Effect of iodized salt in pregnancy and lactation on infant neurodevelopment in rural Ethiopia

NIH-funded research Brigham and Women's Hospital · NIH-11336204

What this research studies

If I join, I would be enrolled in a trial in rural Ethiopia that builds on an existing pregnancy trial and adds a lactation intervention. Women are randomized using a 2x2 factorial design to receive strengthened nutrition support that includes monthly iodized salt and/or infection-control measures during pregnancy and lactation. My baby would have scheduled checks of early neurodevelopment (like attention, fine motor skills, language, and memory) and biological samples may be collected. The team follows mothers and infants through early infancy to compare developmental outcomes between groups.

Who could benefit from this research

Good fit: Pregnant women in rural Ethiopia with mild-to-moderate iodine deficiency who are in late pregnancy and plan to breastfeed, and their infants, would be the ideal participants.

Not a fit: People who are not pregnant or breastfeeding, those living outside the study area, or those already receiving adequate iodine are unlikely to benefit directly from joining.

Why it matters

Potential benefit: If successful, this could reduce iodine-related brain development problems and improve babies' early cognitive, motor, and language abilities.

How similar studies have performed: Iodine treatment for severe deficiency has clear benefits for child development, but results are mixed and less certain for mild-to-moderate deficiency and during lactation.
