Effectiveness of Comprehensive Lifestyle Correction with a Personalized Nutrition, Physical Activity, and Psychological Support Program in Children with Overweight and Obesity (Literature Review, Clinical Cases Description)

Introduction. Childhood overweight and obesity pose significant public health challenges, strongly associated with metabolic disorders such as insulin resistance, dyslipidemia, and chronic inflammation. Comprehensive interventions addressing lifestyle, including diet, physical activity, and psychological support, have shown promise in mitigating these conditions. The aim of the study. To review contemporary literature and analyze clinical cases to evaluate the effectiveness of a comprehensive lifestyle correction program for children with obesity. Materials and methods. The study includes an analysis of modern scientific literature and clinical cases from a specialized rehabilitation center. Key metrics such as body composition, metabolic markers, and lifestyle changes were assessed before and six months after the intervention. Results. The program led to a 7.0-10.0 % reduction in body weight, improved BMI, and normalized lipid profiles. Vitamin D levels increased, inflammation decreased, and physical activity levels rose from 5.0 % to 15.0 % of daily time. Sleep quality also improved. Conclusions. The personalized multidisciplinary approach effectively reduced weight and improved metabolic health indicators in children with obesity. The results underscore the importance of early, tailored interventions involving families and multidisciplinary teams to promote sustainable lifestyle changes. Expanding such programs could significantly reduce the long-term risks associated with pediatric obesity.
