DESCRIPTION (provided by applicant): Diarrhea is the second leading cause of death among children less than five years old, causing about 2 million deaths annually. A meta-analysis of studies on handwashing with soap from low-, middle-, and high-income countries estimated a summary diarrhea risk reduction of 47%. Despite the proven health benefits of handwashing, data from numerous settings confirm that individuals do not practice good hand hygiene at the appropriate times. It is critical to identify which individual-level factors are conducive to adoption of improved hand hygiene in response to handwashing promotion. We hypothesize those mothers with acutely ill children will have heightened perceptions of disease risk and will, therefore, show greater receptivity to a message encouraging handwashing behavior as a disease risk reduction strategy. Therefore, we propose to examine whether mothers whose children are currently suffering from diarrhea are more likely to improve handwashing behavior following a handwashing promotion intervention than are mothers of children who are currently well. To achieve this specific aim, we will conduct a 2x2 factorial randomized controlled trial in New Delhi, India in which we will enroll 400 households of children < 2 years old. Of these, 200 will be households of children with acute diarrhea and 200 will be households of children who are well. From each group, we will assign 100 households to intensive handwashing promotion and 100 households to continue their usual hand hygiene practices (control). We will measure handwashing behavior during the acute diarrhea episode and again several weeks following resolution of the diarrhea using an innovative method consisting of motion sensors embedded in soap, which provide information on the number of times soap is used in the time period of interest without having a human observer present. The soap with motion sensor provides an objective measure of soap use and overcomes the reactivity that has been shown to occur in response to the presence of a human observer of handwashing behavior. In addition to this methodological innovation, the proposed study is conceptually novel. There is no information from published randomized controlled trials about whether risk perception is a motivating factor for the adoption of improved handwashing behavior. Such information will substantively inform future research on the decision-making processes involved in good hand hygiene and guide handwashing promotion programs in resource-poor countries where handwashing with soap at scale promises to reduce substantially the morbidity and mortality from diarrhea. PUBLIC HEALTH RELEVANCE: When mothers and other household members improve handwashing with soap, children suffer substantially fewer episodes of diarrhea, which is the second leading cause of death of young children worldwide. This innovative project aims to assess whether mothers of ill children are more likely to improve hand washing behavior compared to mothers of well children. Results from this study will be useful for international and civil society organizations worldwide that are trying to reduce the two million deaths from diarrhea occurring each year.

描述（由申请人提供）：腹泻是五岁以下儿童死亡的第二大原因，每年造成约200万人死亡。对低收入、中等收入和高收入国家用肥皂洗手的研究进行的荟萃分析估计，腹泻风险降低了47%。尽管洗手对健康有益，但来自许多环境的数据证实，人们没有在适当的时候保持良好的手部卫生。关键是要确定哪些个人层面的因素有利于通过改善手卫生，以促进洗手。我们假设，那些患有急性疾病的孩子的母亲会对疾病风险有更高的认识，因此，会对鼓励洗手行为作为降低疾病风险策略的信息表现出更大的接受性。因此，我们建议检查是否母亲的孩子目前患有腹泻更有可能改善洗手行为后，洗手促进干预比母亲的孩子谁是目前很好。为了实现这一特定目标，我们将在印度新德里进行一项2x2析因随机对照试验，我们将招募400个2岁以下儿童家庭。其中，200户将是患有急性腹泻的儿童家庭，200户将是健康儿童家庭。我们将从每组中分配100个家庭进行深入的洗手宣传，并分配100个家庭继续他们的日常手部卫生习惯（对照组）。我们将在急性腹泻发作期间测量洗手行为，并在腹泻消退后数周再次使用由嵌入肥皂中的运动传感器组成的创新方法，该方法提供有关在感兴趣的时间段内使用肥皂的次数的信息，而无需人类观察者在场。具有运动传感器的肥皂提供了肥皂使用的客观测量，并且克服了已经显示的响应于洗手行为的人类观察者的存在而发生的反应性。除了这种方法上的创新，拟议的研究是概念新颖。从已发表的随机对照试验中没有关于风险感知是否是采用改进洗手行为的激励因素的信息。这些信息将为未来关于良好手部卫生决策过程的研究提供实质性信息，并指导资源贫乏国家的洗手推广计划，在这些国家，大规模用肥皂洗手有望大幅降低腹泻的发病率和死亡率。 公共卫生关系：当母亲和其他家庭成员改进用肥皂洗手时，儿童患腹泻的次数大大减少，腹泻是全球幼儿死亡的第二大原因。这个创新项目旨在评估与健康儿童的母亲相比，生病儿童的母亲是否更有可能改善洗手行为。这项研究的结果将对世界各地的国际和民间社会组织有用，这些组织正在努力减少每年因腹泻而死亡的200万人。
