Objectif. Les associations entre l’image corporelle et l’indice de masse corporelle (IMC) en comparaison avec la composition corporelle chez des adultes en excès de poids, obèses et ayant un poids santé ont été étudiées.

Methods: Weight and height were determined, and the percentage of fat mass (%FM) and percentage of fat-free mass (%FFM) were measured by dual energy X-ray absorptiometry in 75 male and 87 female young adults (21.1 ± 1.9 years; 25.2 ± 4.4 kg/m2 [mean ± standard deviation]). Body image was measured using the three subscales Weight Esteem, Appearance Esteem, and External Attribution of the Body-Esteem Scale for Adolescents and Adults (BESAA).
