“…Based on these review papers published in 1999 and 2011, few studies have examined the effect of shift work on diabetes or inflammation. Non-daytime shift work (e.g., night shift) was associated with an increased risk of hypertriglyceridemia, but the effects of non-daytime shift work on body habitus (e.g., body mass index, overweight, obese) and cholesterol were not consistently associated with each other, which is consistent with a recent (2014) epidemiological study using data from the National Health and Nutrition Examination Survey (NHANES) [3]. Recently (2014), Wang et al performed a meta-analysis among 13 studies, and concluded that night shift work is associated with an increased risk of metabolic syndrome [4], which is consistent with their other recent (2014) meta-analysis demonstrating an increased risk of breast cancer among night-shift workers [5].…”

“…Further, I chose not to statistically control for triglycerides (known to be influenced by work shift) as only a subsample of participants were tested for fasting triglycerides. And although employed in other NHANES studies [3,29], another limitation is the self-report nature of the shift work information. Major strengths of this study include the novel investigation (shift work on RDW), employing a national sample of U.S. adults, and including a comprehensive set of covariates in the analytical models.…”

“…For example, information on duration in years and frequency (e.g., how many night shifts per month) was not available. However, several publications have used measures of SW from NHANES to examine several outcomes including prostate specific antigen and metabolic syndrome (Flynn-Evans, Mucci, Stevens, & Lockley, 2013; Santhanam, Driscoll, Gress, & Khthir, 2014; Wirth, Burch, Shivappa, Steck, et al, 2014). It should be noted that differences in population characteristics were observed between those excluded due to lack of information compared with those included in the analyses.…”

Objectives Abnormal physiology (e.g., inflammation), brought on by environmental exposures (e.g., diet or shiftwork [SW]), can affect numerous bodily systems, including the brain, and may be associated with depressive symptomatology. The study examined the associations between shiftwork and depressive symptoms and diet-related inflammation (estimated by the Dietary Inflammatory Index [DII]TM) and depressive symptoms. Additionally, diet was examined as a mediator between shiftwork and depressive symptoms. Methods Data were obtained from the United States National Health and Nutrition Examination Survey (2005–2012). SW data were based on self-report. Dietary data were collected using 24-hour dietary recalls for DII calculation. Depressive symptoms were defined using a cut-point of 10 (moderate) on the Patient Health Questionnaire-9. Logistic regression was used to estimate odds ratios and 95% confidence intervals (95%CI) for depressive symptoms by SW and DII quartiles. Results DII scores were associated with depressive symptoms among women. Women in DII quartile 4 were 30% more likely to report depressive symptoms than women in quartile 1 (95%CI=1.00–1.68). There was no association between symptoms and SW when using a PHQ-9 cut-point of 10. When using a cut-point of 5 (mild depressive symptoms), those working any form of shiftwork were more likely to suffer from mild symptoms than day workers (odds ratio=1.22; 95%CI=1.04–1.43). There was some evidence for mediation by the DII between SW and depressive symptoms. Conclusions Future longitudinal studies should examine effects of reductions in inflammation through diet on depressive symptoms, especially among shiftworkers, to elucidate the role of diet on depression among these groups.

“…Three categories emerged: permanent night shifts (PN; n = 14), rotational shifts including nights (R + N; n = 28) and rotational shifts without nights (R-N; n = 4). In some cases, the type of schedule was not well explicit [14,22,28,37] or the population of SWs resulted from a combination of different schedules [15,48,50,56]. Such cases were labelled as a fourth category "Not Specified" (NS; n = 8).…”

Shift work (SW) encompasses 20% of the European workforce. Moreover, high blood pressure (BP) remains a leading cause of death globally. This review aimed to synthesize the magnitude of the potential impact of SW on systolic blood pressure (SBP), diastolic blood pressure (DBP) and hypertension (HTN). MEDLINE, EMBASE and CENTRAL databases were searched for epidemiological studies evaluating BP and/or HTN diagnosis among shift workers, compared with day workers. Random-effects meta-analyses were performed and the results were expressed as pooled mean differences or odds ratios and 95% confidence intervals (95% CI). The Newcastle–Ottawa Scale was used to assess the risk of bias. Forty-five studies were included, involving 117,252 workers. We found a significant increase in both SBD and DBP among permanent night workers (2.52 mmHg, 95% CI 0.75–4.29 and 1.76 mmHg, 95% CI 0.41–3.12, respectively). For rotational shift workers, both with and without night work, we found a significant increase but only for SBP (0.65 mmHg, 95% CI 0.07–1.22 and 1.28 mmHg, 95% CI 0.18–2.39, respectively). No differences were found for HTN. Our findings suggest that SW is associated with an increase of BP, mainly for permanent night workers and for SBP. This is of special interest given the large number of susceptible workers exposed over time.
