ORIGINAL RESEARCH COMMUNICATION
Effect of iron supplementation during pregnancy on the intelligence
quotient and behavior of children at 4 y of age: long-term follow-up of
a randomized controlled trial1,2,3

Pediatrics (SJZ, RAG, and MM), the Department of Obstetrics &
Gynaecology (CAC and MM), and the Departments of Paediatrics and Public
Health (PB), Women's & Children's Hospital, university of Adelaide,
North Adelaide, Australia.
Background: Iron supplements are often prescribed during pregnancy
despite the lack of intervention trials that have assessed the effects
of supplementation in pregnancy on childhood development.
Objective: The objective was to determine whether iron supplementation
during pregnancy influences childhood intelligence quotient (IQ) in an
industrialized country.
Design: Pregnant women (n =3D 430) were randomly allocated to receive
iron (20 mg/d) or placebo from 20 wk gestation until delivery, and the
women and their children were followed up over the long term (4 y).
Seventy percent of these families participated in the follow-up. The
proportion of women with iron deficiency anemia at the end of pregnancy
was 1% (2 of 146) in the iron group and 11% (15 of 141) in the placebo
group. The primary outcome was the IQ of the children at 4 y of age, as
assessed by the Stanford-Binet Intelligence Scale. Secondary outcomes
included child behavior and the general health of the mothers.
Results: The mean IQ was not significantly different (P =3D 0.980)
between the children of the iron-supplemented mothers (109 =B1 11; n =3D
153) and the children of the mothers in the placebo group (109 =B1 11; n
=3D 149). However, the percentage of children with an abnormal behavior
score was higher in the iron group (24 of 151, or 16%) than in the
placebo group (12 of 149, or 8%); the relative risk was 1.97 (95% CI:
1=2E03, 3.80; P =3D 0.037). There was no significant difference in the
health of the mothers between groups, as assessed by the SF-36 Health
Survey.
Conclusions: Prenatal iron supplementation that reduces the incidence
of iron deficiency anemia from 11% to 1% has no effect on the IQ of the
offspring at 4 y of age.
Key Words: Iron supplementation =B7 pregnancy =B7 child development =B7
intelligence quotient =B7 IQ =B7 behavior =B7 industrialized country

As the statistics are all important here, would you discuss and interpret
the statistical results. Iron had 16 percent and not iron had 8 percent.
This means 84 percent of iron didn't have a high score, why not if iron is
to be considered as the cause and why did it appear in not iron also? Why
aren't the results 100 percent each way and a black and white outcome
clear?

| Keep in mind, this could have POTENTIALLY been a SYNTHETIC form of iron
suppliment OR even an inefficient form of iron (rather than a high
quality grade of iron).
All these would have potential referance to the study and were probably
not taken into consideration.
I may be wrong in that I am not even certain if there is a synthetic
form of iron on the market, however I do know that most suppliments on
the market (created by Big Pharma) are all synthetic (cheap stripped
down version of a vitamin or mineral).

| Ferrous sulphate was used in the study. FeSO4 is FeSO4 any way you
look at it unless you're talking about hydration.
