Vitamin D status in pregnant women with asthma and its association with adverse respiratory outcomes during infancy.

What Was Tested

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

Vitamin D may influence pregnancy and infant outcomes, especially infant respiratory health.

Who Took Part

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

Pregnant women with asthma, recruited from John Hunter Hospital Newcastle Australia (latitude 33°S), had serum total 25-hydroxyvitamin-D (25(OH)D) measured at 16 and 35 weeks gestation.

How the Study Was Run

In design terms this was a randomized study.

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

Infant respiratory outcomes were collected at 12 months by parent-report questionnaire.

What Was Measured

Vitamin D may influence pregnancy and infant outcomes, especially infant respiratory health.

The subject headings attached to it are Asthma, New South Wales, Respiratory Sounds and Vitamin D.

The authors tagged it with the keywords infant and pregnancy.
