“…To make this possible, future etiological studies on shift work and health need to be based on precise and preferably repeated information on exposure combined with long, preferably registry-based follow-up. The use of register-based exposure information on working hours, like payroll data, is recommended if a sufficient proportion of working life is covered (81).…”

“…However, other studies have found that shiftwork does not influence the risk factors associated with cardiovascular disease (Yong, Germann, Lang, & Oberlinner, 2015). Importantly, although the relationship between shiftwork and cardiovascular disease has been supported by most studies, methodological concerns, such as selection bias, insufficient control, and imprecise exposure information, may explain the inconsistencies in this line of inquiry; these concerns need to be addressed in future scholarly work (Härmä, Gustavsson, & Kolstad, 2018). Relatedly, research exploring the relationship between shiftwork and ischemic heart disease has found that, when controlling for related factors such as social class, there is no significant relationship (e.g., Bøggild, Suadicani, Hein, & Gyntelberg, 1999; McNamee et al, 1996; Yadegarfar & McNamee, 2008).…”

Working 9‐to‐5? A review of research on nonstandard work schedules

2020

Summary Increasingly, organizations around the world need employees to work weekends and during hours that fall outside of a traditional 9‐to‐5, Monday through Friday, schedule. At the same time, in recent years, employees have sought more flexible working arrangements that result in longer work shifts that occur on fewer days each week. Although nonstandard work schedules have important organizational implications, much of this research has occurred outside of the management literature. Further, within the management literature, there has been little attempt to review and integrate the findings of prior studies of nonstandard work schedules. In this paper, we review research that has investigated nonstandard work shifts and how they affect work‐related outcomes (e.g., job behavior and job attitudes), health‐related outcomes (e.g., physiological, behavioral, and psychological consequences), and personal/family‐related outcomes (e.g., work–family conflict, divorce, and parent–child relations). Following our review, we identify avenues for future investigations, with a particular emphasis on methodological improvements and research that would facilitate the development of integrated conceptual models that more fully consider the implications of work schedules in the context of other important areas of organizational scholarship.

“…Associations between night shift work and increased risk of cardiovascular disease (CVD) have been observed in epidemiologic studies for decades; a recent meta‐analysis estimated that every 5 years of night shift work increases the risk of CVD by 7% . Night shift work is an integral part of many industries and occupations.…”

Background: Night shift work is associated with cardiovascular disease, but its associations with cardiovascular disease biomarkers are unclear. We investigated these associations in a study of female nurses. Methods:We used data from the Nurses' Health Study II for total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein (HDL) cholesterol, triglycerides, C-reactive protein (CRP), and fibrinogen. The sample sizes for our analysis ranged from 458 (fibrinogen) to 3574 (total cholesterol). From questionnaires, we determined the number of night shifts worked in the 2 weeks before blood collection and total years of rotating night shift work. We used quantile regression to estimate differences in biomarker levels by shift work history, adjusting for potential confounders.Results: Nurses working 1 to 4 recent night shifts had median HDL cholesterol levels 4.4 mg/dL (95% confidence interval [CI]: 0.3, 7.5) lower than nurses without recent night shifts. However, working ≥5 recent night shifts and years of rotating night shift work were not associated with HDL cholesterol. There was no association between recent night shifts and CRP, but median CRP levels were 0.1 (95% CI: 0.0, 0.2), 0.2 (95% CI: 0.1, 0.4), and 0.2 (95% CI: 0.0, 0.4) mg/L higher among nurses working rotating night shifts for 1 to 5, 6 to 9, and ≥10 years compared with nurses never working rotating night shifts. These associations were attenuated when excluding postmenopausal women and women taking statins. We observed no associations between night shift work and other biomarkers. Conclusions:We found suggestive evidence of adverse short-term and long-term effects of night shift work on select cardiovascular disease biomarkers.
