The prevalence of deficiency anaemias has been studied in 617 apparently healthy urban and 493 rural schoolchildren of Varanasi in North India. The subjects ranged in age from 5 to 15 years. They were randomly divided into two groups. One group received an oral haematinic preparation containing iron, folic acid, cyanocobalamin and ascorbic acid on each school day for a period of 10 weeks while the other group was given placebo over the same duration. The PCV (haematocrit) determinations were performed at the beginning and the end of the study period. The prevalence of deficiency anaemias was calculated by determining the percentage of subjects who showed a response in their PCV values, following supplementation with haematinics, which was greater than a response obtained by random factors in the placebo group. The results showed that 33.8% of the urban and 69.4% of the rural school children were anaemic.
