Context: Sexual education is not taught to most of the children. This can bring about negative effects on different dimensions of one's sexual health. However, talking to children constantly but briefly can have positive effects on their relationships and sexual health. Therefore, this study aimed at reviewing different types of educational intervention related to the sexual health of children under 12. Evidence Acquisition: In this narrative review, Google Scholar, PubMed, Scopus, Science Direct and Web of Science databases were searched using the following keywords: "sex education, sexual education, sexual health, sexual training and children". Two researchers (ZB and MR) searched articles related to children's sexual health up to December 2018. Results: Findings were categorized into 4 levels: 1-children-focused interventions: sexuality education coaching program, child sexual abuse prevention program, body image, and decrease in gender-typed remarks. 2-parent-focused interventions: child sexual abuse prevention education and child sexual training. 3-children-and parent-focused interventions: HIV/AIDS prevention program and saving sex for later. 4-The Impact of culture and religion. Conclusions: Sexual health in childhood can guarantee the sexual health of the coming years of life; therefore, it is worthwhile to pay attention to this issue and set plans and policies in familial and social aspects based on interventions included in this study.
