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).


Options:
A: Inclusion Criteria:

* All people above 18 years of age.

Exclusion Criteria:

-
B: Study participants will be women who are rural residents of Chirumanzu or Shurugwi districts in Zimbabwe and who become pregnant during the enrollment period of the trial and are identified and consent to participation during pregnancy, and their live born infants. A total of 5280 women will be enrolled.

Inclusion Criteria:

Pregnant women residing in the study districts, whose pregnancy is confirmed by a urine pregnancy test.

Exclusion Criteria:

* Women residing in the study districts who become pregnant during the enrollment period but do not consent to join the trial
* Women who reside in urban areas of these two districts
* Infants with major non-fatal abnormalities will not be excluded from study procedures, but will be excluded from the final analytic sample if the abnormality is likely to directly affect gut health/function or stature (e.g. neural tube defects, cerebral palsy, Down syndrome)
C: Inclusion Criteria:

* Villages located in rural Mali.
* CLTS targets small villages (less than 4500 inhabitants).
* Open defecation is present

Exclution criteria:

-Villages where CLTS is already in place
D: Inclusion Criteria:

-All households with children under 5 years in the study communities are eligible for socio-economic and health outcome evaluation.

Exclusion Criteria:

-All households are eligible to participate in the intervention. However, for the purposes of the study, households with no children under the age of 5 will not be selected for data collection purposes.
