A community-based randomized controlled trial of iron and zinc supplementation in Indonesian infants: effects on growth and development.

What Was Tested

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

The objective of the study was to compare the effects of combined iron and zinc supplementation in infancy with the effects of iron and zinc as single micronutrients on growth, psychomotor development, and incidence of infectious disease.

Who Took Part

By PubMed's age tags, the people studied were infants, both men and women.

Anthropometric indexes, developmental indexes (Bayley Scales of Infant Development; BSID), and morbidity were recorded.

How the Study Was Run

In design terms this was a randomized, double-blind and placebo-controlled study.

The participants 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.

The comparison arm used a placebo, so changes seen with Vitamin D, K2, Magnesium and Zinc could be set against what happens without it.

What Was Measured

PubMed files the paper under topics including Anemia, Iron-Deficiency, Child Development, Community Health Services, Dietary Supplements, Drug Interactions, Factor Analysis, Statistical and Growth.
