[Biological developmental parameters in newborns in Silesia born between the 30th and 42nd week of pregnancy]

On the basis of anthropometric data from 2985 newborns in Silesia, percentile grids were constructed of birth weight, height, head circumference, and chest circumference for boys, girls, and both sexes jointly. It was found that these parameters, especially in premature babies, were lower in comparison to those accepted for the whole country.
