Sustainability and adherence to behaviour change: a cross-sectional 3-year follow-up survey of an innovative Community Mobilisation and Community Incentivisation strategy (CoMIC trial) for child health in rural Pakistan

Summary: Background: Infectious diseases remain the leading cause of death among children younger than 5 years due to disparities in access and acceptance of essential interventions. The Community Mobilisation and Community Incentivisation (CoMIC) trial was designed to evaluate a customised community mobilisation and incentivisation strategy for improving coverage of evidence-based interventions for child health in Pakistan. This unplanned follow-up study was designed to assess the health effects, adherence to behaviour change, and sustainability of this strategy 3 years after the completion of the trial.
