[Body proportions of healthy and short stature adolescent girls].

INTRODUCTION

Regularly conducted assessment of body proportions is of importance as early detection of possible growth disorders and immediate prevention may allow gathering an optimum of child's genetically conditioned level of development.

AIM OF THE STUDY

To assess body proportions of adolescent girls, healthy or with growth deficiency.

MATERIAL AND METHODS

Three groups were studied: 104 healthy, short-statured girls (body height below the 10th percentile), 84 girls with Turner's syndrome (ZT) and 263 healthy girls of normal stature (between percentiles 25 and 75), all aged 11-15 years. The following measurements were conducted according to common anthropometric standards: body height, sitting body height, shoulder width, upper extremity length and lower extremity length - the last one was computed as the difference between standing and sitting body heights. All measurements were converted to logarithms and allometric linear regressions vs log body height were computed.

RESULTS

The Turner girls proved to have allometrically shorter legs (p<0.001) and wider shoulders (p<0.001) compared with both groups of healthy girls, and longer upper extremities (p<0.001) compared with the girls of normal stature. Healthy, short-statured girls had longer lower extremities (p<0.001) as compared to other groups; they also had wider shoulders (p<0.001) and longer upper extremities (p<0.001) compared to healthy girls of normal height.

CONCLUSIONS

Allometric relations of anthropometric measurements enable a deeper insight into the body proportions, especially in the growth period. The presented discrimination of Turner girls may serve as a screening test, and recommendation for further clinical treatment.
