To our knowledge, this is the first study to demonstrate
that disordered eating in adolescence implies a high risk for
future depression. In accordance with previous studies, we
also found a relationship between specific phenomena such
as loss of control of eating, purging behaviour, and body
distortion, in youth with later depression [41, 42], independent
of prior body weight and baseline depressive
symptoms. Eating-disordered behaviour likely reflects high
dissatisfaction with oneself and ‘‘the undue influence of
body weight or shape on self-esteem’’ (DSM-5, [43]), both
of which may contribute to the development of depression.
