RESUMO
Currently, there is a decrease in the total number of organizations for summer recreation of children in the country while the share of organizations of group II of sanitary and epidemiological well-being among them remains at a consistently high level that determines the potential risk of harm to the health of the child population. At the same time, there is an increase in the number of children with a pronounced health-improving effect. So, it becomes necessary to analyze the information content of modern criteria for assessing the effectiveness of health improvement and to search for ways to resolve the noted contradictions. OBJECTIVE: Analysis and scientific and methodological substantiation of modern criteria for assessing the effectiveness of children's health improvement in recreation organizations (camps). MATERIAL AND METHODS: An analysis of the literature data, our own research results' systematization and effectiveness assessment of the health improvement of 195 children aged 10 to 15 years (112 girls and 83 boys) belonging to I and II health groups and vacationers in the inpatient organization of the Samara region in the 2019 summer campaign were carried out. Anthropometric, physio-metric, and bio-impedance metrics were studied in two stages (on the 1st or 2nd day of arrival and 1 day before the camp leaving). In a comparative analysis the differences were considered significant when p<0.05. RESULTS: Stationary rest and recreation organizations in the all-Russian structure of recreation organizations for children account for 5.8%. During staying in the camp, there was a significant decrease in the proportion of girls with underweight (p=0.039); among boys no significant changes were found. The general trend towards a change in the level of physical development is not statistically significant. Bio-impedance analysis revealed only 51.3% of children with changes in indicators characterizing the health-improving effect. The tendencies to change in the proportion of children with different levels of arm muscle strength and lung capacity during the staying in then camp are statistically significant. Correlations were established between muscle strength with basal metabolism (r=0.86) and muscle mass (r=0.86), as well as negative links between average strength and the percentage of adipose tissue (r= -0.52). During the staying in the camp, the 4 cases of acute respiratory infections were registered that did not affect the assessment of the recovery effectiveness. CONCLUSION: In order to assess the health-improving effect among children during one trial in the camp, the leading functional signs are muscle strength of the arms and vital capacity of the lungs. Additional criteria can be the morbidity during the staying in the camp, and in terms of the nutritional status analysis - the results of bio-impedance analysis. To assess the physical development at the beginning of the camp trial, the use of regional regression scales is informative that requires a corresponding explanation in the documents. In turn, the data from the baseline measurements should be used to build individual health measures during the staying in the camp.

The present paper reviews the guidelines that have been developed and approved according to the established procedure for gas chromatographic analysis of volatile compounds from different classes, as well as phthalates contained in test chamber air and aqueous extracts. These guidelines contain various techniques and procedures for isolating, concentrating, and separating the substances to be detected using capillary columns having a large diameter. The potentials of statistical and dynamic vapor-phase analyses of aqueous extracts and absorption apparatus water after air sampling, as well as liquid extraction that is used to determine phthalates are applied.

The paper presents the results of sanitary-and-chemical studies of samples of tissues treated with new-generation textile auxiliaries (TAs). The application of new-generation TAs containing the lower levels of formaldehyde (FA) is shown not to eliminate the problem of their safe use in making children's clothes. The safe values for exposure to FA have been estimated in relation to the real load of a garment. The toxic action of cutaneous versus intragastric FA has been evaluated in immature rats. The clothes FA level of 20 microg/g has been found to produce no toxic effect on a living organism.

In the article the problems of actual nutrition and state of Russian children health are considered. The carried out examinations of the vitaminous status have shown presence of a deficit of vitamins E, B1, B6, PP, and also calcium, phosphorus, iron lactate, zinc in daily ration of children. The inadequate organization of C-vitaminization of boiled food in children establishments, low supplying of learning schools by a hot food, insufficient use of products from suer milk, fish, juices, meat products, butter, vegetables, fruit, eggs in a nutrition of children is marked. In same of regions of Russia the inadequate nutrition organization of early age children is marked. The positive experience of areas (St.-Petersburg, Ul'yanovsk, Rostov, Smolensk, Kirov, Kurgan, Samara region, Republic Buryatiya) on organization of children and juveniles nutrition, development of the regional programs on a children's food industry evolution, on providing of early age children by food stuffs, on improvement of a schoolboys nutrition, on improvement a nutrition of children in children's preschool establishments is analyzed. The positive experience of nutrition organization of children on an example of the Ryazan and Arkhangel'sk regions surveyed. The actual information about a vitaminization, quality and safety of children's nutrition, ready dishes in the organized collectives on data of 1999 are given.
