[Psychopathological and clinical features among the ambulatory population of obese patients].

Aim of the present study is the evaluation of psychopathological and clinical features of these outpatients followed by the Outpatient Clinic of the Section of Metabolic Diseases and Diabetes, University of Florence. 84 obese patients and 217 non-obese control subjects were studied using the Structured Clinical Interview for DSM-III-R (SCID), and applying DSM-IV criteria for Binge Eating Disorder. BITE self-reported questionnaire, STAI inventory and Ham-D rating scale were also used. Lifetime prevalence of Binge Eating Disorder in obese patient was 11.9%, markedly lower than that reported in studies on North American samples. Prevalence of depressive disorder (Major Depression and Dysthymia) was significantly higher (p < 0.005) in obese patients than in control subjects. This confirms the important relationships between eating and mood disorders. The prevalence of subclinical eating disorders resulted to be significantly higher in obese patients (p < 0.01) when compared with control subjects. Significant correlations (p < 0.01) of BITE scores were observed with STAI and Ham-D scores, but not with body mass index. These results underline the need for an accurate psychopathological assessment in obese patients, in order to formulate a correct diagnosis and plan adequate therapeutical interventions.
