Prevalence and Correlates of Eating Disorders in Adolescents

Abstract

Context Eating disorders are severe conditions, but little is known about the prevalence or correlates of these disorders from population-based surveys of adolescents. Objectives To examine the prevalence and correlates of eating disorders in a large, reprefentative sample of US adolescents. Design Cross-sectional survey of adolescents with face-to-face interviews using a modified version of the Composite International Diagnostic Interview. Setting Combined household and school adolescent samples. Participants Nationally representative sample of 10 123 adolescents aged 13 to 18 years. Main Outcome Measures Prevalence and correlates of eating disorders and subthreshold conditions. Results Lifetime prevalence estimates of anorexia nervosa, bulimia nervosa, and binge-eating disorder were 0.3%, 0.9%, and 1.6%, respectively. Important differences were observed between eating disorder subtypes concerning sociodemographic correlates, psychiatric comorbidity, role impairment, and suicidality. Although the majority of adolescents with an eating disorder sought some form of treatment, only a minority received treatment specifically for their eating or weight problems. Analyses of 2 related subthreshold conditions suggest that these conditions are often clinically significant. Conclusions Eating disorders and subthreshold eating conditions are prevalent in the general adolescent population. Their impact is demonstrated by generally strong associations with other psychiatric disorders, role impairment, and suicidality. The unmet treatment needs in the adolescent population place these disorders as important public health concerns.

Renal Involvement in Psychological Eating Disorders

“…According to DSM-IV [1], they include anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder and EDs not otherwise specified (EDNOS). Psychological EDs are an increasing public health problem [2] with severe clinical manifestations: hypothermia, hypotension, electrolyte imbalance, endocrine disorders and kidney failure. AN is characterized by a severely calorie-restricted diet, resulting in a body weight that is at least 85% below that expected for age and height.…”

Epidemiology of eating disorders part III: social epidemiology and case definitions revisited

“…The probability of mood disorders to appear seems lower in anorexia nervosa, i.e., OR 0.7; CI95 0.3-2.0 (Swanson et al, 2011) and only slightly increased in subclinical disorders (i.e., OR 1.7; CI95 0.5-5.8, and 1.8; CI95 0.4-9.0 for a major depressive disorder and dysthymia, respectively). In community studies (e.g., Swanson et al, 2011) the comorbidity is likely for any mood disorder in bulimia (OR 5.7; CI95 3.2-9.9) and BED (OR 4.76 CI95 2.7-7.7).…”

“…In community studies (e.g., Swanson et al, 2011) the comorbidity is likely for any mood disorder in bulimia (OR 5.7; CI95 3.2-9.9) and BED (OR 4.76 CI95 2.7-7.7). Among subclinical bulimia there is a high risk for major depressive disorder (OR 10.2; and dysthymia (OR 6.3; CI95 2.3-17.1).…”

“…Also, a 58% proportion has been reported for moderate to severe depression (Fennig & Hadas, 2010). Moreover, the recent study by Bühren et al (2014) which indicates a lower overall proportion of comorbidity still reports a higher level of comorbid mood disorder (35%) than anxiety disorders (11%), notably accounted for by the proportion of major depressive disorder (32%).The probability of mood disorders to appear seems lower in anorexia nervosa, i.e., OR 0.7; CI95 0.3-2.0 (Swanson et al, 2011) and only slightly increased in subclinical disorders (i.e., OR 1.7; CI95 0.5-5.8, and 1.8; CI95 0.4-9.0 for a major depressive disorder and dysthymia, respectively). In community studies (e.g., Swanson et al, 2011) the comorbidity is likely for any mood disorder in bulimia (OR 5.7; CI95 3.2-9.9) and BED (OR 4.76 CI95 2.7-7.7).…”

Selbstregulation bei Essstörungen und Adipositas – Implikationen für die Behandlung

“…Die Lebenszeitprävalenz beträgt 0,6% und die 12-Monats-Prävalenz in der Hochrisikogruppe der 13-bis 18-jährigen Jugendlichen 0,2% [Hudson et al, 2007;Swanson et al, 2011]. AN kann mit schweren medizinischen Spätfolgen assoziiert sein und weist eine hohe Komorbiditäts-und die höchste Mortalitäts-rate psychischer Störungen auf [Steinhausen, 2009] …”
