PREVALENCIA DE SINDROME METABOLICO EN LA POBLACIÓN ADULTA CHILENA SEGÚN LA DEFINICIÓN DEL PROGRAMA NACIONAL DEL COLESTEROL DE LOS ESTADOS UNIDOS (ATPIII) Y LA FEDERACIÓN INTERNACIONAL DE DIABETES (IDF): HALLAZGOS DE LA PRIMERA ENCUESTA NACIONAL DE SALUD
Resumen
Purpose: There are several criteria for MS definition. This study explores their application in the Chilean general adult population as a contribution to the study and refinement of diagnostic criteria in Chile.
Materials and Methods: We analysed data from a random sub sample of 1.833 adults 17 years and older surveyed during the First Chilean Nacional Health Survey conducted in 2003. Prevalences were estimated using the NCEP ATPIII 2004 and the IDF 2005 criteria. We analyzed the distribution of MS according to age, gender, educational level, geographic area, obesity and sedentary lifestyle.
Results: The prevalence of MS was 31.6% (28.5 – 34.9) and 36.8% (33.5 – 40.3) for ATPIII and IDF criteria respectively, 90% of adult population would be similarly classified with both criteria. Demographic and socioeconomic distribution was similar with both criteria. Prevalence of the MS components were: 46%, 22% and 52,6% for blood pressure, fasting glucose, and triglycerides respectively, common factors for both diagnostic criteria. High waist circumference prevalence was 29.7% and 59.4% for ATP III and IDF respectively. ATPIII gender, age and educational level adjusted prevalence odds were: 36,84 [21,37-63,5] and 2,09 [1,3-3,45] in the obese and sedentary population respectively.
Conclusions: ATP III and IDF MS criteria agreement in Chile is much higher than described elsewhere. The local distribution of metabolic syndrome components (triads) may differ between countries affecting criteria agreement and the overall prevalence in different populations. Waist circumference cut-offs suggested by IDF criteria seem to overestimate risk in our country and deserve local adaptation. High MS prevalence in Chile and its risk factors require urgent preventive measures and public health policies.
