Title: Sanitation, Hygiene, Infant Nutrition Efficacy Project
Brief Summary: Globally, stunting affects 26% (165 million) of under-5-year children, underlies 15-17% of their mortality and leads to long-term cognitive deficits, fewer years and poorer performance in school, lower adult economic productivity, and a higher risk that their own children will also be stunted, perpetuating the problem into future generations. Stunting begins antenatally and peaks at 18-24 months of postnatal life, when mean length-for-age Z-score (LAZ) is about -2.0 among children living in Africa and Asia. Improving the diets of young children can reduce stunting, though, at best, only by about one-third. Frequent diarrheal illness has also been implicated. However, the effect of diarrhea on permanent stunting is relatively small, maybe because children grow at "catch-up" rates between illness episodes.

The Sanitation Hygiene Infant Nutrition Efficacy (SHINE) trial is motivated by a 2-part premise:

* A major cause of child stunting and anemia is Environmental Enteric Dysfunction (EED). EED is a subclinical disorder of the small intestine, which is virtually ubiquitous among asymptomatic people living in low-income settings throughout the world. EED is characterized by increased permeability which facilitates microbial translocation into the systemic circulation and triggers chronic immune activation.
* The primary cause of EED is infant ingestion of fecal microbes due to living in conditions of poor quality and quantity of water, sanitation, and hygiene (WASH).
