Preterm Infants on Early Solid Foods and Vitamin D Status in the First Year of Life-A Secondary Outcome Analysis of a Randomized Controlled Trial.

What Was Tested

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

The aim of this study was to examine whether two timepoints for the introduction of solid foods in preterm infants have an impact on vitamin D status in the first year of life.

Why It Was Studied

Preterm birth places infants at high risk for mineral and micronutrient deficiencies important for bone health.

This is a secondary outcome analysis of a prospective, randomized trial on very low birth weight (VLBW) infants, randomized to an early (10-12th week corrected age) or a late (16-18th week corrected age) complementary-feeding group.

Who Took Part

The study group was 177 infants.

By PubMed's age tags, the people studied were infants, women only.

How the Study Was Run

The design is described as randomized.

Random assignment meant chance, not the researchers, decided who got Vitamin D, K2, Magnesium and Zinc and who got the comparison, which limits bias.

Vitamin D status was assessed by blood samples taken at 6 weeks, 6, and 12 months corrected age.

What Was Measured

This is a secondary outcome analysis of a prospective, randomized trial on very low birth weight (VLBW) infants, randomized to an early (10-12th week corrected age) or a late (16-18th week corrected age) complementary-feeding group.
