We assessed whether supplying soap to primary schools on a regular basis increased pupil hand washing and decreased Escherichia coli hand contamination. Multiple rounds of structured observations of hand washing events after latrine use were conducted in 60 Kenyan schools, and hand rinse samples were collected one time in a subset of schools. The proportion of pupils observed practicing hand washing with soap (HWWS) events was significantly higher in schools that received a soap provision intervention (32%) and schools that received soap and latrine cleaning materials (38%) compared with controls (3%). Girls and boys had similar hand washing rates. There were non-significant reductions in E. coli contamination among intervention school pupils compared with controls. Removing the barrier of soap procurement can significantly increase availability of soap and hand washing among pupils; however, we discuss limitations in the enabling policy and institutional environment that may have prevented reaching desired levels of HWWS.
我们评估了定期向小学供应肥皂是否会增加学生洗手的次数并减少大肠杆菌对手的污染。在肯尼亚的 60 所学校中，我们对使用厕所后的洗手事件进行了多轮结构化观察，并在一组学校中收集了一次手部冲洗样本。与对照组（3%）相比，接受肥皂供应干预的学校（32%）和接受肥皂和厕所清洁材料的学校（38%）中，观察到的学生用肥皂洗手（HWWS）事件的比例明显更高。女孩和男孩的洗手率相似。与对照组相比，干预学校的学生大肠杆菌污染的比例有一定程度的降低，但没有显著差异。消除肥皂采购的障碍可以显著增加学生获得肥皂和洗手的机会；然而，我们讨论了在政策和制度环境方面的限制因素，这些因素可能阻碍了学生达到理想的 HWWS 水平。
