Effectiveness of behavioral interventions on knowledge, attitude, and adherence to prenatal MMSs among pregnant women in Ethiopia: a post-test only cluster randomized controlled trial

Multiple Micronutrient Supplementation (MMS) has been identified as a vital strategy to enhance maternal health; however, achieving sustained adherence remains challenging. There is insufficient evidence on the potential of contextually appropriate behavioral interventions to improve MMS-related knowledge, attitudes, and adherence beyond routine antenatal care. Thus, this trial was designed to provide empirical evidence on whether these specific strategies could improve MMS knowledge, attitudes, and adherence among pregnant women in Ethiopia. Overall, the findings suggest that behaviorally informed approaches may have potential to support MMS adherence when integrated with routine maternal health services.
