The Prevalence of Nocturnal Enuresis in Bangkok, Thailand: A Descriptive and Questionnaire Survey of 5 to 15 Year-Old School Students

Objectives. Nocturnal enuresis (NE) is a common problem among school-aged children. Nonetheless, further information on NE prevalence in Thailand is needed. The prevalence of NE and factors associated with it were investigated. Methods. A descriptive study was conducted in schools in Bangkok, Thailand, among children aged 5 to 15 years, using a questionnaire survey between November 2018 and July 2019. Results. The prevalence of primary monosymptomatic, primary nonmonosymptomatic, and secondary NEs was 9.7%, 11.6%, and 8.2%, respectively. Primary NE was associated with a family history of NE (OR = 4.05, P < .001), drinking within 2 hours before bedtime (OR = 1.77, P = .01), and deep sleep (OR = 1.62, P = .001). Conclusion. Primary NE was prevalent in this setting, and the most related factor was a family history of NE. Parents should be aware of NE in their children, especially if a child has a linked factor.
