Longitudinal observation of weight grains and concentrations of protein in the serum of 744 infants (521 full-term and 223 premature) are presented in considerable detail. The presentation of the data well illustrates the complexities of analysis of data concerning gain in weight in the first year of life. Data concerning growth in length are not presented.
Premature infants receiving a formula of
-skimmed cow's milk with added carbohydrate gained weight more rapidly than did those fed human milk. The difference was greatest with respect to infants with lowest birth weights.
