OBJECTIVES: This study investigates the associations between the Danish version of a job exposure matrix for COVID-19 (COVID-19-JEM) and Danish register-based SARS-CoV-2 infection information across three waves of the pandemic. The COVID-19-JEM consists of four dimensions on transmission: two on mitigation measures, and two on precarious work characteristics. METHODS: The study comprised 2 021 309 persons from the Danish working population between 26 February 2020 and 15 December 2021. Logistic regression models were applied to assess the associations between the JEM dimensions and overall score and SARS-CoV-2 infection across three infection waves, with peaks in March–April 2020, December–January 2021, and February–March 2022. Sex, age, household income, country of birth, wave, residential region and during wave 3 vaccination status were accounted for. RESULTS: Higher risk scores within the transmission and mitigation dimensions and the overall JEM score resulted in higher odds ratios (OR) of a SARS-CoV-2 infection. OR attenuated across the three waves with ranges of 1.08–5.09 in wave 1, 1.06–1.60 in wave 2, and 1.05–1.45 in those not (fully) vaccinated in wave 3. In wave 3, no associations were found for those fully vaccinated. In all waves, the two precarious work dimensions showed weaker or inversed associations. CONCLUSIONS: The COVID-19-JEM is a promising tool for assessing occupational exposure to SARS-CoV-2 and other airborne infectious agents that mainly spread between people who are in close contact with each other. However, its usefulness depends on applied restrictions and the vaccination status in the population of interest.

to obtain mortality and cancer registration data for the cohort. The intention is to produce SMRs and SIRs and, where sufficient number of events allow, subanalyses including by cumulative exposure will be undertaken. Results & ConclusionThe international study will be statistically the most powerful study to have examined the carcinogenicity of styrene to date. As well as cohorts from the UK, the updated study will include cohorts from Denmark, Finland, Italy, Norway, Sweden and the USA.

Introduction Hypertension a leading cause for cerebro-cardiovascular diseases. However, a positive lifestyle could potential modify the risk of hypertension. Despite, reports on the positive association between sedentary work life and hypertension/prehypertension, studies involving blue collar workers are scarce. Current multi-cantered study investigated the cross sectional prevalence of prehypertension and hypertension among a group of blue collar (construction) workers. Methods Present cross sectional quantitative multi-centre study (Ahmedabad & Bengaluru) was executed after later to receiving Institute human ethics committee approval. Details on basis demographics and substance use was collected from all consenting construction labourers employed at construction sites. Blood pressure and Body Mass Index (BMI) were measured using standard protocols. R software was used to collect, record and clean the data. Results A total of 1253 construction workers with mean (SD) age of 28.6 (9.6) years and 92% males consented to participate. About 46.7% and 30% respectively reported of tobacco and alcohol usage. The prevalence of pre-hypertension and hypertension was estimated as 39.3% and 11.1% respectively. Factors such as age, substance use, average work hours per day and BMI significantly increased the risk for hypertension. Conclusion Interestingly the prevalence of prehypertension among these blue collar workers was high, despite the labour intensive nature of work and relatively young age. Current observations suggest the need for further investigations, strengthen the ongoing screening and intervention programs by the public health policy makers.
