- Background: The requirement of essential fatty acids (EFA) for the development of the brain is well documented. Objective: To investigate the early neurological development at term and 44 weeks gestational age in preterm infants in relation to EFA concentrations in breast milk and in infants' and mothers' plasma phospholipids. Method: Fifty-one premature infants and their mothers were consecutively included in the study. The median gestational age was 34 weeks (range 24–36). The motor quality, motor and behavioural development were assessed by General Movements (GMs), the Brazelton Neonatal Behavioral Assessment Scale (BNBAS) and a Self Regulation Scale. Results: Mother's education and gestational age correlated to several outcome variables. Multiple regression with correction for background factors showed negative associations between early breast milk concentrations of Mead acid and GMs and between AA and the BNBAS clusters Orientation and Range of States, respectively. Between 40 and 44 weeks gestational age, no expected increased scores were observed for Regulation of States, Range of States and Self Regulation. During the corresponding time, increased concentration of linoleic acid in mothers' plasma was negatively associated with improvement in Orientation and increased concentration of EPA in the infants' plasma was positively associated with improvement in Autonomic Stability. Conclusions: The major omega-6 fatty acids and Mead acid were negatively associated with early development and omega-3 fatty acids positively associated. Mother's education and the gestational age influenced the outcome more strongly than mother's and infant's morbidities. Further follow-up will elucidate the significance of these early findings.

- Aim: To assess the development of preterm infants from 40 weeks gestational age to 18 months corrected age in order to identify early predictors of later development. Methods: Fifty-one infants were involved. Infant development was assessed at 40 and 44 weeks gestational age with the Brazelton Neonatal Behavioral Assessment Scale and a Self-Regulation Scale and at 3, 6, 10, 18 months corrected age with the Bayley Scales of Infant Development. The quality of general movements was assessed at 1 and 3 months corrected age and maternal attachment style at infant's age of 6 months corrected age with the Relation Scale Questionnaire. Results: At term age and 1 month corrected age, preterm infants were less mature and had lower levels of self-regulation than full-term infants. At 3 months corrected age, a higher proportion of preterm infants (43%) had mildly abnormal motor quality compared to the general population (25%). At all follow-ups, preterm infants had delayed mental, motor, and behavioral development, which was associated with the level of self-regulation, motor quality, and maternal attachment style. Maternal education level was the most predominant background factor related to infant development. Conclusion: Preterm infants show early-in-life deviations in self-regulation, motor quality, and development. These deviations are risk factors for later optimal functioning.

- BACKGROUND: The supply of long-chain polyunsaturated fatty acids via the placenta is interrupted in premature infants, making them exclusively dependent on breast milk, which varies in fatty acid (FA) concentrations depending on the mother's diet. OBJECTIVE: To in a longitudinal study explore the relation between FA status in mothers and infants from an unselected cohort of prematures, not requiring intensive care. DESIGN: Breast milk and mothers' and infants' plasma phospholipid FA concentrations from birth to 44 weeks of gestational age were analysed and compared with mothers' food intake, assessed using a 3-day diary. Fatty acids were analysed by capillary gas-liquid chromatography. RESULTS: The energy intake was low in 75% of mothers, and 90% had low intake of essential FAs (EFAs). Dietary linoleic acid (LA, 18:2w6), but not w3 FAs, correlated to concentrations in breast milk. Infants' plasma and breast milk correlated for arachidonic (AA, 20:4w6), eicosapentaenoic (EPA, 20:5w3) and docosahexaenoic (DHA, 22:6w3) acids. A high concentration of mead acid (20:3w9) in the infants at birth correlated negatively to the concentrations of LA, AA and w3 FAs. Infants of mothers who stopped breastfeeding during the study period showed decreased DHA concentrations and increased w6/w3 ratios, with the opposite FA pattern seen in the mothers' plasma. CONCLUSION: Although dietary w3 FAs were insufficient in an unselected cohort of mothers of premature infants, breastfeeding resulted in increased levels of DHA in the premature infants at the expense of the mothers, suggesting a general need to increase dietary w3 FAs during pregnancy and lactation.

- The objective of this study was to investigate any association between infants' early development and PUFA concentrations in early breast milk and infants' plasma phospholipids at 44 weeks gestational age. Fifty-one premature infants were included. The quality of general movement was assessed at 3 months, and motor, mental and behavioral development at 3, 6, 10 and 18 months corrected age using Bayley's Scales of Infant Development (BSID-II). Linoleic acid, the major n-6/n-3 FA ratios, Mead acid and the EFA deficiency index in early breast milk were negatively associated with development up to 18 months of age. DHA and AA, respectively, in infants' plasma phospholipids was positively, but the AA/DHA ratio negatively, associated with development from 6 to 18 months of age. Our data suggest that the commonly found high n-6 concentration in breast milk is associated with less favorable motor, mental and behavioral development up to 18 months of age.

- Myelination is important perinatally and highly dependent on long-chain saturated and monounsaturated fatty acids. Long-chain polyunsaturated fatty acids, nowadays often supplemented, inhibit oleic acid synthesis. Using data from a premature cohort, we studied if nervonic, lignoceric and oleic acids correlated to growth and early development up to 18 months corrected age. Small for gestational age infants had lower concentrations than infants appropriate for gestational age. Only oleic acid was negatively correlated to long-chain polyunsaturated fatty acids. Oleic and lignoceric acids correlated to social interaction at one month, and nervonic acid to mental, psychomotor and behavioral development at 6, 10 and 18 months, also when adjusted for several confounders. Negative association between oleic acid and long-chain polyunsaturated fatty acids suggests inhibition of delta-9 desaturase, and nervonic acid´s divergent correlation to lignoceric and oleic acids suggests different metabolism in neonatal period. Our results may have implications for the supplementation of premature infants.
