Abstract
BACKGROUND
Better early childhood nutrition improves schooling, adult health, skills, and wages, but there is little evidence regarding its effect on the next generation.
OBJECTIVE
We assessed whether nutritional supplementation in children aged <7 to 15 y affected their children's nutritional status 29-38 y later.
DESIGN
We studied 791 children 0-12 y who were offspring of 401 Guatemalan women who had participated as children in a nutritional supplementation trial in which 2 villages were randomly assigned to receive a nutritious supplement (atole) and 2 were assigned to receive a less-nutritious supplement (fresco). We compared anthropometric indicators between the offspring of mothers exposed to atole and the offspring of mothers exposed to fresco.
RESULTS
Compared with the offspring of women exposed to fresco, the offspring of women exposed to atole had a 116-g (95% CI: 17, 215 g) higher birth weight, were 1.3-cm (0.4, 2.2 cm) taller, had a 0.6-cm (0.4, 0.9 cm) greater head circumference, had a 0.26 (0.09, 0.43) greater height-for-age z score, and had a 0.20 (0.02, 0.39) greater weight-for-age z score. The association for height differed by offspring sex. Sons of women exposed to atole were 2.0-cm (95% CI: 1.0, 3.1 cm) taller than the sons of women exposed to fresco. Supplementation was not associated with 6 other offspring anthropometric indicators that reflect measures of adiposity. Supplementation in boys did not affect their children's anthropometric measures.
CONCLUSION
Nutritional supplementation in girls is associated with substantial increases in their offsprings' (more for sons) birth weight, height, head circumference, height-for-age z score, and weight-for-age z score.
