The IAEA funded project "Applying Nuclear Techniques to Design and Evaluate Interventions to Prevent and Control Obesity in Adolescents in South-Eastern Europe" ended successfully. The obectives focused on the prevention and control of non-communicable diseases through improvements in techniques for measuring body composition and physical activity to address adolescent obesity. Our results are summarized in: "New bioelectrical impedance analysis equations for children and adolescents based on the deuterium dilution technique" 10.1016/j.clnesp.2021.05.001 (OA article)
