This brief highlights the key components of the HFS Behavior Change Communication and Community Mobilization Strategy, which is a core component of the HFS approach. The strategy aims to promote recommended MNH and FP practices and build an enabling environment and social support for MNH and FP, in order to improve health outcomes. Key HFS activities include: antenatal and postpartum home visits, community mobilization sessions, engagement of local champions, and advocacy through ward-level meetings. HFS activities use strategic, field tested messages and materials informed by formative assessment.
