Serial Investigation on the Interrelationship between Body Height, Weight and Selected Craniofacial Dimensions During Mixed Dentition Period

The interrelationships between growth rates (and size) of the selected cranifacial dimensions and body dimensions (hight and weight) were investigated in the longitudinal data of primary school children from 6 to 11 years of age. The data were obtained from serial cephalometric radiographs and health record which were taken at one year interval. Regression analyses were used to analyze the data. The main concludions might be summarized as follows: 1. Size relationshios between body height (and weigh) and S-Gn, posterior facial height(S-Go), total body height, weight and anterior cranial base length(S-N). 2. Correlation coefficients between facial dimensions and body height (and weight) were getting lower with age increase. 3. At age groups, significant prediction equation for some facial dimensions with body height and weight were obtained. 4. In this sample, the growth rates of facial dimensions and body height and weight showed almostly constant during this age period and the growth rate of body height and weight of grils was exceeded that of boys. 5. A relatively high degree of variation between indiciduals existed in the sample. 6. A positive correlation was found for the relationship between the growth rates of facial dimensions and those of body height (and weight) in body and grils, but was not found in total samples.
