Women's health: pregnancy and childbirth. Progress on key issues in maternal nutrition

Great progress on key issues in maternal nutrition has been made in the past few years, mainly because of the legislative requirements of the U.S. Department of Agriculture's Special Supplemental Food Program for Women, Infants, and Children (WIC Program). These advances are most timely because of the general recognition that, in this period of finite resources, we will need to make optimal use of resources such as the food package, nutrition education, and health services that together make up the WIC Program benefits. Major progress has been made in the following critical areas: (a) agreement on nutritional risk criteria; (b) identification of dietary risk factors; (c) increased availability of a variety of computer-assisted techniques for collecting, managing, and analyzing dietary intakes on large numbers of patients; and (d) recognition of the need for and availability of a variety of alternative dietary standards in the provision of overall services to pregnant women. Of even greater importance is the recognition that we can no longer treat nutrition as a single variable, independent of the many other forces that together influence the course and outcome of a pregnancy. Rather, we recognize that there is a seamless web of influences, all of which need to be taken into account in attempts to provide for the needs of pregnant women at risk of poor pregnancy outcomes. The timely application of all of these advances will greatly facilitate a more efficient and effective use of resources such as are provided by the WIC Program. They will also provide both the patients and their health care providers with more realistic expectations of what might be accomplished towards improving the outcomes of pregnancies at nutritional risk.
