More infants should receive iron supplements

06.09.2010
Giving iron supplements to children with marginally low birth weights (2000-2500 grams) dramatically reduces the risk of developing iron deficiency and anemia. This is shown by Umeå researcher Magnus Domellöf and associates in the coming edition of the leading pediatric scientific journal Pediatrics.

It has recently been discovered that both birth weight and the infants’ nutrition supply are important risk factors for later morbidity in adulthood. Due to high nutritional requirements, infants with low birth weight are at risk of developing nutrient deficiencies during their first year of life, including iron deficiency. Iron is necessary for the production of hemoglobin for the blood, and also for the development of the brain. Iron deficiency in infants has been shown to be associated with poor neurological development.

The present study included 285 children with marginally low birth weights (2000-2500 g). They were randomly divided into three groups that were given different amounts of iron drops (0, 1, or 2 mg per kg daily) from the age of 6 weeks to 6 months. Among children who were given placebo drops (no iron) 36 % had iron deficiency and 10% iron-deficiency anemia at the age of 6 months, whereas the corresponding figures for children who received 2 mg of iron were 4% and 0%. At greatest risk of developing iron deficiency were those children who were fully breast-fed at the age of 6 weeks. They ran an 18% risk of developing iron-deficiency anemia by the age of 6 months if they did not receive iron drops.

The study indicates no negative effects from iron drops on the children’s growth, infections, or other morbidity. Most children with marginally low birth weights in Sweden are considered healthy and are not given iron drops, although routines differ from one hospital to another. The study indicates that these children should be given iron drops, as they otherwise run a high risk of developing iron deficiency and anemia.

What effects iron deficiency has on brain development is as yet unclear, but the Umeå researchers will be following these children up to the age of 7 years and test their intellectual development, the occurrence of behavioral problems, and attention problems in order to find out whether iron supplements for infants have any effect on brain function at school age.

The findings will have a great impact on nutrition recommendations for children with marginally low birth weights in Sweden and abroad, and they will hopefully lead to improved health in these children when they reach school age. In Sweden 3.5% of all newborns have low birth weights (under 2 500 grams), which means that some 300,000 Swedes have had a low birth weight. Most of these people had only marginally low birth weights (2000-2500 g).

The study was performed by Magnus Domellöf and his doctoral student Staffan Berglund, both with Umeå University, in collaboration with Björn Westrup, Karolinska Institute.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
