TL;DR: While studies to date provide some support for positive effects from sanitation on cognitive development, the effects on school absence are uncertain and further research in multiple settings using rigorous study designs and measuring intermediate outcomes such as exposure can help determine the effects of sanitation on these important learning outcomes.

TL;DR: Repeated weight-for-age z-score measures appear to be a suitable proxy marker for diarrhoea in children, but have disadvantages in terms of specificity and study power.

TL;DR: Mokken scaling techniques were applied to series of population-based surveys in Odisha, India between September 2011 and October 2013 and produced two scales, reflecting attitudes toward defecation and norms regarding latrine use for all respondents and personal experiences with and perceived convenience of sanitation technologies targeted at respondents with a latrine.

TL;DR: To achieve open defecation free communities, sanitation interventions will need to develop behaviour change approaches to explicitly target safe disposal behaviours.

TL;DR: The Kato-Katz technique gave the best overall diagnostic performance with the highest results in all measures (prevalence, faecal egg count, sensitivity) followed by the conventional ethyl-acetate and then the Midi Parasep(®) technique.
