Abstract: Objective: To evaluate the effectiveness of a theory-based intervention to reduce the intention to use restrictive dietary behaviors for losing weight among adolescent female athletes involved in aesthetic sports. Design: Cluster randomized controlled trial. Setting: Aesthetic sport teams of adolescent (age 12-17) female athletes. Participants: Two teams (n=37 athletes) in the intervention group and 3 teams (n=33) in the comparison group. Interventions: The 2 groups received nutrition education during 3 weekly 60-min sessions. The intervention group was further exposed to a theory-based intervention targeting the specific determinant of intention to use restrictive dietary behaviors for losing weight, namely attitude. Main Outcome Measures: Difference over time between groups in intention to use restrictive dietary behaviors for losing weight and in nutrition knowledge. Analysis: Mixed models for repeated measures. Results: The theory-based intervention contributed to maintaining a low intention of using restrictive dietary behaviors for losing weight over time in the intervention group compared to the comparison group. Nutrition knowledge score increased equally in both groups. Conclusion and implications: Complementing nutrition education with theory-based behavior change intervention may help maintain a low intention of using restrictive dietary behaviors for losing weight among high-school female athletes involved in aesthetic sports
