Assessing occupational styrene exposure in the European and US Glass Reinforced Plastics Industry for the period between 1947 and 2020.

Background: We aimed to develop a method for assessing occupational styrene exposures for application in epidemiological studies on risks of lymphohematopoietic neoplasms and other malignant and non-malignant diseases in the European and the US glass reinforced plastics industries.

Method: We estimated a linear mixed effects model based on individual airborne personal measurements of styrene from the glass reinforced plastics industry in Denmark, Norway, Sweden, UK, and the US. The most suitable model was chosen based on its predictive power as assessed using cross validation with different combinations of predictors; and by comparing their prediction errors.

COVID-19 risk by work-related factors: pooled analysis of individual linked data from 14 cohorts.

Background: SARS-CoV-2 infection rates vary by occupation, but the association with work-related characteristics (such as home working, keyworker or furlough) are not fully understood and may depend on ascertainment approach. We assessed infection risks across work-related characteristics and compared findings using different ascertainment approaches.

Methods: Participants of 14 UK-based longitudinal cohort studies completed surveys before and during the COVID-19 pandemic about their health, work and behaviour.

Primary and secondary allostatic processes in the context of high-stress work: A multigroup moderation from the English longitudinal study of ageing.

Evidence suggests that chronic cortisol excess may precede the development of an allostatic load, and that this association may be influenced by the level of work stress. This study aims to investigate the associations between hair cortisol concentration and the development of systemic allostatic load cross-sectionally and at a lag of four years, stratified by level of effort-reward imbalance. The sample consisted of respondents from the English Longitudinal Study of Ageing (ELSA) who were in employment with hair cortisol measurements at baseline (wave 6), and allostatic load markers at baseline and follow-up (wave 8; n=411; 64 % female).

Nightshift Rotation Schedule and Fatigue in U.K. and Italian Nurses.

Background: Whether hours on shift might impact adaptation to night shift work is still controversial.

Methods: We conducted a pooled analysis of two studies, including 170 hospital nurses working night shifts, 116 from a United Kingdom study working 12-hour rotating shifts, and 54 from Italy working 8-hour shifts. Both studies used the Epworth Sleepiness Scale (ESS) to detect sleepiness during routine daytime activities as an indicator of fatigue.
