Anemia in chronic kidney disease (CKD) is associated with poor overall outcome if not promptly managed with erythropoietin when indicated. This study assessed iron status and associated factors in predialysis CKD patients in Southern Nigeria. This was a cross-sectional study that assessed and compared iron status in 100 predialysis CKD patients and 90 healthy controls. Mean age of the CKD patients was 49.39 ± 14.84 years. Iron deficiency was present in 14% of CKD patients compared to 3% of the controls (P = 0.021). Among CKD patients with ID, 11 (85.7%) had functional iron deficiency while three (14.3%) had absolute iron deficiency. Serum ferritin was significantly higher in the predialysis CKD patients (P = 0.001). There was no significant gender difference in iron indices among the CKD patients. Functional iron deficiency was present in 11 (11%) of the CKD patients compared to none among the control group (P = 0.003). There was no significant association between iron deficiency and age, gender, etiology, and stage of CKD. Functional iron deficiency was the predominant form of iron deficiency in our predialysis CKD patients, and there was no significant association with age, gender, stage, or etiology of CKD.
