The goal of this clinical trial (cluster randomized controlled trial) is to learn whether a Positive Deviance/Hearth (PDH) intervention can effectively treat moderate acute malnutrition (MAM) and reduce relapse compared to standard care in children aged 6-59 months diagnosed with MAM in Bangladesh. The main questions it aims to answer are:
* Does the PDH intervention improve recovery rates among children with MAM?
* Does the PDH intervention reduce relapse to MAM or progression to severe acute malnutrition (SAM) after recovery?
Researchers will compare communities receiving the PDH intervention to communities receiving standard nutrition care (e.g., usual counseling or supplementary feeding programs) to see if PDH leads to better nutritional recovery and sustained outcomes.
Participants will:
* Take part in a 12-day "Hearth" nutrition education program where caregivers prepare and feed children nutrient-dense meals using local foods
* Receive 2 weeks of home follow-up visits by volunteers after the Hearth sessions, along with ongoing growth monitoring and counseling twice per month
* Undergo periodic anthropometric assessments (weight, height/length, Mid-upper arm circumference (MUAC)) at key time points
