[Relationship between eating behavior and distribution of body fat].

In these recent few years the study of the pathogenesis of obesity include the observation of the difference in eating behaviour between obese and non obese subjects. Therefore, current therapies now take into account, among others, also a program of behavioural therapy. On the other hand, recent studies have revealed the role of different body fat distribution on the obesity prognosis, especially considering cardiovascular risk factors. To this purpose much attention has been focused on the measurement of waist and hips circumferences and their ratio (WHR) considered important predictors of risk associated with obesity. Aim of this study was the observation of some differences in eating habits and psychological status during a 24-hr period in relationship with the android or gynecoid type of obesity. 102 outpatients were divided in two groups: 1) with WHR less than 0.85; 2) with WHR greater than or equal to 0.85. All subjects were given a questionnaire in which by a scale from 0 to 3 they expressed their appetite sensation during different hours of the day. In addition, they indicated their motivation to loose body weight. Our results demonstrated that subjects with WHR greater than or equal to 0.85 showed higher appetite sensation, during the whole day, with a peak at lunch, in comparison with subjects with WHR less than 0.85. Subjects with gynecoid type of obesity seemed to pay much attention to their body image than subjects with android type of obesity and complained less physical disorders than subjects of the second group. These preliminary data seem to suggest a non-secondary role of behavioural pattern in obesity also by affecting the different regional fat distribution.
