Abstract: This study aimed to estimate the prevalence of Iron Deficiency Anaemia (IDA), after a supplementation strategy applied to combat IDA in Moroccan pregnant women and to establish the association between iron status, diet and pregnancy outcome. The study was conducted on an agricultural community of pregnant women. Information about socio-economic status, iron supplement use and dietary habits were recorded. Blood samples were collected to determine Haematocrit (Ht), Haemoglobin (Hb) and Serum Ferritin (SF) levels and pregnancy outcome characteristics were registered. Anaemia and IDA prevalence were high and most of women had either depleted or low iron stores. Energy and nutrient intakes assessment showed that iron and folate consumption was below the two-third of the RDA. Intakes of meat, energy and calcium were lower and that of tea was higher in anaemic compared to non-anaemic women. Women with IDA presented the poorer diet. There was no significant differences of hb, ht and SF means in women who were iron supplemented (37.1% of the population) and those who were not. Newborns from anaemic and IDA mothers had lower Birth Weight (BW) than nonanemic women, however no correlation could be found between BW and haematological parameters or nutrient intakes. The results show also that anaemia and IDA affected mostly women with low socio-economic status and poor diet. The study data indicate the necessity to increase women awareness and argue for an adequate strategy such as food fortification to eradicate iron deficiency anaemia.
