Resumen

Introduction: In Peru, incomplete sex education among adolescents is associated with high rates of early pregnancy and sexually transmitted infections, limiting informed and responsible decision-making in reproductive health. Educational interventions are a key strategy for prevention and promotion. Objective. To evaluate the effect of the EDUSE program on the level of knowledge about comprehensive sex education in first-year secondary school students. Methods. Pre-experimental study with pre-and post-intervention measurements in 209 adolescents. A validated questionnaire was used to assess four dimensions: identity and body image, autonomy and self-care, critical thinking, and affectivity. The intervention consisted of seven participatory educational sessions. The McNemar test was used with a significance level of p<0.05. Results. A significant increase was observed in identity and physicality (75.1%→94.3%, p<0,001), autonomy and self-care (75.1%→92.8% p<0,001), critical thinking [Formula In Abstract], and affectivity (27.3%→62.2%, p<0,001). Seventy percent of the items showed statistically significant differences. Conclusion. The EDUSE program significantly improved adolescents' knowledge of Comprehensive Sexual Education, demonstrating its potential as a preventive educational strategy in the school environment.
