Children in Poverty and Public Health : An Economic Analysis of Parasite Infection in Bangladesh

利用孟加拉国农村随机对照卫生干预项目的现有数据，在项目周期期间和项目完成后立即看到了提供驱虫药的效果。关于健康教育的影响，虽然事实证明，健康教育在提高人们对健康和卫生问题的知识和认识方面是有效的，但在项目完成后，这种获得的知识被发现相对较快地消失了。至于成本效益，正如以往的研究所知，与提供健康教育相比，提供驱虫药是非常具成本效益的。然而，这些结果也取决于提供健康教育的方式，不应将其全部视为不必要的东西。还需要找出提供健康教育的适当方法，以实现可持续的健康改善。

The effectiveness of the provision of deworming drug was seen both during the project cycle and right after the project completion, using available data on a randomized-controlled health intervention project in rural Bangladesh. Regarding the impact of health education, while it has proven to be effective in raising people's knowledge and awareness for health and sanitation issues, such acquired knowledge was found to disappear relatively quickly after the project completion. As for cost-effectiveness, as it was already known from previous studies, the provision of deworming drug was highly cost-effective compared to the provision of health education. Nonetheless, such results also depend on the way in which health education is delivered, and it should not be all together regarded as something unnecessary. There is yet a need for discerning appropriate methods of delivering health education in order to achieve sustainable health improvement.
