Abstract
Objective: To investigate the prevalence and socio-demographic factors associated with iron deficiency anaemia among blood donors in Sokoto, North Western, Nigeria using a combination of haemoglobin haematocrit and serum ferritin measurements. Methods: One hundred and fifty consecutively recruited whole blood donors, comprising of 148 (98.7%) family replacement donors and 2 (1.3%) voluntary non-remunerated donors aged 18-60 years and mean age 39±21 years constituted the subjects for this study. The full blood count was carried out using Mythic 22 CT fully automated haematology analyser (Orphee SA, Switzerland). Serum was tested for ferritin using a human ferritin enzyme immunoassay kit- ACCU Diag™ ELISA Ferritin kit (Diagnostic Automation/Cortez Diagnostic Inc. California, USA). Results: The prevalence of anaemia (haemoglobin<11.0 g/dL) was evident in 24 (16%) and iron deficiency anaemia (serum ferritin<12 ng/mL+haemoglobin<11 g/dL) in 5 (10%) of donors. The haemoglobin and ferritin levels was significantly lower among regular voluntary remunerated blood donors (13.50±0.00 and 34.88±0.00) compared to family replacement donors (14.10±2.40 and 74.12±45.20) respectively (P=0.01 and 0.05 respectively). The mean haemoglobin and ferritin level was compared among donors based on gender. The haemoglobin and ferritin was significantly higher among male donors (14.20±2.00, 78.02±49.10) compared to female donors (12.35±2.5 and 42.20±32.13) (P=0.01). The mean haemoglobin and ferritin level was compared among donors based on occupational groups. The haemoglobin and ferritin was significantly higher among civil servants compared to farmers and students (P=0.01). Conclusions: Iron deficiency anaemia is prevalent among blood donors in Sokoto, North Western, Nigeria. There is need to include routine ferritin in the blood donor testing protocol in the area to enable the diagnosis of donors with latent iron deficiency anaemia to facilitate iron supplementation for regular blood donors at risk and those with iron deficiency anaemia. journal homepage: www.jclmm.com
