Relationship between anaemia, iron and folacin deficiency, haemoglobinopathies and parasitic infection.
Iron status, folacin status, haemoglobinopathies, malarial infection and intestinal parasitosis frequencies were assessed in a representative sample of 586 subjects living in a rural district of South Benin. Anaemia according to WHO reference values for haemoglobin was observed in 42 per cent of subjects. The prevalence was higher in children and menstruating women. Iron deficiency, defined by two or more abnormal values in the four independent indicators of iron status used (transferrin saturation, erythrocyte protoporphyrin, serum ferritin, and mean corpuscular volume) was present in 30 per cent of subjects. Half of the anaemias were associated with iron deficiency. Folate deficiency was associated with anaemia in 20 per cent of subjects. Anaemia, iron and folacin status were not significantly related to the degree of malarial infection nor to the type of haemoglobin. Although hookworm infection was very common, there was no significant relationship between egg count and haemoglobin level or haematological parameters of iron and folacin status. The lack of correlation can be explained by the low wormload observed.
