Objective: To determine the impact of a peer-led, school-based programme (Students As LifeStyle Activists; SALSA) on energy balance–related behaviours (EBRBs) in Grade 8 students, and the cost of implementing the programme.
Conclusion: The SALSA peer education programme had a positive impact on most of the dietary EBRBs examined. The cost evaluation showed that it is a relatively low-cost programme to implement.
