Fish Oil and Vitamin D Supplementations in Pregnancy Protect Against Childhood Croup.

What Was Tested

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

Croup is a prevalent respiratory disorder in early childhood most often caused by parainfluenza virus infections.

Who Took Part

The abstract describes 736 women taking part.

PubMed indexes the participants as young children, women only.

The study was completed in the Danish population-based single-center Copenhagen Prospective Studies on Asthma in Childhood 2010 mother-child cohort, which included 736 pregnant women.

How the Study Was Run

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

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

Neither the women nor the staff measuring them knew who was on Vitamin D, K2, Magnesium and Zinc, so expectations could not easily colour the readings.

Croup was diagnosed by physicians' clinical examinations and medical record checks.

Potential mediating mechanisms were investigated using blood metabolomics, airway cytokines, and airway microbiome.

What Was Measured

Topics PubMed links to this paper include Fish Oils, Croup, Olive Oil, Fatty Acids, Omega-3, Dietary Supplements, Vitamins and Vitamin D.

Author keywords: COPSAC, PUFA and RCT.

What This Means in Plain Language

The paper is a randomized and double-blind study of Vitamin D, K2, Magnesium and Zinc in 736 women.
