Moderate Acute Malnutrition (MAM)

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

Wasting (severe thinness) is a common and serious problem among young children in rural Guinea-Bissau. Community Health Agents (CHAs) can help prevent malnutrition by regularly measuring children's growth and advising families on nutritious local foods. However, this practice is not consistently implemented. This pilot study will test whether implementing Regular Growth Monitoring (RGM) by CHAs every month is feasible and effective in reducing malnutrition among children aged 6 months to 5 years in two rural villages. Investigators will also compare three methods for measuring mid-upper arm circumference (MUAC), which is used to detect malnutrition: the standard WHO tape measure, a photograph of the arm, and a simple bracelet. The goal is to identify which method is easiest for CHAs to use reliably. Baseline and final measurements will be taken in both villages. One village will receive the monthly RGM intervention first, followed by the second village. Families will also be asked about their experiences with the program through brief questionnaires.
