Many studies have analysed psychopathological dimensions of relationship that adolescent have with food and body. But few researches have focused attention on links between psychosocial dimensions such as social representations (Moscovici, S. 1961; Lalhou, S.1995) and adolescent typical practices of eating (with family and peers) and body (diet and sport). This research is aimed to describe and to analyse representations and practices of eating and body of 60 adolescents (30 females, 30 males) equally distributed on high and low social class aged from 14 to 16 years. Hypothesis supposes changes of eating and body representations and practices according to sexe and social class of subjects. A multimethodogical approach was adopted. Data were collected in Avril 1999 in two roman colleges. Qualitative and quantitative instruments were administered in this order: a) associative network (words association), b) semi-structured interviews (18 questions about eating and body ideas and practices), c) body drawing, d) eating family drawing, e) questionnaires (Eating Attitudes Test, Eating Disorders Inventory 2). A preliminary interviews content analysis with ALCESTE (Reinert, M.1993) draw out 8 discourse classes. Four classes are linked to eating representations and practices: a) Eating Family Practice (16,85 %); b) Eating with Friends (8, 61%); c) Eating quantity and preferences (15, 97%); d) Daily meals organisation (7,40%). Others four classes are linked to body representations and practices: e) Eating Problems (20, 13%); f) Body Health and beauty (8,07%); g) Diets and Sports ( 10,86%); h) Food quality (12, 10%). Results show a general picture of eating and body representations and practices. Eating with family is a very important social situation: a script characterised by social actors, rules, actions and contexts is outlined. Food intake control and food preferences seem pregnant dimensions in identity construction process face to family and peers. Naive theories about eating disorders are constructed. Finally diet, sport and food quality seem central in shaping and modelling body. [less ▲]

From a metabolic point of view, anorexia nervosa may be viewed as a mirror image of obesity. We compared insulin secretion, clearance and action on glucose metabolism during an intravenous glucose tolerance test in nine women with anorexia nervosa and in nine age-matched normal-weight controls. Insulin secretion (ISR) was derived by deconvolution of plasma C-peptide levels, insulin clearance (MCR(I)) was obtained by dividing the area under the curve (AUC(0-180 min)) of ISR by the corresponding AUC of plasma insulin levels, insulin sensitivity (S(I)) and glucose effectiveness index (S(G)) were calculated by Bergman's minimal model. The anorectic women had markedly lower BMI values (13.7+/-0.6 vs 23.2+/-0.8 kg/m2, p<0.0001) and serum basal leptin levels (2.8+/-0.6 vs 8.9+/-1.8 ng/mL, p=0.005) than control women. The anorectic women exhibited clear-cut lower fasting and post-glucose plasma insulin levels but similar corresponding plasma C-peptide concentrations when compared to controls. Consequently, ISR was similar in both groups while MCR(I) was significantly increased in anorexia nervosa (MCR(I): 3320+/-881 vs 822+/-79 mL x min(-1) x m(-2), p<0.02). The index S(I) tended to be higher in anorectic women than in normal-weight subjects, but without reaching the level of statistical significance because of a high between-subject variability (20.2+/-5.7 vs 12.5+/-2.2 10(-5) x min(-1)/pmol x L(-1), NS). The index S(G) was similar in both groups (0.022+/-0.004 vs 0.018+/-0.002 min(-1), NS). In conclusion, low plasma insulin levels observed in women with anorexia nervosa result from high MCR(I) rather than from depressed insulin secretion. Insulin sensitivity is not systematically increased and glucose effectiveness is unchanged in anorectic women when compared to normal-weight controls. [less ▲]
