The effects of a nutrition intervention program during pregnancy: Phase two.

This study sought to identify the effects of an individual prescription for protein and kilocalorie requirement during pregnancy on subsequent maternal and infant outcomes using an experimental control group with 29 subjects in phase one and 18 subjects in phase two. The method of Nutrition;al counseling was not found to have a significant impact on increasing the amounts of protein and kilocalories consumed by the experimental group in phase two; findings indicate that those subjects who ate an adequate amount of both protein and kilocalories did not have significantly larger birth weight infants than those who had inadequate Nutrition;al intake (p=.10, two-tailed test. Twin births excluded). However, those women who had an adequate early weight gain in addition to adequate prescription ingestion as compared to those with inadequate early weight gain and inadequate prescription ingestion, gained significantly more weight (p=.000720 and showed a trend toward higher birth weight infants (p=.09, two-tailed test, twin births excluded).
