Using systematic random sampling, a structured questionnaire, which comprised of questions on social demographic characteristics and past and current clinical history, was administered followed by measurement of creatinine and urinary protein and glucose. Estimated glomerular filtration rate (eGFR) was estimated using CKD-epidemiology formula without race as a factor. Baseline eGFR between 60– 89 min/mL/1.73m2 and < 60 min/mL/1.73m2 defined reduced eGFR and renal impairment, respectively. Estimated GFR less than 60 min/mL/1.73m2 measured two times at least 3 months apart was used to define CKD.Results: Ninety-six percent (n = 304) patients out of 317 patients were included in the study. Among all included patients, only 3.9% (n = 12) had eGFR of 90 min/mL/1.73m2 and above. The prevalence of renal impairment and CKD was 52% (158/304, CI 46.2– 57.7) and 29.9% (91/304, CI 24.8– 34.5), respectively. In adjusted logistic regression analysis, currently taking herbal medications as treatment of hypertension (OR 4.11 (CI 1.14– 14.80), p = 0.03) and being overweight and/or obese (OR 2.16 (CI 1.24– 3.78), p < 0.001) was associated with CKD. Additionally, receiving some education was associated with a 48% (OR 0.52 (CI 0.29– 0.91), p = 0.02) reduced likelihood of CKD.Conclusion: The prevalence of renal impairment and CKD is high among hypertensive patients in rural Sierra Leone. CKD was associated with current history of taking herbal medications and being overweight and/or obese. Additionally, CKD was associated with reduced likelihood in patients who received some education.Keywords: hypertension, non-communicable diseases, CKD, renal impairment, screening, Sierra Leone
