RESUMEN
School involvement is essential for providing Children's Sexual Health (CSH), but Health Care Providers (HCPs) responsible for children's health at schools are not sufficiently competent. This study aimed to determine the effect of the Children's Sexual Health Education Program (CSHEP) on the knowledge and attitude of HCPs in elementary schools. Sixty HCPs were randomly assigned to two groups. The intervention was held in four 90-minute training sessions. Questionnaires were completed by the intervention and control groups in three stages (before, immediately after, and 4 weeks after the intervention). At the end of the intervention, a training session was held in the control group. CSHEP has been effective in improving the knowledge and attitude of HCPs about CSH. Given the important role of HCPs in CSH and their need for education, planning for continuing education courses to promote their knowledge and attitude seems essential.
