**1. Introduction**

The World Health Organization (WHO) estimated that nearly one third of the population of the planet is infected with *Mycobacterium tuberculosis* (MBT), as 8–10 million new active cases of pulmonary tuberculosis (TB) are registered annually [1]. The general epidemic situation on tuberculosis for the last 10–15 years has negatively affected the incidence of tuberculosis in children. First, the contact with adults suffering from tuberculosis, especially with bacterial isolation, causes new cases of infection of MBT in children. At the same time, social and economic reforms have given to considerable decrease in number of healthy children in structure of younger generation – from 4 to 10% [2]. In modern social and economic conditions, a relevant task is to create optimum conditions for healthy motherhood, providing the birth and development of a healthy child [3, 4]. Becomes obvious that negative processes of formation of health of younger generation are connected with growth of socially caused diseases at children and pregnant women, in particular tuberculosis [5]. The development of health care has put in the forefront the need for assessing the health of a child taking into account many, first of all social,

factors [6]. During an economic crisis, the leading value, from the point of view of maintaining health, is on the quality of life of the child and his or her family members [7]. In recent years, the directions of studying the quality of life of children in clinical and in social pediatrics have extended [8]. WHO has suggested considering quality of life (life quality) as an optimum condition of perception by certain people and the population in general how their requirements as opportunities for achievement of well-being and self-realization are given are satisfied. Tuberculosis, influencing the physical state and psychology of behavior of an individual, changes his or her place and role in society [1]. In this regard, one of the new criteria for the evaluation of efficiency of delivery of health care is the quality of life. Today, it sounds as follows: the quality of life is a perception by an individual of his or her situation in life in the context of culture and the system of values in which the individual lives, and in connection with the purposes, expectations, standards, and the interests of this individual [9]. As quite often health depends on the level of availability of medical care, WHO considers the general availability of medical care of acceptable quality to children and adolescents mandatory at the present stage of development of society. Traditional criteria do not cover all aspects of a tuberculosis infection and do not allow estimating a condition of the sick child comprehensively. During the analysis of the quality of life parameters, there is an opportunity to define the influence of a disease on physical, psychological, and social aspects of functioning of an organism [10]. The use of this simple and reliable method will allow to improve the quality of medical care at different stages of treatment to children with chronic diseases, in particular, TB patients.
