NCT04629534

Brief Summary

The overall goal of this study is to assess maternal vitamin D status along with diet, and milk composition, and in turn, to evaluate if infant vitamin D status can be improved with increased maternal supplementation and diet education. The central hypothesis is that by maximizing maternal vitamin D status in breastfed, preterm infants (\<35 weeks), there will be an increase infant 25(OH)D status at 1,2, and 3 months of age.

Study Arms (2)

Group A

EXPERIMENTAL
Drug: High dose Cholecalciferol

Group B

PLACEBO COMPARATOR
Drug: Cholecalciferol

Interventions

Mothers in experimental group will receive 6,000 IU of vitamin D in addition to their prenatal vitamin, daily for 3 months. Infants in this group will receive placebo vitamin D drops

Also known as: 6,600 IU of cholecalciferol
Group A

Mothers in placebo control group will receive 600 IU of vitamin D in the form of their prenatal vitamin along with placebo vitamin D. Infants of the mothers in this group will receive standard 400 IU of vitamin D

Also known as: 600 IU of cholecalciferol
Group B

Limitations and Caveats

Early termination leading to a small number of subjects analyzed with difficulty in enrollment. Technical issue with calculating total vitamin D intake through formula fortification and TPN along with the study drugs which can skew our data.
