Abstract
The prevalence of hypertension in a representative sample (n=10202) of the Danish general population aged 16–59 years was assessed to 4.4% based on three blood pressure readings. In Type 1 (insulin-dependent) diabetic patients of similar age (n=1703) the prevalence was determined in a similar way to 14.7% (pppp<0.03), indicating that the two groups were also different with respect to other microangiopathic lesions. Patients with essential hypertension were defined as having a normal urinary albumin excretion before and during antihypertensive treatment (if any). They were followed-up for a 58 (6–234) month period. We confirmed that hypertension is more common among Type 1 diabetic patients than in the general population and found the prevalence of essential hypertension similar in Type 1 diabetic patients to the non-diabetic population. This supports our hypothesis that hypertension is very unlikely to be the cause of diabetic nephropathy.
