简要总结
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.

入选标准
- •Households with at least one child in the 6-35 month age range in August 2015, who had at least one household member attend a field day demonstrating Quality Protein Maize, and who provided informed consent for participation and data collection were eligible for inclusion.
排除标准
- •Households in the study areas that do not have a member who attends a field day demonstrating Quality Protein Maize or who do not have a child in the appropriate age range are excluded from the study. Furthermore, households where the mother or children did not intend on staying in the region for the study duration (until the completion of the endline survey) were excluded from the study. Finally, we excluded participants who do not have access to land for crop cultivation.
