The purpose — to create a model for predicting the effectiveness of rehabilitation of obese children based on the consideration of risk factors. Material and methods. The study involved 250 children of 7–14 years old with obesity of 1–3 degrees, who received rehabilitation during 2 months in a children’s polyclinic. Before interventions, the children were assessed for anamnestic data, clinical status, dietary and physical activity stereotypes. The assessment of the rehabilitation effectiveness was carried out based on the clinical, functional and emotional status of the child and the calculation of the effectiveness of rehabilitation coefficient (ERC). A comparative analysis of the prevalence of risk factors in 2 groups of children was carried out, depending on the ERC: positive or negative. Statistical analysis was performed using the Kruskalm — Wallis and Kendall Tau methods, the risk and odds ratios were estimated, the ROC analysis procedure was performed. Statistical significance was p < 0,05. Results. The factors influencing the rehabilitation effectiveness were as follows: obesity in first-line relatives; the body fat and body mass indices, abdominal obesity, thyroid enlargement, muscle strength endurance, systolic blood pressure, self-esteem of health, excess food intake, frequency of a weekly milk consumption, frequency of drinking water during the day, frequency of shopping, sleep regularity, and daily exercise. The model for predicting the rehabilitation effectiveness was created based on one-step accounting of risk factors, the predictive power of was 91%. Conclusion. The оne-time consideration of risk factors allows identifying children with a positive and negative prognosis of rehabilitation.Children with a positive prognosis were directed to a polyclinic for rehabilitation, and among children with a negative prognosis, the reasons for the alleged failure were determined (secondary nature of obesity, insufficient physical activity of the offered programs, etc.).
