In collaboration with the Federal Government of Nigeria and Bauchi State, Nutrition International (NI) conducted a three-year implementation research study to assess whether adherence solutions - developed through a human-centered designed (HCD) approach - could improve adherence to multiple micronutrient supplementation (MMS) among pregnant women in Nigeria. These set of adherence solutions focused on strengthening the capacity of healthcare workers and community members, improving nutrition counselling within antenatal care, and engaging pregnant women' family members to support consistent MMS intake.
