Childhood diarrhoea and observed hygiene behaviour in Salvador, Brazil.

Using structured observation, researchers scored behaviour as either hygienic or unhygienic. Among children with mainly positive hygiene behaviour, the prevalence of diarrhoea was 6.4days/child year, compared with 14.2days/child year for children with mainly unhygienic behaviour (highly significant difference). There was a significant association between a positive hygiene score and the presence of adequate excreta disposal facilitates in the home. The authors concluded that families predisposed to acquire adequate sanitation in their homes have a measurably better awareness of hygiene, which is expressed in their behaviour. The study data is indicative of the important role of hygiene behaviour, as well as water supply and sanitation facilities.Am J Epidemiol 2003;157:1032-1038.
