In recent years there is growing interest on the role of long chain ?-3 polyunsaturated fatty acids (?-3 LC-PUFA) in pregnancy and the growth and development of the offspring. We aim to characterize and provide baseline data on the intake of LCPUFA (?-3 and ?-6) in a prospective cohort of 829 pregnant Indian women and report asso-ciations between LCPUFA intake and erythrocyte membrane phospholipid fatty acid concentration in a sub-group at baseline (1st trimester), the 2nd and 3rd trimesters of pregnancy. The dietary intake of all the macronutri-ents and of a-linolenic acid(ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) significantly increased over the 3 trimesters of pregnancy while that of ?-6 fatty acids (FA) remained unchanged. Median ?-3 FA intakes of ALA, EPA and DHA, however, were on average low at 0.56, 0.003 and 0.011 g/d, respectively while LA was 14.6 g/d during pregnancy. Consequently, the intake ratio of ALA to LA in the women in the pre-sent study was very low at 1:26. A significant decline in erythrocyte membrane arachidonic acid (AA) concen-tration but not of DHA was observed throughout pregnancy. This might be due to increased efficiency in terms of elongation of parent ?-3 FA. Dietary methods for improving the consumption of ?-3 FA need to be consid-ered in the diets of young women as well as during pregnancy. As newborns primarily depend on placental trans-fer of ?-3 FA there is need to examine the ?-3 LC-PUFA concentration in infants of mother’s with low intakes of ?-3 FA.
