Infection Status of Rural Schoolchildren and its Relationship with Vitamin D Concentrations.

What Was Tested

This randomized controlled trial looks at Vitamin D, K2, Magnesium and Zinc.

To assess the nutritional and infection status of rural schoolchildren and to study the relationship of infection status with serum 25(OH)D concentrations.

Who Took Part

The study group was 387 children.

PubMed indexes the participants as children, both men and women.

Data collected from 387 children included anthropometric, clinical, infection-related data (using a validated questionnaire) and dietary data (by 24-h recall method over 3 non-consecutive days, including a holiday) and serum 25(OH)D estimations (by ELISA).

How the Study Was Run

The design is described as randomized and double-blind.

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

Blinding on both sides kept the children and researchers unaware of who received Vitamin D, K2, Magnesium and Zinc.

This study was carried out in a primary school, in a rural setting, near Pune (18°N), Maharashtra.

What Was Measured

PubMed files the paper under topics including Anthropometry, Cross-Sectional Studies, India, Nutrition Disorders, Nutritional Status, Prevalence and Respiratory Tract Infections.

Author keywords: 25(OH)D, Vitamin D status and Vitamin D sufficient, Vitamin D insufficient.

What This Means in Plain Language

The paper is a randomized and double-blind study of Vitamin D, K2, Magnesium and Zinc in 387 children.

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