To evaluate the value of body mass index (BMI) as predictor of waist circumference of cardiovascular risk (CRWC) and diagnostic of metabolic syndrome (MSWC) in patients with type 2 diabetes mellitus (DM 2), we assessed BMI and WC in 753 patients with DM 2 (472 women) with 23 ± 8 years. The participants had been divided in groups in accordance with the presence or absence of ACCR or ACMS. The best BMI cut-off to predict such disturbances was evaluated in women and men. In females, BMI > 25.0 kg/m² was the best predictor of CRWC. Area under ROC curve and IC 95% were 0.7202 (0.6753 - 0.7652) for CRWC and of [0.8318 (0.7928 - 0.8708)] for MSWC. In males, IMC > 25.0 kg/m² was better predictor for CRWC presence [0.8527 (0.8098 - 0.8955)], while BMI > 30.0 kg/m² for MSWC [0.9071 (0.8708 - 0.9433)]. We conclude that BMI can be a simple way to evaluate metabolic syndrome and cardiovascular risk where there were not material and prepared professionals for the WC evaluation. We need prospective studies to evaluate if it is necessary to change the BMI cut-off adopted as indicative of these disturbances in the diabetic population.
