[Mathematic formulation of weight/height somatograms of Hellbrügge and Vogt (1961) and comparison with data of Maaser (1971)].

The height/weight relations as given by Hellbrügge and Vogt (1961) are brought into a mathematical formulation following the procedure already applied by the author to the Maaser tables of 1974 (Sager 1981 a). To this purpose the quasilinear behaviour of log weight to height from 100 cm upward as similarly used by Krüger (1975) is complemented by a function thus incorporating the values from birth to about 2 years of age and correcting the relation thereafter. Nonlinear regressions are exercised and compared with the results from the dates of Maaser (1974) showing close agreement in the first years of life and small but increasing deviations for the weight from 5 (female) or 8 to 9 (male) years respectively.
