title: [Influence of the distribution of body fat on vascular risk].
abstract: The metabolic and cardiovascular complications of obesity are dependent upon the distribution of body fat excess: predominantly abdominal or "android" obesity is more pathogenic than "gynoid" obesity which predominates in the lower part of the body. Adipose tissue overloads localized to the abdomen are associated with hypermortality from vascular diseases, even in patients who are not overweight. The metabolic characteristics of abdominal adipocytes, which have increased lipolytic capacity, might account for this situation, as they would facilitate hyperinsulinism, insulin resistance and such-metabolic disturbances as arterial hypertension, diabetes mellitus and dyslipidemia. Androgens seem to play a key role in the development of obesity morphotypes. These notions have important practical applications: an excess of body fat is not necessarily pathogenic; as regards vascular and metabolic risks, body fat distribution seems to be more important than overweight.
