Prevalence of adenoid hypertrophy and nocturnal enuresis in primary school children in Istanbul, Turkey

SummaryObjectiveThe purpose of this study is to investigate the prevalence of an existing relationship between adenoid hypertrophy and nocturnal enuresis in primary school children.MethodsThe study was performed in four primary schools that were chosen randomly in Kartal, Istanbul. The children's parents were asked to fill out a questionnaire that included questions concerning the associated symptoms of adenoid hypertrophy and nocturnal enuresis. The interrelations between adenoid hypertrophy and nocturnal enuresis items were examined by X2 tests.ResultsThe study population consisted of 1132 (625 girls, 621 boys) primary school children between 5 and 14 years of age (mean 9.59 ± 2.60 years). The children were divided into three groups with 5–7 years old children in Group I (n = 232), 8–10 years old children in Group II (n = 506) and 11–14 years old children in Group III (n = 394). Of the 1132 distributed questionnaires, 1090 (87.4%) were filled in adequately and were accepted for evaluation. Prevalence of adenoid hypertrophy in school children was found to be 58 in Group I (27%), 94 in Group II (19.5%) and 78 in Group III (19.9%). Prevalence of nocturnal enuresis in school children was found to be 35 in Group I (15.1%), 51 in Group II (10.1%) and 18 in Group III (4.6%). No statistically significant association was present between adenoid hypertrophy and nocturnal enuresis in either Group I, II or III school children.ConclusionIn contrast to previous studies, our prevalence study did not find an association between adenoid hypertrophy and nocturnal enuresis. Thus, this prevalence study provides otolaryngologists new and interesting information.
