The aim of this study was to answer the question whether dietary unsaturated fatty acid supplementation of pregnant women has an impact on obstetric parameters, in particular for the gestation duration and infant birth weight, length and head circumference. To analyze that problem we searched the MEDLINE database until December 2010.
