[Analysis of a 1992 birth sample in Germany. 1: New percentile values of the body weight of newborn infants].

14 of the 16 German Federal "Lands" ("Bundesländer") participated in the first assessment in perinatal medicine in reunited Germany. A total of stored data representing 563,480 single births were used to calculate percentile values for birth weight, size (length) at birth and circumference of the head from the 23rd week of pregnancy, presented in tabulated and graphic form. Only data of German Population were evaluated; no other selective criteria were applied. The percentile values were calculated via the cumulative frequencies. Besides the conventional somatic data, the length-related birth weight percentile values were also stated, since these enable a classification more in accordance with the fetal development of the newborn. A cursory comparison with other German standard value determinations and with Lubchenco's curve is carried out.
