Introduction

Eating disorders are psychiatric conditions of clinical significance. Over the past several decades, knowledge in the field of eating disorders has expanded exponentially in domains of etiology, clinical presentation, prevention, and treatment. The primary adult eating disorder diagnoses are anorexia nervosa, bulimia nervosa, and binge eating disorder. Initially thought of as disorders affecting only upper-class Caucasian females, the literature now increasingly recognizes the impact of eating disorders on boys and men, and on individuals from a range of cultures and ethnicities. Although eating disorders remain more common among females, examining differences in eating disorder presentation across sex and other demographic features has been an important research undertaking in recent years. Although relatively rare, eating disorders are distinct from many psychiatric conditions in their frequent involvement of medical comorbidities. As such, their care typically requires a multidisciplinary approach, including providers from both psychological health and medical fields. Despite the development of effective psychological treatments (e.g., cognitive-behavioral therapy, interpersonal psychotherapy, family-based behavioral therapy), full recovery remains elusive for many individuals with eating disorders. Therefore, early detection and prevention may be the most effective strategies for reducing the individual and societal burden of eating disorders. To date, the majority of systematic research has been conducted within the three primary eating disorder diagnoses. However, there is wide variety to the presentation of disordered eating, and the default “eating disorder not otherwise specified” (EDNOS) category contains the highest proportion of patients seen in clinical practice. Indeed, with controlled empirical studies often excluding patients with EDNOS, current knowledge regarding the etiology and treatment of this most prevalent eating disorder category remains lacking. This is particularly troubling when considering that over half of patients presenting for clinical care receive a diagnosis of EDNOS. Accordingly, the diagnosis and classification of eating disorders has been a focus of much research attention, particularly with the development and publication of the most recent edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Similarly, the classification of eating disorders in children has been a topic of much attention and debate. Of note, this article includes studies on eating disorders (as defined by the DSM criteria) rather than the full spectrum of disordered eating behaviors commonly reported by youth and adults, and it does not cover other eating/feeding disorders that occur during early childhood, such as pica, or the new diagnosis of avoidant/restrictive food intake disorder. References are categorized not by disorder, but rather by topic—beginning with general overviews and eating disorder organizations, followed by eating disorder prevalence rates, etiology, diagnosis and assessment, comorbidities, course, and treatment and prevention.

General Overviews and Textbooks

The focus of this section is on broad overviews of eating disorders. The majority of works presented are books, including those that could be used as course textbooks for students, particularly at a graduate level, such as Agras 2010. Alexander, et al. 2013 is a useful text for clinicians or researchers specializing in or wanting to learn more about binge eating disorder, the newest disorder to be recognized as a formal eating disorder diagnosis. Tanofsky-Kraff, et al. 2013 is a more brief discussion of the most recent research in the area of binge eating disorder. Two books—Birmingham and Treasure 2010 and Fairburn and Brownell 2005—examine the additional topics of medical management and obesity, respectively. Birmingham and Treasure 2010 is a practical primer of medical considerations for those treating eating disorders. Fairburn and Brownell 2005 contains many brief overviews relevant to eating disorders and obesity; in addition to their general use by clinicians and researchers, these chapters could also be used for didactic purposes (e.g., course readings). Some of the chapters within these books are cited elsewhere in this article, as they are thorough and highly useful resources, covering a range of topics (e.g., diagnosis and assessment, etiology, and treatment of eating disorders). Alexander and Treasure 2011 is another comprehensive text, with a particular focus on the collaborative, multidisciplinary treatment of eating disorders. For a stand-alone brief overview, Treasure, et al. 2010 is valuable for readers wanting a broad yet concise review of eating disorders. Additionally, one important diagnostic and clinical issue that has faced those who research and treat eating disorders is the broad category of eating disorder not otherwise specified (EDNOS), which describes at least half of patients seen in clinical care. This pattern, along with a detailed examination of patients who fall into this category, is covered in Fairburn, et al. 2007. Among texts published in recent years that provide broad coverage of multiple issues in eating disorders, relatively few specifically focus on pediatric populations. Le Grange and Lock 2011 and Lask and Bryant-Waugh 2013 stand out as important resources for the identification and treatment of eating disorders in children and adolescents. For more brief overviews, Treasure, et al. 2010 is included in this section as well. Treasure, et al. 2010 provides an update to the originally published review by Fairburn and Harrison (“Eating Disorders,” Lancet 361.9355 [2003]: 407–416), and both articles are valuable for readers wanting a broad yet concise review of eating disorders.
