[Factors associated to glycaemic control in patients with type 2 diabetes]

Evaluate the factors influencing blood glucose control of type 2 diabetic patients attended at a tertiary health care center.

A retrospective study by review of medical records of patients who attended the Diabetes Clinic at the University of Caxias do Sul was carried out. Patients were evaluated for glycaemic and metabolic control and divided according to glycated hemoglobin at the beginning and end of the period in question, in compensated and not compensated. The factors associated with glycaemic control were analyzed.

Seventy three patients were included in the analysis. On the average, improvement of parameters related to glycaemic, pressure and lipid control during the average of 20 months of treatment was observed. In the beginning of the follow-up period, 25% of patients had glycated hemoglobin < 7%, 22.7% had LDL cholesterol < 100mg/dL, 8.7% had systolic blood pressure < 130 mmHg and diastolic < 80 mmHg and no patients had all parameters meeting the recommended goals. At the last visit the percentages were, 42.3%, 37.5%, 30.2% and 9.6% respectively. In the multivariate analysis, younger age, higher levels of LDL cholesterol and insulin use were associated with poor blood glucose control.

A small part of the sample simultaneously achieved the goals for blood glucose, lipids and blood pressure control. Some factors, such as age and gender can be determinants to achieve control of diabetes. Greater efforts are still needed to achieve the goals for treatment in type 2 diabetic patients.
