    Objective: To evaluate the discriminative ability to predict diabetes with anthropometric and biochemical indicators and medical history. Methods: The sampling carried out was census and the sample consisted of 104 workers. A longitudinal study was carried out to evaluate the discriminative ability to predict diabetes with the anthropometric, biochemical, and antecedent indicators, using two models, the analysis of the ROC curves and binary logistic regression. Results: By analyzing the ROC curves, the abdominal circumference obtained greater predictive discriminative power (AUC = 0.747; p <0.001; CI: 0.624-0.870), compared to glycemia (AUC=0.749; p <0.001; CI: 0.645-0.852) and the waist-height index (AUC=0.737; p=0.001; CI: 0.638-0.836). Personal medical history is included in the logistic regression equation P(Y=1)=(1+e0,693+1,897APP)-1 to predict the risk of developing diabetes in the future. Conclusions: The abdominal circumference obtained the highest discriminative power, followed by the pathological history.Objetivo: Evaluar la capacidad discriminativa de predicci贸n de diabetes con indicadores antropom茅tricos, bioqu铆micos y antecedentes. M茅todos: Se utilizaron dos modelos, el an谩lisis de las curvas ROC y regresi贸n log铆stica binaria. Resultados: Mediante el an谩lisis de las curvas ROC, el per铆metro abdominal obtuvo mayor poder discriminativo de predicci贸n (AUC=0,747; p<0,001; IC: 0,624-0,870), en comparaci贸n a la glicemia (AUC=0,749; p<0,001; IC: 0,645-0,852) y el 铆ndice de cintura-talla (AUC=0,737; p=0,001; IC: 0,638-0,836). Los antecedentes patol贸gicos personales se incluyen en la ecuaci贸n de regresi贸n log铆stica P(Y=1) = (1+e0,693+1,897APP)-1 para predecir el riesgo de tener diabetes en el futuro. Conclusiones: El per铆metro abdominal obtuvo mayor poder discriminativo, seguido de los antecedentes patol贸gicos personales. &nbsp
