Evaluating the Impact of Text Messages and Interpersonal Community Support Groups on MICN Practices in Tanzania

This cluster randomized controlled study aims to add to the evidence base on mHealth interventions by assessing the main effects of delivering nutrition messages on key maternal, infant, and young child nutrition (MIYCN) behaviors and outcomes through three innovative behavior change strategies. The strategies compared will be: (i) an interpersonal communication strategy using the Tanzanian government's Mkoba wa Siku 1000 maternal, infant and young child nutrition (MIYCN) curriculum (MwS) through clinic- and community-based channels, (ii) the mNutrition SMS text messaging module of the government's Wazazi Nipendeni program, and (iii) the combination of both of these strategies (interpersonal and SMS messaging). They will be compared with the current standard of care in Tanzania. The goal will be to determine which has the greatest impact on key MIYCN and hygiene practices and care-seeking behaviors. It will be paired with a costing analysis so that these effects can be understood in the context of their costs.
