AIMS: We investigated the long-term changes in the prevalence and the control rate of hypertension among Korean adults diagnosed with diabetes. METHODS: Using data from the Korean National Health and Nutrition Examination Survey (1998-2008), including 1384 adults diagnosed with diabetes, we analyzed changes in the prevalence of hypertension (mean SBP ≥ 140 mmHg, DBP ≥ 90 mmHg, or use of antihypertensive medication) and the control rate of hypertension (BP < 130/80 mmHg). RESULTS: The prevalence of hypertension in diabetic adults was 50.9% in 1998 and 51.7% in 2008 (P = 0.563). The mean blood pressure decreased from 138.1 ± 1.1/80.0 ± 0.6 mmHg to 124.7 ± 0.8/76.0 ± 0.5 mmHg (P < 0.001); awareness (37.4 to 85.2%, P < 0.001), treatment (37.4 to 81.8%, P < 0.001), and the control rate (20.1 to 34.7%, P = 0.001) steadily increased. The prevalence of hypertension increased significantly more in the obese group compared with the non-obese group (53.3% vs. 49.0% in 1998, P = 0.784; 64.3% vs. 42.0% in 2008, P < 0.0001, respectively, P for trend = 0.0001). CONCLUSIONS: Although the rates of hypertension treatment have significantly improved, the control rate remains inadequate, and intensive intervention is urgently needed.
