Effectiveness of Positive Deviance/Hearth in Treating Uncomplicated Moderate Acute Malnutrition in Children 6-59 Months in Mymensingh Division, Bangladesh (PD/Hearth MAM)

8 mei 2026 bijgewerkt door: World Vision US

The Effectiveness of Positive Deviance/Hearth (PDH), a Local Dietary Approach, to Treat Uncomplicated Moderate Acute Malnutrition (MAM) in Children 6-59 Months in Mymensingh, Bangladesh

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

Wapens en interventies

Deelnemersgroep / Arm
Interventie / Behandeling
Ander: Standard of Care (SOC) group
SOC group will receive basic health and nutrition interventions that align with Ministry of Health's protocols.
Ander: Standard of Care (Investigator Selected)
Children will receive basic health and nutrition services, including infant and young child feeding counselling.
Experimenteel: Positive Deviance/Hearth (PDH) + SOC Group
PDH+SOC group, in addition to the SOC interventions, will receive 12 days of Hearth sessions (nutrition education) where caregivers of MAM children learn to cook and feed nutrient-dense meals using local ingredients they bring to the session. The caregivers will also hear six key contextualized messages developed through a formative research process prior to starting the Hearth sessions.
Ander: PD/Hearth is a behavioral change program that teaches caregivers how to cook and feed their children. A nutrient-dense meal using local ingredients will be fed to children during Hearth sessions.
PD/Hearth is a behavior change program that uses practice by doing approach for caregivers with children 6-59 months and empowers them to treat moderate acute malnutrition (MAM) at home using low cost local ingredients readily available. This makes it a much more sustainable approach in treating MAM children than specialized formulated foods, dietary supplements, or other processed foods.
