However, data on school aged children is lacking.Aim: To describe the sleep pattern in school-aged children (6-18 years) referred to a tertiary sleep clinic in Singapore with complaints of snoring.Methods: Data were collected prospectively between years 2000 to 2012 from sleep questionnaires completed by parents, prior to overnight polysomnography. Parent reported bedtime, rise time and sleep duration were analysed. Data on children with evidence of sleep disordered breathing on the sleep study were excluded.Results: 838 children (mean [SD] age = 10 [2.98] years, 70.3% males) were studied. The usual bedtime, rise time and the duration of sleep are summarised in Table 1.View this table:Sleep Pattern in School Aged ChildrenConclusion: School aged children in Singapore with primary snoring have later bedtime and shorter total sleep time than recommended. This may indicate socioeconomic and cultural influences. Whether or not this observation has any impact on health, remains to be determined.
