The Prevalence of Hypertension and Its Progression Among Patients with Type 2 Diabetes in Jordan

Background: Assessing the prevalence and progression of hypertension among diabetics is crucial for designing appropriate strategies for successfully managing hypertension and its life-threatening complications. This study aimed to assess the prevalence of hypertension, its progression, and its determinants among type 2 diabetes mellitus (T2DM) patients in Jordan.

Materials And Methods: A cross-sectional study was conducted among 1382 Jordanian patients with T2DM in the period from January 2019 to January 2020. Blood pressure (BP) was followed and measured every 2-3 months using standardized automated sphygmomanometer during patients' routine visits for a total of 12 months. Data were obtained from medical records that included sociodemographic variables, anthropometric measurements, HbA1c, lipid profile, presence of T2DM complications and treatment.

Results: The prevalence of hypertension among T2DM patients at the baseline was 74.6% (95% CI: 72.2%, 76.9%). The one-year incidence of hypertension among T2DM patients who were free of hypertension at the baseline was 26.2% (95% CI: 21.7%, 31.1%). In the multiple logistics regression analysis, patients older than 60 years (OR = 1.3 (95% CI: 1.01, 1.7); p-value 0.045) and those with positive family history of hypertension (OR = 4.2 (95% CI: 1.2, 8.2); p-value 0.026) were more likely to have uncontrolled hypertension. Patients who were using insulin only were less likely (OR = 0.5 (95% CI: 0.2, 0.9); p-value 0.026) to have uncontrolled hypertension compared to those who were on oral hypoglycemic agents only.

Conclusion: The prevalence of hypertension among Jordanian patients with T2DM is alarmingly high. Healthcare providers should be committed to policies or preventive strategies targeting the modifiable risk factors associated with hypertension.
