Persistence of metabolic syndrome in children and adolescents are overweight according to two diagnostic criteria: a longitudinal study

Resumen

Objective: To investigate the persistence of the metabolic syndrome (MS) in children and adolescents are overweight according to the diagnostic criteria of the World Health Organization (WHO) and National Cholesterol Education Panel Adult Treatment Program- III (NCEP / ATP III). Methods: A longitudinal study was conducted at the Center for Childhood Obesity between April/2009 and April/2012, involving 133 children and adolescents are overweight. The evaluation was made at first and after 24 months of follow up, anthropometry being performed, then the nutritional classification and diagnosis of MS which was subsequently divided into three groups: negative, intermittent and and persistent MS. Descriptive and agreement between the two criteria and also between groups analysis was performed using the Kappa index, using SPSS version 17.0 (95% CI). Results: Among those evaluated, the majority were female (60.9%), and adolescent with severe obesity. Among the components of metabolic syndrome, fasting glucose, blood pressure levels and insulin resistance were reduced in the period. There was no significant correlation between the diagnostic criteria, although it has seen significant coincidence in the group with persistent metabolic syndrome (p = 0.002). Conclusion: A significant similarity between the criteria of WHO and NCEP/ATPIII only in the group with persistent SM, demonstrating sensitivity of the tests, but the use of more specific markers for this age group it is necessary to identify the early SM.
