UNASSIGNED: We aimed to assess the prevalence, incidence, age-of-onset and diagnostic stability of threshold and subthreshold @entity1278 ( @entity1279 ) in the community. Data come from a prospective-longitudinal community study of 3021 subjects aged 14-24 at baseline, who were followed up at three assessment waves over 10  years. @entity1277 ( @entity1277 ) symptomatology was assessed with the DSM-IV/M-CIDI at each wave. Diagnostic stability was defined as the proportion of individuals still affected with at least symptomatic @entity1277 ( @entity1277 ) at follow-ups. Baseline lifetime prevalence for any threshold @entity1277 were 2.9  % among females and 0.1  % among males. For any subthreshold @entity1277 lifetime prevalence were 2.2  % for females and 0.7  % for males. Symptomatic expressions of @entity1277 (including core symptoms of the @entity74 ) were most common with a lifetime prevalence of 11.5  % among females and 1.8  % among males. Symptomatic AN showed the earliest onset with a considerable proportion of cases emerging in childhood. 47  % of initial threshold AN cases and 42  % of initial threshold @entity1279 cases showed at least symptomatic expressions of any @entity1277 at any follow-up assessment. Stability for subthreshold @entity1277 and symptomatic expressions was 14-36  %. While threshold @entity1277 are rare, @entity1277 symptomatology is common particularly in female adolescents and young @entity1 . Especially threshold @entity1277 are associated with a substantial risk for stability. A considerable degree of symptom fluctuation is characteristic especially for subthreshold @entity1277 .
