[Blood pressure control in a population of hypertensive diabetic patients treated in primary care: PRESCAP-Diabetes Study 2010]

Abstract

Objectives: To determine the level of blood pressure (BP) control in hypertensive diabetic patients treated in primary care and to determine the factors associated with poor control.

Material and methods: A cross-sectional, multicentre study that enrolled hypertensive diabetics recruited by consecutive sampling by family doctors in Spain in June 2010. A mean BP of less than 140/90mmHg was considered as good control of arterial hypertension. The percentages of patients with<130/80mmHg PA, 140/80mmHg, and 140/85mmHg, respectively, were also determined. Sociodemographic, clinical, cardiovascular risk factors, and pharmacological treatments were recorded.

Results: A total of 3,993 patients were enrolled (50.1% female) with a mean age (standard deviation) of 68.2 (10.2) years, of whom 73.9% received combination therapy. The figures showed good control of both blood pressure values (<140/90mmHg) in 56.4% (95% CI: 54.3 to 58.4) of the cases, with 58.5% (95% CI: 57.0-60.0) only in systolic BP, and 84.6% (95% CI, 83.2 to 85.8) only in diastolic BP. The variables with strongest association with poor control were the presence of albuminuria, elevated total cholesterol, physical inactivity, and not taking the medication on the day of the interview.

Conclusions: The PRESCAP-Diabetes 2010 study results indicate that 43.6% of diabetics with hypertension seen in primary care have a poorly controlled BP, in particular, systolic BP.
