The current study evaluated the prevalence of anaemia
in pregnant women at two moments: the first was before
the mandatory fortification of flours and the second
happened at least 1 year after effective implementation of
mandatory flour fortification in Brazil. One limitation of
the present study is that it was not possible to obtain
information about adherence to the Fe1folic acid supplementation
prescribed during the prenatal period to all
pregnant women beginning in the 20th gestational
week(8). This information was not available in the medical
records from which the data were abstracted. Furthermore,
because the study is a retrospective one that uses
secondary data, it was not possible to obtain this information
through interviews with the pregnant women
