Background Childhood diarrhoea is a leading cause of morbidity and mortality in Nicaragua.
Amongst the risk factors for its transmission are'poor'hygiene practices.
We investigated the effect of a large number of hygiene practices on diarrhoeal disease in children aged<2 years and validated the technique of direct observation of hygiene behaviour.
Methods A prospective follow-up study was carried out in a rural zone of Nicaragua.
From the database of a previously conducted case-control study on water and sanitation 172 families were recruited, half of which had experienced a higher than expected rate of diarrhoea in their children and the other half a lower rate.
Hygiene behaviour was observed over two mornings and diarrhoea incidence was recorded with a calendar, filled out by the mother, and collected every week for 5 months.
Results Of 46'good'practices studied, 39 were associated with a lower risk of diarrhoea, five were unrelated and only for two a higher risk was observed.
Washing of hands, domestic cleanliness (kitchen, living room, yard) and the use of a diaper/underclothes by the child had the strongest protective effect.
Schooling (>3 years of primary school) and better economic position (possession of a radio) had a positive influence on general hygiene behaviour, education having a slightly stronger effect when a radio was present. (...)
