Better early childhood nutrition improves schooling, adult health, skills, and wages, but there is little evidence regarding its effect on the next generation. This study assessed whether nutritional supplementation in children aged <7 to 15 y affected their children’s nutritional status 29–38 y later. The study concludes that 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.
