A new third version of the Copenhagen Psychosocial Questionnaire (COPSOQ III) has been developed in response to trends working life, theoretical concepts, and international experience. key component COPSOQ III is a defined set mandatory core items be included national short, middle, long versions questionnaire. The aim present article test reliability middle III.The questionnaire was tested among 23,361 employees during 2016-2017 Canada, Spain, France, Germany, Sweden, Turkey. total 26...
Objectives: To examine the relationship between perceived adequacy of personal protective equipment (PPE) and workplace-based infection control procedures (ICP) mental health symptoms among a sample health-care workers in Canada within context current COVID-19 pandemic. Methods: A convenience-based internet survey was facilitated through various labor organizations April 7 May 13, 2020. total 7,298 respondents started survey, which 5,988 reported information on main exposures outcomes....
This study examined trends over time in the prevalence of anxiety and depression among Canadian nurses: 6 months before, 1-month after, 3 after COVID-19 was declared a pandemic.
Abstract Objectives Prevailing job stress models encourage a multidimensional view of the psychosocial work environment and highlight role that multiple co-occurring stressors play in aetiology mental health problems. In this study, we develop latent typology profiles to describe how comprehensive array are clustered Canadian labour market. We also examine association between these several indicators health. Methods Data were collected from 6408 workers who completed National Psychosocial...
The COVID-19 pandemic has led to large proportions of the labour market moving remote work, while others have become unemployed. Those still at their physical workplace likely face increased risk infection, compared other workers. objective this paper is understand relationship between working arrangements, infection control programs (ICP), and symptoms anxiety depression among Canadian workers, not specifically in healthcare.
Abstract Objectives To validate the factor structure of Copenhagen Psychosocial Questionnaire (COPSOQ) in a North American population and dissect associations between psychosocial factors workplace psychological health safety. Methods Confirmatory analysis multivariate linear regression were used to determine COPSOQ dimensions global rating Models stratified by sex, gender roles, age. Results The was verified among Canadian workers. Three found significantly contribute safety for all Few...
There is a need for diagnostic tool with the ability to measure cumulative exposure manganese (Mn) in workplace. Measuring bone Mn levels vivo neutron activation analysis (IVNAA) could serve as biomarker of past exposure. Bone welders were measured and compared found subjects without element.Forty (30 10 controls) recruited. An occupational history was obtained underwent IVNAA measurements.The mean (2.9 +/- 0.4) (0.1 0.7) microg Mn/g Ca controls, respectively (P < 0.05).This project, first...
Elevated operating theatre noise can be hazardous to patient safety and may cause occupational stress. In a nine-hospital study, background average were measured, during operations in different subspecialties, found higher than levels recommended by the World Health Organization (WHO) for hospital areas which care takes place. nurses had also answered question about hearing ‘quiet’, ‘normal’, ‘loud’ talking, speech interference estimated indicated that other personnel substantially raise...
Background Although worker representation in OHS has been widely recognized as contributing to health and safety improvements at work, few studies have examined the role that representatives play this process. Using a large quantitative sample, paper seeks confirm findings from an earlier exploratory qualitative study can be differentiated by knowledge intensive tactics strategies they use achieve changes their workplace. Methods Just under 900 Ontario completed surveys which asked them...
In response to worker and union representative concerns, the association between metalworking fluid exposure respiratory symptoms was investigated in a cross-sectional survey, large automotive machining location. A self-administered symptom-screening questionnaire sent 2935 current employees. MWF levels were assigned respondents on departmental basis based average "peak" area aerosol measurements. exposure, years plant, smoking status regressed presence or absence of daily weekly symptoms,...
Manganese (Mn) is a nutrient essential for regulating neurological and skeletal functions in the human body, but it also toxic when humans are excessively exposed to Mn. Blood (or serum/plasma) other body fluids reflect only most recent exposure rapidly return within normal ranges, even there has been temporary excursion response exposure. In this context, we have developing non-invasive measurement of Mn stored bone, using vivo neutron activation analysis. Following feasibility studies,...
Abstract Background The education sector has been heavily impacted by COVID-19. While the impact on school-aged children received much attention, less attention focused experiences of educators. Aims To compare various dimensions psychosocial work environment and health outcomes between educators engaged in online learning to those in-person Canadian province Ontario. Methods Responses from 5438 either or were collected 23 November 21 December 2020; three months after start 2020/21 academic...
Objective: To examine longitudinal reciprocal relationships between the psychosocial work environment and burnout. Methods: We used two-wave cross-lagged panel models to estimate associations a wide range of factors (ie, job demands, control, insecurity, coworker support, supervisor organizational justice) burnout in broadly representative sample general working population Canada ( n = 453). Results: Bidirectional were observed. Results supported causal predominance over Higher lower higher...
Despite numerous studies of asbestos workers in the epidemiologic literature, there are very few cohort chrysotile miners/millers that include high-quality retrospective exposure assessments. As part creation Baie Verte Miners' Registry 2008, a two-dimensional job matrix (JEM) was developed for estimating exposures former miners/millers. Industrial hygiene data collected between 1963 and 1994 were analysed to assess validity use assessment study. Registered employees divided into 52 groups...
Objective The aim of this study was to examine the association between perceived adequacy infection control practices (ICPs) and symptoms anxiety among educators in Ontario, Canada. Methods Data from 4947 were collected December 2020. Modified Poisson models assessed ICPs moderate or severe symptoms, adjusting for a range covariates. Results Approximately 60% respondents reported symptoms. Two-thirds (66.5%) sample had less than half their ICP needs met. Respondents with met more three times...

Abstract Background Unpaid overtime—describing a situation where extra hours are worked but not paid for—is common feature of the labor market that, together with other forms wage theft, costs workers billions dollars annually. In this study, we examine association between unpaid overtime and mental health in Canadian working population. We also assess relative strength that by comparing it against those broadly recognized work stressors. Methods Data were drawn from survey administered to...
Abstract In response to a regulatory requirement develop exposure records for workers exposed silica, corporation operating two ductile iron foundries embarked on an intensive silica sampling program. Over 6-year period (1983 1988 inclusive) approximately 1000 respirable personal air samples were collected. Exposure categories initially assigned according job title. Later, criteria developed evaluate the representativeness of data in each category. To meet these category had to: have at...
