title: Epidemiology of nocturnal enuresis in basic schoolchildren in Aden Governorate, Yemen.
abstract: Nocturnal enuresis is a common problem among children and adolescents. Data regarding this problem in schoolchildren in Yemen are scarce. This study was aimed to determine the prevalence of nocturnal incontinence in Aden school going children, describe its severity and identify the relation between nocturnal enuresis with personal and family characteristics. The study was a cross-sectional survey conducted on the public basic schoolchildren in Aden, Yemen, in the period November 2007-April 2009. A random, multistage sample of 890 students was taken from four districts in eight schools and divided into two strata: males and females. Data were obtained by using pre-recorded questionnaire, which was completed by parents. The response rate was 73.7% (656 students); 113 (17.2%) cases of nocturnal enuresis were encountered. Nocturnal enuresis decreased by age from 31.5% at 6-8 years to 8.7% at 15+ years (P < 0.05). Primary nocturnal enuresis affected 76.1%, of which the majority of children were bedwetting every night. Positive family history of nocturnal enuresis, deeper sleep, daytime enuresis, tea drinking, being non working father or with less education showed significant association with the occurrence of enuresis in the students. Stressful events in the previous 6 months of the study were twice more frequently noted. The study concluded that the prevalence of nocturnal enuresis in Aden public school children and its associated factors are almost comparable with that reported in epidemiological studies from various countries. Health education will encourage the parents to be aware, cope with this problem and seek appropriate medical advice.
