[Prevalence of metabolic syndrome and consistency in its diagnosis in type 2 diabetic patients in Spain]. / Prevalencia del síndrome metabólico y grado de concordancia en su diagnóstico en pacientes con diabetes mellitus tipo 2 en España.

OBJECTIVE: To determine the prevalence of metabolic syndrome, the degree of consistency among World Health Organization (WHO), The Third Report National Cholesterol Education Program (NCEP-ATP III) and the International Diabetes Federation (IDF) diagnostic criteria and the relationship with cardiovascular risk in a Spanish population of patients with type 2 diabetes. MATERIAL AND METHODS: This descriptive, epidemiologic, multicenter and cross-sectional study included 1259 patients with type 2 diabetes. The primary variable was diagnosis of metabolic syndrome according to WHO, NCEP-ATP III and IDF criteria. RESULTS: The prevalence of metabolic syndrome was 71.5% (WHO), 78.2% (NCEP-ATP III), and 89.5% (IDF). The prevalence of metabolic syndrome was higher in sedentary diabetic patients (WHO=79.3%, NCEP-ATP III=86.2%, and IDF=93.9) than in those who exercised moderately (WHO=61.4%, NCEP-ATP III=73.2%, and IDF=85.5%, [p<0.001]). The percentage of patients with metabolic syndrome and moderate/high cardiovascular risk was 38.9% (WHO), 33.6% (NCEP-ATP III), and 30.1%, (IDF). Consistency among WHO, NCEP-ATP III and IDF criteria was low. Only comparison of WHO vs NCEP-ATP III criteria was acceptable (k=0.52 [0.46-0.58]). CONCLUSIONS: The prevalence of metabolic syndrome in patients with type 2 diabetes in Spain is high, even when the low consistency among WHO, NCEP-ATP III and IDF criteria is considered. A standard definition of metabolic syndrome, according to routine clinical practice, is needed. Cardiovascular risk is greater when OMS and NCEP-ATP III criteria are used for the diagnosis of metabolic syndrome compared with IDF criteria.

Prevalencia del síndrome metabólico y grado de concordancia en su diagnóstico en pacientes con diabetes mellitus tipo 2 en España / Prevalence of metabolic syndrome and consistency in its diagnosis in type 2 diabetic patients in Spain

Objetivo Determinar la prevalencia, grado de concordancia y relación con el riesgo cardiovascular del síndrome metabólico según los criterios de la Organización Mundial de la Salud (OMS), el The Third Report National Cholesterol Education Program (NCEP-ATP III) y la International Diabetes Federation (IDF) en una población española de pacientes con diabetes tipo 2.Material y métodos Estudio descriptivo, epidemiológico, multicéntrico y transversal que incluyó 1.259 adultos con diabetes tipo 2. La variable principal fue el diagnóstico de síndrome metabólico, según los criterios de la OMS, el NCEP-ATP III y la IDF. Resultados La prevalencia de síndrome metabólico fue 71,5% (OMS), 78,2% (NCEP-ATP III) y 89,5% (IDF). La prevalencia de síndrome metabólico es mayor en pacientes diabéticos sedentarios (OMS=79,3%; NCEP-ATP III=86,2%; IDF=93,9%) que en aquellos que realizan una actividad física moderada, (OMS=61,4%; NCEP-ATP III=73,2%; IDF=85,5%; [p<0,001]). El porcentaje de pacientes con síndrome metabólico y riesgo cardiovascular moderado/alto fue 38,9% (OMS), 33,6% (NCEP-ATP III) y 30,1% (IDF). El grado de concordancia entre los criterios diagnósticos fue bajo. Solo fue aceptable la comparación OMS/NCEP-ATP III (k=0,52 [0,46–0,58]).Conclusiones La prevalencia de síndrome metabólico en pacientes diabéticos tipo 2 en España es elevada, siendo bajo el grado de concordancia entre los distintos criterios diagnósticos. Es necesario establecer una definición estándar de síndrome metabólico de acuerdo con la práctica clínica habitual. El riesgo cardiovascular es superior cuando se utilizan los criterios OMS y NCEP-ATP III para el diagnóstico del síndrome metabólico en comparación con los de la IDF (AU)
