The impact of improvement of water supply and sanitation facilities on diarrhea and intestinal parasites: a Brazilian experience with children in two low-income urban communities
Open accessAbstract
During the second half of 1986 the impact of the improvement of water supply and excreta disposal facilities on diarrheal diseases and intestinal parasitosis was studied in 254 children up to six years of age from two favelas (shanty towns) of Belo Horizonte, Brazil. The estimated incidence of diarrhea was 6.2 episodes/child year and the estimated period prevalence reached 31.0 episode days/ child/ year. The point prevalence of parasitosis was 70.7% (Ascaris lumbricoides: 55.4%, Trichuris trichiura: 19.6%, Giardia lamblia: 17.9%). The estimated prevalence of diarrhea decreased with improvement of water supply and sanitation facilities to 45% and 44% respectively, but no statistically significant impact was observed in the case of parasitosis. School education and weaning practice were found to be other important determinants of diarrhea.

Gross 1989 was excluded because it had an ineligible study design (non-comparative cross-sectional survey; no pre-test measures or comparison groups to directly examine effect of upgrading).
“Gross 1989 Ineligible study design ‐ non‐comparative cross‐sectional survey. No pre‐test measures or comparison groups to directly examine effect of upgrading.”
From Slum upgrading strategies involving physical environment and infrastructure interventions and their effects on health and socio-economic outcomes (2013) · cites this paper as Gross 1989
The Sociocultural survey section describes a single inquiry using mothers’ reports of diarrhea during the preceding two weeks, and the Results compare these short-period estimates with longitudinal data; no pre-upgrade measurement is described. But calling the survey “non-comparative” overstates the point: the Results compare children in households with and without piped water or sanitation. Those are observational household comparisons, not a before-and-after test of upgrading. (LLM, conf=0.86)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
