Abstract: Study Objective:The objective was to quantifycisandtransfatty acids in maternal plasma and infant cord plasma from adolescent mothers. Design:From 80 adolescent healthy mothers, we sampled postpartum maternal blood and umbilical cord blood at birth.Transfatty acids (tFAs), linoleic (18:2), and arachidonic (AA, 20:4) acids of the n-6 family, anda-linolenic (18:3), eicosapentaenoic (20:5) and docosa-hexaenoic (22:6) acids of the n-3 family were analyzed by gas-liquid chromatography. Results were expressed as a percentage of total fatty acids. Results:Linoleic fatty acid was present in greater proportions in the maternal plasma than in that of the umbilical cord, whereas AA was present in greater proportions in the total lipids of umbilical cord blood. Docosahexaenoic acid was the long-chain polyunsaturated fatty acid of the n-3 family that was predominant in both maternal and umbilical cord plasma. ThetFAs in the maternal plasma had a negative correlation with oleic acid and linoleic acid. Linolenic acid had a positive correlation with cephalic perimeter upon birth. A tendency for a negative correlation betweentransisomers and gestational age at birth (P5.05) was observed. Conclusions:Long-chain polyunsaturated fatty acids, which are important to fetal growth and development, were found in greater quantities in the cord blood of newborns of adolescents than in the maternal blood, indicating a priority of transfer of AA and docosa-hexaenoic fatty acids to the fetus. Despite the lower levels oftFAs found in maternal blood, we verified potential risk for premature birth.
