Objective: To study the correlation between glycaemic control and blood pressure control, in order to determine the factors associated with blood pressure control in diabetic patients.

Methodology: This was a descriptive cross-sectional study with an analytical aim over a period of 7 months. Patients were recruited on an outpatient basis, and all underwent ABPM, measurement of glycated haemoglobin and creatinine levels, and assessment of compliance with treatment.

Results: Our criteria enabled us to select 116 patients. Women predominated (69%). The mean age of the patients was 62 ± 7 years, with a peak between 60 and 70 years. The mean duration of hypertension was 12 years and that of diabetes 6 years. The most frequently associated cardiovascular risk factor was physical inactivity (71.5%), followed by age. 57.8% of patients had uncontrolled blood pressure at the practice, with systolic hypertension predominating (58.2%). MAPA found that 61.6% of patients were controlled, giving a white-coat hypertension rate of 47.8%. Glycaemic control was observed in 42.2% of cases, and 87% of patients had good renal function. Compliance with treatment was good in 53.4% of cases, and dual therapy was the most commonly used treatment modality (44.8%), followed by triple therapy. The factors associated with poor blood pressure control were glycaemic imbalance, lack of compliance and monotherapy. Combination therapy was associated with good blood pressure control.

Conclusion: The association of hypertension and type 2 diabetes is frequent. The risk of occurrence increases with age. ABPM is the best method of assessing blood pressure control. Optimising blood pressure control in hypertensive diabetics requires optimising glycaemic control.
