Patient Awareness, Prevalence, and Risk Factors of Chronic Kidney Disease among Diabetes Mellitus and Hypertensive Patients at Jimma University Medical Center, Ethiopia

الملخص EN

Background.

There is an alarming rise of chronic kidney disease (CKD) prevalence globally, which is associated with significant morbidity and mortality necessitating special attention as one of the major public health problems.

The burden of CKD disproportionately impacts low-income countries like Ethiopia where hypertension and diabetes mellitus, the two most important risk factors for CKD growth rate, are greatest.

Objective.

The aim of this study is to assess patient awareness, prevalence, and risk factors of chronic kidney disease among hypertensive and diabetes mellitus patients.

Methods.

Hospital based cross-sectional study design was conducted at Jimma University Medical Center among adult (≥18 years) hypertensive and diabetes mellitus patients.

Informed written consent was obtained from each participant and data was collected by interview and chart review; blood and urine samples were collected for CKD screening.

Glomerular filtration rate (GFR) was estimated from serum creatinine using CKD epidemiology collaboration (CKD-EPI) equation, and CKD was defined using estimated GFR (e-GFR) and albuminuria.

Multivariate logistic regression was used to identify independent predictors of CKD and p-value <0.05 considered statistically significant.

Result.

Mean (±SD=standard deviation) age of participants was 54.81 ± 12.45 years and 110 (52.9%) of them were male.

Only 59 (28.4%) of the participants had awareness about CKD and its risk factors.

The prevalence of CKD was 26% (95% CI; 20.3%-31.8%).

Factors associated with chronic kidney disease were uncontrolled blood pressure (adjusted odds ratio (AOR)=2.22,95% CI=1.01-4.76), fasting blood sugar ≥ 150 mg/dl, (AOR=3.70,95% CI=1.75-7.69), angiotensin converting enzyme inhibitors (ACEIs) nonusers, (AOR=4.35 ,95% CI=1.96-10.0), poor knowledge of CKD (AOR=3.69, 95% CI=1.48-9.20), and long duration of hypertension (AOR=4.55, 95%CI=1.72-11.11).

Conclusion.

Our study found out low level of patient awareness and high prevalence of CKD.

The predictors of CKD were uncontrolled blood pressure, fasting blood sugar> 150 mg/dl, long duration of hypertension, ACEIs nonusers, and poor knowledge about CKD.
