Objective: The purpose of this study was to analyze the different pathogenic factors in a large population of children.
Patients and 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.
