The proportion of obese and overweight children is alarmingly high. This dictates the need for promoting healthy lifestyle and eating habits in children. Summer camps provide a wide range of activities to improve children’s health. However, methods used to assess children’s nutritional status during a camp session need to be analyzed in depth, and a rationale should be provided for the use of bioelectrical impedance analysis (BIA) and anthropometric measurements as efficacy criteria for summer camp healthcare. We examined 125 boys and 221 girls aged 8–15 years spending their summer holidays at 3 different camps. Measurements were taken twice: on days 1 and 2 upon arrival to a camp and 2 days before leaving for home. In each camp, both positive and negative health weight dynamics were observed. The overall weight dynamics in children from camps 1 and 2 were statistically insignificant (p = 0.415 and p = 0.585), in contrast to camp 3 where those changes were significant (p = 0.025). BIA revealed that less than 44.34% of children had gained skeletal muscle mass during their stay at the camp, whereas weight loss was associated with both decreased fat and skeletal muscle masses. BIA confirms the results of anthropometric measurements and also provides information about the diet offered to children and their level of physical activity. Therefore, the use of anthropometric measurements and BIA could be an informative method for assessing the efficacy of healthcare in summer camps.

Nowadays it is essential to provide safe nutrition for population via activities aimed at reducing risks related to adverse effects produced by contaminants on people's health; such activities include those accomplished within the state sanitary-epidemiologic surveillance. As per data provided by Samara Regional Center for Hygiene and Epidemiology, 71,204 food products samples were analyzed; analysis focused on contents of heavy metals (cadmium, mercury, lead, and arsenic), pesticides (hexachlorocyclohexane or HCCH, Dichlorodiphenyltrichloroethane or DDT,) nitrates, nitrites, aflatoxin B1, and benzpyrene. Next, exposure was assessed and risks of carcinogenic and non-carcinogenic effects were calculated. Analysis of an aggregated hazard index created as per median values of contaminants contents revealed that arsenic made a substantial contribution into risks which was equal to 48 %. The second rank place belonged to cadmium that accounted for 14 %; the third one was occupied with nitrates, 12 %. The following food products groups contributed into the aggregated hazard index: melons and vegetables (23 %), bread and grocery (22 %), milk and milk products (12 %), meat and meat products (11 %), fruit and berries (9 %). It was shown that simultaneous introduction of the examined contaminants taking into account the highest non-carcinogenic risks exerted the most adverse impacts on the hormonal system due to combined exposure to cadmium, mercury, lead, arsenic, and DDT. We assessed carcinogenic risks caused by combined introduction of the contaminants taking into account their median concentrations and revealed that the risks were within the third range. We designed evolution models for carcinogenic risks basing on calculated consumption of various food products both as per median concentrations and 90%-percentile; it allowed us to assess these risks as being "negligible". It was shown that the state sanitary-epidemiologic surveillance in Samara region accomplished all the necessary activities as regards monitoring over quality and safety of food products, both domestic and imported.

Objective. Monitoring of the organization of meals and hygienic assessment of the quality of school menus in educational institutions of the Samara region. Materials and methods. Data on the organization and quality of meals in 57 secondary educational institutions of the Samara region were obtained through a sanitary and hygienic description and examination of schools, as well as a questionnaire survey of employees responsible for food. To assess the quality of school rations, an analysis of the nutritional structure was carried out, the coefficient of provision with nutrients and products was calculated, as well as the healthy eating index. Results. There were cases of realization of food and beverages prohibited for children in canteens, low coverage with two meals (10% in grades 1–9 and 3% in grades 10–11), and isolated cases of short duration of breaks for meals (15 minutes). The diet was characterized by an increased energy value (M = 1789.64 ± 138.19 kcal) and a greater excess of carbohydrates (M = 291.99 ± 12.51) due to the predominance of cereals and pasta in the meal structure. The Healthy Eating Index for students was satisfactory, owing to low consumption of fruits, dairy and seafood, and the presence of refined grains in the diet. Conclusion. The identified problems in the organization of school meals increase the likelihood of the development of alimentarydependent diseases among students. From a practical point of view, the appointment and proper hygienic training of personnel responsible for food in educational instituitons is required.

Objectives an analysis of physical and chemical indicators of milk quality produced under the most popular brands in the Samara region. Material and methods. The study was selective and prospective, focused on the physical and chemical indices of milk quality. The sampling was based on the results of the assessment of the frequency of consumption of various brands of milk by the population of the Samara region. The analysis included five samples of milk of different brands, purchased in the retail food store chain, and assessed their various physical and chemical indicators. All measurements were performed in accordance with the regulatory documentation. Results. Only 1/3 part of respondents (32.6%) included milk in their daily diet. All five milk samples subjected to physical and chemical examination met the requirements of the current regulatory documentation. However, in assessing the nutritional value of the samples by mineral composition, it was found that the actual content of phosphorus and calcium is significantly lower than the values of the corresponding indicators set out in the handbook "Chemical composition and calorie content of Russian food products" that is used as a guide by nutrition specialists. Conclusion. Milk purchased in the food store chain met the safety requirements for physical and chemical indicators. The reduced level of milk consumption among the population of the Samara region requires management decisions. The actual chemical composition of this product, which has regional and seasonal characteristics, should be taken into account in the development of diets for defined population groups.
