Extra vitamin supplements can reduce the risk of having an underweight
or undersized baby, and all pregnant women in developing countries
should get them, researchers said on Wednesday.

But the team, reporting in the New England Journal of Medicine, said
the supplements did not lower the likelihood of premature birth or
losing the fetus before birth.

The study, conducted in Dar es Salaam, Tanzania, involved 8,468
pregnant women who were free of the AIDS virus and who received iron
and folic acid supplements, both proven prenatal treatments. Half were
given supplements containing vitamins C, E and a mix of B vitamins.
The rest got placebos.

The fetal death rate stayed around 5 percent and the rate of premature
delivery was nearly 17 percent regardless of whether mothers got the
vitamins, the team, led by Wafaie Fawzi of Harvard University's School
of Public Health, reported.

But the risk of having a low birth-weight baby dropped from 9.4
percent among the placebo recipients to 7.8 percent for the babies
whose mothers took the supplements.

"In light of these findings, we recommend that multivitamins be
considered for all pregnant women in developing countries, regardless
of their HIV status," Fawzi said in a statement.

His team previously found supplements saved the lives of babies of HIV-
infected women.

About 20 million low birth-weight babies are born each year, 96
percent of them in developing countries. Babies of low birth weight,
defined as less than 5.5 pounds (2,500 grams), are more likely to die
young, have growth and learning difficulties and may later be prone to
diabetes and heart disease.

"Many developing countries have a system for providing prenatal iron
and folate supplements; the supplements are produced in bulk by the
United Nations Children's Fund at an estimated cost of less than $1
per person for the duration of the pregnancy," the researchers wrote.

Adding the extra vitamins, they said, would probably increase that
cost by just 20 cents, "and scaling up prenatal multiple micronutrient
supplementation could be a highly cost-effective approach to improving
both outcomes among pregnant women in developing countries."
