Abstract

In developing countries, shift work represents a considerable contingent workforce. Recently, studies have shown that overweight and obesity are more prevalent in shift workers than day workers. In addition, shift work has been associated with a higher propensity for the development of many metabolic disorders, such as insulin resistance, diabetes, dislipidemias and metabolic syndrome. Recent data have pointed that decrease of the sleep time, desynchronization of circadian rhythm and alteration of environmental aspects are the main factors related to such problems. Shortened or disturbed sleep is among the most common health-related effects of shift work. The plausible physiological and biological mechanisms are related to the activation of the autonomic nervous system, inflammation, changes in lipid and glucose metabolism, and related changes in the risk for atherosclerosis, metabolic syndrome, and type II diabetes. The present review will discuss the impact of shift work on obesity and metabolic disorders and how disruption of sleep and circadian misalignment may contribute to these metabolic dysfunctions.

  • Combined systemic and liver metabolic disorders are frequently observed among human night-shift workers.

    “Such combined systemic and liver metabolic disorders are also frequently observed among human night-shift workers (Zimberg et al., 2012).”

    From Circadian Homeostasis of Liver Metabolism Suppresses Hepatocarcinogenesis (2016) · cites this paper as Zimberg et al., 2012

  • Circadian misalignment has been observed in chronic jet lag and night shift workers, who exhibit lowered glucose and lipid tolerance, increased liver lipogenesis, higher BMI, and are prone to various metabolic diseases such as obesity, CVD, gastrointestinal disorders, and T2DM.

    “Circadian misalignment has been observed in chronic jet lag and night shift workers, who exhibit a lowered glucose and lipid tolerance, increased liver lipogenesis, higher body mass index (BMI), and are prone to various metabolic diseases such as obesity, CVD, gastrointestinal disorders, and T2DM [258,259,260].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
