Formulation and acceptability of local nutrient‐dense foods for young children: A formative study for the Child Health, Agriculture and Integrated Nutrition (CHAIN) Trial in rural Zimbabwe.

Stunting affects almost one‐quarter of children globally, leading to reduced human capacity and increased long‐term risk of chronic disease. Despite intensive infant and young child feeding (IYCF) interventions, many children do not meet their requirements for essential nutrients. This study aimed to assess the feasibility of implementing an IYCF intervention utilizing nutrient‐dense powders from egg, biofortified sugar beans and Moringa oleifera leaf in rural Zimbabwe. A mixed‐methods formative study was conducted comprising the following: (i) a recipe formulation trial, (ii) trials of improved practices to assess acceptability of the intervention, and (iii) a participatory message formulation process to develop counselling modules for the IYCF‐plus intervention. Twenty‐seven mother–baby pairs were recruited between November 2019 and April 2020. Key domains affecting IYCF practices that emerged were time, emotional and physical space, cultural and religious beliefs, indigenous knowledge systems and gender dynamics. Household observations and sensory evaluation indicated high acceptability of the new ingredients. Recipe formulation and participatory message formulation by participants instilled community ownership and served to demystify existing misconceptions about the new food products. Families noted the potential for intervention sustainability because the foods could be grown locally. Supplementing complementary foods with nutrient‐dense local food ingredients as powders has the potential to sustainably address nutrient‐gaps in the diets of young children living in rural lower‐ and middle‐income countries. Comprehensive IYCF counselling utilizing a gender‐lens approach, family support and indigenous knowledge systems or resources are key elements to support positive behaviour change in complementary feeding interventions. Key messages: Incorporating locally available solid foods into complementary feeding is a major challenge for caregivers in rural communities. There are several barriers that hinder mothers from feeding nutrient‐dense solid foods such as animal source foods, fruits and vegetables, resulting in nondiversified complementary diets.Formulation of nutrient‐dense, high‐quality protein complementary meals using powdered locally available food supplements is feasible, well tolerated and allows young children to be fed nutrient‐dense complementary meals in rural LMICs.Utilizing traditionally recognized functional foods such as Moringa olifeira encourages the involvement of elderly women/grandmothers in infant and young child feeding, enabling support for mothers.Integrated complementary feeding interventions incorporating behaviour change communication, provision/promotion of specific nutrient‐dense complementary foods (SQ‐LNS and local foods as powdered supplements), family support and agricultural production has potential for success in rural settings.
