Eating disorders are relatively rare among the general population. This review discusses the literature on the incidence, prevalence and mortality rates of eating disorders. We searched online ...Medline/Pubmed, Embase and PsycINFO databases for articles published in English using several keyterms relating to eating disorders and epidemiology. Anorexia nervosa is relatively common among young women. While the overall incidence rate remained stable over the past decades, there has been an increase in the high risk-group of 15–19 year old girls. It is unclear whether this reflects earlier detection of anorexia nervosa cases or an earlier age at onset. The occurrence of bulimia nervosa might have decreased since the early nineties of the last century. All eating disorders have an elevated mortality risk; anorexia nervosa the most striking. Compared with the other eating disorders, binge eating disorder is more common among males and older individuals.
We examined prevalence, incidence, impairment, duration, and course for the proposed DSM-5 eating disorders in a community sample of 496 adolescent females who completed annual diagnostic interviews ...over 8 years. Lifetime prevalence by age 20 was 0.8% for anorexia nervosa (AN), 2.6% for bulimia nervosa (BN), 3.0% for binge eating disorder (BED), 2.8% for atypical AN, 4.4% for subthreshold BN, 3.6% for subthreshold BED, 3.4% for purging disorder (PD), and combined prevalence of 13.1% (5.2% had AN, BN, or BED; 11.5% had feeding and eating disorders not elsewhere classified; FED-NEC). Peak onset age was 19-20 for AN, 16-20 for BN, and 18-20 for BED, PD, and FED-NEC. Youth with these eating disorders typically reported greater functional impairment, distress, suicidality, mental health treatment, and unhealthy body mass index, though effect sizes were relatively smaller for atypical AN, subthreshold BN, and PD. Average episode duration in months ranged from 2.9 for BN to 11.2 for atypical AN. One-year remission rates ranged from 71% for atypical AN to 100% for BN, subthreshold BN, and BED. Recurrence rates ranged from 6% for PD to 33% for BED and subthrehold BED. Diagnostic progression from subthreshold to threshold eating disorders was higher for BN and BED (32% and 28%) than for AN (0%), suggesting some sort of escalation mechanism for binge eating. Diagnostic crossover was greatest from BED to BN. Results imply that the new DSM-5 eating disorder criteria capture clinically significant psychopathology and usefully assign eating disordered individuals to homogeneous diagnostic categories.
Eating disorders are serious, potentially life-threatening illnesses afflicting individuals through the life span, with a particular impact on both the physical and psychological development of ...children and adolescents. Because care for children and adolescents with eating disorders can be complex and resources for the treatment of eating disorders are often limited, pediatricians may be called on to not only provide medical supervision for their patients with diagnosed eating disorders but also coordinate care and advocate for appropriate services. This clinical report includes a review of common eating disorders diagnosed in children and adolescents, outlines the medical evaluation of patients suspected of having an eating disorder, presents an overview of treatment strategies, and highlights opportunities for advocacy.
Objective
Currently, there is debate in the eating disorders field regarding how to define atypical anorexia (AAN), how prevalent it is in community and clinical settings, and how AAN rates compare ...with low‐weight AN. This systematic review assesses AAN literature from 2007 to 2020, to investigate: (a) the demographic characteristics of AAN studies, (b) the prevalence of AAN compared with AN, (c) the range of operational definitions of AAN and the implications of these definitions, and (d) the proportion of patients with AAN and AN represented in consecutive admission and referral samples.
Method
PsychINFO, CINAHL, PubMed, Greylit.org, and ProQuest databases were searched according to methods for Preferred Reporting Items for Systematic Reviews and Meta‐Analyses systematic reviews, yielding 3,184 potential articles. Seventy‐five eligible studies were coded for sixty‐one variables.
Results
Clinical samples predominantly included younger, female, white samples with limited diversity. In epidemiological designs, AAN was typically as common or more common than AN, and AAN rates varied significantly based on the population studied and operational definitions. In consecutive clinical samples, AAN was frequently less represented.
Discussion
Although AAN appears to occur more frequently than AN in communities, fewer patients with AAN are being referred and admitted to eating disorder specific care, particularly in the United States. Given the significant medical and psychosocial consequences of AAN, and the importance of early intervention, this represents a crucial treatment gap. Additionally, results suggest the need for fine‐tuning diagnostic definitions, greater diversity in AAN studies, and increased screening and referral for this vulnerable population.
Resumen
Objetivo
Actualmente, hay debate en el campo de los trastornos alimenticios sobre cómo definir la anorexia atípica (ANA), cuán prevalente es en entornos comunitarios y clínicos, y cómo las tasas de ANA se comparan con AN de bajo peso. Esta revisión sistemática evalúa la literatura de ANA de 2007 a 2020, para investigar: 1) las características demográficas de los estudios de ANA, 2) la prevalencia de ANA en comparación con AN, 3) el rango de definiciones operativas de ANA y las implicaciones de estas definiciones, y 4) la proporción de pacientes con ANA y AN representados en muestras consecutivas de admisión y derivación.
Método
Las bases de datos de PsychINFO, CINAHL, PubMed, Greylit.orgy y ProQuest fueron buscados de acuerdo con los métodos preferidos para el reporte de ítems para Revisiones Sistemáticas y Metanálisis de Revisiones Sistemáticas, dando lugar a 3184 artículos potenciales. Setenta y cinco estudios elegibles fueron codificados para 61 variables.
Resultados
Las muestras clínicas incluían predominantemente muestras de femeninas, más jóvenes, y blancas con diversidad limitada. En los diseños epidemiológicos, la ANA era típicamente tan común o más común que AN, y las tasas de ANA variaban significativamente en función de la población estudiada y las definiciones operacionales. En muestras clínicas consecutivas, la ANA fue frecuentemente menos representada.
Discusión
Aunque ANA parece ocurrir con más frecuencia que AN en las comunidades, menos pacientes con ANA están siendo referidos y admitidos a la atención específica del trastorno alimentario, particularmente en los Estados Unidos. Dadas las importantes consecuencias médicas y psicosociales de ANA, y la importancia de la intervención temprana, esto representa una brecha de tratamiento crucial. Además, los resultados sugieren la necesidad de ajustar las definiciones diagnósticas, una mayor diversidad en los estudios de ANA y un mayor cribado y referencia a tratamiento para esta población vulnerable.

Purpose of Review
There is growing recognition that eating disorder (ED) symptoms, particularly those of a muscularity-oriented nature, are more common in men than previously understood. The purpose ...of the current review is to describe contemporary directions and implications of research on traditional and muscularity-oriented ED symptoms among males.
Recent Findings
Evidence indicates that ED symptoms occur in a substantial minority of men. Importantly, recent research has focused on muscularity-oriented body image and disordered eating in males, demonstrating the prevalence, correlates, and consequences of maladaptive muscularity-oriented attitudes and behaviors. A growing number of assessments are available to measure these constructs in males, and preliminary treatment considerations have begun to be addressed in the literature.
Summary
Research on male EDs and body image is increasingly focusing on muscularity-oriented manifestations. Continued empirical work will be critical to improve our understanding of the onset, maintenance, and treatment of muscularity-oriented disordered eating in males.
Objective
To update the prevalence of eating disorders in the general population before 2021 and to analyze the distribution characteristics at different times and in different regions and sexes, as ...well as the diagnostic criteria.
Methods
Based on the method from a previous report by the authors, studies were identified from the following databases: PubMed/Medline, PsycINFO, ISI Web of Knowledge, Ovid and the 4 most important Chinese databases. Articles in English and Chinese before 2021 were retrieved. The data retrieved at this time were pooled with the data from a previous report for analyses.
Results
Thirty-three studies were identified, which included 18 studies supplemented in this retrieval. The pooled lifetime and 12-month prevalence of eating disorders were 0.91% (95% CI, 0.48–1.71) and 0.43% (95% CI, 0.18–0.78), respectively. The pooled lifetime and 12-month prevalence of the subgroup EDs (any), which covers all types of eating disorders, were 1.69% and 0.72%, respectively. The lifetime prevalence of AN, BN and BED was 0.16% (95% CI, 0.06–0.31), 0.63% (95% CI, 0.33–1.02) and 1.53% (95% CI, 1.00–2.17), respectively. The lifetime prevalence of EDs in Western countries was 1.89%, and was high at 2.58% in females. Prevalence studies using DSM-5 criteria were scarce.
Conclusions
The prevalence of eating disorders might be underestimated thus far. Not all types of EDs were included in a majority of epidemiological surveys, and the prevalence rates of the new types of EDs were significantly higher. Eating disorders were especially common in Western countries and in females. New diagnostic criteria should be used to comprehensively assess all types of eating disorders.
Level of evidence
1, systematic review and meta-analysis.
Purpose of Review
This review summarizes emerging evidence for the relationship between food insecurity and eating disorder (ED) pathology, outlines priorities for future research in this area, and ...comments on considerations for clinical and public health practice.
Recent Findings
Among adults, food insecurity is cross-sectionally associated with higher levels of overall ED pathology, binge eating, compensatory behaviors, binge-eating disorder, and bulimia nervosa. Evidence for similar relationships among adolescents has been less robust; however, compared to studies of adults, there have been substantially fewer studies conducted in adolescents to date.
Summary
Emerging evidence consistently indicates that food insecurity is cross-sectionally associated with bulimic-spectrum ED pathology among adults. Findings emphasize the need for ED research to include marginalized populations who have historically been overlooked in the ED field. Much more research is needed to better understand the relationship between food insecurity and ED pathology and to determine effective ways to intervene.
Despite their high prevalence, associated morbidity and mortality, and available treatment options, eating disorders (EDs) continue to be underdiagnosed by pediatric professionals. Many adolescents ...go untreated, do not recover, or reach only partial recovery. Higher rates of EDs are seen now in younger children, boys, and minority groups; EDs are increasingly recognized in patients with previous histories of obesity. Medical complications are common in both full and subthreshold EDs and affect every organ system. No single cause of EDs has emerged, although neurobiological and genetic predispositions are emerging as important. Recent treatment paradigms acknowledge that they are not caused by families or chosen by patients. EDs present differently in pediatric populations, and providers should have a high index of suspicion using new Diagnostic and Statistical Manual, 5th edition diagnostic criteria because early intervention can affect prognosis. Outpatient family-based treatment focused on weight restoration, reducing blame, and empowering caregivers has emerged as particularly effective; cognitive behavioral therapy, individual therapy, and higher levels of care may also be appropriate. Pharmacotherapy is useful in specific contexts. Full weight restoration is critical, often involves high-calorie diets, and must allow for continued growth and development; weight maintenance is typically inappropriate in pediatric populations. Physical, nutritional, behavioral, and psychological health are all metrics of a full recovery, and pediatric EDs have a good prognosis with appropriate care. ED prevention efforts should work toward aligning with families and understanding the impact of antiobesity efforts. Primary care providers can be key players in treatment success.
