Prevalence & etiology of nutritional anaemias in early childhood in an urban slum.

The present study was carried out to find out the prevalence and etiology of nutritional anaemia among preschool children from an urban slum. Randomly selected 300 children aged 3 months-3 yr were analysed over a period of one year for estimating prevalence of nutritional anaemia. Prevalence was also assessed by the rise in haemoglobin after 8 wk of haematinic supplementation in 159 of the 300 subjects. Ninety anaemic children were evaluated for the etiology of anaemia. Prevalence of anaemia, as judged by WHO recommended 'cut-off' value of haemoglobin < 11 g/dl, was 76 per cent while comparable value of 74.8 per cent was derived by response to haematinic supplementation. Pure iron deficiency anaemia (IDA) was detected in 41.4 per cent (37/90) of anaemic children. Vitamin B12 deficiency alone or in combination with iron was diagnosed in 14.4 and 22.2 per cent anaemic children respectively. Similarly folate deficiency, IDA with infection and anaemia of chronic diseases (ACD) was diagnosed in 2.2, 3.3 and 12.2 per cent cases respectively. Childhood anaemia continues to be a significant public health problem in preschoolers and iron deficiency is by far the commonest nutritional cause of anaemia. Vitamin B12 deficiency per se or in combination with iron is an important yet not commonly recognised cause of anaemias in preschool children in the community.
