PURPOSE: This study examined the effect of 2 school-based interventions on adolescents' consumption and knowledge of fish with the hypothesis that home economics education would enhance the effect of modifications in the school canteen. The school lunch intervention (SL) focused on changes in the school canteen, and the school lunch + home economics intervention (SL + HE) in addition consisted of changes in the home economics syllabus. Pupils in the 8th grade (n = 228) from 3 schools in Göteborg, Sweden, participated (control, n = 83; SL group, n = 58; SL + HE group, n = 87). METHODS: A controlled design was used in which behavior and knowledge were assessed before and after the intervention. In contrast to much previous research of this type, measurement of behavior was based primarily on direct observation as opposed to self-reported intakes. Behavior (fish consumption) was measured individually by structured observations in the school canteen 5 times (once a week) when fish was served. Nutritional knowledge was measured by means of 10 items in a questionnaire. To analyze changes in behavior, a nonparametric statistical method assessing systematic change in paired ordered categoric variables was used. RESULTS: At follow-up evaluation, consumption had increased significantly in the SL + HE group, a change that also differed from the control group. In addition, significant positive changes in knowledge were observed in both intervention groups, but not in controls. CONCLUSIONS: The results suggest that dietary change was achieved by modifying conditions in the school canteen together with changing the home economics syllabus. This study shows the importance of the school in the promotion of dietary change among adolescents.
