Preconceptional Lipid-Based Nutrient Supplementation In 2 Low-Resource Countries Results In Distinctly Different Igf-1/Mtor Placental Responses, Marisol Castillo-Castrejon, Ivana V. Yang, Elizabeth J. Davidson, Sarah J. Borengasser, Purevsuren Jambal, Jamie Westcott, Jennifer F. Kemp, Ana Garces, Sumera Aziz Ali, Sarah Saleem

Community Health Sciences

Background: Preconceptional maternal small-quantity lipid-based nutrient supplementation (SQLNS) improved intrauterine linear growth in low-resource countries as demonstrated by the Women First Preconception Maternal Nutrition Trial (WF). Fetal growth is dependent on nutrient availability and regulated by insulin-like growth factor 1 (IGF-1) through changes in placental transfer capacity, mediated by the mechanistic target of rapamycin (mTOR) pathway.
Objectives: Our objective was to evaluate the role of placental mTOR and IGF-1 signaling on fetal growth in women from 2 low-resource countries with high rates of stunting after they received preconceptional SQLNS.
Methods: We studied 48 women from preconception through delivery who were …
