Resumen

Introducción: El objetivo del presente trabajo fue determinar la relación entre grasa corporal y Síndrome Metabólico (SM), utilizando curvas ROC, en adultos de una localidad del caribe colombiano.

Material y Métodos: Estudio transversal con 552 adultos de 20 a 64 años, con información completa de perfil lipídico, glicemia y mediciones antropométricas: peso, talla, presión arterial, perímetro de cintura y pliegues cutáneos. Se calculó porcentaje de grasa corporal mediante ecuaciones de Siri, Brozeck y Lean y se determinó la presencia de SM mediante 4 consensos: AHA, ATP III, IDF y Armonizado. Para comparar los promedios de grasa corporal según estos se usó T de Student y/o U de Mann Whitney. Se utilizó análisis de curvas ROC para determinar puntos de corte de la grasa corporal para determinar el SM.

Resultados: Las medias de grasa corporal fueron mayores en sujetos con SM independientemente del método utilizado (p<0,05). Las áreas bajo curva ROC oscilaron entre 63% y 76,9%, con sensibilidades entre 50% y 85%, y especificidades entre 51% y 78%. Mediante Lean-cintura y el consenso de AHA se obtuvo el valor más alto del área bajo la curva (0,77; punto de corte: 37,1; sensibilidad: 60,8; especificidad: 78,8%) y utilizando Siri y el consenso Armonizado se obtuvo el valor más bajo (0,63; punto de corte: 28,5; sensibilidad: 80%; especificidad: 42,5%).

Conclusiones: El análisis de curvas ROC permite identificar la relación entre grasa corporal y síndrome metabólico, y podría emplearse como tamizaje, teniendo en cuenta que los valores de sensibilidad y especificidad dependen de las mediciones antropométricas y las ecuaciones empleadas.
