Maternal zinc supplementation and growth in Peruvian infants.

What Was Tested

The paper reports a study of Vitamin D, K2, Magnesium and Zinc, published as a randomized controlled trial.

The researchers aimed to assess the effect of maternal zinc supplementation during pregnancy on infant growth through age 1 y.

At birth, 546 infants were followed for 12 mo to assess growth.

Why It Was Studied

Little is known about how maternal zinc intake influences growth in utero and in postnatal life in humans.

Who Took Part

The study group was 546 infants.

The age groups tagged for this paper are infants and adults, both men and women.

A double-blind, randomized controlled trial of prenatal zinc supplementation was conducted from 1995 to 1997 in Lima, Peru.

How the Study Was Run

The researchers set it up as a randomized and double-blind study.

The infants were allocated by chance, so the Vitamin D, K2, Magnesium and Zinc group and the comparison group should start out alike.

As a double-blind Vitamin D, K2, Magnesium and Zinc study, the assignments were hidden from both participants and investigators until the end.

What Was Measured

The subject headings attached to it are Dietary Supplements, Fetal Development, Infant Nutritional Physiological Phenomena, Maternal Nutritional Physiological Phenomena, Muscle Proteins, Muscle, Skeletal and Peru.

What This Means in Plain Language

The paper is a randomized and double-blind study of Vitamin D, K2, Magnesium and Zinc in 546 infants.

With several hundred people or more, it is a fairly large study for this kind of research.

Its findings take up roughly 5 sentences of the abstract and are left out here on purpose; the source paper is the place to read them.

The publication is from 2008 (The American journal of clinical nutrition), a journal based in United States.
