Effect of anaemia on cognitive function in children

0
Study was carried out on 150 school going children to study the relationship between iron deficiency anaemia and cognitive function. Children's were grouped into moderate anaemic, mild anaemic and non-anaemic. Haemoglobin levels were estimated by cyanmethaemoglobin method. Results indicate that 53.33% were mild anaemic, 12% moderate anaemic and 34.67% non-anaemic. Results significantly (p < 0.05) indicates that moderate anaemic children performed poor on attention, design fluency, verbal working memory N-back 2, visual working memory N-back 2, planning, dictation, mathematical calculations, intelligence, immediate verbal learning and visual and verbal memory. Moreover, mild anaemic children performed significantly poor (p < 0.05) in attention, visual working memory N-back 2, dictation, mathematical calculations, intelligence, immediate verbal learning and visual and verbal memory. We concluded that non-anaemic children performed significantly better on cognitive function tests than mild and moderate anaemic. All data are expressed as mean ± SD and were analysed by analysis of variance by using SPSS software.
