Objectives : The aim is to analyze the relationship between the index waist-hip and the glucemia values in the population with disorders related to the homeostasis of the glucosa. Also, if this index is related with the appearance of macrovascular complications. Patients And Method : Observational analytic longitudinal study. Location: Healht Area of Málaga, with patients belonging to two Basic Health Areas. By means of systematized randomized criteria, a sample of 180 patients is selected (60 intolerant to the glucose, 60 diabetic type 2, and 60 controls, according to the postulates of the World Health Organization). Based on a multiparametric record of own elaboration we proceed to the collection of clinical data and antrhopometric parameters and blood pressure values. In the second part of the process the patients were carried out an analytic extraction and an electrocardiogram of 12 derivations. For the statistical prosecution the program JMP of the SAS Institute was used. Results : Macrovascular complication was detected in 35% of the patients with intolerance to glucose, in 40% of the patients diabetic type 2 and in 15% of the controls. The values means of the basal glucemia in the intolerant ones to glucose were of 119.23 ± 9.46 mg/dl, in the diabetic type 2, of 174.63 ± 54.53 mg/dl and in the controls of 91.5 ± 7.34 mg/dl. The medium value of the index waist-hip in the intolerant ones to the glucose was of 0.97 ± 0.05, in the diabetic type 2 the same figure, and in the controls, 0.95 ± 0.07. Conclusions : The central obesity is correlated positively with the disorders of homeostasis of the glucose and with the appearance of macrovascular complications.
