This small series did not show any positive relationship between dietary adequacy and the occurrence of certain complications of pregnancy and childbirth. (a) There was no evidence that toxemia occurs in the presence of insufficient protein, vitamin A or vitamin B 1 intake. (b) There were not enough cases of abortion, hemorrhage, pyelitis and cystitis, and intercurrent infections to justify any conclusions. (c) Protein deficiency did not seem responsible for the production of premature labor in a short series of cases. The same may be said for vitamin A. (d) The number of neonatal deaths and stillbirths was too small to show any positive relationship to dietary inadequacy. (e) The diets of those women who were morbid after delivery did not differ markedly from the remainder of the group with respect to protein, vitamin A, or vitamin C intake. (f) Protein intake apparently had no bearing on the ability of the women to nurse their babies during the hospital stay.
