“…The effect of shift work on body weight has been investigated in previous studies, several of which demonstrated a significant tendency to become overweight [6,27,28]. In contrast, some studies failed to show such associations [15,29].…”

“…Weight gain in shift workers has been explained by several mechanisms, such as higher calorie intake, changes in dietary habits (such as eating fewer meals and more snacks) and the circadian distribution of food intake [5,6], as well as lower physical exercise and changes in sleeping habits [5].…”

“…Shift work and insufficient rest, as both are considered the main obstacle to healthy eating by respondents. Obesity has been shown to be more prevalent among shift workers and is associated with higher BMI, independently of age and work duration [5,6].

Objectives: The aim of this study was to compare nutrients intake, anthropometric, biochemical and psychiatric indices between shift working and day-time nurses. Methods: A cross-sectional comparative study was conducted in which ninety eight female nurses (55 day-time workers and 43 shift workers) from six educational hospitals of Jondi-Shapour University of medical sciences, Ahvaz, Iran were participated. A questionnaire including dietary, anthropometric, disease history and lifestyle pattern questions was completed and 3-day 24-hour recalls, Beck Depression Inventory (BDI) and Hospital Anxiety and Depression Scale (HADS) were collected. Serum hs-CRP and 25(OH)D 3 concentrations were measured by immunoturbidimetric and electrochemiluminescent immunoassay method, respectively. Anthropometric indices were measured according to World health organization standard protocol. Independent sample t and chi-square tests were used for statistical analysis. Results: There was a lower dietary intake of thiamin, riboflavin, niacin, folate, magnesium and iron in shift worker compared with day-time nurses (p < 0.05). No significant differences in serum hs-CRP concentrations, serum 25(OH)D 3 levels, vitamin D deficiency percentage, hemoglobin and hematocrite concentrations, and also anthropometric and psychiatric variables were found between two groups. Duration of exposure to sunlight was significantly higher in shift workers than in day time nurses. Engagement time in weekly physical exercise was around 11 times greater in day-time nurses compared with the shift work nurses (p = 0.001). Conclusions: This study showed that shift working is associated with some nutritional deficiencies and sedentary lifestyle among female nurses.

“…24 Pracę zmianową uznaje się za czynnik predykcyjny rozwoju otyłości, cukrzycy typu 2 i zespołu metabolicznego. [25][26][27] U osób narażonych na zmienność rytmu dobowego wykazano supresję produkcji leptyny, uznawanej za hormon sytości, oraz wzrost stężenia insuliny i glukozy w krwiobiegu. U osób chorujących na cukrzycę ograniczenie snu prowadzi do pogorszenia kontroli choroby, 28 czego powodem może być zubożenie jadłospisów pacjentów oraz spożywanie przez nich mniejszej ilości różno-rodnych pokarmów o niskim stopniu przetworzenia.…”

StreszczenieMelatonina to hormon wydzielany głównie przez szyszynkę, a odpowiadający przede wszystkim za regulację rytmu okołodobowego ludzi. Powstaje z endogennego tryptofanu, a jej przemiany obejmują 4 etapy, w przebiegu których tworzy się m.in. serotonina. Stężenie melatoniny zależne jest od wieku i warunków oświetlenia -światło niebieskie działa supresyjnie na jej produkcję. U dzieci i osób starszych stężenie melatoniny nie osiąga maksymalnych wartości. U osób dorosłych maksymalne wartości melatoniny stwierdza się pomiędzy północą a godziną 3 nad ranem. Melatonina katabolizowana jest głównie w wątrobie, wydalana wraz z moczem i kałem, a także utlenia się pod wpływem wolnych rodników tlenowych. Biodostęp-ność związku przyjmowanego drogą przewodu pokarmowego to ok. 15%. Wraz z wiekiem wydzielanie endogennej melatoniny spada, głównie za sprawą postępującego wapnienia struktur szyszynki. Do podobnych zaburzeń dochodzi także w przypadku pracy zmianowej. Rozchwianie cyklu okołodobowego może prowadzić do wielu schorzeń, w tym cukrzycy, otyłości i chorób nowotworowych, a za jeden z powodów tego stanu podaje się zaburzenia syntezy i sekrecji melatoniny, co jest przedmiotem badań naukowych.

“…In addition, the main cause of insomnia in shift workers is changes in the circadian rhythm (13,14). Antunes showed that 62% of people suffer from sleep disorders and insomnia is the most common complaint of shift workers (15). Dorrian et al concluded that shift work causes increases the body weight and this causes an increase in BMI and waist circumference.…”

Background: Today, obesity is considered as a health problem that increases the risk of some diseases. Therefore, identifying the effective factors on obesity is of great importance. Shift work is one of the indicators for increased risk of obesity in society and also shift work may cause various health problems for workers in military organizations. The current study aimed to investigate the relationship between shift work, and body mass index (BMI) and waist-hip ratio (WHR) among military personnel in 2016. Materials and Methods:This cross-sectional study was carried out on 100 male military personnel in Southern Iran in June-July 2016. The participants were divided into two groups based on their working schedule; shift work (50 personnel) and day work (50 personnel). The two groups were similar in terms of type of work. The subjects were selected through simple random sampling. The data collection tools consisted of a tape measure and a digital balance. Data analysis and comparison of BMI and WHR in the two groups were performed using descriptive statistics, one-way ANOVA, and Pearson correlation in SPSS. Results: The findings revealed that mean body weight, waist circumference, hip circumference, BMI, and WHR were higher in shift workers than day workers. The findings of the current study showed that 81.6% of shift workers had a BMI of higher than 25 kg/m 2 and 80.3% of shift workers had a WHR of higher than 0.90 m. Moreover, 86.2% of day workers had a BMI of less than 25 kg/m 2 and 83.1% of days workers had a WHR of less than 0.90 m. The Pearson correlation coefficient for BMI (r = 0.71) and WHR (r = 0.64) in shift workers were higher than day workers. Conclusions: The findings of this research showed that shift work increased the risk of overweight and obesity. Increased BMI and WHR are the cause of disease and require intervention measures (job rotation, sports activities, and avoidance of long duration of shift work) among shift workers.
