However, these interactions are poorly understood. The purpose of this study was to characterize how school and home WaSH exposures were associated with <jats:italic>Ascaris lumbricoides<\/jats:italic> infection and to identify relevant interactions between separate WaSH technologies and behaviors. A study was conducted among 4,404 children attending 51 primary schools in western Kenya. We used multivariable mixed effects logistic regression to characterize how various WaSH exposures were associated with <jats:italic>A. lumbricoides<\/jats:italic> infection after annual school-based deworming. Few WaSH behaviors and technologies were independently associated with <jats:italic>A. lumbricoides<\/jats:italic> infection. However, by considering relevant interdependencies between variables, important associations were elucidated. The association between handwashing and <jats:italic>A. lumbricoides<\/jats:italic> depended largely upon the pupils' access to an improved water source. Among pupils who had access to improved water sources, <jats:italic>A. lumbricoides<\/jats:italic> prevalence was lower for those who handwashed both at school and home compared with neither place (odds ratio: 0.38, 95% confidence interval: 0.18\u20130.83; <jats:italic>P<\/jats:italic> = 0.01). This study contributes to a further understanding of the impact of WaSH on <jats:italic>A. lumbricoides<\/jats:italic> infection and shows the importance of accounting for interactions between WaSH technologies and behaviors.<\/jats:p>","DOI":"10.4269\/ajtmh.15-0362","type":"journal-article","created":{"date-parts":[[2016,2,23]],"date-time":"2016-02-23T03:43:42Z","timestamp":1456199022000},"page":"1045-1054","source":"Crossref","is-referenced-by-count":11,"title":["Ascaris
