Shift work and mental health: a systematic review and meta-analysis
Background: Shift work is common. However, research findings are mixed regarding the impact of shift work on mental health. This systematic review sought to provide a comprehensive summary of existing research examining the association between different types of shift work and mental health. The review included large-scale, non-occupation-specific research. Methods: Four electronic databases PubMed, PsycINFO, Web of Science and SCOPUS were searched to identify studies that reported on the statistical association between shift work and mental health and that used population-based samples. Two reviewers...
Healthy working time arrangements for healthcare personnel and patients
A systematic literature review Background: A number of working time arrangements have been linked to negative consequences for both health personnel and their patients. A common hypothesis put forth to explain these findings suggests that certain working time arrangements lead to negative patient consequences due to the adverse impact they have on employee health. The purpose of this study is to use systematic reviews to investigate whether employee health explains the relationship between working time arrangements and patient safety. Methods: A systematic literature review was performed including...
Short rest between shifts (quick returns) and night work is associated with work-related accidents
Purpose The aim of this study was to examine whether less than 11 h between shifts (i.e., quick returns, QRs) and night shifts is associated with self-reported work-related accidents, near accidents or dozing off at work in a sample of nurses. Methods The study was based on cross-sectional data from 1784 nurses (response rate = 60%; mean age = 40.1 years, SD = 8.4; 91% female). Negative binomial regression analyses were conducted to investigate the association between the shift exposures, and eight different self-reported work-related items on accidents...

Night and rotational work exposure within the last 12 months and risk of incident hypertension
Objectives: Shift work, such as alternating day and nights, causes chronobiologic disruptions which may cause an increase in hypertension risk. However, the relative contributions of the components of shift work ? such as shift type (eg, night work) and rotations (ie, switching of shift times; day to night) ? on this association are not clear. To address this question, we constructed novel definitions of night work and rotational work and assessed their associations with risk of incident hypertension. Methods: A cohort of 2151 workers at eight aluminum manufacturing facilities previously studied...
Short time between shifts and risk of injury among Danish hospital workers
A register-based cohort study Objectives: Short time between consecutive work shifts (quick returns, ie, ≤11 hours between shifts) is associated with sleepiness and fatigue, both of which have been linked to risk of injury. This paper aims to study quick returns between work shifts and risk of injury among Danish hospital workers. Method: The study population included 69 200 employees, primarily working at hospitals, corresponding to 167 726 person years at risk between 2008–2015. Information on working hours was obtained from payroll data in the Danish Working Hour Database and linked...
Impact of shift work on the diurnal cortisol rhythm
A one-year longitudinal study in junior physicians Background: Cumulative epidemiological evidence suggests that shift work exerts harmful effects on human health. However, the physiological mechanisms are not well understood. This study aimed to examine the impact of shift work on the dysregulation of the hypothalamic-pituitary-adrenal axis, i.e. diurnal cortisol rhythm. Methods: Seventy physicians with a mean age 30 years participated in this one-year longitudinal study. Working schedules, either shift work or regular schedules with day shift, were assessed at baseline. Salivary cortisol samples...
Étude des perceptions de l'environnement de travail au cours du poste chez des travailleurs postés
Pour mieux comprendre les effets du travail en horaires postés, nous avons étudié les variations des perceptions de l'environnement de travail selon le poste travaillé et la phase du poste. Le questionnaire construit, en référence au Job Content Questionnaire, mesure les perceptions de demandes, contrôle et soutien social et deux dimensions supplémentaires : les ressources techniques et humaines et les interférences travail-hors travail. Il a été renseigné à trois reprises (une heure après le début...
