PREMATURELY born children of low birth weight have been reported to lag in physical development when compared either to full-term infants or to prematurely born children of higher birth weight.1-6 Cherry et al7 reported on weight, height, and head measurements during the first year of life of normal prematurely born Negro infants divided into weight groups of 1,001-1,500 gm and 1,501-2,000 gm. The children of lower birth weight were shorter and less heavy one year after birth. Furthermore, these children were shorter than full-term Negro children studied by Scott.8 Drillien9 found that children of higher birth weight tended to maintain height and weight advantages at 2 years of age although the differences in height or weight between full-term and premature children or among groups of prematurely born children were found not to be significant. Among infants of similar birth weight, poorer gains were noted for those of lower socioeconomic
