) and injury severity score (ISS) were employed for describing the nature, pattern and severity of injuries. Single injuries were seen in 80% of cases. Of 149 injuries classified by body region, 49% were external, 26% involved either the upper or lower extremities, and 11% were spinal injuries. Working at height was associated with the injury severity score. Safety hazards were identified in the work environment in 68% of the cases. Significant odds ratios for accidents were obtained for 'no formal education', 'non safety training' and 'current smokers'. The results implicated that construction was a hazardous occupation in Hong Kong. Improving the work environment and promoting safety education among construction workers would be helpful for minimizing or eliminating occupational injuries in construction occupation in Hong Kong.

Sino-nasal cancer (SNC) are rare tumours with an elevated occupational etiological fraction, due both to well-established risk factors (wood and leather) and to more rare carcinogens. We evaluated the assessment for workers' compensation performed by the Italian Authority (INAL) in a case-series of occupational SNC (N = 45). We observed an elevated proportion of cases that were recognised as occupational, overall (36 on 39) and for any histotype. INAIL tended to recognize as professional not only patients with exposure to wood and leather but also cases with a documented exposure to formaldehyde, metal, polycyclic hydrocarbons. Significant differences across Italian macro-regions appeared, when the amount of worker compensation was investigated.

ABSTRACT Objective: To identify respiratory symptoms and evaluate lung function in mine workers. Methods: This was a cross-sectional observational study involving production sector workers of a pyrochlore mining company. The subjects completed the British Medical Research Council questionnaire, which is designed to evaluate respiratory symptoms, occupational exposure factors, and smoking status. In addition, they underwent pulmonary function tests with a portable spirometer. Results: The study involved 147 workers (all male). The mean age was 41.37 ± 8.71 years, and the mean duration of occupational exposure was 12.26 ± 7.09 years. We found that 33 (22.44%) of the workers had respiratory symptoms and that 26 (17.69%) showed abnormalities in the spirometry results. However, we found that the spirometry results did not correlate significantly with the presence of respiratory symptoms or with the duration of occupational exposure. Conclusions: The frequencies of respiratory symptoms and spirometric changes were low when compared with those reported in other studies involving occupational exposure to dust. No significant associations were observed between respiratory symptoms and spirometry results. PMID:27832236

A cross sectional survey was conducted among automobile mechanics and technicians in Ibadan to determine the socio-demographic characteristics and environmental hazards of these workers. Three hundred workers were interviewed. All respondents were males aged between 13 and 72 years of age. Educational attainment was poor, with only 20% of respondents having completed secondary education. Sanitation facilities were inadequate. Forty percent of workshops provided facilities for refuse disposal. Of the 33 workshops visited, only 1 provided toilet facilities. Most workers used facilities in neighbouring residential premises. Only three workshops (9%) had designated eating areas. Occupational exposure to petrol was common to all trades. Other occupational exposures were to petrochemicals such as engine oil and brake oil. Protective clothing was not used by the majority of workers. Only 25 (8%) respondents were wearing overalls at the time of our visit. This findings illustrate the typical work conditions of workers in small scale industries. There is a need for health education programmes about occupational and non-occupational diseases. This and other health promotion activities can be organized through the unions.

Mechanics are exposed to varied work stressors such as hot noisy environments, strenuous postures, improperly designed tools and machinery and poor psycho-social environments which may exert an influence on their health and safety. The study aimed to examine the occupational injury patterns and identify work stressors associated with injury amongst automobile mechanics. A descriptive ergonomic checklist and questionnaire on general health and psycho-social issues were administered to male workers (N=153). The relative risk factors and correlation statistics were used to identify the work stressors associated with occupational injury. 63% of the workers reported injuries. Cuts were the chief injuries being reported. Poor work environment, machinery and tool characteristics, suffering from poor health and psycho-social stressors were associated with injury occurrence amongst automobile repair workers.

Injuries to adolescents from occupational activities has been recognized as a significant public health concern. The objective of this study was to quantify adolescent injury rates, analyze risk factors, and measure the severity of injuries sustained using Oregon workers' compensation data. From 1990-1997, a total of 8060 workers' compensation claims, submitted by claimants 16-19 years old, were accepted by Oregon and used in these analyses. Data from the Bureau of Labor Statistics were used to derive injury rates. An overall estimated claim rate of 134.2 (95% confidence interval [CI] 124.9-143.6) per 10,000 adolescent workers was found, with males having over twice the rate of females. The total average annual claim cost was $3,168,457, representing $3145 per claim. The average total temporary disability period per claim was 22.3 days. Precision production workers had the highest claim rate of 296.2 (95% CI 178.9-413.4) and highest associated costs ($8266) for all occupations, whereas those in the farming/fishing/forestry occupation had the longest average periods of indemnification with 31.6 days. Day shift workers had the highest claim rates and most severe injuries relative to other shifts. The injury rates found among adolescent workers demonstrates that continued safety interventions and increased training are needed. Because of high claim rate and injury severity, particular attention should be focused on adolescents in food service, manufacturing, and agricultural occupations. Understanding the differences of adolescent circadian rhythm patterns in establishing work schedules and supervisory practices could also prove valuable for decreasing injury risk.

The operational role of the occupational health physician in the assessment and management of health risks related to night work. Night work, in the last 30-40 years, has been extended to almost all areas of employment. The potential effects on workers' health--related to the disruption of circadian rhythms--are now well defined and studied in the Literature. All issues about the protection of safety and health for night workers are governed by the Italian Legislative Decree no. 66/2003 and subsequent amendments. The management of night work hasn't been included into the main Law on Occupational Safety and Health (Italian Legislative Decree no. 81/2008 and subsequent amendments) and a coordination between the two disciplines is desirable. The occupational health physician, as a global consultant for the protection of all health issues into a company, has to evaluate the potential effects of night work on health, both individually and as a group of workers. In this way, the physician may use either traditional tools (history, physical examination, blood tests) or innovative tools (questionnaires, health promotion programs, interventions on shift schedules). In the management of night work is useful to employ schedules that respect both psychophysical integrity and social welfare of workers and the needs of the production. The occupational health physician plays a significant role in information and training of workers, both individually and as a group of workers, and in the organization of health promotion programs (whit a voluntary participation by the workers).

To investigate whether self-reported exposure to negative acts in the workplace (bullying and threats of violence) predicted turnover in three occupational groups (human service and sales workers, office workers and manual workers). Survey data on 2766 respondents were combined with data from a national labour force register to assess turnover. Mixed effects logistic regression analysis was used to examine the association between self-reported exposure to negative acts at baseline and risk of turnover after a 1-year follow-up. We found no significant associations between exposure to negative acts (bullying and threats of violence) and risk of turnover. When participants were stratified by occupational group and analyses were adjusted for age, gender, tenure and psychosocial working conditions, we found that exposure to bullying predicted risk of turnover in office workers (OR 2.03, 95 % CI 1.05-3.90), but neither in human service and sales workers, nor in manual workers. The association in office workers lost statistical significance when additionally adjusted for depressive symptoms (OR 1.77, 95 % CI 0.90-3.49). However, in a sensitivity analysis in which we used a 2-year (instead of a 1-year) follow-up period the association between bullying and turnover remained statistically significant in office workers even after adjusting for depressive symptoms (OR 2.10, 95 % CI 1.17-3.76). We found no statistically significant associations between threats of violence and risk of turnover in the stratified analyses. Exposure to bullying predicted risk of turnover among office workers but not among human service and sales workers and among manual workers. Threats of violence were not associated with turnover in any occupational group.

Occupational contact dermatitis is one of the most common occupational diseases in Europe. In order to develop effective preventive measures, detailed and up-to-date data on the incidence, main causes and professions at risk of occupational contact dermatitis are needed. To describe the pattern of patch test reactivity to allergens in the European baseline series of patients with occupational contact dermatitis in different occupations. We analysed data collected by the European Surveillance System on Contact Allergy (ESSCA) network from 2002 to 2010, from 11 European countries. Allergens in the European baseline series associated with an at least doubled risk of occupational contact dermatitis include: thiuram rubber chemical accelerators, epoxy resin, and the antimicrobials methylchloroisothiazolinone/methylisothiazolinone, methyldibromo glutaronitrile, and formaldehyde. The highest risk of occupational contact dermatitis was found in occupations classified as 'other personal services workers', which includes hairdressers, nursing and other healthcare professionals, precision workers in metal and related materials, and blacksmiths, tool-makers and related trades workers. In the planning and implementation of measures aimed at preventing occupational contact dermatitis, the focus should be on the identified high-risk occupational groups and the most common occupational allergies. © 2015 John Wiley & Sons A/S.

Sassler, Sharon; Levitte, Yael; Michelmore, Katherine M.

2014-01-01

We follow female college graduates in the National Longitudinal Survey of Youth 1979 and compare the trajectories of women in science, technology, engineering, and mathematics (STEM)-related occupations to other professional occupations. Results show that women in STEM occupations are significantly more likely to leave their occupational field than professional women, especially early in their career, while few women in either group leave jobs to exit the labor force. Family factors cannot account for the differential loss of STEM workers compared to other professional workers. Few differences in job characteristics emerge either, so these cannot account for the disproportionate loss of STEM workers. What does emerge is that investments and job rewards that generally stimulate field commitment, such as advanced training and high job satisfaction, fail to build commitment among women in STEM.

Dobson, Jessica A; Riddiford-Harland, Diane L; Bell, Alison F; Steele, Julie R

2017-05-01

Safety boots are compulsory in many occupations to protect the feet of workers from undesirable external stimuli, particularly in harsh work environments. The unique environmental conditions and varying tasks performed in different occupations necessitate a variety of boot designs to match each worker's occupational safety and functional requirements. Unfortunately, safety boots are often designed more for occupational safety at the expense of functionality and comfort. In fact, there is a paucity of published research investigating the influence that specific variations in work boot design have on fundamental tasks common to many occupations, such as walking. This literature review aimed to collate and examine what is currently known about the influence of boot design on walking in order to identify gaps in the literature and develop evidence-based recommendations upon which to design future research studies investigating work boot design.

Background Occupational status, a core component of socioeconomic status, plays a critical role in the well-being of U.S. workers. Identifying work-related disparities can help target prevention efforts. Methods Bureau of Labor Statistics workplace data were used to characterize high-risk occupations and examine relationships between demographic and work-related variables and fatality. Results Employment in high-injury/illness occupations was independently associated with being male, Black, ≤high school degree, foreign-birth, and low-wages. Adjusted fatal occupational injury rate ratios for 2005–2009 were elevated for males, older workers, and several industries and occupations. Agriculture/forestry/fishing and mining industries and transportation and materials moving occupations had the highest rate ratios. Homicide rate ratios were elevated for Black, American Indian/Alaska Native/Asian/Pacific Islanders, and foreign-born workers. Conclusions These findings highlight the importance of understanding patterns of disparities of workplace injuries, illnesses and fatalities. Results can improve intervention efforts by developing programs that better meet the needs of the increasingly diverse U.S. workforce. PMID:24436156

Objectives Lack of physical activity (PA) has been hypothesised as an underlying mechanism in the adverse health effects of shift work. Therefore, our aim was to compare non-occupational PA levels between shift workers and non-shift workers. Furthermore, exposure–response relationships for frequency of night shifts and years of shift work regarding non-occupational PA levels were studied. Methods Data of 5980 non-shift workers and 532 shift workers from the European Prospective Investigation into Cancer and Nutrition-Netherlands (EPIC-NL) were used in these cross-sectional analyses. Time spent (hours/week) in different PA types (walking/cycling/exercise/chores) and intensities (moderate/vigorous) were calculated based on self-reported PA. Furthermore, sports were operationalised as: playing sports (no/yes), individual versus non-individual sports, and non-vigorous-intensity versus vigorous-intensity sports. PA levels were compared between shift workers and non-shift workers using Generalized Estimating Equations and logistic regression. Results Shift workers reported spending more time walking than non-shift workers (B=2.3 (95% CI 1.2 to 3.4)), but shift work was not associated with other PA types and any of the sports activities. Shift workers who worked 1–4 night shifts/month (B=2.4 (95% CI 0.6 to 4.3)) and ≥5 night shifts/month (B=3.7 (95% CI 1.8 to 5.6)) spent more time walking than non-shift workers. No exposure–response relationships were found between years of shift work and PA levels. Conclusions Shift workers spent more time walking than non-shift workers, but we observed no differences in other non-occupational PA levels. To better understand if and how PA plays a role in the negative health consequences of shift work, our findings need to be confirmed in future studies. PMID:27872151

Maintaining work capacity in the aged worker via progressive resistance training: the implications for occupational therapy practitioners.

PubMed

Branch, N G

1998-01-01

Society has an interest in maintaining the work capacity of its aging workers. Fewer and fewer younger workers are entering the workforce to replace older citizens no longer able to perform the worker role. There is a demonstrated relationship between increased strength and work capacity, yet the occupational therapy literature emphasizes generalized exercise programming. This type of programming is ineffective at building strength in the elderly worker. High intensity progressive resistance exercise (PRE) can increase strength in the very old worker, yet therapists are hesitant to employ PRE, perhaps due to a potential bias against the use of high intensity PRE with this cohort. Use of PRE may present some difficulties in the clinical situation where continual supervision and resistance training equipment is not available. The adaptive use of functional activities as a resistance training strategy to build strength may be able to overcome the difficulties attendant with the use of PRE while preserving its benefits. Several other implications for occupational therapy practitioners are discussed.

2015-09-01

Although job-related diseases result in more deaths per year than job-related injuries, most research concerning ethnic minority workers has concerned accidents and injuries rather than disease-causing exposures such as carcinogens. We conducted a telephone-based cross-sectional survey to estimate the prevalence of occupational exposure to carcinogens among a sample of ethnic minority workers in Australia, and compared their exposure prevalence to that of a sample of the general Australian-born working population ('Australian workers'). One-third of the ethnic minority workers were exposed to at least one carcinogen at work. The likelihood of exposure to carcinogens was not significantly different from that of Australian workers, although the likelihood of exposure to individual carcinogens varied by ethnicity. Knowing the prevalence of exposure to carcinogens in the workplace in different ethnic groups will allow better targeted and informed occupational health and safety measures to be implemented where necessary. © 2015 Wiley Periodicals, Inc.

Studies have suggested that risk of leukemia may be associated with occupational or industrial exposures and risk may vary by the histological type of the disease. A population-based case-control study was conducted in Iowa and Minnesota to evaluate the association between various occupations, industries, and occupational exposures and leukemia risk. A total of 513 cases and 1,087 controls was included in the study. A lifetime occupational history and other risk factor information were collected through in-person interviews, and a job-exposure matrix was used to assess possible risks associated with specific exposures. A significantly increased risk of leukemia was observed among agricultural service industries and among nursing and healthcare workers. Janitors, cleaners, and light truck drivers also experienced increased risk. Those employed in plumbing, heating and air conditioning industries, and sales of nondurable goods (such as paints and varnishes) had an increased risk. Printers, painters, and workers in the food and metal industries had a nonsignificantly increased risk of leukemia. Analyses by specific exposures and histology of leukemia showed that risk of leukemia associated with occupational or industrial exposures may vary by histological type of the disease. An increased risk of leukemia among workers employed in agricultural industries, nursing and healthcare workers, and in a few occupations with possible exposure to solvents is consistent with earlier studies. Associations of risk with occupations not observed previously deserve further assessment. Published 2001 Wiley-Liss, Inc.

Objectives To estimate the numbers of workers exposed to known and suspected occupational carcinogens in Canada, building on the methods of CARcinogen EXposure (CAREX) projects in the European Union (EU). Methods CAREX Canada consists of estimates of the prevalence and level of exposure to occupational carcinogens. CAREX Canada includes occupational agents evaluated by the International Agency for Research on Cancer as known, probable or possible human carcinogens that were present and feasible to assess in Canadian workplaces. A Canadian Workplace Exposure Database was established to identify the potential for exposure in particular industries and occupations, and to create exposure level estimates among priority agents, where possible. CAREX EU data were reviewed for relevance to the Canadian context and the proportion of workers likely to be exposed by industry and occupation in Canada was assigned using expert assessment and agreement by a minimum of two occupational hygienists. These proportions were used to generate prevalence estimates by linkage with the Census of Population for 2006, and these estimates are available by industry, occupation, sex and province. Results CAREX Canada estimated the number of workers exposed to 44 known, probable and suspected carcinogens. Estimates of levels of exposure were further developed for 18 priority agents. Common exposures included night shift work (1.9 million exposed), solar ultraviolet radiation exposure (1.5 million exposed) and diesel engine exhaust (781 000 exposed). Conclusions A substantial proportion of Canadian workers are exposed to known and suspected carcinogens at work. PMID:24969047

Kaewboonchoo, Orawan; Kongtip, Pornpimol; Woskie, Susan

2018-01-01

Over 16.7 million workers in Thailand (42 percent of the working population) are engaged in agriculture, disproportionately from the lower socioeconomic strata of Thai society. Most agricultural workers (over 93 percent) work in the informal sector without the protections of regulations or enforcement of labor or health and safety laws or enrollment in a social security system. Although Thailand’s use of herbicides, fungicides, and insecticides is growing, there is little regulation of the sale, use, or application of these potentially toxic chemicals. This paper summarizes the research to date on occupational health and safety for Thai agricultural workers, identifies gaps in pesticide regulations and the current systems for occupational health and safety and social support for Thai agricultural workers, and makes recommendations for future policy and research initiatives to fill the identified gaps.

The role of worker education in preventing occupational lung disease.

PubMed

Kaufman, J D; Rosenstock, L

1991-01-01

Training and education of workers in order to prevent occupational lung diseases represent a challenge to employers, unions, clinicians, and other interested groups. Programs attempting to meet this need range from simple programs in respiratory protection fundamentals and smoking cessation to programs that teach workers to understand and demand their right to a safe and healthful workplace. Support for educational programs has come from diverse sources, including government, labor, business, and independent organizations. In some cases nonprofit organizations have developed innovative programs, but it is important that the burden of preventing occupational lung disease through education not be carried by charitable organizations alone. The role of the clinician in this effort is to educate workers at every opportunity regarding lung hazards and to use early evidence of respiratory damage as a lever to increase the worker's understanding of his or her role in health protection.

Objective We examined the association between job demand and occupational injury among older workers. Methods Participants were workers aged 50+ enrolled in the Health and Retirement Study, 2010–2014. Participants reported physical ability within three domains: physical effort, stooping/kneeling/crouching, and lifting. To measure subjective job demand, participants rated their job's demands within domains. We generated objective job demand measures through the Occupational Information Network (O*NET). Using Poisson regression, we modeled the association between physical ability, job demand, and self-reported occupational injury. A second model explored interaction between job demand and physical ability. Results The injury rate was 22 /1,000 worker-years. Higher job demand was associated with increased injury risk. Within high job demands, lower physical ability was associated with increased injury risk. Conclusions Older workers whose physical abilities do not meet job demands face increased injury risk.

Gumodoka, B; Favot, I; Berege, Z A; Dolmans, W M

1997-01-01

During 1993, we collected data on knowledge of human immunodeficiency virus (HIV) transmission, availability of equipment, protective practices and the occurrence of prick and splash incidents in nine hospitals in the Mwanza Region in the north-west of the United Republic of Tanzania. Such incidents were common, with the average health worker being pricked five times and being splashed nine times per year. The annual occupational risk of HIV transmission was estimated at 0.27% for health workers. Among surgeons, the risk was 0.7% (i.e. more than twice as high) if no special protective measures were taken. Health workers' knowledge and personal protective practices must therefore be improved and the supply of protective equipment supported. Reduction of occupational risk of HIV infection among health workers should be an integral part of acquired immunodeficiency syndrome (AIDS) control strategies.

Machinery-related occupational fatalities in the United States, 1980 to 1989.

Pratt, S G; Kisner, S M; Helmkamp, J C

1996-01-01

The National Traumatic Occupational Fatalities surveillance system identified machinery-related incidents as the second leading cause of traumatic occupational fatalities in the United States between 1980 and 1989. These incidents resulted in 8,505 civilian worker deaths and an average annual fatality rate of .80 per 100,000 workers. Workers aged 65 years and older had 5.8 times the fatality rate of workers aged 16 to 64 years (4.06 vs. 70). The highest industry-specific rate was noted in agriculture, forestry, and fishing (7.47). Tractors and other agricultural machinery were associated with nearly 9 of every 10 fatal machinery-related incidents involving workers aged 65 or older. Although numerous studies of agricultural machinery-related fatalities are found in the literature, detailed analyses of machinery-related fatalities in the construction industry as well as analyses of work situations and risk factors associated with fatal injuries are needed.

The Occupational Health Internship Program (OHIP) was initiated in 2003 to recruit a new, diverse generation of occupational safety and health (OSH) professionals and to advance OSH within union and community-based initiatives. It retains the principles of the original OCAW/Montefiore internship program while adapting to the changed landscape of the 21st-century workplace. Case studies of OHIP projects illustrate how students have contributed to key OSH policies-to regulate silica exposure among construction workers, apply principles of green chemistry with Vietnamese nail salon workers, and integrate OSH into "green" jobs in the recycling industry. They have supported innovative campaigns with immigrant workers in contingent jobs-from taxi drivers to warehouse workers. The students, in turn, have been inspired to enter the OSH arena as professionals and worker advocates with the potential to contribute new energy to an OSH movement.

The purpose of this study was to compare the prevalence of workers with National Institute for Occupational Safety and Health significant threshold shifts (NSTS), Occupational Safety and Health Administration standard threshold shifts (OSTS), and with OSTS with age correction (OSTS-A), by industry using North American Industry Classification System codes. From 2001 to 2010, worker audiograms were examined. Prevalence and adjusted prevalence ratios for NSTS were estimated by industry. NSTS, OSTS, and OSTS-A prevalences were compared by industry. Twenty percent of workers had an NSTS, 14% had an OSTS, and 6% had an OSTS-A. For most industries, the OSTS and OSTS-A criteria identified 28% to 36% and 66% to 74% fewer workers than the NSTS criteria, respectively. Use of NSTS criteria allowing for earlier detection of shifts in hearing is recommended for improved prevention of occupational hearing loss.

China's drive to modernize its economy will produce new occupational health problems even as it resolves earlier ones. Well aware of this, Chinese occupational health experts are intensifying efforts to improve workers' health and establish a modern occupational health program. Occupational lung disease, occupational cancer, heavy metal poisoning, industrial chemical poisoning, and physical factor-induced diseases (noise and heat) have all been targeted for expanded research which will serve as a basis for standard setting. Hazard control efforts include engineering controls, particularly in new construction, limited use of personal protective equipment, and expansion of environmental and medical monitoring. Worker education and professional activities have been expanded. International exchanges have been initiated and will prove occupational health a promising area of scientific cooperation.

2012-12-01

In 2010, wind energy coverage in Spain increased by 16%, making the country the world's fourth largest producer in a fast-developing industry that is also a source of employment. Occupational skin diseases in this field have received little attention. The present study aims to describe the main characteristics of skin diseases affecting workers in the wind energy industry and the allergens involved. We performed a descriptive, observational study of workers from the wind energy industry with suspected contact dermatitis who were referred to the occupational dermatology clinic of the National School of Occupational Medicine (Escuela Nacional de Medicina del Trabajo) between 2009 and 2011. We took both a clinical history and an occupational history, and patients underwent a physical examination and patch testing with the materials used in their work. We studied 10 workers (8 men, 2 women), with a mean age of 33.7 years. The main finding was dermatitis, which affected the face, eyelids, forearms, and hands. Sensitization to epoxy resins was detected in 4 workers, 1 of whom was also sensitized to epoxy curing agents. One worker was sensitized to bisphenol F resin but had a negative result with epoxy resin from the standard series. In the 5 remaining cases, the final diagnosis was irritant contact dermatitis due to fiberglass. Occupational skin diseases are increasingly common in the wind energy industry. The main allergens are epoxy resins. Fiberglass tends to produce irritation. Copyright © 2012 Elsevier España, S.L. and AEDV. All rights reserved.

Occupational ladder fall injuries - United States, 2011.

Socias, Christina M; Chaumont Menéndez, Cammie K; Collins, James W; Simeonov, Peter

2014-04-25

Falls remain a leading cause of unintentional injury mortality nationwide [corrected].Among workers, approximately 20% of fall injuries involve ladders. Among construction workers, an estimated 81% of fall injuries treated in U.S. emergency departments (EDs) involve a ladder. To fully characterize fatal and nonfatal injuries associated with ladder falls among workers in the United States, CDC's National Institute for Occupational Safety and Health (NIOSH) analyzed data across multiple surveillance systems: 1) the Census of Fatal Occupational Injuries (CFOI), 2) the Survey of Occupational Injuries and Illnesses (SOII), and 3) the National Electronic Injury Surveillance System-occupational supplement (NEISS-Work). In 2011, work-related ladder fall injuries (LFIs) resulted in 113 fatalities (0.09 per 100,000 full-time equivalent [FTE] workers), an estimated 15,460 nonfatal injuries reported by employers that involved ≥1 days away from work (DAFW), and an estimated 34,000 nonfatal injuries treated in EDs. Rates for nonfatal, work-related, ED-treated LFIs were higher (2.6 per 10,000 FTE) than those for such injuries reported by employers (1.2 per 10,000 FTE). LFIs represent a substantial public health burden of preventable injuries for workers. Because falls are the leading cause of work-related injuries and deaths in construction, NIOSH, the Occupational Safety and Health Administration, and the Center for Construction Research and Training are promoting a national campaign to prevent workplace falls. NIOSH is also developing innovative technologies to complement safe ladder use.

Occupational asthma in the furniture industry: is it due to styrene?

2004-01-01

Styrene, a volatile monomer, has been reported as a cause of occupational asthma in a few case reports. The aim of this study was to investigate the risk for asthma in relation to exposure to styrene in a large number of workers. A total of 47 workers with a history of exposure to styrene were included in the study. To establish whether asthma was present, each patient underwent a clinical interview, pulmonary function testing and bronchial challenge with methacholine. Specific bronchial challenges with styrene and serial peak expiratory flow (PEF) measurement at home and at work were carried out in subjects with a diagnosis of asthma to evaluate the relationship between their asthma and exposure to styrene in the workplace. Among the 47 subjects, 5 workers had given a history of work-related symptoms, and 3 of them had a positive methacholine challenge test. Specific bronchial challenges with styrene and serial PEF measurement were subsequently carried out in these 3 subjects. Although provocation tests with styrene were negative in the 3 workers, 1 worker had PEF rate records compatible with occupational asthma. We established one patient with occupational asthma from a group of people who have excessive styrene exposure. This finding may be suggestive but is not conclusive about the causative role of styrene in occupational asthma. Since styrene is a frequently used substance in the furniture industry, it is worth performing further studies to investigate the relationship between styrene and occupational asthma.

Workers in various industries and occupations are at risk for work-related asthma* (1). Data from the 2006-2007 adult Behavioral Risk Factor Surveillance System (BRFSS) Asthma Call-back Survey (ACBS), an in-depth asthma survey conducted with respondents who report an asthma diagnosis, from 33 states indicated that up to 48% of adult current asthma might be related to work and could therefore potentially be prevented (2). Identification of the industries and occupations with increased prevalence of asthma might inform work-related asthma intervention and prevention efforts. To assess the industry-specific and occupation-specific proportions of adults with current asthma by state, CDC analyzed data from the 2013 BRFSS industry and occupation module, collected from 21 states for participants aged ≥18 years who, at the time of the survey interview, were employed or had been out of work for <12 months. Among these respondents, 7.7% had current asthma; based on the Asthma Call-back Survey results, this finding means as many as 2.7 million U.S. workers might have asthma caused by or exacerbated by workplace conditions. State-specific variations in the prevalence of current asthma by industry and occupation were observed. By state, current asthma prevalence was highest among workers in the information industry (18.0%) in Massachusetts and in health care support occupations (21.5%) in Michigan. Analysis of BRFSS industry and occupation and optional asthma modules can be used to identify industries and occupations to assess for asthma among workers, identify workplace exposures, and guide the design and evaluation of effective work-related asthma prevention and education programs (1).

The objective of this study was to clarify the status of occupational health and safety services for immigrant workers, the barriers to employing immigrant workers and the needs of the managers in workplaces to keep immigrant workers healthy and safe. This study was a cross-sectional survey. We sent self-administered questionnaires to 126 workplaces in the western part of Shizuoka Prefecture, Japan in August 2006. The questionnaire included the characteristics of the workplace, barriers to employing immigrant workers, current actions to keep immigrant workers healthy and safe, the implementation rate of health checkups and important issues to keep immigrant workers healthy and safe. Implementation rates of health and safety education, creating job instruction manuals written in their native languages, creating safety signs written in their native languages, and the use of translators were 62.5%, 50.0%, 41.1% and 37.5%, respectively. Implementation rates of general health checkups, special health checkups and follow up after health checkups were 80.8%, 73.6% and 67.3%, respectively. The most important issue which the managers considered kept immigrant workers healthy and safe was health checkups (69.6%). In conclusion, several occupational health and safety services were conducted for immigrant workers without a margin to compare with Japanese workers.

Relative to other occupational groups in Britain, construction workers have a high incidence of skin cancer attributable to sun exposure. The importance of sun safety measures to minimize the risk of skin cancer is recognized in the literature; however, little is known about the factors associated with their use by construction workers. Knowledge in this area could help inform interventions to encourage sun safety behaviour within the sector. To investigate socio-demographic and occupational characteristics associated with the use of sun safety measures among construction workers in Britain. Data collection was by means of a self-administered questionnaire, which was sent to 360 construction workers. Information collected included socio-demographic and occupational characteristics and the use of sun safety measures. Participants worked outdoors for an average of 6.6 h/day. Three specific sun safety measures were used by the majority of respondents. Logistic regression analyses showed that certain socio-demographic and occupational factors were associated with the use of sun safety measures. In particular, receipt of sun safety training was positively associated with the wearing of long sleeved, loose fitting tops and trousers (OR, 1.69; 95% CI, 1.02-2.80) and sunglasses (OR, 1.85; 95% CI, 1.10-3.13). The results highlight the importance of employer-led sun safety interventions in the British construction industry. Interventions that take account of demographic and occupational characteristics are likely to have a positive impact in terms of improving workers' use of sun safety measures.

Perspectives of the community-based dementia care workforce: "occupational communion" a key finding from the Work 4 Dementia Project.

Community care workers' experience of delivering support to people with dementia is less researched than that of residential workers. The purpose of the study is to explore community-based dementia care workers' perspectives about their roles and the contextual variables that impact upon their work experiences. A qualitative design was employed. Twenty-five community dementia care workers (average age 53 years, majority female and employed casually) participated in standardized semi-structured interviews about their job roles, training, employer agenda, organizational support, and intention to stay. A deductive approach to Interpretive Phenomenological Analysis was adopted to identify key themes. Three themes highlighted workers' experiences. Occupational communion described strong attachment to clients and a desire for greater connection with colleagues. Job demands described the challenges of work, which varied with intensity. Job resources ranged from positive (strong organizational commitment) to negative (poor pay and conditions). Occupational communion was identified as a concept that exists at the interface between social and organization psychology that was perceived to be essential for adaptive coping. Identifying themes informed a conceptual model for designing intervention components aimed at improving workers' skills, capabilities, and employer supportive functions. Occupational communion may be particularly relevant for women's caring careers and future research is needed to explore the relevance of this concept for men. To determine reliable change associated with interventions that target occupational communion, further investigation is required in relation to measurement approaches.

The purpose of this study was to investigate the cross-sectional association of employment contract, company size, and occupation with psychological distress using a nationally representative sample of the Japanese population. From June through July 2007, a total of 9,461 male and 7,717 female employees living in the community were randomly selected and surveyed using a self-administered questionnaire and interview including questions about occupational class variables, psychological distress (K6 scale), treatment for mental disorders, and other covariates. Among males, part-time workers had a significantly higher prevalence of psychological distress than permanent workers. Among females, temporary/contract workers had a significantly higher prevalence of psychological distress than permanent workers. Among males, those who worked at companies with 300-999 employees had a significantly higher prevalence of psychological distress than those who worked at the smallest companies (with 1-29 employees). Company size was not significantly associated with psychological distress among females. Additionally, occupation was not significantly associated with psychological distress among males or females. Similar patterns were observed when the analyses were conducted for those who had psychological distress and/or received treatment for mental disorders. Working as part-time workers, for males, and as temporary/contract workers, for females, may be associated with poor mental health in Japan. No clear gradient in mental health along company size or occupation was observed in Japan.

Mobility for care workers: job changes and wages for nurse aides.

Ribas, Vanesa; Dill, Janette S; Cohen, Philip N

2012-12-01

The long-term care industry in the United States faces serious recruitment and retention problems among nurse aides. At the same time, these low-wage workers may feel trapped in poorly-paid jobs from which they would do well to leave. Despite this tension, not enough is known about how workers fare when they leave (or stay in) such care work. Using longitudinal data from the Survey of Income and Program Participation for the years 1996-2003, we examine the relationship between different job and occupational mobility patterns and wage outcomes for nurse aides, focusing on which job transitions offer better opportunities to earn higher wages and on whether job transition patterns differ by race. Our results confirm high turnover among nurse aides, with 73 percent of the sample working in occupations other than nurse aide at some point during the survey time frame. About half of respondents that transition out of nurse aide work move into higher-paying occupations, although the percentage of transitions to higher paying occupations drops to 35 percent when nurse aides that become RNs are excluded. Among black workers especially, wage penalties for moving into other jobs in the low-wage labor market appear to be rather small, likely a factor in high turnover among nurse aides. The findings illustrate the importance of occupation-specific mobility trajectories and their outcomes for different groups of workers, and for understanding the constrained decisions these workers make.

' Work related musculoskeletal disorders (WRMSDs)' have been mostly reported in the manufacturing industry but recently the occurrence of industrial injuries has been constantly increasing in the service industry. This research is going to analyze the data about workers' compensation for WRMSDs in five different service sectors and identify characteristics of occupations with the highest approved occupations. According to the data released from the Korea Worker's Compensation & Welfare Service, the overview of 12,730 cases of workers' compensation for WRMSDs in five service sectors from 2004 to 2013 is going to be analyzed and the source data is going to be classified by the Korean Standard Classification of Occupations to select the top five occupations that have the highest number of approval. After selecting each five occupations from the service sector that have work related musculoskeletal disorders, the result showed that the occupation with the highest number of approval in the health and social care sector were the early childhood educators, cooks in the school canteens in education services sector, garbage collectors in the sanitation and similar services sector, deliverymen in wholesale and retail, consumer goods repair and building cleaners in general management businesses such as those in building maintenance. The major event observed in the top five occupations was the overexertion and reaction as a cause of WRMSDs. The day when the WRMSDs mostly occurred was on Monday and the most likely time was 10 am. The median days away from work and lost working days are 29-90 days and 0-50 days respectively. The difference in each occupation was observed in year of service, age, and gender. 83.21% of the approved cases of workers' compensation for WRMSDs occurred in the top 25 occupations in all of the five service sectors, which meant that the approval of workers' compensation is concentrated in specific occupations. This research is going to suggest preventive measures for work related musculoskeletal disorders in the service industry and to help prioritize the preventive measures. Not applicable.

The aim of this paper was to ascertain chronic obstructive pulmonary disease (COPD) prevalence among industrial workers in the Russian Federation and determine relative contribution of smoking and occupational factors to COPD. We recruited 1,375 workers aged 30 or over. Six hundred and twenty-four of them were occupationally exposed to vapours, gases, dust, and fumes (VGDF). Physical examination and baseline spirometry were performed for all the participants of the study. Those with airfl ow limitation of FEV1/FVC<0.70 were considered having COPD and those with presence of cough and sputum production for at least three months in each of two consecutive years were considered having chronic bronchitis (CB), with no overlapping between these 2 groups. Data on occupational history and VGDF levels in the working area were collected from all participants. In total, 105 cases of COPD and 170 cases of CB were diagnosed in the cohort of examined workers. Occupational exposure to VGDF was twice as often present among COPD patients than among both patients with CB and the control group of healthy workers (p<0.05). More than 40 % of COPD patients were occupationally exposed to VGDF above the value of 3.0 of the occupational exposure limit (OEL) and more than 20 % to 6.0 OEL and higher. Overall odds ratio for COPD development due to occupational VGDF exposure was 5.9 (95 % CI=3.6 to 9.8, p=0.0001). Both smoking and VGDF seem to be important for the development of COPD. Analysis of the combined effect of tobacco smoking and occupational noxious particles and gases on COPD development has shown the following order of risk factors based on the strength of their infl uence: VGDF levels, smoking index, age, and heating microclimate. There is a statistically signifi cant level of relationship and "dose-effect" dependence between occupational exposures to VGDF and the development of COPD. The effect of VGDF composition on the probability of COPD development was not found in the study. Results of this study were used to substantiate the inclusion of COPD into the National List of Occupational Diseases of the Russian Federation.

2015-01-01

Objectives We examined if injured workers were more likely than noninjured workers to be treated for depression after an occupational injury and estimated the cost paid by group medical insurance. Method Nearly 367,900 injured and noninjured workers were drawn from the 2005 Thomson Reuters MarketScan data. Descriptive, logistic, and two-part model regression analyses were used. Results The odds of injured workers being treated for depression within the study period were 45% higher than those of noninjured workers (95% confidence interval, 1.17–1.78). The unconditional average cost of outpatient depression treatment was 63% higher for injured workers than for noninjured workers. Conclusions Injured workers were more likely than noninjured workers to suffer from depression during the study period. Consequently, additional costs are incurred for treating injured workers' depression; these costs were not covered by the workers' compensation system. PMID:22929794

Although several studies have examined the link between specific working conditions and health behaviours, very few have comparatively assessed the health behaviours of different occupational groups. To compare protective and risky health behaviours among police officers, ambulance workers, hospital staff (doctors and nurses) and office workers, prompted by the need to identify key areas for interventions tailored to the needs of different occupational groups. A cross-sectional postal survey using the Health Behaviours Inventory, assessing health behaviours which are risky (alcohol intake, smoking, coffee consumption, fast food meals and painkiller consumption) and protective (physical activity, eating breakfast and hours of sleep). The sample consisted of 1451 employees. Ambulance workers smoked the most cigarettes per day (F (4, 1405) = 8.63, P < 0.01), while doctors consumed twice as many fast food meals as any other occupational group (F (4, 1415) = 78.45, P < 0.01) and had the highest daily caffeine consumption (F (4, 1440) = 11.17, P < 0.01). Ambulance workers and doctors reported the highest frequency of alcohol consumption per week (F (4, 1421) = 10.13, P < 0.01). In regard to protective health behaviours, office workers reported the highest number of breakfast meals per week (F (4, 1431) = 5.7, P < 0.01) and sleeping hours per night (F (4, 1438) = 170.34, P < 0.01), while police officers and ambulance workers exercised more frequently (F (4, 1420) = 5.764, P < 0.01). The results of the study highlight key priorities for health promotion for different occupational groups which need to be taken into consideration in policy making and developing workplace interventions. © The Author 2015.

Management System of Occupational Diseases in Korea: Statistics, Report and Monitoring System

PubMed Central

Choe, Seong Weon

2010-01-01

The management system of occupational diseases in Korea can be assessed from the perspective of a surveillance system. Workers' compensation insurance reports are used to produce official statistics on occupational diseases in Korea. National working conditions surveys are used to monitor the magnitude of work-related symptoms and signs in the labor force. A health examination program was introduced to detect occupational diseases through both selective and mass screening programs. The Working Environment Measurement Institution assesses workers' exposure to hazards in the workplace. Government regulates that the employer should do health examinations and working conditions measurement through contracted private agencies and following the Occupational Safety and Health Act. It is hoped that these institutions may be able to effectively detect and monitor occupational diseases and hazards in the workplace. In view of this, the occupational management system in Korea is well designed, except for the national survey system. In the future, national surveys for detection of hazards and ill-health outcomes in workers should be developed. The existing surveillance system for occupational disease can be improved by providing more refined information through statistical analysis of surveillance data. PMID:21258584

Diesel exhaust causing low-dose irritant asthma with latency?

2009-09-01

Diesel exhaust exposure may cause acute irritant-induced asthma and potentiate allergen-induced asthma. There are no previous reports of occupational asthma due to diesel exhaust. To describe occupational asthma with latency in workers exposed to diesel exhaust in bus garages. The Shield database of occupational asthma notifications in the West Midlands, UK, was searched between 1990 and 2006 for workers where diesel exhaust exposure was thought to be the cause of the occupational asthma. Those without other confounding exposures whose occupational asthma was validated by serial peak expiratory flow (PEF) analysis using Oasys software were included. Fifteen workers were identified with occupational asthma attributed to diesel exhaust. Three had validated new-onset asthma with latency. All worked in bus garages where diesel exhaust exposure was the only likely cause of their occupational asthma. Occupational asthma was confirmed by measures of non-specific reactivity and serial measurements of PEF with Oasys scores of 2.9, 3.73 and 4 (positive score > 2.5). The known non-specific irritant effects of diesel exhaust suggest that this is an example of low-dose irritant-induced asthma and that exposures to diesel exhaust in at least some bus garages are at a sufficient level to cause this.

This study examines the trends in rates of fatal occupational injuries in Taiwan by demographic group and occupation for 1994-2005. Data on deaths due to injuries at work from 1994 through 2005 were obtained from the Department of Health which is responsible for the death registration system in Taiwan. Employment data, which were used as the denominators of fatality rates in this study, were retrieved from the Directorate-General of Budget and Accounting Statistics 'Employment and Earnings' database. A Poisson regression model was used to examine the trends in rates of fatal occupational injuries in various occupations while controlling for demographic characteristics. Overall fatal occupational injury rates declined during the study period among all demographic groups and occupations. Adjusted annual changes in rates of fatal injuries ranged from a decrease of 13.6% a year in machine operators/related workers to a decrease of 35.9% in clerks. The annual decrement was faster for males than for females and for older workers compared to young workers. Despite declining rates, the number of fatal occupational injuries in Taiwan remains significant because of the growing work force. Future research should focus on the disparities in fatal injury trends.

2010-10-01

Occupational injuries to adolescents and young adults are a known public health problem. We sought to describe and estimate rates of occupational injuries to workers younger than 25 years of age in Oregon during an 8-year period. Oregon workers' compensation disabling claims data (n = 23,325) and one commercial insurance carrier's non-disabling claims data (n = 16,153) were analyzed. Total employment from the Local Employment Dynamics of the U.S. Census Bureau and the Oregon Labor Market Information System was used as a denominator for rates. Injuries were more frequent among 22-24 year olds and among males, though females accounted for a higher proportion of claims in the youngest age group. The most common injury type was a sprain or strain, but lacerations and burns were more frequently reported in the 14-18 year olds. When non-disabling claims were included, the rate of injury for 14-18 year olds doubled. The overall rate of injury was 122.7/10,000 workers, but was higher in the construction, manufacturing, and transportation sectors, and in the agriculture, forestry, fishing, and hunting sector for older teens and young adults. Young workers continue to be at risk for occupational injuries. Our results show that specific interventions may be needed for older teen and young adult workers to reduce their rate of injury. © 2010 Wiley-Liss, Inc.

Occupation and mesothelioma in Sweden: updated incidence in men and women in the 27 years after the asbestos ban

Hillerdal, Gunnar

2016-01-01

OBJECTIVES We updated the Swedish component of the Nordic Occupational Cancer (NOCCA) Study through 2009 in order to investigate the incidence of mesothelioma of the peritoneum and pleura in both genders, and explored occupational exposures that may be associated with mesothelioma. METHODS The Swedish component of the NOCCA Study includes 6.78 million individuals. Data from this cohort were linked to the population-based Swedish Cancer Registry and Swedish Total Population Registry for three periods between 1961 and 2009, and then further linked to the Swedish NOCCA job-exposure matrix, which includes 25 carcinogenic substances and the corresponding exposure levels for 280 occupations. Multivariate analysis was used to calculate standardized incidence ratios (SIRs) for mesothelioma of the peritoneum and pleura by gender, occupational category, carcinogenic substance, and for multiple occupational exposures simultaneously. RESULTS A total of 3,716 incident mesotheliomas were recorded (21.1% in women). We found a significantly increased risk of mesothelioma in 24 occupations, as well as clear differences between the genders. Among men, increased risks of mesothelioma of the pleura were observed in male-dominated occupations, with the greatest elevation of risk among plumbers (SIR, 4.99; 95% confidence interval, 4.20 to 5.90). Among women, increased risks were observed in sewing workers, canning workers, packers, cleaners, and postal workers. In multivariate analysis controlling for multiple occupational exposures, significant associations were only observed between asbestos exposure and mesothelioma. CONCLUSIONS Asbestos exposure was associated with mesothelioma incidence in our study. The asbestos ban of 1982 has yet to show any clear effect on the occurrence of mesothelioma in this cohort. Among women, the occupations of canning workers and cleaners showed increased risks of mesothelioma of the pleura without evidence of asbestos exposure. PMID:27866405

Occupational health nurses are familiar with health and safety standards, but may not understand or participate in the rulemaking process used to develop them. 3. Knowing the eight basic steps of rulemaking and actively participating in the process empowers occupational health nurses to influence national policy decisions affecting the safety and health of millions of workers. 4. By actively participating in rulemaking activities, occupational health nurses also improve the quality of occupational health nursing practice and enhance the image of the nursing profession.

Empirical Evidence on Occupation and Industry Specific Human Capital

PubMed Central

Sullivan, Paul

2009-01-01

This paper presents instrumental variables estimates of the effects of firm tenure, occupation specific work experience, industry specific work experience, and general work experience on wages using data from the 1979 Cohort of the National Longitudinal Survey of Youth. The estimates indicate that both occupation and industry specific human capital are key determinants of wages, and the importance of various types of human capital varies widely across one-digit occupations. Human capital is primarily occupation specific in occupations such as craftsmen, where workers realize a 14% increase in wages after five years of occupation specific experience but do not realize wage gains from industry specific experience. In contrast, human capital is primarily industry specific in other occupations such as managerial employment where workers realize a 23% wage increase after five years of industry specific work experience. In other occupations, such as professional employment, both occupation and industry specific human capital are key determinants of wages. PMID:20526448

OBJECTIVE. The present study was carried out to investigate the effects of occupational lead exposure on the hematological and biochemical parameters in occupationally exposed and non exposed inhabitants of Karachi. MATERIAL AND METHODS. In 100 lead exposed subjects recruited from automobile workshops, lead battery repair and recycling units located in Karachi and in 100 control subjects the general health status, hematological parameters and exposure markers for lead were measured. RESULTS. Results indicated that the mean values of blood lead level and delta-aminolevulinic acid were significantly higher (P<0.05) while the activity of delta-aminolevulinic acid dehydratase were significantly decreased (P<0.05) among battery repair and recycling workers as compared to controls. The abnormalities in the blood lead level, delta-aminolevulinic acid and delta-aminolevulinic acid dehydratase were more frequent in lead exposed battery repair workers when compared with control subjects. The blood lead levels and deltaaminolevulinic acid were positively correlated while delta-aminolevulinic acid dehydratase was found to be negatively correlated with age, years of exposure and years of employment. Blood lead level was positively correlated with hemoglobin and RBC count while delta-aminolevulinic acid dehydratase was negatively correlated with hemoglobin concentration. The work related symptoms, droopiness, nasal symptoms and muscular pain were more frequent among battery repair workers as compared to control group. The findings of present study confirmed that occupational exposure to lead is associated with deviation in important hematological parameters and biological markers of exposure to lead among lead exposed workers, and also confirms the impact of lead exposure in the development of adverse effects among lead exposed workers. The study provides the data for risk assessment in lead battery repair workers of Karachi and suggests the need for preventive measures for battery repair workers and improvements to reduce occupational lead exposures to protect them from lead toxicity. It is suggested that hematological and physical examinations of lead exposed workers should be carried out periodically to prevent future health hazards.

Perceived occupational exposures of home care workers and the association to general tension, shoulder-neck and low back pain.

Home care workers are at risk of various harmful occupational exposures, health complaints and sick leave. Identifying occupational exposures related to shoulder-neck and low back pain, and assessing the comparative importance of such exposures, for home care workers. One hundred and thirty-eight home care workers in a large municipality in Norway participated in the study (response rate 76.2%). Questionnaire comprised a combination of standardized items and context-specific VAS scales on mental, social, emotional and physical work demands, perceived general tension and pain in shoulder-neck and low back. Severe pain scores for both shoulder-neck and low back regions were common, with individual variations. All VAS measures on occupational exposures were significantly correlated with shoulder-neck pain and all except social demands were significantly correlated with low back pain. However, stronger associations were found with perceived general tension, which proved to be the strongest predictor of shoulder-neck and low back pain, indicating a mediating effect in the relationship between occupational exposures and musculoskeletal pain. Identifying and alleviating occupational exposures is important to ensure a healthy and sustainable work environment. Special attention should be drawn to early signs of symptoms, such as general tension, preventing further development of musculoskeletal pain.

Refugee settlement workers' perspectives on home safety issues for people from refugee backgrounds.

Refugees experience higher levels of emotional, psychological and physical distress than the general migrant population during settlement in a new country. Safety in the home can be a major concern and is an issue of which occupational therapists should be aware. Occupational therapists working with refugees in many contexts feel unprepared and overwhelmed. As refugee settlement workers attend to home safety of refugees during the settlement process, this study aimed to develop an in-depth understanding of their perceptions of this issue. Such information can contribute to occupational therapists' knowledge and practice when working with refugees. An exploratory qualitative case study approach used 16 semi-structured interviews and observation of a settlement worker assisting newly arrived refugees. Participants were settlement service staff (an occupational therapist, case coordinators and cultural support workers). Three themes are reported: considerations for safety in the homes of refugees; factors influencing home safety for refugees; and sensitivity to culture. Participants described tailoring home safety-related services to each individual based on factors that influence home safety and sensitivity to culture. Awareness of home safety issues can increase cultural competence and inform practice and policy. © 2010 The Authors.

The Occupational Cost of Being Illegal in the United States: Legal Status, Job Hazards, and Compensating Differentials1

Hall, Matthew; Greenman, Emily

2014-01-01

Considerable research and pervasive cultural narratives suggest that undocumented immigrant workers are concentrated in the most dangerous, hazardous, and otherwise unappealing jobs in U.S. labor markets. Yet, owing largely to data limitations, little empirical work has addressed this topic. Using data from the 2004 and 2008 panels of the Survey of Income and Program Participation, we impute legal status for Mexican and Central American immigrants and link their occupations to BLS data on occupational fatalities and occupational hazard data from the Department of Labor to explore racial and legal status differentials on several specific measures of occupational risk. Results indicate that undocumented workers face heightened exposure to numerous dimensions of occupational hazard – including higher levels of physical strain, exposure to heights, and repetitive motions – but are less exposed than native workers to some of the potentially most dangerous environments. We also show that undocumented workers are rewarded less for employment in hazardous settings, receiving low or no compensating differential for working in jobs with high fatality, toxic materials, or exposure to heights. Overall, this study suggests that legal status plays an important role in determining exposure to job hazard and in structuring the wage returns to risky work. PMID:26190867

Results indicate that undocumented workers face heightened exposure to numerous dimensions of occupational hazard - including higher levels of physical strain, exposure to heights, and repetitive motions - but are less exposed than native workers to some of the potentially most dangerous environments. We also show that undocumented workers are rewarded less for employment in hazardous settings, receiving low or no compensating differential for working in jobs with high fatality, toxic materials, or exposure to heights. Overall, this study suggests that legal status plays an important role in determining exposure to job hazard and in structuring the wage returns to risky work.

Today, occupational accidents are one of the most important problems in industrial world. Due to lack of appropriate system for registration and reporting, there is no accurate statistics of occupational accidents all over the world especially in developing countries. The aim of this study is epidemiological assessment of occupational accidents in Iran. Information of available occupational accidents in Social Security Organization was extracted from accident reporting and registration forms. In this cross-sectional study, gender, age, economic activity, type of accident and injured body part in 22158 registered accidents during 2008 were described. The occupational accidents rate was 253 in 100,000 workers in 2008. 98.2% of injured workers were men. The mean age of injured workers was 32.07 ± 9.12 years. The highest percentage belonged to age group of 25-34 years old. In our study, most of the accidents occurred in basic metals industry, electrical and non-electrical machines and construction industry. Falling down from height and crush injury were the most prevalent accidents. Upper and lower extremities were the most common injured body parts. Due to the high rate of accidents in metal and construction industries, engineering controls, the use of appropriate protective equipment and safety worker training seems necessary.

Despite widespread availability of assistive technology and the role of occupational therapists and audiologists in workplace health, little is known about how these groups influence the health of workers with hearing loss. Based on a previously conducted study, this paper explores the need for networking and community of practice theory to promote knowledge sharing and use between occupational therapists, audiologists, educators, regulators, workers, and employers. Five occupational therapists and five audiologists participated in in-depth interviews. Grounded theory was used to investigate the processes that hinder or support these professionals in addressing the accommodation needs of and workplace accessibility for workers with hearing loss. Constraints to addressing the needs of workers with hearing loss included: lack of knowledge about professional practice processes, lack of networking, lack of knowledge on current research, and lack of knowledge on the realm of expertise of audiologists by occupational therapists and of occupational therapists by audiologists. Innovations in workplace practice in hearing loss require engagement of occupational therapists, audiologists, and employers in knowledge transfer, networking, and learning. This column introduces two theories that may guide the use and development of evidence, knowledge, and expertise toward innovations in hearing work practice.

Objective This study aimed to summarize the major health problems among Chinese workers, the strategies and measures for occupational hazards control, the network and organizations of occupational health administration, and the achievements and current challenges of occupational health in China. Results The situation of occupational health was found to be still serious in China. Enterprises with occupational hazards were widely distributed, the exposed population and cases of occupational diseases were numerous, and occupational risks were being transferred from the city to the countryside and from developed areas to developing ones. New emerging problems coexisted with traditional occupational hazards. Besides, a lack of occupational health services for migrant workers could be a major problem for a long time. Conclusions It is necessary to improve the fields related to occupational health, such as the supervision and administration of small- and medium-scale enterprises, research into key techniques for the prevention and control of occupational hazards, systems for the diagnosis and reporting of occupational diseases, and the training of health professionals.
