Discussion
We found that the fetuses of pregnant women with iron
intake in the 3rd tertile (>17.04 mg) had a significantly
lower a biparietal diameter, abdominal circumference,
and femur length than the fetuses of mothers in the second
tertile of iron intake (11.49 ~ 17.04 mg). About 90%
of the highest tertile were iron supplemental users and
all the mothers who consumed iron above the UL
(45 mg) took supplements containing iron.
