ABSTRACT
Purpose: To investigate the frequency of childhood sleep problems at pediatric clinics in Seoul and Gyeonggi provinces.
Methods: Children (n=936) and their parents who visited 5 primary and 1 secondary pediatric outpatient clinics were invited to complete a Pediatric Sleep Questionnaire.
Results: Among patients, 901 (96.3%) answered questionnaires in sufficient detail for evaluation. The participants mean age was 4.353.02 years (range, 0–18 years). The male to female ratio was 1:0.93 (466 boys, 435 girls). Habitual snoring (>3 day/week) was reported in 16.9% of the participants. The prevalence of habitual snoring in children <2 years and those between 2–5 years was 9% and 18%, respectively. Sleep disordered breathing was found in 15.1% (106 of 700) of children >2 years. Insomnia was reported in 13.2% of children. The prevalence of sleepwalking, night terrors, and bruxism, is 1.6%, 19%, and 21.1%, respectively. Snoring was associated with increased incidence of sleepwalking, night terrors, and bruxism. Age was associated with insomnia and habitual snoring (P<0.05). Insomnia was more prevalent in younger (21%) than in older children (6%). Snoring was more frequent in both preschool (34%) and school-aged children (33%). The frequency of sleep disordered breathing and insomnia did not vary significantly with gender. However, snoring was more prevalent in boys.
Conclusion: Sleep problems are frequent among children in Korea. Children with snoring have an increased risk of sleepwalking, night terror, and bruxism. Primary clinicians should consider childrens sleep habits to improve their health.
