“…As a group, the birth weights were appropriate for gestational age (51 % of the weights lay above the mean for gestational age [21] and the mean systolic and diastolic blood pressures were similar to those reported previously, giv en that the sample had a mean birth weight of 1.69 kg [22]. The mean systolic blood pressure rose with increasing birth weight, gestational age and postnatal age as has previously been described [19,[23][24][25].…”

Atrial Natriuretic Peptide in the Preterm Newborn

Atrial natriuretic peptide (ANP), plasma renin and renin substrate concentrations (PRC and PRS) were measured in 31 preterm infants with idiopathic respiratory distress syndrome. Infants were studied at a mean of 1.4 days; 17 infants were also studied 2 days later. A 6-hour urine collection was made from 13 male infants on the first day of sampling to assess renal function. Both ANP and PRC were elevated and showed wide ranges of values (geometric means of 620 pg/ml and 18.4 ng/ ml/h). Plasma ANP was significantly correlated with pH, PaCO₂ and base excess. No correlations with parameters of cardiovascular or renal function were found. Plasma ANP rose in 13 of the 17 paired samples. We suggest that the very high ANP concentrations in these babies are a consequence of the pulmonary haemodynamic disturbances which accompany respiratory distress in the newborn.

“…The birthweight, length and head circumference of each baby were expressed as standard deviation scores for gestation based on reference data in order to separate the outcome measures of gestational age and quality of intrauterine growth. The data published by Babson (1970) were used as reference data for length and head circumference, but for birthweight we used data from Keen and Pearse (1985) which used data based on clinical gestational assessment rather than menstrual history.…”

Ethnic and environmental factors affecting fetal growth in Papua New Guinea

We studied 738 live singleton births in Papua New Guinea to examine the contribution of ethnic origin and environmental factors to birth weight and gestation. Maternal history, examination and post-partum anthropometry, infant anthropometry and clinical gestational assessment were performed, and placental blood slides and histology were examined. Mothers from Highlands provinces who delivered on the coast had larger babies (mean birthweight 3.34 SD 0.48 kg) than either indigenous coastal mothers (mean 3.10 SD 0.51 kg) or those migrating to Port Moresby from other coastal regions (mean 3.14 SD 0.51 kg). This was due to a combination of longer gestation and better intrauterine growth (assessed by birthweight standard deviation scores). Gestation was slightly longer in Highlands mothers delivering on the coast compared with those delivering in the Highlands, but birthweight standard deviation scores were unchanged. Malarial infection of the placenta was almost never found. Stepwise regression analysis showed that parity, maternal height, Highlands origin and maternal body mass index (weight/height2) were all significant predictors of birthweight standard deviation score, while maternal body mass index and Highlands origin were predictors of gestational length. We conclude that Highland mothers have a tendency to deliver heavier babies, and do not demonstrate the fetal growth-retarding effects of altitude seen in other races. Although the incidence of low birthweight was only 7.1% in our study, we found that indices of maternal nutrition were predictors of birth weight.

“…It is a well known concept to child health workers. The prevalence varies, but in some communities has been reported to be as high as 5 [15][16][17][18][19][20][21][22][23][24][25][26][27]) and the mean difference in ages of the two groups of children at the time of measurement was four days. The difference between the mean birth weight and gestation of the children who failed to thrive (3343 g, 39-4 weeks) and those of the control children (3355 g, 39-6 weeks) was not significant.…”

The maximum weight centile achieved by a child between 4 and 8 weeks of age was found to be a better predictor of the centile at 12 months than the birth weight centile. Children whose weight deviated two or more major centiles below this maximum weight centile for a month or more showed significant anthropometric differences during the second year of life from those who showed no such deviation. It is suggested that this leads to a logical and practical definition of failure to thrive.

Birthweight between 14 and 42 weeks' gestation.

Abstract: The mean weights of the sample differ considerably from those of the Gairdner and Pearson chart which are, therefore, considered to be inappropriate for the Sheffield population.
