We assessed a pilot project by UNICEF and Hindustan Unilever Limited to improve the quality of drinking water for children in schools through adoption of improved drinking water practices among households in southern India. The intervention consisted of providing classrooms of 200 schools a commercial water purifier, and providing basic hygiene and water treatment information to students, parents, and teachers. We found no evidence that the intervention was effective in improving awareness or uptake of effective water treatment practices at home. A similar proportion of household members in the intervention and control groups boiled their water (P = 0.60), used a ceramic filtration system (P = 0.33), and used a cloth filter (P = 0.89). One year after the launch of the campaign, household ownership of the commercial purifier promoted at schools was higher in the intervention group (26%) than the control group (19%), but this difference was not statistically significant (P = 0.53).
我们评估了联合国儿童基金会和印度斯坦联合利华有限公司开展的一个试点项目，该项目旨在通过在印度南部家庭中采用改进的饮用水处理方式，提高学校儿童的饮用水质量。干预措施包括为200所学校的教室配备商用净水器，并向学生、家长和教师提供基本的卫生和水处理信息。我们没有发现证据表明该干预措施能有效提高家庭对有效水处理方式的认知或采用率。干预组和对照组中采用烧水方式的家庭成员比例相似（P = 0.60），使用陶瓷过滤系统的比例相似（P = 0.33），使用布质过滤器的比例也相似（P = 0.89）。活动开展一年后，干预组中学校推广的商用净水器的家庭拥有率（26%）高于对照组（19%），但这一差异无统计学意义（P = 0.53）。
