title: Binge eating in obese adolescents: an evolutionary concept analysis.
abstract: OBJECTIVE
  The purpose of this paper is to provide an analysis of the concept of binge eating in obese adolescents.
  
  
  METHODS
  Rodgers' evolutionary approach was used to frame this analysis. A search was conducted within the Cumulative Index to Nursing and Allied Health Literature, Medline, and PsycINFO for publications between 1980 and 2011.
  
  
  RESULTS
  Conceptual shifts in the meaning of binge eating have occurred over the past 30 years, yet the two enduring attributes are consumption of a large amount of food and a loss of control over eating.
  
  
  CONCLUSIONS
  Though this analysis demonstrates a consensus concerning the core attributes of binge eating, further refinement of the nuances, subtleties, and use of the concept in relation to adolescents is needed.
