Abstract:
The aim of this study was to assess the effects of 2 German school-based primary prevention programmes for (pre)adolescents, aged 11-13 years, with 9 manual-guided lessons. 92 (PriMa, n=1,553 girls) and 22 (Torera, n=256 boys, 277 girls) Thuringian secondary schools participated in controlled trials with pre-post assessment. Girls and students at risk showed significant improvements of conspicuous eating behaviour and body self-esteem with small to medium effect sizes. Implementation costs were € 2.50 per student.
