Our research aims to improve health through nutrition during the critical periods of development, from pregnancy to childhood. We have a particular interest in micronutrients including vitamin D. We work to decrease health disparities among minority populations in the United States, and those participating in federal food assistance programs such as WIC.

Vitamin D Metabolism in Pregnancy
Maternal vitamin D status is an important predictor of infant status however, no scientific consensus exists on the amount of vitamin D supplementation needed during pregnancy. Women with excess obesity, and those with darker skin may have higher requirements. Using data from two pregnancy cohorts collected at the Arkansans Children’s Nutrition Center our current work examines differences in pregnancy-related changes in vitamin D metabolism among obesity-affected vs. healthy weight pregnancies. It will also explore how vitamin D status in pregnancy relates to offspring bone health. This study will help guide future work on the appropriate amount of vitamin D supplmentation needed in pregnancy.

Micronutrient Requirements in the Postpartum Period
Little is known about nutrient requirements during the postnatal period. Specifically, micronutrient deficiencies which can arise from inadequate intake or absorption of minerals and vitamins which can affect the mother and healthy growth of her offspring. Further, essential nutrients transfer to breastmilk and can affect infant development. Dietary guidance on the continuation of multivitamin-mineral (MVM) supplementation during the postpartum period is unclear. Our work is testing the effectiveness of a postpartum MVM supplement designed for the postpartum period to improve nutrition and health as compared to a placebo-control supplement.
