Integrating group antenatal care into routine services: a registry-based cohort study in Geita, Tanzania

In routine settings, G-ANC was associated with high ANC attendance, strong uptake of essential interventions, and positive birth outcomes. Integration appears feasible within public systems, though adaptations are needed to promote earlier initiation and alignment with the WHO eight-contact model. Further research should examine costs, feasibility, scalability, and long-term impact.
