Prevalence of hypertension in type 2 diabetes mellitus: impact of the tightening definition of high blood pressure and association with confounding risk factors

J Cardiometab Syndr. 2006 Spring;1(2):95-101. doi: 10.1111/j.1559-4564.2006.05513.x.


The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 7) has recommended a downward shift in target blood pressure to <130/80 mm Hg in diabetic patients, thus operatively setting a new threshold level for the definition of hypertension at 130/80 mm Hg. The authors performed a retrospective chart analysis of 2227 type 2 diabetes patients treated in one hospital-based and two community-based clinics in central Israel to determine the prevalence of hypertension as a function of three diagnostic threshold levels. The prevalence of hypertension in this cohort was 60.2%, 76.5%, and 85.8% at blood pressure thresholds of 140/90, 130/85, and 130/80 mm Hg respectively. Hypertension prevalence increased with age, reaching a rate of 94.4% in patients aged 80 years or more when the cutoff value of 130/80 mm Hg was used. At this cutoff, 93.3% and 86.6% of patients with a body mass index over or under 30 kg/m(2), respectively, were diagnosed with hypertension. As hypertension appears to eventually afflict the vast majority of diabetic patients, the minority of subjects not developing hypertension emerges as a unique group, which potentially deserves further in-depth study.
