In order to determine the differences between anthropometric characteristics and postural disorders of schoolchildren aged 12, a study was carried out which encompassed two generations of schoolchildren, on a sample of 299 boys and girls, measured during the 1987 and 2002 school years. In order to determine the differences between the anthropometric area and the postural status of two different generations of schoolchildren, a canonical discriminant analysis was used. The anthropometric area was defined by 10 measurements, which covered the longitudinal and circular dimensionality of the skeleton and fatty tissue below the epidermis, while postural status was evaluated by two variables, defined as bad posture due to scoliosis and flat feet. The results of the study indicate significant differences between the schoolchildren belonging to the two generations, which are especially visible in the measurements of the longitudinal dimensionality of the skeleton, and which are significantly greater for the children of the 1987 generation, as well as in circular dimensionality and fatty tissue below the epidermis, which are greater for the children of the 2002 generation. Significant differences were not noted in the area of postural disorders, but an informative difference was visible for bad posture due to scoliosis, which was more pronounced in the children belonging to the 2002 generation. .
