“…For example, studies have found that night shift workers are not exercising less than the general population. 9 They may even be exercising more than their day-shift counterparts. 9,10 A growing body of research suggests that discordance with the circadian rhythm is an independent risk factor for the development of metabolic syndrome.…”

In this highly digitalized era, sleep disorders are becoming more common and are associated with an increased burden of chronic disease. Shift workers are at an increased risk for both sleep disorders and metabolic syndrome. In this article, the authors outline the connection between circadian discordance, hormonal imbalance, and the development of metabolic syndrome in shift workers. Based on a literature review of animal model studies, observational studies, and clinical trials conducted between August and October of 2018, the authors offer several clinical interventions, including work schedules, light therapy, medications, and dietary habits to improve the circadian synchronicity of shift workers and reduce their risk of morbidity and mortality. It is important for physicians to be familiar with the consequences of shift work and ways to mitigate the risks for this patient population. M any of the human body's neurohormonal cascades, including key metabolic cascades and the sleep-wake cycle, follow 24-hour rhythms. These circadian rhythms evolve in response to a light-dark cycle established by sunrise and sunset along with the daily rhythm of other external factors, such as temperature and noise.Today, people are exposed to synthetic light, heat, and other stimulating cues that do not follow a 24-hour cyclic pattern. These synthetic factors interfere with the carefully coordinated interplay between external regulators and the endogenous maintenance of circadian rhythms. 1 Shift workers are increasingly affected by this phenomenon. 2 This discordance among shift workers has been linked to disruption in the sleep-wake cycle and metabolic pathways, leading to sleep deprivation and an increased risk of metabolic syndrome. 3In this review, we discuss the relationship between metabolic syndrome and shift work. We completed PubMed searches in August and October 2018 using the following keywords: "shift worker demographics," "metabolic syndrome and shift workers," "risk factors associated with metabolic syndrome in shift work," "circadian rhythm and shift work," "cortisol release and shift work," "shift work and exercise habits," "shift work and nutrition habits," "circadian rhythm discordance and metabolic syndrome," "sleep hygiene and shift work disorder," "nutrition and sleep hygiene," "exercise and cortisol release," "sleep disorders and shift work," "sleep disorders and metabolic syndrome," "osteopathic manipulation and sleep latency," "shift work and heart rate variability," and "osteopathic manipulation and heart rate variability." Of the literature reviewed, 38 articles were experimental studies (animal model or clinical trials), 35 were review articles, and 17 were observational studies. Based on this literature

“…Therefore, in cross-sectional studies, the difference observed in the physical activity between day and night workers was likely to have been confounded by participants' personal characteristics. Lately, several studies utilizing objective measurement of physical activity documented no association between shift work and total leisure-time physical activity (19)(20)(21)(22).…”

We combined objective working hour data with surveys on physical activity over 17 years. Compared with day work, shift work without night shifts was associated with physical inactivity among men, whereas shift work with night shifts was negatively associated with physical inactivity among women and white-collar workers. Having small children was a risk factor for physical inactivity among shift workers.

“…Based on the results of the current study, we found no evidence that physical activity is an underlying mediator linking shift work and ILI/ARI incidence rate. As found earlier, physical activity levels of shift and non-shift workers during leisure were similar, but shift workers were more physically active at work (18). However, an association between physical activity and ILI/ARI incidence rate, and thus the association between mediator and outcome, was lacking.…”

“…Potential mediators: sleep, physical activity, and diet. To determine sleep and physical activity levels, participants were instructed to wear triaxial accelerometers (Actigraph GT3X devices, Actigraph, Pensacola, FL, USA) that were taped to their thigh, for 24 hours/day, for seven consecutive days (18). During these days, participants kept a diary in which work, sleep, and non-wear times were reported.…”

“…This measure was dichotomized as fairly/very poor versus fairly/very good sleep quality. To determine physical activity levels, time spent in the different physical activity types during waking hours was assessed with the accelerometer data and expressed as percentage of the total time (18). Percentages of walking, running, stairclimbing, and cycling were combined to form one measure for physical activity during leisure and one measure for physical activity at work.…”

The mediating role of sleep, physical activity, and diet in the association between shift work and respiratory infections

The mediating role of sleep, physical activity, and diet in the association between shift work and respiratory infections by Loef B, van der Beek AJ, Hulsegge G, van Baarle D, Proper KI In this study among healthcare workers, the association between shift work and an increased incidence rate of respiratory infection episodes was mediated by poorer perceived sleep quality among shift workers. To prevent respiratory infections in shift workers, it may therefore be relevant for future intervention research to focus on strategies to improve perceived sleep quality.
