Objectives: To assess the effect of a multicomponent intervention on parental knowledge, sun avoidance behaviors, and sun protection practices in children 3-10 years. Methods: A randomized trial at a pediatric clinic recruited 197 caregiver-child pairs (90% parents). Intervention included a brief presentation and brochure for the parent and educational video and sun protection incentives for the child. Results: Significant improvements were observed in sun protection practices and parental knowledge but not in sun avoidance behaviors. Conclusion: Although results support the intervention's effect on parent-child pairs for sun protection practices and parental knowledge, increasing sun avoidance behaviors may require further study.
