Training Programmes for Community Health Workers and Their Impact on Reducing HIV/AIDS Stigma in Kenya: A Longitudinal Review

HIV/AIDS remains a significant public health challenge in Kenya, where stigma associated with the disease continues to hinder effective prevention and treatment efforts. A systematic literature search was conducted using databases such as PubMed, Google Scholar, and African Journals Online. Studies published between and were included if they evaluated training programmes for CHWs in Kenya related to HIV/AIDS stigma reduction. Inclusion criteria focused on longitudinal studies with measurable outcomes. Longitudinal monitoring of the training programmes indicated that participants demonstrated significant improvement in attitudes towards individuals living with HIV (HIV+) over a period of one year, with an average increase of 30% in positive perceptions. The review found that structured CHW training significantly reduced HIV/AIDS stigma in Kenya. Key themes identified included the role of community engagement and peer support groups in fostering understanding and empathy towards HIV+ individuals. Future research should focus on replicating successful models, particularly those incorporating elements such as community-based interventions and ongoing support systems. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
