Objective : To determine the prevalence of hypertension, patterns of antihypertensive treatment and level of
blood pressure control in adult Thai type 2 diabetic patients who attended diabetes clinics in university and
tertiary-care hospitals.
Materials and Methods : A cross-sectional, multi-center, hospital-based diabetes registry of 8,884 adults 18
years old and older was carried out from diabetes clinics of 11 tertiary centers. Demographic data, including
use of antihypertensive drugs and blood samples were collected and analyzed for prevalence, associated
factors, patterns of antihypertensive therapy and level of blood pressure control.
Results : The prevalence of hypertension in adult Thai type 2 diabetic patients was 78.4 (6,965)%. Antihy-
pertensive drugs were prescribed in 84.4 (5,878)% of all hypertensive patients. The achievement of blood pressure
control (less than 130/80 mmHg) was 13.85%. The percentage of patients receiving 1, 2, 3, 4, and 5 drugs were
45 (2,645)%, 33.4 (1,963)%, 16.8 (987)%, 4.4 (259)%, and 0.4 (24)% respectively. Angiotensin-converting
enzyme inhibitors were the most commonly prescribed antihypertensive agents (54.6%), followed by diuretics
(43.8%), and calcium channel blockers (34.6%).
Conclusion : Blood pressure control in hypertensive adults with type 2 diabetes was suboptimal. Strategies to
improve awareness and adequacy of blood pressure control in these subjects should be seriously considered.
