Abstract
The prevalence of iron deficiency anaemia in Karachi, Pakistan, was examined in a group of 100 children, aged 2 to 6 years, and 200 adult females, aged 17 to 35 years. Anaemia, defined as a haemoglobin level less than 11.5 g/dl, was present in 47% of the children and 30% of the adult females. The majority of subjects had normal red cell counts and MCV, but haematocrit and MCH were below normal in one-quarter of the children and one-third of the adult females. More than half of both children and adult females had serum ferritin levels below normal. Many also had elevated iron binding capacity and reduced serum iron levels. Iron deficiency may be superimposed on folate deficiency in this population. The potentially serious consequences and higher prevalence of iron deficiency anaemia in children and women of childbearing age demand greater efforts toward diagnosis and eradication in developing countries.
