The objectives of this study are to provide a description of the demographic, anthropometric characteristics and metabolic abnormalities in children with early-onset (< 10 years) and of very-early-onset obesity (< 5 years). We also evaluate the diagnostic ability using the definition of metabolic syndrome (MS) according to different criteria. Methods: It is a retrospective, case-control, cross-sectional, multicenter study. A total of 10 Pediatric Endocrinology Units in different Spanish hospitals were involved. A group of 469 children with early-onset obesity and another group of 30 children with very early-onset obesity were studied. The control group consisted of 224 healthy children younger than 10 years. Anthropometric and analytical determination of carbohydrates metabolism parameters and the lipid profile were performed. Results: The presence of metabolic alterations associated with obesity in children and adolescents in Spain is remarkable, either on their own, or encompassed within the definition of MS. This prevalence increases substantially when considering the peripheral resistance to insulin action as a diagnostic criterion. It also shows how children who could not be diagnosed with MS according to the definition provided by the International Diabetes Federation (IDF) due to age below 10 years, these alterations are already present in a remarkable percentage. In fact, metabolic abnormalities are already present in the very-early-onset obese children (<5 years). Conclusion: In Spanish children there are metabolic alterations associated with obesity in the infant-juvenile stages alone or encompassed within the definition of MS, and are already present at earlier ages.
