ABSTRACT
Resumen Introducción: El síndrome metabólico (SM) es un problema de salud pública, el cual no cuenta con estrategias adecuadas de prevención, diagnóstico y tratamiento para población infantil. Los criterios existentes son controversiales y no son aplicables en los niños. Asimismo, varían según autores y comités de expertos; lo que podría tener importantes consecuencias en el diagnóstico de SM, impactando el tratamiento oportuno y el pronóstico del individuo. Objetivo: Validar criterios (NCEP-ATPIII; Cook, Ford y Duncan, et al; Ferranti, et al; Cruz, et al; e IDF1) para el diagnóstico de SM en niños mexicanos. Metodología: Estudio transversal de 2599 niños entre 6 y 16 años, residentes de la Ciudad de México. Se consideró SM con tres o más de los cinco componentes en los distintos criterios; y dos o más componentes con la presencia de obesidad central para IDF. Se consideró como Gold Standard la combinación de los cinco criterios diagnósticos. Para identificar el mejor valor predictivo se calculó sensibilidad, especificidad, valor predictivo positivo (VPP), valor predictivo negativo (VPN) y razón de verosimilitud. Resultados: Se observó una mayor proporción de individuos diagnosticados con SM con el criterio de Ferranti, et al. en comparación con los demás criterios evaluados. Nuestra propuesta ad hoc presentó una alta sensibilidad (0,89) y especificidad (0,90) frente al Gold Standard aplicado. Conclusión: El criterio propuesto por nosotros contiene una elección de componentes sencillos y de bajo costo, que facilitará su aplicación, permitiendo la unificación en el diagnóstico, tratamiento y pronóstico poblacional, reduciendo los índices de morbimortalidad en mexicanos.
Abstract Introduction: Metabolic syndrome (MS) is a public health problem without appropriate strategies for prevention, diagnosis and treatment in children. Existing criteria are controversial and not applicable for pediatric population, with variations according to different authors and expert committees, which could have important consequences in MS diagnosis, treatment and prognosis. Objective: To validate different definitions (NCEP-ATPIII; Cook, Ford and Duncan, et al; Ferranti, et al; Cruz, et al; and IDF1) for metabolic syndrome diagnosis in Mexican children. Methodology: Cross-sectional study of 2599 children aged between 6 and 16 years, residents of Mexico City. MS was defined as the presence of three or more of the five components in the different criteria; and two or more components with the presence of central obesity for IDF. The Gold Standard was considered as the combination of the five diagnostic criteria. To identify the best predictive value, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and likelihood ratio were calculated. Results: A greater proportion of individuals diagnosed with the Ferranti, et al criterion was observed in comparison with the other criteria evaluated. We proposed an ad hoc criteria which showed a high sensitivity (0,89) and specificity (0,90) compared to the Gold Standard applied. Conclusion: Our diagnostic criteria contains a choice of simple and low-cost components that will facilitate its application in health institutions and will unify-diagnostic criteria, treatment, and prognosis, reducing morbidity and mortality rates in Mexican population.

OBJECTIVE: To present a monographic review of different definitions for the diagnosis of metabolic syndrome (MS) in children. DATA COLLECTION: Consult and literature review. SELECTION OF STUDIES: We included in the review articles in relation to the different definitions used for the diagnosis of MS worldwide. RESULTS: There are significant differences in both criteria for MS in children and adults. Some of these definitions include hyperglycemia after an oral glucose load, while others only consider fasting glycemia; other differences include obesity criteria with different cutoffs for waist circumference (CC) or body mass index (BMI); different values ââfor dyslipidemia criteria for triglycerides (TGC) and high density lipoprotein cholesterol (HDL-C); and different cutoffs for defining high blood pressure (HTA). The approach to each definition differs from the importance that each component or risk factor assumes. CONCLUSION: It is important to establish an appropriate definition for the diagnosis of MS in children, under the great controversies reported by authors and expert committees. This variability in the prevalence of MS populations from the use of different criteria makes it difficult to know the prevalence of MS for certain. Having a national consensus would serve to propose appropriate public health actions that could allow us to reduce the rates of morbidity and high costs for health institutions.
