This survey was conducted to examine the prevalence of sleep disorders in 2- to 12-year-old children in the Beijing area of China.<\/jats:p>\n               <jats:p>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.<\/jats:p>\n               <jats:p>Results. The average total sleep time per day ranged from 11.38 hours among 2-year-olds down to 9.34 hours among 12-year-olds. 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 sleep-disordered breathing (frequent snoring [5.6%], mouth breathing [4.1%], choking\/gasping [0.9%], and breathing pauses [0.2%]).<\/jats:p>\n               <jats:p>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.<\/jats:p>","DOI":"10.1542\/peds.2004-0815i","type":"journal-article","created":{"date-parts":[[2005,1,4]],"date-time":"2005-01-04T14:47:31Z","timestamp":1104850051000},"page":"266-268","source":"Crossref","is-referenced-by-count":65,"title":["Brief Report: An Epidemiologic Survey of the Prevalence of Sleep Disorders Among Children 2 to 12 Years Old in Beijing, China"],"prefix":"10.1542","volume":"115","author":[{"given":"Xicheng","family":"Liu","sequence":"first","affiliation":[{"name":"From the Department of Respiratory Medicine, Beijing Children's Hospital, Affiliated with Capital University of Medical Sciences, Beijing, People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuyan","family":"Ma","sequence":"additional","affiliation":[{"name":"From the Department of Respiratory Medicine, Beijing Children's Hospital, Affiliated with Capital University of Medical Sciences, Beijing, People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yizhuo","family":"Wang","sequence":"additional","affiliation":[{"name":"From the Department of Respiratory Medicine, Beijing Children's Hospital, Affiliated with Capital University of Medical Sciences, Beijing, People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qinbo","family":"Jiang","sequence":"additional","affiliation":[{"name":"From the Department of Respiratory Medicine, Beijing Children's Hospital, Affiliated with Capital University of Medical Sciences, Beijing, People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaochun","family":"Rao","sequence":"additional","affiliation":[{"name":"From the Department of Respiratory Medicine, Beijing Children's Hospital, Affiliated with Capital University of Medical Sciences, Beijing, People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiuying","family":"Lu","sequence":"additional","affiliation":[{"name":"From the Department of Respiratory Medicine, Beijing Children's Hospital, Affiliated with Capital University of Medical Sciences, Beijing, People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Honghong","family":"Teng","sequence":"additional","affiliation":[{"name":"From the Department of Respiratory Medicine, Beijing Children's Hospital, Affiliated with Capital University of Medical Sciences, Beijing, People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"417","published-online":{"date-parts":[[2005,1,1]]},"reference":[{"key":"2021120819340424300_R1","unstructured":"Liu X, Lin C, Xue Q, Qian Q.
