Effects of Maternal Vitamin D Levels on Prematurity: Feasibility Study in a Multicenter Observational Pilot.

What Was Tested

This observational study looks at Vitamin D, K2, Magnesium and Zinc.

The project includes a large-scale multicenter observational study, targeting a minimum initial sample size of 1800 participants.

This paper describes the pilot study aimed at assessing the feasibility of the full-scale study.

Who Took Part

According to the abstract, 1800 participants were involved.

The age groups tagged for this paper are adults, women only.

Feasibility was assessed through predefined outcome indicators and success criteria.

How the Study Was Run

The researchers set it up as a multicenter and pilot study.

Running at several centres spread the Vitamin D, K2, Magnesium and Zinc study over different clinics and patient groups.

It is described as a pilot, a small early test of whether a larger Vitamin D, K2, Magnesium and Zinc study would be practical.

What Was Measured

This paper describes the pilot study aimed at assessing the feasibility of the full-scale study.

Data collection included 67 parameters: 37 obtained from a questionnaire and 30 from clinical records, with particular focus on maternal 25(OH)D levels and maternal-infant health outcomes.

PubMed files the paper under topics including Pilot Projects, Feasibility Studies, Vitamin D Deficiency, Vitamin D, Premature Birth, Pregnancy Complications and Infant, Premature.

The authors tagged it with the keywords feasibility study, maternal vitamin D levels, prematurity and public health.

What This Means in Plain Language
