[Body adiposity and its influence on clinical and metabolic parameters of patients with type 1 diabetes]

We evaluated the influence of body adiposity (BA), which was measured by bioelectrical impedance, body mass index (BMI) and waist circumference (WC), in clinical and laboratorial parameters of 64 patients with type 1 diabetes (DM1), 33 females, matched for diabetes duration. Women had greater BA than men. Fourteen patients were overweight. In the whole group, we found correlations between BA and BMI (r= 0.50; p= 0.001), BA and WC (r= 0.30; p= 0.001) and BA and fasting glucose (r= 0.24; p= 0.048). There were 11 patients with abnormal BA; among them, there were 6 with overweight and abnormal WC. In those patients with abnormal BA, we found higher HbA1c, respectively [(9.8 +/- 2.4) vs. (8.1 +/- 1.5%); p= 0.03], WC [(82.9 +/- 11.4) vs. (72.9 +/- 8.3 cm); p = 0.01] and BMI [(26.1 +/- 2.7) vs. (22.1 +/- 2.5 Kg/m2); p= 0.0001]. We conclude that some DM1 patients can have some characteristics of the metabolic syndrome and the influence of these findings on clinical and laboratory control and on the cardiovascular risk must be analysed in prospectives studies.
