Effect of Prenatal Nutritional Supplementation on Birth Outcome in Hounde District, Burkina Faso

Low birth weight (LBW; birth weight\<2,500g) is the most important determinant of mortality and morbidity in the neonatal period. It is also a very important factor in predicting nutritional status, health and development in childhood. It even influences health in adult life, contributing to the vicious cycle of disease and poverty. The high rate LBW in DCs represents therefore a major public health problem. Maternal chronic energy deficiency is assumed to be a major determinant of the problem in these countries along with prenatal micronutrient deficiencies. A large body of recent evidence points out that multiple micronutrient supplementation as such has only a modest beneficial effect on fetal growth. Therefore, it is expected that providing these multiple micronutrients in a food supplement covering energy requirement needs of pregnant women will have an effect of public health importance on children's health. This study has the objective of improving children's health by improving birth outcome and fetal growth through the provision of a food supplement enriched in multimicronutrients during pregnancy. This research includes 2 constituents: 1. a pilot phase during which dietary behavior of pregnant women is assessed as a component for optimal fetal growth 2. a randomized, placebo-controlled trial, including 1300 pregnant women aimed at testing 2 hypotheses: supplementing pregnant women with a food supplement containing a multivitamin-minerals mix will improve fetal growth; improved fetal growth will have a positive effect on health and growth during infancy. The trial is planned in Hounde District, Burkina Faso, in collaboration with Centre Muraz, which plays a leader role in research and services providing at the district level and in policy recommendations at the national level. This will ensure that the study findings are incorporated into on-going district programs with possible replication at the national level. The research lasts from February 2006 to
