Abstract

Background: This study aimed to assess the effectiveness of interventions delivered by CHWs and their strategies for reducing stunting in LMICs.

Methods: We undertook a systematic review following PRISMA guidelines. The articles were selected from major electronic databases, reference lists and grey literature from 2016 and 2023.

Results: Seventeen articles were included in the final analysis from the initial 2,899 search results. CHW-led interventions significantly reduce stunting. Training and refresher courses enhanced outcomes, while challenges included inconsistent implementation and resource constraints. The variability in results underscores the need for multisectoral collaboration to maximize impact.

Conclusion: Our findings highlighted the significant role of CHW-led interventions in reducing stunting, emphasizing their potential as accessible and reliable resources for local communities.
