This survey was conducted to examine the prevalence of sleep disorders in 2-to 12-year-old children in the Beijing area of China. Methods. From October 2001 to June 2002, 5979 children 2 to 12 years old in 6 randomly selected counties in Beijing were investigated with questionnaires. Results. The average total sleep time per day ranged from 11.38 hours among 2-year-olds down to 9.34 hours among 12-yearolds. The overall prevalence of sleep disorders was 21.2%and included parasomnia symptoms (bruxism 6.5% , sleep talking 4.9% , enuresis 1.0% , sleepwalking 0.6% , restless sleep 5.0% , and leg movements 1.9% ) and symptoms of sleepdisordered breathing (frequent snoring 5.6% , mouth breathing 4.1% , chokinggasping 0.9% , and breathing pauses 0.2% ). Conclusion. The overall prevalence of parent-reported symptoms of sleep disorders in a large sample of children in Beijing, China, was comparable to that reported in other countries, although the prevalence of some specific symptoms differed somewhat.展开更多
