[Epidemiological study of nocturnal enuresis: analysis of associated factors].
OBJECTIVE
The purpose of this study was to analyze the different pathogenic factors in a large population of children.


METHODS
A transverse epidemiological study was performed. Schoolchildren in the province of Leon between 6 and 10 years of age were studied during the 1991-1992 academic year. A randomly chosen sample of 2,165 children was used. The study was carried out by means of an anonymous survey given to the children's parents by the school.


RESULTS
In addition to family antecedents of enuresis, the main associated factors were the mother's cultural status, with enuresis more frequent if the status was low, and the child's birth order.


CONCLUSIONS
This study shows that certain family conditions favor the development of nocturnal enuresis.
