ABSTRACT Introduction Raynaud's phenomenon (RP) is linked to occupational exposures such as vibration, cold temperature, and chemicals. However, large cohort studies examining RP by occupation sex are scarce. To address this gap, study aimed assess risk of both in a workers Ontario, Canada. Methods Workers with accepted lost‐time compensation claims were physician billing records identify diagnoses between 2002 2020. A 3‐year washout (disease‐free) period was applied, follow‐up limited 5...

Abstract Background The disproportionate impact of coronavirus disease (COVID-19) on healthcare workers has been highlighted; however, there is a lack evidence regarding other high-risk occupations and industries. Aims This study estimated the risk severe COVID-19 among large cohort in Ontario, Canada. Methods used 1.2 million identified using workers’ compensation claims records (1983-2019). Identified were linked with emergency department (ED) visits hospitalizations (2020-2021). Cases...

Firefighters and police often work in high-stress, complex environments with known suspected carcinogenic exposures. We aimed to characterise cancer incidence among firefighters police.

Abstract As there are no well‐established modifiable risk factors for prostate cancer, further evidence is needed on possible such as occupation. Our study uses one of the largest Canadian worker cohorts to examine occupation, industry, and cancer assess patterns rates. The Census Health Environment Cohort (CanCHEC) was established by linking 1991 Cancer Database (1969–2010), Mortality (1991–2011), Tax Summary Files (1981–2011). A total 37,695 cases were identified in men aged 25–74 based...

The recently established Occupational Disease Surveillance System (ODSS) was used to examine breast cancer risk in women and men by occupation industry.Ontario workers the ODSS cohort (1983-2016) were followed up for diagnosis through Ontario Cancer Registry. Cox-proportional hazard models calculate age-adjusted ratios (HRs) 95% confidence intervals (CIs).A total of 17 865 492 cases identified working (W) (M), respectively. Elevated risks observed management (W: HR = 1.54, CI 1.40-1.70; M:...

Abstract Although several occupational exposures have been linked to the risk of COPD; limited data exists on sex-specific differences. This study aimed identify at-risk occupations and sex differences for COPD risk. Cases were identified in a large surveillance system established through linkage former compensation claimants’ (non-COPD claims) physician visits, ambulatory care data, hospital inpatient (1983–2020). Cox proportional hazard models used estimate ratios (HRs) corresponding 95%...

Although a significant body of evidence has attributed certain occupational exposures with leukemia, such as benzene, formaldehyde, 1,3-butadiene and ionizing radiation, more research is needed to identify work environments at increased risk for this disease. Our study aimed industry groups associated an elevated incidence leukemia using diverse cohort workers’ compensation claimants from Ontario, Canada. A total 2,363,818 workers in the Occupational Disease Surveillance System (ODSS)...

Carpal tunnel syndrome (CTS) is a prevalent cumulative strain injury associated with occupational risk factors such as vibration, repetitive and forceful wrist movements, awkward postures. This study aimed to identify Ontario workers at elevated for CTS explore sex differences in among workers.

Previous Canadian epidemiologic studies have identified associations between occupations and prostate cancer risk, though evidence is limited. However, there are no well-established preventable risk factors for cancer, which warrants the need further investigation into occupational to strengthen existing evidence. This study uses occupation information from a large surveillance cohort in Ontario that linked workers' compensation claim data administrative health databases.

<h3>Objective</h3> Prostate cancer continues to be the most commonly diagnosed in men, and there is limited knowledge on its preventable risk factors. A number of occupational exposures natural resource-based industries are suspected related prostate risk. This study investigates associations between employment these cancer. <h3>Methods</h3> Data were from a population-based, case–control previously conducted Northeastern Ontario. Incident cases (N=760) aged 45–85 years with 1995 1998...

Background While it is well-established that occupational exposures significantly contribute to the risk of developing lung cancer, there remains a notable gap in understanding specific sex differences cancer risk, particularly among female workers. This study aimed examine across various occupations, with an emphasis on workforce. Methods A cohort approximately 2.37 million workers lost-time compensation claims were linked Ontario Cancer Registry and followed until diagnosis, age 85,...

<h3>Objectives</h3> Mining workers in Canada may be exposed to several potential carcinogens including crystalline silica, various metals, and diesel exhaust. This study aimed assess the risk of cancer among male mining employed Canadian sectors. <h3>Method</h3> The Cohort was created by Statistics through linkage 1991 Census (long form) Mortality Database, Cancer Registry, annual Tax Summary Files (1991–2006). resulted a cohort 1.1 million working males aged 25–74, over 14 000 industry. Cox...

In Ontario, there are significant geographical disparities in colorectal cancer incidence. particular, the northern region of Timiskaming has highest incidence Ontario while southern Peel displays lowest. We aimed to identify non-nutritional modifiable environmental factors that may be associated with its diverging rates when compared Peel.We performed a systematic review established and proposed incidence, created an assessment questionnaire tool regarding these exposures, applied this...

Abstract Background While occupational exposures are known to contribute lung cancer risk, there is less about sex differences, specifically regarding the risk among female workers. This study aimed explore differences in across groups, with a focus on Methods A cohort of approximately 2.37 million workers lost-time compensation claims were linked Ontario Cancer Registry and followed until diagnosis, age 85, emigration, death, or end follow-up (Dec 31, 2020). Cox proportional hazards models...

Abstract Introduction Much attention has been focused on identifying cancer risks among firefighters and little other emergency service workers. We investigated paramedics in Ontario, Canada, compared their results to patterns observed police. Methods This study used the Occupational Disease Surveillance System; 2.37 million former worker’s compensation claimants linked Ontario Cancer Registry. Cox proportional hazard models were calculate sex age-adjusted ratios (HRs) 95% confidence...

Working-age individuals have been disproportionately affected by the opioid crisis, prompting interest in potential role of occupation as a contributor. This study aimed to estimate risk opioid-related poisonings and mental behavioural disorders industry within cohort 1.7 million formerly injured workers.

Prior analyses of the Occupational Disease Surveillance System (ODSS) have compared cancer rates using internal referent groups. As an exploratory analysis, we sought to estimate risk general population reference evaluate impact that comparison has on findings from our surveillance program.

<h3>Objectives</h3> Although epidemiological studies have generally shown inconsistent findings for prostate cancer risk and occupation, some associations with firefighting been observed. Firefighters are exposed to harmful substances that include known carcinogens. This meta-analysis aimed synthesise the available published evidence on in firefighters. <h3>Methods</h3> A comprehensive search of PubMed Web Science was conducted all English from 1980–2017. Studies reported estimates incidence...
