This chapter aims to explore the intersectionality theory and the Bioecological theory of human development, highlighting potential convergences and limitations in their theoretical dialogue for understanding violence against children and adolescents. By analyzing situations of violence across different contexts, the chapter illustrates how the health field can benefit from integrating an intersectional analytical lens into the ecological framework. Rooted in Black feminism thought, intersectionality offers a critical perspective to examine how systems of oppression shape children’s and adolescents’ developmental trajectories and experiences of violence in complex and interconnected ways. Considering categories such as race, class, gender, sexual orientation, nationality, and citizenship status, as well as their intersections, is essential for designing inclusive and effective health policies aimed at fostering a more equitable and safe society for all children and adolescents.
