Insubstantial Impact

Poor sanitation is linked to child mortality and stunted growth in low-income communities. WASH (water, sanitation and hygiene) interventions are implemented to improve child health outcomes but, until recently, their impact had not been evaluated.
 
A new study found that children in communities with WASH interventions were significantly healthier but not necessarily thriving, and that WASH alone was not enough—nutritional supplements in addition to WASH improvements made a greater impact.
 
“What this tells us is that these interventions ... likely didn’t clean the environment enough to impact child growth,” says epidemiologist Stephen Luby. “This is a disappointment, but it also helps to provide direction as a way forward.”
