A new formulation of small-quantity lipid-based nutrient supplements (SQ-LNS), which replaces some milk powder, peanut and sugar ingredients with egg powder and has an improved nutritional profile, will be tested with mothers beginning in the first trimester of pregnancy. Results anticipated include positive anthropometric and structural brain outcomes in Haitian newborns. Non-invasive intracranial ultrasound neuro-imaging will be used to assess infant brain development.
