Our present study was associated with several limitations.
Firstly, maternal iron status in blood was not assessed in
the present study although maternal hematological parameters
such as, Hb and hematocrit levels are important ones
to be considered when we study the effect of maternal
iron intake on fetal growth [46]. Secondly, the employed
dietary intake and supplements were investigated for only
a single time. A 24-hour recall may be insufficient to postulate
that the values are from a usual daily intake due to
large intra-individual variability
