Hochsch., Diss., 2008 %X Excessive physical activity is perceived as a significant clinical feature of anorexia nervosa and bulimia nervosa which may often raise difficulties in treatment. Eating disorder patients often demonstrate obligatory, pathological attitudes towards exercise. The present study aimed to examine excessive physical activity in adolescents with eating disorders. Therefore a multidimensional assessment was realized including assessment of the quantitative and the qualitative aspects of physical activity. Assessment of associated features was also conducted. The quantity and quality of daily physical activity of 46 adolescent outpatients with anorexia nervosa and bulimia nervosa and 19 healthy controls were assessed by accelerometry and self-reports. In addition, eating disorder psychopathology, general psychopathology and physiologic parameters were assessed as were motivation for physical activity and exercise feelings. Contrary to the hypothesis, eating disorder patients and controls did not differ in the objectively recorded global physical activity. On a closer look, however, eating disorder patients reported higher levels of motor restlessness than controls. Furthermore, adolescents suffering from an eating disorder differed from controls in their feelings towards exercising; the patients showed higher scores of exercise dependence. Concerning relevant physiological parameters there was evidence of a negative linear relationship between serum leptin levels and the level of physical activity in patients with anorexia nervosa only. In the total eating disorder group there was no significant relationship between further psychopathological parameters and physical activity. The results indicated that differences in physical activity between eating disorder adolescents and healthy controls are better described in qualitative features rather than in quantitative domains. Depending on the stage of disease, the degree and form of physical activity seem to vary; this conveys methodical difficulties in adequate measurement of physical activity. Prospective studies are needed for replicating the present findings and for extracting possible relevant parameters in the different stages of disease. For establishing specific interventions, feelings and attitudes towards exercise should be integrated into diagnostic investigation. %K Körperliche Aktivität (SWD) %K Essstörung (SWD) %K Anorexia nervosa (SWD) %K Bulimie (SWD) %F PUB:(DE-HGF)11 %9 Dissertation / PhD Thesis %U https://publications.rwth-aachen.de/record/50178
