The contribution is part of the ‘Diet and Nutrition’ thematic area and aims to involve participants in the event with activities concerning the prevention of childhood obesity and related health issues. A multidisciplinary round table on the topic will be organised (with the presence of a paediatric endocrinologist, a neonatologist, a doctor of exercise science, a psychologist and a dietician) and a session of playful-motor activities to involve children and parents; a questionnaire on the eating habits and lifestyle of children and families will also be proposed, as well as information material to explore the above-mentioned topics.
