A community survey of enuresis was carried out in November/December 2002 among 300 apparently healthy children aged 5-16 years selected systematically from the Ehor Local Government Area in Edo State, Nigeria. This was done with the aim of ascertaining the true prevalence of the disease and the contributions of some organic causative factors. The overall prevalence of enuresis was 21.3%. Of the 64 children who were enuretic, 58 (91%) had only nocturnal enuresis. No strict daytime enuresis was recorded. Combined daytime and night time enuresis accounted for only six (9.4%) cases. Ninety-four percent of cases of enuresis were primary, while only six were secondary. Prevalence of enuresis declined significantly with increasing age (chi2= 14 .93, df= 3; p = 002). There was a strong association between enuresis and family history of bed wetting (more so with siblings) (chi2 = 45.09, p < 0.000). Though not statistically significant, enuresis was more common in males, in children drawn from families of poor socio-economic status, among first order births, and among those with asymptomatic bacteriuria. Also, there was no significant association between enuresis and hemoglobin genotype. Organic conditions played a minimal role in the etiology of enuresis in the study location, but the morbidity occurred frequently enough to warrant health attention. A community approach is advocated because only an insignificant proportion is seen in orthodox health facilities.
