Translating Adoption of Improved Varieties Into Nutritional Impact
View on ClinicalTrials.gov
Updated Dec 15, 2025
Brief Summary
The purposes of this study are (1) to determine whether child nutrition-focused adoption encouragement messages focused on Quality Protein Maize (QPM) and the availability of small quantities of QPM seed can be effective at increasing QPM adoption and health outcomes for young children, and (2) to determine whether consumption encouragement messages and techniques (e.g., containers for earmarking) can be effective at increasing QPM targeting to and health outcomes for young children.
Interventions
Name:
Adoption Encouragement Treatment
Type:
OTHER
Description:
Households in the Adoption Encouragement Treatment received child nutrition focused guidance on the nutritional and agronomic benefits of Quality Protein Maize (QPM) adoption, and the opportunity to order up to 6 kg of QPM seed to plant in their own fields.
Name:
Consumption Encouragement Treatment
Type:
OTHER
Description:
Households in the Consumption Encouragement Treatment received the same guidance as households in the Adoption Encouragement Treatment, as well as additional guidance on the importance of specifically targeting foods made with QPM to young children and tools to help households keep the grain separate and remember to feed QPM-based foods to the young children.
