Evidence Mapping of Wasting Programs and Their Impact Along the Continuum of Care in Low- and Middle-Income Countries: A Rapid Review of the Research Evidence: Evidence Note

To guide future programming decisions and guidelines to address wasting, TNWA performed a rapid review of both the quantity and effectiveness of existing interventions and programs to address wasting. An evidence note summarizes the findings on what works and identifies research gaps along the continuum of care for wasting.

Key messages

  • Although research has been done on prevention and treatment of wasting, knowledge gaps remain regarding strategies to increase screening and referral to wasting treatment programs.
  • Lipid-based Nutrient Supplements and food supplementation interventions/programs are effective in the prevention of wasting.
  • Specially formulated foods have shown their efficacy in recovery from MAM (CSB++, RUSF or RUTF) and SAM (RUTF).
  • In SAM cases, facility-based management using WHO guidelines has proved more effective than any alternative treatment strategy to reduce mortality.
  • Prevention of wasting and management of wasting cases in children under six months remain poorly documented.
  • The quality of the evidence is low.
