This study aims to address a crucial knowledge gap by conducting formative, process, and summative evaluation of an 'enhanced' mHealth approach for promotion of maternal, infant, and young children nutrition (MIYCN) using a social and behavior change communication (SBCC) framework. Examples of mHealth interventions include the formation of a short message service (SMS) network for delivering brief MIYCN messages of use of a mobile phone-based algorithm for nutrition counseling to strengthen MIYCN education and counseling for community participants.
