Association of hypertension and non-insulin-dependent diabetes mellitus in the Saudi population

Background: Saudi Arabia has a high prevalence of diabetes mellitus (DM). Several studies have shown that hypertension (HT) occurs frequently in obese individuals. This study was conducted to determine the prevalence of HT in Saudi diabetic patients. Subjects and Methods: A total of 13,519 nondiabetic and 1286 diabetic adult subjects diagnosed during the National Program for the Study of DM, in which household screening was carried out, were included in the study. The diagnosis of DM and HT was based on the criteria of the World Health Organization. Results: From the total group, the prevalence of HT in nondiabetic males and females was 4.48% and 2.8%, respectively, while it was 11.44% and 15.98% in the diabetic males and females, respectively. The subjects were classified according to the province to which they belonged, and the prevalence of HT was calculated in the diabetic and nondiabetic group. In the Central, Eastern and Western Provinces, female diabetics had a significantly higher HT prevalence compared to male diabetics, however, in the Southern and Northern Provinces, the prevalence rate was almost the same. In all provinces the increase in prevalence of HT in diabetics was significantly higher in the females compared to the males. Conclusion: Since HT prevalence increases significantly in diabetics, and this association leads to several cardiovascular complications, it is necessary to adopt measures for the control of DM and HT in the Saudi population.
