Summary

Project Viva is a long-term study that follows more than 2,000 mother-child pairs from pregnancy into the child's teenage years. Researchers measure children's growth, metabolic risk factors, and brain development, and they track mothers' weight and children's asthma symptoms. The goal is to understand how early-life factors relate to health outcomes like obesity and metabolic problems later in childhood.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If the study identifies early-life factors that predict obesity and metabolic problems, it could inform future prevention strategies and clinical guidance for mothers and children.
What could go wrong
This is an observational study, so it can show associations but cannot prove cause and effect. Findings may not apply to all families, and the long follow-up means some participants may drop out over time.

Project Viva recruited 2670 women (64% of those who were approached for participation). 2,128 were still enrolled at the time of delivery and had live births, resulting in a cohort of 2,128 mother-child pairs.
