The aim: Of the work was to study and evaluate the risk factors and the level of primary medical care for children with overweight and obesity. Materials and methods: A sociological survey was conducted in main (413 persons) and control group (396 persons) and the copying from the history of the child’s development (f.112/a) of 280 obese children was conducted. Results: It was defined that on the development of excess weight in children and adolescents, biological and social and hygienic factors had a significant impact (η ≥ 3%; p<0,001) and that the level of primary medical care for obese children (proved diagnosis of obesity in the history of the child (f. №.112/а) had only 61,7±2,7% of patients) was insufficient. Conclusions: Identification of comprehensive priority activities for solving problem of children overweight and obesity based on the results of conducted research were done.

The aim of the work is medical and social substantiation and development the model of management by the quality of life of obese children. Materials and methods: Material processing was performed by using of mathematic-statistical methods: variance, correlation and regression analysis, mathematical prediction, modelling; the relative, average values and their errors were calculated as well as the predictive coefficients, and the odds ratios, which made it possible to obtain reliable data. Results: It was found that the real prevalence of obesity among children and adolescents in Kharkiv was significantly different from the official statistics in Kharkiv region (15,0 per 1,000 of infant population). The general level of excess weight in 2016 was 151,0±5,2‰. It was developed a technique for predicting the risk of excess body weight in children based on a heterogeneous sequential recognition procedure, which with 95% of probability can determine the patient’s belonging to a particular risk group. Conclusions: The model of management by the quality of life for obese children was developed. Offered model of management allows to eliminate the managed factors of development of this pathology, to conduct comprehensive monitoring of the state of children’s health, to eliminate certain shortcomings of the health care organization, in particular at the primary level, to raise the awareness of the population on methods of prevention, to apply innovative medical technologies, which in turn will help to improve the quality of life for obese children.

The aim of the work was to study and evaluate the quality of medical care provided to patients with myocardial infarction. Materials and methods: A sociological survey was conducted in 310 people with myocardial infarction and the copying of data from 318 statistical maps of patients who left the hospital. Results: It was defined that the majority of patients, 57.7 ± 2.8%, were not offered psychological rehabilitation, only 42.3 ± 2.8% were recommended the consultation of a psychologist; most of patients, 89.3±1.78%, were unaware of the possibility of self-monitoring of their health status after myocardial infarction and 10.7 ± 1.8% kept selfcontrol diaries; 88.4±1.9% of patients were under monitoring supervision, while 11.6 ± 1.9% were not under it. Conclusions: Identification of the quality of care makes it possible to optimize the system of providing health care for patients with myocardial infarction.
