This study supports SDGs 3 and 6 by showing that a handwashing intervention involving disgust-inducing messages, combined with the provision of handwashing stations in Abidjan, Côte d'Ivoire, successfully increased rates of handwashing with soap after toilet use. These findings demonstrate the effectiveness of combining health-based messaging with non-health-based messaging when implementing water, sanitation, and hygiene interventions.
Independent and combined effects of improved water, sanitation, and hygiene, and improved complementary feeding, on child stunting and anaemia in rural Zimbabwe: a cluster-randomised trial
The Lancet Global Health, Volume 7, January 2019
This study supports SDGs 3 and 6 by showing that elementary WASH interventions alone were insufficient in reducing the prevalence of stunting, anaemia, and diarrhoea in children in rural Zimbabwe; these findings call for greater investment into, and scale-up of, WASH programmes in rural settings, in order to achieve more meaningful improvements in child health outcomes.
