In this issue of the IRCD Bulletin is reviewed the status of research relating to health, nutrition, and learning as pertaining to children from economically disadvantaged families. At present there is considered to be little hard evidence in support of the notion that children's present biological condition is correlated with their learning. The question thus remains as to whether it is rational (or humane) to attempt to teach a child who is hungry, ill, or, tired. If not, then health and nutritional programs should be instituted as the one sensible course of action, and not merely because they may be based on scientific research findings. Also included in this issue of the Bulletin is an article on the recommendations for child health care, which has been reprinted from the"Bulletin of Pediatric Research," Volume 4, November 1970, with the permission of the American Academy of Pediatrics.
