Aim. The aim of this study was to assess eating behavior in the groups of women who are working on different, unchanged shifts as well as identifying differences in the consumption of nutrients that may increase the risk of cardiovascular disease.Material and Methods. The study was carried out among 300 randomly selected women working in a permanent shift (morning, afternoon, night). In the study, the assessment of the daily intake was carried out using 24-h dietary recall. Anthropometric measurements were carried out to assess the nutritional status. The interview regarding the food consumption was complemented by dietary questionnaire about selected lifestyle parameters contributing to the development of cardiovascular disease and the type of their work.Results. The body mass index (BMI) in all groups was within the adequate values. The analysis of waist to hip ratio (WHR) showed that in the morning and night shift, was exceeded the adequate values recommended in the prevention of cardiovascular disease (WHR = 0.83 ± 0.1 in both groups). The analysis of the daily food rations of women revealed disparities regarding nutritional recommendations. Statistically significant differences in protein and saccharose intake were observed (p > 0.05). The average vitamin D content in the daily food rations of women was insufficient (average 1.4 µg per day); however, it was not statistically significant.Conclusions. The shift work system was influence on eating behaviors in study women. In particular in women which were worked on the night shift, which may contribute to the development of cardiovascular disease in the future.

Introduction: Currently, 10% of the Brazilian population is more than 60 years old. Calcium is an essential element to the body, it is produced endogenously and only acquired through daily intake of foods that contain it. The inadequate intake of this nutrient increases the risk of osteoporosis, as well as other diseases, such as hypertension and colon cancer. Therefore, the present study had the objective of evaluating the consumption of dietary calcium by active and sedentary elderly in the city of Santos/SP- Brazil. Methods: Seventy elderly people of both genders were evaluated, on an average age of 69 and 75 years old for active and sedentary groups respectively. For nutritional assessment, we used 24-hour Dietary Recall and the quantification of calcium intake was done by software Avanutri 4.0. Weight, height and Body Mass Index (BMI) were measured for the assessment of body composition. Results: The data of calcium intake were compared with the recommendations advocated by DRI, which is of 1,200mg/day. Both groups consumed lower amounts of the recommended. However, the group of active elderly had a greater consumption (625,3 and 546,1mg for men and women respectively) in relation to the group of sedentary elderly (517,9 and 501,5mg for men and women, respectively), but there was no statistical difference between the groups. The low consumption may reflect on bone health and other bodily mechanisms of the evaluated groups. Therefore, nutritional education work is indispensable to inform the population.

Abstract Background The shift-night work concerns around 17% workers in our modern society with evident need of this type of organisation for productivity and economic reasons for the companies. if the impact of this global organisation pattern on cardiovascular disease or risk factors is more and more documented, it remains unclear which types of rotating or night work are really involved and which are the impact on cardiovascular risk of being exposed currently or in the past to these different types of shift-night work. Purpose To study possible relationships between arterial blood pressure, anthropometric markers, fasting biomarkers, and sleep disturbances, and different exposure profiles of night work and/or shift work. Methods A cross-sectional study was conducted among 65.126 workers aged 18–70 at baseline in the French random population-based Constances cohort. Four exposure groups were defined: (1) workers with current permanent night work, (2) current night shift workers 3x8, (3) day workers with past night and/or shift work, (4) day workers without night and/or shift work during their work history (reference group). Logistic regression models adjusted for age, sex, socio-economic position, and personal history of ischemic cardiovascular disease (CVD) were performed to assess associations between clinical risk markers for CVD at baseline and these exposure groups. Results Compared with the reference group, current and past night workers had a significant higher risk of obesity (Body Mass Index≥30). Permanent night workers had a significant higher risk of metabolic syndrome, mostly due to abdominal obesity, hypertriglyceridemia (>1.7 mmol/l) and low level of high density lipoprotein. Even if day workers with past night/shift work had no statistically significant over-risk of metabolic syndrome, they presented significantly higher risks for the same three criteria as observed for the permanent night workers. However, only hypertriglyceridemia was significantly more frequent among 3x8 workers. Among current night workers, 3x8 had a higher risk of sleep disturbances while permanent had not. Sleep disturbances over-risk was also observed among day workers with past night/shift work. No over-risk of hypertension, hypercholesterolemia, hyperglycemia, and elevated levels of gamma-glutamyl-transferase was observed among the three groups. Conclusion The results support the need for enhanced cardiovascular follow-up of workers exposed to night and/or shift work. However, it is also necessary to follow regularly and specifically current day workers with a past night and/or shift work history.

AbstractUp to 20% of the population in industrialised countries are employed as shift workers. Shift work is an independent risk factor for metabolic diseases, such as type-2 diabetes, cardiovascular disease (CVD) and obesity. This may be associated with shift workers’ typical habit of eating during the night, as it forces the body to process nutrients when the body is expecting a period of fast. This study aimed to examine whether redistributing meal times, to create a defined overnight fast period, can improve CVD risk factors in night shift workers.Eligible participants were permanent or rotating night shift workers who habitually ate on night shift between 1am to 6am and had abdominal obesity as assessed by waist circumference, but were otherwise healthy. This randomised crossover trial comprised a four-week control period and a four-week intervention period separated by a minimum two-week washout period. During the intervention period, participants were advised to rearrange meal and snack times to create a five hour nightly fast between 1am and 6am. Up to four random 24-hour food recalls per participant were performed during both periods of the study, to check compliance and to assess energy intake. All recall periods included a night shift. Participants attended the research facility at the end of each period to be weighed (seca, gmbh & co. kg, Hamburg, Germany). Work schedule and meals were standardised 24 hours prior to attending the research facility. Data were analysed using paired t-test and reported as mean (SD).Participants (n = 19) were aged 41(10) years. Daily energy intake was not markedly different between the two study periods, intake was 10633 (3591) kJ/ day in the intervention period vs. 10919 (4276) kJ/ day in the control period (n = 60 recalls in each period, p = 0.670). Body weight was significantly lower at the end of the intervention period compared with at the end of the control period (86.2 (17) vs. 87.1 (18) kg, p = 0.001). Similarly, BMI was lower at the end of the intervention period compared with end of control period (30.7 (6) vs. 31.1 (6) kg/m2, p = 0.001).Increasing evidence indicates that working night shifts potentiates weight gain. We show that advising shift workers to avoid eating during 1am and 6am for a four-week period had a positive impact on body weight. Manipulating meal and snack times for shift workers may be a simple strategy to assist in weight management.

Adequately balanced daily food rations that provide the body with sufficient amounts of energy and nutrients, including minerals, are particularly important in early childhood when rapid physical, intellectual and motor development takes place. Cow’s milk (CM) and young-child formulas (YCFs) are introduced to a child’s diet past the first year of age. The main aim of the present study was to perform a qualitative and a quantitative analysis of daily food rations of young children based on the recommendations of the daily food ration model. An attempt was also made to determine whether the type of consumed milk (YCF or CM) adequately meets young children’s energy demands and contributes to the incorporation of different food groups into a balanced and healthy diet for children aged 13–24 months. A total of 714 parents between October 2019 and March 2020 filled out a food frequency questionnaire. In the second stage of the study, the parents participated in a dietary recall and were asked to keep diaries of all meals and foods consumed by children over a period of three days. The mean daily intake of CM/YCF and fermented milks was determined at 360 mL ± 128 mL, and it accounted for 55.4% of the guideline values. Flavored dairy products were consumed more frequently than fermented milks without added sugar or flavoring (94 ± 17 g vs. 56 ± 26 g, p < 0.05). Diets incorporating CM were significantly more abundant in protein than YCF diets (29.3 g vs. 21.9 g; p < 0.01). Liquid intake was somewhat higher in children fed YCFs (1280.8 mL vs. 1120.1; p < 0.05), mainly due to the higher consumption of fruit juice, nectars and sweetened hot beverages (246 ± 35 mL in the YCF group vs. 201 ± 56 mL in the CM group; p < 0.05). Children fed YCF consumed significantly larger amounts of sweetened beverages such as tea sweetened with sugar or honey, sweetened hot chocolate or instant teas (OR = 2.54; Cl: 1.32–3.26; p < 0.001), than children receiving CM. This group was also characterized by higher consumption of sweetened dairy products, mainly cream cheese desserts, fruit yogurt and yogurt with cereal (OR = 1.87; Cl: 1.36–2.54; p < 0.01), as well as a lower daily intake of plain fermented milks (OR = 0.56; Cl: 0.21–0.79; p < 0.001). The daily food intake and the quality of the diets administered to children aged 13–24 months were evaluated and compared with the model food ration. It was found that milk type influenced children’s eating habits and preference for sweet-tasting foods. The study also demonstrated that Polish parents and caregivers only have limited knowledge of nutritional guidelines for toddlers.

Introduction. Increased nervous and emotional loads in doctors of children's medical organizations are caused by frequent stressful effects, shift work mode. The study of the features of the formation of the functional state of the body of surgeons will make it possible to scientifically justify measures to prevent overstrain to preserve the health of employees. The aim of study is to research the functional state of the body of doctors of children's medical organizations with a shift work schedule to justify and develop measures for physiological and hygienic optimization of work. Materials and methods. Complex physiological and hygienic studies included occupational analysis of labor activity, physiological studies of the state of the Central nervous system (CNS) and the cardiovascular system with the study of the features of response to functional loads (ECG recording on a 12-channel electrocardiograph and continuously using Holter monitoring). Results. The study of the features and degree of adequacy of the cardiovascular system's response to dosed physical activity revealed the tension of the regulatory mechanisms of the circulatory system with a pronounced increase in heart activity in surgeons during night hours. Conclusions. Stable indicators of CNS functions (concentration of attention, etc.) were established during various shifts, due to the requirements of the work itself, adverse changes in the cardiovascular system, more pronounced during the night shift, deterioration of ECG changes to functional load, which indicates a decrease in the functional capabilities of the myocardium.

The purpose of this article is to provide background information and the current understanding of a less familiar cause of female breast cancer; exposure to ultraviolet light at night. Breast cancer is a common disease that causes significant morbidity and mortality in women. There are several risk factors for breast cancer, most of which are genetic and environmental in nature. An often-overlooked risk factor is exposure to blue light during night shift work, which decreases melatonin production. One of the many cancer-preventing properties of melatonin is to limit estrogen production. Increased lifetime exposure to estrogen is a well-known cause of breast cancer. Awareness of nighttime blue light exposure as a breast cancer risk factor by women doing night shift work and those exposed to nighttime light via smartphones and laptops, is essential information to know so that protective measures can be taken.
