Community Health Worker Programmes for Malaria Prevention and Treatment in Northern Mozambique: A Three-Month Impact Evaluation Meta-Analysis

Malaria remains a significant public health issue in northern Mozambique, where community health worker (CHW) programmes are implemented to improve access to malaria prevention and treatment. A comprehensive literature search was conducted using databases relevant to public health, including PubMed and Web of Science. Studies were included if they met specific criteria for design consistency and measurable outcomes related to malaria prevention and treatment. CHW programmes demonstrated a statistically significant reduction in malaria cases (p < 0.05) with an odds ratio of 0.72 (95% CI: 0.61-0.84). The analysis supports the effectiveness of CHW interventions for malaria control, offering insights into programme implementation and scaling. Further research should investigate long-term sustainability and cost-effectiveness of these programmes in rural settings. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
