“…This fact may be related to shift workers' weight gain, since they seem to show a desynchronisation in lipid consumption during the day and a higher intake of this macronutrient through foods such as snacks. Associated with changes regarding eating pattern, sleep deprivation may contribute to the acceleration or triggering of metabolic disturbances, such as glucose intolerance, insulin resistance and dyslipidaemia (58) . Besides that, genes regulate body weight and food intake.…”

Obesity and shift work: chronobiological aspects

The present review has the objective of summarising chronobiological aspects of shift work and obesity. There was a systematic search in PubMed databases, using the following descriptors: shift work; obesity; biological clock. Shift work is extremely frequent in several services and industries, in order to systematise the needs for flexibility of the workforce, necessary to optimise productivity and business competitiveness. In developing countries, this population represents a considerable contingent workforce. Recently, studies showed that overweight and obesity are more prevalent in shift workers than day workers. In addition, the literature shows that shift workers seem to gain weight more often than those workers submitted to a usual work day. In conclusion, there is considerable epidemiological evidence that shift work is associated with increased risk for obesity, diabetes and CVD, perhaps as a result of physiological maladaptation to chronically sleeping and eating at abnormal circadian times. The impact of shift work on metabolism supports a possible pathway to the development of obesity and its co-morbities. The present review demonstrated the adverse cardiometabolic implications of circadian misalignment, as occurs chronically with shift workers.

“…While the immediate risk for shift workers includes heightened fatigue, disturbed sleep, and increased accident risk (3,4), prolonged shift work has also been associated with long-term adverse health issues. Shift workers are prone to obesity (5)(6)(7)(8)(9) and associated co-morbidities such as diabetes (5,6,8), high cholesterol (7-10), cardiovascular disease (5,6,11,12), gastrointestinal problems (5,6,13), and metabolic disturbances (5,6,(14)(15)(16). In addition, shift workers have an increased risk for coronary heart disease and stroke with mortality rates being highest among workers with the longest history of shift work (17)(18)(19)(20).…”

Shortened sleep and circadian misalignment, as seen in shift workers, has adverse metabolic and behavioral consequences which lead to obesity and associated comorbidities. This study demonstrates a simulated night shift enhances preference for high fat foods, which may be a contributing factor for shift work-related weight gain. Increasing awareness of changes in food preference may promote healthier food choices.

Enhanced preference for high-fat foods following a simulated night shift. Scand J Work Environ Health. 2015;41(3):288-293. doi:10.5271/sjweh.3486 Objectives Shift workers are prone to obesity and associated co-morbidities such as diabetes and cardiovascular disease. Sleep restriction associated with shift work results in dramatic endocrine and metabolic effects that predispose shift workers to these adverse health consequences. While sleep restriction has been associated with increased caloric intake, food preference may also play a key role in weight gain associated with shift work. This study examined the impact of an overnight simulated night shift on food preference.Methods Sixteen participants [mean 20.1, standard deviation (SD) 1.4 years; 8 women] underwent a simulated night shift and control condition in a counterbalanced order. On the following morning, participants were provided an opportunity for breakfast that included high-and low-fat food options (mean 64.8% and 6.4% fat, respectively). ResultsParticipants ate significantly more high-fat breakfast items after the simulated night shift than after the control condition [167.3, standard error of the mean (SEM) 28.7) g versus 211.4 (SEM 35.6) g; P=0.012]. The preference for high-fat food was apparent among the majority of individuals following the simulated night shift (81%), but not for the control condition (43%). Shift work and control conditions did not differ, however, in the total amount of food or calories consumed.Conclusions A simulated night shift leads to preference for high-fat food during a subsequent breakfast opportunity. These results suggest that food choice may contribute to weight-related chronic health problems commonly seen among night shift workers.Key terms diet; dietary intake; eating; food; habit; health; night duty; night work; nutrition; obesity; shift work; shift worker; sleep loss; weight gain.

RESUMO A formação do profissional médico impõe modificações nocivas ao estilo de vida, predispondo ao ganho de peso. O objetivo deste estudo foi realizar uma revisão acerca das prevalências de sobrepeso e obesidade e possíveis fatores causais destas taxas em estudantes de Medicina (EM) e médicos residentes (MR). Realizou-se uma busca nas bases de dados on-line-Nutritional Status.-Food Habits.-Sedentary Lifestyle.-Sleep Deprivation.-Medical Education. ABSTRACT The training of the medical profession imposes harmful changes to lifestyle, which predisposes to weight gain. The aim of this study was to review the prevalence of overweight and obesity and possible causative factors in these rates in medical students (MS) and residents physicians (RP). We conducted a search of the databases online: PubMed / Medline (U.S. National Library of Medicine), Scieloand Lilacs with the keywords: "medical students" and "residents" associated with each of the terms: "body mass index (BMI)", "obesity", "overweight", "food intake", "sendentarism" and "sleep", and using
