Changes in birth weight, birth length and head circumference of Hungarian children in the county Baranya between 1968 and 1979-1981.

Possible secular changes of newborn's body measurements were investigated in a cross-sectional growth study in the County Baranya (South Hungary) in 1979-1981. The total sample includes 2,130 children. The results were compared with those obtained by Fekete et al.

Intrauterine weight retardation and the concomitant length retardation: a statistical analysis of anthropometric data.

In 237 low birth weight for gestational age term infants (birth weight less than or equal to 10th percentile; gestational age less than or equal to 37 wk) percentage deviations of birth weight and crown-heel length for gestational age were correlated (a) in a series of linear regressions of three subsequent groups formed according to the magnitude of weight retardation (b) in the pooled material by non-liner regression. Linear regressions yielded equivocal results as to the existence of concomitant length retardation (no correlation in group 1, significant correlation in group 2 and 3). The significant non-linear correlation (i = 0.

Neonatal anthropometry: its value in the assessment of nutritional status and neonatal blood glucose homeostasis.

The use and application of neonatal anthropometry in newborns with different body measurements and nutritional evaluation status is reviewed. The neonatal blood glucose level has been used as a model in testing the predictive value of various indices of body size for the capacity of neonatal blood glucose homeostasis. For example, combining weight and length deficit from the expected means for gestational age and relative body measurements such as weight for length and ponderal index not only convey information about the type and magnitude of growth impairment, but are also good predictors of the risk of hypoglycaemia within the different anthropometric groups of growth retarded infants.

Body size and neonatal hypoglycemia in intrauterine growth retardation.

The relationship between blood glucose and body physique of 233 (42 hypo-and 191 normologycemic) intrauterine growth-retarded neonates was analyzed using different body measurements and indices of body proportions. Classification by combination of weight and length deficit for fetal age revealed that the disproportionately retarded infants (deficit in weight for age > 30%; deficit in length for age less than equal to 15%) were particularly prone to hypoglycemia. The lowest incidence of hypoglycemia was observed in the group with severe proportionate retardation (weight deficit for age > 30%; length deficit for age > 15%).

The redistribution of cardiac output on cold exposure in new-born rabbits.
