Despite a tremendous decline in the burden of malaria through public health interventions, it is yet remains a critical parasitic health problem in Ethiopia. Insecticide-treated nets and indoor residual spray are considered as the most effective preventive interventions against malaria. This study intended to determine the role of health extension workers in influencing the relationship between vector control strategies and malaria prevalence in Ethiopia.
The study adopted a descriptive study based on panel data collected from 10 regions of Ethiopia from 2010 to 2018. The data collected were analyzed using STATA version 13.0. Structural equation modelling was used to assess the mediating effect of health extension workers in the relationship. Further, the random effect model was employed to investigate the direct relationship among the study variables.
We observed a strong mediating role of health extension workers to the relationship between strategic interventions and malaria prevalence, where the direct path is (β = 0.64, p < 0.05), and the indirect path (β = 0.72, p < 0.001) and (β = 0.98, p < 0.001) confirming the mediation condition to appear. Our analysis revealed that, insecticide-treated nets and indoor residual spray significantly impacts the malaria prevalence (β = 0.20, p < 0.05) and (β = 0.70, p < 0.001) respectively. Further, our analysis suggests that the cumulative effect of indoor residual spray and insecticide-treated mosquito nets have helped better avert malaria prevalence (β = 81.3%, P < 0.05). Moreover, the finding demonstrates the incremental rate of 30.2%, which is the indirect effect of the research [(β = 0.813) - (β1 = 0.511)].
The findings are potentially useful for the health sector in charge of infectious disease prevention and control, particularly in developing countries explaining how these group provided support to reduce malaria ensuring the provision of proper health message about the program.
尽管通过公共卫生干预措施，疟疾负担大幅下降，但在埃塞俄比亚，它仍然是一个严重的寄生虫健康问题。经杀虫剂处理的蚊帐和室内滞留喷洒被认为是预防疟疾最有效的干预措施。本研究旨在确定卫生推广工作者在影响控制策略与疟疾在埃塞俄比亚的流行之间的关系中的作用。
本研究采用描述性研究，基于 2010 年至 2018 年从埃塞俄比亚 10 个地区收集的面板数据。使用 STATA 版本 13.0 对收集的数据进行分析。结构方程模型用于评估卫生推广工作者在关系中的中介作用。此外，采用随机效应模型研究研究变量之间的直接关系。
我们观察到卫生推广工作者在战略干预措施与疟疾流行之间的关系中发挥了强大的中介作用，其中直接路径为（β=0.64，p<0.05），间接路径为（β=0.72，p<0.001）和（β=0.98，p<0.001），证实了中介条件的出现。我们的分析表明，经杀虫剂处理的蚊帐和室内滞留喷洒显著影响疟疾流行（β=0.20，p<0.05）和（β=0.70，p<0.001）。此外，我们的分析表明，室内滞留喷洒和经杀虫剂处理的蚊帐的累积效应有助于更好地避免疟疾流行（β=81.3%，P<0.05）。此外，研究结果表明，间接效应为 30.2%，即研究的间接效应[（β=0.813）-（β1=0.511）]。
这些发现对于负责传染病预防和控制的卫生部门可能是有用的，特别是在发展中国家，这些发现解释了这些群体如何提供支持以减少疟疾，确保提供有关该计划的适当健康信息。
