Serum leptin and insulin concentrations in prepubertal lean, obese and insulin‐dependent diabetes mellitus children

Abstract

The elevated concentration of leptin in insulin-dependent diabetic children, independent of body mass index, was probably caused by chronically increased serum insulin levels. We demonstrated that not only body mass index but also insulin was a significant independent predictor of serum leptin concentrations. It is therefore suggested that insulin might play an important role in regulating serum leptin concentrations independent of adiposity.
