Randomized trials
Did India’s toilet campaign improve child health?
Open access · cc by · source: Europe PMC
A village-randomized sanitation program raised latrine access and cut open defecation modestly but did not improve child diarrhea, parasites, anemia, or growth.
How this study connects
Role on claims
Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.
Multiple studies in this library examine randomized trials with empirical patient or population outcomes rather than opinion alone.
Evidence for the claim as stated.
Intervention villages gained about 19 percentage points in improved sanitation facilities and a smaller (~10%) reduction in open defecation, but child health endpoints did not improve.
Evidence for the claim as stated.
Effect sizes and settings differ across randomized trials studies — digital vs clinic, trial vs observational — so results should not be pooled casually.
Evidence for the claim as stated.
India's Total Sanitation Campaign was cluster-randomised across 80 villages in rural Madhya Pradesh. Intervention villages gained about 19 percentage points in improved sanitation facilities and a smaller (~10%) reduction in open defecation, but child-health endpoints did not improve after about 21 months. Short follow-up and some control-group contamination mean the trial shows this scaled package did not move health markers here, not that sanitation can never help.
Evidence for the claim as stated.
Process success and health success are not the same cluster-trial result. TSC moved toilets (~19 percentage points) without moving child health; TB medication monitors moved adherence 40–50% without, in this report, proving cure; SASA! moved IPV and concurrency by about 50% as the intended social outcome. A student who treats 'the cluster intervention worked' as one sentence will misread at least one of these papers.

Sanitation facilities +19% and open defecation −10%, without child health gains
While the TSC program in rural Madhya Pradesh implemented with support from the WSP increased the household level availability of JMP defined sanitation facilities (+19%) and to a lesser extent reduced open defecation (−10%), these improvements were insufficient to improve child health outcomes (diarrhea, parasite infections, anemia, growth).
Baseline sample 3,390 children <5 from 80 villages
The baseline survey enrolled a sample of 3,390 children <5 years from 1,954 households from 80 villages.
Key findings
Intervention villages gained about 19 percentage points in improved sanitation facilities and a smaller (~10%) reduction in open defecation, but child health endpoints did not improve.
Methodology
Investigators cluster-randomized 80 villages in rural Madhya Pradesh to India’s Total Sanitation Campaign support versus control, surveying thousands of children under five at baseline and about 21 months later for sanitation behaviours and health outcomes.
Limitations
Short follow-up and some control-group contamination mean the trial cannot prove sanitation never helps—only that this scaled TSC package did not move health markers enough here.
