Many aspects of the motivation to eat are involved in the impairment of adequate food intake and body weight control. The aim of this study was to evaluate, by adopting widely used eating questionnaires, the Three Factors Eating Behaviour Questionnaire (TFEQ) and the Dutch Eating Behavior Questionnaire (DEBQ), the associations of different antipsychotic medications with the food attitudes of 153 schizophrenic patients: we compared 93 individuals treated with atypical antipsychotics, 27 treated with conventional neuroleptics and 33 untreated patients. We did not find any difference according to sex, but the mean body mass index varied significantly among the three groups of patients. The DEBQ external eating factor was higher in patients treated with atypical antipsychotics than in patients who received conventional neuroleptics (P=0.035). The TFEQ disinhibition and DEBQ emotional eating scores tended to change among the three types of treatment. Patients with metabolic syndrome (19%) had lower DEBQ external eating scores (P=0.044) and a tendency of higher TFEQ disinhibition scores. The TFEQ disinhibition and hunger scores increased according to the body mass index (P=0.003; P=0.017). The main outcome of this study is that the patients treated with atypical antipsychotics were more reactive to external eating cues, which could partly explain the higher weight gain often reported in these patients.
