A major challenge in TB policy and programming is that gender-related barriers, especially those affecting men, young people, and other marginalised groups, are often recognised but not adequately translated into practical guidance, measurable indicators, or targeted action.
This case study shows how the LIGHT Consortium helped address that gap by generating relevant evidence, providing technical input, and working closely with national TB stakeholders in Kenya, Uganda, Nigeria, and Malawi to strengthen strategic plans, guidelines, and review processes. Across these countries, LIGHT sustained engagement with key national stakeholders, contributed to more gender-responsive and inclusive TB policies and helped ensure that national responses better reflect the realities shaping access to care and outcomes. Beyond influencing policy documents, LIGHT helped shift how gender and TB are understood, strengthening relationships between researchers and decision-makers, and helping keep equity, community rights, and people-centred care on the agenda. Together, these contributions show how research can do more than generate knowledge: it can help shape stronger systems, better policies, and more equitable TB responses in practice.
