Abstract

Objective: Metabolic syndrome (MetS) has become a worldwide epidemy as the result of a high prevalence of obesity and a sedentary lifestyle. This study was aimed to determine the predictive capacity of some anthropometric indexes on the metabolic syndrome MetS.

Methods: A cross-sectional study was carried out in 636 workers with an overall prevalence of MetS of 14.3%. Receiver Operating Characteristic curves have been carried out to determine the cut-off values. Diagnostic accuracy was determined from the sensitivity and specificity, predictive values, validity index, and Youden index.

Results: Waist-to-Height Ratio (WHtR) and Body Round Index (BRI) were the variables with the highest area under the curve (AUC) both with 0.89 CI 95% (0.858-0.927), followed by Waist Circumference with 0.87 CI 95% (0.83-0.909). The most outstanding cut-off values were: WtHR (0.54), with a sensitivity of 90.1% and a specificity of 76.1% and BRI (4.15) achieved a sensitivity and specificity of 90.1% and 76.1%, respectively.

Conclusions: WHtR and BRI are the anthropometric indicators that best discriminate the incidence and prevalence of MetS on the working population. In addition, they show a significant discriminatory capability of abdominal obesity.

Objetivo: El síndrome metabólico (SMet) se ha convertido en una epidemia a nivel mundial, como resultado de una alta prevalencia de obesidad y de un estilo de vida sedentario. El objetivo de este trabajo fue determinar la capacidad predictiva de los índices antropométricos sobre el SMet.

Metodos: Se realizó un estudio transversal en una muestra de 636 trabajadores, con una prevalencia global de SMet del 14,3%. Se realizaron Curvas Operador-Receptor para determinar los valores de corte. La precisión diagnóstica se determinó a partir de la sensibilidad y especificidad, los valores predictivos, el índice de validez y el índice de Youden.

Resultados: Las variables con mayor área bajo la curva (ABC) fueron el índice cintura-talla (ICT) y el índice de redondez del cuerpo (BRI) con 0,89 (IC 95% 0,858-0,927), seguidos de la circunferencia de cintura (CC) con 0,87 (IC 95% 0,83-0,909). Los valores de corte fueron: ICT=0,54, con una sensibilidad del 90,1% y una especificidad del 76,1%; BRI=4,15, con una sensibilidad y especificidad del 90,1% y 76,1%, respectivamente.

Conclusiones: El ICT y el BRI son los indicadores antropométricos que mejor discriminan la incidencia y prevalencia de SMet en población adulta laboral. Además, muestran una importante capacidad discriminatoria de obesidad abdominal.
