Abstract
Access to safe drinking water and improved hygiene are essential for preventing diarrheal diseases in low- and middle-income countries. Integrating water treatment and hygiene products into antenatal clinic care can motivate water treatment and handwashing among pregnant women. Free water hygiene kits (water storage containers, sodium hypochlorite water treatment solution, and soap) and refills of water treatment solution and soap were integrated into antenatal care and delivery services in Machinga District, Malawi, resulting in improved water treatment and hygiene practices in the home and increased maternal health service use. To determine whether water treatment and hygiene practices diffused from maternal health program participants to friends and relatives households in the same communities, we assessed the practices of 106 nonpregnant friends and relatives of these new mothers at baseline and 1-year follow-up. At follow-up, friends and relatives were more likely than at baseline to have water treatment products observable in the home (33.3% vs. 1.2%, p < 0.00001) and detectable free chlorine residual in their water, confirming water treatment (35.7% vs. 1.4%; p < 0.00001). Qualitative data from in-depth interviews also suggested that program participants helped motivate adoption of water treatment and hygiene behaviors among their friends and relatives.
