Abstract

Subsequent to an epidemiological study on eating behaviour in adolescents, a prospective study was carried out to examine the effect of health promotion lessons on disturbed eating behaviour. From the original sample (t1, n = 1944), a subgroup of 314 students of both sexes, 14-19 years of age, was selected. Participants came from a total of 20 classes in which a high percentage of students exhibited disturbed eating behaviour. Ten classes were then randomly selected to receive health promotion lessons (intervention group, high-risk; IGHR), while the other 10 classes served as controls (control group, high-risk; CGHR). The Eating Attitudes Test (EAT-26), the Giessen Physical Complaint List for Children and Adolescents (GSCL-C) and the Self-Report Symptom Check-List (SCL-90-R) were administered shortly before (t2) and 3 months after (t3) the interventions. The three health promotion lessons dealt with issues concerning beauty ideals, gender differences in psychosexual maturation and body awareness, healthy eating behaviour, physiology of nutrition, early symptoms of eating disorders and therapeutic approaches. The data analyses revealed an improvement on all three symptom scales for both groups between t2 and t3, but there were no significant differences between the IGHR and CGHR groups. When data from high-scoring female participants only were analysed (HRf-IGHR and HRf-CGHR), the multivariate analysis revealed a significant interaction between time and group (15.2% of variance explained). Our experiences in implementing health promotion lessons that conveyed knowledge about eating disorders and addressed physical and psychological issues in a more general way indicated that these interventions can be carried out in schools, and may contribute to increases in physical and psychological well-being in a high-risk population of adolescents.
