Effects of water quality, sanitation, handwashing, and nutritional interventions on diarrhoea and child growth in rural Kenya: a cluster-randomised controlled trial

Poor nutrition and exposure to faecal contamination are associated with diarrhoea and growth faltering, both of which have long-term consequences for child health. This trial aimed to assess whether water, sanitation, handwashing, and nutrition interventions reduced diarrhoea or growth faltering.

Effects of water quality, sanitation, handwashing, and nutritional interventions on diarrhoea and child growth in rural Bangladesh: a cluster randomised controlled trial

Diarrhoea and growth faltering in early childhood are associated with subsequent adverse outcomes. This trial aimed to assess whether water quality, sanitation, and handwashing interventions alone or combined with nutrition interventions reduced diarrhoea or growth faltering. Overall the trial found that nutrient counselling and supplementation modestly improved linear growth, but that there was no benefit to the integration of water, sanitation, and handwashing with nutrition.

Exploring Determinants of Handwashing with Soap in Indonesia: A Quantitative Analysis

Handwashing with soap is recognized as a cost-effective intervention to reduce morbidity and mortality associated with enteric and respiratory infections. This study analyzes rural Indonesian households’ hygiene behaviors and attitudes to examine how motivations for handwashing, locations of handwashing space in the household, and handwashing moments are associated with handwashing with soap as potential determinants of the behavior. The analysis was conducted using results from a UNICEF cross-sectional study of 1700 households in six districts across three provinces of Indonesia.

Mass Behaviour Change Campaigns: what works and what doesn't

The promotion of hygienic behaviour – and particularly handwashing with soap – is one of the most cost-effective health interventions. Yet, despite bringing some of the highest public health returns on investments, hygiene is neglected – in public health interventions, in national and global health policy priorities, and in national and global monitoring frameworks.

Promoting handwashing and sanitation behaviour change in low-and middle-income countries

This report by 3ie summarises a systematic review by De Buck and colleagues that examines which promotional approaches are effective in changing handwashing and sanitation behaviour and which implementation factors affect the success or failure of such interventions. The study is the first mixed methods systematic review of behaviour change in sanitation and hygiene, drawing on quantitative and qualitative evidence. It shows that CLTS, in comparison with approaches like social marketing and health messaging, is most effective in improving OD behaviour and latrine use.

Norms, nudges, or addiction? Understanding drivers for handwashing behavior change.

Handwashing with soap is one of the most effective ways to prevent diseases, but behavior change to increase handwashing remains a challenge. On September 12, 2017, the Global Handwashing Partnership and USAID hosted a webinar that focused on behavior change approaches for handwashing with soap. The webinar gave participants ideas and perspectives to use on Global Handwashing Day and throughout the year.

SOAPEN: could this soap crayon help prevent child deaths?

According to UNICEF, diarrhea is deadly for 1.5 million children under the age of 5 every year. Sanitation, handwashing and hygiene are crucial elements in preventing these deaths. But how can children get into the habit of washing their hands? This is exactly the problem that a group of Indian industrial designers from the Parson’s School of Design in New York City sought to solve when they designed SoaPen, a colored marker with ink that turns into soapy lather.


Habit Formation and Rational Addiction: A Field Experiment in Handwashing

Regular handwashing with soap is believed to have substantial impacts on child health in the developing world. Most handwashing campaigns have failed, however, to establish and maintain a regular practice of handwashing. Motivated by scholarship that suggests handwashing is habitual, This study designed, implemented and analyzed a randomized field experiment aimed to test the main predictions of the rational addiction model. To reliably measure handwashing, the researchers developed and produced a novel soap dispenser, within which a time-stamped sensor is embedded.

Handwashing in 51 Countries: Analysis of Proxy Measures of Handwashing Behavior

In 2009, a common set of questions addressing handwashing behavior was introduced into nationally representative Demographic and Health Surveys (DHS) and Multiple Indicator Cluster Surveys (MICS), providing large amounts of comparable data from numerous countries worldwide. The objective of this analysis is to describe global handwashing patterns using two proxy indicators for handwashing behavior from 51 DHS and MICS surveys conducted in 2010–2013: availability of soap anywhere in the dwelling and access to a handwashing place with soap and water.
