Paper Abstract

The product of the ob-gene named leptin is correlated with body fat mass in humans. Little evidence exists if the same holds true for body fat distribution. In this study we therefore investigated plasma leptin levels and the subcutaneous adipose tissue topography (SAT-Top) by means of the newly developed optical device Lipometer before and after a 3 week weight reduction camp. Thirty four obese boys (mean age 12a) took part in this study. Body fat distribution were assessed by means of Lipometer to measure the thickness of a subcutaneous fat layer at 15 standardized body sites (SAT- Top). Plasma leptin levels (LL) were measured by radioimmunoassay. All measurements were taken at the beginning and at the end of the camp. By dividing all boys according chronological age (group A: age less than 12a, n equals 17/group B: greater than 12a, n equals 17) we found correlations with the combination of measured body sites (MBS) before (A: MBS vs. LL, R2 equals 0.79; p less than 0.01/B: MBS vs. LL, R2 equals 0.35; n.s.) and after (A: MBS vs. LL, R2 equals 0.83; p less than 0.01/B: MBS vs. LL, R2 equals 0.70; p less than 0.01) the intervention. Our study confirms that the subcutaneous adipose tissue topography (SAT- Top) by means of the optical device Lipometer serves as a marker of plasma leptin levels in obese boys and highlights the use of this optical device in a predictive manner.
