Community Interventions to Improve Iron and Iodine Status in Mother and Child Dyads in Northern Ghana

BACKGROUND Ghana has reduced food insecurity prevalence by 49.2% in two decades. However, prevalence of malnutrition especially stunting (in \<children5yr) has not matched the changes in food security levels. Of several key nutritional factors that lead to stunting, nutritional status of such trace minerals as iodine, iron and zinc has not been studied. Nutritional inadequacy of these trace minerals may be detected by estimation of dietary intake, and time-consuming and costly biochemical measurements of respective biomarkers. Since there is no means to estimate dietary intake of the trace minerals in Ghana, due to incomplete food composition data of the nutrients, identifying validated non-invasive, dietary approaches to predict the biomarker status of these trace minerals are critical in counteracting the challenges surrounding the persistent stunting due to micronutrient deficiencies in Ghana. Additionally, exploring alternative approaches to providing access to foods rich in trace minerals at household level is crucial. STUDY AIMS AND HYPOTHESIS The ultimate goal of this research is to increase knowledge base on improving trace mineral status in mother-child (6-23 mo) dyads through a sustainable community-based interventions in northern Ghana. Investigators will begin with iron and iodine that impair mothers and young children's growth and cognitive development most with three aims: 1) to develop dietary screening tools that are validated by biomarkers for early detection of deficiencies, 2) to determine efficacy (dose responses) of feeding indigenous nutrient-rich meals in preventing deficiencies and improving iron and iodine status, and 3) to demonstrate sustainable and scalable improvement of food systems through a container gardening project for iron-rich Hibiscus sabdarifa for consumption and income by empowering women during the dry/lean season in northern Ghana. • Aims 1: To develop dietary screening tools that are validated by biomarkers for early dete
