In an evaluation of more than 1.8 million datasets taken from the German Perinatal Census in the years 1995-1997, the way in which the classification of somatic fetal development based on gestational age was carried out using different weight-based body mass indices was analyzed. Birth weight (g), birth weight/length ratio (g/cm), body mass index (kg/m(2)) and the Rohrer index (kg/m(3)) were compared. It could be demonstrated that the birth weight/length ratio was the most suitable index to differentiate between hypotrophic and hypertrophic neonates and between genetically small and genetically tall children (an important differentiation in obstetrics).     «
