Safe water storage and hand hygiene have been shown to reduce fecal contamination and improve health in experimental settings; however, triggering and sustaining such behaviors is challenging. This study investigates the extent to which personalized information about Escherichia coli contamination of stored water and hands influenced knowledge, reported behaviors, and subsequent contamination levels among 334 households with less than 5-year-old children in peri-urban Dar es Salaam, Tanzania. One-quarter of the study participants received information about strategies to reduce risk of water- and sanitation-related illness. Respondents in another three study cohorts received this same information, along with their household's water and/or hand-rinse test results. Findings from this study suggest that additional work is needed to elucidate the conditions under which such testing represents a cost-effective strategy to motivate improved household water management and hand hygiene.
安全储水和手部卫生已被证明可以减少粪便污染并改善实验环境中的健康状况；然而，触发和维持这些行为是具有挑战性的。本研究调查了在坦桑尼亚达累斯萨拉姆郊区，针对 334 户家中有 5 岁以下儿童的家庭，有关储存水和手部大肠杆菌污染的个性化信息对知识、报告行为以及随后的污染水平的影响程度。研究的四分之一参与者收到了有关减少与水和卫生相关疾病风险的策略的信息。另外三个研究队列的参与者也收到了相同的信息，以及他们家庭的水和/或手部冲洗测试结果。本研究的结果表明，需要进一步研究，以阐明在何种条件下，这种测试可以成为一种具有成本效益的策略，以激励改善家庭用水管理和手部卫生。
