Prevalence, awareness, treatment and control of hypertension in adults with chronic kidney disease in Turkey: results from the CREDIT study

Abstract

Background: In the Chronic REnal Disease in Turkey-CREDIT Study, a large populationbased study on 10,748 adults, the prevalence of chronic kidney disease (CKD) and relationship between CKD and other cardiovascular risk factors had been studied.

Methods: This report presents the results of CREDIT study on the prevalence, awareness, treatment, and control of hypertension among CKD patients.

Results: The prevalence and awareness of hypertension in CREDIT population was 32.7% and 48.6%, respectively. Of the patients with hypertension, 31.5% were under treatment, and 16.4% had hypertension under control. Prevalence of CKD was 25.3% in patients with hypertension. Among CKD patients (15.7% of the CREDIT study population), 56.3% had hypertension. The prevalence of hypertension was 34.8% at stage 1, 79.8% at stage 3, and 92.3% at stage 5 CKD. Only 13.4% of patients with CKD have optimal blood pressure. Among CKD patients, 61.9% were aware of hypertension, and 44.2% were under treatment. Overall control rate of hypertension in subjects with CKD was 16.3% with the lowest rate at stage 1 (12.3%) and highest rate at stage 4 (40%). The control rate increased to 28.8% for CKD patients under treatment for hypertension.

Conclusion: As a conclusion, hypertension is highly prevalent in subjects with CKD in Turkey with suboptimal awareness, treatment, and control rates. Appropriate health strategies should be implicated to improve prevention, early diagnosis, and treatment of hypertension, which is one of the leading causes of CKD.
