The importance of body composition measurements to elucidate the dynamics of related diseases in pediatrics is gaining

recognition. The methods used should not expose subjects to high doses of radiation and require substantial cooperation.

The Lipometer is a new optical device that enables the non-invasive, quick and safe determination of the thickness

of subcutaneous adipose tissue SAT layers in mm at any site of the human body. The topographic specification of 15

evenly distributed body sites, which makes it possible to precisely measure subcutaneous body fat distribution, is called

subcutaneous adipose tissue topography SAT-Top. SAT-Top was determined in more than 1000 children and young

adults between the ages of 7 and 21. In this paper we describe the SAT-Top development of these subjects through different

age groups and the differences between male and female SAT-Top development in each age group. SAT layer profiles

medians of the 15 body sites for boys and girls in age group 1 7–9 yrs show a very similar pattern for both sexes, followed

by slightly decreasing SAT layer thicknesses in boys and increasing values in girls in the subsequent age groups.

Between age group 3 11–13 yrs and age group 7 19–21 yrs male and female SAT-Top is significantly different. The

discriminating power between male and female SAT-Top was investigated by stepwise discriminant analysis, which provided

no significant results for age group 1 7–9 yrs, about 73% correct classification for age group 2 9–11 yrs and 3

11–13 yrs, 83% for age group 4 13–15 yrs, and about 91–93% for the following age groups 15–21 yrs.It is known that

SAT development is the same in both sexes until puberty, when girls gain relatively more fat mass than boys to reach a

higher body-fat percentage as adults. This paper presents a precise description of SAT development in boys and girls

from childhood to adolescence, which provides a basis for further investigations.
