[The interpretation of morphometric data of 10- to 13-year-old school children from the survey year 1978 of the Braunschweig Longitudinal Study].
The paper represents a cross-sectional study from a sample of 1800 out of 3000 school-children from the Braunschweiger Längsschnitt. In this methodical approach we first eliminate approximately the influence of age and stature on the raw data from all body measurements with regression equations. The transformed data were attached to three "types" named 'below normal', 'normal', and 'above normal', in course of which 'normal' means all cases in the range of the standard deviation, whereas the two other "types" are corresponding to the adjacent ranges of values. Subsequently each transformation on the mean of age and stature a discriminant analysis has been performed grouping the cases by the "types" of the width of pelvis, resp. shoulders. There were found great influences of the stature on the chosen measures of width in our investigated class of age. They could be made clear alone by using allometrical methods. Only before correction of the body height the given grouping is supported by other variables, at which different sets of variables dominate the discriminant functions for boys and girls. Out of this new aspects and considerations result for the understanding of the physique and the physique typologies, which would be significant in our opinion for acceleration phenomenon as well as for the comparative examinations on populations.
