Data from intervention studies clearly indicate that maternal nutritional supplementation programs have a beneficial effect on maternal and infant health, despite an incomplete understanding of the association between maternal malnutrition and pregnancy outcome. Research areas have been defined for further study: the timing of maternal supplementation; the relationship between malnutrition and infections; indicators of nutritional status; maternal weight gain during pregnancy; selection of high-risk populations; the significance of birthweight; maternal-fetal interactions; and the role of specific nutrients. Special attention should be given to implementation of appropriate intervention programs. Governments should identify populations most in need based on community surveys. An integrated approach to improving the nutritional and health status of pregnant and lactating women and young children, using resources from many diverse sectors, is needed.
