Media type: E-Article Title: 5‐HTTLPR moderates the relation between changes in depressive and bulimic symptoms in adolescent girls: A longitudinal study Contributor: Mata, Jutta; Gotlib, Ian H. imprint: Wiley, 2011 Published in: International Journal of Eating Disorders Language: English DOI: 10.1002/eat.20850 ISSN: 0276-3478; 1098-108X Keywords: Psychiatry and Mental health Origination: Footnote: Description: <jats:title>Abstract</jats:title><jats:sec><jats:title>Objective</jats:title><jats:p>Depression and bulimia both are associated with low serotonin levels.

Few studies, however, considered the possible role of serotonin linking both disorders. Gaining a better understanding of developmental effects of low serotonin could help to identify high‐risk individuals and provide effective prevention and intervention. © 2010 by Wiley Periodicals, Inc.
