A preliminary baseline survey was conducted to estimate the prevalence of anaemia in a group of 391 children aged 6-60 months, randomly selected from three urban slums of Karachi. Haemoglobin and the red cell indices including haematocrit, MCV, MCH, MCHC, RBC and red cell distribution width (RDW) were estimated for each of the selected children. Ferritin estimation was done on 354 (91%) children to assess the iron storage status. ⋯ Of the 354 ferritin estimations, 225 (64%) children had ferritin levels lower than normal (less than 11 ng/ml) and 128 (36%) had ferritin levels within normal limit (11-120 ng/ml). From this group, a total of 61% (214/354) children were classified as microcytic hypochromic (MIH) and 11% (39/354) of which had normal ferritin levels suggesting the presence of thalassemia minor trait. The overall results obtained indicate that iron deficiency anaemia is highly prevalent among these children.
