title: Trends in blood pressure control in patients with type 2 diabetes: data from the Swedish National Diabetes Register (NDR).
abstract: We assessed blood pressure (BP) trends in patients with type 2 diabetes from a national diabetes register using three cross-sectional samples (aged 30?85 years) in 2005, 2007 and 2009, and in patients from 2005 followed individually until 2009. The prevalence of hypertension was 87% among all 180 369 patients in 2009, although lower in subgroups with ages 30?39, 40?49 and 50?59 years: 40%, 60% and 77%. In the three cross-sectional surveys, mean BP decreased (141/77?136/76 mmHg), uncontrolled BP? 140/90 mmHg decreased (58?46%), and antihypertensive drug treatment (AHT) increased (73?81%). Comparatively in 79 185 patients followed individually for 5 years, mean BP decreased (141/77?137/75 mmHg), uncontrolled BP ?140/90 mmHg decreased (58?47%) and AHT increased (73?82%). Independent predictors of BP decrease were BMI decrease (stronger) and increase in AHT. AHT occurred among 81% of all patients in 2009. In 57 645 patients on AHT followed individually, mean BP decreased (143/77?138/75 mmHg) and uncontrolled BP ?140/90 mmHg decreased (63?50%). Among 5164 patients with nephropathy on AHT followed individually, BP <130/80 mmHg increased (12?21%). In conclusion, BP control improved from 2005 to 2009, relative to BMI decrease and AHT increase, although still about half had BP ?140/90 mmHg.
