    Input: Background / Objective : Evidence is accumulating that the long-chain PUFA ( LCPUFA ) are associated with offspring growth and body composition . We investigated the relationship between LCPUFAs in red blood cells ( RBCs ) of pregnant women/breastfeeding mothers and umbilical cord RBCs of their neonates with infant growth and body composition ⩽1 year of age . Subjects/ Methods : In an open-label r and omized , controlled trial , 208 healthy pregnant women received a dietary intervention ( daily supplementation with 1200 mg n-3 LCPUFAs and dietary counseling to reduce arachidonic acid ( AA ) intake ) from the 15th week of gestation until 4 months of lactation or followed their habitual diet . Fatty acids of plasma phospholipids ( PLs ) and RBCs from maternal and cord blood were determined and associated with infant body weight , body mass index ( BMI ) , lean body mass and fat mass assessed by skinfold thickness measurements and ultrasonography . Results : Dietary intervention significantly reduced the n-6/n-3 LCPUFA ratio in maternal and cord-blood plasma PLs and RBCs . Maternal RBCs docosahexaenoic acid ( DHA ) , n-3 LCPUFAs and n-6 LCPUFAs at the 32nd week of gestation were positively related to birth weight . Maternal n-3 LCPUFAs , n-6 LCPUFAs and AA were positively associated with birth length . Maternal RBCs AA and n-6 LCPUFAs were significantly negatively related to BMI and Ponderal Index at 1 year postpartum , but not to fat mass . Conclusion : Maternal DHA , AA , total n-3 LCPUFAs and n-6 LCPUFAs might serve as prenatal growth factors , while n-6 LCPUFAs also seems to regulate postnatal growth . The maternal n-6/n-3 LCPUFA ratio does not appear to have a role in adipose tissue development during early postnatal life Formula supplemented with docosahexaenoic acid ( DHA ) improves retinal function of preterm infants but the optimal dose is unknown . In a r and omized controlled trial we examined the effect of increasing the DHA concentration of human milk and formula on circulating fatty acids of preterm infants . Infants born <33 weeks gestation were fed high-DHA milk ( 1 % total fat as DHA ) or st and ard-DHA milk ( 0.2 - 0.3 % DHA ) until reaching their estimated due date ( EDD ) . Milk arachidonic acid ( AA ) concentration was approximately 0.5 % for both groups . At EDD , erythrocyte membrane phospholipid DHA was elevated in the high-DHA group compared with st and ard-DHA ( mean+/-SD , high-DHA 6.8+/-1.2 , st and ard-DHA 5.2+/-0.7 , p<0.0005 ) but AA was lower ( high-DHA 14.9+/-1.3 , st and ard-DHA 16.0+/-1.2 , p<0.0005 ) . Feeding preterm infants human milk and formula with 1 % DHA raises but does not saturate erythrocyte phospholipids with DHA . Milk exceeding 1 % DHA may be required to increase DHA status to levels seen in term infants Objective : The aim of this study was to assess the effects of fish oil supplementation in pregnancy on  maternal erythrocyte fatty acid composition at different stages of pregnancy and in the post-partum period , and on neonatal  erythrocyte fatty acid composition . Design : A double-blind , r and omised , placebo-controlled study . Setting : Subiaco , Western Australia . Subjects : In all , 98 women booked for delivery at St John of God Hospital , Subiaco , were recruited from private rooms of obstetricians . In total , 83 women and their healthy full-term babies completed the study . Interventions : Women received either 4 g of fish oil ( n=52 ) ( 56 % docosahexaenoic acid ( DHA ) and 28 % eicosapentaenoic acid ( EPA ) or placebo ( olive oil ) ( n=46 ) per day from 20 weeks gestation until delivery . Main outcome measures : Erythrocyte phospholipid fatty acids were measured in maternal peripheral blood at 20 , 30 and 37 weeks of pregnancy and at 6 weeks post partum , and from cord blood collected at birth . Results : Compared to the control group , maternal EPA and DHA were significantly higher in the fish oil group at 30 and 37 weeks gestation , and remained elevated at 6 weeks post partum ( P<0.001 ) . The proportions of n-6 polyunsaturated ( arachidonic acid , 22:3n-6 and 22:4n-6 ) were significantly lower in the fish oil supplemented group at the same time periods ( P<0.001 ) . Similarly , the proportions of EPA and DHA were significantly higher ( P<0.001 ) , and those of n-6 polyunsaturated fatty acids arachidonic acid , 20:3n-6 , 22:3n-6 and 22:4n-6 were significantly lower ( P<0.001 ) , in erythrocytes from neonates in the fish oil group , compared to those in the control group . Conclusions : Fish oil supplementation from 20 weeks of pregnancy until birth is an effective means of enhancing n-3 fatty acid status of both mothers and neonates . Furthermore , the changes in maternal erythrocyte fatty acid composition are retained until at least 6 weeks post partum . It is essential to assess the effects of concomitant decreases in arachidonic acid status before any dietary recommendations can be made . Sponsorship : The study was supported by grants from the NH & MRC and Raine Medical Research Foundation , Australia CONTEXT Uncertainty about the benefits of dietary docosahexaenoic acid ( DHA ) for pregnant women and their children exists , despite international recommendations that pregnant women increase their DHA intakes . OBJECTIVE To determine whether increasing DHA during the last half of pregnancy will result in fewer women with high levels of depressive symptoms and enhance the neurodevelopmental outcome of their children . DESIGN , SETTING , AND PARTICIPANTS A double-blind , multicenter , r and omized controlled trial ( DHA to Optimize Mother Infant Outcome [ DOMInO ] trial ) in 5 Australian maternity hospitals of 2399 women who were less than 21 weeks ' gestation with singleton pregnancies and who were recruited between October 31 , 2005 , and January 11 , 2008 . Follow-up of children ( n = 726 ) was completed December 16 , 2009 . INTERVENTION Docosahexaenoic acid-rich fish oil capsules ( providing 800 mg/d of DHA ) or matched vegetable oil capsules without DHA from study entry to birth . MAIN OUTCOME MEASURES High levels of depressive symptoms in mothers as indicated by a score of more than 12 on the Edinburgh Postnatal Depression Scale at 6 weeks or 6 months postpartum . Cognitive and language development in children as assessed by the Bayley Scales of Infant and Toddler Development , Third Edition , at 18 months . RESULTS Of 2399 women enrolled , 96.7 % completed the trial . The percentage of women with high levels of depressive symptoms during the first 6 months postpartum did not differ between the DHA and control groups ( 9.67 % vs 11.19 % ; adjusted relative risk , 0.85 ; 95 % confidence interval [ CI ] , 0.70 - 1.02 ; P = .09 ) . Mean cognitive composite scores ( adjusted mean difference , 0.01 ; 95 % CI , -1.36 to 1.37 ; P = .99 ) and mean language composite scores ( adjusted mean difference , -1.42 ; 95 % CI , -3.07 to 0.22 ; P = .09 ) of children in the DHA group did not differ from children in the control group . CONCLUSION The use of DHA-rich fish oil capsules compared with vegetable oil capsules during pregnancy did not result in lower levels of postpartum depression in mothers or improved cognitive and language development in their offspring during early childhood . TRIAL REGISTRATION anzctr.org.au Identifier : ACTRN12605000569606 OBJECTIVES Docosahexaenoic acid ( DHA ; 22:6 n-3 ) and arachidonic acid ( AA ; 20:4 n-6 ) are important for development of the central nervous system in mammals . There is a growth spurt in the human brain during the last trimester of pregnancy and the first postnatal months , with a large increase in the cerebral content of AA and DHA .  The fetus and the newborn infant depend on maternal supply of DHA and AA . Our hypothesis was that maternal intake of DHA during pregnancy and lactation is marginal and that high intake of this fatty acid would benefit the child . We examined the effect of supplementing pregnant and lactating women with very-long-chain n-3 polyunsaturated fatty acids ( PUFAs ; cod liver oil ) on mental development of the children , compared with maternal supplementation with long-chain n-6 PUFAs ( corn oil ) . METHODS The study was r and omized and double-blinded . Pregnant women were recruited in week 18 of pregnancy to take 10 mL of cod liver oil or corn oil until 3 months after delivery . The cod liver oil contained 1183 mg/10 mL DHA , 803 mg/10 mL eicosapentaenoic acid ( 20:5 n-3 ) , and a total of 2494 mg/10 mL summation operator n-3 PUFAs . The corn oil contained 4747 mg/10 mL linoleic acid ( 18:2 n-6 ) and 92 mg/10 mL alpha-linolenic acid ( 18:3 n-3 ) . The amount of fat-soluble vitamins was identical in the 2 oils ( 117 micro g/mL vitamin A , 1 micro g/mL vitamin D , and 1.4 mg/mL dl-alpha-tocopherol ) . A total of 590 pregnant women were recruited to the study , and 341 mothers took part in the study until giving birth . All infants of these women were scheduled for assessment of cognitive function at 6 and 9 months of age , and 262 complied with the request . As part of the protocol , 135 subjects from this population were invited for intelligence testing  with the Kaufman Assessment Battery for Children ( K-ABC ) at 4 years of age . Of the 135 invited children , 90 came for assessment . Six children did not complete the examination . The K-ABC is a measure of intelligence and achievement design ed for children aged 2.5 years through 12.5 years . This multisubtest battery comprises 4 scales : Sequential Processing , Simultaneous Processing , Achievement ( not used in the present study ) , and Nonverbal Abilities . The Sequential Processing and Simultaneous Processing scales are hypothesized to reflect the child 's style of problem solving and information processing . Scores from these 2 scales are combined to form a Mental Processing Composite , which serves as the measure of intelligence in the K-ABC . RESULTS We received dietary information from 76 infants ( 41 in the cod liver oil group and 35 in the corn oil group ) , documenting that all of them were breastfed at 3 months of age . Children who were born to mothers who had taken cod liver oil ( n = 48 ) during pregnancy and lactation scored higher on the Mental Processing Composite of the K-ABC at 4 years of age as compared with children whose mothers had taken  corn oil  ( n = 36 ; 106.4 [ 7.4 ] vs 102.3 [ 11.3 ] ) . The Mental Processing Composite score correlated significantly with head circumference at birth ( r = 0.23 ) , but no relation was found with birth weight or gestational length . The children 's mental processing scores at 4 years of age correlated significantly with maternal intake of DHA and eicosapentaenoic acid during pregnancy . In a multiple regression model , maternal intake of DHA during pregnancy was the only variable of statistical significance for the children 's mental processing scores at 4 years of age . CONCLUSION Maternal intake of very-long-chain n-3 PUFAs during pregnancy and lactation may be favorable for later mental development of children Background Breast milk contains many immunomodulatory factors ( soluble CD14 ( sCD14 ) , IgA and cytokines ) with the potential to influence infant immune development Objective : We investigated how cod liver oil influences the amount of essential fatty acids in mothers ’ breast milk . Design and Intervention : Lactating mothers ( n=22 ) were r and omized into four groups 3–8 weeks after parturition . They were supplemented for 14 days with 0 , 2.5 , 5 and 10 ml cod liver oil ( 7.7 g eicosapentaenoic acid ( EPA , 20:5n-3 ) , 10.2 g docosahexaenoic acid ( DHA , 22:6n-3 ) and 22.9 g n-3 fatty acids in total per 100 ml ) . Results : In maternal plasma phospholipids there was an increase in the content of EPA and
