Promoting Handwashing Behavior: The Effects of Large‐scale Community and School‐level Interventions
分析秘鲁一项大规模社区和学校干预实验，发现干预提高了洗手知识和行为，但未改善5岁以下儿童健康。
This paper analyzes a randomized experiment that uses novel strategies to promote handwashing with soap at critical points in time in Peru. It evaluates a large-scale comprehensive initiative that involved both community and school activities in addition to communication campaigns. The analysis indicates that the initiative was successful in reaching the target audience and in increasing the treated population's knowledge about appropriate handwashing behavior. These improvements translated into higher self-reported and observed handwashing with soap at critical junctures. However, no significant improvements in the health of children under the age of 5 years were observed. Copyright © 2015 John Wiley & Sons, Ltd.
