Association among nocturnal enuresis, body weight and obstructive sleep apnea in children of south Italy: an observational study.

Background: To evaluate the rate of nocturnal enuresis (NE), body weight and obstructive sleep apnea in children 5 to 10 years of age in South Italy and the possible association among these disorders.
Methods: We have administered 1100 validated questionnaires, in Italian language, to parents and we have analyzed data with a logistic regression.
Results: Forty-two percent of children had a BMI≥85th (group 1) vs 58.0% normal weight children at the same age (group 2). There is a higher number of overweight males compared to females without statistically differences. In group 1 there was a higher number of children with NE and obstructive sleep disorders and some children present with the association among these three disorders.
Conclusions: There are no statistically differences between two study groups for the association body weight-NE, body weight-NE-obstructive sleep disorders.
