Abstract
Objective
To determine the prevalence of chronic kidney disease (CKD) and associated factors among adults with hypertension attending a tertiary cardiac clinic in Tanzania.
Design
Hospital-based cross-sectional study.
Setting
Tertiary cardiac outpatient clinic in Dar es Salaam, Tanzania.
Participants
A total of 162 adults aged ≥18 years with documented hypertension attending follow-up care from 15 June to 30 July 2024 were recruited using simple random sampling.
Main outcome measures
The primary outcome was study-defined CKD, classified from available records as estimated glomerular filtration rate (eGFR)
Results
Among 162 hypertensive patients, 34 met the study-defined CKD criteria, giving a prevalence of 21.0% (95% CI 15.4% to 27.9%). Median serum creatinine was 94 µmol/L (IQR 77–122; range 48–286) and median eGFR was 77 mL/min/1.73 m² (IQR 62–92; range 19–118); 29 (17.9%) participants had eGFR
Conclusions
Study-defined CKD was identified in about one-fifth of this tertiary-clinic hypertensive sample, and diabetes was the only independent factor identified. The estimate should be interpreted cautiously because the study was single-centre and full Kidney Disease: Improving Global Outcomes confirmation using chronicity and UACR was not available for all participants. Multicentre studies using repeated eGFR and quantitative albuminuria assessment are needed.
