Key result
Adults with diabetes had a significantly higher prevalence of hypertension (54.6%) compared to non-diabetic adults (26.2%), alongside lower blood pressure control rates among treated subjects, particularly in newly diagnosed patients (25.2% vs 68.4%).

Korean adults with diabetes have a higher prevalence of hypertension but significantly lower rates of blood pressure control compared to the general population, highlighting a need for more intensive management.
Suboptimal BP control in diabetes signals care gaps; leaves open whether targeted interventions improve outcomes.
BACKGROUND: We investigated the prevalence, awareness, treatment, and control rate of hypertension in Korean adults with diabetes using nationally representative data. METHODS: Using data of 5,105 adults from the fifth Korea National Health and Nutrition Examination Survey in 2011 (4,389 nondiabetes mellitus [non-DM]), 242 newly diagnosed with DM (new-DM), and 474 previously diagnosed with DM (known-DM), we analyzed the prevalence of hypertension (mean systolic blood pressure ≥140 mm Hg, diastolic blood pressure ≥90 mm Hg, or use of antihypertensive medication) and control rate of hypertension (blood pressure [BP] <130/80 mm Hg). RESULTS: The prevalence of hypertension in diabetic adults was 54.6% (44.4% in new-DM and 62.6% in known-DM, P<0.0001 and P<0.0001, respectively) compared with non-DM adults (26.2%). Compared to non-DM, awareness (85.7%, P<0.001) and treatment (97.0%, P=0.020) rates were higher in known-DM, whereas no differences were found between new-DM and non-DM. Control rate among all hypertensive subjects was lower in new-DM (14.9%), compared to non-DM (35.1%, P<0.001) and known-DM (33.3%, P=0.004). Control rate among treated subjects was also lower in new-DM (25.2%), compared to non-DM (68.4%, P<0.0001) and known-DM (39.9%, P<0.0001). CONCLUSION: Higher prevalence and low control rate of hypertension in adults with diabetes suggest that stringent efforts are needed to control BP in patients with diabetes, particularly in newly diagnosed diabetic patients.

Ko et al. (2014) conducted a cross-sectional in Hypertension and Diabetes Mellitus (n=5,105). Diabetes mellitus vs. Non-diabetes mellitus was evaluated on Prevalence of hypertension (p=<0.0001). Adults with diabetes had a significantly higher prevalence of hypertension (54.6%) compared to non-diabetic adults (26.2%), alongside lower blood pressure control rates among treated subjects, particularly in newly diagnosed patients (25.2% vs 68.4%).
