We conducted a study in a squatter settlement in Karachi, Pakistan where residents report commonly washing their hands to determine if providing soap, encouraging hand washing, and improving wash-water quality would improve hand cleanliness. We allocated interventions to 75 mothers and collected hand-rinse samples on unannounced visits. In the final model compared with mothers who received no hand-washing intervention, mothers who received soap would be expected to have 65% fewer thermotolerant coliform bacteria on their hands (95% CI 40%, 79%) and mothers who received soap, a safe water storage vessel, hypochlorite for water treatment, and instructions to wash their hands with soap and chlorinated water would be expected to have 74% fewer (95% CI 57%, 84%). The difference between those who received soap alone, and those who received soap plus the safe water vessel was not significant (P = 0.26). Providing soap and promoting hand washing measurably improved mothers' hand cleanliness even when used with contaminated water.
我们在巴基斯坦卡拉奇的一个棚户区开展了一项研究，该棚户区的居民称经常洗手，我们旨在确定提供肥皂、鼓励洗手以及改善洗水质量是否会提高手部清洁程度。我们将干预措施分配给75位母亲，并在未事先通知的情况下采集她们的手冲洗样本。在最终模型中，与未接受洗手干预的母亲相比，接受肥皂的母亲手上的耐热大肠菌群预计会减少65%（95%置信区间为40%，79%），而接受肥皂、一个安全储水容器、用于水处理的次氯酸盐以及用肥皂和加氯水洗手的指导的母亲手上的耐热大肠菌群预计会减少74%（95%置信区间为57%，84%）。仅接受肥皂的母亲与接受肥皂加安全储水容器的母亲之间的差异不显著（P = 0.26）。即使使用受污染的水，提供肥皂并促进洗手也能显著提高母亲的手部清洁程度。
