Long-Term Effects of Community Health Worker Training on Malaria Education and Prevention Among Rural Kenyan Women
Malaria remains a significant public health challenge in rural Kenya, where community health workers (CHWs) play a crucial role in education and prevention efforts. A comprehensive search strategy was employed using multiple databases, with inclusion criteria based on study design, participant demographics, and intervention specifics. The review identified a consistent trend indicating that CHW interventions led to improved knowledge about malaria in over 80% of the participants after one year of training. CHW training appears effective in enhancing malaria prevention practices among rural Kenyan women, though long-term adherence and sustainability require further investigation. Future research should focus on evaluating the impact of CHW-led interventions over longer periods and explore strategies for maintaining these effects. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.

Time-Series Forecasting Model for Cost-Effectiveness Evaluation of Public Health Surveillance Systems in Ghana,
Public health surveillance systems in Ghana have been established to monitor infectious diseases and track their impact on public health. However, there is a need for robust methods to evaluate the cost-effectiveness of these systems over time. A time-series forecasting model was employed using a SARIMA (Seasonal AutoRegressive Integrated Moving Average) approach. Uncertainty in predictions was quantified through robust standard errors, ensuring reliable cost-effectiveness estimates. The model predicted an annual reduction of approximately 15% in the prevalence of infectious diseases over the study period, with a 95% confidence interval indicating substantial stability in system performance. The time-series forecasting model demonstrated promising results for evaluating public health surveillance systems in Ghana. The findings suggest that the current system is cost-effective and can be scaled up without compromising its efficiency. Public health authorities should consider implementing this model to forecast future trends and inform resource allocation decisions, thereby enhancing the effectiveness of surveillance systems. time-series forecasting, public health surveillance, cost-effectiveness, Ghana Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
Assessment of Gender-Based Violence Prevention Programmes Among Male and Female Teachers in South African Schools
Gender-based violence (GBV) prevention programmes are essential in educational settings to promote a safe learning environment for all students, including teachers of both genders. The study employed a mixed-method approach involving surveys and focus group discussions to gather data from 150 male and 150 female teachers across 20 randomly selected schools. Quantitative analysis was conducted using SPSS version 26, with confidence intervals for statistical significance considered. A notable theme emerged regarding the efficacy of peer mentoring programmes in reducing GBV incidents among teachers; these interventions showed a significant reduction in reported conflicts (p ≤ 0.05) compared to pre-intervention levels. The findings suggest that comprehensive GBV prevention programmes can significantly improve conflict resolution and mental health outcomes for both male and female teachers, contributing positively to the school environment. School administrators should prioritise the implementation of multi-faceted GBV prevention strategies, including peer mentoring programmes, as a means of fostering safer educational environments.

Methodological Evaluation of Public Health Surveillance Systems in Nigeria Using Difference-in-Differences Models for Clinical Outcomes Analysis
Public health surveillance systems in Nigeria are crucial for monitoring disease outbreaks and tracking clinical outcomes. However, their effectiveness can vary significantly across different regions. We employed a DiD model, a quasi-experimental design that compares treated and untreated groups over time. Our analysis focuses on two regions: Region A with active surveillance systems and Region B without such systems. The model accounts for potential confounders using robust standard errors to ensure the validity of our findings. In Region A, where public health surveillance systems were operational, we observed a significant reduction in hospitalization rates by 20% (95% CI: -30%, -10%) compared to Region B. This suggests that active surveillance can lead to better clinical outcomes and reduced morbidity. Our study provides evidence supporting the efficacy of public health surveillance systems in Nigeria, particularly for monitoring and mitigating disease impacts on hospitalization rates. The DiD model allows us to make robust inferences about the impact of these systems without relying on randomized controlled trials. Based on our findings, we recommend strengthening surveillance infrastructure in regions where they are not currently operational or ensuring that existing systems are adequately funded and staffed to maintain their effectiveness.
