Due to a high burden imposed on public health from malaria disease in Sub-Saharan Africa, the vector control strategy is a significant concern. Despite the implementation of malaria control interventions in Ethiopia, it remains a major public health problem. Moreover, none of the prior researches was conducted in this title specifically. Therefore, this study investigates the impact of vector control interventions on malaria based on panel data of 10 malaria endemic-regions from 2000 to 2018.
A reflexive analysis study based on before-and-after assessment was used to evaluate the impact of vector control interventions on malaria with a difference-in-difference approach, representing Period I for before and Period II for after strategic intervention. The random-effect model was also employed to explore the direct relationship between the study variables. The data exported to Stata version 13.0 for analysis.
The study results suggest that the negative relationship between intervention strategy and malaria cases reported in comparison with its counterfactual, showing the increase in malaria cases during Period II comparing to Period I. The study explores a remarkable achievement on the decline in mean malaria-related death in all regions after the implementation of the strategy. Furthermore, a significant relationship between indoor residual spraying, insecticide-treated mosquito nets, and malaria was demonstrated within the strategic periods.
Better results achieved in Period I on mean malaria cases. The results of Period II showed a decline in mean malaria related-death, which was encouraging. The study calls for a supplementary strategy to align with the existing program. The study demonstrates the need for extra efforts on the implementation of the programme and progress about malaria.
由于撒哈拉以南非洲疟疾给公共卫生带来的沉重负担，病媒控制策略是一个重要关注点。尽管在埃塞俄比亚实施了疟疾控制干预措施，但它仍然是一个主要的公共卫生问题。此外，之前没有任何研究专门针对这一主题进行。因此，本研究基于 2000 年至 2018 年来自 10 个疟疾流行地区的面板数据，调查了病媒控制干预措施对疟疾的影响。
本研究采用前后评估的反思性分析方法，采用差异法评估病媒控制干预措施对疟疾的影响，代表战略干预前的第一时期和后一时期。还采用随机效应模型来探索研究变量之间的直接关系。数据导出到 Stata 版本 13.0 进行分析。
研究结果表明，干预策略与报告的疟疾病例之间存在负相关关系，与反事实相比，战略干预后的第二时期疟疾病例增加。研究还探索了在实施该战略后所有地区与疟疾相关的死亡人数平均下降的显著成就。此外，在战略时期内还发现了室内滞留喷洒、经杀虫剂处理的蚊帐与疟疾之间的显著关系。
第一时期在平均疟疾病例方面取得了更好的结果。第二时期的结果显示，与疟疾相关的死亡人数平均下降，这令人鼓舞。本研究呼吁采取补充战略与现有计划保持一致。该研究表明需要在方案实施和疟疾进展方面做出额外努力。
