UNLABELLED: We correlated arachidonic acid (AA) and docosahexaenoic acid (DHA) status with anthropometric measures and growth rates in a group of low birth weight infants (< or = 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.
OBJECTIVE: Our goal was to identify prenatally available parameters that correlate with neonatal outcome and could be used for predicting such outcome in the extremely low-birth-weight pregnancy. STUDY DESIGN: From 1990 through 1995, obstetric and neonatal data of live-born nonanomalous singleton infants with birth weights between 400 and 1000 gm were reviewed. Only cases in which ultrasonographic biometry, including biparietal diameter, abdominal circumference, and femur length, was performed < or =3 days before delivery were included. Overall survival (defined as alive at discharge) and survival without specific severe neonatal morbidities (namely, retinopathy of prematurity [stage 3 or 4], intraventricular hemorrhage [grade 3 or 4], periventricular leukomalacia, chronic lung disease, and deafness) were ascertained. The best combination of prenatal parameters for the prediction of overall survival and survival without severe morbidity was determined by backward stepwise logistic regression analyses. RESULTS: The most significant prenatal predictors of overall survival were the obstetric estimate of gestational age and the abdominal circumference (chi2 = 11.8036, p = 0.0006 and chi2 = 8.1862, p < 0.005, respectively). Survival without severe morbidity was also predicted by the same combination of parameters (chi2 = 21.9079, p = 0.0001 and chi2 = 6.538, p = 0.01, respectively). The estimated fetal weight was not a significant independent predictor of either category of outcome (chi2 = 0.1249, p = 0.72 and chi2 = 0.0361, p = 0.85, respectively). On the basis of the regression formulas, curves displaying the probabilities of overall survival and survival without severe morbidity with any combination of gestational age and abdominal circumference were developed. CONCLUSION: The combination of gestational age and the abdominal circumference measurements appears to be superior to any combination that included estimated fetal weight data for predicting neonatal outcome in the neonates weighing < or =1000 gm. We developed a mechanism for predicting neonatal outcome in this weight category on the basis of prenatally available parameters. This information could prove useful for both parental counseling and obstetric decision making.
