Planning to study geophagy in pregnant mothers and its effects on child development

Official title: Planning Grant: Developing the Research Capacity to Investigate the Practice of Geophagy Among Pregnant Mothers and Impacts on Children's Neurodevelopment

Funded at Oregon State University · NIH-11554855 · Data updated 2026-11-12

This project plans to collaborate with partners in Zambia to explore if eating earth during pregnancy affects a child’s brain development.

Who could benefit from this research

Could help

Pregnant people in sub-Saharan Africa (Ndola, Zambia) who report geophagy during pregnancy and have HIV-negative status.

Less likely to help

Pregnant individuals who do not engage in geophagy or who are HIV-positive may see limited direct benefit from this planning grant.

What this research studies

A planning grant will build capacity to study geophagy and its possible effects on neurodevelopment in children. The team will train researchers at partner sites and test children’s development using Bayley-4 assessments. The study will screen 200 HIV-negative pregnant women to understand geophagy practices, metal exposure, and potential developmental outcomes in their children.

Why it matters

Potential benefit: If successful, the work could improve understanding of maternal soil-eating and help protect child neurodevelopment through targeted guidance and interventions.

How similar studies have gone: There is prior evidence linking maternal geophagy and heavy metal exposure to developmental outcomes, but direct translational pathways remain understudied in this region.
