Description
- Abstract
- In low-resource settings, undernutrition and infections during the first 1000 days of life are prevalent, modifiable risk factors that may have lifelong effects on a child's cognitive and psychological development. The rapidly developing fetal brain has increased nutritional and metabolic demands and is highly susceptible to the effects of inflammation. Protein, energy, and iron are key nutrients required for early brain development; yet, among women of reproductive age in sub-saharan africa, 10% are underweight and 20% have iron deficiency anemia. Pregnancy infections are also common in africa, where one in three women have a GEO-helminthic infection, contributing to iron deficiency and inflammation. Hepcidin, a regulator of iron homeostasis, is stimulated by inflammation, yet there is limited research on hepcidin in pregnancy and how to optimize fetal iron bioavailability in the context of inflammation. Understanding the complex relationship between nutrition, inflammation, and neurodevelopment is a major research GAP. The predominant approach to understanding mechanisms of prenatal brain development is derived predominantly from animal and observational studies. Here, we present an unprecedented opportunity to leverage an ongoing, independently funded randomized controlled trial (RCT) to examine casual relationships and rigorously investigate biological pathways by which prenatal nutrition and inflammation influence human fetal brain development in an undernourished and high- risk population in rural ethiopia. In the parent trial, women in early pregnancy are randomized to receive: 1) standard prenatal care, 2) a package of strengthened nutritional support (iron-folate, iodized salt, fortified balanced energy protein (BEP) supplement), 3) a package of infection management (deworming, treatment of urinary tract infections), or 4) both packages. The proposed project will support advanced, multi-modal, infant neurodevelopmental assessments (EEG/VEP, cranial ultrasound, neurologic exam, elicited imitation tasks) at 6 and 24 months of age, and analysis of maternal and newborn cord blood for inflammation biomarkers (C- reactive protein, alpha-1 acid glycoprotein, interleukin (IL)-6), neurotropic factors (IL-6 soluble receptor), iron stores (serum ferritin, soluble transferrin receptor, total body iron), and hepcidin. Our specific aims are to: (1) determine the effects of interventions on offspring neurodevelopment, (2) investigate the effects of interventions on maternal-newborn iron and inflammation biomarkers, and (3) examine the role of maternal- newborn iron status and inflammation on child neurodevelopment. Leveraging an ongoing RCT in ethiopia, we will determine the effects of iron, BEP, and inflammation on advanced measures of childhood neurobehavior and function and will deepen the understanding of biological pathways and intervention targets. We will elucidate the complex dynamics of iron and inflammation in pregnancy and their effects on neural networks, brain structure, and behavior in childhood. Our work will help optimize prenatal intervention strategies to improve early human brain development in high disease burden and vulnerable populations globally.
