Sarkuland Kenkiyak settlements are located in the Aktobe province, at18-20 km from the oil and gas producing field "Zhanazhol", in the northwest region of the Republic of Kazakhstan. To evaluate the exposure of the adult male and female population living in Sarkul and Kenkiyak settlements, a single medical study was conducted. The nonparametric method of the Spearman correlation analysis was performed between the mean concentration of substances exceeding the Maximum Permissible Concentration and the classes of newly diagnosed diseases. Selection and analysis of air samples was carried out according to the developed research protocol; the qualitative-quantitative analysis was carried out on the Gas analyzer HANK-4 apparatus. Significant pollution of atmospheric air by carbon monoxide, benzapyrene, dust and phenol were identified in places. Correlation dependencies between these pollutants of air and the diseases of the population revealed as a result of medical examination are established, as a result of diseases of the circulatory system, ear and mastoid process, nervous system and digestive organs; between the concentration of carbon monoxide and diseases of the circulatory system, the digestive system, the genitourinary system and the musculoskeletal system; between nitric oxide and diseases of the digestive system and the circulatory system; between benzopyrene and diseases of the digestive system, the genitourinary system and the nervous system.

The article analyzes statistical data for the adult population of the oil and gas producing region at the Aktobe district over 2011-2015. Data on the incidence of malignant (reporting statistical forms No. 35 and No. 7) of the adult population of Mugalzhar, Temirsky district in the Aktobe region were studied in the process of the implementation of the research. In the work, there were used statistical and epidemiological methods. There was a decline in the primary incidence of malignant tumors (MT) in the adult population in Mugalzhar region (there is a gradual decrease from 2011 till 2014, in 2015 -the sharp decrease of the indices of the primary incidence) and Kobdinsky region (there is a decrease of the MT from 2013 and an increase in the rate of growth in Temirsky region (the incidence of MT decreases from 2011 till 2013, the trend of increasing primary indices is traced from 2013) during the period under review. Ranking of the MT with the first time established diagnosis among the adult population living in the Mugalzhar district showed the women’s breast cancer to held the first place, the second - the esophagus, the third place is the uterus. The elderly population of the Temir district is ranked first with MT of the esophagus, on the second - MT of tracheaetracheae, bronchus, lung, in third place - MT of the women’s breast. Among the adult population of the Kobda district, which is the control, the MT of the stomach is leading, after it the MT of tracheae, bronchus, lung, the MT esophagus is on the third place. The statistically significant direct, strong correlations between the annual average daily concentration of carbon monoxide, nitric oxide, hydrocarbon in the atmospheric air and the index of the MT incidence (body of uterus, uterine cervix, breast, mammary gland) at the adult population was revealed. In the Mugalzharsky and Kobdinsky districts the proportion of people living by 2015 more than 5 years from the date of diagnosis is higher than in the Temir district. In the Temir district, the detection rate among newly registered MT patients, in comparison with the Mugalzhar and Kobdinsky regions is high at the I-II stages, and at the IV stage.

BACKGROUND: The frequency of breakfast consumption as a determinant of fruit and vegetable intake among children and adolescents has been poorly investigated. AIM: In this article, we examine whether irregular food intake is associated with fruit and vegetable intake among children and adolescents. METHODS: We use a separate analysis, with special attention being paid to the potentially changing effects of gender and age. The methodology of health behavior in school-aged children is used. RESULTS: The obtained results show that irregular breakfast consumption among children and adolescents is associated with a low frequency of fruit and vegetable intake and that gender and age can play a decisive role. Various associations observed in different age and gender groups indicate the importance of a separate analysis of fruit and vegetable intake and types of food. CONCLUSION: The results emphasize the importance of encouraging regular food intake while trying to increase fruit and vegetable intake among children and adolescents.

BACKGROUND: This article focuses on the health risk assessment associated with air pollution for the population of the Temir district in the Aktobe region. The risk assessment of the effects of air pollution on public health revealed a tendency to deterioration in the health indicators of the children’s population. AIM: The research object was the population of the Temir district living near the oil and gas field Zhanazhol. METHODS: The work was carried out according to the risk assessment methodology described in the manual R 2.1.10-1920-04. The maximum non-carcinogenic risk due to exposure to chemicals in the air basin of residential areas was established for children from 0 to 6 years of age in the Temir district. RESULTS: A high risk of respiratory, blood, and cardiovascular diseases was observed. Sulfur dioxide, hydrogen sulfide, nitrogen, and carbon oxides contained in atmospheric air contribute to the risk of developing these diseases. The levels of carcinogenic risk to public health in the Temir district show that the maximum individual risk of oncological diseases is observed in the group of children. The risk of malignant neoplasms in adolescents is 1.2 times lower, in the male population – 1.4 times lower, on average, and in the female population – 1.3 times lower than in children. Public health risk analysis aims to select the best ways in a particular situation to eliminate or reduce risk associated with air pollution for the population. CONCLUSION: The methodology of a comprehensive health risk analysis is a promising and developing approach in the system of monitoring the quality of the human environment and assessing environmental hazards.

Objectives: The purpose of this article is to study and generalize, detect main tendencies in modern views on various aspects of the psychological health of adolescents in recent publications (taken into account the publication on multiple problems of adolescents’ health over the past decade: 2009-2019). Method: The literature search was conducted using Medline, TRIP Database and Cochrane Library to identify relevant medical studies over the past 10 years (2009-2019). The keywords search and title search and advanced search were applied in order to determine the articles and other forms of surveys on the general topic of adolescents’ psychological health. The articles were filtered for the TOP-30 concerning chronological principle and their actuality, novelty, citation level and deepness of the researchable aspect. Results: Multiple publications that focus on the psychological health of adolescents were detected. They concentrate on the principal factors that force pathological psychical behaviour among adolescents. E.g., the impact of family members' health and life-limiting conditions, unemployment and precarious employment, the negative impact of alcohol and the Internet, cognitive-behavioral therapy programs, the internalization of symptoms in depressive or anxious states, Internet-based therapy, responses to antidepressants, the Youth Version Short (EQ-i: YV-S) have been described. The chosen medical studies have been systemized in the form of a table and some of them were discussed more closely due to their importance and novelty. Conclusions: The study generalizes the most modern and innovatory views on aspects of the psychological health of adolescents in international publications taking into account synchronic and diachronic notions. The study may be used for close browsing of the current state of investigations in this scientific area as well as for further investigations in the forms of surveys and clinical experiments take notice of already detected and undetected yet problems.
