 The results of this meta-analysis suggest that approximately half of all diabetic patients in Iran suffer from hypertension. Diabetic patients with type 1 diabetes had a higher rate of hypertension compared to those with type 2 diabetes. There was no significant decrease in the prevalence of hypertension among diabetic patients in Iran over the last few years. Furthermore, diabetic patients living in northern Iran were found to be more likely to have hypertension than those living in other regions of the country.
