The research area: pediatrics

Purpose of the research:Evaluation of the incidence, types of obesity, anthropometric features in overweight/obese children during puberty; highlighting obesity risk groups and assessing the impact of obesity/overweight on the quality of life and personality.

Study objectives: 1) Estimating the prevalence of overweight/obesity and anthropometric particularities in children. 2) Determination of total adipose tissue level with elaboration of regional centile tables for children of 10-16 years 3) Highlighting the risk groups of obesity/overweight in children during puberty. 4) Assessing the effect of excess body weight/obesity on the metabolism of fats and carbohydrates. 5) Studying the impact of obesity/overweight on the quality of life and psychoemotional status.

The novelty and the scientific originality.For the first time in the Republic of Moldova the incidence of excess body mass and obesity was assessed in 10-16 year olds with the determination of anthropometric particularities. The neck and arm circumference values were used as criteria for the assessment of weight excess in children. The total fat mass values were evaluated by the electric bioimpedance method with the development of the children's centile tables. There were highlighted the risk factors that lead to pathology at puberty. The psycho-emotional status and the impact of obesity on children's lives was appreciated.

The scientific problem solvedin the thesis is to highlight the risk factors of the overweight in children during the puberty period with the elaboration of the score for the identification of the risk groups. Early application of prophylactic measures to these children will help reduce the number of children with overweight. Determination of body composition by the bioelectric impedance method with the elaboration of regional centile tables for the percentage of total adipose tissue allows a more accurate evaluation of the nutritional status in children and the estimation of the metabolic complications of the overweight.

The theoretical significance and the applicable value of this study. Elaborating reference values for neck and arm circumferences to identify overweight children will simplify the recognition of overweight children. Determining percentages of total body fat allows highlighting of children with this increased index, which still fall within the normal BMI. The careful study of the risk factors for the overweight allows for the risk groups to be highlighted for the purpose of applying the early prophylactic measures. The lower quality of life in overweight children emphasizes the need for a complex, interdisciplinary assessment of this pathology with psychological assistance in addressing children.

Implementation of scientific results. The results of the study are applied in the educational-didactic process in the Department of Pediatrics, in the Gastroenterological department of the Scientific Research Institute of Mother and Child Health Care
