The Millennium Development Goals include an aspect of children's health. The main purpose of this study was to indicate possible changes in different blood cells on one hand and secondly to establish standards of various parameters of the counts in the blood. The study involved 1,157 children aged 5 to 18 years in four selected municipalities of Abidjan. Blood sampling was done fasting in the morning, between 7 and 9 h for each child to complete blood count. In addition, an electrophoretic profile of each subject was performed from a volume of red blood cells. All observed haematological parameters in children was analyzed by a program Statistical Statsoft Windows version 7.1. The results of the study showed that all haematological parameters in children aged 5 to 18 years did not differ significantly by gender (p > 0.05) except for the red blood cells and thrombocytes. The red blood cells were significantly (p < 0.05) higher among boys (4.9 ± 0.02 × 1012/L) than girls (4.4 ± 0.02 × 1012/L). In contrast, girls (297.5 ± 5.4 × 106/L) in our study showed a significant increase in thrombocytes when compared with boys (285.6 ± 5.6 × 106/L). Morever, significant differences were observed between groups of children according to their age for red blood cells, hemoglobin, hematocrit and thrombocytes. Our investigations in these children have reported normal haematological status (11.5%) against 88.5% for abnormal haematological status. Furthermore, in all, 47% of the children presented with anaemia. The prevalence of studied children with normal hemoglobin was 84.4% against 15.6% for abnormal hemoglobin. Haematological parameters of the selected children are degraded in all. Nutrition, infectious and inflammatory syndromes and hemoglobinopathies could be the main factors.
Key words: Children, haematological status, anaemia, hemoglobin phenotype, Côte d'Ivoire.
