On October 17, 2023, MOMENTUM Country and Global Leadership held a workshop to build on discussions linking adolescent-responsive health systems to Universal Health Coverage during Global Forum for Adolescents. The workshop provided an introduction to the adolescent- and gender- responsive health systems approach; shared practical guidance on how to use the assessment and action planning tool, showcasing experiences in El Salvador, Kenya, Sierra Leone, and Zambia; and provided opportunities for questions and discussion on how to use the findings to take action to strengthen the health system to meet the needs of adolescents and address gendered barriers to care.
