Long-chain polyunsaturated fatty acid status and early growth of low birth weight infants

We correlated arachidonic acid (AA) and docosahexaenoic acid (DHA) status with anthropometric measures and growth rates in a group of low birth weight infants (≤2500 g; gestational ages 30–41 weeks; n = 143). AA and DHA status were measured in erythrocytes (RBC) and plasma cholesterol esters (CE) during days 10 to 42. Infants received preterm formula without long-chain polyunsaturated fatty acids (LCP; n = 81), with LCP (n = 29) or maternal milk (n = 33). RBC AA contents on day 10 were correlated (P < 0.05) with birth weight in breast-fed infants and all formula-fed infants, with on day 10 a standard deviation score (SDS) for weight, length and occipito-frontal circumference in all formula-fed infants, and with on day 10 an SDS for length in breast-fed infants. Brain weight was related to RBC DHA and CE DHA contents on both day 10 and day 42 in formula-fed infants. Of the variances of brain growth parameters on day 42, 21–34% were explained by DHA status on day 42 and protein intake from days 10–42. Conclusion We conclude that parameters of early neonatal AA status are related to intra-uterine rather than to post-natal growth. Parameters of post-natal brain growth are related to RBC DHA and CE DHA contents on day 42, and to dietary protein intake. These results point to the importance of dietary DHA for brain growth in the first 6 post-natal weeks. Received: 23 July 1996 / Received in revised form and accepted: 18 June 1997     

Fatty acid balance studies in term infants fed formula milk containing long-chain polyunsaturated fatty acids

Long-chain polyunsaturated fatty acids (LCP) are thought to be required for optimal nervous system development in the newborn. A commercial milk formula containing LCP (Aptamil-LCP) with a fatty acid profile closely resembling breast milk, has recently been introduced for term infants. The absorption of fatty acids in term infants was examined in a double-blind randomized controlled trial comparing Aptamil-LCP ( n = 20) and standard Aptamil ( n = 20). Formula-fed newborn infants were studied from birth for 14 d. Fat balances (3 d) were performed from d 10. A 3-d stool collection was performed from d 10 in a parallel breastfed group ( n = 21). Plasma samples were taken on d 6. Median fat excretion (mg kg⁻¹) was 897.1, 615.0 and 355.2 with Aptamil, Aptamil-LCP and breastfeeding, respectively. The median total fat absorption coefficient in Aptamil-LCP-fed infants was higher than in those fed standard Aptamil ( p < 0:01). These findings were accounted for by differences in the excretion and absorption of long-chain saturated fatty acids (C14:0, C16:0 and C18:0). Higher fat excretion was associated with bulkier and firmer stools. Only trace amounts of LCP were detected in the stools of all groups. This accounted for less than 4% of dietary intake in Aptamil-LCP-fed infants. No differences in the utilization of LCP from Aptamil-LCP and breast milk feeding were apparent. Plasma phospholipid fatty acid composition data reflected differences in dietary LCP intake. Thus, PL LCP levels were highest in the breastfed infants and lowest in the Aptamil-fed infants, with values for the Aptamil-LCP-fed group falling in between.
