How childhood nutrition affects health, thinking, and life outcomes by middle age
The impact of early-life nutrition on socioeconomic status, physical health and cognitive function through middle age
This project compares people who got extra nutrition as children with those who did not to understand differences in health, thinking, and life outcomes in middle age.

What this research studies
This project follows people who took part in a nutrition program in Guatemala that began in 1969 and compares those who received supplements as children with those who did not. Researchers will use decades of follow-up data and recent health and cognitive measures collected when participants are 47–64 years old to look at physical health, thinking skills, and socioeconomic outcomes. They will examine both current levels and changes from early adulthood to middle age to see how early nutrition shaped long-term aging. Because the original program randomly assigned supplementation, the results can more clearly link childhood nutrition to later-life outcomes.
Who could benefit from this research
Good fit: Ideal candidates are adults now in their late 40s to mid-60s who were participants in the original Guatemalan nutrition trial or had documented early-life nutrition interventions like it.
Not a fit: Young children, people outside the middle-age range, or those without documented early-life nutrition exposure are unlikely to directly benefit from participating in this specific project.
Why it matters
Potential benefit: If successful, this work could show whether improving childhood nutrition helps reduce age-related declines and inform programs that boost lifelong health and functioning.
How similar studies have performed: Prior research has linked childhood undernutrition to worse schooling, cognition, and earnings in early adulthood, but extending those findings into middle age using experimental long-term data is less common.
