The Effects of Improved Nutrition in Early Childhood on Adolescent and Early Adulthood Body Size, Composition, Maturity, and Function: Results From the First INCAP Follow-Up Study.

The first follow-up study of the original Institute of Nutrition of Central America and Panama Longitudinal Study was conducted in 1988 to 1989 when participants were between the ages of 11 and 27 years. The longer term effects of the original supplementation in early life of either high protein and energy, , or no protein and low energy, , were seen in anthropometry, skeletal maturation, physical work capacity, and intellectual development, with maximum benefit seen in those participants who had maximum exposure to the supplementation during prenatal and early postnatal years. No effects were observed in bone mineralization and menarche. The long-term positive effects are consistent with the promotion of improved nutrition during the first 1000 days and established the foundation for further follow-up studies as the participants move into adulthood and further develop their human capital.
